Abstract:
Objective To evaluate endothelium dysfunction of arteries for early preventing atherosis. Methods A new portable device for detection of endothelium dysfunction by photoplethysmographic method was designed, which depended on the principle of reactive hyperaemia. Results Experiments between hypertensive and normotensive showed that different degree endothelium dysfunction had emerged among hypertensive. Conclusion The proposed device has potential benefit to research, diagnosis and therapy evaluation for subclinic arterial disease.
