Brief Summary
The main objective of this study is to evaluate the effect of pre-operative Inspiratory muscle training (IMT) using an IMT Threshold device (Philips), on early postoperative lung function recovery and on the occurrence of post-operative pulmonary complications (PPC) after major cardiothoracic surgery with and without sternotomy. As frailty can affect postoperative outcome, the relation between frailty, maximal inspiratory pressure (MIP) and post-operative outcome is investigated additionally.
