Abstract Background Novel echocardiographic software allows for layer-specific evaluation of myocardial deformation by 2-dimensional speckle tracking echocardiography. Endocardial, epicardial- and whole wall global longitudinal strain (GLS) may be superior to conventional echocardiographic parameters in predicting all-cause mortality in patients with heart failure with reduced ejection fraction (HFrEF). Purpose The purpose of this study was to investigate the prognostic value of endocardial-, epicardial- and whole wall GLS in patients with HFrEF in relation to all-cause mortality. Methods We included and analyzed transthoracic echocardiographic examinations from 1,015 patients with HFrEF. The echocardiographic images were analyzed, and conventional and novel echocardiographic parameters were obtained. A p value in a 2-sided test <0.05 was considered statistically significant. Cox proportional hazards regression models were constructed, and both univariable and multivariable hazard ratios (HRs) were calculated. Results During a median follow-up time of 40 months, 171 patients (16.8%) died. A lower endocardial (HR 1.17; 95% CI (1.11–1.23), per 1% decrease, p<0.001), epicardial (HR 1.20; 95% CI (1.13–1.27), per 1% decrease, p<0.001), and whole wall (HR 1.20; 95% CI (1.14–1.27), per 1% decrease, p<0.001) GLS were all associated with higher risk of death (Figure 1). Both endocardial (HR 1.12; 95% CI (1.01–1.23), p=0.027), epicardial (HR 1.13; 95% CI (1.01–1.26), p=0.040) and whole wall (HR 1.13; 95% CI (1.01–1.27), p=0.030) GLS remained independent predictors of mortality in the multivariable models after adjusting for significant clinical parameters (age, sex, total cholesterol, mean arterial pressure, heart rate, ischemic cardiomyopathy, percutaneous transluminal coronary angioplasty and diabetes) and conventional echocardiographic parameters (left ventricular (LV) ejection fraction, LV mass index, left atrial volume index, deceleration time, E/e', E-velocity, E/A ratio and tricuspid annular plane systolic excursion). No other echocardiographic parameters remained an independent predictors after adjusting. Furthermore, endocardial, epicardial and whole wall GLS had the highest C-statistics of all the echocardiographic parameters. Conclusion Endocardial, epicardial and whole wall GLS are independent predictors of all-cause mortality in patients with HFrEF. Furthermore, endocardial, epicardial and whole wall GLS were superior prognosticators of all-cause mortality compared with all other echocardiographic parameters.

Objective. The prognostic value of N-terminal procerebral natriuretic peptide (NT-proBNP) in patients with heart failure (HF) is well established. In contrast, its role as an early predictor of mortality in patients hospitalized for heart failure with preserved ejection fraction (HF-EF) and heart failure with reduced ejection fraction (HF-EF) is less well documented. Therefore, the objective of this study is to evaluate the usefulness and prognostic value of plasma NT-proBNP in these patients. Method. This retrospective observational study included 620 patients admitted for acute heart failure, classified into 3 groups according to their left ventricular ejection fraction (LVEF): HF-EF (LVEF ≥ 50%), HF-mEF (heart failure with ejection fraction mean) (LVEF 35-49%) and HF-rEF (LVEF <40%), whose plasma levels of NT-proBNP and clinical data were determined at hospital admission. Univariate and multivariate logistic regression was used to perform prognostic values of NT-proBNP levels for 3.4 years of all-cause mortality in each group. Results: The mean plasma levels of NT-proBNP in patients with HF-cEF (35%) and borderline HF-cEF (43%) was 1001-5000 pg / ml; patients with HF-rEF were similarly distributed between the groups 1001-5000pg / ml (30%), 5001-15000pg / ml (31%) and> 15001pg / ml (30.6%). The mortality rate increased significantly in patients with NT-proBNP concentrations > 15001 pg / ml (40%) and decreased with NT-proBNP levels <250 pg / ml (4%), compared to the other NT-proBNP groups. The mortality rate increased proportionally to elevated baseline NT-proBNP, regardless of LVEF. Conclusion. In patients hospitalized for an acute decompensated event with HF-cEF (LVEF ≥50%) and HF-mEF (LVEF 35-49%), plasma levels of NT-proBNP are a useful tool to predict early mortality, as for HF -FEr (LVEF <40%).
