Long-term cardiovascular outcomes of patients experiencing intra-cranial hemorrhage with or without acute cardiovascular events

Abstract Background Acute cardiovascular (CV) events would happen during the acute stage of ischemic stroke or intra-cranial hemorrhage (ICH), so called "Stroke-Heart Syndrome". However, long-term outcomes of patients who experienced acute CV events during the acute stage of ICH were unclear. In the present study, we aimed to report and compare long-term prognosis of patients with or without acute CV events after ICH. Methods A total of 104,955 patients who experienced ICH and survived longer than 90 days without past history of acute myocardial infarction (AMI), heart failure (HF), atrial fibrillation (AF) and ventricular arrhythmia (VA) were identified from the Taiwan National Health Insurance Research Database. Among them, 1,888 patients experienced CV events (AMI, HF, AF or VA) within 90 days after ICH, while 103,067 did not. Results Compared to patients without acute CV events, patients with acute CV events were older (73.53 vs 62.46 years, p<0.001), less males (57.89% vs 61.83%, p<0.001) and had more comorbidities , such as hypertension (77.17% vs 61.58%), diabetes mellitus (35.81% vs 26.54%), vascular diseases (3.5% vs 2.02%) and chronic obstructive pulmonary disease (15.57% vs 9.88%), all p<0.001. Compared to patients without acute CV events, those experiencing acute CV events had a higher adjusted risk of ischemic stroke (adjusted hazard ratio [aHR] 1.564), recurrent ICH (aHR 1.266), HF (aHR 4.693), AF (aHR 19.116), VA (aHR 3.485), AMI (aHR 2.463), sudden cardiac death (aHR 1.609) and mortality (aHR 1.855)(Figure). Conclusions Acute CV events occurring during acute stage of ICH were not a benign course simply related to acute stress and were associated with a poor long-term outcome. How to improve long-term clinical outcomes of these patients deserves more attentions, efforts and studies involving both cardiologists and neurologists.

Effect of baseline and one-year follow-up anemia status on long-term clinical outcomes in patients with heart failure

Abstract Background Anemia is a significant comorbidity in heart failure (HF), influencing patient prognosis and quality of life. In patients with HF, fluctuations in anemia status can markedly impact long-term outcomes. Purpose The aim of this study was to evaluate the long-term prognosis of HF patients according to change in anemia status at the baseline and one-year follow-up. Methods Data were obtained from a multicenter cohort of patients hospitalized for acute heart failure (AHF) from 10 tertiary university hospitals between March 2011 to February 2014. Out of 5,625 AHF patients, the study population was consisted of 1,798 patients with available data on hemoglobin levels at baseline and one-year follow-up. Anemia is defined as hemoglobin levels below 13 g/dL for men and 12 g/dL for women. These patients were then categorized into four groups: group ‘anemia to anemia’; group 2 ‘no-anemia to anemia’; group 3 ‘anemia to no-anemia’; group4 ‘no-anemia to no-anemia’. Primary outcome was the composite incidence of cardiac death or HF readmission. Results Among 1,798 patients, 718 patients (39.9%) died during follow-up (mean 1169.1 ± 880.7 days, median 1057.5 days) and 816 patients (45.4%) developed primary outcome. The patients with baseline anemia had a worse clinical profile than those without anemia. The development of primary outcome tended to significantly decrease from group 1 to group 4 (55.6% vs. 48.1% vs. 40.2% vs. 36.3%, p for trend <0.001). In addition, the incidence of all-cause death, cardiac death, readmission due to cardiac cause, and HF readmission also tended to decrease significantly toward group 4. The cumulative cardiac death or HF readmission free survival rate showed significantly lowest in the group 1 (log-rank p-value < 0.001), and the survival rate increased from Group 1 to Group 4 (Figure). After adjusting for confounding factors, Cox regression analysis showed that anemia to anemia group was independently associated with a 1.368-fold increased risk of primary outcome compared to no-anemia to no-anemia group during follow-up (Hazard ratio [HR] 1.368, 95% confidence interval [CI] 1.110-1.701, p = 0.005). No-anemia to anemia group had also a 1.376-fold increased risk of primary outcome (HR 1.376, 95% CI 1.043-1.814, p = 0.024) compared with no-anemia to no-anemia group. Conclusions In conclusion, the risk of adverse clinical outcomes including cardiac death and HF readmission increased progressively in groups transitioning from no-anemia to anemia or consistently remaining anemic in AHF patients. Conversely, those who improved from anemia to non-anemia or remained non-anemic exhibited a decreased risk, highlighting the critical role of anemia status as a determinant of long-term prognosis. Clinicians should actively manage and monitor anemia as an essential component of treatment strategies to improve long-term outcomes in patients with HF.Kaplan-Meier Survival curve

Clinical characteristics and long-term outcomes of patients with heart failure with supra-normal ejection fraction: data from LECRA-HF registry

