Can coronary angiography for coronary heart disease be performed under general anesthesia?

Coronary angiography can be performed under general anesthesia, but since it is a minimally invasive procedure, local anesthesia is typically used and general anesthesia is usually unnecessary. Moreover, general anesthesia poses slightly greater risks to the body than local anesthesia; therefore, unless absolutely necessary, general anesthesia is not recommended. It is advisable to undergo coronary angiography at a正规 medical institution to effectively ensure the accuracy of the examination.
