Both coronary angiography and coronary ct can be used to diagnose coronary artery disease, the main difference lies in whether it is invasive or not, the contraindication criteria and the role of observation.
1. Whether invasive: coronary angiography is invasive, need to open the arterial access, the cost is higher. Coronary ct is non-invasive and less expensive.
2. Contraindication criteria: some patients with coagulation factor disorders, coronary artery stenosis, etc. is not convenient for coronary angiography, and coronary ct has many influencing factors, such as emotional impact, unstable heart rate, etc., such as symptoms are serious, it is not recommended to perform coronary ct immediately.
3. Observation: both have a diagnostic role, but coronary angiography directly into the arteries, the results are more accurate and detailed, for the gold standard of diagnosis, while the coronary ct has too many influencing factors, and is mostly used for initial screening.
Because of the complexity of the choice between coronary angiography and coronary ct, it is recommended to go to a regular hospital to inquire and choose in conjunction with your own situation.
