MacDonald] Although dipyridamole can be used with myocardial scintigraphy to demonstrate reversible perfusion defects, combining exercise with the pharmacologic tool could improve image quality and information yield. The incidence of perfusion defects and the quality of thallium 201 images were reviewed in a series of 820 patients who had been assigned to a specific stress-test mode. Supine bicycle exercise alone was used (group 1) where no pharmacologic or physical factors (e.g., beta-blockers, arthritis) limited performance; otherwise, intravenous dipyridamole was followed by symptom-limited exercise (group II). Angiographic correlation was available in 57 patients in group I, and in 158 in group II; of these, 109 performed significant exercise (≥ 3 min at increasing workloads) following dipyridamole (group II A), whereas in 49 (group IIB) the exercise phase following dipyridamole was truncated. All test-mode groups were similar with respect to the incidence of ST segment depression during testing, patient throughput, and the sensitivity of perfusion defects. Chest pain and reversible defects were induced more frequently in group II than in group I. In group II A, splanchnic background activity was lower (P < 0.001) than in group II B, and the false-positive rate tended to be lower. Thus, combining exercise with dipyridamole in patients with non-cardiac limitations to exercise enabled the achievement of optimal results for perfusion scintigraphy.
