BACKGROUND Pressure-induced left ventricular hypertrophy is one of the mechanisms responsible for an impaired coronary vasodilating capacity leading to myocardial ischemia and angina. The aim of the study was to investigate myocardial perfusion using cardiovascular magnetic resonance in patients with arterial hypertension and a history of chest pain and normal coronary angiography, and to estim...

AIMS The microvasculature damage after myocardial infarction has important implications. The hypothesis of the study was that wall motion abnormalities and microcirculation status do not necessarily match after myocardial infarction, and therefore the study of only myocardial wall motion could offer an incomplete evaluation in these patients. METHODS Wall motion and myocardial perfusion asses...

Left ventricular (LV) function and volumes, along with myocardial perfusion, have major diagnostic and prognostic importance inpatients with coronary artery disease [4,11,13,14, 18,20,27]. Myocardial perfusion scintigraphy is a well-established technique for evaluation of myocardial perfusion [16,26,37,38]. Electro cardiographic gating during the acquisition of SPECT perfusion images has become...

AIM To measure the prevalence of abnormal rest perfusion in a population of consecutive patients with known hypertrophic cardiomyopathy (HCM) referred for cardiovascular MRI (CMR), and to assess any associations between abnormal rest perfusion and the presence, pattern, and severity of myocardial scar and the presence of risk factors for sudden death. MATERIALS AND METHODS Eighty consecutive ...

Objective: Although coronary artery disease (CAD) is the leading cause of death in type 2 diabetic patients, it is frequently asymptomatic. Myocardial perfusion imaging (MPI) is reported to show ischemia in a significant number of asymptomatic diabetic patients. We studied the prevalence and severity of myocardial perfusion defects in asymptomatic diabetic patients and its clinical impact. Meth...

Antianginal and lipid-lowering medications may modify the results of stress myocardial perfusion imaging. Several studies have shown the beneficial potential of these agents in suppressing myocardial ischemia in patients with known coronary artery disease. The effects of nitrates, calcium-channel blockers, beta-blockers, and statins on myocardial perfusion imaging are likely attributable to cha...

objective: iqspect is an advanced high-speed spect modality for performing myocardial perfusion imaging (mpi), which uses a multi-focus fan beam collimator with resolution recovery reconstruction. the aim of this study was to compare iqspect compared with conventional spect interms of performance based on standard clinical protocols. in addition, we examined the concordance between conventional...

objective: the risk of cardiac death in diabetic patients is 3 times more than non-diabetics. but it is not determined who need cardiac screening. about 41% of diabetic patients with silent ischemia are missed. the carotid intima-media thickness (cimt) and ankel brachial index are two independent,simple and non invasive method in vascular complications diagnosis in diabetic patients.the aim of ...
