Influence of a calcium antagonist on blood rheology and arterial compliance in hypertension: comparison with a thiazide diuretic.

Beyond their effects on blood pressure, antihypertensive agents may produce additional effects on blood rheology and arterial compliance abnormalities which may play a role in the target organ damage. These effects may depend only on their specific pharmacological properties. We compared the effects of nitrendipine to hydrochlorothiazide in 33 mild to moderate hypertensives in a double blind parallel group trial.

Calcium antagonists and thiazide diuretics have opposite effects on blood rheology and radial artery compliance in arterial hypertension: a randomized double-blind study.

In addition to their effects on blood pressure, antihypertensive agents may produce additional effects on blood rheology and arterial compliance abnormalities which may play a role in target-organ damage. However, these effects may depend only on the specific pharmacological properties of certain antihypertensive agents, and may be partly unrelated to blood pressure lowering action. We compared the effects of nitrendipine 20 mg once daily to hydrochlorothiazide 25 mg once daily in 33 mildly to moderately hypertensive and otherwise healthy patients, in a double blind parallel group trial.

[Double-blind randomized comparative study of nicergoline naftidrofuryl on the quality of life in chronic obliterative arteriopathy of lower limbs with intermittent claudication].

The functional limitation of patients with obliterative arterial disease, and with intermittent claudication, damages their quality of life. The purpose of this trial was to compare the effects of nicergoline and naftidrofuryl on the quality of life and the functional discomfort of the 131 patients with claudication. It was a multicentre, randomised, double-blind trial with parallel groups.

Effects of beta-adrenergic blockade on short-term variability of blood pressure and heart rate in essential hypertension.

Short-term fluctuations in blood pressure (BP) and heart rate (HR) were analysed in a group of twelve males with essential hypertension. Indirect finger BP was measured by a Finapres device. The effect of a 7-day administration of a cardioselective beta-adrenoceptor blocker, acebutolol (400 mg/day), was studied in a double-blind, randomized, placebo-controlled cross-over study.

[Regional arterial hemodynamics and carotid circulation in essential arterial hypertension. Effect of nitrendipine in patients over 40 years of age].

Lesions of the arterial wall constitute one of the main complications of essential hypertension. The final objective of all antihypertensive drugs is to reduce the cardiovascular morbidity and mortality rates, but their short and medium term objectives must be to normalise blood pressure values and to correct the functional and structural abnormalities consecutive to arterial hypertension. In this double-blind drug versus placebo study conducted in 20 patients (14 men, 6 women) aged over 40, the effects of nitrendipine on regional arterial haemodynamics (aortic territory, upper limb, lower limb) and carotid circulation were evaluated.
