Independent Predictor Of All-cause Death Research Articles

Impact of coronary artery disease on outcome after transcatheter edge-to-edge mitral valve repair with the MitraClip system.

The clinical impact of coronary artery disease (CAD) on the prognosis of patients undergoing MitraClip implantation is still unclear. One thousand nine hundred fifty-three patients undergoing MitraClip implantation included in the multicenter GIOTTO Registry were stratified according to CAD. Endpoints were all-cause death, cardiac death, and re-hospitalization for heart failure at follow-up (median 15.8 months). Although younger, CAD patients were more symptomatic, had worse cardiovascular risk profile, higher burden of comorbidities, more frequently affected by functional MR, with higher left ventricle (LV) diameters and lower ejection fraction (EF). At follow-up, CAD patients showed higher rates of all-cause death (25.4% vs. 19.6%; P=0.002), cardiovascular death (14.0% vs. 10.1%; P=0.007) and re-hospitalization for heart failure (13.9% vs. 10.2%; P=0.011). Dividing the population according to mitral regurgitation (MR) etiology (functional vs. non-functional MR), no differences were observed between CAD and no-CAD patients. At multivariate logistic regression, NYHA III/IV class, prior heart failure hospitalization, severe chronic kidney disease, atrial fibrillation, LV end-diastolic diameter and LVEF<30% but not CAD resulted independent predictors of all-cause death. The same finding was confirmed even after propensity score adjustment. CAD did not show a relevant impact on mid-term prognosis per se, but seemed to identify a more complex and diseased cohort of patients with worse clinical and functional status.

Visit-to-Visit Heart Rate Variability in the Prediction of Clinical Outcomes of Patients with Atrial Fibrillation.

Visit-to-visit heart rate variability (VVV-HR) has been associated with adverse cardiovascular outcomes. We aimed to determine the predictive value of VVV-HR for adverse clinical outcomes in patients with nonvalvular atrial fibrillation (AF). We used data from a prospective multicenter AF registry of 27 hospitals in Thailand during 2014 to 2017. After the baseline visit, patients were followed up every 6 months until 3 years. VVV-HR was calculated from the standard deviation of heart rate data from baseline visit and every follow-up visit. VVV-HR was categorized into four groups according to the quartiles. Clinical outcomes were all-cause death, ischemic stroke/systemic embolism (SE), and heart failure. Cox proportional hazard models were used for multivariable analysis. There were a total of 3,174 patients (mean age: 67.7 years; 41.8% female). The incidence rates of all-cause death, ischemic stroke/SE, and heart failure were 3.10 (2.74-3.49), 1.42 (1.18-1.69), and 2.09 (1.80-2.42) per 100 person-years respectively. The average heart rate was 77.8 ± 11.0 bpm and the average of standard deviation of heart rate was 11.0 ± 5.9 bpm. VVV-HR Q4 was an independent predictor of all-cause death, ischemic stroke/SE, and heart failure with adjusted hazard ratios of 1.45 (95% confidence interval: 1.07-1.98), 2.02 (1.24-3.29), and 2.63 (1.75-3.96), respectively. VVV-HR still remained a significant predictor of clinical outcomes when analyzed based on coefficient of variation and variability independent of mean. VVV-HR is an independent predictor for adverse clinical outcomes in patients with AF. A J-curve appearance was demonstrated for the effect of VVV-HR on all-cause death.

Impact of right coronary artery dominance on the long-term mortality in the patients with acute total/subtotal occlusion of unprotected left main coronary artery

BackgroundPatients with a right dominant coronary artery anatomy account for a significant proportion of acute myocardial infarction cases, and this condition is associated with a better prognosis. However, there are limited data on the impact of coronary dominance on patients with acute total/subtotal occlusion of unprotected left main coronary artery (ULMCA). MethodsThis study aimed to assess the impact of right coronary artery (RCA) dominance on long-term mortality in patients with acute total/subtotal occlusion of the ULMCA. From a multicenter registry, 132 cases of consecutive patients who had undergone emergent percutaneous coronary intervention (PCI) due to acute total/subtotal occlusion of the ULMCA were reviewed. ResultsPatients were classified into two groups according to the size of their RCA (dominant RCA group, n = 29; non-dominant RCA group, n = 103). Long-term outcomes were examined according to the presence of dominant RCA. Cardiopulmonary arrest (CPA) occurred in 52.3 % of patients before revascularization. All-cause death was significantly lower in the dominant RCA group than in the non-dominant RCA group. In the Cox regression model, dominant RCA was an independent predictor of all-cause death, as well as total occlusion of ULMCA, collateral from RCA, chronic kidney disease, and CPA. Patients were further analyzed according to the degree of stenosis of the ULMCA; patients with non-dominant RCA and total occlusive ULMCA had the worst outcome compared with the other groups. ConclusionsA dominant RCA might improve long-term mortality in patients with acute total/subtotal occlusion of the ULMCA who were treated with PCI.

