Renin is the main determinant of angiotensin (Ang) II levels. It, therefore, always appeared desirable to reduce Ang II levels by direct inhibition of renin. So far, specific renin inhibitors lacked potency and/or oral availability. We tested the new orally active nonpeptidic renin inhibitor SPP100 (Aliskiren, an octanamide with a 50% inhibitory(More)
We did a subject-level meta-analysis of the changes (Δ) in blood pressure (BP) observed 3 and 6 months after renal denervation (RDN) at 10 European centers. Recruited patients (n=109; 46.8% women; mean age 58.2 years) had essential hypertension confirmed by ambulatory BP. From baseline to 6 months, treatment score declined slightly from 4.7 to 4.4 drugs per(More)
The treatment of essential hypertension is based essentially on the prescription of four major classes of antihypertensive drugs, i.e. blockers of the renin--angiotensin system, calcium channel blockers, diuretics and beta-blockers. In recent years, very few new drug therapies of hypertension have become available. Therefore, it is crucial for physicians to(More)
T he management of hypertension is based on 2 major approaches: a modification of lifestyle and the lifelong prescription of antihypertensive drugs. 1,2 All hypertension guidelines recognize that " …the most effective therapy prescribed by the most careful clinician will control hypertension only if the patient is motivated to take the prescribed medication(More)
BACKGROUND Contrast-enhanced ultrasonography (CEUS) is a novel imaging technique that is safe and applicable on the bedside. Recent developments seem to enable CEUS to quantify organ perfusion. We performed an exploratory study to determine the ability of CEUS to detect changes in renal perfusion and to correlate them with effective renal plasma flow. (More)
Hypoxia-induced pulmonary vasoconstriction in patients with a medical history of high-altitude pulmonary edema (HAPE) may involve activation of the endothelin-1 (ET-1) pathway. We, therefore, compared the effect of the ETA/ETB receptor antagonist, bosentan, on pulmonary artery systolic pressure (PASP) in healthy subjects with (HS: HAPE subjects, n=5) or(More)
OBJECTIVE We investigated factors associated with masked and white-coat hypertension in a Swiss population-based sample. METHODS The Swiss Kidney Project on Genes in Hypertension is a family-based cross-sectional study. Office and 24-hour ambulatory blood pressure were measured using validated devices. Masked hypertension was defined as office blood(More)
In this review, we discuss the pharmacological and clinical properties of irbesartan, a noncompetitive angiotensin II receptor type 1 antagonist, successfully used for more than a decade in the treatment of essential hypertension. Irbesartan exerts its antihypertensive effect through an inhibitory effect on the pressure response to angiotensin II.(More)
BACKGROUND Higher nighttime blood pressure (BP) and the loss of nocturnal dipping of BP are associated with an increased risk for cardiovascular events. However, the determinants of the loss of nocturnal BP dipping are only beginning to be understood. We investigated whether different indicators of physical activity were associated with the loss of(More)
Poor long-term adherence and persistence to drug therapy is universally recognized as one of the major clinical issues in the management of chronic diseases, and patients with renal diseases are also concerned by this important phenomenon. Chronic kidney disease (CKD) patients belong to the group of subjects with one of the highest burdens of daily pill(More)
