Abstract

Background: Chronic heart failure (CHF) impairs the heart’s pumping ability due to structural or functional issues. Global Longitudinal Strain (GLS) is a precise method for assessing left ventricular function, while NT-proBNP is used to diagnose heart failure and predict outcomes. This study examines the relationship between GLS and NT-proBNP as predictors of major cardiovascular events in CHF patients with reduced ejection fraction. Methods: Chronic heart failure patients with LVEF ≤49% were observed in a cohort study. After echocardiography and NT-proBNP blood sampling, they were followed for 3 months to monitor rehospitalization and/or mortality. Baseline characteristics included demographic, clinical, comorbidity, laboratory, and echocardiographic data. GLS and NT-proBNP cutoff values were determined via ROC curves, and survival analysis was conducted using Kaplan-Meier curves and Cox Regression in SPSS 26.0. Results: A total of 65 samples were enrolled with no drop-outs. The optimal GLS cutoff was -7,5% (AUC 0,763, p=0,017) with 62,5% sensitivity and 86% specificity. NT-proBNP’s cutoff was 689 pg/mL (AUC 0,556; p=0,611) with 50% sensitivity and 87,7% specificity. Survival analysis showed lower survival rates in patients with GLS ≥-7,5% (66,7% vs. 92,5%; p=0,022) and NT-proBNP ≥689 (63,6% vs. 92,6%; p=0,012). However, neither GLS ≥-7,5% nor NT-proBNP ≥689 pg/mL were significant independent predictors of major cardiovascular events within 3 months. Higher LAVI (≥41 ml/m2) was found to be a significant independent predictor, associated with GLS ≥-7,5 (r -0,329; p=0,007), high NT-proBNP (r 0,632; p=0,03), EF (r -0,610; p<0,001), E/e’ (r -0,32; p=0,014), and medial E (r 0,28; p=0,024).
