Regional myocardial perfusion abnormalities on xenon-133 imaging in patients with angina pectoris and normal coronary arteries

With use of semiselective xenon-133 injections and gamma camera recording, myocardial scintigrams were obtained in a series of 20 patients with angina pectoris, abnormal exercise electrocardiograms and normal coronary arteries. Ten patients (Group I) exhibited localized perfusion defects and the oth...

Zusammenfassung:With use of semiselective xenon-133 injections and gamma camera recording, myocardial scintigrams were obtained in a series of 20 patients with angina pectoris, abnormal exercise electrocardiograms and normal coronary arteries. Ten patients (Group I) exhibited localized perfusion defects and the other 10 (Group II) a homogeneous uptake of the tracer. Group I was characterized by more past myocardial infarctions and, most significantly, by male preponderance ( P
