title: Assessment of the management of acute myocardial infarction patients and their outcomes at the Nairobi Hospital from January 2007 to June 2009.
abstract: BACKGROUND
  The demographics, clinical characteristics and management of patients presenting at the Nairobi Hospital with acute myocardial infarction have not been documented in the past. There is a paucity of studies on this subject in this region.
  
  
  METHODS
  A retrospective, hospital-based study was carried out, examining data of patients presenting at Nairobi Hospital with acute myocardial infarction between January 2007 and June 2009. The data collected were patient demographics, coronary artery disease (CAD) risk factors, clinical presentation, GRACE score risk stratification, coronary anatomical findings on angiography, interventions and outcomes during hospitalisation.
  
  
  RESULTS
  Sixty-four patients were recruited (mean age 56.7 years). The CAD risk-factor profile included systemic hypertension in 71.9% of patients, age over 55 or 65 years in men and women, respectively in 42.2%, 35.9% of subjects were smokers, low high-density lipoprotein cholesterol levels in 25%, diabetes mellitus in 25%, family history of premature coronary artery disease in 8%, prior acute coronary syndrome in 18.8%, ST-segment elevation myocardial infarction (STEMI) in 60.9% and non-ST-segment elevation myocardial infarction (NSTEMI) in 39.1% of patients. In the STEMI arm, 79.5% of patients underwent thrombolysis, 17.9% had rescue percutaneous coronary intervention (PCI) and 2.6% had no reperfusion therapy. Medical management was carried out in 29% of the patients, 19.1% had a coronary artery bypass graft and 40.4% had PCI. The mean duration of hospitalisation was 6.69 days. The in-hospital mortality rate was 9.4% and mean in-hospital probability of death according to the GRACE risk score was 16.05%. Discharge medication was a β-blocker in 84.5% of patients, an ACE inhibitor or angiotensin receptor blocker in 48.3%, low-dose aspirin in 96.6%, clopidogrel in 96.6% and statins in 93.1%.
  
  
  CONCLUSIONS
  The risk-factor assessment in our population, albeit small, was in keeping with the traditional risk factors for coronary artery disease. There is, however, room for improvement in reconciling the gap between actual and recommended patient care.
