Assessment of left-ventricular function by radionuclide ventriculography for the diagnosis of coronary heart disease

Radionuclide (99mTc) ventriculography demonstrated a tendency to reduced ejection fraction, mean normalized systolic expulsion rate and myocardial circular fibre shortening rate of coronary patients that was proportionate to the severity of their condition. Myocardial lesion was shown to be heterogenous and typically involve asynergic areas. As the disease progresses, the disturbance of myocardial contractility grows more severe, and the number of hypokinetic areas increases while that of normo- and hyper-kinetic areas declines
