|Official Title:||Evaluation of the Action of the Stendo Pulsating Suit on Peripheral Microcirculation and on Central Blood Pressure in Essential Hypertension Patients Treated But Not Stabilized|
- Peripheral microcirculation measured using Laser Doppler flowmetry [ Time Frame: 35 minutes after the end of the Stendo session at D1 + 7 jours +/- 3 ]Change in % of the peripheral cutaneous microcirculation using laser Doppler flowmetry after one Stendo pulsating suit session
- Humeral arterial pressure [ Time Frame: 20 minutes after the end of Stendo session at D1 + 7 jours +/- 3 ]Humeral arterial pressure using automatic measures with Dinamap device
- Central blood pressure [ Time Frame: Just after the end of the Stendo session.at D1 + 7 jours +/- 3 ]Central blood pressure measured by applanation using an applanation tonometry device; Central pulse pressure, Augmentation Index and subendocardial viability ratio will also be assessed.

Experimental: Stendo pulsating suit System
One 20 minutes Stendo pulsating suit session will be applied to the patient.
Device: Stendo pulsating suit System
The Stendo system, a multilayer pulsatile inflatable suit is applied to the lower limbs and the abdomen. This device induces a sequential compartmentalized compression synchronized with each diastolic phase of the cardiac cycle, each phase evolving centripetally (lower limbs to abdomen).
The role of the endothelium in micro-vascular system is mediated by synthesis and release of numerous substances that act on the smooth muscle fibres. The release of these products is modulated, in turn, by various circulating molecules, by the autonomic nervous system and by local mechanical factors such as shear stress.
The essential hypertension is associated to increased risks of cardiovascular and stroke morbidity and mortality and constitutes a major cause of severe kidney failure. The essential hypertension is a complex and multi-factorial disease; the dysfunction of the endothelium is of a great importance in the physiopathology of this disease, concerning both the consequences of the increase of the blood pressure and the possible cause of the hypertension development.
The Stendo pulsating suit is expected to increase the cutaneous microcirculation measured by laser Doppler laser flowmetry and potentially to decrease the central blood pressure. Each patient will be his own witness and the clinical records will be assessed before, during when relevant, and after a pulsating suit session.
