Ventilatory Muscle Strength Six Months After Coronary Artery Bypass Grafting in Patients Submitted to Inspiratory Muscular Training Based on Anaerobioc Threshold: A Clinical Trial

Abstract

Introduction Coronary artery bypass grafting (CABG) surgery is associated with a decline in ventilatory muscle strength and lung function. Inspiratory muscle training (IMT) based on anaerobic threshold (AT) has been used to minimize the impact of CABG on these parameters, but the long-term impact is unknown. Objective To test the hypothesis that AT-based IMT improves inspiratory muscle strength and lung function even six months after CABG. Methods This is a randomized controlled clinical trial. In the preoperative period, maximum [...]
