About Sidney Levitsky, MD

Cheever Professor of Surgery, Harvard Medical School


Research Focus

The primary focus of the laboratory is to elucidate the mechanisms and subcellular localization of biochemical and molecular events contributing to myocardial cell death. In particular, we are interested in the discriminant and/or coordinate contribution of necrosis and apoptosis to myocardial cell death in the mature and aged male and female, with particular emphasis on the development of novel and specific cardioprotective protocols. Study designs utilize models of stunning and ischemia/reperfusion injury in the isolated Langendorff perfused and the in situ blood perfused heart to determine the relative contribution of these pathways in the aged as compared  to the mature male and female cardiac surgical patient.
