Patient's question:
What is the detailed process of coronary angiography? Under what circumstances is it performed?Doctor's answer:
Coronary angiography is a minimally invasive procedure where a soft, thin catheter is inserted through a puncture in the wrist or leg vessels into the opening of the coronary arteries, and a contrast agent is injected to visualize the inflammation of the coronary arteries, as well as to check for stenosis, expansion, blockages, and other abnormalities. It is one of the diagnostic methods for coronary heart disease, with coronary angiography and CT angiography being the most reliable. If angina has been confirmed or strongly suspected, it is best to perform coronary angiography directly. If the symptoms are atypical and only need to rule out angina, coronary CT angiography can be done first. Cardiovascular angiography is highly helpful for the examination and treatment of coronary heart disease, and it is a surgical examination. It is recommended that patients stay in the hospital to minimize risks.
