Arterial Disease Clinical Trial
— POEMEOfficial title:
Dynamic Arterial Elastance: an Indirect Marker of the Critical Capillary Pressure at the Microcirculatory Level (POEME)
The measurement of dynamic arterial elastance (Eadyn) was proposed as a marker of vascular tone. It is calculated by the ratio of the respiratory variation of the pulse pressure and the respiratory variation of stroke volume. Despite several clinical studies, no study has really focused on the physiological significance of Eadyn. No study demonstrates at present, if this index is a reflect of macrocirculatory parameters (systemic resistances, blood pressure, arterial elastance, ventricular elastance, ventriculo-arterial coupling) or microcirculatory tone in the capillaries and small arterioles (critical capillary pressure or capillary resistance). the physicians don't know which variables are associated with this index. the hypothesis is that Eadyn is an indirect reflect of capillary pressure (PCC).
