Department of Cardiology, Karachi Institute of Heart Diseases, Karachi.



To determine the outcome of Primary Precutaneous Coronary Intervention (PCI) in our setup and compare the results with the west.


This study was conducted at a tertiary care teaching Hospital (National Institute of Cardiovascular Diseases Karachi, Pakistan) during January 1st, 2008 to December 31st, 2008. A total of 113 patients were enrolled who came with STEMI and agreed to go for Primary PCI. We excluded the patients who had history of Thrombolytic therapy within 24 hours, presented with Non ST-elevation Myocardial Infarction (NSTEMI) and coronary angiogram revealed significant left Main or equivalent disease. All Patients received Aspirin, Clopidogrel and Platelet Glycoprotein IIB IIIA Inhibitor. After Primary PCI patients were planned to follow at one month, 3 months and 6 months. Primary end point was to document death, MI, CABG and rehospitalization.


Out of 113 cases, 102 (90.3%) were male and 11 (9.7%) were female, Mean age was 51.2 +/- 11.7 years, 54 (47.8%) patients had Hypertension, 28 (24.8%) were Diabetics and 44 (38.9%) were Smokers. Immediate success was achieved in 111 (98.2%) cases. In hospital mortality was 5.3% (3.5% in cardiogenic shock, 1.7% in non-shock patients). Mean Door to Balloon time remained 98.4 minutes. Twelve patients were lost to follow up. Therefore at 6 months, out of 101 patients, 8 (7.9%) died, 5 (4.9%) underwent Coronary Artery Bypass Graft (CABG) surgery and 5 (4.9 %) had been re-hospitalized either for recurrent myocardial infarction or heart failure.


Optimal results of primary percutaneous coronary intervention can be achieved for acute STEMI in a developing country at a tertiary care public sector hospital. The results are comparable and nearly similar to the west.