Abstract Background Heart failure with preserved ejection fraction (HFpEF) remains insufficiently characterized subgroup of HF with increasing prevalence and limited treatment options. Relationship between clinically assessed left ventricular ejection fraction (LVEF) and survival showed that LVEF ≥65% is associated with higher mortality. Therefore, a novel category of heart failure with supra-normal left ventricular ejection fraction (HFsnEF) was introduced in 2019. However, clinical characteristics and long-term outcomes of HFsnEF patients remain insufficiently elucidated. Purpose We sought to characterize Polish HFsnEF patients and to provide their long-term mortality in comparison to HFpEF. Methods Of 1186 patients enrolled in the single-center Lesser Poland Cracovian Heart Failure (LECRA-HF) Registry between 2009 and 2019 and hospitalized due to HF decompensation 261 (22%) of them were those with LVEF ≥50%. 40 (15.3%) of them were classified as HFsnEF (LVEF ≥65%) and the remaining 221 (84.7%) as HFpEF. The data including patients’ demography, anthropometric measurements, cardiovascular risk factors, prior cardiological treatment and other comorbidities were collected. The long-term follow-up of all-cause mortality was obtained from the Polish National Death Registry. Results HFsnEF patients were less frequently hypertensive (75 vs 88.2%, P=0.026) and had higher baseline LVEF (65 [65-70] vs 55 [50-60] %, P<0.001) than HFpEF subjects. Furthermore, HFsnEF patients presented lower INR (1.1 [1-1.6] vs 1.3 [1.1-1.9], P=0.027) and total protein level (57 [25-63] vs (65.2 [60.2-69.9] g/L, P=0.008) on admission. HFsnEF patients were less frequently treated on discharge with mineralocorticoid receptor antagonists (25 vs 46.2%, P=0.013) as well as loop diuretics (60 vs 76%, P=0.017). The Kaplan-Meier analysis showed that all-cause mortality is higher in HFsnEF than in HFpEF (65.0 vs 55.2%, P=0.044, Figure 1). The independent predictors of long-term mortality were age and diagnosis of HFsnEF (HR 1.037, 95% CI 1.018-1.056 and HR 1.665, 95% CI 1.063-2.608, respectively). Conclusions Our findings indicate that every seventh Polish patient admitted with HFpEF could be classified as HFsnEF. Baseline characteristics of HFsnEF patients are different than HFpEF. Simultaneously, the HFsnEF diagnosis is associated with lower long-term survival.

Prevalence, characteristics, and long-term outcomes of patients with mitral annular disjunction undergoing surgery for degenerative mitral regurgitation

Abstract Background Mitral valve prolapse (MVP) is associated with progressive mitral regurgitation (MR) requiring surgical repair. A subset of patients with MVP may also suffer from malignant ventricular arrhythmias (VAs), especially in the presence of mitral annular disjunction (MAD). Purpose To assess the prevalence, associated characteristics, and long-term outcomes of patients with MVP with and without MAD undergoing mitral valve surgery for degenerative MR. Methods Patients with MVP and moderate-to-severe or severe degenerative MR undergoing mitral valve surgery between 2010-2022 at a university hospital in Sweden were included. MAD length was measured on echocardiograms at end-systole from the insertion of the posterior leaflet on the detached mitral annulus to the border of the bulging left ventricle. Patient demographics and clinical outcomes were collected from medical records. The primary endpoint consisted of VAs, defined as sustained- or non-sustained ventricular tachycardia or high burden of premature ventricular complexes causing hospitalizations or ablation or identified at Holter monitoring. Other endpoints included sudden cardiac death, all-cause mortality, new onset postoperative atrial fibrillation, stroke, mitral valve reoperation, endocarditis, new or worsened heart failure, myocardial infarction and implantation of permanent pacemaker or cardiac defibrillator. Results Of 599 patients undergoing mitral valve surgery, 96 (16%) had preoperative MAD, with a median (Q1, Q3) MAD length of 8.0 (5.0-10.0) mm. Compared with patients without MAD, patients with MAD were younger (55 vs 63 years), more likely to be female (31% vs 17%), to have diffuse myxomatous valve disease (66% vs 25%) and bileaflet prolapse (57% vs 17%). Most patients underwent mitral valve repair (84% vs 80%). No patient had residual MAD after surgical repair. At a mean follow up time of 5.8 ± 3.5 years after mitral valve repair, VAs were more common in patients with pre-operative MAD (10% vs 2% (adjusted HR 4.52, 95% CI 1.57-13.0)) (Figure 1). There were no significant differences in the risks of other clinical outcomes. Conclusions MAD was associated with almost a 5-fold increased long-term risk of VAs after mitral valve repair despite successful anatomical correction of MAD. These findings highlight the importance of increased awareness of VAs in patients with MAD also after mitral valve surgery.

Impact of real-world off-label dose of Apixaban on long-term clinical outcomes in patients with atrial fibrillation and chronic kidney disease

Abstract Background Apixaban represent one of the cornerstone treatments to prevent cardioembolic events in patients with nonvalvular atrial fibrillation (NVAF). However, the choices of Apixaban dose guided by the decision-making process of the physician, which considers specific according to kidney functions are inconsistent in the real-world practice. Objective The objective of the present study is to evaluate the effects of real-world Off-label dose of Apixaban on long-term clinical outcomes in NVAF patients with chronic kidney disease (CKD). Methods Our database of AF patients diagnosed with CKD from 2018 to 2023 was used to obtain laboratory, echocardiography, electrocardiogram (ECG), and clinical outcomes data. Inclusion criteria were all AF patients with CKD using Apixaban. And we compared bleeding, systemic thrombotic events including stroke/systemic embolism and death according to off-label real -world dose of Apixaban. Results Among 635 patients with AF and CKD (76.9±10.4 years), 335 (52.8%) patients took off-label underdosed Apixaban. Difference in the baseline characteristics was not observed among patients including CHA2DS2 VASc score and HASBLED score. During the median 18-month follow-up, a lower incidence of bleeding events (P=0.001) was observed in the off-label underdosed Apixaban group compared to those with standard dose or off-label overdosed Apixaban. However, there was no significant difference of systemic thrombotic events including stroke/systemic embolism and death according to off-label real-world dose of Apixaban (off-label underdose vs. standard dose, P=1.000; off-label overdose vs. standard dose, P=1.000; off-label underdose vs. off-label overdose, P=0.609). In multivariate analysis, HASBLED score was independent risk factors for bleeding events (OR 9.650; CI 1.998-46.622; P=0.005). Conclusions Compared with standard or off-label overdose of Apixaban, off-label underdose of Apixaban was associated with a lower risk of bleeding in patients with AF and CKD, with no difference in the risk of stroke/systemic embolism or death, supporting the apixaban dosing tailored to specific clinical features and drug pharmacokinetics of the Asian patients.

