Increased arterial stiffness is associated with higher levels of aortic wave reflection and aortic blood pressure. Recent evidence suggests a link between muscle sympathetic nerve activity and indices of arterial stiffness. Therefore, the aims of this study were to examine the relationship between resting muscle sympathetic nerve activity and characteristics of aortic pressure wave reflection a...

OBJECTIVES To determine the relation of ambulatory systolic blood pressure to aortic obstruction and more extensive vascular dysfunction, assessed by central aortic, peripheral conduit arterial and resistance vessel function. METHODS 12 adults (5 native, 7 recoarctation) were studied before, and 2 weeks and 6 months after aortic stenting. Systolic blood pressure was measured during normal dai...

Arterial wave reflections (AWRs), an important determinant of cardiac afterload, are increased in hemodialysis patients. However, an association between AWRs and left ventricular hypertrophy has not been established in these subjects. We therefore sought an association between these two parameters in a cross-sectional study of two outpatient hemodialysis populations. AWRs were quantified (augme...

Hartley, Craig J., Anilkumar K. Reddy, Sridhar Madala, Mark L. Entman, Lloyd H. Michael, and George E. Taffet. Noninvasive ultrasonic measurement of arterial wall motion in mice. Am J Physiol Heart Circ Physiol 287: H1426–H1432, 2004; 10.1152/ajpheart. 01185.2003.—Despite the extensive use of genetically altered mice to study cardiovascular physiology and pathology, it remains difficult to quan...

Augmentation is a common complication of primary restless legs syndrome (RLS) during treatment; however, its incidence rate remains unclear.The aim of this study is investigate the rate of augmentation during RLS treatment.We searched 6 databases, including PubMed, OVID, Embase, Wiley citations, Web of Science research platform (including SciELO Citation Index, Medline, KCI Korean Journal Datab...

BACKGROUND The aim of this study was to assess the effects of continuous positive airway pressure (CPAP) on arterial stiffness, central blood pressure, and reflected pulse wave characteristics in patients with severe obstructive sleep apnea (OSA) and stage 2-3 arterial hypertension. METHODS Forty-four patients with hypertension and severe OSA (apnea/hypopnea index > 30) received stepped dose ...

BACKGROUND Vascular dysfunction is highly prevalent if not ubiquitous in patients with hypertension. We compared two different measures of vascular function obtained from digital volume waveforms with measures of ventricular-vascular load derived from 24-hour blood pressure (BP) recordings in patients with hypertension. METHODS Digital pulsatile volume waveforms were captured via plethysmogra...

OBJECTIVES/HYPOTHESIS To evaluate the short-term voice outcomes of vocal fold augmentation using fat compared to calcium hydroxylapatite product Radiesse Voice (Merz Aesthetics). STUDY DESIGN Retrospective study design. METHODS Sixty-six consecutive patients with vocal fold insufficiency were recruited, including the final 33 patients treated with fat and all 33 patients treated with calciu...

BACKGROUND The ambulatory arterial stiffness index (AASI) has been proposed as a novel measure of arterial stiffness and has been prospectively shown to predict stroke and cardiovascular death, but not cardiac death. This index has prompted considerable controversy as to whether it is a true measure of arterial stiffness. OBJECTIVE AND METHODS The present study aimed to examine three differen...
