title: Prevalence and outcome of Middle-eastern Arab and South Asian patients hospitalized with heart failure: insight from a 20-year registry in a Middle-eastern country (1991-2010).
abstract: BACKGROUND
  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).
  
  
  CONCLUSIONS
  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.