Growth Differentiation Factor 15: A Prognostic Marker in Patients with Acute Chest Pain without Acute Myocardial Infarction.

Acute chest pain is associated with an increased risk of death and cardiovascular events even when acute myocardial infarction (AMI) has been excluded. Growth differentiation factor-15 (GDF-15) is a strong prognostic marker in patients with acute chest pain and AMI, but the prognostic value in patients without AMI is uncertain. This study sought to investigate the ability of GDF-15 to predict long-term prognosis in patients presenting with acute chest pain without AMI. In total, 1320 patients admitted with acute chest pain without AMI were followed for a median of 1523 days (range: 4 to 2208 days). The primary end point was all-cause mortality. Secondary end points included cardiovascular (CV) death, future AMI, heart failure hospitalization, and new-onset atrial fibrillation (AF). Higher concentrations of GDF-15 were associated with increased risk of death from all causes (median concentration in non-survivors vs survivors: 2124 pg/mL vs 852 pg/mL, P < 0.001), and all secondary end points. By multivariable Cox regression, GDF-15 concentration ≥4th quartile (compared to <4th quartile) remained an independent predictor of all-cause death (adjusted hazard ratio (HR): 2.75; 95% CI, 1.69-4.45, P < 0.001), CV death (adjusted HR: 3.74; 95% CI, 1.31-10.63, P = 0.013), and heart failure hospitalization (adjusted HR: 2.60; 95% CI, 1.11-6.06, P = 0.027). Adding GDF-15 to a model consisting of established risk factors and high-sensitivity cardiac troponin T (hs-cTnT) led to a significant increase in C-statistics for prediction of all-cause mortality. Higher concentrations of GDF-15 were associated with increased risk of mortality from all causes and risk of future CV events.

Serum neurofilament light chain in functionally relevant coronary artery disease and adverse cardiovascular outcomes

Background: Functionally relevant coronary artery disease (fCAD), causing symptoms of myocardial ischemia, can currently only be reliably detected with advanced cardiac imaging. Serum neurofilament light chain (sNfL) is a biomarker for neuro-axonal injury known to be elevated by cardiovascular (CV) risk factors and cerebrovascular small-vessel diseases. Due to their pathophysiological similarities with fCAD and the link to CV risk factors, we hypothesised that sNfL may have diagnostic and prognostic value for fCAD and adverse cardiovascular outcomes. Methods: Of the large prospective Basel VIII study (NCT01838148), 4’016 consecutive patients undergoing cardiac work-up for suspected fCAD were included (median age 68 years, 32.5% women, 46.9% with history of CAD). The presence of fCAD was adjudicated using myocardial perfusion imaging single-photon emission tomography (MPI-SPECT) and coronary angiography. sNfL was measured using a high-sensitive single-molecule array assay. All-cause and cardiovascular death, myocardial infarction (MI), and stroke/transient ischaemic attack (TIA) during 5-year follow-up were the prognostic endpoints. Results: The diagnostic accuracy of sNfL for fCAD as quantified by the area under the curve (AUC) was low (0.58, 95%CI 0.56–0.60). sNfL was strongly associated with age, renal dysfunction, and body mass index and was a strong and independent predictor of all-cause death, cardiovascular death, and stroke/TIA but not MI. Time-dependent AUC for cardiovascular-death at 1-year was 0.85, 95%CI 0.80–0.89, and 0.81, 95%CI 0.77–0.86 at 2-years. Conclusion: While sNfL concentrations did not show a diagnostic role for fCAD, in contrast, sNfL was a strong and independent predictor of cardiovascular outcomes, including all-cause death, cardiovascular death and stroke/TIA.

Sex Differences in Quality of Life and Clinical Outcomes in Patients with Heart Failure

