Drugs for Heart Test: Chemical stress tests are used to diagnose heart artery blockage in people who cannot treadmill exercise. Persantine is injected IV and dilates normal blood vessels more than abnormal ones causing an ischemic defect on a nuclear image. Dobutamine is injected IV and increases the heart rate and contractility with muscle fed by a blocked artery not responding as well as normal muscle.

Very: Persantin-dipyridamole is a vasodilation inducer and some anti platelet activity doubt amine has some vasodilation and cardiac stimulating effects both are used to test the heart for ischemia -stress particularly if one cannot do the treadmill due to ?Arthritis PVD etc.