Sex differences in clinical characteristics, phenotypes, management, and long-term outcomes of myocardial injury: an international cohort study

Abstract Background Several studies have demonstrated sex differences in patients presenting to the emergency department (ED) with myocardial infarction, heart failure or syncope. Whether sex-specific differences in chest pain patients with myocardial injury exist is unknown. Purpose To determine whether sex-specific differences in the clinical characteristics, phenotypes, management, and long-term outcomes of patients with myocardial injury exist. Methods Patients presenting to the ED with chest pain suggestive of MI were consecutively enrolled into a prospective multicenter international diagnostic study. Final diagnoses were centrally adjudicated by two independent cardiologists, applying the fourth universal definition of myocardial infarction, using all available medical records, including serial hs-cTn and cardiac imaging. Follow-ups were performed at 3 months, 1-, 2- and 5-years. The primary outcome was 5-year all-cause mortality. Secondary outcomes included 5-year cardiovascular mortality and non-cardiovascular mortality. Multivariable flexible parametric (Royston-Parmar) models assuming proportional hazards were fitted. Models were adjusted for age, history of coronary artery disease, history of malignancy, diabetes, hypertension, smoking status, history of liver disease, and renal function. Results Among 8046 chest pain patients presenting to the ED, 1158 (14.4%) had myocardial injury, of which 358 (31%) were females and 800 (69%) males. Women were older (79 years, vs. 73 years), had fewer cardiovascular risk factors and comparable non-cardiovascular comorbidities except for lung disease which was more commonly found in men. Myocardial injury phenotypes varied between sexes (Figure). The most common phenotype in both sexes was heart failure, yet it was more common in men (37.2%) than in women (22.3%). The second most common phenotype in women was hypertension (15.4%) and arrhythmia (15.4 %), while in men was myocarditis (17.8 %), followed by arrhythmia (15.8%). Women underwent less invasive coronary angiography (19.8% vs 26.9%) or stress testing (12% vs 21.5%). In the angiographic findings, women presented more often with normal findings (30.4% vs. 19.6%) or mild CAD (20.3% vs. 11.2%) whereas men displayed more frequently 3-vessel disease (14.5% vs. 36.4%), Table. After adjusting for known confounders, women were associated with a lower 5-years risk for all-cause mortality (HR 0.69; 95%CI: 0.56–0.83) and cardiovascular mortality (HR 0.61; 95%CI: 0.46–0.79). No statistically significant difference in non-cardiovascular mortality risk was found (HR 0.79; 95%CI: 0.59-1.04). Conclusions Women presenting with chest pain to the ED and having myocardial injury were less likely than men to undergo coronary angiography or non-invasive cardiac imaging. Long-term risk for all-cause or cardiovascular mortality was lower for women compared to men.Myocardial Injury phenotypesPatient management

Long term outcomes of patients with decompensated aortic stenosis undergoing urgent transcatheter aortic valve implantation: a TAVI-NOR subs-study

Abstract Background Aortic stenosis (AS) is a progressive disease, which untreated leads to irreversible myocardial damage and potentially death. Patients with AS may present with acute decompensation (ADAS) even during active surveillance. Purpose In this TAVI-NOR sub-study, we investigate the clinical profile, risk factors, epidemiology and long-term outcomes of patients treated with TAVI after presenting with ADAS compared to stable patients who underwent elective TAVI (no ADAS). Method A total of 600 patients with severe AS consecutively treated with TAVI between January 2012 and July 2019 were enrolled in TAVI-NOR study. Predictors and long-term clinical outcomes were explored in binary logistic and Cox regression models. Results A total of 68 patients (11.3%) received urgent TAVI due to acute hospitalization with ADAS. Age (80±8.0 years vs 81±6.0 years, p=0.662), gender (56% males vs 50% males, p=0.361) and other comorbidities at baseline such as cardiovascular disease, chronic lung disease and atrial fibrillation (AF) were comparable in patients with ADAS and no ADAS (n=532) (p>0.05 for all). However, patients with ADAS had greater symptom burden (NYHA III-IV 81% vs 51%, p<0.001), lower blood pressure, higher heart rate and lower estimated glomeruli filtration rate (52.0±10.8 vs 54.6±9.8 mL/min/1.73m2, p<0.045). They had also higher prevalence of ECG left ventricular (LV) hypertrophy (40% vs 27%, p=0.027), more often reduced LV ejection fraction (<50%) (41% vs 16%, p<0.001), lower stroke volume (39±11 ml/m2 vs 42±11 ml/m2 vs, p=0.030) a trend of abnormal ECG (p=0.055) and longer hospital stay (11.5 ±8.7 days 6.6± 4.9 days, p<0.001). Patients with ADAS were comparable with no ADAS in terms of early short-term (<30 days) all-cause mortality (p>0.05). Although 1-year mortality was comparable (1.5% in ADAS vs 2.1% in no ADAS, p>0.99), mid- to late-term mortality rates were significantly higher in patient with ADAS receiving urgent TAVI, with 3-, 5- and 7 years mortality of 22% vs 11%, p=0.008; 46% vs 29%, p=0.005; 53% vs 39%, p=0.033, respectively. In a Kaplan-Meier analysis, event-free survival was significantly reduced for patients with ADAS undergoing urgent TAVI compared with stable patients undergoing elective TAVI HR 1.63, 95% CI 1.15-2.31, p=0.006), confirmed by a multivariable-adjusted model (HR 1.54; 95% CI 1.05-2.25, p=0.026) independent of age, gender, AF, LV ejection fraction and time from diagnosis to TAVI (Fig). Conclusion Patients with AS presenting with acute decompensation and treated with urgent TAVI had excellent short-term survival. This was irrespective of increased symptom burden, adversely remodeled and functionally reduced LV at baseline. These findings might explain the observed higher mid- and long-term mortality compared with stable patients undergoing elective TAVI. It is essential to identify patients at risk of acute decompensation and treat them timely before irreversible myocardial damage occur.

