ABSTRACT
Objective: To determine the frequency of sustained ventricular arrhythmias in Non-ST segment elevation myocardial infarction (NSTEMI) patients.
Study Design: Descriptive case series study.
Place and Duration of Study: This study was conducted at the Department of Cardiology, Chaudhry Pervaiz Ellahi Institute of Cardiology, Multan from 10-Aug-2018 to 9-Feb-2019.
Materials and Methods: A total of 170 patients who presented in department of cardiac emergency with Non ST segment myocardial infarction were enrolled in the study. Each Patient with NSTEMI was monitored centrally on cardiac monitor for 3 days and documented sustained ventricular arrhythmias on ECG were further interpreted by senior consultant cardiologist. SPSS version 23 was used for data analysis.
Results: Mean age of patients was 50.66±6.95 years. There were more male patients as compared to female patients i.e. n=140 (82.4%) male patients and n=30 (17.6%) female. There were n=59 (34.7%) patients who were having diabetes mellitus. Similarly n=75 (44.1%) patients who were having hypertension. n=58 (34.1%) patients who were having history of smoking and n=15 (8.8%) patients were having hypercholesterolemia. There were n=16 (9.4%) patients who were having positive family history of coronary artery disease (CAD). Cardio-version was done in n=11 (6.5%) patients of non-STE myocardial infarction. Sustained ventricular arrhythmias (VA) occurred in n=12 (7.1%) patients of non-STEMI.
Conclusion: The incidence of Sustained ventricular arrhythmias in patients of non-ST elevation myocardial infarction (NSTEMI) is 7.1%. 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.
Key Words: Non-ST elevation myocardial infarction, ventricular arrhythmia, Cardiac monitoring.
