Abstract
Cardiogenic shock (CS) in acute myocardial infarction, after successful coronary angioplasty, still carries a case fatality rate of 50%. These patients succumb to a systemic metabolic storm, superimposed on extensive myocardial necrosis and stunning. Nitric oxide (NO) overproduction contributes to the pathophysiology of this morbid state. Current data regarding the physiologic effects of NO and nitric oxide synthase (NOS) inhibitors on the cardiovascular system are reviewed. Clinical trials assessing the safety and efficacy of NOS inhibitors in CS are summarized.