Background: Heart failure (HF) is generally associated with poor quality of life (QoL). Limited data are available characterizing health-related QoL (HRQL) in Chinese patients with HF. Methods: We used the Minnesota Living with Heart Failure Questionnaire (MLHFQ) to record QoL in 4082 patients with HF from China who were followed up over 12 months in the Heart Failure Registry of Patient Outcomes (HERO) study. Baseline HRQL and differences in QoL between women and men with heart failure were compared. We used multivariable Cox regression with adjustment for variables to assess the association between MLHFQ summary scores and a composite of all-cause mortality and HF hospitalization. Result: At baseline, the mean MLHFQ in the overall population was 42.9 ± 19.57; the scores for physical and emotional domains were 22.0 ± 8.69 and 8.66 ± 6.08, respectively. Women had a higher (poorer) MLHFQ summary score (44.27 ± 19.13) than men (41.63 ± 19.90) (P&lt;0.001). Female patients also had higher MLHFQ physical and emotional scores than male patients (P&lt;0.001). The specific scores of the questionnaire were higher in women than men. NYHA class was the strongest independent predictor of MLHFQ score (β=6.12 unit increment; P&lt;0.001). Sex was not independently associated with higher MLHFQ scores after multivariable adjustments. The 12-month mortality in the overall cohort was 19.6%, the hospitalization rate was 24.4%, and the composite endpoint was 40.15%. A 10-point increase in MLHFQ score was associated with higher risk of mortality (female and male HRs=1.19 [95% CI 1.12–1.26]; P&lt;0.001 and 1.18 [95% CI 1.12–1.24]; P&lt;0.001, respectively) and composite outcomes (HRs=1.08 [95% CI 1.04–1.13]; P&lt;0.001 and 1.11 [95% CI 1.07–1.14]; P&lt;0.001, respectively). Females did not show a significant association between HRQL and hospitalization (HR=1.04 [95% CI 0.99–1.09]; P=0.107). Conclusion: Quality of life was largely poorer in women than men, but was similar between sexes in terms of physical burden and emotional limitation. HRQL is an independent predictor of all-cause death and HF hospitalization in patients with HF.

Role of modified hydration for preventing contrast-associated acute kidney injury in patients with ST-segment elevation myocardial infarction after primary percutaneous coronary intervention

To assess the efficacy of modified hydration on contrast-associated acute kidney injury (CA-AKI) in ST-segment elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (pPCI). A total of 438 patients were randomly assigned to 2 groups. The traditional hydration group (group I) was given at a rate of 1 ml/kg/h for 24 h, and the modified hydration group (group II) was given at a rate of 3 ml/kg/h in the first 4 h, and then reduced to 1 ml/kg/h for 12 h. 0.3 mg/kg of furosemide was given 1-h after hydration. The primary endpoint was the incidence of CA-AKI, and the secondary endpoint was the incidence of major adverse cardiovascular events (MACEs) during a median of 22.4 months (IQR 9.6, 32.6 months) follow-up. The incidence of CA-AKI was 8.7%. Among these, Group I was 9.1% and group II was 8.2%, respectively. There was no significant difference in CA-AKI and creatinine levels between the two hydration groups. Multivariable logistics regression analysis revealed that creatinine, white blood cells, and N-terminal pro-B-type natriuretic peptide were associated with CA-AKI. Moreover, CA-AKI was an independent predictor for all-cause death and cardiac death during the follow-up period. The modified hydration may reduce the incidence of CA-AKI, although this difference was not statistically significant. The relationship between CA-AKI and mortality strengthened as creatinine times above baseline increased. Mitigating the occurrence of CA-AKI may reduce all-cause death and cardiac death.

Relationship between systolic blood pressure and renal function on clinical outcomes in patients with atrial fibrillation: a report from the AF-GEN-UK registry

Abstract Background European guidelines on AF management recommend a systolic blood pressure (SBP) target of 120–129 mmHg as this level is associated with the lowest risk of poor outcomes. Elevated blood pressure and AF both negatively affect renal function, but the interactions between SBP and renal function in patients with AF remains unclear. In the UK extension of the EURObservational Research Programme (EORP) Long-term Registry of patients with atrial fibrillation (AF) [AF-GEN-UK study], we assessed the combined impact of BP levels and renal (dys)function on mortality, thromboembolic and haemorrhagic events. Methods 1580 patients (60.1% males, mean (SD) age 70.6 (11.2) years) from the AF-GEN-UK registry had SBP available at baseline and were stratified into groups based on SBP: 120–129 mmHg (reference group, n=289), &amp;lt;100 mmHg (n=165), 110–119 mmHg, (n=254), 130–139 mmHg (n=321), 140–159 mmHg (n=385), and ≥160 mmHg (n=166). Impact of SBP, renal function and their interaction on 1-year outcomes were assessed using Cox regression analysis, adjusted for age, oral anticoagulation (OAC) use and CHA2DS2-VASc score. SBP groups were compared by ANOVA (continuous data) and Chi-square test (categories) with two tailed p&amp;lt;0.05 deemed significant (STATA Corp, version 13). Results Overall OAC use was 84% and was similar between all SBP groups. Renal function (eGFR), was preserved across SBP groups; those with SBP 110–119 mmHg had the lowest level. Prevalence of heart failure was highest in those with SBP &amp;lt;110 mmHg. Patients with uncontrolled SBP (&amp;gt;140 mmHg) were older, more likely female and higher rates of hypertension, with correspondingly higher CHA2DS2VASc scores. SBP &amp;lt;100 mmHg (Hazard Ratio (HR) 2.36; 95% confidence intervals (CI) 1.20–4.64) and lower eGFR (HR 0.99; 95% CI 0.98–0.996) were associated with all cause-death in univariate analyses. Adjusted Cox regression revealed that SBP &amp;lt;100 mmHg and OAC use were independent predictors of all-cause death (Table). No interaction between BP groups and eGFR was evident. OAC use (aHR 0.31; 95% CI 0.11–0.92) was associated with a reduced risk of thromboembolic events. Conclusion In anticoagulated patients with AF, SBP &amp;lt;110 mmHg was independently predicted of all-cause death, with no interaction with kidney function. No independent association of SBP groups with haemorrhagic and thromboembolic events was evident. OAC therapy was associated with a significant reduction in all-cause death and thromboembolic events.

