Objective: The index of myocardial performance (IMP) is a global cardiac function index with prognostic utility in patients with myocardial infarction and dilated cardiomyopathy but is preload dependent. We hypothesized that a volume overload lesion prolonging LV ejection time (LVET) may reduce IMP despite LV dysfunction (LVD).
Methods: The study groups consisted of 35 normals, 26 with LV dysfunction, and 60 with aortic regurgitation (AR): 40 with ejection fraction (EF) >50% (AR+Normal EF) and 20 with ejection fraction > or = 50% (AR+Reduced EF).
