Minimizing injuries from acute myocardial infarction

Reperfusion therapy is currently the mainstay treatment of acute myocardial infarction, as it salvages myocardial cells from ischemic cell death. However, abrupt restoration of coronary blood flow induces another type of cell death called “lethal reperfusion injury,”

Death and stroke risks after surgical aortic valve replacement: A real world perspective