Prognostic value of rest B-lines with the simplified 4-site scan for predicting survival: incremental value over transthoracic echocardiography

Abstract Background Lung ultrasound (LUS) detects pulmonary congestion as B-lines at rest. Methods After preliminary exclusion of 154 patients lost to follow-up, we analyzed transthoracic echocardiography (TTE) plus LUS (4-site simplified scan) data in 5165 subjects (age 64±11 years) referred to 19 certified centers of 9 countries for known or suspected coronary artery disease (n=3891, 75%), dyspnea (n=591, 12%), or screening in asymptomatic patients with risk factors (n=667, 13%). We analyzed the anterior and lateral hemi-thoraces, scanning from mid-axillary to mid-clavicular lines on the third intercostal space. B-lines score ranged from 0 (normal) to 40 (severely abnormal). By selection, follow-up information was available in all. All-cause death was the predetermined end-point. Results Feasibility of B-lines was 100% in all subjects. B-lines (median) were 0.1 [0–1]. Rest B-lines (≥2) were present in 863 patients (16.7%). Ejection fraction was 61±10%. After a median follow-up of 690 (Interquartile range 420–1065) days, 96 all-cause deaths occurred. Two-year mortality was 3.6% in patients with and 1.5% in patients without B-lines (p&amp;lt;0.001) and increased progressively with the increasing number of B-lines, from 2.4% in mild (2–4, n=630), 5.0% in moderate (5–9, n=160) and 8.2% in patients with severe (≥10, n=73) B-lines (see figure). At multivariable analysis, rest B lines (HR 1.812, 95% CI: 1.165–2.916, p=0.008) and ejection fraction (HR 0.987, 95% CI: 0.976–0.998, p=0.020) were independent predictors of all-cause death, in addition to age (HR 1.045, 95% CI: 1.023–01.067, p&amp;lt;0.001) and diabetes (HR 1.643, 95% CI: 1.079–2.503, p=0.021). Conclusion In all-comers referred for TTE, resting B-lines assessed by focused LUS with the simplified 4-site scan are detected in 1 out of 4 patients with symptos or coronary risk factors and are associated with worse survival. The severity of pulmonary congestion predicts the severity of outcomes. The prognostic value of resting B-lines is independent and additive over standard clinical and TTE predictors such as diabetes and ejection fraction. Focused LUS for pulmonary congestion can easily be incorporated in standard TTE examination. Funding Acknowledgement Type of funding sources: None.

Clinical and prognostic significance of left ventricular outflow tract velocity time integral (LVOT-VTI) in patients with chronic heart failure

Abstract Background The echocardiographic evaluation of cardiac output relies on the product of the flow across the left ventricular outflow tract (LVOT), estimated through its velocity time integral (LVOT-VTI), and its cross-sectional area, estimated through the formula πr2. Considering the geometrical assumption behind such formula, LVOT-VTI has been proposed as a more reproducible surrogate of cardiac systolic function and showed prognostic value in the critical care setting. However, the role of such measure in patients with chronic heart failure (HF) remains unexplored. Objective To assess the clinical and prognostic significance of LVOT-VTI in a contemporary cohort of patients with chronic HF. Methods Outpatients with chronic HF with a LV ejection fraction &amp;lt;50% were prospectively enrolled to undergo a clinical, echocardiographic, and biohumoral assessment, and were followed-up for the endpoint of all-cause death. Results Finally, 971 patients were enrolled (71±12 years, 72% men, 50% ischemic etiology, LVEF 35±9%). Most patients showed a NYHA class I-II (74%) and were treated with ACE-inhibitors/ARBs or ARNI (81%), beta-blockers (95%), and mineralocorticoid receptor antagonists (71%). Patients were distinguished in three subgroups according to LVOT-VTI tertiles &amp;lt;19 (n=324), 19–24 (n=324), or ≥24 (n=323). Compared with the other two subgroups, patients with LVOT-VTI &amp;lt;19 showed worse NYHA class, lower LVEF and tricuspid annular plane systolic excursion (TAPSE), and higher E/e', left atrial volume index (LAVi), estimated systolic pulmonary arterial pressure (sPAP), and NT-proBNP concentration (all p&amp;lt;0.001). No differences were observed as for patients' age, HF etiology, and therapies (all p&amp;gt;0.05). Over a median follow-up of 22 (9–34) months, 103 (11%) patients met the primary endpoint. LVOT-VTI significantly stratified the risk of death, observing 65 (20%), 21 (7%), and 17 (5%) events across the subgroups with values &amp;lt;19, 19–24, or ≥24 (log-rank 33, p&amp;lt;0.001). At multivariable regression analysis, LVOT-VTI &amp;lt;19 (HR 2.06 [95% 1.21–3.49], p=0.008), but not LVEF &amp;lt;30% (p=0.614) was an independent predictor of all-cause death in a model adjusted for age, sex, ischemic etiology, renal function, hemoglobin, E/e', LAVi, TAPSE, sPAP, and NT-proBNP. Conclusion LVOT-VTI is associated with disease severity and is a strong predictor of all-cause death in patients with chronic HF. Funding Acknowledgement Type of funding sources: None.

