Abstract

Introduction and Objectives: Infarct size and the effect on ventricular function are significant problems for the patient's prognosis. The aim of this study was to assess poor prognostic factors prior to hospital discharge by performing submaximal ergometry and echocardiogram. Material and Methods: A descriptive, prospective study was performed on 85 patients with infarction who received or not thrombolytic therapy, in the University Hospital "Dr. Celestino Hernandez Robau" Santa Clara, and who underwent ergometry and echocardiography prior to hospital discharge in order to identify  poor prognosis variables. Results: Males were predominant (82.2%), the group aged 55 years and over (47,1 %), hypertension (80%) and smoking (75,2 %). The most common location was the posterior-inferior (78.8 %)  left ventricle ejection fraction was better in patients treated with thrombolysis, and those who had poor ventricular function were identified (10.6%), 74,1 % had functional class I and 21 patients (24,7 %) with poor prognosis were identified. There was no significant difference compared to thrombolytic therapy, but the patients who received it had a better clinical behavior. Conclusions: There were 31 patients with positive stress testing and poor prognosis, 5 of them with functional class III, which also showed decreased LVEF. Submaximal exercise testing and two-dimensional echocardiography are first-choice tools in the prognostic assessment of patients with AMI, due to its existence in almost all hospitals, low cost, little or no risk and easy to perform, and reproduce.
