Coronary Artery Disease Clinical Trial
Official title:
Cardiopulmonary Exercise Testing as an Outcome Predictor in Coronary Artery Bypass Surgery
This is a prospective cohort study of patients undergoing coronary artery bypass graft surgery. Prior to surgery, participants will undergo submaximal cardiopulmonary exercise testing on a treadmill. Participants will be followed for one month after surgery to assess mortality and non fatal complications.
Coronary artery bypass surgery (CABG) is a complex and expensive procedure with great
potential for morbidity and mortality. Preoperative evaluation is of paramount importance to
optimize results. There is much evidence about the benefits of the cardiopulmonary exercise
testing (CPET) in the evaluation of preoperative risk in non-cardiac surgeries. Thus, it is
important to evaluate the relationship between parameters obtained in the CPET and the
outcomes after cardiac surgery, especially CABG.
This is a prospective cohort study in which participants undergo submaximal CEPT on a
treadmill prior to CABG. Participants will be followed up for one month after surgery to
assess mortality and non fatal complications. It is expected that poor cardiopulmonary
fitness is related to worse outcomes in CABG, as already observed in other cardiac
pathologies and in non-cardiac surgery.
