If a patient has not taken medication regularly for 8 years after cardiac stenting, or if he/she develops uncomfortable symptoms, it is recommended to undergo coronary artery angiography; if there is no obvious discomfort, angiography is not necessary.
If the patient does not take regular medication such as aspirin and other antiplatelet aggregating drugs, atorvastatin and other lipid-lowering drugs during the 8-year period after coronary stenting, and there are uncomfortable symptoms such as chest pain, chest tightness, radiating pain, etc., and there is a suspicion of new-onset coronary atherosclerosis or restenosis within the stent, it is recommended to repeat coronary angiography to clarify the situation of coronary arteries and the stent.
If the patient takes medication regularly after the operation and has no obvious discomfort symptoms, it is sufficient to review the routine blood test, liver function, kidney function, blood lipid, cardiac enzymes, chest CT, cardiac ultrasound, etc. after 8 years, and generally there is no need for coronary angiography.
Whether or not coronary angiography is needed for review after 8 years of coronary stent implantation is recommended to consult a professional doctor, who will give advice according to the patient’s condition.
