To the Editor: Dr Hulzebos and colleagues1 designed a single-blind, randomized clinical trial to study the prophylactic efficacy of preoperative physical therapy, including IMT, on the incidence of postoperative pulmonary complications (PPCs) in patients at high risk for these complications who underwent CABG surgery. We have 3 concerns about the patients in the study who had advanced cardiac disease.
