The onset of cardiovascular disease is distinctly seasonal, with a higher incidence during the cold season, especially for hemorrhagic ones. The peak time of onset is usually the period between morning and midday adjacent, as indicated by the findings. According to the analytical epidemiological survey study of cerebrovascular diseases, the risk factors of cardiovascular diseases include intervenable factors such as hypertension, heart disease, diabetes, dyslipidemia, etc. Therefore, good disease prevention can reduce the chances of incidence. ”Secondary prevention in the prevention of cardiovascular disease is for patients who have had one or more strokes, i.e., to reduce the risk of stroke recurrence by finding the causes of stroke events and correcting all intervenable risk factors.” Patients in this category should be selected for necessary imaging or other laboratory tests to clarify the type of stroke and associated risk factors in patients who have had a stroke. In the meantime, patients are advised to intervene in platelet aggregation with antiplatelet agents, mainly aspirin, pentoxifylline, reserpine and clobetasol. The incidence of cognitive dysfunction as well as dementia is usually higher in people with the disease; therefore, intervention with aspirin at an early stage can help prevent the development of dementia. In addition, the incidence of depression in patients with cardiovascular disease is about 30% to 50% after the disease, which is an important factor affecting the prognosis of patients. Pharmacological treatment should be chosen for patients who have already experienced depression, with drugs such as 5-hydroxytryptamine reuptake inhibitors like fluoxetine and citalopram preferred, and supplemented with psychotherapy. For the general population, high-risk groups and patients, it is important to strengthen the awareness of self-care, establish a reasonable lifestyle, quit smoking, reduce the intake of alcohol, eat a reasonable diet based on the principles of low energy, low fat, foods rich in high quality protein, carbohydrates, vitamins and trace elements, fresh vegetables and fruits, increase physical activity appropriately, and perform regular physical exercise. Patients at high risk need regular medical checkups to increase their compliance with medication and to make them aware that some common risk factors for stroke, such as hypertension, diabetes and atrial fibrillation, are chronic diseases that must be treated for a long time to be effectively controlled.
