Twenty two patients with a history of acute myocardial infarction underwent pulmonary perfusion scintigraphy at rest and during bicycle exercise testing. 99mTc-labelled human albumin microspheres were used. The perfusion ratio in the upper and lower pulmonary regions (U/L ratio) was calculated from scintigraphic findings. There was a close correlation between mean pulmonary blood pressure and U/L ratio (r = 0.95). It was established that the absence of microcirculatory bed reserve scintigraphically revealed in the lesser circulation in patients with prior myocardial infarction may be considered to be a negative predicator.
