Acetate-induced changes in cardiac energy metabolism and hemodynamics in the rat.

abstract：BACKGROUND:Reopening of the infarct-related coronary artery is the treatment of choice in the clinical setting of acute myocardial infarction. Nevertheless the removal of the total occlusion obtained either by thrombolysis or by primary angioplasty is followed by the ischemia/reperfusion sequelae. One of many proposed ...
