Endothelial Dysfunction in Reversible Cerebral Vasoconstriction Syndrome
Ključne riječi
Sažetak
Opis
The investigators lead a case control study to find a systemic endothelial dysfunction by the using of Complior device. Complior is a mechanographer who calculates pulse wave velocity (PWV). Pulse wave velocity is a reflect of arterial stiffness and it's correlate with endothelial dysfunction. For BHI, a Philips echograph is used before and after 30 second of breath holding.
Study protocol is :
For Patient :
- Day 0 : in hospital : anamnesis, medical history, physic examination, EKG, blood sample analysis, BHI, PWV analysis
- Month 1 : in medical visit : medical evolution, physic examination, EKG, blood sample analysis, BHI, PWV analysis
- Month 3 : in medical visit : medical evolution, physic examination, EKG, blood sample analysis, BHI, PWV analysis, cerebral angioCT Scan
For control :
- Day 0 : in hospital : medical history, physic examination, EKG, BHI, PWV analysis
