RATIONALE The mechanism of functional restoration by stem cell therapy remains poorly understood. Novel manganese-enhanced MRI and bioluminescence reporter gene imaging were applied to follow myocardial viability and cell engraftment, respectively. Human-placenta-derived amniotic mesenchymal stem cells (AMCs) demonstrate unique immunoregulatory and precardiac properties. In this study, the rest...
Introduction: QT interval represents duration of ventricular electrical systole, i.e., the time required for completion of both ventricular depolarization and repolarization. QT interval duration normally varies between leads on the electrocardiography due to variation of repolarization and re-excitability of different ventricular regions. QT dispersion, defined as the difference between maximu...
purpose: to assess the relationship between the severity of coronary arteries involvement and the extent and pattern of myocardial scars in cardiac magnetic resonance of patients with history of remote myocardial infarction. materials and methods: the cardiac magnetic resonance images of sixty patients with history of remote st segment or non-st segment elevation myocardial infarction were revi...
OBJECTIVE To assess the prevalence of myocardial viability by technetium-99m (Tc-99m)-tetrofosmin/fluorine-18-fluorodeoxyglucose (FDG) single photon emission computed tomography (SPECT) in patients with ischaemic cardiomyopathy. DESIGN A retrospective observational study. SETTING Thoraxcenter Rotterdam (a tertiary referral centre). PATIENTS 104 patients with chronic coronary artery diseas...
To evaluate the relationship between the reversible defect of 123I-15-(p-iodophenyl)-9-(R,S)-methylpentadecanoic acid (9MPA) and residual viability within an infarct-related area, we performed resting single photon emission computed tomography (SPECT) with 9MPA and positron emission tomography (PET) with 18F-deoxyglucose (FDG) and 13N-ammonia (NH3) in 7 patients with prior myocardial infarction...
OBJECTIVES In the Surgical Treatment for Ischemic Heart Failure trial, surgical ventricular reconstruction plus coronary artery bypass surgery was not associated with a reduction in the rate of death or cardiac hospitalization compared with bypass alone. We hypothesized that the absence of viable myocardium identifies patients with coronary artery disease and left ventricular dysfunction who ha...
