After cardiac stenting, triglycerides are lowered and LDL is elevated, and intensive lipid-lowering therapy with drugs should be taken along with lifestyle improvement. For patients with coronary artery disease, especially after stenting, the level of LDL should be strictly controlled, and the general requirement is that the LDL should be lower than 1.8 mmol/L. In this case, on the one hand, it is necessary to continue to improve the poor lifestyle, to avoid dietary grease and high salt, to quit smoking and drinking, and at the same time, to carry out aerobic exercise when the body is allowed to do so. In addition, drug therapy is also needed to strengthen lipid lowering, which can use statins such as atorvastatin, cholesterol absorption inhibitors such as ezetimibe, bile acid chelating agent kauleidenamine, etc.; if the effect of oral medication is not good, you can also consider injecting PCSK9 inhibitor iloyuzumab. The specific use of medication should follow the doctor’s instructions, do not take medication arbitrarily. At the same time, we need to pay attention to regular review, regular detection of cardiac function, as well as stent condition. It is recommended to consult a doctor as soon as possible to standardize the diagnosis and treatment.
