Cardiac angiography and stenting can be performed together, as both are minimally invasive procedures and can share the same route. There are various factors that determine whether they can be performed together, including the patient’s physical condition, cardiac function status, and medication intake. If the patient’s heart function is poor and the antiplatelet medication is not long enough, it is recommended that the patient undergo stent implantation at an elective stage; if the patient has a critical lesion, such as high-risk unstable angina, or acute myocardial infarction, the vessel needs to be opened as soon as possible, and coronary angiography and stenting can be performed at the same time if conditions allow; if the patient’s condition is more complicated, such as multi-branch lesions, bifurcation lesions or completely occluded lesions in the coronary arteries, it is recommended that Coronary angiography should be performed first, and the next step of treatment should be performed after the consultation is completed.