Infective endocarditis - characteristics and long-term outcomes in patients with congenital heart disease are distinct from those without congenital heart disease

Abstract Background Patients with congenital heart disease (CHD) form a high-risk niche among patients considered at high-risk of infective endocarditis (IE). Their life-long exposure to the risk of IE, starting from birth, necessitates a nuanced approach to both prevention and treatment strategies. However, comprehensive data from an unselected nationwide cohort, including children, are lacking. Purpose This study sets out to compare characteristics and associated outcomes among patients with IE with and without CHD. Methods Using nationwide registries, all Danish patients diagnosed with IE from 1977-2021 were identified and stratified on whether they had a diagnosis of CHD, regardless of its complexity. Characteristics prior to and during admission as well as associated outcomes (i.e., in-hospital mortality, 1-year mortality, and 10-year mortality, and IE recurrence) were compared between groups. Results In total, 14,040 patients were diagnosed with IE from 1977-2021 including 895 (6.4%) with a diagnosis of CHD. Patients with versus without CHD were significantly younger at time of IE diagnosis (median age 38.8 years [IQR 21.2-56.4 years] versus 70.7 years [IQR 58.8-78.9 years], Figure 1) and less comorbid. Patients with versus without CHD were hospitalized due to IE for a similar period of time but more often underwent cardiac surgery during admission (44.9% versus 21.3%). The IE-related bacteremia was significantly different between groups: the most common bacteriemia in relation to IE was Streptococci (29.9%) in patients with CHD and Staphylococcus Aureus (29.9%) in patients without CHD. Patients with CHD were associated with a significantly lower risk of in-hospital mortality (6.4% versus 19.8%), 1-year mortality (10.5% versus 32.4%) and 10-year mortality (21.3% versus 58.7%) compared with those without CHD. The 10-year incidence of IE recurrence was similar among groups (p-value 0.5). Conclusions Patients with CHD who develop IE are distinctive from patients with IE without CHD in terms of characteristics as well as long-term outcomes. Notably, our findings stress a key point: the majority of children and adolescents with IE have a CHD. These unselected findings should help guide future preventive strategies, diagnosis, and management.

Maintenance of sinus rhythm is associated with lower incidence of stroke in patients with drug-refractory atrial fibrillation

Abstract Introduction Recent studies have demonstrated that early rhythm control for first-line treatment of atrial fibrillation (AF) improved cardiovascular outcomes. However, there is limited data regarding the long-term outcome of patients who failed antiarrhythmic drugs and who refuse radiofrequency catheter ablation (RFCA). Methods Patients with AF who were refractory to antiarrhythmic drugs and had refused further rhythm control attempts via RFCA were retrospectively identified and propensity-score matched with who had been treated with RFCA. The primary outcome of interest was all-cause mortality or ischemic stroke. Results A total of 169 patients who refused rhythm control with RFCA and propensity-score matched 169 patients who had been treated with RFCA were included for analysis. During a mean follow-up of 4.3[2.3;6.9] years, maintenance of sinus rhythm was more achieved in RFCA group (7 [4.1%] in Refuse group vs. 133 [78.7%] in RFCA group, p<0.001). the incidence of ischemic stroke was significantly higher in patients who refused RFCA compared with patients who underwent RFCA (24 [14.2%] vs. 6 [3.5%], log-rank p<0.001), but all-cause mortality was not significantly different (log-rank p=0.8). Refusal of attempted rhythm control via RFCA was an independent risk factor for ischemic stroke on multivariate Cox analysis (hazard ratio 3.2; 95% confidence interval 1.2 to 8.53, p=0.02). The risk of major adverse cardiovascular events (MACE) were also significantly higher in Refuse group (31 [18.3%] vs. 12 [7.1%], HR 3.83, 95% CI 1.57-9.37, p=0.003). Conclusion In patients with antiarrhythmic drug-refractory AF, maintenance of sinus rhythm was significantly different dependent on rhythm control via RFCA, therefore the risk of stroke was significantly higher in patients who refused rhythm control via RFCA compared with that of those treated with RFCA.

Sex differences in outcomes among patients undergoing transcatheter atrial septal defect closure: Do they benefit equally?

Abstract Background Although sex differences in congenital heart disease are prevalent and relevant, there is limited research on their role in atrial septal defect (ASD) closure. We aimed to investigate sex differences in baseline characteristics, procedural and long-term outcomes of patients with transcatheter ASD closure. Methods Data from adult patients undergoing ASD closure between 2005-2016 were retrospectively analyzed. Results Of the 853 patients included, 281 (32.9%) were male and 572 (67.1%) were female. Females were more symptomatic at presentation than males (p < 0.001). Males had a higher frequency of cardiovascular comorbidities than females (p < 0.001). Although echocardiographic right ventricular (RV) diameter relative to body surface area was equal in males and females (2.49 cm/m2 versus 2.57 cm/m2; p = 0.072), males had more RV dysfunction (12.1% versus 7.6%; p = 0.028). In contrast, females had higher RV systolic pressures (39.71 mmHg versus 37.23 mmHg; p = 0.025), and were more likely to have moderate to severe tricuspid regurgitation (15.4% versus 8.9%; p = 0.007). Males had larger defects with use of larger implants (p < 0.05). Procedure-related complications were rare and did not differ by sex. At 12-month follow-up, both male and females showed comparable decreases in RV diameter (-0.57 cm versus -0.59 cm; p = 0.751), RV systolic pressure (-4.57 mmHg versus -6.31 mmHg; p = 0.094), and severity of tricuspid regurgitation (p = 0.173; Figure). After a mean follow-up of 3 years (SD = 5), no significant differences were observed in the incidence of death (incidence rate ratio (IRR) = 0.49 [95% CI 0.27-0.83]; p = 0.402), new onset atrial fibrillation (IRR = 3.22 [95% CI 2.57-3.99]; 0.063), cardioversion or ablation (IRR = 0.40 [95% CI 0.20-0.71], p = 0.335), stroke/TIA (IRR = 0.29 [95% CI 0.12-0.56]; p = 0.745), and pacemaker implantation (IRR = 0.29 [95% CI 0.12-0.57], p = 0.728). Conclusions Although patient profiles differed by sex, procedural and long-term outcomes were comparable, suggesting that transcatheter ASD closure can be safely performed in both males and females.Figure.Sankey Plot

Long-term outcomes of patients with apical hypertrophic cardiomyopathy: incorporation of a novel risk score

