Osteoarthritis (OA) and cardiovascular diseases (CVD) are prevalent conditions and often co-exist. Vascular involvement in pathogenesis of CVD and OA gives reason to investigate arterial stiffness in OA. The aim of this study is to investigate the associations between OA and arterial stiffness.
Arterial...

Background: Affective temperaments (anxious, depressive, cyclothymic, irritable and hyperthymic) are subclinical manifestations of major mood disorders and there is cumulating evidence about their involvement is somatic disorders as well. The aim of our study was to evaluate the associations of affective...

Central systolic blood pressure (cSBP) could be helpful to monitor hypotension during dialysis. However most cSBP devices are based on peripheral estimates which might be unreliable during the specific hemodynamic state of dialysis. Complior Analyse (Alam Medical, France) presents the advantage of measuring...

Background: The purpose of this study was to evaluate the relationship between the breath-holding duration and the sensitivity of the arterial baroreflex, as well as the prognostic value of the breath-holding test in the assessment of decreased baroreflex sensitivity (BRS) in patients with chronic heart...

During 19th century the term “cardiolith” was widely used to describe a cluster of cardiac entities that could cause sudden death. Blood clots, polypoid growths, microorganisms and inflammation were implicated. Scientists of the era described formations that could enter any heart chamber after having...

The carotid bisferiens pulse and the radial water hammer pulse are typical of severe chronic aortic regurgitation. Little is known about the mechanism of these classic cardiovascular signs identified on physical examination. We report the first characterization of these abnormal pulse patterns using...

Introduction: Common carotid artery (CCA) intima-media thickness (IMT), lumen diameter, and maximum plaque thickness were assessed on ultrasound images. The objective of the study was to evaluate the intra- and inter-reader reproducibility of the measurements following a standardised protocol.
Methods:...

Background: Early return of reflected blood pressure (BP) waves from the lower body augments central systolic BP and increases systolic pressure-time index (SPTI) and wasted left ventricular (LV) pressure energy, which increase afterload and myocardial oxygen (MVO2) demand. Accordingly, we sought to...

Symptoms are only the tip of the iceberg in atherosclerotic disease. Beneath the surface are multiple patho-physiological processes taking place in and around the vessel wall. The increasing knowledge in the field of vascular biology also reveals new imaging targets as biological markers of the disease....

With the help of both clinical and genetic diagnostic tools, the spectrum of inherited disorders affecting the arterial system has extended tremendously over the past decades. Discriminating these different entities is important since prognosis and treatment may differ substantially according to the...
