Cardiopulmonary Bypass in Revascularization and Fluid Management of Exercise-induced Acute Myocardial Infarction

A 52-year-old man was resuscitated from a cardiac arrest during a marathon run. During initial evaluation, he received a significant amount of crystalloid fluid to maintain end-organ perfusion. Based on electrocardiogram findings, myocardial infarction was suspected and an angiogram was performed. An acute thrombosis of the left anterior descending vessel was noted, angioplastied, and stented. Given that he was in cardiogenic shock, acidotic, and hemodynamically labile, an emergent coronary artery bypass grafting with cardiopulmonary bypass was performed to simultaneously revascularize the myocardium and remove intravascular fluid.