Abstract Background Apical hypertrophic cardiomyopathy (aHCM) is a subtype of HCM characterized by left ventricular hypertrophy predominantly in the apex. There is still limited data on factors associated with adverse outcomes in patients with aHCM. Objectives To a) describe the characteristics and b) develop a novel risk score associated with outcomes in aHCM patients. Methods A total of 462 patients (mean age 58±15 years, 68% male and 70% white) diagnosed with aHCM based on clinical, echocardiographic, and cardiac magnetic resonance (CMR) evaluation were included. The primary endpoint was all-cause death or aborted sudden cardiac death. Using the cox regression analysis, variables showing potential association with the composite endpoint were considered to develop an aHCM specific risk score. Results On echocardiography, the mean LV ejection fraction (LVEF) was 64±8%, and the mean LV mass was 223±72 g. A baseline CMR was performed in 246 (53%) patients, with delayed gadolinium enhancement in 170 (71%) patients with a mean percentage of 5±7%. Patients were followed-up for a mean of 68 months (range 1-248), with composite events occurring in 80 (17%) patients (death in 62 [13%] patients). Univariate Cox regression analysis identified age hazard ratio (HR) 1.06 (95% Confidence Interval or CI 1.04-1.08; p< 0.001), apical aneurysm HR 2.32 (95% CI 1.24-4.34 p=0.008), lower LVEF HR 0.96 (95% CI 0.94-0.99 p=0.002), higher right ventricular systolic pressure (RVSP) HR 1.04 (95% CI 1.02-1.06 p< 0.001), New York Heart Association Class IV HR 11.69 (95% CI 3.59-38.08 p< 0.001) and the presence of Atrial fibrillation HR 1.77 (95% CI 1.14-2.76 p=0.012). An aHCM specific risk score was subsequently created (Figure 1), with good discrimination (c-statistic=0.75) and good calibration with expected to observed ratio of 1.02 and a calibration slope of 0.91 (p-value for difference between expected and observed probabilities =0.22). The risk score ranges between 0 and 8 points, with higher score associated with a higher rate of composite events (Figure 2). Conclusion We developed a novel risk score which demonstrated incremental prognostic value for hard events in aHCM patients.Risk prediction modelKaplan Meier event-free survival curves

Long-term outcomes in women with a history of peripartum cardiomyopathy

Abstract Background Peripartum cardiomyopathy (PPCM) remains an important cause of cardiac-related maternal morbidity and mortality in previously healthy young women. Data on the long-term clinical course of PPCM are sparse. In this study, we report the long-term outcomes in patients with PPCM. Methods and Results Long-term follow-up (median 9.6, min 5, and max 24 years) was available in 72 women with PPCM followed in a cardio-obstetrics clinic. Five-year follow-up data were available for 19 PPCM patients, 10-year follow-up data for 24 PPCM patients, and more than 15 years of follow-up data for 24 PPCM patients. Seven patients were lost to cardiac follow-up but are known to be alive. The mean age at diagnosis was 35 ± 7 years, and 85% were Caucasian. The mean parity was 2.2 ± 1.3, and gravidity was 2.7 ± 1.7. Twin pregnancies were reported in 13% of cases. Pre-eclampsia was present in 25% of the patients and the development of hypertension in the long-term was documented in 18%. The mean LVEF was 34.5 ± 9.9% at diagnosis. One-year LVEF data were available in 72 patients: 54 patients (75%) experienced LV recovery (LVEF≥ 50%). After 1 year, the mean LVEF was 53.4± 8.2%. Among patients remained with LV<50% at one year (n=10) no LV function recovery was reported at long-term follow-up. At a median follow-up of 9.6 years (n=66) mean LVEF was 52.1±10.4%, nine patients had a reduction in LVEF (<50%) function in the long-term follow-up with a mean LVEF of 46.1± 2.1%. Out of 72 PPCM patients, 3 patients developed arrhythmia, in one woman coronary artery disease occurred and 7 underwent pacemaker implantation. Almost half of patients (n=65) remained with long term treatment of b-blockers, 38% received medications for hypertension or heart failure. No cases of myocardial infarctions, cardiovascular death, or heart transplantations were reported. Two women died during follow-up: one with normal LVEF died from breast cancer, and another patient with reduced LVEF and severe diabetes. The cause of her death remained unclear. During follow-up, 30 women had ≥ 1 subsequent pregnancy (SSP), and there was no reduction in their mean LVEF before SSP 57.0 ± 5.4% and at long-term follow-up was 59.6± 1.3% (p=ns). Conclusion Our study demonstrates favorable long-term outcomes with high and stable recovery rates with low mortality rates, and no impact of subsequent pregnancies on the clinical course of the condition. Nevertheless, persisting or new diagnosis of hypertension and use of cardiovascular medications were noted in the long term follow up.

LV reverse remodeling after SAVR in patients with severe symptomatic aortic stenosis: impact on the clinical outcome

