Predictive factors of mortality in ST-segment elevation acute myocardial infarction

Introduction: Cardiovascular diseases are the top cause of mortality worldwide. Although the incidence of myocardial infarction has decreased substantially in the United States in recent decades, they have not ceased to have a strong socioeconomic and occupational impact. Objective: To identify predictive factors of mortality in patients with ST-segment elevation myocardial infarction (STEMI). Method: An analytical study was carried out in 118 patients, admitted to two hospitals in Santiago de Cuba, from January 2017 to December 2019. Data analysis was based on the construction of a multivariate model (multivariable logistic regression) to identify predictors of mortality. Results: There were 15 deaths in total during hospitalization period. In the research, men marked the difference, without being able to statistically associate this gender variable with mortality; however, age over 80 years old (RR 7.89; 95% CI: 1.97-7.93; p<0.0001), cardiogenic shock (RR 8.12; CI 95%: 2.85-9.18; p=0.001), not ap-plying thrombolysis (RR 9.13; CI 95%: 3.32-9.45; p=0.001), therapeutic window greater than six hours (RR 16.96; CI 95%: 9.79-62.90; p<0.0001), and the inferior wall myocardial infraction (RR 7.89; CI 95%: 1.97-7.93; p<0.0001), showed a highly signif-icant statistical association with mortality. Conclusions: Some predictive factors of mortality were identified for STEMI, where age older than 80 years old, cardiogenic shock and a therapeutic window longer than six hours stand as the main causal factors in the pathophysiological and statistical explanation of mortality.
