ABSTRACT
Abstract Background:
Risk stratification on admission of patients with acute ST-elevation myocardial infarction (STEMI) is considered a clear strategy for effective treatment, early intervention, and survival.Objective:
The purpose of this study was to determine the risk factors for in-hospital mortality from cardiac causes after STEMI.Methods:
Observational, retrospective, longitudinal study, with a quantitative approach, based on data from the medical records of individuals diagnosed with STEMI treated at the Emergency Room of a large hospital in the state of Minas Gerais, Brazil, from January 2011 to July 2016. The outcome of interest was 30-day in-hospital mortality from after STEMI. For statistical analysis, the Pearson's chi-square test, Spearman's correlation and multivariable Cox-regression analysis were used, with a significance level of α = 0.05.Results:
Of the 459 patients, 55 (12%) died from cardiac causes within 30 days after STEMI. Mean admission SBP of these patients was 109.08mmHg. The incidence of death was higher in women (23.7%), patients with systemic arterial hypertension (SAH) (13.8%) and elderly patients (16.5%). The elderly — heart rate (HR) = 3.54 — and women — HR = 2.55 — had a statistically significant higher risk of progressing to death when compared to younger adults and men. The highest admission SBP had a protective effect (HR = 0.97), reducing the chance of death by 3%.Conclusion:
SBP on admission, female gender and advanced age were significant risk factors for death within 30 days after STEMI.
