Left Ventricular Longitudinal Myocardial Function of Heart Failure Patients With Transition From Reduced to Preserved Ejection Fraction and of Those With Preserved Ejection Fraction

Background: Left ventricular (LV) longitudinal myocardial function is associated with the outcomes of heart failure (HF) patients. HF with improved ejection fraction (EF), known as HFimpEF, which is defined as current LVEF >40% but any previously documented LVEF ≤40%, has favorable outcomes compa...

Description
Summary:Background: Left ventricular (LV) longitudinal myocardial function is associated with the outcomes of heart failure (HF) patients. HF with improved ejection fraction (EF), known as HFimpEF, which is defined as current LVEF >40% but any previously documented LVEF ≤40%, has favorable outcomes compared with HF with preserved EF (HFpEF). However, LV longitudinal myocardial function in patients with previously reduced LVEF (15.0% had fewer cardiovascular events than those without (log-rank P=0.014) among all the patients.Conclusions: LV longitudinal myocardial dysfunction was more frequently observed in patients with HFpEF than in those with HFnorEF, even when LVEF was similar, and was independently associated with cardiovascular events for HF patients with current LVEF ≥50%.
