Assessment of regional wall motion in coronary artery disease using radionuclide methods.
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.
