BACKGROUND Use of upper-arm arterial occlusion to induce reactive hyperemia, and endothelium-dependent flow-mediated dilation (FMD) of the brachial artery, induces greater conduit vessel dilatation than lower-arm occlusion. However, brachial artery ischemia after upper arm arterial occlusion may make this approach unreliable. We studied whether upper or lower arm occlusions differ in their abil...

Noninvasive in situ evaluations of pulsatile changes of blood pressure and arterial diameter were performed at the sites of the common carotid and femoral arteries in a population of 78 untreated normotensive and hypertensive subjects. Arterial segments were studied by using an original echo-tracking technique for internal diameter and validated applanation tonometry for local pulse pressure me...

OBJECTIVES We tested whether long-term administration of antioxidant vitamins C and E improves coronary and brachial artery endothelial function in patients with coronary artery disease (CAD). BACKGROUND Endothelial function is a sensitive indicator of vascular health. Oxidant stress and oxidized low-density lipoprotein (LDL) impair endothelial function by reducing nitric oxide bioavailabilit...

background: given the lack of consistency in the literature regarding the reliability of the ankle-brachial index (abi) as a valid screening tool and an independent risk indicator of cardiovascular events and mortality, we compared it with angiography as a reference standard test. methods: this case-control study, conducted between 2010 and 2011 in tehran heart center, recruited 362 angiographi...

Background: The radial artery is an essential artery supplying the structures in the forearm. Variations in the radial artery concerning its origin, course, branching pattern, and mode of termination have been commonly reported. The high origin of the radial artery from either brachial or axillary artery was detected in numerous studies. Clinically-radial artery is used in cardiac catheterizati...

Dear Editor, True aneurysm of brachial artery, just distal to axillary artery, is relatively rare. Moreover, this type of aneurysm following usage of axillary crutch has not reported in the literature. Furthermore, this entity presenting as Reynaud’s disease has not been described; though microemboli following subclavio-axillary artery aneurysm (arterial thoracic outlet syndrome) is well-define...

Study population The study population comprised a hypothetical cohort of previously untreated 60-year-old patients presenting with severe unilateral claudication of at least one year in duration, who had at least one significant lesion (>50% arterial diameter reduction) that was located predominantly suprainguinal or infrainguinal, an ankle brachial index pressure of 0.70 and no history of coro...

Previous studies have established effects of exercise training on arterial wall thickness, remodeling, and function in humans, but the extent to which these changes are locally or systemically mediated is unclear. We examined the brachial arteries of the dominant (D) and nondominant (ND) upper limbs of elite racquet sportsmen and compared them to those of matched healthy inactive controls. Caro...
