The Timi Risk score analysis in ST-elevation myocardial infarction patients after 6 months

Abstract

Background: The TIMI RISK (TR) score for ST-Evaluation Myocardial Infarction (STEMI) was originally describes by Morrow et al. (2000), basead on 8 variables. It was used in the In TIME study as 30-day mortality predictor and several studies successfully relate TR as prognosis index for STEMI, although few reports evaluate lete evolution of these patients and the relation whith the score. Objective: Evaluating the evolution of the STEMI interned patients in University-Based Hospitals after 6 months and the relation with the TR stratification. Methods and Results: 89 patients were clinically
followed up in University-Based Hospital for 6 months after the initial determination of the TR score realized during hospital admission. The following parameters were evaluated: death, readmission for cardiovascular event, and revascularization necessity. They were classified in 3 groups according the score: Group I (0, 1, 2); Group II (3, 4, 5) and Group III (>5), were submit to statistic analysis by chisquare
test. The results of death, readmission in coronary-care unit and revascularization were respectively: GI: 4,1%, 25,0%, 20,8%; GII: 10,0%, 35,0%, 30,0%; GIII: 52,0%, 60,0%, 48,0%. Conclusion: TR score maintained significant events increase on Groups II and III comparing to Group I; presenting the possible score applicability also at long term as predictor (6 moths).
