To determine whether pre-operative pulmonary ventilation function and muscle strength were associated with length of stay in hospital in patients after coronary artery bypass graft surgery (CABG).
Our study population comprised 70 subjects (mean ± SD age: 62.7 ± 7.7 years; 66.2% men) who undergoing CABG. All patients were told to some simple assessments, including pulmonary ventilation function (forced vital capacity, FVC; maximal voluntary ventilation, MVV) and muscle strength (grip) before surgery.
In multivariate analysis, after adjust gender, age, the severity of coronary heart disease, history of other diseases, daily living activity (IPAQ), smoke status, drinking status, psychological conditions and surgery situations, we found that adequate pulmonary ventilation function (FVC OR 3.93, 95% CI 1.77-10.10; MVV OR 1.98, 95% CI 1.16-9.40) and muscle strength (grip OR 5.76, 95%CI 1.44-23.06) were independently associated with shorter length of hospital stay after CABG.
We conclude that pre-operative pulmonary ventilation function and muscle strength may contribute to the prediction of outcomes of CABG.
