Comparison of gated radionuclide scans and chest radiographs. Assessment of left ventricular impairment in patients with coronary disease

JA Bianco, DB Reinke, DG Makey and RB Shafer

Diagnostic efficacy of gated cardiac blood pool imaging was studied in 41 consecutive patients with LV ejection fractions (LVEF) less than or equal to 0.50. Eighty percent of patients were receiving therapy for LV failure at the time of the study. All patients had documented coronary- artery disease (CAD). Chest x-ray films were interpreted blindly by a senior radiologist. Cardiothoracic ratio of less than or equal to 0.50 was recorded as normal. Radionuclide assessment of LV function contributes importantly to the diagnostic and screening value of chest x-ray films. Patients with coronary disease and clinical evidence of heart failure should have radioisotopic studies even if chest x-ray film findings are normal. In patients with coronary artery disease and enlarged LV on chest films, radionuclide study of left ventricular performance aids in defining LV impairment, and in the prognostication of subsequent clinical course.
