ASSESSMENT OF FUNCTIONAL CAPACITY AND PHYSICAL LIMITATION IN SUBJECTS SUBMITTED TO MYOCARDIAL REVASCULARIZATION

Abstract

Objective: To evaluate the functional capacity and physical limitation in patients submitted to coronary artery bypass graft (CABG) at six months after surgery. Material and Methods: 28 patients with coronary artery disease who underwent CABG between November 2008 and April 2009 were included in this study. Their functional capacity and physical limitation were approached considering the respective domains present in the standardized questionnaire Medical Outcomes Study Short Form (MOS-SF), as well as the level of physical activity through the International Physical Activity Questionnaire (IPAQ), in the period of six months after the CABG. Results: There were significant differences before and after surgery for the domains "functional capacity" (41.79 vs. 70.18; p <0.001) and "limited by physical aspects" (3.57 vs. 35.71 p <0.001). It was shown that patients classified as "active" by IPAQ had significantly higher scores than those rated as "sedentary" for the domain "functional capacity" (81.07 vs. 45.00; p = 0.012) and also higher than those classified as "insufficiently active" (58.93 vs. 11.11; p = 0.006) and "sedentary" (58.93 vs. 15.00; p = 0.006) for the domain "limited by physical aspects." Conclusion: There was an increase in the scores of the domains "functional capacity" and "limitation by physical aspects" six months after CABG, which translates into increased ability to perform activities that could not be performed preoperatively. The improvement of these areas was more significant in subjects who practiced regular physical activity after surgery. DESCRIPTORS Motor Activity. Myocardial Infarction. Sedentary Lifestyle.
