Team Soleil

Population Health Research Program in Heart Failure and Cardiovascular Interventions (Team Soleil)

Team Soleil’s research program is based on heart failure and long-term outcomes after cardiovascular interventions. The team focuses on sex and gender epidemiology, as well as patient-oriented outcomes.

Specific projects include establishment of novel predictive approaches for perioperative right ventricular failure, determination of personalized perioperative hemodynamic goals to prevent complications in cardiac surgery, derivation and prediction of patient-defined outcomes, improving the outcomes of medical and surgical patients with heart failure, and finding solutions to disparities in access to cardiac health care. This is accomplished through a combination of interventional and observational study designs, machine learning approaches, and the integration of institutional and large population-based administrative databases.

  • Influence of sex on cardiac referral, quality indicators and outcomes in heart failure care in Ontario
  • Development and application of patient-defined outcomes after cardiac surgery
  • Comparative effectiveness of cardiac surgery vs. percutaneous interventions
  • Sex differences in long-term outcomes after cardiac interventions
  • Ischemic cardiomyopathy and left ventricular functional recovery
  • Novel biomarkers and hemodynamic markers as predictors of right ventricular failure and acute kidney injury after major cardiac surgery
  • Defining personalized perioperative blood pressure and other hemodynamic targets to prevent complications
  • Frailty
