According to the statistics of the World Health Organization, cardiovascular disease is the number one cause of death in the world, among which coronary heart disease (CHD) is the most common cause. Many people prefer fatty diet, high stress and lack of exercise. If combined with the bad habit of smoking, it is easy to get into the "three highs", which can then lead to atherosclerosis and damage to the inner wall of blood vessels, leading to coronary heart disease; If the condition worsens, it can induce angina pectoris and myocardial infarction, even life-threatening!<\/p>\n\n\n\n
There are several methods for diagnosing coronary heart disease. The first is of course clinical examination. If there are suspected symptoms or "three high" patients, family members who have suffered from heart disease and other high-risk groups, relevant examinations can be considered. Doctors generally use an electrocardiogram (ECG) as a preliminary examination to observe the patient's heartbeat and evaluate myocardial tissue and coronary artery function. This examination is simple and convenient, but the results are prone to errors, such as abnormal results or high risk of disease. Non-invasive coronary computerized angiography (CCTA) is also one of the commonly used diagnostic methods.<\/p>\n\n\n\n
This radiography technology uses X-rays, rotary scanning equipment, combined with calculation and analysis of advanced computer systems, to form two-dimensional or three-dimensional images of the cross-section of the heart and cardiovascular system to assist doctors in quickly diagnosing cardiovascular stenosis and obstruction. With the advancement of technology, the accuracy and detection efficiency of the new generation of instruments have been greatly improved, and the amount of radiation released is also relatively small. It is worth mentioning that coronary artery calcification is an important marker of plaque buildup or atherosclerosis on blood vessels. If there is calcification in the coronary artery of the patient, the quantitative examination of coronary artery calcification by CCTA can provide an important reference for evaluating the degree of calcification.<\/p>\n\n\n\n
However, CCTA has limitations, such as those who are allergic to the contrast agent, renal failure, pregnant women, etc. may not be suitable for the examination; after the examination, if it is necessary to further confirm the condition and determine whether surgery is necessary, the doctor may arrange other tests such as Cardiac catheterization, fractional flow reserve angiography, etc.<\/p>\n\n\n\n
