Avaliação pré e pós-operatória da força muscular respiratória e periférica e da capacidade funcional em pacientes submetidos à cirurgia cardíaca

Abstract

Cardiovascular diseases (CVDs) have been gaining increasing attention in recent years and are associated with high morbidity and mortality rates in Brazil and worldwide. One of the treatment options is cardiac surgery, which, according to the literature, is linked to postoperative pulmonary and systemic complications. The aim of this study was to evaluate respiratory muscle strength (RMS), peripheral muscle strength (PMS), and functional capacity in the pre- and postoperative periods in patients undergoing elective cardiac surgery. Seven patients aged between 22 and 63 years participated in the study. They were admitted to the Hospital de Clínicas of the Federal University of Uberlândia (HC-UFU) and were assessed the day before the surgical procedure and on the 5th postoperative day using manovacuometry, handgrip dynamometry, and the 30-Second Sit-To-Stand (30SSTS). Data analysis was performed using the statistical software R version 4.3.0. The results showed a reduction in RMS, PMS, and functional capacity on the 5th postoperative day in patients undergoing elective cardiac surgery. Thus, it was concluded that cardiac surgery has a negative impact on these variables.
