Thirteen patients with Prinzmetal's variant angina performed treadmill exercise tests in the early morning and afternoon of same day. The attacks ST elevation were induced repeatedly all 13 morning, but only two afternoon. Propranolol did not suppress exercise-induced patients. Diltiazem suppressed phentolamine eight nine Coronary arteriograms demonstrated that spasm occluding completely or almost large coronary artery supplying area myocardium showing appeared during disappeared along after...
Two hundred forty-five patients with variant angina were followed for an average of 80.5 months (range, 36-184 months). Survival rate at 1, 3, 5, and 10 years was 98%, 97%, 93%, respectively. without myocardial infarction 86%, 85%, 83%, 81%, By univarite analysis, ST segment elevation in both the anterior inferior electrocardiographic leads most important factor influencing survival, by use calcium antagonists, left ventricular function, smoking, alcohol intake. The variables that...
Vigorous hyperventilation was induced for five minutes immediately after a five-minute infusion of 100 ml Tris-buffer (pH 10) in nine patients with Prinzmetal's variant angina. In eight the patients, chest pain ischemic changes electrocardiogram occurred during this procedure or within it ended. Coronary arterial spasm appeared and disappeared administration nitroglycerin all four whom coronary cinearteriography performed. This evident both before sublingual (0.6 mg). The oral 90 mg...
We investigated possible correlations between apparent diffusion coefficient (ADC) values and prognostic factors of breast cancer.We retrospectively evaluated 81 patients who underwent magnetic resonance (MR) imaging the were diagnosed pathologically with invasive ductal carcinoma (IDC) not otherwise specified foci one cm or larger. excluded in situ IDC smaller than because small lesions decrease reliability signal intensity diffusion-weighted (DWI). also special type cancers. used t-test to...
Assessment of hemodynamic changes in ischemic cardiac segments at rest using CT has yet to be performed. We hypothesized that variations subendocardial perfusion during the cycle might related appearances ischemia. The purpose this study was investigate myocardial contrast-enhanced 64-MDCT.We performed MDCT and stress/rest (201)Tl scintigraphy (MPS) 34 patients with suspected coronary artery disease. reconstructed 2D long- short-axis images diastolic systolic phases raw data from...
Background: The purpose is to investigate the ability of 64-slice multidetector computed tomography (MDCT) at rest in detecting myocardial ischemia, conventionally depicted by perfusion scintigraphy (MPS). Methods and Results: In 75 patients with suspected coronary artery disease, cardiac CE-MDCT stress/rest MPS were performed. 2D images reconstructed diastolic systolic phases using raw data from (CT) angiography. CT numbers myocardium used as an estimate enhancement. was shown a color scale...
We attempted to assess coronary artery flow using adenosine-stress and dual-energy mode with dual-source CT (DE-CT). Data of 18 patients suspected arteries disease who had undergone cardiac DE-CT were retrospectively analyzed. The divided into two groups: 10 performed adenosine stress CT, 8 rest as controls. reconstructed an iodine map composite images at 120 kV (120 images) raw data scan parameters 100 140 kV. measured mean attenuation in the proximal distal portion on both images. Coronary...
The purpose of this study was to quantify myocardial strain on the subendocardial and epicardial layers left ventricle (LV) using tagged cardiovascular magnetic resonance (CMR) investigate transmural degree contractile impairment in chronic ischemic myocardium. 3T CMR performed at rest 12 patients with severe coronary artery disease who had been scheduled for bypass grafting. Circumferential (C-strain) end-systole measured short-axis images LV available software (Intag; Osirix). segment...
