The possible value of myocardial imaging with 201thallium as a screening procedure for the detection of latent disease has not been previously shown. Fifty-eight asymptomatic men underwent exercise 201thallium imaging together with a risk score profile based on the Framingham criteria for predicting future coronary events. Six subjects (10%) developed perfusion defects compatible with myocardial ischemia. The risk score for the population with an abnormal test was 7.7 +/- 2.9%, compared to 2.0 +/- 2.2% (p less than 0.001) for those men with normal tests. Three of the subjects with abnormal scans underwent selective coronary arteriograms; all three had normal coronary arteries. During a 30-month follow-up, all individuals remained physically active and free of cardiac symptoms. Exercise myocardial imaging is not a cost-effective means of detecting coronary artery disease in an asymptomatic population and should not be used as a screening procedure.
