Can CT detect coronary heart disease?

CT examination is helpful to coronary heart disease, but it is not the gold standard. It needs to be combined with other examinations to make comprehensive judgment. If necessary, consult experts. CT examination can help detect coronary heart disease to a certain extent, but it is not the gold standard for diagnosing coronary heart disease. Coronary heart disease is a disease caused by myocardial ischemia and hypoxia due to coronary atherosclerosis. CT coronary angiography (CTA) is a commonly used imaging method that provides information about coronary artery disease by scanning coronary arteries to observe the shape and stenosis of the vessels. CTA can detect calcified plaques in coronary arteries, which is an important marker of coronary artery disease. However, CTA has some limitations. The accuracy of CTA in detecting coronary artery stenosis may be affected by plaque nature, quality of angiography, etc. In addition, CTA may not be accurate in diagnosing mild or complex coronary artery disease. To diagnose coronary artery disease more accurately, doctors may combine other tests, such as coronary angiography, ECG, myocardial enzymes, etc. Coronary angiography is an invasive examination method. By injecting contrast medium into coronary arteries, the blood vessels are directly observed, but it needs to be performed in the catheterization laboratory, which has certain risks. In addition to the examination method, doctors will also consider the patient's symptoms and risk factors to determine whether coronary heart disease exists. If coronary heart disease is suspected, your doctor may recommend further tests or consult a cardiovascular specialist. CTA may not be the best option for certain populations, such as pregnant women or people with contrast media allergies. In such cases, your doctor may choose other appropriate tests depending on the circumstances. In general, CT examination can be used as an initial screening tool for coronary heart disease, but it cannot be relied on alone to confirm coronary heart disease. If there is doubt about coronary heart disease, seek medical attention in time for a comprehensive evaluation and diagnosis.
