This case shows the improvement promoted by cardiac resynchronization therapy (CRT) on myocardial perfusion and left ventricular (LV) performance assessed by gated myocardial perfusion scintigraphy. The patient had idiopathic dilated cardiomyopathy, left bundle branch block and severe heart failure despite optimized medical treatment. After CRT, clinical improvement, QRS reduction and improveme...

Currently, myocardial TI-201 scintigraphy is most often performed in conjunction with exercise stress testing in patients with suspected or known CAD. Stress thallium tests were performed for 156 patients with and without old myocardial infarctions complaining of chest pain. All of them underwent contrast coronary angiography. Perfusion defects were mostly manifested as reversible defects ...

INTRODUCTION Myocardial reperfusion during the course of an acute myocardial infarction improves patients' short- and long-term prognosis; coronary blood flow is successfully re-established while preserving a large amount of at-risk muscle. Clinical evolution, however, varies. Presence of residual ischemia or viable myocardial tissue affects a patient's prognosis. Assessment by noninvasive meth...

Methods Thirteen CSX patients (64 ± 12SD years, 9 females), here defined as a history of chest pain and pathological ECG reaction during stress (> 1 mm ST-depression at stress or after 4 minutes of recovery) but normal myocardial perfusion assessed by myocardial perfusion scintigraphy (SPECT), were included. In addition, 15 positive controls (66 ± 9SD years, 6 females) with stress-induced perfu...

OBJECTIVE To evaluate the usefulness of myocardial perfusion scintigraphy (MIBI-SPECT) as a diagnostic tool in well trained men. DESIGN The study was prospective, involving 2 d stress-rest myocardial scintigraphy (MIBI-SPECT), polar map reconstruction with and without uniform attenuation correction, and comparison with a healthy male group (local Swedish) and with a commonly used reference gr...

Background Obesity is an emerging population at high risk for cardiac events for which robust stress imaging techniques are necessary. Stress-perfusion CMR has high image resolution and is less affected by tissue attenuation compared to nuclear scintigraphy. However, its prognostic value in obese patients has not been determined. We hypothesized that stress-perfusion CMR can effectively prognos...

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 ...

Introduction: The aim of this study was to evaluate the effect of successful kidney transplantation (KT) on myocardial perfusion and left ventricular function by both qualitative (visual) interpretation and semiquantitative parameters, using myocardial perfusion scintigraphy with gated-single photon emission computed tomography (gated-SPECT) in patients suffering from end-stage renal disease.
