Abstract

A study was made of 24 patients with coronary disease and visible apical dyskinesis, 15 patients with diffuse cardiomyopathy, and 40 normal subjects. Regional and global time-activity curves were derived from radionuclide ventriculograms. Various parameters extracted from these TACs were tested for significant differences between the groups. Some regional parameters (e. g. ejection fraction) correlated highly with the global value and failed to give additional regional information. Twelve of the 70 parameters studied showed potential for separating groups. Best results were obtained with global ejection fraction, regional emptying time, phase, asynchrony, and filling fraction. The results suggest that combinations of parameters could be effective in distinguishing regional abnormal cases from normal or diffusely abnormal groups.
