Ventricular mechanical asynchrony in patients with different degrees of systolic dysfunction: results from AVE Registry by the Italian Society of Cardiovascular Echography (SIEC).

Objective: The aim of the study was to compare the prevalence of interventricular and intraventricular asynchrony in patients with different degrees of left ventricular (LV) dysfunction. Methods: We enrolled 182 patients (male 79%, mean age 64 ± 11 years) with LV ejection fraction (EF) 102 msec) did not differ between groups either (29.9% vs. 35.9%; P = 0.39). Conclusions: The prevalence of intraventricular asynchrony is independent of the LV systolic dysfunction severity. This could indicate the potential role of cardiac resynchronization therapy in patients with mild-moderate systolic dysfunction. (ECHOCARDIOGRAPHY 2010;27:110-116)
