Inspiratory muscle training on quality of life and functional capacity after hospital discharge in patients submitted to coronary artery bypass grafting: A controlled clinical trial.
Journal of bodywork and movement therapies(2023)
摘要
INTRODUCTION:There is a gap in knowledge about functional capacity and quality of life in patients undergoing coronary artery bypass grafting (CABG) after hospital discharge and the contribution of inspiratory muscle training (IMT).
OBJECTIVE:To evaluate the influence of IMT on functional capacity and quality of life after hospital discharge of patients undergoing CABG.
METHODOLOGY:Clinical trial. In the preoperative period, patients assessed maximum inspiratory pressure (MIP), quality of life using the SF-36 and functional capacity using the Six-Minute Walk Test (6MWT). On the first postoperative day, they were randomized into: control group (CG) receiving routine assistance from the hospital; intervention group(IG) in addition to conventional physical therapy and submitted to an IMT protocol based on the glycemic threshold. Being reevaluated on the day of hospital discharge and post-discharge month.
RESULTS:41 patients were included. In the preoperative period of the MIP assessment of the CG, it was 104 ± 14 cmH2O already in GI it was 103 ± 19cmH2O (p = 0.78) CG at discharge 80 ± 13 cmH2O already in GI it was 92 ± 15cmH2O(p < 0.01), revaluation CG 91 ± 11 cmH2O versus 98 ± 12 cmH2O (p < 0.01) of the IG. In the 6MWT the preoperative of the GC group was 420 ± 70 m already in GI it was 429 ± 71 m (p = 0,89), CG at discharge 326 ± 79 m versus 373 ± 55 m and revaluation of the CG 377 ± 75 m and IG 410 ± 57 m (p < 0.01). Functional capacity, general health status, emotional aspects and limitations due to physical aspects were significant when the three moments were compared.
CONCLUSION:IMT increases functional capacity, inspiratory muscle strength and quality of life after discharge from patients undergoing CABG.
