APPLICATION OF THROMBOLYSIS IN MYOCARDIAL INFARCTION (TIMI) RISK SCORE IN PATIENTS WITH ST ELEVATION MYOCARDIAL INFARCTION UNDERGOING PRIMARY PERCUTANEOUS CORONARY INTERVENTION

Objective: The purpose of study was to determine whether thrombolysis in myocardial infarction (TIMI) risk score applied to patients undergoing primary percutaneous coronary intervention identifies a group of patients at high risk for adverse outcome.
Study Design: Descriptive cross sectional study.
Place and Duration of Study: Study was conducted at AFIC/NIHD Rawalpindi from June 2014 to Dec 2014.
Methods: We studied patients with STEMI who were treated with primary PCI. The TIMI risk score was calculated to determine its predictive value for in hospital mortality. Patients were divided into two groups according to their TIMI risk score. Low risk being 0-4 points and high risk >/5 and the frequency of adverse events was analyzed.
Results: we analyzed 102 patients. Thirty (29.4%) patients classified as high risk (TIMI >/5) had higher incidence of adverse events than the low risk group: mortality 13.3% vs. 0, (p=.002), heart failure 16.6% vs. 4.1 (.032), cardiogenic shock 13.3% vs.1.3% (p=.011), ventricular arrhythmias 23.3% vs. 5.5% (p=.008)
Conclusion: TIMI risk score for STEMI can predict in hospital mortality and identifies a group of high risk patients who might develop adverse events.
