Abstract Objectives To determine the correlation between anthropometric indices and selected hemodynamic parameters among secondary adolescents aged 12–17 years. Results Our findings showed weak positive generally body surface area, neck circumference conicity index with (systolic blood pressure, diastolic resting pulse rate, mean arterial rate pressure product pressure). However, ponderosity i...

Accurate quantification of arterial function is crucial to distinguishing disease states from normal variants. However, there are little data regarding methods to scale arterial load to body size in humans. We studied 2365 adults aged 35 to 55 years free of overt cardiovascular disease. We assessed arterial hemodynamics and ventricular-vascular coupling with carotid tonometry and Doppler echoca...

Purpose. The work is devoted to study the effects of antihypertensive, lipid-lowering and metabolic therapy in office average hemodynamic parameters, parameters central pressure aorta, vascular wall stiffness quality life patients with CKD stage 3 combination arterial hypertension 1-2 degrees, without it. Materials methods. Were examined degrees 3. Measured help a daily BP monitor “BPLab”. was ...

PURPOSE To investigate and compare the circadian pattern of blood pressure (BP), intraocular pressure (IOP) and mean ocular perfusion pressure (MOPP) while experiencing undisturbed sleep in normal-tension glaucoma (NTG) and non-glaucoma control patient groups. METHODS Twenty-four eyes from 24 patients diagnosed with NTG and 22 eyes from 22 control group patients were enrolled. Systolic BP, di...

The advent of modern Doppler two-dimensional ultrasound technology has overcome the need of invasive measurements of several important cardiac parameters. It allows estimation of preload, contractility, and afterload. Positive end-expiratory pressure (PEEP) is associated with a reduction in cardiac output. The responsible mechanisms are controversial. To evaluate the cardiovascular responses to...

The long-term results of aortic valve replacement were reviewed in all 88 patients with isolated aortic regurgitation and all 103 patients with isolated aortic stenosis who were operated upon at the National Heart and Lung Institute from 1963 to 1971. Survival curves were compared to determine whether any of 30 preoperative clinical and hemodynamic findings correlated with long-term survival. T...

Image-based computational models for quantifying hemodynamic indices in stented coronary arteries often employ biplane angiography and intravascular ultrasound for 3D reconstruction. Recent advances in guidewire simulation algorithms and the rise of optical coherence tomography (OCT) suggest more precise coronary artery reconstruction may be possible. We developed a patientspecific method that ...

This study was performed to determine the relations between the features of wall shear stress and aneurysm rupture. For this purpose, visual data mining was performed in unsteady blood flow simulation data for an aortic aneurysm. The time-series data of wall shear stress given at each grid point were converted to spatial and temporal indices, and the grid points were sorted using a self-organiz...

background: cardiopulmonary bypass is associated with increased fluid accumulation around the heart which influences pulmonary and cardiac diastolic function. the aim of this study was to compare the effects of modified ultrafiltration (muf) versus conventional ultrafiltration (cuf) on duration of mechanical ventilation and hemodynamic status in children undergoing congenital heart surgery.mate...
