Abstract:
We performed the same day dipyridamole stress/rest myocardial SPECT in 14 healthy young men, reconstructed the polar maps according to Cedars-Sinal method and quantitated the radioactivity of myocardial wall. We divided the whole myocardium to 9 sectors. The latero-anterior wall contains the highest count. The infero-septal wall contains the lowest count. There isn't any significant differences of radioactivity in each segment between stress and rest polar map. The hemodynamic parameters after dipyridamole injection in the subjects were significantly changed except systolic blood pressure : the heart rate was increased and diastolic blood pressure was decreased. Adverse effects were reported in 85.7%. We suggest that these data can be used to dectect perfusion defect in the coromary artery disease.
