Years after a heart stent, some patients can still have a bypass. After having a heart stent, as long as the patient’s heart function is restored to stable and his or her health is relatively good, he or she can still have heart bypass surgery. However, some of the patients who are older, in poor health or with other heart diseases do not have stable heart function and cannot undergo cardiac bypass surgery. Therefore, after many years after cardiac stenting, a portion of patients who are in good health and have stable heart function can still have bypass. If patients want to have heart bypass surgery after many years after cardiac stenting, it is recommended to go to professional departments of regular hospitals for detailed examination, such as electrocardiogram, cardiac ultrasound, coronary angiography and cardiac enzymes examination, etc. Professional doctors will make a comprehensive assessment and analysis based on the examination results, patients’ physical condition, heart function, etc., and finally determine whether they can undergo cardiac bypass surgery or not.
