Risk and Protective Factors of Poor Clinical Outcomes in Heart Failure with Improved Ejection Fraction Population: A Systematic Review and Meta-Analysis.

Aims: Heart failure with improved ejection fraction (HFimpEF) patients could still develop adverse outcomes despite EF improvement. This study evaluates the risk and protective factors of poor clinical outcomes in HFimpEF patients.

Methods: Systematic searching was done to include studies that evaluate the risks of developing poor outcomes in HFimpEF patients.

Risks factors of adverse clinical outcomes in asymptomatic mitral regurgitation patients with preserved ejection fraction: a systematic review and meta-analysis.

Introduction And Objective: Indication for mitral valve (MV) surgery in asymptomatic mitral regurgitation (MR) patients with preserved ejection fraction (EF) remains unclear. This study aims to identify risk factors of adverse clinical outcomes in asymptomatic MR patients with preserved EF for early indication of MV surgery.

Methods: 3 databases were systematically searched to include studies with asymptomatic MR patients with preserved EF.
