Renal haemodynamics and coronary atherosclerotic burden are associated in patients with hypertension and mild coronary artery disease
2019
Intrarenal hemodynamic alterations are independent predictors of cardiovascular events in different populations. It has been hypothesized that there is an association between renal hemodynamics and coronary atherosclerotic burden in patients with hypertension. Therefore, the present study examined the associations between renal hemodynamics, coronary atherosclerotic burden and carotid atherosclerotic disease. A total of 130 patients with hypertension aged between 30-80 years who had been referred for an elective coronary angiography were enrolled in the present study. A duplex ultrasound of the intrarenal vasculature was performed to evaluate the resistive index (RI), pulsatility index (PI)…
Long-term evaluation of quinapril in mild to moderate hypertension: assessment of renal haemodynamics and function.

Effects of amlodipine on renal haemodynamics in mild to moderate hypertensive patients. A randomized controlled study versus placebo. Eur J Clin Phar…

In this study the efficacy and safety of short-term amlodipine administration on renal haemodynamics were evaluated in mild to moderate hypertensive subjects. Our final goal was to evaluate whether the reduced blood pressure induced by treatment was associated with maintenance of renal function. After a run-in period with placebo, 30 hypertensive patients without cardiac or renal diseases were randomly allocated to a double-blind 4 weeks controlled study with amlodipine 10 mg once a day (15 patients) or placebo (15 patients). Renal haemodynamic measurements included effective renal plasma flow (ERPF) and glomerular filtration rate (GFR) by radionuclide study using 131I-hippuran and 99mTc, w…
INVERSE RELATIONSHIPS BETWEEN CHOROIDAL THICKNESS AND RENAL RESISTANCE INDEX IN HYPERTENSIVE PATIENTS
2019
Introduction: Alterations of the renal microcirculation have been documented in animal models of hypertensive renal damage. Traditionally, the retina has been considered the easiest accessible window to study the systemic microcirculation, even though the choroid is the most important vascular layer of the eye. The introduction in the past few years of advanced optical coherence tomography (OCT) techniques has greatly increased our understanding of the choroid. Although the renal resistive index (RRI) was initially considered to reflect intrarenal vascular pathological processes, this index is actually regarded as the result of complex interaction between renal and systemic vascular wall pr…
