Predictors and Prognostic Factors of Heart Failure with Improved Ejection Fraction

HFrEF patients without a history of alcohol consumption, non-NYHA class III-IV, without dilated cardiomyopathy, concomitant hypertension, <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mi>β</mml:mi></mml:math> -blockers use, and lower uric acid were more likely to have LVEF improvement. Although the prognosis of HFimpEF patients was better than that of HFrEF patients, older age, NYHA class III-IV, concomitant valvular heart disease, and higher creatinine were still risk factors for cardiovascular events in HFimpEF patients.
