Â The objective of this study was toÂ evaluate the effects of a 6-day postoperative in-hospital cardiopulmonary rehabilitation program on inspiratory muscle strength and its potential association with improved functional capacity after coronary artery bypass graft (CABG) surgery.Â Twenty Â men were randomisedÂ to receive either usual care or a six-dayÂ cardiopulmonary rehabilitation programÂ following CABG.Â The rehabilitationÂ included the use of expiratory positive airway pressure mask and bronchial hygiene techniques, coupled with progressive distance walking and calisthenics as well as cardiopulmonary training.Â Maximal inspiratory and expiratory pressure was measured at intervals,Â Â six-minute walk test (6MWT) was performed 7 days after surgery, and maximal cardiopulmonary exercise testing was performed 30 days after surgery. All three measures were significantly betterÂ for the rehabilitation group.Â
In summary aÂ 6-day rehabilitation program attenuated the postoperative reduction in respiratory muscle strength and also improved the recovery of functional capacity after CABG.
