Using Cardiopulmonary Exercise Testing to Predict Complications After Coronary Artery Bypass Graft Surgery

What this Trial Is About

Researchers are studying the use of cardiopulmonary exercise testing CPET to predict complications after coronary artery bypass graft CABG surgery. CPET is considered a gold standard for evaluating high-risk patients before major surgery, but its role in heart surgery is not well understood. The study focuses on certain exercise parameters, including the partial pressure of end-tidal carbon dioxide PETCO2 and the VEVCO2 slope, which may help predict mortality and complications after surgery. Patients scheduled for CABG surgery will undergo CPET before their operation. This diagnostic test involves measuring how well the heart and lungs perform during exercise. After surgery, researchers will monitor the patients for any cardiovascular or pulmonary complications within 30 days. The study will also track the length of hospital and intensive care stays during this period. Participants will be closely observed throughout the study period, with data collected from the CPET and post-operative monitoring. Researchers will evaluate the occurrence of complications within 30 days after surgery to assess how well CPET predicts outcomes. This observational study will help determine if CPET parameters can improve risk assessment for patients undergoing heart surgery.
