Assessing exercise capacity in patients undergoing heart surgery

Cardiopulmonary Exercise Testing in the Prediction of Post-operative Complications in Patients Undergoing Coronary Artery Bypass Graft Surgery

Observational St. Anne's University Hospital Brno, Czech Republic · NCT06702059

What this trial studies

This observational study evaluates the prognostic role of cardiopulmonary exercise testing (CPET) in patients scheduled for coronary artery bypass graft surgery. It aims to determine whether specific parameters from CPET, such as the partial pressure of end-tidal carbon dioxide and the VE/VCO2 slope, can predict postoperative complications and mortality. The study focuses on high-risk patients, particularly the elderly with significant comorbidities and frailty, to improve pre-operative risk assessment. By analyzing these parameters, the study seeks to enhance the understanding of postoperative outcomes in cardiothoracic surgery.

Who should consider this trial

Good fit: Ideal candidates for this study are patients scheduled for coronary artery bypass graft surgery.

Not a fit: Patients who are unable to perform cardiopulmonary exercise testing or those undergoing off-pump revascularization may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved risk stratification and better management of patients undergoing heart surgery, potentially reducing postoperative complications.

How similar studies have performed: While limited studies have explored CPET in cardiothoracic surgery, recent findings suggest its feasibility and potential prognostic value, indicating a promising area of investigation.
