We often talk about “heart attack” and “stroke”, but we do not know that it is not a day’s cold to freeze three feet, and atherosclerosis and atherosclerosis are typical features of arterial vascular structure and function lesions are common to myocardial infarction, stroke and other cardiovascular diseases. The pathological basis for myocardial infarction, stroke and other cardiovascular diseases. Early detection of structural and functional lesions of the arterial vasculature and timely and effective intervention are fundamental measures to prevent these end-stage cardiovascular diseases. Atherosclerosis is detectable and is a rapid, painless test with high sensitivity, reliability and reproducibility, and can be used for early diagnosis of systemic atherosclerosis; assessment and prediction of cardiovascular and cerebrovascular disease risk; and assessment of the effectiveness of anti-hypertensive and anti-atherosclerotic drug therapy. This test has been included in the guidelines and expert consensus of many countries, including China, for the prevention and treatment of cardiovascular and diabetes. If you meet the following conditions, it is recommended that you undergo atherosclerosis testing: 1, have been diagnosed with hypertension (including critical hypertension), hyperlipidemia, diabetes (including elevated fasting glucose and reduced glucose tolerance); or have obesity, long-term smoking, high-fat diet, lack of exercise, mental stress or high stress and other cardiovascular and cerebrovascular disease risk factors. 2.Family history of cardiovascular disease. 3, Long-term dizziness and other discomfort symptoms, not yet clearly diagnosed. 4.Symptoms of chest tightness, palpitations and other discomfort in the precordial region after activity or at rest, which have not been clearly diagnosed. 5.Diagnosed coronary heart disease, unstable angina or heart machine infarction (acute or old).
