A coronary angiogram is called a coronary angiogram. Family members are required to accompany the patient during the coronary angiogram, but they usually accompany the patient outside the operating room and are not allowed to enter the operating room. Coronary arteriography requires family members to accompany the patient because if the patient is found to have coronary artery stenosis during coronary arteriography and needs to be treated immediately, he or she needs to communicate with the family immediately and obtain the family’s consent to implant a stent, so the family members should accompany him or her outside the operating room. However, family members are not allowed to enter the operating room because radiation is present in the operating room for coronary angiography, and therefore, unrelated persons other than the patient and the doctor should be avoided from entering the operating room. Coronary angiography can be used for the examination and treatment of coronary heart disease, myocardial infarction, myocardial bridge and other diseases. If coronary angiography is needed, please follow the doctor’s instructions to complete the examination and treatment.
