ABSTRACT

Background: Cardiovascular ischemic disease is the first cause of mortality in Mexico within the mature population of more than 20 years. Myocardial acute infarction with elevation of ST-segment has a 34.8% of mortality.
Objective: To determine the mortality prognostic value on 30 days for an index of prognosis formed by three variables: heart rate, age, and systolic arterial pressure in patients with myocardial acute infarction and ST-segment elevation at intensive care unit.
Material and methods: Retrospective, longitudinal, and observational study of 249 files, 131 with myocardial acute infarction and STsegment elevation. Risk of mortality within 30 days formula (prognostic index = heart rate x [age/10]2/systolic arterial pressure) was applied for the first six hours of admission to emergency and the first 24 hours of admission to intensive care unit.
Results: In 131 patients with myocardial acute infarction and ST-segment elevation (52.6%), with age average of 61.7 ± 11.8 years, 30 days mortality was 22.9% (30, IC 95%, 22.26-25.53). Prognosis qualification was higher than 30, OR = 3.31 and p value higher than 0.05.
Conclusions: Prognostic risk factors lower than 30 are not significant to predict mortality within 30 days of myocardial acute infraction and ST-segment elevation evolution.
