Background & ObjectiveAcute coronary syndrome (ACS) can be divided into subgroups of ST-segment elevation myocardial infarction (STEMI), Non-ST-segment elevation myocardial infarction (NSTEMI), and unstable angina (USA). Patients diagnosed with NSTEMI are either treated conservatively or early invasive strategy is adopted. In NSTEMI it is believed that either one or more vessel is transiently occluded or that the blood flow is critically reduced in a patent vessel i.e. subtotal occlusion. This study was conducted to find the angiographic characteristics of NSTEMI patients undergoing coronary angiography.MethodsThis study was conducted in Department of Cardiology, Lady Reading Hospital Peshawar. It was Cross Sectional Study. Data was collected from 8th November 2022 to 8th May 2023. Consecutive non-probability sampling technique was used to collect data from the patients.ResultsTotal of 300 patients were studied. The mean age was 56.95 years ±1.176 standard deviation. Male patients were 201 (67%) and remaining were female. It was found that 51(17%) of total NSTEMI patients were having totally obstructed coronary artery (OCA) in one or more coronary arteries. In NSTEMI, non-obstructive CAD (<50%) were found in 81 (27%) of patients whereas 219 (73%) were having significant CAD. It was found that 40% were having single vessel CAD, 32% were having double vessel CAD and 28% were having triple vessel CAD. TVCAD was present significantly higher in advance age, Diabetes mellitus, hyperlipidemia and family history of CAD.ConclusionPatients having NSTEMI are usually having multiple risk factors and having usually severe and multivessel CAD.Copyright: © Pakistan Journal of Medical Sciences.
