Impact of Obstructive Sleep Apnea in Patients with Acute Heart Failure: A Nationwide Cohort Study

Background/Objectives: Heart failure presents a significant public health challenge, affecting millions in the US, with projections of increasing prevalence and economic burdens. Obstructive sleep apnea (OSA) is highly prevalent among HF patients. This study analyzes the impact of OSA on the outcomes in patients admitted with acute decompensated heart failure. Methods: We conducted a retrospective cohort study using the National Inpatient Sample database (NIS) 2020, focusing on patients admitted with acute heart failure. Patient outcomes were compared between those with and without a secondary diagnosis of OSA, identified via validated ICD-10 codes. Subgroup analysis was conducted between heart failure patients with reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF). Results: Among 65,649 patients with acute heart failure, 4595 (7%) patients were found to have OSA. The patients with OSA were more likely to be male, older in age and had a higher burden of comorbidities. No significant differences were observed in mortality between heart failure patients with and without OSA. In HFrEF patients, OSA was associated with longer hospital stays (6.45 days vs. 5.79 days, p < 0.001), higher rates of acute kidney injury (AKI) (adjusted odds ratio 1.28, 95% CI: 1.07–1.54, p = 0.007), and atrial fibrillation (adjusted odds ratio 1.35, 95% CI: 1.13–1.61, p = 0.001). In HFpEF patients, an association between OSA and AF was observed (adjusted odds ratio 1.20, 95% CI: 1.01–1.42, p = 0.03). Conclusions: OSA is associated with poor in-hospital outcomes in patients admitted with acute heart failure. HFrEF subgroup is especially vulnerable, with OSA leading to a significant increase in healthcare utilization and complication rates in these patients. This nationwide study underscores the importance of timely identification and treatment of OSA in heart failure to alleviate healthcare burdens and improve patient outcomes.

Patients with crush syndrome and kidney disease: lessons learned from the earthquake in Kahramanmaraş, Türkiye

This study investigated in-hospital outcomes and related factors in patients diagnosed with postearthquake crush syndrome after the earthquakes in Kahramanmaraş, Türkiye. One thousand twenty-four adult patients diagnosed with crush syndrome were analyzed. Data on demographic characteristics, clinical presentation, laboratory values, treatments, and outcomes were collected. A total of 9.8% of patients died during their hospital stay. Nonsurvivors were generally older, more likely to have preexisting chronic kidney disease, and faced more severe injuries and complications, including hypotension-shock, arrhythmias, elevated markers of renal dysfunction, and higher rates of acute kidney injury (AKI) and compartment syndrome. In addition, intensive care unit needs were higher. Multivariate analysis confirmed that age, injury severity, shock, high potassium, uric acid, and lactate levels on admission, development of AKI, compartment syndrome, and intensive care unit admission were significant predictors of mortality. Better disaster preparedness and improved health care infrastructure could be potential explanations for improved in-hospital mortality in the current era, as compared to previous earthquakes.

In-hospital outcomes of cardiac tamponade in patients with pulmonary hypertension: A contemporary analysis.

Cardiac tamponade (CT) has an atypical presentation in patients with underlying pulmonary hypertension (PH). Evidence regarding the impact of PH on CT in-hospital outcomes is lacking. We used the National Inpatient Sample database to identify adult hospitalizations with a diagnosis of CT between 2016 and 2020, using relevant ICD-10 diagnostic codes. Baseline characteristics and in-hospital outcomes were compared in patients with and without a PH. Multivariate logistic regression analyses and case-control matching were performed, adjusting for age, race, gender, and statistically significant co-morbidities between cohorts. A total of 110,285 inpatients with CT were included, of which 8,670 had PH. Patients with PH tended to be older (66 ± 15.7) and female (52.5%), had significantly higher rates of hypertension (74% vs 65%), CAD (36.9% vs. 29.6%), CKD (39% vs 23%), DM (32.1%, vs. 26.9%), chronic heart failure (19.0% vs 9.7%) and COPD (26% vs 18%)(P<0.001 for all). After multivariate logistic regression, PH was associated with higher all-cause mortality (aOR 1.29; 95% CI: 1.11-1.49), higher rates of cardiogenic shock (aOR: 1.19; 95% CI: 1.01-1.41), ventricular arrythmias (aOR: 1.63; 95% CI: 1.33-2.01), longer length of stay (11 days vs 15 days), and higher total hospitalization costs ($228,314 vs $327,429) in patients presenting with CT. Despite pericardiocentesis being associated with lower in-hospital mortality, patients with PH were less likely to undergo pericardiocentesis (aOR: 0.77; 95% CI: 0.69-0.86). PH was associated to increased in-hospital mortality and a higher rate of cardiovascular complications in an inpatient population with CT. Pericardiocentesis was associated with reduced mortality in patients with CT, regardless of whether they had PH. However, patients with PH underwent pericardiocentesis less frequently than those without PH.

Open Reduction and Internal Fixation Is a Feasible Alternative to Femoral Revision Arthroplasty in Geriatric Patients with Vancouver B2/3 Type Periprosthetic Fractures: A Study Analyzing In-Hospital Outcomes.

