Comparison of the TIMI risk score with coronary angiography in patients with ST-segment elevated myocardial infarction, unstable angina and non ST-segment elevation myocardial infarction.

Abstract

 In 1983, the TIMI (Thrombolysis in Myocardial Infarction) study group 
(Brigham and Women's Hospital, Boston, Massachusetts) chose to conduct a randomized, 
double-blind, multicenter study to assess the efficacy of intravenous (IV) streptokinase. Phase 
1 
IV streptokinase and IV tPA (tissue plasminogen activator) and 
assessed "recanalization of the totally occluded artery 90 minutes after the start of drug 
infusion." For this study, the TIMI Coronary Grade Flow was established to ensure a uniform 
and consistent method of recording epicardial perfusion on coronary arteriography. Objective: 
The present study aims to systematically compare the TIMI risk score with coronary 
angiography in patients with ST-segment elevated myocardial infarction, unstable angina and 
non-ST-segment elevation myocardial infarction. Materials and methods: This is a 
prospective cross-sectional study to evaluate correlation between TIMI score and number of 
vessels involved in angiographic study of STEMI, NSTEMI and UA patients presenting to 
BLDE hospital. Results: The symptom distribution in this study reveals that the most prevalent 
symptom is "Chest Pain, Radiating Pain" (31.58%), followed by "Chest Pain" alone (29.47%).
