ASSOCIATION OF THROMBOLYSIS IN MYOCARDIAL INFARCTION (TIMI) RISK SCORE WITH EXTENT OF CORONARY ARTERY DISEASE IN PATIENTS WITH UNSTABLE ANGINA AND NSTEMI
Abstract
Objective: To evaluate the correlation between thrombolytic in Myocardial Infarction risk score with the severity of coronary lesions found by coronary angiography during hospitalization in patients with non-ST elevation Acute coronary syndrome. Study Design: Cross sectional study. Place and Duration of Study: Adult Cardiology department, Armed Forces Institute of Cardiology & National Institute of Heart Diseases, Rawalpindi from Jul to Dec 2018. Methodology: Patients who had chest pain suggestive of angina or anginal equivalent symptoms and diagnosis of Acute Coronary Syndrome (ACS) were included in the study. Patients with Acute Coronary Syndrome were risk stratified with Thrombolysis In Myocardial Infarction risk scores and were further evaluated with coronary angiograms to assess the extent of coronary artery disease. Results: Total 115 patients were recruited in the study with mean age 57.08 ± 10.2 years. There were 87 (75.7%) male patients while 28 (24.3%) female patients. The most common co-morbidity was hypertension 66 (57.4%) followed by diabetes mellitus 39 (33.9%) and smoking 25 (21.7%). 71 (61.7%) patients had one angina episode in the last 2 hours while 34 patients had two angina episodes in the last 2 hours. Cardiac biomarkers were raised in 36 (31.3%) patients. 60 (52.2%) used aspirin in the last 7 days. Chi-square test was applied between Thrombolysis In Myocardial Infarction Score and Coronaries lesions, which showed statistically significant results (p<0.001). Conclusion: Our study demonstrates that among patients presenting with Non-STE Acute coronary syndrome i.e. unstable angina /NSTEMI who are referred for coronary angiography, clinical risk stratification according......
