Carvedilol treatment in patients with heart failure results in a 57% decrease in myocardial FFA use without a significant change in glucose use. These metabolic changes could contribute to the observed improvements in energy efficiency seen in patients with heart failure.

Perfusion abnormalities are demonstrated by means of Cu-62-PTSM PET in 91% of patients with occlusive coronary artery disease seen at the time of cardiac catheterization, and it shows an excellent normalcy rate of 100%.

Apical hypertrophic cardiomyopathy, common in Japan, is characterized by a spade-like configuration of the left ventricle on contrast angiography. The condition is identified by giant negative T waves in the precordial echocardiographic leads, no intraventricular pressure gradient, and mild symptoms.
