Heart CT can detect coronary heart disease

Cardiac CT is not the gold standard for diagnosing coronary heart disease. It has limitations and needs to be used in combination with other tests. Coronary angiography is the gold standard. Cardiac CT can help doctors diagnose coronary heart disease, but it is not the gold standard for diagnosing coronary heart disease. Cardiac CT scans the heart by injecting contrast media into the coronary arteries and using X-rays to scan the heart, thereby revealing the shape and stenosis of the coronary arteries. It can detect calcified plaques, stenosis or obstruction of the coronary arteries, but it is difficult to accurately determine soft plaques in the coronary arteries and inflammatory reactions in the blood vessel walls. Here are some points to note: 1. Limitations: The diagnostic accuracy of cardiac CT examination for coronary artery stenosis is affected by many factors, such as heart rate, heart rhythm, quality of contrast medium injection, etc. In addition, the accuracy of cardiac CT examination may be reduced for some special conditions, such as multi-vessel disease, small vessel disease or bypass vessel disease. 2. Supplements of other examinations: Cardiac CT examination is usually used in combination with other examination methods, such as electrocardiogram, exercise stress test, coronary angiography, etc., to improve the accuracy of diagnosis. 3. Gold standard for diagnosis: Coronary angiography is considered to be the gold standard for the diagnosis of coronary heart disease. It can Directly observe the internal conditions of the coronary arteries and perform interventional therapy or vascular reconstruction. For patients suspected of coronary heart disease, doctors will select appropriate examination methods according to specific conditions, and make comprehensive judgment based on clinical symptoms and medical history. If the results of cardiac CT examination suggest coronary artery stenosis, further coronary angiography or other examinations are needed to confirm the diagnosis and formulate corresponding treatment plan. In addition, for some high-risk groups, such as family history of coronary heart disease, hypertension, diabetes, hyperlipidemia and other diseases, regular cardiac examination is very important, can early detection and intervention of coronary heart disease occurrence and development. In short, cardiac CT examination in the diagnosis of coronary heart disease has a certain role, but not the only diagnostic method. In the diagnosis of coronary heart disease, it is necessary to consider a variety of factors, and according to the specific conditions of patients for individualized diagnosis and treatment.
