Radial Diastolic Augmentation Index Is a Useful Predictor of Arterial Stiffness
Diastolic augmentation index (DAI), calculated from radial artery pressure waveform, has been associated with the risk of cardiovascular disease. In the present study, we aimed to evaluate whether DAI could be used as a predictor of arterial stiffness and the effect of heart rate (HR) on it.Measurements of anthropometric parameters, blood pressure (BP),Augmentation index (AI) andDAIwere taken i...
متن کاملPeripheral Augmentation Index is Associated With the Ambulatory Arterial Stiffness Index in Patients With Hypertension
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...
متن کاملAmbulatory arterial stiffness index, pulse wave velocity and augmentation index--interchangeable or mutually exclusive measures?
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...
متن کاملFactors associated with increased radial augmentation index in hypertensive individuals.
BACKGROUND Arterial stiffness is a variable predictor of morbidity and mortality and a possible marker of vascular injury. Its non-invasive assessment by radial tonometry and analysis of the augmentation index (r-AI) allows identifying patients exposed to higher cardiovascular risk. OBJECTIVE To analyze the influence of r-AI on clinical-biochemical variables and its influence on the prevalenc...
متن کاملPeripheral augmentation index and wave reflection in the radial artery.
Peripheral Augmentation Index and Wave Reflection in the Radial Artery To the Editor: We were interested to read the recent article by Munir et al1 and congratulate them on making a valuable contribution to the field of pulse wave analysis. They and Payne and Webb, in their accompanying editorial,2 ponder why the late systolic shoulder (SBP2) corresponds so closely with central systolic blood p...
