Abstract

Using speckle-tracking imaging (STI), the aims of this study were to assess dyssynchrony and quantify the myocardial energy wasted by contractility in delayed segments by determining the longitudinal strain delay index (LSDi) in patients with heart failure with preserved ejection fraction (HFpEF).
