Abstract

Introduction: The clinical characteristics and outcome of patients hospitalized with heart failure vary according to ethnicities.

Background: Limited epidemiologic data are available about the clinical characteristics and outcome of heart failure (HF) patients among non-Caucasian populations.

Methods: Between 1 January 1991 and 31 December 2010; 41 453 consecutive patients were hospitalized at Hamad General Hospital, Doha, Qatar for cardiac reasons. Patients were into two groups; hospitalized with HF (n = 7069) and hospitalized for non-HF (no-HF). Among HF patients Sub-analysis was made according to ethnicity; Middle-eastern Arabs (MEA) (n = 5227) versus South Asian (SA) (n = 1289) patients.

Results: HF patients were older and more likely to be female when compared to non-HF patients. HF patients were also more likely to have diabetes mellitus (DM), hypertension (HTN), atrial fibrillation (AF) and renal impairment when compared to non-HF patients. SA HF patients younger and less likely to have DM, HTN and AF when compared to MEA patients. Over the 20-years period there was decrease in in-hospital mortality and stroke rates regardless of ethnicity (death; 8.3% to 4.8%, stroke; 0.8% to 0.1%; all P = 0.001).

Conclusion: HF patients in the Middle East present at relatively younger age regardless of ethnicity. In-hospital mortality and stroke rates decreased significantly over the 20-years.
