Single Centre Experience and Outcome of Primary Percutaneous Coronary Intervention for Patients with ST-Segment-Elevation Myocardial Infarction

Background: Primary percutaneous coronary intervention is an emergent coronary angiography and mechanical reperfusion of the infarct-related artery performed in patients with ST-segment elevation myocardial infarction. The present study aimed to determine the outcomes of primary percutaneous coronary intervention in a tertiary care cardiac centre. Aims: The present study carried out with the aim to determine the outcomes of primary percutaneous coronary intervention in a tertiary care cardiac centre. Methods: We evaluated 548 patients presented treated for ST-segment elevation myocardial infarction with primary percutaneous coronary intervention at Sri Venkateswara Institute of Medical Sciences, Tirupati, India from January 2011 to December 2012. Results: Total 548 patients were included in this study. Mean age of patients was 54.5 ± 11.5 years. Cardiogenic shock, complete heart block and ventricular tachycardia / ventricular fibrillation was encountered in 31 (5.7%), 40 (7.3%) and 49 (8.9%) patients respectively at hospital admission. The average door to balloon time was 62.5 ± 15.0 minutes. Thrombus aspiration was performed in 159 (29.0%) patients during the index procedure. During hospital stay, in-hospital mortality was 20 (3.6%) out of which 15 (2.7%) patients died from cardiac cause. Target vessel revascularization, major bleeding and minor bleeding observed in 5 (0.9%), 5 (0.9%) and 11 (2.0%) cases respectively. Result of this six-month outcome of the studied showed 5 (0.9%) deaths and 5 (0.9%) incidence of target vessel revascularization. Conclusions: Our data suggest that primary percutaneous coronary intervention for ST-segment elevation myocardial infarction can be safely performed in a regional institution with acceptable door to balloon time and low major adverse cardiac event rates.
