pulse wave velocity

Pulse wave velocity is an auxiliary test used to check the normality of an artery. Arterial stiffness has been identified as an independent risk factor for cardiovascular disease and can independently predict hypertension, coronary heart disease, diabetes, end-vascular vascular nephropathy, cardiovascular disease in the natural population, and all-cause mortality and mortality, and with the left Room hypertrophy, stroke, senile dementia, etc., so the detection of arteriosclerosis has important clinical significance. The clinical significance of non-invasive arteriosclerosis detection in the evaluation of early vascular lesions has received more and more attention, and the cervical pulse wave velocity is the "gold standard" for detecting arteriosclerosis. True and reliable measurements ensure the accuracy and credibility of scientific research results. Through this examination, the corresponding symptoms can be judged. Basic Information Specialist classification: cardiovascular examination classification: electrocardiogram Applicable gender: whether men and women apply fasting: not fasting Tips: Maintain a normal diet and sleep. Normal value The PWV of the normal population was significantly higher than that of patients with stroke and cardiovascular disease during the physical examination. Clinical significance Abnormal result 1pwv refers to the distance that the pulse wave is transmitted along the artery wall for a certain period of time. Pwv can directly reflect arterial compliance. In general, the faster pwv, the worse the arterial elasticity, the higher the stiffness, and vice versa. The population to be examined is ≥60 years old. 2 Patients who have been diagnosed with hypertension (including critical hypertension), hyperlipidemia, diabetes, or risk factors with more than 2 atherosclerosis. 3 patients with confirmed coronary heart disease and stroke. 4 patients with early family history of cardiovascular and cerebrovascular diseases. 5 long-term dizziness, chest discomfort and other symptoms have not been clearly diagnosed; after the activity or resting state, chest tightness, palpitations and other symptoms of precordial discomfort have not been clearly diagnosed. 6 health checkups. Precautions Taboo before check: Maintain normal diet and sleep. Requirements for examination: The patient actively cooperates with the doctor to check, prepares according to the doctor's requirements, and the doctor carefully operates. Inspection process The subject was placed in the supine position, and the baroreceptor was placed in the most obvious part of the right carotid artery, femoral artery, and radial artery. The surface distance between the two points was measured and input into the computer. pwv was based on the two pulse waves. The distance is calculated from the time of the pulse wave conduction. Not suitable for the crowd Inappropriate people: generally no indications.
