The effects of isoproterenol and dopamine on regional myocardial blood flow were studied in 10 open-chest dogs after acute stenosis of the proximal circumflex coronary artery. Blood flow was determined by the radioactive microsphere technique. Isoproterenol led to a homogenous increase in blood flow in the normal myocardium. In the myocardium with compromised coronary blood flow, isoproterenol led to a relative subendocardial ischemia. This occurred despite increased aortic flow and peak left ventricular dp/dt. Dopamine also increased aortic flow and peak left ventricular dp/dt, but it did not cause regional myocardial ischemia. The findings suggest that dopamine is the preferable inotropic agent in managing low cardiac output in patients with significant coronary artery disease.
