We describe the clinical features and results of cardiac catheterization, PET ([13N]ammonia, 18F-fluorodeoxyglucose (FDG)) and SPECT [123I-labeled 15-(p-iodophenyl)-3-R,S-methylpentadecanoic acid (BMIPP)], in a patient with acute myocardial infarction successfully treated with intracoronary thrombolytic therapy. We compared the clinical and(More)
BACKGROUND We investigated whether diffuse coronary vasoconstriction induced by acetylcholine caused myocardial ischemia. METHODS We studied 30 patients (40 coronary arteries) with spontaneous chest pain or equivocal studies on treadmill exercise testing and no significant coronary stenosis or previous myocardial infarction. During the acetylcholine(More)
To examine whether or not a combination of nonpharmacologic provocative tests potentiated the occurrence of coronary spasm, the cold pressor test combined with hyperventilation was studied in 22 consecutive patients with variant angina admitted to our hospital. After a 12-lead electrocardiogram and blood pressure were recorded, the patient was asked to(More)
To evaluate the clinical significance of reverse redistribution (RR) of resting 201Tl single photon emission computed tomography (SPECT) in patients with vasospastic angina (VSA), we performed left ventriculography, coronary angiography and resting 201Tl-SPECT in 22 patients with VSA. Left ventriculography showed abnormal wall motion in 17 of 22 patients(More)
