Comparative analysis of risk factors for heart failure with preserved vs reduced ejection fraction in patients with heart failure

ABSTRACT

Aims: The prevalence of heart failure with preserved ejection fraction [HFpEF] has increased in the past two decades. Although it has been demonstrated that left ventricular [LV] diastolic and vascular functional abnormalities are generally observed in HFpEF, it remains to be clinically elucidated how an asymptomatic stage progresses to symptomatic HFpEF. We aimed to identify risk factors associated with incident HFpEF and to compare it with systolic heart failure [SHF]
