it is of value to determine the amount of viable myocardial tissue in patients suffering from chronic coronary artery disease and ventricular dysfunction. having the capability of evaluating both myocardial perfusion and function, simultaneously, myocardial scanning by ecg-gated is an appropriate method for this purpose. the aim of this study was to compare the results of myocardial perfusion a...

AIM To determine the prognostic value of reversible myocardial perfusion defects on myocardial perfusion scintigraphy (MPS) in patients with type 2 diabetes mellitus and mild anginal complaints. METHODS AND RESULTS In the MERIDIAN trial, patients with diabetes mellitus type 2, stable, mild anginal symptoms (Canadian Cardiovascular Society classification (CCS) I-II/IV) and reversible perfusion...

Introduction: In patients with coronary artery disease (CAD) noninvasive evaluation for detection of ischemia is important to avoid invasive interventions like angiography. Exercise stress test is conventionally the first study used in evaluation of CAD. Considering the noninvasive nature of the myocardial perfusion scan, we decided to compare its accuracy with stress test. Methods: Patie...

Despite the evidence in experimental animal models that insulin, or GIK (glucose-insulin-potassium), improves left ventricular function and perfusion during both acute and chronic ischaemia, clinical studies have generated conflicting results. We tested the hypothesis that pretreatment with GIK attenuates the vascular and functional effects of stress-induced myocardial ischaemia in humans. Twen...

statement of the problem periodontitis is a common infectious disease that can be affected by different factors.periodontal conditions can be influenced by systemic diseases and they also can act as risk factors for some systemic diseases. several studies have been carried out on the relationship between cardiovascular disease and periodontal disease. purpose the purpose of our study was to eva...

different software tools for quantification of myocardial perfusion spect (mps) studies are routinely used. several perfusion parameters can be computed automatically.  interpretation of the mps should start with visual inspection of the rotating planar images, visual analysis of reconstructed spect slices and then quantitative analysis to confirm the visual impression. quantification should be...

BACKGROUND Spinal cord stimulation (SCS) and percutaneous myocardial laser revascularisation (PMR) are treatment modalities used to treat refractory angina pectoris, with the major aim of such treatment being the relief of disabling symptoms. This study compared the change in myocardial perfusion following SCS and PMR treatment. METHODS Subjects with Canadian Cardiovascular Society class 3/4 ...
