In general, elective cardiac stenting has little impact on patient life expectancy, ranging from years to decades of survival, with remedial stenting resulting in decreased survival and prognosis. Cardiac stenting, or percutaneous coronary intervention, is a minimally invasive procedure commonly used in clinical practice to treat myocardial ischemia due to coronary artery stenosis. Elective surgery after comprehensive evaluation can effectively relieve the symptoms of myocardial ischemia, and patients’ exercise tolerance and quality of life are significantly improved. However, when the intervention is a remedial procedure, the likelihood of postoperative complications such as reinfarction and in-stent thrombosis is greatly elevated, and the patient’s survival may be more significantly reduced. It is worth noting that both elective and remedial surgery require strict control of blood glucose, lipids and other biochemical indicators, the elevation of these indicators will increase the risk of postoperative complications. Only a reasonable diet and regular routine can maximize the therapeutic effect of stenting and prolong the patient’s survival. If there is any discomfort, it is recommended to go to the hospital immediately and follow the medical advice.
