An inhospital complication requiring ICU level of care was defined as death. Procedural success was <50 residual stenosis with antegrade TIMI flow grade 3 at the end of the procedure. TIMI risk score correlates well with the frequency of electrical or mechanical complications and death after STEMI. Thrombolysis in Myocardial Infarction (TIMI) Risk Score for STEMI was computed retrospectively, as previously described. The GRACE model demonstrated better discrimination than the TIMI score in predicting long-term mortality (p 0.028 for 1year, and 0.009 for 3 years). Frequency of complications and death correlated well with TIMI risk score (p = 0.001). The performance of the TIMI score was somewhat inferior to the GRACE risk model (C-statistics range 0.684 to 0.738 for all-cause mortality, and 0.695 to 0.748 for triple endpoints). Post MI arrhythmias were noted in 2.2%, 16% and 50% cardiogenic shock in 6.7%, 16% and 60% pulmonary edema in 6.7%, 20% and 80% mechanical complications of MI in 0%, 8% and 30% death in 4.4%, 8%, and 60% of patients belonging to low-risk, moderate-risk and high-risk groups respectively. The frequencies of complications and deaths were compared among the three risk groups. The patients were divided into three risk groups, namely 'low-risk', 'moderate-risk' and 'high-risk' based on their TIMI scores (0-4 low-risk, 5-8 moderate-risk, 9-14 high risk). Several scores have recently been proposed, derived either from clinical trials (eg, the Thrombolysis in Myocardial Infarction TIMI score, 1,2 the Platelet glycoprotein IIb/IIIa in Unstable angina: Receptor Suppression Using Integrilin Therapy trial PURSUIT score, 3 the Intravenous nPA Treatment of Infarcting Myocardium Early II InTIME II. TIMI risk score was calculated for each case at the time of presentation and were then followed during their hospital stay for the occurrence of electrical and mechanical complications as well as mortality. The study included 160 cases of STEMI eligible for thrombolysis. To evaluate the prognostic significance of TIMI risk score in a local population group of acute STEMI. The Thrombolysis in Myocardial Infarction (TIMI) risk score for ST-segment elevation myocardial infarction (STEMI) is a simple integer score based on 8 high-risk parameters that can be used at the bedside for risk stratification of patients at presentation with STEMI. Several studies show that the neutrophil to lymphocyte ratio (NLR) is a prognostic inflammatory marker. Effective risk stratification is integral to management of acute coronary syndromes (ACS). Introduction: The thrombolysis in myocardial infarction (TIMI) risk score is calculated as the sum of independent predictors of mortality and ischemic events in ST elevation acute myocardial infarction (STEMI).
