Diagnostic accuracy of artificial-intelligence-based electrocardiogram algorithm to estimate heart failure with reduced ejection fraction: a systematic review and meta-analysis

Curr. probl. cardiol; 50 (4), 2025
INTRODUCTION: AI-based ECG has shown good accuracy in diagnosing heart failure. However, due to the heterogeneity of studies regarding cutoff points, its precision for specifically detecting heart failure with left ventricle reduced ejection fraction (LVEF <40 %) is not yet well established. What is the ...

Cardiopulmonary exercise testing in patients with left bundle branch block and preserved ejection fraction

BACKGROUND: Left bundle branch block (LBBB) has prognostic significance in patients with congestive heart failure. However, its influence is not well established in patients with preserved systolic ventricular function. OBJECTIVE: To evaluate the implications of LBBB presence in the cardiovascular perfor...
