Coronary blood flow, myocardial oxygen consumption, and myocardial metabolism in normal and hyperthyroid human subjects.
The effects of thyroid hormone excess on myocardial hemodynamics and carbohydrate metabolism were determined in a group of subjects, and the findings compared with those obtained in a group of normal individuals. The results indicate that in thyrotoxicosis there tends to be an increase in coronary blood flow and myocardial oxygen consumption and a normal per cent extraction of oxygen by the myo...
متن کاملHemodynamics, coronary blood flow, and myocardial metabolism in coronary shock; response of 1-norepinephrine and isoproterenol.
Hemodynamics and myocardial metabolism were evaluated in 18 patients in cardiogenic shock following acute myocardial infarction. The response to l-norepinephrine was studied in seven cases and the response to isoproterenol in four cases. Cardiac index (CI) was markedly reduced, averaging 1.35 liters/min per m(2). Mean arterial pressure ranged from 40 to 65 mm Hg while systemic vascular resistan...

متن کاملCoronary Flow, Ventricular Function, and Myocardial Metabolism
To evaluate coronary flow reserve during cardiac catheterization, intracoronary adenosine and papaverine have been used in the clinical setting. Although papaverine maximizes coronary blood flow, it induces several toxic side effects that reduce its desirability as a coronary dilator. This investigation was designed to compare the subselective intracoronary administration of papaverine with tha...
متن کاملEvaluation of Myocardial Blood Flow and Metabolism
Measurement of myocardial blood flow for research studies and in clinical practice has enhanced our understanding of the coronary circulation in health and disease. Despite the refinements in measurement techniques of epicardial coronary anatomy provided by quantitative angiographic techniques and, more recently, by intravascular ultrasound, direct measurement of coronary blood flow provides im...
