Cerebral infarction is a chronic disease with “high morbidity, high mortality, high disability, high recurrence rate and many complications”. According to statistics, nearly 2 million patients die from cerebral infarction every year in China, while 75% of the surviving patients lose their working ability to varying degrees and 40% become seriously disabled. Moreover, cerebral infarction is a disease that is prone to recurrence and often worsens with each recurrence, posing a serious threat to the health and life of patients. It has a serious impact on the quality of life of patients and their families. Therefore, for patients with cerebral infarction, how to prevent recurrence and reduce the recurrence rate has become an issue of great importance and widespread concern. So, how to avoid recurrence in patients with cerebral infarction? 1, regular review is very important: through the national “973” subject of cardiovascular and cerebrovascular disease research confirmed that no matter what kind of risk factors cause vascular damage, and finally lead to cardiovascular and cerebrovascular infarction, the process of thrombotic factors must increase, causing ischemic ischemic factors will also increase, especially in the blood vessels already existed in the arteries The ischemic factor of ischemia will also be increased, especially if there are already atheromatous plaques and certain stenosis in the blood vessels. It is especially important to evaluate the early warning in order to guide our timely intervention and treatment. 2. Anti-platelet drug therapy: The pathological basis of cerebral infarction is cerebral atherosclerosis. Regardless of the degree of recovery after suffering from cerebral infarction, most of its patients still have the source of emboli inside their blood vessels that cause infarction, such as atherosclerotic plaques, etc. This makes it very necessary to carry out antiplatelet intervention therapy: enteric aspirin, 75-150 mg, divided into three oral doses daily, or bye aspirin, 100 mg, taken orally once a day. Other lipid-lowering drugs can be taken orally according to the blood lipid level. 3, scientific application of antihypertensive drugs: is also one of the important means to ensure the reduction of cerebral infarction patients, keep blood pressure stable: the process of medication should adhere to regular monitoring of blood pressure, it is best to take controlled-release lowering drugs to ensure that 24-hour blood pressure is stable, so as not to cause blood pressure fluctuations, resulting in the exfoliation of intravascular plaque causing embolism, if patients with severe vascular stenosis, blood pressure should not be lowered too low, otherwise it will lead to cerebral infarction occur. 4, avoid overwork or rest: mental tension, emotional excitement, irregular life, fatigue, tension, excitement or rest is easy to cause blood pressure fluctuations, bad mood, especially anger or long-term depression, anxiety, can cause vascular neuromodulation, or lead to cerebral vasoconstriction, or hemodynamic changes, causing the recurrence of cerebral infarction. 5, pay attention to quit smoking and alcohol: nicotine in cigarettes can damage the intima, and can cause small blood vessel constriction, narrowing of the lumen, and therefore easy to form thrombosis. A large number of references to strong alcohol, harmful to the blood vessels. According to the survey, alcohol abuse is one of the causes of cerebral infarction. 6, pay attention to avoid cold: cold stimulation, not only can cause small blood vessel constriction, but also cause an increase in blood viscosity, easy to induce cerebral infarction, so winter is often the high incidence of cerebral infarction season, this season is particularly important for secondary prevention of cerebral infarction. 7, pay attention to avoid high-fat, high-calorie diet: If you continuously enter a long-term high-fat, high-calorie diet, blood lipids can be further increased, blood viscosity increases, atherosclerotic plaque is easy to form or increase, which eventually leads to the recurrence of cerebral infarction. 8. Prevent dehydration caused by violent vomiting and diarrhea: Since dehydration can increase blood viscosity, dehydration caused by various reasons can trigger the recurrence of cerebral infarction, and patients and their families should be alert to this, and early treatment should be provided if there is a tendency of dehydration. Patients suffering from cerebral infarction, in the process of prevention and treatment, should pay attention to avoid the above-mentioned triggers, do some physical activities properly, be emotionally stable, adhere to reliable medication, and review regularly, so as to be able to block and prevent the occurrence of cerebral infarction disease in a more ideal way.
