Procedure indications and outcome of percutaneous coronary interventions in a tertiary care hospital.

Objective: To determine clinical indications and one month outcome of Percutaneous Coronary Interventions (PCI) in a tertiary care centre.

Methods: We prospectively conducted a descriptive study on 259 symptomatic coronary artery disease patients, who underwent primary, rescue or elective PCI with stent deployment at the Tabba Heart Institute, from May 2005 to September 2006. The primary objective of the study was to identify--stable angina, unstable angina, Non-ST elevation myocardial infarction (NSTEMI), ST elevation myocardial infarction (STEMI), congestive heart failure (CHF) and cardiogenic shock) and thirty days outcome of PCI in terms of mortality, peri-procedural myocardial infarction, re-infarction and stent thrombosis. This was done according to the standard guidelines of Canadian Cardiovascular Society and New York Heart Association classification. The patients were followed for one month and complications were noted.

Results: The mean age of sample was 54.9 +/- 10.6 years. The indications were stable angina (32.4%), unstable angina (13.9%), NSTEMI (18.9%), STEMI (35.1%), CHF (5.4%) and cardiogenic shock (1.5%). The outcome was mortality (2.7%), peri-procedure MI (0.4%), re-infarction (3.08%), cardiogenic shock (1.5%) and stent thrombosis (4.3%).

Conclusion: Our clinical indications and outcome are comparable with international findings. Stable angina was a major indication and stent thrombosis was the major complication observed, particularly after primary percutaneous intervention for STEMI.
