ABSTRACT

Introduction: Several investigations have addressed the identification of clinical markers for the risk of sudden cardiac death in acute myocardial infarction.
Objectives: To determine the risk factors for this type of death in patients with acute myocardial infarction.
Methods: A case-control analytical study was conducted at the Department of Cardiology in Las Tunas from 2011 to 2017. The study population consisted of 1150 patients admitted for myocardial infarction previously registered in the department's database. The 45 patients who died from sudden death made up the “case group” and for each of them, 2 patients —who did not die suddenly— were random-ly assigned to the “control group”. Descriptive statistics were used for descriptive variables. To assess risk factors, multivariate analyses were performed and the odds ratio (OR) was evaluated with 99% reliability.
Results: Male sex predominated in both groups and high blood pressure was the most frequent associated factor. Mean age and Killip-Kimball class III-IV percent-age were similar. A 43% of patients with sudden death were diabetic and presented a higher percentage of biventricular infarctions (22.7%), ineffective thrombolysis (41.8%), and cardiac rupture (13.6%). Glycemia >15.0 mmol/L on admission (OR 2.57; p=0.027) and ineffective thrombolysis (OR 2.19; p=0.024) were associated with the occurrence of sudden death.
Conclusions: Both, Glycemia >15.0 mmol/L on admission and ineffective thrombo-lysis, behaved as risk factors for sudden death.