Purpose: The surgical management of periprosthetic femoral fractures is particularly challenging in geriatric patients due to physiological limitations. The choice between open reduction and internal fixation (ORIF) and hip revision arthroplasty for treating Vancouver B2 and B3 fractures remains controversial. This study aims to contribute further evidence by analyzing the in-hospital outcomes in geriatric patients with Vancouver B2/3 fractures. Methods: This retrospective study analyzed 133 patients treated for Vancouver B2/3 fractures at a level I trauma center from 2017 to 2023. Data were collected on preclinical characteristics, comorbidities, Vancouver classification, surgery-related parameters, and postoperative outcomes for an age- and gender-matched analysis. A subgroup analysis was also conducted on patients classified as American Society of Anesthesiologists (ASA) class 3 and 4. Results: Among the 133 patients, 85 suffered Vancouver B2 fractures and 48 Vancouver B3 fractures. Age-and-gender-matched analysis revealed that ORIF was more commonly performed in patients with higher ASA grades. A subgroup analysis of ASA 3 and 4 patients and an age-and-gender-matched analysis showed that ORIF resulted in shorter operation times and less blood loss. No significant differences were found in mortality or complication rates. Conclusions: ORIF is associated with shorter operation times, less bleeding, and comparable in-hospital outcomes in treating Vancouver B2/3 fractures in higher-risk geriatric patients compared to revision arthroplasty. The retrospective design and small sample size in the ORIF group are limitations of the study. Further studies with functional evaluation are still required.

Impacts of Hospital Volume and Patient-Hospital Distances on Outcomes of Older Adults Receiving Percutaneous Microaxial Ventricular Assist Devices for Cardiogenic Shock.

Background: Percutaneous microaxial ventricular assist devices (pVAD) have the potential to reduce mortality of patients with cardiogenic shock (CS). However, the association between the distribution of pVAD-performing centers and outcomes of CS has not been explored. Methods: This observational study included Medicare fee-for-service beneficiaries aged 65-99 years treated with pVAD for CS from 2016 to 2020 and examined the associations between patient outcomes and two exposure variables: hospitals' procedure volumes of pVAD and patient-hospital distances (in quintiles [Qn]). We developed Cox proportional hazard regression for 180-day mortality and heart failure (HF) readmission rates and multivariable logistic regression for in-hospital outcomes, adjusting for patient demographics, comorbidities, concomitant treatments, and hospital characteristics, including CS volume, teaching status, and the ability to perform extracorporeal membrane oxygenation. Results: A total of 6,637 patients with CS underwent pVAD at 1,041 hospitals, with the annualized hospital volume ranging widely from 0.3 to 55.6 cases/year. Patients treated at higher-volume centers experienced lower 180-day mortality compared with patients treated at lower-volume centers (Qn1=reference; Qn2: adjusted hazard ratio [aHR], 0.88; 95% confidence interval [CI], 0.79-0.97; Qn3: aHR, 0.88; 95% CI, 0.79-0.98; Qn4: aHR, 0.88; 95% CI, 0.78-0.99; Qn5: aHR, 0.84; 95% CI, 0.74-0.95; p-for-trend, 0.026), while we found no evidence that patient-hospital distances were associated with mortality (Qn1=reference; Qn2: adjusted hazard ratio [aHR], 0.99; 95% confidence interval [CI], 0.89-1.09; Qn3: aHR, 0.94; 95% CI, 0.85-1.04; Qn4: aHR, 1.01; 95% CI, 0.92-1.11; Qn5: aHR, 0.91; 95% CI, 0.82-1.01; p-for-trend, 0.160). We found no evidence that the hospital volume and patient-hospital distances were associated with in-hospital bleeding, intracranial hemorrhage, or renal replacement therapy initiation. Conclusions: Hospital volume was more strongly associated with mortality than patient-hospital distances, suggesting that rational distribution of pVAD-performing centers while ensuring adequate procedure volumes may optimize patient mortality.

Impact of clinical features on in-hospital outcomes in premature coronary artery disease patients post percutaneous coronary intervention

Background: Premature coronary artery disease (PCAD) is a significant health concern globally, characterized by the onset of coronary atherosclerosis at an early age. The development of PCAD is influenced by a variety of risk factors and leading to substantial morbidity and mortality. Despite advancements in interventions, the clinical and angiographic characteristics influencing in-hospital outcomes for these patients remain underexplored. Objective: This study aims to investigate the relationship between clinical features and in-hospital outcomes in patients with premature CAD post-percutaneous coronary intervention (PCI) at Dr. Saiful Anwar Hospital. Method: A retrospective cohort study was conducted on 1279 patients who underwent PCI for premature CAD the period of January 2022–December 2023. Clinical information was gathered from medical records, including risk factors and angiographic results. Statistical analyses were conducted using SPSS 22, employing univariate, bivariate, and multivariate logistic regression analyses to determine correlations. Result: The study included 1279 patients, with 438 in the premature CAD group and 841 in the non-premature CAD group. Significant differences were observed in age, sex distribution, BMI, lipid profiles, smoking status, and family history between the groups. Premature CAD patients were younger (mean age 50 vs. 64.8, p&lt;0.001) and had higher rates of smoking and dyslipidemia. Angiographic analysis showed significant differences in LAD and LCx involvement and occlusion rates. In-hospital outcomes indicated higher incidences of shock, cardiac complications, and in-hospital mortality in the non-premature CAD group. Conclusion: Clinical and angiographic characteristics significantly influence in-hospital outcomes for premature CAD patients. Younger age, smoking, and dyslipidemia were prevalent risk factors. Enhanced management strategies focusing on these factors could improve patient outcomes.

