In recent years, the incidence of coronary heart disease has been rising rapidly, and the number of people affected is trending younger, and the number of people who die from coronary heart disease in China is at least more than 1 million every year. Coronary heart disease has become an important disease threatening national health. If early detection, early diagnosis and early treatment can avoid tragedy. What kind of people are suitable for coronary CTA examination? Domestic and foreign experts point out that the middle-aged and elderly people with high blood pressure, high blood lipids, high blood sugar “three high” people; people with chest tightness, panic, shortness of breath and other symptoms; no discomfort, but older people should do coronary CTA screening, so that asymptomatic or pre-onset patients can be detected in a timely manner, in order to provide early intervention This can provide a timely and accurate basis for early intervention to reduce the occurrence of sudden acute death events. What is 64-row CT? The 64-row CT introduced to our hospital in June 2006 is one of the world’s most advanced CT equipments, with its extremely fast rotation speed and scanning speed, it only takes 5-10 seconds to examine a heart, and the equipment is also equipped with a large number of coronary artery analysis software such as CPR, MIP, VR, MPR, etc., which can observe the coronary arteries from multiple angles and make the diagnosis of coronary heart disease is no longer difficult. What can be observed by coronary CTA? Coronary CTA can accurately observe: (1) the number, shape and direction of coronary arteries; whether there are congenital developmental abnormalities in coronary arteries; whether there is dilatation, stenosis and its degree and nature of stenosis; (2) whether there is myocardial bridge formation; (3) after coronary stenting and vascular bypass surgery, whether the stent and bridge vessels are broken and whether there is restenosis, etc.; (4) it can also understand the abnormalities of myocardium, valves and heart chambers. What are the advantages of 64-row CT coronary CTA? 64-row CT coronary artery examination can detect lesions early and has the characteristics of high accuracy, small trauma, low cost, simple examination and few complications. 2006 National Cardiovascular Conference identified this kind of examination as the preferred examination method for diagnosing coronary heart disease. It can scan the tissue with a thickness of 0.625mm, observe the coronary arteries from multiple angles, extract the blood vessels individually to straighten and dissect them for analysis, and detect plaques larger than 0.5mm. The sensitivity, specificity and positive prediction rate of coronary artery disease diagnosis reaches 90% and the negative prediction rate reaches 99.1%.
