FREQUENCY OF SUSTAINED VENTRICULAR ARRHYTHMIAS IN PATIENTS WITH NON-ST SEGMENT ELEVATION MYOCARDIAL INFARCTION AT A TERTIARY CARE HOSPITAL

Abstract

Objectives: To determine the frequency of sustained ventricular arrhythmias in Non-ST segment elevation myocardial infarction (NSTEMI) patients. Methodology: This is a Cross sectional study was done at Chaudhry Pervaiz Elahi Institute of Cardiology, Multan Pakistan from 10th August 2018 to 9th February 2019. We included 170 patients fulfilling the inclusion criteria with diagnosis of NSTEMI presented in department of cardiac emergency were selected. Informed consent was taken. The data was collected on prepared proforma. Results: In our study          mean age of patients was 50.90+7.25 years. There were 139 (81.76%) male patients and 31 (18.24%) female patients. There were 58 (34.12%) patients who were having diabetes mellitus, 68 (40.0%) patient’s having hypertension, 71 (41.76%) patients were smokers, 15 (8.82%) patients were having hypercholesterolemia, and 18 (10.59%) patients who were having positive family history of coronary artery disease (CAD). Sustained ventricular arrhythmias (VA) occurred in 9 (5.29%) patients of non-STEMI. Conclusion: The incidence of Sustained ventricular arrhythmias in patients of non-ST elevation myocardial infarction (NSTEMI) is 5.29%. The occurrence of such events remains difficult to predict. Cardiac monitoring should be done in all patients to monitor occurrence of such Sustained ventricular arrhythmias in these patients.
