The purpose of this study was to evaluate the long-term prognostic value of exercise technetium-99m methoxyisobutylisonitrile (99mTc-MIBI) single-photon emission tomography (SPET) imaging in patients after percutaneous coronary intervention (PCI). Three hundred and eighteen consecutive post-PCI patients who underwent exercise and rest 99mTc-MIBI SPET(More)
We compared technetium-99m methoxyisobutylisonitrile (MIBI) myocardial perfusion single-photon emission tomography (SPET) (MPS) and electron beam computed tomography (EBCT) in order to assess their respective value in the detection of coronary artery disease (CAD).99mTc-MIBI SPET (stress-resting) and EBCT studies were performed in 51 patients with suspected(More)
BACKGROUND Myocardial bridging (MB) is a common, congenital coronary-abnormality that is found on average in one out of every three adults at autopsy (Moehlenkamp et al in Circulation, 106:2616-2622, 2002; Erbel et al in Circulation, 120:357-359, 2009). However, its clinical significance and impact on myocardial ischemia remains controversial and unclear.(More)
OBJECTIVE To investigate the effects of higeramine (HG) on hemodynamics and its tolerability and safety so as to see if it can be used in cardiac loading test, and to compare the hemodynamic effects of HG and dobutamine (DB). METHODS Six dogs were infused intrevenously with HG in escalating doses from l microgram/kg/min through 2 microgram/kg/min and to 4(More)
OBJECTIVE The purpose of this study was to evaluate the relation between deep venous thrombosis (DVT) and pulmonary thromboembolism (PTE) by radionuclide imaging. METHODS One hundred forty patients with PTE from September 1997 to March 2001 at this institution was confirmed by clinical manifestation, pulmonary perfusion (PPI)/ventilation scan (PPV) and(More)
PURPOSE The gold standard for assessing the degree of pulmonary hypertension is by right ventricular catheterization, an invasive procedure. This study was carried out to evaluate a noninvasive method using dynamic pulmonary perfusion imaging (DPPI) for assessing pulmonary hypertension and surgical outcome in patients with valvular heart disease. METHODS(More)
99mTc-CPI myocardial perfusion scintigraphy including planar images in 35 patients and SPECT images in 16 patients has been studied. Scintigraphic data revealed that high quality 99mTc-CPI myocardial perfusion images were obtained. The sensitivity and specificity of 99mTc-CPI planar images in detecting CAD was 92% and 80% respectively. There was no(More)
Objective Dilated cardiomyopathy (DCM) is generally considered to be accompanied by both left and right ventricular dysfunction, but most studies only analyze the left ventricular function. In this study, we evaluated the effect of arotinolol on right ventricular function in patients with DCM. Methods Right ventricular ejection fraction (RVEF) and right(More)
