Cardiac interventional stenting can provide excellent relief of stenosis, and with scientific post-procedure care, life expectancy is generally not affected without complications. Stent surgery is generally known as “percutaneous coronary intervention”, mostly elective surgery, is commonly used in the treatment of coronary atherosclerosis caused by myocardial ischemia symptoms of minimally invasive surgery, technology is mature, the risk is small, and the prognosis is generally good. Patients need long-term dual-antibiotic therapy to avoid complications such as in-stent thrombosis, and the most commonly used dual-antibiotic drug is aspirin combined with clopidogrel. In the absence of complications, patients’ life expectancy is generally unaffected. However, for patients undergoing remedial stenting after the development of an acute coronary syndrome, the prognosis is significantly lower than the survival rate of patients undergoing elective surgery; therefore, early surgery under the guidance of a medical professional is recommended for patients who have reached the indication for surgery.
