Patients with cerebral infarction who do not take medication are at great risk and their chances of having a second stroke are increased by 30%. Patients with cerebral infarction need to take medications to promote neurological recovery as well as to control risk factors and prevent recurrence of the infarction during both the acute and recovery periods. If antiplatelet agents, anticoagulants and statins are not taken, the patient’s vascular endothelium cannot be repaired and platelets will continue to collect on the damaged endothelial surface to form blood clots, leading to a second or even third stroke. In addition, antihypertensive drugs and drugs to control blood sugar must also be taken consistently. If they are not taken, high blood pressure and high blood sugar will aggravate atherosclerosis, and at the same time may cause cerebral hemorrhage, renal insufficiency, coronary heart disease, fundus lesions and other diseases, which will cause great harm to the health of patients. Therefore, patients with cerebral infarction must insist on taking medication.
