Patients with HFpEF and HFrEF have different clinical characteristics but similar prognosis: a retrospective cohort study

311 adult patients admitted with heart failure (164 with HFpEF, 147 with HFrEF) to the University of Gondar Referral Hospital, Ethiopia. Mean age 53.58 years, 69.77% women. Key inclusion: age ≥18, diagnosis of HF based on Framingham criteria. Key exclusion: concomitant infection, no echocardiography record, NYHA Class I-II, missing laboratory records.

Heart failure with preserved ejection fraction (HFpEF, LVEF ≥ 50%)

Heart failure with reduced ejection fraction (HFrEF, LVEF < 50%)
