A while ago, I saw a middle-aged male patient with a past history of hypertension and a history of smoking and drinking. The patient said to me: “Doctor, I came to the hospital as fast as I could. I heard that you have the most experience in treating this disease, so I came to you directly. Like this patient, many patients with cerebrovascular diseases are usually negligent in self-restraint, and when they have an attack, they think: as long as they arrive at the hospital as fast as possible, ask the most famous doctors to treat them, and use the best and most expensive drugs, they can definitely recover their health. Of course, it is undeniable that time, medical skills and drugs are important for the treatment of cerebrovascular diseases. However, I do not know, cerebrovascular disease, prevention is the most important thing! So, many patients will ask: How to prevent cerebrovascular disease? Prevention of cerebrovascular disease is to prevent or slow down the damage to cerebrovascular blood vessels by intervening in advance on the risk factors that may cause cerebrovascular disease. Common clinical risk factors that may cause cerebrovascular disease are: hypertension, heart disease, diabetes, dyslipidemia, smoking, alcohol consumption, obesity, carotid artery stenosis and other risk factors. 1. For patients with hypertension. Should be low salt diet, strictly limit the salt intake, the amount of salt per person per day to not more than 6 grams is appropriate; appropriate physical exercise, reduce weight; strengthen blood pressure monitoring, and under the guidance of physicians to take antihypertensive drugs. 2. For patients with heart disease. Should be actively treated and intervene in advance. 3, diabetic patients should first control diet and strengthen physical exercise. Those whose blood sugar control is still unsatisfactory in 2 to 3 months should be treated with oral hypoglycemic drugs or use insulin. What’s more, they should actively treat hypertension, control weight and lower cholesterol level. 4.For patients with dyslipidemia. Especially for patients with secondary dyslipidemia, most of them have other risk factors such as hypertension, diabetes, smoking, etc. In addition to controlling the original disease, they should actively change their unhealthy lifestyles and review their blood lipids regularly. If necessary, take lipid-lowering medication under the guidance of a physician. 5. Frequent smoking is a recognized risk factor for ischemic stroke. Its pathophysiological effects on the body are multifaceted, mainly affecting the systemic vascular and blood system such as: accelerating atherosclerosis, increasing fibrinogen levels, prompting platelet aggregation, and lowering HDL levels. Chronic passive smoking may also increase the risk of stroke. Evidence from population studies has shown that alcohol intake has a direct dose-related effect on hemorrhagic stroke. Therefore, smoking and alcohol should be abstained from. 6. For patients with carotid artery stenosis. Treatment should be directed by a physician based on the improvement of relevant investigations. 7. Overweight and obese people should adopt a healthy lifestyle, change their diet and exercise habits and adhere to them for a long time. If necessary, medication or surgery should be used. 8. For patients who have had a stroke. Patients with recurrent TIA are at great risk of complete stroke and should be treated with great care. 9. In addition, risk factors such as hyperhomocysteinemia, metabolic syndrome, lack of physical activity, unreasonable diet and nutrition, oral contraceptives, and procoagulation can also increase the risk of cerebrovascular disease and should be actively intervened. The Yellow Emperor’s Classic of Internal Medicine says, “The sage does not treat the already diseased to treat the untreated, and does not treat the already disordered to treat the untreated.” That is, to intercept the development of a disease when it is not onset by intervening in its risk factors, thus preventing the occurrence of the disease. There are many risk factors for cerebrovascular diseases, and many patients do not care about their prevention and wait until the onset of the disease before going to the hospital for treatment. Only by paying attention to prevention is it possible to reduce the occurrence of cerebrovascular disease.
