Why the study?
Myocardial ischemia occurs during open heart surgery due to cardiopulmonary bypass stress, aortic cross-clamp coronary flow interruption, and subsequent reperfusion.
Do coronary sinus lactate and troponin T levels correlate with perioperative outcomes in patients undergoing cardiac surgery on cardiopulmonary bypass?
Do coronary sinus lactate and troponin T levels correlate with perioperative outcomes in patients undergoing cardiac surgery on cardiopulmonary bypass?
This study aims to evaluate the correlation between coronary sinus lactate and troponin T levels and perioperative outcomes in patients undergoing cardiac surgery on cardiopulmonary bypass.

Coronary sinus lactate and troponin T monitoring during CPB may refine ischemia detection; leaves open optimal thresholds and clinical adoption in CABG or valve surgery.
Myocardial ischemia is a metabolic phenomenon that occurs in patients undergoing open heart surgery like coronary artery bypass grafting (CABG), valvular heart surgery, vascular surgeries etc., due to stress imposed during cardiopulmonary bypass (CPB), obligatory interruption of coronary blood flow during aortic cross clamp and reperfusion after aortic cross clamp release. The present study is designed to have a detailed study on estimation of coronary sinus lactate and troponin t levels in patients undergoing cardiac surgery with cardiopulmonary bypass and its correlation with various parameters related to the perioperative outcomes.
