As doencas cardiovasculares sao as principais causas de mortes nos paises desenvolvidos e subdesenvolvidos. A cirurgia de revascularizacao do miocardio - CRM e um dos procedimentos cirurgicos mais comuns apos IAM, com alta probabilidade de melhora da funcao ventricular, diminuicao dos sintomas, melhor prognostico e reducao da morbimortalidade. O objetivo da pesquisa foi avaliar a capacidade funcional e forca de quadriceps de pacientes submetidos a CRM. Foi realizado um estudo do tipo transversal, em pacientes com indicacao de cirurgia eletiva de CRM. Os pacientes realizaram o teste de caminhada de seis minutos (TC6M) e dinamometria atraves do dinamometro Microfet Handheld para avaliacao da capacidade funcional e forca do musculo quadriceps no pre-operatorio e no 5o dia do pos-operatorio, respectivamente. Houve reducao significativa da distância percorrida no TC6M no 5o PO quando comparada aos valores do pre-operatorio (p<0,05). A forca muscular do quadriceps no 5o PO nao demonstrou diferenca significante quando comparada aos valores de pre-operatorio. Apesar de apresentarem deficit na capacidade funcional no 5o dia de pos-operatorio, os pacientes submetidos a CRM apresentaram preservacao da forca muscular de quadriceps.

Abstract Cardiovascular diseases are the leading causes of death in developed and underdeveloped countries. Myocardial revascularization surgery (CABG) is one of the most common surgical procedures after AMI, with a high probability of improvement in ventricular function, a decrease in symptoms, a better prognosis and a reduction in morbidity and mortality. To evaluate the functional capacity and quadriceps strength of patients undergoing CABG. A cross-sectional study was performed in patients with elective CABG surgery. Patients underwent a sixminute walk test (6MWT) and dynamometry using the Microfet Handheld dynamometer to evaluate the functional capacity and strength of the quadriceps muscle in the preoperative period and on the 5th postoperative day, respectively. There was a significant reduction of the distance covered in the 6MWT in the 5th PO when compared to the preoperative values (p <0.05). The muscular strength of the quadriceps in the 5th postoperative did not show a significant difference when compared to the preoperative values. Although patients presented functional capacity deficit on the 5th postoperative day, patients undergoing CABG presented preservation of quadriceps muscle strength. Keywords : Muscle Strength.
