Abstract

Heart failure with recovered left ventricular ejection fraction (HFrecEF) is defined as heart failure  previously documented that LV ejection fraction (LVEF) was less than 40% and subsequent follow-up study after treatment showed more than 10% improvement of LVEF and greater than 40%. The recovery of LVEF depends on the ethiology of LV systolic dysfunction that causes heart failure with reduced LV ejection fraction (HFrEF) and also the treatment of heart failure. Heart failure with less severity or full recovery of myocardial pathology has better recovery of LVEF such as in tachycardia induced cardiomyopathy, Takotsubo cardiomyopathy, and hyperthyroidism. However, the recovery of LVEF reflects adaptation to the new balance of myocardial function rather than fully remission of pathology of the disease. The recommendation for treatment of HFrecEF is still based on the treatment guideline for HFrEF, even in patient with normal functional capacity and normal LVEF. Termination of HFrecEF treatments may be considered in patient with completely correctable causes of heart failure such as peripartum cardiomyopathy with normal LVEF.
