Abstract :

Introduction: Acute coronary syndrome (ACS) includes both ST elevation myocardial infarction (STEMI) and unstable angina & non–ST elevation MI (USA/NSTEMI). In western countries, USA/NSTEMI is the most common cause of ACS (60–70%), but in India, it contributes only 30–40% of ACS. Most of NSTEMI patients are likely to have multi–vessel disease. Our aim of the study is to evaluate the angiographic profile of coronary artery disease in USA/NSTEMI patients. Materials & Methods: This is a single centered cross–sectional study – USA/NSTEMI ACS patients admitted to our hospital, who underwent diagnostic coronary angiogram (CAG) from the period of November 2017 to May 2018. Results: Total of 182 USA/NSTEMI ACS patients has undergone CAG. Mean age of presentation was 53 ± 9.18. Out of 182 patients, 69% were male, 36.8% were diabetic, and 38.5% were systemic hypertension. Angiographic profile of CAD in our study was single vessel disease (SVD) was seen in 39%, double vessel disease (DVD) in 24.1%, triple vessel disease (TVD) in 18.1, left main disease (LM) in 11.5, minimal CAD in 10.9%, normal epicardial coronaries were seen in 8.2%. In our study, those patients with diabetes, elderly & LV dysfunction were more likely to have multi–vessel disease. Conclusion: In our study angiographic profile of coronary artery disease in USA/NSTEMI was comparable to TACTIS –TIMI–18 trial. Diabetes, elderly and LV dysfunction are important predictors of multi–vessel disease in our study which will be useful prognostic marker for further risk stratification in USA/NSTEMI.
