Myocardial infarction is a leading cause of death worldwide.  Although prompt reperfusion is crucial to reduce the infarct size and improve survival, it can paradoxically induce injury itself, leading to functional and metabolic disruptions of the heart as well as morphological changes. Cardioprotective strategies are developed to reduce the impact of reperfusion injury in experimental models and in randomized clinical trials.

Our aim is to investigate, using experimental and clinical approaches, the molecular and cellular mechanisms underlying myocardial ischemia/reperfusion injury and left ventricular remodeling after myocardial infarction.

 

Isolated mouse ventricular cardiomyocytes.

 

Technical platform : Cardiac function in vivo, ex vivo, in vitro

 

In vivo exploration

  • Echocardiography Doppler (Vivid 7, GE Healthcare)
  • Implantable telemetry ECG (DSI)
  • Hemodynamics (Millar pressure catheter)
  • Myocardial infarction models (mice and rats): myocardial ischemia/reperfusion, permanent coronary artery occlusion

Ex vivo cardiac function

  • Langendorff isolated perfused heart (mice and rats) with monitoring of hemodynamic parameters (EMKA Technologies, ADInstruments)

In vitro

  • Hypoxia/reoxygenation on isolated adult and neonatal cardiomyocytes (rat, mice) and H9C2 cell line
