Introduction: Radiation-induced cardiovascular damage is a potential side effect of radiation therapy in patients with left-sided breast cancer. This prospective study compares the severity and reversibility of perfusion and functional abnormalities before, and six months after, 3D-Conformal radiation therapy treatment in left-side breast cancer patients with conventional and h...

The assessment of myocardial perfusion by nuclear scintigraphy is an important diagnostic tool for the evaluation of patients with ischemic heart disease. Although a variety of radiopharmaceuticals have been used to assess coronary blood flow, thallium-201 ( 01 Tl) has become the most commonly used imaging agent since its introduction for clinical use by Lebowitz eta!. in 1973 (J). Thallium-20 ...

OBJECTIVES to determine the prevalence of asymptomatic ischemic heart disease (IHD) in HIV patients by myocardial perfusion scintigraphy (MPS) and to determine the value of coronary artery calcium score (CACS), carotid intima-media thickness (cIMT) and pericardial fat volume as screening tools for detection of IHD in subjects with HIV. BACKGROUND Patients with HIV seem prone to early developm...

introduction: we aimed to investigate the effect of right bundle branch block (rbbb) on perfusion and functional parameters in dipyridamole stress/rest tc99m-mibi gated myocardial perfusion spect (gspect) which may be helpful in interpretation of myocardial perfusion imaging. methods: we studied 73 patients with low pre-test likelihood of coronary artery disease in two groups:  38 patients with...

BACKGROUND The cardiovascular disease is the main cause of death among diabetic patients, which makes it crucial to identify the individuals at higher risk of cardiovascular events. OBJECTIVE To evaluate the prognostic value of scintigraphy with gated single photon emission computed tomography (SPECT) in patients with diabetes mellitus (DM) and suspected coronary artery disease. METHODS Ret...

Introduction: To assess if myocardial ischemia evidenced through both perfusion abnormalities and post-stress left ventricular ejection fraction reduction by gated single photon emission tomography (SPECT) myocardial scintigraphy in women with angina and normal coronary angiograms, as well as the presence of endothelial dysfunction, can predict cardiac events during a medium term follow-up. Met...

OBJECTIVES Although different noninvasive tests have been proposed for detecting coronary artery disease (CAD) in patients with hypertension and chest pain symptoms, the relative performance of the available techniques has not been systematically assessed. BACKGROUND Patients with hypertension frequently complain of chest pain and exhibit ischemic-like ST segment changes on the exercise elect...

INTRODUCTION AND OBJECTIVES In everyday clinical practice, the cardiologist needs to integrate anatomical and functional information from patients with coronary artery disease. The aim of this study is to present a way to unify, in three-dimensional images, anatomical information from coronary angiography with physiological information from myocardial perfusion scintigraphy. METHODS Three pat...
