For many people who suspect coronary artery disease, I’m afraid the most common word I’ve heard in recent years is coronary artery stenting. Coronary angiography, also known as coronary angiography, has long been regarded as the “gold standard” for the diagnosis of coronary heart disease, and is also a precursor to the placement of stents for severe coronary stenosis. Therefore, coronary angiography and stenting seem to have become a one-way street for coronary heart disease and a myth of diagnosis and treatment. It is a non-invasive test that can be used to screen for coronary artery disease and initially determine the degree of coronary artery stenosis. Compared with coronary angiography, CTA has some obvious advantages, such as it can simultaneously do coronary calcification score to evaluate the risk of coronary heart disease; it can obviously show the nature of plaque, and the clinical significance of hard or vulnerable plaque is different; in addition, CTA can also evaluate the luminal status of implanted stents; it can also simultaneously show cardiac changes, such as atrial enlargement, old infarction, ventricular wall aneurysm, etc.; on the other hand, for coronary artery alignment The most important point is that coronary angiography is an invasive examination with certain surgical risks. With this analysis, we can see that CTA is preferred for diagnostic purposes for milder symptoms, which can make a preliminary diagnosis of coronary artery disease and determine the degree of coronary stenosis. However, for patients with acute attacks and a clear clinical diagnosis of myocardial infarction, emergency coronary angioplasty and stent implantation are important tools to save lives. For this issue, there are many international and domestic guidelines for diagnosis and treatment. Specifically for each patient, it is better to listen more to the doctor’s opinion rather than blindly going for any kind of examination.