Comparison of GRACE and TIMI risk scores in the prediction of in hospital outcome among NSTEMI patients: a single centre study

Abstract Background Major component of ACS, Non-ST segment elevation myocardial infarction (NSTEMI), has more than twice the incidence compared to ST-segment elevation myocardial infarction (STEMI). GRACE (Global Registry of Acute Coronary Events) and TIMI (Thrombolysis in Myocardial Infarction) risk scores are the two most popular prediction models in ACS due to TIMI’s advantage in its simplicity in clinical application and GRACE’s favorable discriminating power. Nevertheless, limited evidence compared the usefulness of these two major risk scores and their association with in-hospital events. Purpose To compare between the predictive ability of GRACE &amp; TIMI risk scores for In hospital outcomes among the NSTEMI patients . Methods This prospective observational study was carried out from 8th march 2020 to 7th March 2022. Total 2152 acute NSTEMI patients were included. Both GRACE &amp; TIMI risk score were calculated. For GRACE score, patients who scored ≤108 points were low risk,109-139 points were medium risk, ≥140 points were high risk . For TIMI scores patients with 0-2 scores were low risk , 3-4 scores were medium risk and 5-7 score were High risk. In Hospital outcomes were defined as the in hospital composite events which includes acute left ventricular failure, cardiogenic shock, arrhythmia &amp; mortality. Results Among the 2152 patients majority were male (73.5%) with mean age of the study population were 58.33 ± .25 years. Mean Grace score &amp; TIMI score of the study population were 137.81±16.38&amp; 3.29±.97 respectively. Most of the patients were categorized in to Medium risk groups by both GRACE &amp; TIMI risk scores , 70% &amp; 51.3% respectively. However, high risk group percentage were higher in GRACE score group(41.3%) in comparison to TIMI score group(10.3%). GRACE score showed better predictive ability than TIMI score for in-hospital outcomes as evaluated by ROC curve( AUC of GRACE vs TIMI, In hospital ALVF:0.89vs 0.59, P&amp;lt;0.001; Cardiogenic Shock 0.72 vs 0.57, P=0.002; Mortality: 0.75 vs 0.59, P=0.002; arrhythmia 0.72 vs0.63, P=0.003). Conclusion GRACE showed better predictive accuracy than TIMI in NSTEMI patients for in-hospital outcomes. The sequential use of TIMI and GRACE scores provide an easy and promising discriminative tool in predicting outcomes in NSTEMI patients , thus improve the identification of high-risk patients.Pic :ROC curve for prediction of ALVFPic: ROC curve for Mortality prediction

The association of obesity and in-hospital outcomes among patients undergoing ablation for atrial fibrillation: a propensity-score matched analysis

Abstract Background Obesity is a strong risk factor for atrial fibrillation (AF), and it can affect the prognosis of AF. However, the impact of obesity (BMI≥30 kg/m²) on postoperative complications after AF ablation has not been extensively studied. We aimed to evaluate the association of obesity with in-hospital outcomes among patients with AF who ablation procedures. Methods The study utilized the National Inpatient Sample (NIS) database 2016-2020. Patients were divided into obese and non-obese groups and matched with propensity score matching (1:1). This matching involved adjusting for baseline variables (including age, gender, primary expected payer, race, and median household income) and comorbidities (including diabetes, hypertension, hyperlipidemia, history of coronary artery bypass grafting (CABG), chronic kidney disease, hyperthyroidism, cardiomyopathy, prior stroke or transient ischemic attack, heart failure with preserved ejection fraction (HFpEF), heart failure with reduced ejection fraction (HFrEF), heart valve disease, coronary artery disease, chronic obstructive pulmonary disease (COPD), alcohol misuse, anemia, and smoking). Furthermore, a weighted analysis was conducted utilizing weights provided by the NIS, and multivariate logistic regression was used to calculate the odds ratio. Results A total of 29,440 patient with AF who underwent ablation were included. After propensity matching, (8,110 in obese and 8,110 in non-obese group) the baseline characteristics were not significantly different between the two groups. Obesity was independently associated with higher risk of pseudoaneurysm, hematoma, postoperative anemia, acute kidney injury, vasopressor need, mechanical ventilation, pulmonary embolism, and ischemic stroke in patients who underwent ablation for AF (Figure 1). In addition, obese group had significantly higher length of stay (median and IQR 2 [1-3] vs 2 [1-4]) and total charges (median and IQR: 131,248$ [95,303-197,784] vs 143,693$ [102,720-206728]) compared to non-obese group (p&amp;lt;0.001). However, in-hospital mortality was not significantly different between the two groups. Conclusion In patients who underwent AF ablation, obesity is associated with significantly higher risk of post-operative complications, as well as increased LOS and total hospital charges.

