Predictors of Favourable Response to Cardiac Resynchronization Therapy in Patients with Heart Failure with Reduced Ejection Fraction: A Narrative Review

Cardiac resynchronization therapy (CRT) is an effective treatment for selected patients with heart failure with reduced ejection fraction, but 30–40% of recipients do not respond. This narrative review summarizes predictors of a favourable response to CRT. Typical left bundle branch block (LBBB) and a QRS duration ≥ 15...

Myocardial Work Index Dispersion as a Potential Predictor of Ventricular Arrhythmias in Patients with Heart Failure with Reduced Ejection Fraction

Background: Mechanical dispersion of left ventricular contraction reflects electromechanical heterogeneity and may contribute to arrhythmogenesis. We evaluated whether myocardial work dispersion is associated with ventricular arrhythmia (VA) risk in patients with heart failure with reduced ejection fraction (HFrEF). Me...

Etiology-Related Differences in Left Ventricular Remodeling and Left Atrial Function in Patients with Heart Failure and Reduced Ejection Fraction Referred for ICD/CRT Implantation

Background: Heart failure with reduced ejection fraction (HFrEF) may be caused by various factors. The etiology of HFrEF may influence prognosis and further management. Objectives: In this study we aimed to assess differences between ischemic and non-ischemic etiology in the context of clinical features, hemodynamic ev...
