Objective
To correlate the TIMI score in patients admitted to an ICU with ST-segment elevation myocardial infarction (STEMI) with age, treatment and mortality.
Materials and methods
From July 2004 to December 2006, the data of 359 patients with ACS were collected prospectively. One hundred and fifty-six patients were admitted with STEMI and were classified by TIMI score. Statistical analysis was performed with one-way ANOVA with the Tukey post test and Pearson correlation.

Conclusion
The patient age was significantly lower in TIMI scores 0–3. The mortality increased proportionally with TIMI score. Nevertheless, there was no mortality in the higher TIMI scores, probably because of the small number of patients.
