ABSTRACT
Introduction: Acute myocardial infarction with ST elevation is a major cause of mortality in Holguin.Objective: To identify prognostic factors of in-hospital mortality in patients with ST segment elevation myocardial infarction (STEMI).
Methods: A cohort study of ill patients in a sample of 227 patients with STEMI, from the universe of admissions to the Coronary Intensive Care Unit of Vladimir Ilich Lenin Hospital, Holguín, Cuba, between February 2014 and January 2015. The mean difference and chi-square tests were used in the SPSS Statistics program. The Odds Ratio (OR) of the identified prognostic factors and their 95% confidence intervals (CI95%) were determined, with a significance level of 5% (p<0.05).
Results: The result, dead at discharge, showed association with the female sex (OR=4.072; IC95%=1.7-8.9), the previous topography (OR=2.448; IC95%=1.1-5.3), the highest degrees of pump failure (OR=15.95; IC95%=7,55-51,94), re-infarction (OR=16,42; IC95%=2,9-72,1), mechanical complications and electrical complications (OR=2,66; IC95%=1,1-6,7). Those who died on discharge had a significantly higher mean age (72.89 years SD 11.05) than those who were alive on discharge (65.62 years SD 8.92) (p=0.045).
Conclusions: There are demographic, clinical, electrocardiographic and hemodynamic variables in patients with STEMI that are predictive of in-hospital death.
