Abstract  This examination of brachial artery (BA) differential characteristic impedance, ΔZ c, illustrates that changes in Z c can occur from changes in either BA wall stiffness (Young’s modulus, E) and/or its diameter, D. Furthermore, we assessed how changes in both E and D...

OBJECTIVES: This randomised trial evaluated if patients with atrial fibrillation (AF) and no history of atrial flutter (AFL) had any benefit of prophylactic cavotricuspid isthmus block (CTIB) in addition to circumferential pulmonary vein ablation (CPVA). METHODS: 149 patients with AF (54%...
- Expression and Role of the Calcium-Sensing Receptor in the Blood Vessel Wall. Molostvov, Guerman; Bland, Rosemary; Zehnder, Daniel // Current Pharmaceutical Biotechnology;Apr2009, Vol. 10 Issue 3, p282
The calcium-sensing receptor (CaSR), which is involved in systemic calcium homeostasis, has also been found to be functionally expressed on cells of the vascular wall. Its activation on perivascular nerves and endothelial cells has been shown to regulate arterial tone, peripheral vascular...
