Atherosclerosis is a systemic disease, which is a judgment indicator of subclinical organ damage and is the most important cause of cardiovascular and cerebrovascular diseases. In order to make atherosclerosis, a systemic disease, detectable at an early stage and prevented and controlled at an early stage. With the support of the hospital, the Health Screening Department has introduced a new networked atherosclerosis detection device, the Blood Pressure Pulse Examination Device (BP-203RPEШ), to serve the health screening and the screening of people at high risk of stroke. Zhao Jing, Health Screening Center, Xuanwu Hospital, Capital Medical University The device evaluates and diagnoses atherosclerosis by measuring the following four main assessment parameters through the unique double cuff simultaneous detection and filtering technology of blood pressure in the extremities: 1. ankle/upper arm blood pressure ratio (ABI) to evaluate the degree of arterial blockage or stenosis in the lower extremities; 2. ankle-brachial pulse wave velocity (baPWV) to quantitatively analyze the stiffness and elasticity of blood vessels throughout the body; 3. 3.Carotid-femoral wave conduction velocity (cfPWV) is used to detect the elasticity of large arteries; 4.Toe and arm index (TBI) is used to evaluate diabetic foot. This test is convenient and easy to perform, non-invasive and painless without exposing privacy. The test report contains a vascular image schematic, trend diagram and metabolic syndrome risk assessment, which is helpful for the examinees to deepen their understanding and help guide doctors to develop a comprehensive treatment plan. The test is already in use in the Health Screening Department for those who have been diagnosed with hypertension, hyperlipidemia, diabetes, metabolic syndrome, coronary heart disease and stroke; for those with a family history of early onset cardiovascular disease, obesity, long-term smoking, high-fat diet, lack of physical activity, mental tension or stress, and other high-risk factors for cardiovascular disease; and for those with chronic dizziness or palpitations. It is also used for people who have chronic dizziness, palpitation, chest discomfort and other discomfort in the precordial region but have not yet been diagnosed, and for screening and evaluation of the degree of atherosclerosis in the above health check-up population.
