Against the backdrop of a high incidence of cardiovascular diseases (CVD) worldwide, arteriosclerosis, as its core pathological basis, has become an “invisible killer” threatening human health. According to the “China Cardiovascular Health and Disease Report 2023″, the current number of people suffering from cardiovascular diseases in China has reached 330 million, among which atherosclerotic lesions account for over 80%.
Early identification of the risk of arteriosclerosis and precise intervention have become key breakthroughs in reducing the incidence of cardiovascular and cerebrovascular events. As a non-invasive and precise modern detection tool, the arteriosclerosis detector, with its scientific nature and clinical value, has opened a “window” for us to understand vascular health.
Principle: Dual indicators work together to build the “Gold Standard” for diagnosis
The arteriosclerosis detector focuses on two major indicators: pulse wave velocity (PWV) and ankle-brachial index (ABI), forming a “velocity – pressure” dual-dimensional assessment model, achieving a three-dimensional assessment from “local lesions” to “systemic arteriosclerosis”.
PWV: The “Speedometer” of Vascular Elasticity
As an indicator for detecting arteriosclerosis explicitly recommended by the 2003 European Hypertension Guidelines, PWV quantitatively assesses the stiffness of the vascular wall by measuring the velocity of pulse waves in the arteries. The principle is based on the physical relationship between elastic modulus and wave velocity (v=√(Eh/ρ)), and the higher the value, the worse the elasticity of the blood vessel. Clinical studies have confirmed that for every 1m/s increase in PWV, the risk of cardiovascular events rises by 15% (Lancet, 2006), and it is an independent risk factor for predicting myocardial infarction and stroke.
ABI: The “Pressure Gauge” of Peripheral Circulation
In accordance with the 1993 standards of the American Heart Association (AHA), ABI accurately screens for lower extremity arterial disease by calculating the ratio of ankle to upper arm systolic blood pressure. ABI≤0.9 indicates the presence of peripheral artery occlusion, while ABI>1.3 May reflect arterial calcification. More importantly, lower extremity arterial disease and coronary artery disease have a high degree of homology. People with abnormal ABI have a 3-4 times increased risk of developing coronary heart disease in the future (NEJM, 2001).
Technical advantages: Non-invasive, precise, and simple
Compared with traditional vascular examination methods, the Pinyuan Medical Arteriosclerosis detector has significant advantages:
Non-invasive and painless: The entire process only requires wearing a cuff like measuring blood pressure, is non-invasive and non-radioactive, has a high acceptance rate among patients, and can be easily repeated.
Fast and simple: A complete test only takes 3 to 5 minutes. The operation is automated and reports are issued in real time, which improves the inspection efficiency.
Highly objective and precise: Quantitative indicators (PWV value, ABI value) eliminate the subjective judgment errors of the operator, ensuring accurate and reliable results, which is convenient for comparison before and after and long-term follow-up.
Early warning: It can detect functional changes in vascular elasticity before structural vascular stenosis occurs, achieving true “early detection and early prevention”.
Standard testing procedure
Preparation: The examinee should expose their wrists and ankles.
Position: Lie on your back on the examination table, relax your whole body, place your arms at your sides, and keep your feet slightly apart.
Connection: Attach the blood pressure cuff for the limbs to the left and right upper arms and ankles.
Measurement: The operator starts the device, and the cuff will automatically inflate and deflate (the sensation when the air pressure is lower than that when measuring blood pressure), simultaneously collecting various signals.
Completion: The equipment automatically processes data and generates reports.
Keep quiet throughout the process and do not move your body.
Clinical value and significance
The arteriosclerosis detector is not only an examination device in the outpatient department, but also a powerful tool for clinical doctors
Health screening: As a routine physical examination item, it provides vascular health assessment for sub-healthy people and high-risk groups (such as those with hypertension, diabetes, hyperlipidemia, and smokers).
Auxiliary diagnosis: It provides objective diagnostic basis for departments such as cardiology, endocrinology, nephrology, and geriatrics, and assists in the diagnosis of arteriosclerosis, peripheral artery disease, etc.
Therapeutic effect evaluation: Precisely and quantitatively assess the improvement effects of drug treatment (such as antihypertensive drugs, lipid-lowering drugs) and lifestyle intervention (such as exercise, diet) on vascular health.
Risk prediction: A large number of clinical studies have confirmed that PWV is a strong predictor of cardiovascular and cerebrovascular events (myocardial infarction, stroke) independent of traditional risk factors, and an increase in its value indicates a significant increase in future risk.
From “passive treatment” to “active health”, the arteriosclerosis detector is not only a diagnostic tool but also a “strategic weapon” for cardiovascular disease detection. By early detection of vascular aging signals, quantitative assessment of intervention effects, and construction of a new paradigm in preventive medicine.
