title: Outcome of patients with ST segment elevation myocardial infarction (STEMI) following percutaneous transluminal coronary angioplasty: a retrospective study.
abstract: OBJECTIVE
  To study the characteristics and long term outcome of patients who had segment elevation myocardial infarction (STEMI) and treated with PTCA in a fee levying hospital in Sri Lanka.
  
  
  METHODS
  A retrospective study was conducted among patients diagnosed with STEMI and treated with PTCA in a fee levying private hospital in Colombo from 1st January 2009 to 1st November 2012. Details of patients were obtained from medical records and the survival status, cause of death and date of death where relevant, were obtained from records, patients or close relatives.
  
  
  RESULTS
  197 patients (153 men; 77.7%) were included. More than 50% had a history of diabetes, dyslipidaemia or hypertension. The three year survival was 82.7% (95% CI: 77.9%-90.5%). Based on the Cox's Proportional Hazards model, site of arterial occlusion (proximal vs distal segment of left anterior descending artery [LAD] was significantly associated with mortality due to all causes [HR 10.98; 95% CI: 1.09-110.20]. Low ejection fraction, not on regular medication and delay of more than 3 hours between onset to door time were associated with death due to cardiovascular causes in patients whose right coronary artery or left circumflex artery was the culprit artery.
  
  
  CONCLUSIONS
  The three year survival of patients with STEMI and who had PTCA was 83%. Patients with proximal LAD occlusion were 11 times more likely to die within 3 years of PTCA as compared to those who had a distal LAD occlusion.
