Abstract:BackgroundHeart failure with preserved ejection fraction (HFpEF) is a group of diseases classified by left ventricular (LV) EF, a measure of pump function. However, LVEF does not reflect LV contractility. Previous studies have shown that tissue Doppler‐derived LV isovolumic contraction velocity (IVCv) correlates well with the LV peak dP/dt, an index of LV contractility. We explored whether LV IVCv is associated with 1‐year post‐discharge outcomes in HFpEF.MethodsWe enrolled 113 patients (median age, 86 years, … Show more
