Reducing pulse pressure in hypertension may normalize small artery structure.
To investigate the relation between the small artery structure and different blood pressure parameters, spontaneously hypertensive rats were treated from 4 to 24 weeks of age (20 weeks in total) with five different antihypertensive therapies: two angiotensin converting enzyme inhibitors (perindopril and captopril), a calcium antagonist (isradipine), a beta-blocker (metoprolol), and a vasodilato...
متن کاملPulse pressure and presence of coronary artery calcification.
BACKGROUND Coronary calcification (CAC) is found in early stages of CKD. Pulse pressure (PP) predicts CAC in dialysis patients. This study evaluates the accuracy of PP in predicting CAC in patients not yet on dialysis (CKD patients). METHODS CKD patients (n = 388) underwent coronary calcium score (CAC score) and abdominal x-ray (n = 128) for estimating aorta calcification (AAC). Biochemistry ...
متن کاملPulse-pressure variation and hemodynamic response in patients with elevated pulmonary artery pressure: a clinical study
INTRODUCTION Pulse-pressure variation (PPV) due to increased right ventricular afterload and dysfunction may misleadingly suggest volume responsiveness. We aimed to assess prediction of volume responsiveness with PPV in patients with increased pulmonary artery pressure. METHODS Fifteen cardiac surgery patients with a history of increased pulmonary artery pressure (mean pressure, 27 +/- 5 mm H...
متن کاملInvestigation of Pressure Pulse Distribution in Porous Media
Diffusivity equation commonly used for pressure distribution prediction in porous media results from substituting equation of state and continuity equation in Navier-Stokes momentum equation. From mathematical point of view this equation format shows infinite propagation speed for pressure pulse through porous media, which is physically impossible. This issue may caused by numerous assumption...
متن کاملEndothelial function is associated with pulse pressure, pulse wave velocity, and augmentation index in healthy humans.
Arterial stiffness is an independent predictor of mortality and is regulated by a number of factors, including vascular smooth muscle tone. However, the relationship between endothelial function and definitive measures of arterial stiffness and wave reflections has not been described in healthy individuals. Therefore, we tested the hypothesis that endothelial function is inversely correlated wi...