Abstract Introduction Surgical aortic valve replacement (SAVR) is the treatment of choice for young patients with severe aortic stenosis (AS) and low surgical risk. Left ventricular (LV) reverse remodeling (RR) after surgery is expected to occur. However, this is not always the case following afterload relief, and this may impact the prognosis. We aimed to assess the prognostic effect of distinct definitions of LV RR after SAVR in the long-term outcome of patients with severe AS. Methods Single-centre prospective study including patients referred for SAVR due to severe symptomatic AS, with no previous history of ischemic cardiomyopathy. Both pre- and post-operative transthoracic echocardiographic (TTE) and cardiac magnetic resonance (CMR) study (at the 3rd to 6th month after SAVR) were performed. LV RR was defined when in presence of at least one of the imaging criteria: >15% decrease in end-diastolic volume (EDV) by CMR; >15% decrease in LV indexed mass (LVM) by CMR; >10% decrease in geometric remodeling (LV mass/EDV ratio) by CMR; >10% increase in LV ejection fraction (LVEF) by CMR; >50% increase on global longitudinal strain (GLS) by TTE. We assess the prognostic value of RR definitions for the outcome after SAVR using Cox regression and Kaplan-Meier analysis. The primary endpoint was defined as all-cause mortality, heart failure (HF) hospitalization or worsening HF. Results We enrolled 140 patients – mean age 71±9 years-old, 49% male, predominantly high-gradient-normal flow AS (mean gradient 65±18mmHg, aortic valve area 0.7±0.2cm2, index stroke volume 47±11mL/m2) submitted to SAVR. At a mean follow-up (FUP) of 34±12 months, 23 (16%) patients met the primary endpoint: 4% (5 patients) died immediately after surgery; three patients died at the FUP (overall mortality rate of 6%). 12 patients (9%) were admitted for HF and 7 (5%) had at least one episode of worsening HF. 118 patients had complete pre and post-surgery imaging study (mean FUP: 36±10 months): 103 patients (87%) had at least one RR parameter (Table 1). Post-operative RR was not independently associated with the clinical outcome (Figure 1A). LVM was the sole independent predictor of the outcome at univariate analysis (Figure 1B–F). Conclusions LV RR after SAVR is highly prevalent in a cohort of patients with classical severe symptomatic AS. However, only LVM regression independently predicts the clinical outcome after surgery. This may stand the greater importance of structural reverse remodeling, rather than LV functional improvement, after pressure overload relief.

Ten-year outcomes in patients with hypertension and primary hyperaldosteronism undergoing surgical adrenalectomy versus medical therapy: data from the multinational collaborative network TriNetX

Abstract Background Surgical adrenalectomy for resection of adenomas has been the standard approach for treating patients with secondary hypertension due to primary hyperaldosteronism. However, few studies explored long-term outcomes in patients treated with adrenalectomy when compared to patients treated with conservative management. Purpose To compare ten-year mortality and cardiovascular outcomes in patients with primary hyperaldosteronism treated with surgical adrenalectomy versus patients with primary hyperaldosteronism treated with medical therapy alone. Methods This retrospective cohort study used real-world data from healthcare organizations participating in the global health research collaborative network TriNetX. We performed propensity score matching for demographic and clinical characteristics and calculated hazard ratios, comparing 2.397 patients in each group. The outcomes were all-cause death, heart failure, and the composite endpoint ischemic stroke, hemorrhagic stroke, myocardial infarction, unstable angina, and aorta aneurysm or dissection (major adverse vascular events) during the 10-year follow-up. Results Patients undergoing surgical adrenalectomy had a lower incidence of all-cause death (3.0%) when compared with patients in medical therapy (5.0%) ( hazard ratio 0.60, 95% CI 0.45-0.81). Patients in the surgical group had a 4.6% incidence of heart failure and the medical therapy had an 8.6% incidence of heart failure (hazard ratio 0.54, 95% CI 0.42-0.69). The incidence of major adverse vascular events was lower in the surgical group (10.9%) compared to the medical therapy group (14. 1%) ( hazard ratio 0.76, 95% CI 0.65-0.90). Conclusion In patients with hypertension and primary hyperaldosteronism, surgical adrenalectomy was associated with lower 10-year mortality, heart failure, and major adverse vascular events compared to medical therapy alone.

Baseline characteristics, management patterns and outcome in patients with pulmonary embolism and malignancy: Insights from a single-centre study

Abstract Background and aim The presence of malignancy is an important factor that increases the risk of venous thromboembolism. On the other hand, acute pulmonary embolism (PE) is one of the main causes of death in this setting. In this study, we evaluated the impact of active malignancy on the treatment choices, and short and long term clinical outcomes in patients with acute PE. Methods In this study conducted in a tertiary center, 872 acute PE patients (age 61.6±16.8 years, female 57.5 %) from different risk categories were treated with thrombolytic, anticoagulant and catheter-based therapies in accordance with currently available acute PE guidelines. The population was retrospectively analyzed and divided into two groups according to the presence of active malignancy. Results Active malignancy was documented in 129 (14.8 %) patients. In the groups with and without malignancy, the proportions of low-, intermediate-low-, intermediate-high-, and high-risk PE patients were 3.1 % vs. 15.6 %, 17.8 % vs. 16.7 %, 60.5 % vs. 60 %, and 18.6 % vs. 7.7 %, respectively (p<0.001). While the two groups did not differ in terms of echocardiographic and computed tomographic pulmonary angiography (CTPA) characteristics, the presence of contraindications for thrombolytic were more frequent in the malignancy group (22.5% vs. 10.9%, p<0.001). Ultrasound-assisted thrombolysis (USAT), rheolytic thrombectomy (RT), systemic thrombolysis (ST) and anticoagulation-alone (AC) therapies were noted in 27.3 %, 6.4 %, 6.4 % and 49.7 % of overall PE patients. The RT and AC therapies were more frequent in PE patients with malignancy whereas ST and USAT were more frequently used in the absence of malignancy. Notably, lytic dosages and treatment durations in USAT and ST protocols were comparable between malignant and non-malignant PE cohorts. Regardless of the presence of malignancy and the treatment modality chosen, significant improvements were achieved in the clinical, echocardiographic and CTPA measures of the PE severity (p<0.001 for all). Major and minor bleeding rates were also similar in both groups, while in-hospital and, as expected, long-term mortality were higher in the malignancy cohort. Active malignancy and PESI score were found to be independent predictors for composite end-point of 60-day mortality and PE-related rehospitalization (adjusted odds ratio (OR): 2.43; 95 % CI: 1.32 - 4.47, p=0.04) and (OR: 1.02; 95 % CI: 1.01-1.01, p<0.001), respectively. Malignancy (OR: 3.5, 95 % CI: 2.15-5.75, p< 0.001) and chronic obstructive pulmonary disease (OR: 2.51, 95 % CI: 1.35-4.68, p< 0.003) were independent predictors of long-term mortality. Conclusion Concomitant malignancy adversely affects both short- and long-term outcomes in patients with acute PE. Although these patients are more vulnerable, it is possible to achieve satisfactory treatment success with acceptable bleeding rates with the inclusion of catheter-based methods as treatment option.Survival plot