Effect of empagliflozin on no-reflow in patients with st elevation myocardial infarction undergoing primary percutaneous coronary intervention

Abstract Background Primary percutaneous coronary intervention (PPCI) restores myocardial tissue perfusion successfully in over 90 % of ST-elevation myocardial infarction (STEMI) patients .However there remains a small proportion of patients who exhibit no-reflow.(1) Empagliflozin is a sodium glucose co-transporter 2 (SGLT2) inhibitor that acts as a powerful anti-oxidant and has beneficial effects on endothelial function and reducing burden of ischemia in-vitro.(2) Aim and Objectives: To Assess the effect of Empagliflozin preloading in non-diabetic STEMI patients before PPCI on procedural, in-hospital outcomes and short-term Major Adverse Cardiovascular events (MACE) in a single tertiary center. Patients and Methods: The study was carried out on 200 non-diabetic STEMI patients presenting to our university hospital within the first 8 hours of symptom onset. Patients were randomised into 2 groups , the intervention group received 10mg Empagliflozin before PPCI with the standard medical therapy while the control group received only the standard medical therapy. Patients were assessed for demographic data, risk factors, procedural outcomes, clinical and in-hospital outcomes, and short-term MACE up to 1 month. Results: Our study found a significant difference between the intervention and control groups regarding contrast volume with a mean of 131 ml in the intervention group and 144 ml in control group with a p value of 0.009, incidence of no-reflow with 34.5% in the control group and only 18.2% in the intervention group and a p value of 0.014 and myocardial blush grade (MBG) were 84.1% of the patients in intervention group had MBG III after PCI while only 65.5% of the patients in the control group showed the same results with a p value of 0.019. Also, there was a significant difference in St-segment resolution post PCI as 59.1% of patients in the intervention group had complete ST segment resolution and only 39.1% of the patients in the control group had complete resolution with a p-value of 0.027, and total MACE in the first month which affected 44.8% of the patients in the control group and only 28.4% of those in the intervention group with a p-value of 0.024. Conclusion Our study showed that pre-loading of STEMI patients with Empagliflozin resulted in improvement in procedural outcomes, decreasing the incidence of coronary no-reflow, improvement in patient’s course during hospital stay and short-term MACE. Improvement in MACE was mainly due to reduced HF hospitalisations and anginal symptoms.

Comparative characteristics and invasive management in patients with non-ST elevation acute coronary syndromes in two high-volume hospitals from Romania and Germany

Abstract Introduction Cardiovascular disease (CVD) carries the highest mortality burden across Europe, acute coronary syndromes (ACS) being responsible for most CVD-related deaths. However, significant regional differences in ACS management have been reported. Purpose To describe the characteristics and management of patients with higher-risk non-ST elevation ACS (NSTE-ACS) in 2 high-volume hospitals from 2 European countries with different prevalence of CVD and different income (Germany – GER and Romania – RO). Methods All consecutive invasively managed high and very-high risk NSTE-ACS patients admitted in 2022 in two high-volume hospitals from GER and RO were identified. Patient clinical profiles, coronary anatomy, revascularization strategies, and in-hospital outcomes were compared. Results were adjusted for age and gender. Results 707 patients (345 GER, 66.7% male; 362 RO, 71.5% male; p&amp;gt;0.05) were included. RO patients were younger (65.5 vs. 70.1 years), with higher rates of hypertension (88.7% vs. 82.0%), dyslipidemia (95.6% vs. 81.7%), diabetes (46.1% vs. 34.5%), and active smoking (37.3% vs. 23.5%) (all p&amp;lt;0.05); whereas GER patients had higher rates of atrial fibrillation (36.2% vs. 23.2%), chronic respiratory disease (24.6% vs. 10.5%), sleep apnoea (9.0% vs. 1.4%), thyroid disorders (24.1% vs. 6.4%), and prior revascularization by percutaneous coronary interventions (PCI) (36.5% vs. 20.2%) or coronary artery bypass grafting (CABG) (15.7% vs. 3.0%) (all p&amp;lt;0.05). Mean left ventricular ejection fraction (LVEF) was lower in the RO cohort (43.4% vs. 48%, p&amp;lt;0.001). Rates of myocardial infarction diagnosed by high-sensitivity troponin I assays (88.7% GER, 87.6% RO), and median diagnosis-to-cathlab intervals (12.8 hours GER, 15.5 hours RO) were similar (all p&amp;gt;0.05). In the obstructive coronary artery disease (CAD) group (80.3% GER, 84.3% RO), no differences were found in multivessel disease rates (67.1% GER, 69.8% RO) or mean SYNTAX score (18.6 GER, 16.9 RO) (all p&amp;gt;0.05). For type 1 NSTE-ACS (67% GER vs. 79% RO, p&amp;lt;0.001), PCI represented the main revascularization method (88.3% GER vs. 78.3% RO, p&amp;lt;0.05). Excluding patients with prior CABG undergoing PCI, complete revascularization (residual SYNTAX score ≤8), was reported in 77.1% GER and 84.4% RO of the PCI cases (p&amp;gt;0.05). Intravascular imaging was used in 28.4% of PCIs in GER, and in none in RO. In-hospital mortality (7.0% GER, 6.8% RO), and rates of major adverse cardiovascular events, defined as a composite of death, myocardial infarction, and stroke (8.1% GER, 9.1% RO), were similar (all p&amp;gt;0.05). Conclusions Higher-risk NSTE-ACS patient profiles mirror overall country CVD risk patterns. Compared to Germany, patients in Romania are younger, with a higher CVD risk factor burden, lower LVEF, underdiagnosis of major non-CVD comorbidities, and delayed CAD diagnosis. Despite similar guideline-directed management and in-hospital outcomes in both centres, these aspects may influence the long-term prognosis.

