Characterization of patients with acute myocardial infarction of lower topography

Abstract

Background: acute myocardial infarction is one of the life-threatening conditions and the most important parameter to measure in the occurrence of adverse cardiovascular events. Objective: to characterize patients with a diagnosis of acute myocardial infarction of lower topography, attended at the Center for Cardiovascular Surgery and Cardiology, in the Provincial Hospital Clínico Quirúrgica Docente "Saturnino Lora Torres" from January, 2018 to November, 2022. Methods: a descriptive, longitudinal and retrospective investigation was carried out in the center and time period declared in the objective. The universe consisted of 330 patients with this diagnosis, choosing by simple random sampling, a sample of 177 patients. Clinical-epidemiological, echocardiographic and therapeutic variables were evaluated. The information was collected from data on individual medical records and echocardiographic reports. Results: patients aged 65 or older predominated (70.6 %), with a discrete greater presence of males (55.4 %). 137 (77.4 %) patients had complications (p = 0.0001), the most frequent was paroxysmal atrial fibrillation (16 %), followed by right ventricular infarction (10 %). Most patients received thrombolytic therapy (69.5 %). There was an association between altered values of: left ventricular systolic function, right ventricular tissue doppler, left atrial pressure, left atrial volume and the presence of complications. Conclusions: patients with acute myocardial infarction of lower topography included in the study were characterized.
