Tolerance of Myocardium to Ischemia Injury (TOMIS)
August 29, 2017 updated by: University Hospital, Lille
Morning / Afternoon Variation in Myocardial Ischemia Tolerance
This study aims to understand the impact of time-of-the day on human myocardial tolerance to ischemia-reperfusion by exploring atrial myocardium biopsied during cardiac surgery.
Patients scheduled for non-urgent cardiac surgery (coronary artery by-pas graft and/or aortic valve replacement) will be assigned to a morning or an afternoon cardiac surgery based on randomization.
Myocardial biopsies will be explored in ex vivo conditions mimicking ischemia-reperfusion.