Impact of baseline thrombocytopenia on outcomes in hospitalizations for acute coronary syndrome and non-elective percutaneous coronary intervention: meta-analysis

Abstract Background Thrombocytopenia's impact on acute coronary syndromes (ACS) outcomes is poorly understood. A systematic review and meta-analysis aim to elucidate its influence on both short-term and long-term clinical endpoints, guiding tailored management strategies for improved patient care. Methods Our meta-analysis is registered on PROSPERO (CRD42024511832). We conducted a systematic search of PubMed and SCOPUS databases up to February 2024, utilizing keywords to identify studies on ACS or non-elective PCI populations with or without baseline thrombocytopenia (TP) reporting on in-hospital and long-term outcomes. Baseline TP was defined as a platelet count less than 150 x 10⁹/L and had to be established before hospitalization or ACS management or intervention. Binary random effects models were used to estimate pooled unadjusted odds ratios (OR) and 95% confidence intervals (CI). Sensitivity analysis was done by the leave-one-out method, and the heterogeneity was assessed with the I² statistics. Results From 2,831 identified studies, 10 were identified as eligible for inclusion in our pooled analysis and included 6,588,688 patients. Thrombocytopenia was associated with higher risks of in-hospital mortality (OR=1.89, 95% CI:1.55-2.30, p&amp;lt;0.01), in-hospital Major adverse cardiovascular events (MACE) (OR=1.99, 95% CI:1.63-2.43, p&amp;lt;0.01), and in-hospital bleeding (OR=2.62, 95% CI:1.89-3.64, p&amp;lt;0.01). Long-term follow-up revealed increased risks of MACE (OR=1.80, 95% CI 1.49-2.18, p&amp;lt;0.01), bleeding (OR=1.63, 95% CI:1.63-2.25, p&amp;lt;0.01), and cardiovascular mortality (OR=2.07, 95% CI:1.76-2.42, p&amp;lt;0.01) with thrombocytopenia. No significant difference was found in in-hospital stroke outcomes and long-term outcomes for stroke and recurrent myocardial infarction between thrombocytopenic and non-thrombocytopenic groups. Conclusion Thrombocytopenia worsens ACS outcomes. Vigilance and tailored management are crucial for mitigating its impact on patient prognosis. Further research is needed for better interventions.Secondary outcomes forest plot

Clinical outcomes following debulking atherectomy of calcified left main coronary lesions: a high-volume centre experience

Abstract Introduction Plaque modifying-debulking (PMD) devices are the most effective initial strategy for percutaneous coronary intervention (PCI) of severely calcified lesions including left main coronary artery (LMCA). There is limited data comparing the short and long clinical outcomes of these devices in LMCA lesions. Methods A retrospective analysis of patients with fibrocalcified LMCA lesions treated with PCI with adjunctive PMD devices at a large centre between 2008 and 2021. The primary study endpoint was long-term mortality at documented longest follow-up. Secondary endpoints included procedural complications and inhospital clinical outcome. Results A total of 302 patients with fibrocalcified LMCA lesions treated with rotational atherectomy (RA; n=240), intracoronary lithotripsy (ICL; n=30) or excimer laser coronary atherectomy (ELCA; n=32) were included. Approximately 55% of all patients presented with acute coronary syndromes. Technical success was achieved in 98.7% of patients and procedural success was achieved in 95.4% of patients. At a median follow-up of 42 [19-62] months, there was no difference in mortality between the 3 PMD modalities (RA 54/240 [23.4%] vs. ICL 1/30 [3.3%] vs. ELCA 5/32 [15.6%], P=0.128). Likewise, in-hospital clinical outcomes were similar. However, procedural complications were significantly higher in the ELCA group. Conclusions In patients with fibrocalcified LMCA lesions treated with PCI, adjunctive PMD devices appear safe with survival excceding 80% at long-term follow-up. Our study suggests that ELCA use may be associated with higher procedural risks however this did not increase in-hospital clinical outcomes or long-term mortality risk.

