Experiencia en un programa de rehabilitación cardíaca extrahospitalario usando cardiotacómetros. Seguridad y eficacia

Abstract

Introduction: physical exercise, integrating cardiac rehabilitation (CR), has a proven positive effect on the prog-nosis of patients with cardiovascular disease, optimizing cardiac performance in terms of functional capacity. CR programs aim to obtain maximum clinical benefits with minimal risks to the patient. Objectives: assess the safety and efficacy of a cardiotachometer-monitored out-of-hospital CR program in high-and moderate-risk patients, based on the absence of major cardiac complications and improvement in participant’s functional capacity. Materials and methods: retrospective cohort study, submitted to a CR plan for 12 weeks in the period between January 2014 and March 2020. Clinical and functional parameters were evaluated at the beginning and at the end of the rehabilitation plan, controlling effort tolerance, blood pressure and heart rate using cardiotachometers. Results: 181 patients were included, aged 58.7 ± 9.7 years and 87.8% female, of whom 90% were carriers of ischemic heart disease. According to the classification of the American Association of Cardiovascular and Pulmonary Reha -bilitation, the patients were distributed as follows: 54 (29.8%) at high risk, 29 (16.0%) at intermediate risk, and 98 (54.1%) low risk. In more than ten thousand hours of physical activity performed, one patient required implantation of a permanent pacemaker due to complete atrioventricular block. A significant improvement (p = 0.001) of the func tional capacity, from 7.34 ± 2.68 to 10.2 ± 2.35 (mean relative improvement: 28.1%.) was obtained. Conclusions: the CR is a safe and effective procedure for cardiac patients, even in moderate or high-risk subjects. The use of cardiotachometers allows adequate exercise monitoring and timely detection of complications.
