In principle, patients with cerebral infarction need to take medication for the rest of their lives, which is medically known as secondary prevention. This is because patients with cerebral infarction who discontinue taking medication risk damaging the normal vascular endothelium and forming new thrombi on the surface of the damaged endothelium, thus blocking the cerebral vessels and leading to recurrence of cerebral infarction. For cerebral infarction caused by cardiogenic diseases, if anticoagulant drugs are not persistently taken, new emboli may be formed and dislodged to block large blood vessels, resulting in serious consequences. In principle, patients with cerebral infarction need to take medication for life, and the commonly used drugs include antiplatelet drugs as well as anticoagulants, statins, etc. If patients develop complications such as gastrointestinal bleeding, liver function impairment, myositis, etc. as a result of taking medication, the medication can be suspended. Usually, these complications are transient and patients can recover after symptomatic treatment, but they still need to continue taking the medication. It is not uncommon for patients with cerebral infarction to have a second relapse or even three relapses due to the termination of medication. Therefore, it is important to do a good job of health education for patients with cerebral infarction.