Reduced Left Ventricular Ejection Fraction Is a Risk for Sudden Cardiac Death in the Early Period After Hospital Discharge in Patients With Acute Myocardial Infarction.

The incidence of sudden cardiac death (SCD) after discharge in Japanese acute myocardial infarction (AMI) patients with reduced left ventricular ejection fraction (LVEF) treated with primary percutaneous coronary intervention (PCI) remains unknown.Methods and Results:The study population included 1,429 AMI patients (199 with LVEF ≤35% and 1,230 with LVEF >35%) admitted to the Hirosaki University Hospital, treated with primary PCI within 12 h after onset, and survived to discharge. LVEF was evaluated in all patients before discharge, and the patients were followed up for a mean of 2.6±0.8 years. The Kaplan-Meier survival curves revealed LVEF ≤35% was associated with all-cause death and SCD. The incidence of SCD was 2.6% at 1 year and 3.1% at 3 years in patients with LVEF ≤35%, whereas it was 0.1% at 1 year and 0.3% at 3 years in patients with LVEF >35%. Sixty-seven percent of SCDs in patients with LVEF ≤35% occurred within 4 months after discharge, and the events became less frequent after this period. A Cox proportional hazard model indicated LVEF ≤35% as an independent predictor for all-cause death and SCD. The incidence of SCD was relatively low in Japanese AMI patients treated with primary PCI, even in patients with LVEF ≤35% upon discharge. Careful management of patients with reduced LVEF is required to prevent SCD, especially in the early phase after discharge.

FT3/FT4 ratio is correlated with all-cause mortality, cardiovascular mortality, and cardiovascular disease risk: NHANES 2007-2012.

BackgroundThyroid hormones play a vital role in maintaining the homeostasis of the cardiovascular system. The FT3/FT4 ratio can be used to evaluate the rate of T4-to-T3 conversion, reflecting the peripheral sensitivity of thyroid hormones. There is no study to investigate its relationship with death and cardiovascular disease (CVD) in the general population.MethodsThis retrospective cohort study involved 8,018 participants with measured thyroid function and no prior thyroid disease who participated in the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2012. Mortality status was determined by routine follow-up using the National Death Index through December 31, 2015.ResultsDuring a median of 87 months of follow-up, we observed 699 all-cause deaths, including 116 cardiovascular deaths. In multivariate adjusted models, higher free thyroxine (FT4) was linked to increased all-cause mortality (HR, 1.15 per SD; 95% CI, 1.09-1.22), cardiovascular mortality (HR, 1.18 per SD; 95% CI, 1.01-1.39), and CVD risk (HR, 1.17 per SD; 95% CI, 1.08-1.27). Higher free triiodothyronine (FT3) was linked to decreased all-cause mortality (HR 0.81 per SD; 95% CI, 0.70-0.93). Higher FT3/FT4 ratio was linked to decreased all-cause mortality (HR, 0.77 per SD; 95% CI, 0.69-0.85), cardiovascular mortality (HR, 0.79 per SD; 95% CI, 0.62-1.00), and CVD risk (HR, 0.82 per SD; 95% CI, 0.74-0.92). The FT3/FT4 ratio stratified findings were broadly consistent with the overall results.ConclusionsFT3, FT4, and the FT3/FT4 ratio were all independent predictors of all-cause death. FT4 and the FT3/FT4 ratio, but not FT3, were independent predictors of cardiovascular mortality and CVD risk. Along with FT3 and FT4, we should pay equal attention to the FT3/FT4 ratio in the general population.

Polypharmacy and Major Adverse Events in Atrial Fibrillation.

