Introduction:

Establishing the adequate prognosis in patients with acute myocardial infarction contributes to differentiate their follow-up and facilitates when deciding which specific conduct will determine the best result in its course.

Objective:

To identify prognostic factors of hospital mortality in patients with ST elevation myocardial infarction.

Methods:

It was performed a case-control analytic study in patients admitted with ST elevation myocardial infarction in “Arnaldo Milián Castro” hospital during 2015. The case group was integrated by deceased patients (n=15) and the control group by living patients (n=60). During admission, demographic, hemodynamic and laboratory variables were evaluated, and a binary logistic regression was made to identify the predicting factors.

Results:

Medium age (74.13±7.80), glycemia (14.2±10.3) and Leuko-glycemic index (3.097±2.666) were significantly higher in the case group. Electrical (OR:2.00; CI:1.767 to 20.369) and hemodynamic complications (OR:2.00; CI:1.398 a 2.860) predominated in deceased patients. Multivariate analysis identified serum creatinine (OR:1.013; CI:1.010 to 1.027), coronary reperfusion therapy (OR:0.206; CI:0.049 to 0.868) and Killip-Kimball classification (OR:8.311; CI:1.511 to 45.720) as prognostic factors of mortality.

Conclusions:

The serum creatinine levels, coronary reperfusion therapy and Killip-Kimball classification constituted the prognostic factors of hospital mortality for patients with ST elevation myocardial infarction. An early identification of those factors could indicate that patients need a closer follow-up during admission to improve their prognosis. MÉD. UIS. 2017;30(3):67-72.