Long-term outcomes in patients with dual pathology aortic stenosis and cardiac amyloidosis referred for valve intervention

Abstract Background The coexistence of aortic stenosis (AS) and cardiac amyloidosis (CA) is common. If treated with transcatheter aortic valve implantation (TAVI), patients with the combined phenotype (AS-CA) have a comparable short term survival to those with lone AS, whereas data on longer term outcomes is currently lacking. Purpose This study aimed to evaluate the clinical outcomes of AS-CA compared to lone AS over a 5-year follow-up. Methods Using a prospective, multicentre, observational, case-control design, we screened consecutive patients with severe AS referred for TAVI for co-existing CA. CA screening included blinded 99mTc-DPD bone scintigraphy (Perugini Grade-0 negative, 1-3 increasingly positive) with additional SPECT/CT and light chain assessment prior to intervention. Transthyretin CA (ATTR) was diagnosed by bone scintigraphy and unremarkable light chain assessment, light-chain CA (AL) by endomyocardial biopsy. Mortality (all-cause and cardiovascular [CV]) and hospitalisation for heart failure (HHF) were captured as clinical endpoints. Results 376 patients (83±7 years, 52% female, EuroSCORE-II 4.9±2.9) were recruited, of which 43 (11.4%) had AS-CA (42 ATTR, 1 AL). Compared to lone AS, patients with AS-CA were older with higher cardiac biomarkers (NT-proBNP, high-sensitive Troponin-T) and a higher prevalence of atrial fibrillation. Heart team decision yielded valve replacement in 320 (85%) and conservative management in 56 (15%) patients, without differences between AS-CA and lone AS. Over a median follow-up of 5.4 (Q1: 4.9; Q3: 5.7) years, 230 (61.1%) patients died and 67 (17.8%) experienced HHF (with a total HHF number of 91). AS-CA was associated with higher all-cause mortality (crude HR 1.64, 95%CI 1.15-2.35; log-rank, p=0.006), which remained significant after multivariate adjustment for clinical confounders (EuroSCORE-II, valve replacement; adjusted HR 1.63, 95%CI 1.15-2.32; p=0.006). AS-CA was not associated with CV mortality (log-rank, p=0.18) or time to first HHF (log-rank, p=0.43), but the rate of HHF was significantly higher in AS-CA compared to lone AS (5.7 versus 3.5 per 1,000 patient years, p=0.022). Conclusions Among elderly patients referred for TAVI, long-term outcomes of AS-CA are characterized by higher mortality and a higher rate of heart failure hospitalisations compared to patients with lone AS. Studies evaluating the role of CA-specific treatments are warranted in this population.

Platelet-large cell ratio predicts no-reflow in patients undergoing primary coronary angioplasty for ST-segment elevation myocardial infarction

Abstract Background Increased platelet indices have been shown to reflect higher degree of platelet activation and have been related to poorer short- and long-term outcomes in patients presenting with ST-segment elevation myocardial infarction (STEMI). Purpose We aimed to evaluate the ability of a validated marker of platelet activation (i.e., the platelet-large cell ratio [P-LCR]) to predict the occurrence of no-reflow in patients undergoing primary percutaneous coronary intervention (pPCI) for STEMI. The ability of P-LCR to predict other markers of thrombotic charge (i.e., use of glycoprotein IIb/IIIa inhibitors and/or thrombus aspiration) was also investigated. Methods Use of glycoprotein IIb/IIIa inhibitors and/or thrombus aspiration, occurrence of the ‘no-reflow’ phenomenon and P-LCR values on admission were recorded in 836 consecutive patients treated by pPCI for STEMI. Patients’ demographic data and symptom onset-to-cardiac catheterization laboratory time intervals were also recorded. Correlations between P-LCR values and the presence of thrombotic charge markers were evaluated. Results No-reflow occurred in 124 (14.8%) of the study patients; glycoprotein IIb/IIIa inhibitors and thrombus aspiration were used in 228 (27.3%) and in 289 (34.5%) of patients, respectively. Mean P-LCR values were 27.1 ± 7.6%. P-LCR values on admission were significantly higher in patients who presented no-reflow than in those who did not (29.1 ± 5.6% vs. 25.3 ± 5.8%, p = 0.03). Similarly, P-LCR were significantly higher in patients in whom glycoprotein IIb/IIIa inhibitors (29.5 ± 6.1% vs. 25.2 ± 5.3%, p = 0.04) and/or thrombus aspiration (28.4 ± 5.7% vs. 24.8 ± 5.4%, p = 0.03) were used. A P-LCR value ≥26.9% predicted the occurrence of no-reflow with 70.9% sensitivity and 55.4% specificity (p = 0.04). Conclusions In the present cohort, P-LCR values on admission predicted the presence of thrombotic charge markers in patients undergoing pPCI for STEMI. Evaluating P-LCR on admission could help identify patients at increased risk of no-reflow, in whom more intensive antiplatelet strategies may be of interest.

Clinical characteristics and outcomes of patients with takotsubo syndrome and dynamic left ventricular outflow tract obstruction

Abstract Background Left ventricular outflow tract obstruction (LVOTO) is recognized as a serious complication of Takotsubo syndrome (TTS). However, its impact on patient prognosis remains insufficiently investigated. Purpose This study aimed to assess clinical characteristics and short- and long-term outcomes of patients with TTS complicated by LVOTO. Methods Patients with TTS were enrolled from the Takotsubo Italian Network (TIN). The primary outcome was the composite of acute heart failure, cardiogenic shock, and mortality during hospitalization. Secondary outcomes included the single components of the primary outcome and the occurrence of death or TTS recurrence during follow-up. Results Overall, 881 patients were included in the study [median age 72.0 (63.0–78.0) years; 91.3% female], with LVOTO detected in 59 patients (6.7%). Low diastolic blood pressure, ST-segment elevation, and moderate-to-severe mitral regurgitation were independently associated with occurrence of LVOTO. Propensity score weighting regression analysis revealed a significant higher risk of the primary outcome (OR, 2.99; 95% CI, 2.22–4.02), acute heart failure (OR, 2.19; 95% CI, 1.59–3.02), cardiogenic shock (OR, 4.56; 95% CI, 3.07–6.78), and in-hospital mortality (OR, 2.42; 95% CI, 1.13–5.21) in patients with TTS complicated by LVOTO. No significant association between LVOTO and long-term mortality or TTS recurrence was observed during follow-up. Conclusions In this real-world evidence study, LVOTO was detected in about 7% of TTS patients and was associated with a significantly higher risk of adverse events during hospitalization, including mortality. Early detection of LVOTO can aid in prognostic assessment and guide therapeutic management in patients with TTS.

