Increased cerebral arterial pulsatility in patients with leukoaraiosis: arterial stiffness enhances transmission of aortic pulsatility.
BACKGROUND AND PURPOSE Arterial stiffening reduces damping of the arterial waveform and hence increases pulsatility of cerebral blood flow, potentially damaging small vessels. In the absence of previous studies in patients with recent transient ischemic attack or stroke, we determined the associations between leukoaraiosis and aortic and middle cerebral artery stiffness and pulsatility. METHO...
متن کاملHomocysteine and pulsatility index of cerebral arteries.
BACKGROUND AND PURPOSE A pulsatility index (PI) represents vascular resistance distal to an examined artery. The purpose of the present study was to evaluate an association between plasma total homocysteine (tHcy) and PIs of the cerebral arteries in patients with ischemic stroke. METHODS Consecutive patients with ischemic stroke referred to a neurovascular ultrasound laboratory were evaluated...
متن کاملAugmentation index and aortic stiffness in bicuspid aortic valve patients with non-dilated proximal aortas
BACKGROUND We compared aortic stiffness, aortic impedance and pressure from wave reflections in the setting of bicuspid aortic valve (BAV) to the tricuspid aortic valve (TAV) in the absence of proximal aortic dilation. We hypothesized BAV is associated with abnormal arterial stiffness. METHODS Ten BAV subjects (47 ± 4 years, 6 male) and 13 TAV subjects (46 ± 4 years, 10 male) without signific...
متن کاملAssociations between augmentation index and severity of atheroma or aortic stiffness of the descending thoracic aorta by transesophageal echocardiography.
BACKGROUND Although the aortic augmentation index (AI) is an attractive tool as an index of the vascular system, the association between radial AI or brachial-ankle pulse wave velocity (PWV) and severity of atheroma or arterial stiffness of the morphological central artery is unclear. METHODS AND RESULTS Severity of atheroma and aortic stiffness of the descending thoracic aorta (DTA) by trans...
متن کاملImpact of Aortic Stiffness Evaluated by Aortic Pulsatility on Fractional Flow Reserve.
BACKGROUND Fractional flow reserve (FFR) is a highly reproducible, accurate and lesion-specific index to indicate inducible ischemia for a particular coronary artery lesion. Invasively measured aortic pulsatility (AP) is an indicator of aortic stiffness. In this study we aimed to evaluate the possible impact of AP in terms of aortic stiffness on FFR measurement. METHODS In this study, we revi...
