Lung uptake, ventricular cavitary dilation and basal myocardial uptake represent abnormalities that have been associated with @entity741 on stress thallium-201 images, but that are supplementary to the conventional assessment of perfusion distribution. These "supplementary" indicators of @entity63 were related to the coronary distribution of perfusion abnormalities, the results of electrocardiographic stress testing and to the findings on coronary angiography in 73 @entity1 . Forty @entity1 had multivessel @entity301 ; 19 of these had three @entity66 . Perfusion abnormalities were seen in 39 of these 40 @entity1 but were indicative of multivessel @entity301 in only 28 and of three @entity66 in only 6. However, supplementary indicators were present in 33 of 40 @entity1 with multivessel disease and in 15 of 19 with three @entity66 . Furthermore, they were seen in 16 of 22 @entity1 with multivessel disease in whom conventional perfusion abnormalities underestimated the extent of disease, but in only 4 of 12 @entity1 in whom the extent of disease was overestimated. The presence of either perfusion abnormalities in a multivessel distribution or supplementary indicators identified 38 (95%) of 40 @entity1 with multivessel disease. A markedly positive electrocardiographic treadmill test was a less sensitive indicator of multivessel disease, appearing in only 15 of 40 @entity1 . However, it was present in only 4 of 33 @entity1 without multivessel @entity301 and was more specific for that diagnosis than were supplementary scintigraphic indicators (88 versus 67%, p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
