The effect of blood pressure on pulse wave velocity (PWV) is well established. However, PWV variability with acute hemodynamic changes has not been examined in the clinical setting. The aim of the present study is to investigate the effect of hemodynamic changes on PWV in patients who undergo cardiothoracic surgery. Using data from 25 patients, we determined blood pressure (BP), heart rate (HR), and the left ventricular outflow tract (LVOT) velocity-time integral. By superimposing the radial arterial waveform on the continuous wave Doppler waveform of the LVOT, obtained by transesophageal echo, we were able to determine pulse transit time and to calculate PWV, stroke volume (SV), cardiac output (CO), and systemic vascular resistance (SVR)...

BACKGROUND: In this study, we examined the relative usefulness of serum copeptin levels as a surrogate marker of vasopressin (AVP) in adult polycystic kidney disease (ADPKD) by correlating it with baseline and longitudinal changes in markers of both renal function and common CVD manifestations (hypertensive vascular disease, atherosclerosis and endothelial dysfunction) that accompany the progression of this disease. METHODS: We studied a cohort of young and otherwise healthy ADPKD patients (n = 235) and measured cardiovascular function using flow-mediation dilatation (FMD), carotid intima media thickness (cIMT) and pulse wave velocity (PWV), as well as serum copeptin (commercial ELISA, a stable marker of AVP activity)...

BACKGROUND: Patients with end-stage renal disease (ESRD) are at a high risk of cardiovascular mortality (CVM). In patients with ESRD, arterial stiffness increases at an earlier age when compared to the general population and this contributes to the overall risk of cardiovascular mortality. The main objective of this study was to clarify the interplay between age and cardiovascular alterations in ESRD. METHODS: Prospective, observational cohort study initiated in April 1987 until the end of 1998 with events recorded until the end of the year 2000 at the F...

Remote photoplethysmography (rPPG) imaging is an optical technique to remotely assess the local cutaneous microcirculation. Despite its potential for enabling health-related applications, the current understanding of the outcome images/maps remains incomplete. In this paper, we present a model and supporting experiments confirming the contribution of skin inhomogeneity to the morphology of PPG waveforms. Since rPPG imagers rely on the complex inner-product operator and may combine multiple wavelengths, the derived phase measurements reflect morphological heterogeneity of PPG signals to a larger extent than propagation-related phase differences...

Significant hemodynamic changes ensue with aging, leading to an ever-growing epidemic of hypertension. Alterations in central arterial properties play a major role in these hemodynamic changes. These alterations are characterized by an initial decline in aortic distensibility and an increase of diastolic blood pressure, followed by a sharp increase in pulse wave velocity (PWV), and an increase in pulse pressure (PP) beyond the sixth decade. However, the trajectories of PWV and PP diverge with advancing age...

Different methods can be used to diagnose early pre-clinical stage atherosclerosis. The present study was carried out to evaluate the efficiency of these methods. Measures including carotid intima-media thickness (CIMT), pulse wave velocity (PWV), and coronary calcium score (CCS) were evalutated for the detection of coronary artery disease (CAD). We studied the clinical and biochemical profiles of individuals with non-CAD and CAD to assess measures of pre-clinical atherosclerosis. The association between CIMT, PWV and CCS on the one hand, and the coronary atherosclerosis on the other, was studied...

Twenty-four-h blood pressure variability (BPV) predicts cardiovascular complications in hypertension, but its association with pulse wave indices (central arterial pressure, pulse wave velocity (PWV) and augmentation index (AIx)) is poorly understood. In the present study, we assessed the degree of the effect of 24-h BPV on 24-h pulse wave indices. Brachial blood pressure was measured non-invasively over the 24 h with an electronic, oscillometric, automated device (BPLab) in 661 uncomplicated treated or untreated hypertensive patients...

The implantation of a stiff aortic endograft for endovascular abdominal aneurysm repair (EVAR) has been reported to increase aortic stiffness and pulse wave velocity (PWV), raising potential concern over deterioration of myocardial performance. Yet, additional stiffness indices such as the augmentation index (AIx), reflection magnitude (RM) and changes in augmentation pressure (AP) have not been studied adequately to facilitate and improve our knowledge regarding the ways that EVAR affects central hemodynamics...

Systemic lupus erythematosus (SLE) is associated with increased cardiovascular risk. We aimed to evaluate arterial stiffness and the ankle brachial index (ABI), two markers of subclinical cardiovascular disease, in SLE. We studied 55 patients with SLE (12.7% males, age 53.3 ± 15.3 years) and 61 age- and gender-matched controls. Arterial stiffness was evaluated by measuring pulse wave velocity (PWV), augmentation index (AIx) and central systolic, diastolic, pulse and mean blood pressure (BP). Peripheral arterial disease was defined as ABI ≤ 0...

The aim of this study was to determine whether pulse wave velocity (PWV), a marker of vascular endothelial impairment and arteriosclerosis, predicts future ischemic stroke in patients who developed acute lacunar infarction. Patients with a first-ever ischemic stroke due to acute lacunar infarction were enrolled in this study. An oscillometric device (Form PWV/ABI; Omron Colin, Tokyo, Japan) was used to measure brachial-ankle PWV 1 week after stroke onset. Patients were followed for at least 5 years. The main end point of the study was recurrent ischemic stroke...

INTRODUCTION: Increased blood pressure (BP) variability is a cardiovascular risk marker for young individuals and may relate to the ability of their aorta to buffer cardiac output. We used a multimodality approach to determine relations between central and peripheral arterial stiffness and BP variability. METHODS: We studied 152 adults (mean age of 31 years) who had BP variability measures based on SD of awake ambulatory BPs, 24-h weighted SD and average real variability (ARV)...
