CARDIOVASCULAR RESPONSE TO THE 50M WALK TEST IN PATIENTS WITH ACUTE MYOCARDIAL INFARCTION AND UNSTABLE ANGINA

Abstract

Introduction: The acute phase of rehabilitation in patients with Acute Coronary Syndrome (ACS) aims to reduce the deleterious effects secondary to bed rest, the autonomic changes and reduced hospital stay. The 50-m walk test (TC50m) is a noninvasive, simple, with the proposal to monitor the circulatory response in the face of a gravitational and physical  effort in patients with unstable angina (UA) and Acute Myocardial Infarction (AMI) stable. Objective: To assess the circulatory response to TC50m in patients with AMI and UA. Methods: This clinical trial type, given to patients hospitalized in coronary care unit with ACS, stable clinical conditions for the realization of the walk. Circulatory variables were monitored: blood pressure (BP), heart rate (HR), double product (DP) Saturation (Spo2), and the Borg Scale (EB) during gravitational stress and physical data were analyzed by SPSS 14.0 considering a significance level of 5%. Results: Of 65 patients evaluated, 36 (54.8%) AMI, and 29 (45.2%) AI, there was an increase of circulatory variables during the EG and during the walk, but at the end of the walk there was a reduced values when compared with the values obtained in the supine position, but no significant difference between groups. Conclusion: The TC50m is tolerable for patients with ACS regardless of clinical classification, it was found that patients with MI or UA have similar circulatory responses with functional capacity adequate to stress proposed.