Patients with atrial fibrillation (AF) often receive multiple medications daily. The purpose of this study was to examine the prognostic implications of polypharmacy in patients with AF. This is a retrospective post hoc analysis of 1113 AF patients, enrolled in a randomized trial during an acute hospitalization (MISOAC-AF, NCT02941978). The presence of polypharmacy (use of >4 drugs daily) was assessed at hospital discharge. Regression analyses were performed to identify clinical predictors of polypharmacy and compare the outcomes of patients with or without confirmed polypharmacy. The coprimary outcomes were all-cause and cardiovascular (CV) mortality. Among patients with polypharmacy, the difference in the risk of mortality was also assessed per each added drug as a numeric variable. Polypharmacy was found in 36.9% of participants. Dyslipidemia, coronary artery disease, lower left ventricular ejection fraction, and higher glomerular filtration rates were independent predictors of polypharmacy. Polypharmacy was an independent predictor for all-cause death (adjusted hazard ratio [aHR]: 1.29, 95% confidence interval [CI]: 1.01-1.64) and CV death (aHR: 1.39, 95% CI: 1.05-1.84). Among patients with polypharmacy, each additional concomitant medication was independently associated with a 4% increased risk of all-cause mortality (aHR = 1.04, 95% CI: 1.00-1.08) and a 5% increased risk of CV mortality (aHR = 1.05, 95% CI: 1.00-1.10). Polypharmacy was common among patients with AF hospitalized in a tertiary hospital and was incrementally associated with higher rates of mortality.

Short-Term Prognostic Efficacy of mGPS and LCS in Patients With Acute Heart Failure.

AimSystemic inflammation plays an important role in the occurrence and development of acute heart failure. The modified Glasgow Prognostic Score (mGPS) and “lymphocyte C-reactive protein score” (LCS) are used to assess the inflammation levels in cancer patients. The purpose of this study was to assess the prognostic value of these two inflammation-related scoring systems in patients with acute heart failure.MethodsTwo hundred and fifty patients with acute heart failure were enrolled in this study. The mGPS and LCS scores were recorded after admission. All patients were divided into 2 groups: the death group and the survival group according to the 3-month follow-up results. The predictive values of mGPS and LCS were assessed using receiver-operating characteristic (ROC) analyses. Univariate and multivariate logistic analyses were used to evaluate the relationships between variables and endpoint.ResultsThe levels of mGPS and LCS in the death group were significantly higher than those in the survival group (P < 0.05). The areas under the ROC curve of the mGPS and LCS for predicting death were 0.695 (95%CI: 0.567~0.823) and 0.736 (95%CI: 0.616~0.856), respectively. Multivariate analysis demonstrated that both LCS, LVEF and serum direct bilirubin were independent predictors of all-cause death, excluding mGPS.ConclusionsCompared with mGPS, LCS is independently associated with short-term outcomes in patients with acute heart failure. LCS was a clinically promising and feasible prognostic scoring system for patients with acute heart failure.

Effects of chronic obstructive pulmonary disease on long-term prognosis of patients with coronary heart disease post-percutaneous coronary intervention.

BACKGROUNDChronic obstructive pulmonary disease (COPD) and cardiovascular diseases are often comorbid conditions, their co-occurrence yields worse outcomes than either condition alone. This study aimed to investigate COPD impacts on the five-year prognosis of patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI).METHODSPatients with CHD who underwent PCI in 2013 were recruited, and divided into COPD group and non-COPD group. Adverse events occurring among those groups were recorded during the five-year follow-up period after PCI, including all-cause death and cardiogenic death, myocardial infarction, repeated revascularization, as well as stroke and bleeding events. Major adverse cardiac and cerebral events were a composite of all-cause death, myocardial infarction, repeated revascularization and stroke.RESULTSA total of 9843 patients were consecutively enrolled, of which 229 patients (2.3%) had COPD. Compared to non-COPD patients, COPD patients were older, along with poorer estimated glomerular filtration rate and lower left ventricular ejection fraction. Five-year follow-up results showed that incidences of all-cause death and cardiogenic death, as well as major adverse cardiac and cerebral events, for the COPD group were significantly higher than for non-COPD group (10.5% vs. 3.9%, 7.4% vs. 2.3%, and 30.1% vs. 22.6%, respectively). COPD was found under multivariate Cox regression analysis, adjusted for confounding factors, to be an independent predictor of all-cause death [odds ratio (OR) = 1.76, 95% CI: 1.15–2.70, P = 0.009] and cardiogenic death (OR = 2.02, 95% CI: 1.21–3.39, P = 0.007). CONCLUSIONSCOPD is an independent predictive factor for clinical mortality, in which CHD patients with COPD are associated with worse prognosis than CHD patients with non-COPD.

