Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Augmented Velocity Index (Avi) is a new Doppler index which can potentially be used to assess arterial stiffness. The Avi of common carotid artery is found to be associated with arterial stiffness and have initial correlation with cardiovascular risk factors. Avi can be used in any vessels (superficial or deep vessels) where arterial Doppler waveforms can be obtained.
Aims:
The aims of this study are to investigate the associations of Avi of hepatic artery, renal artery, central retinal artery and internal carotid artery with arterial stiffness and cardiovascular risk factors in a group of apparently normal subjects.
Methods:
Recruit 350 subjects with no known medical illness or drug treatment for ultrasound examinations and blood tests. In ultrasound examination, the Avi of carotid arteries, hepatic arteries, renal arteries and retinal arteries are recorded. The carotid-femoral pulse wave velocity is also calculated for the assessment of central aortic stiffness.
Other important correlates of arterial stiffness including carotid intima-media thickness, fatty liver status, liver stiffness and abdominal fat thickness are assessed in the ultrasound examination.
The clinical and laboratory examinations include anthropometric indexes, plasma glucose level, lipid profile, renal function tests, liver function test, urinary albumin creatinine ratio, blood pressure measurement.
