Hypertension, diabetes, and hypercholesterolemia are characterized by a reduction in arterial distensibility and by accelerated atherosclerosis. Whether arterial stiffening is an inherent feature of these conditions or just the consequence of the atherosclerotic clinical or subclinical lesions is not known, however. Our aim was to obtain information on this issue by directly measuring, in human...

Estrogen administration has a number of favorable cardiovascular effects, and recent evidence suggests that these include an increase in arterial distensibility. Whether this is also the case for the physiological changes in estrogen production during the menstrual cycle has never been determined, however. In 21 premenopausal healthy women, we continuously measured radial artery diameter and bl...

BACKGROUND Aortic distensibility is an elasticity index of the aorta, and reflects aortic stiffness. Coronary artery disease has been found to be substantially associated with increased aortic stiffness. In this study we aimed to retrospectively analyze the association of angiographically determined aortic distensibility with the patency rates of coronary bypass grafts METHODS The study was c...

Elastin is a protein of the extracellular matrix that forms the major component of elastic fibers from the arterial wall thickness and plays an important role in elastic properties of large blood vessels. To study the relationships between the Ser422Gly polymorphism in exon 16 of the gene-encoding elastin and the distensibility of 2 different arteries, the radial artery (a muscular artery) and ...

TO THE EDITOR: We thank the author for his interest in our manuscript. During the transoral incisionless fundoplication (TIF) procedure, a retractor is anchored at the esophagogastric junction (EGJ) after which tension is applied to advance the EGJ caudally. Therefore, we agree that lengthening of the EGJ is a substantial mode of action of the TIF procedure. In addition, transmural placement of...

The classical cardiovascular risk factors explain only a part of the increased macrovascular disease in subjects with type 2 diabetes (1). Reduction of the elastic properties of the aorta is an early marker of atherosclerosis, and it is diagnosed early in the course of type 2 diabetes (2). The detrimental effects of the classical risk factors on aortic distensibility are well known. However, th...

Physical exercise is considered to be beneficial for cardiovascular health. Nevertheless, the underlying specific molecular mechanisms still remain unexplored. In this study, we aimed to investigate the effects of voluntary exercise on vascular mechanical properties and gene regulation patterns in spontaneously hypertensive rats. By using ultrasound biomicroscopy in an ex vivo perfusion chamber...