Sex differences in secondary prevention and outcomes post-myocardial infarction in Scotland

Abstract Background Sex differences in outcomes after myocardial infarction (MI) are of increasing interest. Differential receipt of evidence-based treatments may contribute to such disparities. Purpose In this study, we investigate sex differences in the burden of risk factors, in-hospital and long-term treatment and outcomes in contemporary practice in Scotland, by analysing a nationwide sample of consecutive MI admissions. Methods All MI admissions centrally recorded between 2010-2016 by Public Health Scotland were included and followed up until the end of 2021. Poisson regressions analysed in-hospital outcomes (percutaneous coronary intervention (PCI), mortality and post-discharge secondary prevention medication). Models were adjusted for age, co-morbidities and ST-elevation on the electrocardiogram. Royston-Parmar models analysed long-term outcomes (all-cause and cardiovascular mortality, major adverse cardiovascular events (MACE)) and were sequentially adjusted for confounders (age, comorbidities, secondary prevention medications). A 2:1 age and sex-matched general population were included as controls. Results Of a total 47,063 MI patients, 15,776 (33.5%) were women. They were matched with 81,641 controls free of major cardiovascular disease. Median (interquartile range) age was 64 (56-72) years for men and 69 (60-75) years for women. Obesity, hypertension and renal disease were the risk factors more prevalent amongst women, while men had higher rates of previous MI, peripheral vascular disease and atrial fibrillation. Compared to men, women were less likely to undergo PCI (risk ratio (95% confidence interval) – 0.87 (0.86-0.89)) or receive secondary prevention (0.94 (0.93-0.95)), but had similar in-hospital mortality (1.06 (0.99-1.13)), after multi-variable adjustment. Over a median follow-up of 8.4 (6.8-10.2) years, women had higher raw rates of adverse outcomes. However, after full confounder adjustment, this translated into lower risk for women of all cause-mortality 0.92 (0.89-0.95), cardiovascular mortality 0.82 (0.78-0.87) and MACE 0.92 (0.88-0.95) (Figure 1). The female survival advantage was attenuated post-MI in comparison to controls free of significant cardiovascular disease (Figure 2). Conclusions Women and men have different MI risk factor profiles. Women had overall worse crude outcome rates after MI, driven by age and comorbidities. This may have been driven further by undertreatment after MI, including PCI and secondary prevention. Urgent identification of drivers for such disparities in care is warranted in order to improve outcomes and ensure health equity.

Contemporary characteristics, outcomes and novel risk score for Takotsubo cardiomyopathy: a national inpatient sample analysis

Abstract Background Takotsubo cardiomyopathy (TC) is an established differential diagnosis in the category of myocardial infarction with non-obstructive coronaries with significant recent interest but limited data on prognostication. We reviewed the characteristics and in-hospital outcomes and developed a novel risk score for TC. Methods Adult patients (≥18 years of age) with a diagnosis of acute coronary syndrome (ACS) and TC were identified from the National Inpatient Sample 2016-2020 in the United States. The cohort was divided into ACS with and without TC, and the related baseline data was retrieved. Multivariable regression analysis was performed to identify clinical factors associated with TC and its adverse outcomes and to create a risk-scoring system estimating mortality risk in the TC cohort. Results Amongst 7,219,004 adult patients admitted for ACS, 78,214 (1.0%) were diagnosed with TC, with a mean age of 68.2 years, 64,526 (82.5%) being female, and 5,475 (7.0%, compared with 8.4% for other ACS) in-hospital mortality events. Key factors significantly associated with TC diagnosis were female sex (OR 6.78 (95%CI 6.47-7.09), p&amp;lt;0.001) and chronic heart failure (OR 1.60 (95%CI 1.54-1.66), p&amp;lt;0.001). Based on multivariable analyses for in-hospital mortality in TC patients, a novel risk score was developed, with parameters and score assignment listed in the Figure. The score can be divided into three categories: low risk (-3 to +3), moderate risk (4 to 7), and high risk (8 to 19), and its area under curves for in-hospital mortality were 0.716 in the derivation and 0.726 in the validation cohorts. Conclusion TC remains a high-risk diagnosis in a minority of ACS hospitalizations, with comparable in-hospital mortality rates to other causes of ACS. A novel score was developed to risk stratify TC inpatients with moderate discrimination and internal validation, warranting external validation.Takotsubo Cardiomyopathy Risk Score

Comparative insights into type non-A non-B vs type B acute aortic syndromes and their blood pressure management: a monocentric, retrospective, 11-year study