Impact of recurrent acute heart failure hospitalizations on prognosis of heart failure patients

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Hospitalizations for acute heart failure (AHF) are significant events for heart failure (HF) patients (pts) with each hospitalization portending a poor prognosis. Our aim was to compare pts with recurrent AHF admissions to those without and to study the impact of recurrent admissions on overall mortality. Methods Single centre retrospective study that included all pts followed at the HF Clinic of the Cardiology Department that had at least one visit during 2018. All data since their initial follow-up on HF Clinic was considered. Recurrent admissions were defined as 2 or more admissions for AHF in the same year, during the follow-up. Results A total of 138 pts were included (83% male, mean age 61±11years). Dilated cardiomyopathy (65;47%) and ischemic cardiomyopathy (62;45%) were the most frequent aetiologies and most pts had HF with reduced ejection fraction (131;95%). Mean left ventricular ejection fraction (LVEF) was 26±9% and right ventricular dysfunction was present in 27% of the cases. The majority of patients was on NYHA class II (80, 58%). A total of 84 (61%) pts was medicated with inhibitors of the renin-angiotensin system (iRAS), 45 (33%) with angiotensin receptor-neprilysin inhibitor (ARNI), 127 (92%) with beta-blockers (BB) and 116 (84%) with mineralocorticoid receptor antagonists (MRA). Ninety-seven (70%) pts had a cardiac electronic device implanted (47 CRT, 50 ICD). During a median follow-up of 40 months (IQR 32-58), 41 (30%) pts had hospitalizations for AHF and 21 (15%) had recurrent admissions. The median time to the first hospitalization was 16 months (IQR 6-29). Pts with recurrent admissions had a similar comorbidity profile and HF aetiology in comparison to pts with one or none admissions. Considering baseline echocardiographic parameters on first visit, they had a higher mean E/E’ ratio (22±8 vs 14±6, p= .012) and pulmonary systolic artery pressures (52±20 vs 38±14 mmHg, p= .026). No differences were found in LVEF, left ventricular volumes, presence of right ventricular dysfunction or mitral regurgitation. They were less frequently medicated with iRAS or ARNI (81% vs 96%, p=.012) and BB (81% vs 94%, p= .043) and had a higher mean diuretic dosage (87±47 vs 63±43 mg). During the follow-up a total of 31 (22%) pts died, 14 (10%) for cardiovascular reasons. Pts with recurrent AHF admissions were more likely to die from any cause (log rank =.01). On a multivariate analysis, recurrent AHF hospitalizations were an independent predictor of all-cause death (HR 2.4, IC95% 1.1-5.2, p=.03). Conclusion Recurrent AHF hospitalizations are associated with a worse long-term outcome of HF pts. Efforts should be made for an earlier identification of these pts. A higher baseline pulmonary systolic artery pressure and mean E/E’ ratio may identify a higher risk group who benefits from a closer follow-up.

Pulmonary Congestion During Exercise Stress Echocardiography in Ischemic and Heart Failure Patients.

Lung ultrasound detects pulmonary congestion as B-lines at rest, and more frequently, during exercise stress echocardiography (ESE). We performed ESE plus lung ultrasound (4-site simplified scan) in 4392 subjects referred for semi-supine bike ESE in 24 certified centers in 9 countries. B-line score ranged from 0 (normal) to 40 (severely abnormal). Five different populations were evaluated: control subjects (n=103); chronic coronary syndromes (n=3701); heart failure with reduced ejection fraction (n=395); heart failure with preserved ejection fraction (n=70); ischemic mitral regurgitation ≥ moderate at rest (n=123). In a subset of 2478 patients, follow-up information was available. During ESE, B-lines increased in all study groups except controls. Age, hypertension, abnormal ejection fraction, peak wall motion score index, and abnormal heart rate reserve were associated with B-lines in multivariable regression analysis. Stress B lines (hazard ratio, 2.179 [95% CI, 1.015-4.680]; P=0.046) and ejection fraction <50% (hazard ratio, 2.942 [95% CI, 1.268-6.822]; P=0.012) were independent predictors of all-cause death (n=29 after a median follow-up of 29 months). B-lines identify the pulmonary congestion phenotype at rest, and more frequently, during ESE in ischemic and heart failure patients. Stress B-lines may help to refine risk stratification in these patients. URL: https://www. gov; Unique identifier: NCT03049995.

