Myocardial constructive work and cardiac mortality in resynchronization therapy candidates

Recent studies have shown that myocardial constructive work (CW) assessed by pressure-strain loops (PSLs) is an independent predictor of a volumetric response to cardiac resynchronization therapy (CRT). The aim of this study was to evaluate the role of CW in predicting the cardiac outcome of heart failure patients undergoing CRT. This is a retrospective study including 166 CRT candidates (ejection fraction [EF] ≤35%, QRS duration ≥120...