Abstract Background Acute aortic syndromes (AAS) are classified either as type A, if the ascending aorta is involved, or as type B, if only the descending aorta is; AAS affecting the aortic arch, alone or in combination with the descending aorta, have recently been classified as type non-A-non-B (NANB). Few and discordant data are available about the differences between type B and type NANB AAS, especially in terms of presentation, management and prognosis. Little evidence also exists about the effects of blood pressure (BP) management, peaks and variability on in-hospital outcomes in such context. In particular, the largest international AAS registry suggests a comparable course and prognosis, while a recent meta-analysis indicates a poorer clinical outcome with higher rate of complications, need of invasive treatment and mortality in the case of type NANB AAS. Methods We conducted a monocentric, observational, analytical, retrospective registry study including all patients ≥ 18 years old admitted to our tertiary referral hospital with a diagnosis of type B or type NANB AAS from January 2011 to December 2021. Epidemiological, clinical, operative and outcome data were analyzed by comparing type B and type NANB AAS patients. We also focused on systolic and diastolic BP, in terms of both peak values as well as BP variability (BPV); BPV was defined as the difference between the peak and the through value on a certain day. Blood pressure variables were analyzed in relationship with mortality and the failure of an initial conservative management. Results 274 type B and 44 type NANB AAS patients were enrolled. The only significant differences between the two groups were a higher rate of pre-operative complications in type NANB patients (p=0.002) resulting in a higher rate of invasive management (p=0.005), particularly as failure of an initial conservative strategy (p=0.018). However, comparable rates of post-operative complications and in-hospital mortality (overall 7%) were observed. In the overall population, lower limb ischemia, ST segment depression, and post-operative visceral ischemia were associated with higher in-hospital mortality. Peri-aortic effusion was independently associated with failure of conservative management, whereas diagnosis of intramural hematoma (as opposed to other subtypes of AAS) appeared to be protective. Among all BP variables (including anti-hypertensive treatment intensity and daily systolic or diastolic BP peaks and variability), only peak systolic BP on day 5 was found to be non-independently associated with a higher risk of in-hospital mortality and failure of an initially conservative strategy. Conclusions In our study type NANB AAS were more often complicated and treated invasively than type B AAS, while having the same rates of post-operative complications and overall mortality. BP peaks had only a minor effect on outcomes, while BPV and BP management intensity did not have any significant impact.OutcomesBlood Pressure

National trends of left ventricular assist device therapy in Germany

Abstract Background The prevalence of advanced heart failure (HF) is increasing and prognosis remains poor. Although heart transplantation is still considered to be the gold standard for the treatment of advanced HF in selected patients, its use is limited by organ donor shortage and a growing burden of cormorbidities among potential recipients. The 2021 European Society of Cardiology (ESC) guidelines recommend consideration of long-term mechanical circulatory support with a left ventricular assist device (LVAD) in eligible patients with advanced heart failure (HF) who are refractory to medical/device therapy. Purpose The purpose of this study was to evaluate the national trends of LVAD in Germany. The main hypothesis was that LVAD therapy is still underutilized. Methods From the national database of the German Federal Statistical Office (DESTATIS), we identified all patients who underwent LVAD implantation in Germany between January 2011 and December 2022 (n = 9,232). We compared temporal trends and in-hospital outcomes. Results From 2011 to 2022, number of LVAD implantation was highest in the year 2017 (n = 914) and steadily decreased over the following years (2022: n = 617). Mean age of LVAD recipients was 56.2 years (2011-2015) and increased to 58.4 years (2020-2022). The majority of LVAD recipients are male (84,8 %), and this trend has been stable during the entire time period. In-hospital mortality after LVAD remains high, but has been decreasing (25.8% during 2011-2015 compared to 20.2% during 2020-2022). Conclusion Although LVAD is recommended in eligible patients with advanced HF, our study suggests an underutilization of LVAD in this patient population and especially in female patients.

Recent secular trends of catheter-directed therapy for treatment of pulmonary embolism: a retrospective cohort study based on German national data

Abstract Background Various approaches exist for treatment of pulmonary embolism, including systemic lysis, catheter-directed therapy, or anticoagulation. Purpose This study aimed to describe recent secular trends of treatment strategies for patients with pulmonary embolism. Methods Data were interrogated from the Research Data Centre of the German Federal Statistical Office by ICD- and OPS-codes. 800,119 patients with pulmonary embolism, who were treated in German hospitals between 2007 and 2021, were analyzed and grouped according to the therapeutic strategy: no lysis or intervention, systemic lysis, ultrasound-assisted thrombolysis, catheter-directed lysis without ultrasound, retriever system, other transluminal thrombus removal, or surgical thrombectomy. In-hospital outcomes were investigated with focus on the last 8 years. Results Of all patients examined, 37,885 were treated with systemic lysis, 1,383 with ultrasound-assisted thrombolysis, 2,520 with catheter-directed lysis without ultrasound, 181 with a retriever system, 695 with other transluminal thrombus removal, and 1,037 with surgical thrombectomy. There was an increase in all catheter-directed therapies between 2007 and 2021 (from 102 to 735 procedures per year) with more than twice as many procedures from 2019 to 2021 (from 343 to 735 procedures). Between 2014 and 2021, 453,893 patients with main diagnosis of pulmonary embolism were included in the analysis. Mean age was 58.4-68.1 years in the observed groups. 42.5-52.2% were female. Highest rates of cor pulmonale were observed in patients undergoing surgical thrombectomy (87.7%) and systemic lysis (80.1%), which also applied to shock (26.2% and 25.7%), while both rates were lowest in patients without lysis or intervention (cor pulmonale: 25.4%, shock: 1.8%). The overall in-hospital mortality rate was 8.3%, ranging between 6.5% in the ultrasound-assisted thrombolysis group and 38.4% in the systemic lysis group. In catheter-directed therapies, the rate of major bleeding (&amp;gt;5 units of red blood cells) was 4.9%, ranging from 3.1% for catheter-directed lysis without ultrasound to 10.1% for other transluminal thrombus removal. The rate of intracerebral bleeding was 1.4%, with 0.0% for ultrasound-assisted thrombolysis and 4.4% for treatment with a retriever system. Conclusion In recent years, the use of catheter-directed therapy for pulmonary embolism has steadily increased. Rates of in-hospital major bleeding events and intracerebral bleeding were low.