Multi-dimensional assessment of long-term outcomes in patients treated with extracorporeal cardiopulmonary resuscitation during refractory cardiac arrest

Abstract Background Recent randomised controlled trials showed short-term survival benefits with extracorporeal cardiopulmonary resuscitation (ECPR) compared to standard cardiac arrest treatment in selected patients with refractory cardiac arrest. Only limited data exist on multi-dimensional long-term outcomes after ECPR. Purpose To investigate multi-dimensional long-term outcomes of ECPR survivors, that is general health status, as well as cardiac, cognitive and psychological functions. Methods This is a multicenter, mixed-method clinical study conducted by cardiologists, neurologists and psychologists between May 2021 and December 2023. Adult patients who survived ECPR with veno-arterial extracorporeal membrane oxygenation (VA-ECMO) or "ECMELLA" (i.e., VA-ECMO plus percutaneous left-ventricular assist device) in two German tertiary care centers were included. A comprehensive set of functional outcomes across multiple dimensions were assessed at approximately 18 months after the index cardiac arrest event (see Figure for stations A to E and explanation of abbreviations). Results Long-term outcomes were assessed in 32 ECPR survivors, out of whom 15 patients (46%) had received VA-ECMO and 18 (54%) ECMELLA treatment. 23 patients (70%) were male and the average age was 55 years (±13). Vital signs and laboratory markers were unremarkable. Most patients denied heart failure symptoms although the average EQ-5D-5L score was 52 (±8). The left-ventricular ejection fraction was 51% (±9), which improved by 14% (±11) in the ECMO group and 31% (±15) in the ECMELLA group since the index cardiac arrest event. Bicycle exercise (on average 6 minutes duration with a power of up to 100 Watts) and 6-minute walk test (average distance of 394 meters ±145) revealed physical impairments. 29 patients (88%) had a good cerebral performance (i.e., Cerebral Performance Category scale of 1) and the average mental status was good (mini–mental state examination score 29 ±1). 22 patients (56%) perceived (partial) impairments in activities of daily living although the average Barthel index was 100 (±5) and modified Rankin scale was 1 (±1). 12 patients (36%) were unable to return to their jobs. Remarkably, 17 (51%) and 4 (12%) patients reported depressive symptoms and suicidal thoughts, respectively. Conclusion Although ECPR remains a highly complex procedure, cardiac and neurologic functions in survivors have almost recovered, while physical and psychological impairments still persisted at 18 months after cardiac arrest. Physical rehabilitation and psychological care appear to be important measures for ECPR survivors.

Health-related quality of life and long-term incidence of major adverse events in patients with acute coronary syndromes

Abstract Background Assessing health-related quality of life (HRQoL) in patients with acute coronary syndromes (ACS) could provide insight into predicting major adverse cardiovascular events (MACE) and all-cause death. Purpose To investigate the association of baseline HRQoL and its change within the first year post-ACS with the incidence of MACE and all-cause death. Methods Participants in the SPUM-ACS study, a multicenter cohort of patients hospitalized for ACS at four Swiss university hospitals from 2007 and 2021 and followed-up for a median duration of 6.6 years, were evaluated for HRQoL at baseline and one-year post-discharge using the EQ-5D-3L index and visual analogue scale (VAS). The EQ-5D-3L index is derived from five health dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). Baseline HRQoL and its change within the first year post-ACS, alongside the individual health dimensions, were analyzed in relation to the risk of subsequent MACE (composite of myocardial infarction, stroke or transient ischemic attack, coronary revascularization, and cardiovascular death) and all-cause death using Cox proportional hazards models, adjusting for sociodemographic, lifestyle factors, and medical history. Results 2499 patients with ACS (mean age 62±12 years, 80% males), primarily undergoing percutaneous coronary revascularization, were included. Over a median follow-up of 6.6 years, 25% experienced MACE and 13% died from any cause. Overall, HRQoL improved in the first year post-ACS, with the EQ-5D-3L index increasing from 0.74 to 0.81 and the VAS from 68 to 76 (p<0.001). At baseline, 80% reported some problem in at least one health dimension, mainly anxiety/depression (36%), pain/discomfort (35%), and mobility (27%). By the first year, 58% had no problem or improved in one or more dimensions; however, 38% declined in at least one dimension, particularly in pain/discomfort (26%), or anxiety/depression (16%). The baseline VAS, but not EQ-5D-3L index, was inversely associated with the hazard of subsequent MACE and all-cause death (HR=1.06 [1.01, 1.11] per 0.1-unit and 1.10 [1.03, 1.19] per 10-unit decrease, respectively). Problems with pain/discomfort were associated with MACE (HR=1.20 [1.00, 1.44]); and mobility, self-care and usual activities with all-cause death (HR=1.36 [1.04, 1.79], 1.44 [1.04, 1.98] and 1.37 [1.04, 1.80], respectively) (Figure 1). First-year EQ-5D-3L index and VAS change were inversely associated with the hazard of MACE (HR=1.11 [1.04, 1.18] per 0.1-unit and 1.16 [1.07, 1.25] per 10-unit decrease) and all-cause death (HR=1.13 [1.04, 1.23] per 0.1 and 1.17 [1.06, 1.30] per 10-unit decrease, respectively) (Figure 2). Conclusion HRQoL at baseline and its change within the first year after ACS are associated with the risk of adverse events, suggesting HRQoL might be a valuable predictive indicator for long-term outcomes in patients with ACS.Figure 1Figure 2
