Assessment of Regional Wall Motion in Coronary Artery Disease Using Radionuclide Methods

Abstract

72 patients with CAD, 10 patients with congestive cardiomyopathies and 10 normal subjects were evaluated by radionuclide angiography. Comparison with contrast angiography showed good results for LVEF (r = 0.83). Regional asynergies observed in the radionuclide angiography correlated well with defects in thallium scintigrams. Extent of abnormal wall motion was measured and compared with normals, appreciating the deviation from the normal mean radial shortening. Good correlation could be demonstrated with radionuclide ventriculography. In 80% of congestive cardiomyopathies the right ventricle wall became visible in the thallium scintigram.

“…Merx (39) drew attention however to the association of raised right ventricular end-diastolic pressure and low left ventricular filling pressure as an index of right ventricular infarction. Bussmann (37) was able to relate angiographically demonstrated right coronary artery disease with disturbance of right ventricular function but others did not confirm this (36,38). The great difficulties in making valid measurements of right ventricular volume and performance were critically examined (34,37).…”