Spontaneous Coronary Artery Dissection (SCAD) with cardiac arrest at presentation: a subanalysis from the DISCO registry

Abstract Introduction Spontaneous coronary artery dissection (SCAD) is a rare cause of acute myocardial infarction (AMI), which primarily affects young women without traditional cardiovascular risk factors, often presenting as sudden cardiac death. This study aims to investigate the prevalence, characteristics, predictors, and outcomes of cardiac arrest in SCAD patients. Methods The DISCO IT/SPA registry, an international retrospective multicenter study, enrolled 375 SCAD patients from 26 centers in Italy and Spain. Patients were categorized based on the presence or absence of cardiac arrest at admission. Data on demographics, clinical presentation, treatment, angiographic findings, and outcomes were collected. Angiograms were independently reviewed, and outcomes included major adverse cardiovascular events (MACE) and in-hospital bleeding. Results Among 375 SCAD patients, 20 (5.3%) presented with cardiac arrest. Both groups were similar in age, gender distribution, and conventional risk factors, except for a lower prevalence of dyslipidemia in the cardiac arrest group. ST-segment elevation myocardial infarction (STEMI) presentation and angiographic type 2b were independent predictors of cardiac arrest. Revascularization was more frequent in the cardiac arrest group. In-hospital outcomes, except for longer hospitalization, did not differ. On follow-up (average 21 months), MACE rates were similar between groups. Conclusions Cardiac arrest is a notable complication in SCAD, mostly presenting with ventricular fibrillation. The prognosis of SCAD patients presenting with cardiac arrest did not differ from those without, reporting a similar rate of events both in-hospital and during long-term follow-up. STEMI presentation and angiographic type 2b were identified as independent predictors of cardiac arrest in SCAD.

In-hospital outcomes of ventricular tachycardia catheter ablation in the presence of intra-cardiac thrombus

Abstract Background Ventricular tachycardia (VT) catheter ablation in the presence of intracardiac thrombi was evaluated in very few studies. Objectives To investigate in-hospital outcomes of VT ablation in the presence of an intracardiac thrombus, in a large inpatient US registry. Methods Using the National Inpatient Sample (NIS) database, patients who underwent non-elective VT catheter ablations in the US between 2016 and 2019 were identified using ICD-10 codes. Sociodemographic, clinical data, in-hospital procedures and outcomes as well as in-hospital mortality were collected. In-hospital outcomes were compared using propensity score (PS) matching analysis with a 1:3 ratio between patients with and without intracardiac thrombus. Results A weighted total of 15,725 admissions for non-elective VT ablation were included in the study, of which 190 (1.2%) had a discharge diagnosis of intracardiac thrombus. Patients with intracardiac thrombus had a higher comorbidity burden and were more likely to have ischemic cardiomyopathy and a diagnosis of cardiac aneurysm. In PS analysis, the presence of intracardiac thrombus was significantly associated with higher rates of any in-hospital complications (42.1% vs 19.3%, P&amp;lt;0.009), driven by higher periprocedural cerebrovascular accident and vascular injury events. In-hospital mortality rates were not significantly different between the groups. Conclusions In patients undergoing non-elective VT ablation, intracardiac thrombus was associated with higher rates of in-hospital complications, but not higher in-hospital mortality. These findings suggest that intracardiac thrombus should not contraindicate VT ablation when deemed necessary, while efforts should be made to decrease potential complications.

Preexisting pulmonary hypertension impact on in-hospital outcomes of cardiac implantable electrical device implantation

Abstract Background Preexisting pulmonary hypertension (PH) is associated with unfavorable in-hospital outcomes in cardiac as well as non-cardiac surgeries and procedures. However, its impact on cardiac implantable electronic device (CIED) implantations is not established. We investigated the extent of preexisting PH among patients undergoing CIED implantations and evaluated its effect on in-hospital outcomes. Methods Using the National Inpatient Sample (NIS) database, we identified patients who were hospitalized in the US between 2016-2019 and underwent CIED implantation with a preexisting diagnosis of PH. Patients with any CIED in-situ were excluded. Sociodemographic, clinical data, in-hospital procedures and outcomes as well as in-hospital mortality were collected. Multivariable logistic regression models were used to identify predictors of in-hospital complications. Results An estimated total of 718,980 patients underwent CIED implantation during the study period. Of them, 74,150 patients (10.3%) had preexisting PH diagnosis. Compared with non-PH patients, PH patients were older, had higher Charlson Comorbidity Index, and more often implanted with implantable cardioverter defibrillators and cardiac resynchronization therapy devices. Higher rate of total complications was observed in PH patients (14.5% versus 9.9%; P&amp;lt;0.001) driven mainly by respiratory complications as well as in-hospital mortality (2.3% versus 1.2%; P&amp;lt;0.001). Multivariable analyses confirmed PH as an independent predictor for respiratory complications, total complications and in-hospital mortality. Conclusion Preexisting PH in patients undergoing CIED implantation was associated with increased risk for respiratory complications as well as in-hospital mortality in a US nationwide, all-comer registry.
