TIMI RISK SCORES

Background: Thrombolysis In Myocardial Infarction (TIMI) risk score predictsadverse clinical outcomes in patients with non–ST-elevation acute coronary syndromes(NSTEACS). Whether this score correlates with the coronary anatomy is unknown. Objective:To determine the frequency of low, moderate and high TIMI risk score in patients of NSTEACSand to compare the frequency of two vessel coronary artery disease on angiography withlow, moderate and high TIMI risk scores in patients of NSTE-ACS. Study design: This was across sectional study. Setting: Department of Cardiology, Gulab Devi Chest Hospital, Lahore.Duration: Six months. Patients and Methods: Total 170 patients were included in the study.Patients’ selection was done with the help of a pre-defined inclusion and exclusion criteria. TIMIrisk score was calculated for each patient and patients were categorized into low, moderate andhigh risk groups (as per operational definition). Patients were further evaluated with coronaryangiograms to assess the double vessel CAD. All angiographies were performed by a singlephysician. Data analysis was done on SPSS version 17. Results: Mean age of our patients was54.81±10.55 years. Gender distribution shows that there were 106(62%) male and 64(38%)female patients. TIMI score risk classification showed that among 50(29.4%) patients TIMI riskscore was low, among 107(62.9%) patients it was moderate and in 13(7.6%) patients it washigh. There were 105(62%) patients who had two vessel coronary artery disease. Among 105patients who had two vessel coronary artery disease, 25(23.8%) had low TIMI score, 69(65.7%)had moderate and 11(10.5%) of the patients had high TIMI score. Conclusion: In patientswith non-ST-elevation acute coronary syndrome undergoing cardiac catheterization, the TIMIrisk score is significantly associated with two vessel coronary artery disease. So it should berecommended that a routine invasive strategy be carried in patients with moderate or higherTIMI risk score.
