Unstable angina and non-ST-segment elevation myocardial infarction: an analysis by TIMI score


The TIMI score was created to categorize a patient's risk of death and ischemic events, providing the basis for therapeutic decision-making. In this study, the characteristics of patients with acute coronary syndrome (ACS) were analyzed using the TIMI score.

Materials and methods

From July 2004 to December 2006, the data of 359 patients with ACS were collected prospectively. Two hundred and three patients out of the initial 359 patients were admitted with unstable angina and non-ST-segment elevation myocardial infarction (NSTEMI) and were classified by the TIMI score. Statistical analysis was performed with one-way ANOVA with the Tukey post test and Pearson correlation.


Of the 203 patients, 92 had unstable angina and 111 had NSTEMI. The mean age was 66.3 years, and 65.5% were men. The details of each group of TIMI score are shown in Table 1. The groups that were submitted to angioplasty and myocardial revascularization surgery (MRS) had no mortality.

Table 1 Table 1


The mortality was higher in the group with clinical treatment. The age was a determinant of higher mortality when compared with the TIMI score. There was no correlation of the TIMI score and mortality.
