Patient's question:
I doubt that I have coronary heart disease, but I'm not sure. I want to know how to check for coronary heart disease. I want to go to the hospital for treatment, but I don't know how to check it more accurately. So, I want to ask how to accurately check for coronary heart disease?Doctor's answer:
Coronary heart disease is a disease caused by the recurrence of stenosis in the coronary arteries, but it doesn't necessarily mean that symptoms will appear just because the coronary arteries narrow again. Generally, changes indicating blood supply insufficiency on an electrocardiogram (ECG) may occur when the coronary artery stenosis reaches about 70%. Coronary CT can detect coronary stenosis. Coronary angiography is the gold standard for diagnosis, with high sensitivity and specificity. It is recommended that patients receive timely treatment.
