For most cardiovascular diseases, atherosclerotic lesions are the common pathophysiological basis. As an important part of the circulatory system, atherosclerotic lesions can occur in any part of the arteries of the body. Therefore, active prevention and treatment of atherosclerotic diseases is regarded as the core of the prevention and treatment of cardiovascular diseases, and strengthening screening and early diagnosis of atherosclerotic lesions becomes the key link to improve the prevention and treatment of cardiovascular and cerebrovascular diseases. Ultrasound examination of abdomen and peripheral vessels is a safe, non-invasive, simple and inexpensive vascular examination method, which is free of X-ray radiation to human body and can be repeated within a short period of time, and can directly observe the arteriovenous vessel wall and lumen, and measure hemodynamic parameters such as blood flow velocity and resistance index. Echo tracking (ET) technology is a new ultrasound technology applied in clinical practice in recent years, which can dynamically track and trace the trajectory of the vessel wall and automatically calculate and display the magnitude of changes in the internal diameter of the vessel. The whole-body atherosclerosis measurement can detect arterial stiffness and the degree of arterial obstruction. It uses “waveform analysis and vascular assessment” technology to provide non-invasive, rapid, sensitive and accurate clinical data such as PWV (pulse velocity) and ABI (ankle brachial index) for the early detection and treatment of major diseases such as cardiovascular, cerebrovascular and diabetes, and is a comprehensive screening and prognostic assessment device. Selective use of the above three methods for early, non-invasive vascular testing enables early detection of vascular diseases, early intervention and timely treatment if necessary, ultimately leading to prevention of cardiovascular diseases and improvement of physical quality.
