OBJECTIVES: The current study addressed the hypothesis that the local decrease in endothelin-1 (ET-1) bioavailability during sustained flow increases contributes to endothelium-dependent, flow-mediated dilatation (FMD) of conduit arteries and is altered in presence of cardiovascular risk factors. METHODS AND RESULTS: In nine young healthy individuals, the decrease in local ET-1 plasma levels and radial artery FMD in response to hand skin heating (from 34 to 44 °C) was not affected by endothelin type A (ETA) receptor blockade, achieved using the brachial infusion of BQ-123 (100 nmol/min per l of forearm), as compared with physiological saline (0...

We report on the fully percutaneous insertion and removal of the Impella 5.0 microaxial flow device via the axillary artery in a patient with cardiogenic shock and peripheral artery disease. Due to inadequate iliofemoral vasculature and desire for mobility, the axillary artery was felt to be the most appropriate access approach for temporary mechanical circulatory support. The procedure was well tolerated and the patient was supported for 17 days, at which time the device was safely removed in a fully percutaneous manner at the time of permanent left ventricular assist device placement...

OBJECTIVES: To investigate the feasibility and image quality of low-dose contrast computed tomography (CT) angiography with pulmonary artery (PA) protocol. BACKGROUND: Aortic stenosis is the most common valvular heart disease and transcatheter aortic valve replacement (TAVR) has evolved as an alternative method for surgical valve replacement in intermediate-risk and high-risk surgical patients. CT is essential for measurement of aortic annulus prior to TAVR. METHODS: Twenty patients underwent a low-dose contrast study with PA protocol and 20 patients underwent a traditional-dose study (traditional protocol)...

Radiation therapy is one of the most important methods for the treatment of malignant tumors. However, in radiotherapy for thoracic tumors such as breast cancer, lung cancer, esophageal cancer, and mediastinal lymphoma, the heart, located in the mediastinum, is inevitably affected by the irradiation, leading to pericardial disease, myocardial fibrosis, coronary artery disease, valvular lesions, and cardiac conduction system injury, which are considered radiation-induced heart diseases. Delayed cardiac injury especially myocardial fibrosis is more prominent, and its incidence is as high as 20–80%...

Prenatal iron-deficiency (ID) is known to alter fetal developmental trajectories, which predisposes the offspring to chronic disease in later life, although the underlying mechanisms remain unclear. Here, we sought to determine whether varying degrees of maternal anaemia could induce organ-specific patterns of hypoxia in the fetuses. Pregnant female Sprague Dawley rats were fed iron-restricted or iron-replete diets to induce a state of moderate (M-ID) or severe ID (S-ID) alongside respective controls. Ultrasound biomicroscopy was performed on gestational day (GD)20 to assess uterine and umbilical artery blood flow patterns...

The cardio-ankle vascular index (CAVI) represents a promising index of arterial stiffness. However, neither the CAVI measure nor its measurement device, the VaSera, have undergone general testing in a North American clinical setting. To begin the process of collecting normal values in the United States, we studied 20 male and 28 female volunteers without reported cardiovascular or renal disease and no history of smoking. Their CAVIs, ankle-brachial indices (ABIs), and four-limb blood pressures were measured in three positions: supine, 7° Trendelenburg, and 7° reverse Trendelenburg...

INTRODUCTION: Patent foramen ovale (PFO) is associated with cryptogenic stroke (CS) and migraine with aura (MA). Endothelial dysfunction (ED) is a risk factor for development of cardiovascular disease, but might also be involved in migraine pathophysiology. Short-term worsening of migraine has been described after closure of PFO. We evaluated endothelial function in patients with CS and PFO, before and after closure of PFO, and in patients with migraine, whether changes in endothelial function was related to a change in migraine frequency...
