Reactive hyperaemia releases t-PA in essential hypertensive patients

Dopaminergic abnormalities in borderline essential hypertensive patients.

To explore whether an altered metabolic pathway of dihydroxyphenylalanine (DOPA) may be related to some previously observed dopamine abnormalities in borderline hypertension, we measured basal and DOPA-induced (500 mg orally) changes in blood pressure and pulse rate as well as in three hourly plasma and urine samples. We found that borderline hypertensive patients compared with controls 1) show...

Perineural capsaicin treatment attenuates reactive hyperaemia in the rat skin.

The neural mechanisms of reactive cutaneous hyperaemia were studied by using a novel experimental approach: the simultaneous measurement of cutaneous blood flow by laser-Doppler flowmetry in adjacent innervated and chemodenervated skin regions of the rat hindpaw served by the same artery. Transient occlusion of the femoral artery (0.5-6 min) resulted in reactive hyperaemia that was greatly redu...

Changes of Reactive Hyperemia Index (RHI) in Hypertensive Patients

Recent epidemiological evidences indicates a complex association of hypertension with vascular endothelial dysfunction which causes the development and progression of atherosclerosis leading to adverse cardiovascular and cerebrovascular events due to reduction in nitric oxide (NO) bioavailability. The aim of the study was to investigate the value on reactive hyperemia peripheral arterial tonome...

Role of insulin resistance in nondipper essential hypertensive patients.

In hypertensive patients, diminished nocturnal blood pressure (BP) fall is associated with poor prognosis for cardiovascular events. However, the relation of insulin resistance with the etiology of nondipper essential hypertension remains unclear. The aim of the present study was to assess the role of insulin resistance in diminished nocturnal BP fall, left ventricular hypertrophy (LVH), and in...