Incremental Prognostic Value of Left Ventricular Global Longitudinal Strain in Patients with Preserved Ejection Fraction Undergoing Transcatheter Aortic Valve Implantation

Evaluation of left ventricular global longitudinal strain (LVGLS) has allowed better characterization than left ventricular ejection fraction (LVEF) of subtle differences in left ventricular performance. The aim of this study was to determine whether LVGLS has prognostic value in patients with severe aortic stenosis and preserved LVEF undergoing transcatheter aortic valve implantation(TAVI). Among 412 consecutive patients who underwent TAVI, 344 patients (mean age, 78.9±5.0years; 161 men) with preserved LVEF (≥50%) at baseline were analyzed. Patients with low LVEF (<50%) were used as a comparison group in the survival analysis. The primary and secondary end points were all-cause death and a composite of cardiovascular death and heart failure hospitalization, respectively. The mean LVGLS and LVEF were -17.1±2.7% and 63±5%, respectively. Impaired LVGLS was defined as >-16%, which was the first LVGLS quartile (cutoff value, -16%). The estimated actuarial 5-year survival rate was 81.7±4.2% in the normal LVGLS group and 66.8±7.5% in the impaired LVGLS group (P=.005). In the multivariable analysis, impaired LVGLS was an independent predictor of all-cause death (adjusted hazard ratio, 2.26; 95% CI, 1.11-4.60) and the composite outcome (adjusted hazard ratio, 3.03; 95% CI, 1.45-6.33). Moreover, the impaired LVGLS group had a poor prognosis, similar to the impaired LVEF group (<50%). The addition of the absolute value of LVGLS to the clinical parameters and LVEF led to significant improvement in the prediction of all-cause mortality. In patients with severe aortic stenosis and preserved LVEF undergoing TAVI, subclinical LV dysfunction defined by impaired LVGLS is independently associated with poor clinical outcomes. LVGLS measurement provides incremental prognostic value above the established clinical and echocardiographic parameters.

Death and cardiovascular outcomes in end-stage renal failure patients on different modalities of dialysis

Cardiovascular morbidity and mortality in end-stage renal failure (ESRF) patients are high. We examined the incidence and predictors of death and acute myocardial infarction (AMI) in ESRF patients on different modalities of dialysis. Data were obtained from a population-based database (National Registry Disease Offices) in Singapore. The study cohort comprised all adult patients initiated on dialysis between 2007 and 2012 who were closely followed for the development of death and AMI until September 2014. Cox regression methods were used to identify predictors of death and AMI. Of 5,309 patients, 4,449 were on haemodialysis and 860 on peritoneal dialysis (PD). Mean age of the cohort was 61 (±13) years (44% women), of Chinese (67%), Malay (25%) and Indian (7%) ethnicities. By September 2014, the incidence of all-cause death was 34%; close to a third of the patients died from a cardiovascular cause. Age >60 years and the presence of ischaemic heart disease, diabetes, stroke, peripheral vascular disease and PD were identified as independent predictors of all-cause death. PD patients had lower odds of survival compared to patients on haemodialysis (hazard ratio 1.51, 95% confidence interval 1.35-1.70, P<0.0001). Predictors of AMI in this cohort were older age (>60 years) and the presence of ischaemic heart disease, diabetes, stroke, peripheral vascular disease and current/ex-smokers. There were no significant differences in the incidence of AMI between patients on PD and haemodialysis. The short-term incidence of death and AMI remains high in Singapore. Future studies should investigate the benefits of a tighter control of cardiovascular risk factors among ESRF patients on dialysis.

Soluble urokinase plasminogen activator receptor and functionally relevant coronary artery disease: a prospective cohort study

Background Soluble urokinase plasminogen activator receptor (suPAR) is an emerging biomarker associated with anatomical CAD burden and cardiovascular outcomes including myocardial infarction (MI) and death. We aimed to validate previous findings of the prognostic value of suPAR and to evaluate its diagnostic potential for functional relevant CAD (fCAD). Methods Consecutive patients with suspected fCAD were enrolled. Adjudication of fCAD was performed blinded to suPAR concentrations by myocardial perfusion single-photon emission tomography (MPI-SPECT) and coronary angiography. Prognostic outcome measures included all-cause death, cardiovascular death, and incident MI during 2-year follow-up. Results Among consecutive 968 patients, suPAR concentrations were higher in patients with fCAD compared to those without (3.45 vs. 3.20 ng/mL, p = 0.007), but did not provide acceptable diagnostic accuracy (area under the curve [AUC]: 0.56, 95%CI 0.52–0.60). SuPAR correlated with high-sensitivity cardiac-troponin T (Spearman’s rho (ρ) 0.393, p < 0.001), NT-proBNP (ρ = 0.327, p < 0.001), age (ρ = 0.364, p < 0.001) and very weakly with coronary atherosclerosis (ρ = 0.123, p < 0.001). Prognostic discrimination of suPAR was moderate for cardiovascular death (AUC = 0.72, 95%CI 0.62–0.81) and all-cause death (AUC = 0.72, 95%CI 0.65–0.79) at 2-years. SuPAR remained a significant predictor for all-cause death in multivariable Cox regression (HR = 1.96, p = 0.001). Conclusions SuPAR was an independent predictor of all-cause death, without diagnostic utility for fCAD. Clinical trial registration NCT01838148
