ABSTRACT

Introduction: Microalbuminuria (MA) is an endothelial dysfunction biomarker, and has been associated to higher morbidity and mortality in cardiovascular disease. The ischemic heart disease is among the leading causes of death, and it’s necessary to study new risk and prognostic biomarkers in patients with ST-elevation acute myocardial infarction (ST-AMI). Objective: To determine the predict value of microalbuminuria in patients with ST-AMI. Material and methods: We developed an observational, longitudinal, prospective and analytical cohort study, patients older than 18 years old, any sex, within 24 hours evolution ST-AMI were included. Exposed cohort was defined as MA ‹ 20 µ g/min in a 24-hour urine sample within 72 hour of myocardial infarction, and were followed for 30 days and cardiovascular events were recorded. Results: We studied 99 patients; 51 (51.5%) presented MA. Basal clinical features were not significantly different. MA subjects had higher APACHE II, TIMI, EUROSCORE and GRACE scores (p › 0.05 for all). Killip-Kimball ≥ III, arrhythmia, advanced atrioventricular block, cardiogenic shock, re-infarction and death were significantly associated to MA (p › 0.05 for all), and this association remains as an independent death predictor adjusted to TIMI and GRACE scores and right ventricle infarction. In the same way, MA is associated with lower survival rate at 30 day, p = 0.002. Conclusions: Microalbuminuria is an independent risk factor for death at 30 days, and should be included as part of biochemical markers in patients with ST elevation acute myocardial infarction.
