Evidence derived from small trials suggests that preoperative physical therapy reduces postoperative pulmonary complications ( atelectasis and pneumonia ) and length of hospital stay in patients undergoing elective cardiac surgery .
There is a lack of evidence that preoperative physical therapy reduces postoperative pneumothorax , prolonged mechanical ventilation or all-cause deaths
BACKGROUND After cardiac surgery , physical therapy is a routine procedure delivered with the aim of preventing postoperative pulmonary complications .
OBJECTIVES To determine if preoperative physical therapy with an exercise component can prevent postoperative pulmonary complications in cardiac surgery patients , and to evaluate which type of patient benefits and which type of physical therapy is most effective .
Comparison of 19 pre-operative risk stratification models in open-heart surgery.
AIMS To compare 19 risk score algorithms with regard to their validity to predict 30-day and 1-year mortality after cardiac surgery . METHODS AND RESULTS Risk factors for patients undergoing heart surgery between 1996 and 2001 at a single centre were prospect ively collected . Receiver operating characteristics ( ROC ) curves were used to describe the performance and accuracy . Survival at 1 year and cause of death were obtained in all cases . The study included 6222 cardiac surgical procedures .  Actual mortality was 2.9 % at 30 days and 6.1 % at 1 year . Discriminatory power for 30-day and 1-year mortality in cardiac surgery was highest for logistic ( 0.84 and 0.77 ) and additive ( 0.84 and 0.77 ) European System for Cardiac Operative Risk Evaluation ( EuroSCORE ) algorithms , followed by Clevel and Clinic ( 0.82 and 0.76 ) and Magovern ( 0.82 and 0.76 ) scoring systems . None of the other 15 risk algorithms had a significantly better discriminatory power than these four . In coronary artery bypass grafting (CABG)-only surgery , EuroSCORE followed by New York State ( NYS ) and Clevel and Clinic risk score showed the highest discriminatory power for 30-day and 1-year mortality . CONCLUSION EuroSCORE , Clevel and Clinic , and Magovern risk algorithms showed superior performance and accuracy in open-heart surgery , and EuroSCORE , NYS , and Clevel and Clinic in CABG-only surgery . Although the models were originally design ed to predict early mortality , the 1-year mortality prediction was also reasonably accurate
