Cardiac Anesthesiology Research

Research continues to play an important part of the mission of the Division of Cardiac Anesthesiology as we continually strive to improve patient care. Research focuses on predicting perioperative risk, characterization of patient outcomes and tailoring patient care towards prevention of adverse events during all stages of the perioperative period. Our perioperative database has enabled the division to develop a CARE risk score predicting morbidity and mortality after cardiac surgery, assess post-surgical severity of illness in the intensive care unit (ICU) as well as monitor quality measures and targeted outcomes of interest. 

We work in close collaboration with our surgical and allied health colleagues from the institute, other departments and cardiac centres to participate in multi-center trials and investigator driven studies.

We are supported by a research coordinator and research assistant along with the regular participation of students, residents and fellows.


Current research themes include:

  • Use of new technologies and techniques for perioperative monitoring and to directing patient management
  • Prediction and prevention of postoperative atrial fibrillation
  • Blood product conservation and use of point-of-care devices
  • Prediction and evaluation of diastolic dysfunction 
  • Assessment of right heart function and prediction of postoperative right heart failure
  • Hemodynamic markers for stroke prevention and renal injury
  • Severity of illness in the ICU and predictors of long ICU stay
  • Postoperative delirium and management
  • Long-term outcomes after discharge from cardiac surgery
