[TIMI risk score validation for patients with acute coronary syndrome without ST elevation].
Non-ST elevation acute coronary syndromes (NSTE-ACS) are frequent cause of hospitalization, being responsible for 10-15% of infarcts or deaths per year. The study was designed to analyze 6 months follow-up of cardiovascular events as well as to validate the Thrombolysis in Myocardial Infarction (TIMI) risk score for patients hospitalized for NSTE-ACS. We retrospectively analyzed patients admitted with NSTE-ACS. Telephone follow-up were performed at 6 month. Combination of death, re-admission for acute coronary syndrome and revascularization were considered as end point. Two hundred and four patients were included for the analysis. There were 70.2% males, with a mean age of 64.5 +/- 11.8 years. After the initial evaluation, we diagnosed unstable angina in 34.6% of cases, MI in 38.9% of cases, and 26.4% of patients were categorized as "non coronary chest pain". Applying the TIMI risk score, 52 (25.5%) patients had low risk, 106 (52%) intermediated risk, and 46 (22.5%) high risk. The global mortality was 12.3%. We found a progressively and significant increase in the rate of combined events as the TIMI score increase (p < 0.001). We conclude that in our population, the intermediated and high TIMI risk score was well related to newer cardiovascular events at 6 month follow-up.
