Why is the incidence of cerebral infarction so high? These 3 factors or 'bane', know early and prevent early

Everyone must have heard of "cerebral infarction" in daily life, which is one of the most common cardiovascular and cerebrovascular diseases in China.

　　According to the content published by the authoritative medical journal The Lancet, the number of new cerebral infarction patients in the world has reached 13.7 million , and the number of new cerebral infarction patients in China has reached 5.51 million , accounting for about 40% of the global total . .

According to statistics, about 2 million　　patients die each year due to cerebral infarction in China . Not only that, cerebral infarction is also one of the main factors leading to disability in patients.

　　In fact, the so-called cerebral infarction refers to the smooth blood vessels that originally supplied blood to the brain. Atherosclerosis occurs due to various factors, and the blood vessels become more and more narrow, affecting the normal blood supply to the brain tissue.

　　Once the carotid artery or vertebral artery is blocked, it will cause ischemic and oxygen necrosis of brain tissue, resulting in cerebral infarction. Clinically, the full name of cerebral infarction: ischemic stroke. So the question is, why is the incidence of cerebral infarction in China so high?

　　In fact, it seems that cerebral infarction is an acute cerebrovascular disease, but it takes quite a long time from healthy cerebral blood vessels to infarction. The following three factors are the main reasons behind the occurrence of cerebral infarction:

1. Vascular risk factors

　　The root cause of ischemic stroke is the formation of thrombus on the walls of blood vessels supplying blood to the brain, which leads to arterial embolism after falling off. It is basically based on atherosclerosis.

　　From a clinical point of view, hypertension, diabetes, and hyperlipidemia are independent risk factors for stroke , of which hypertension is the most important cause, especially for patients with elevated blood pressure in the morning.

　　The study found that morning hypertension is the strongest independent predictor of stroke events, and the risk of ischemic stroke in the early morning is about 4 times higher than other time periods;

2. Gender, age, race

　　Relevant studies have shown that the incidence of stroke in Chinese residents is significantly higher than that of heart disease, which is exactly the opposite of European and American populations. The reason for this may be related to race.

　　In addition, although stroke has shown a trend of younger people, in clinical stroke, middle-aged and elderly patients are still the main patients . Some;

　　3. Bad lifestyle

　　Usually, if a patient has multiple risk factors, such as long-term smoking and alcoholism, unhealthy eating habits, excess weight, lack of exercise , etc. , it will also increase the risk of stroke.

　　This is so because bad habits may lead to increased blood pressure, metabolic disorders , and smoking also accelerates the development of atherosclerosis, which in turn increases the incidence of stroke.

　　In view of the above three reasons, the clinical prevention of stroke has also launched a three-level strategy:

　　Primary prevention : that is, it is mainly aimed at high-risk groups of stroke, actively treats the three high diseases, and conducts relevant physical examinations on a regular basis. In addition, studies have confirmed that quitting smoking and drinking, limiting dietary salt intake, eating more fresh fruits and vegetables, regular physical exercise, and avoiding alcoholism may all reduce the risk of cardiovascular disease;

　　Secondary prevention: This is mainly for patients who have experienced one or more strokes, early diagnosis and early treatment, and prevention of severe cerebrovascular disease. Secondary prevention of cardiovascular disease is also required for patients who already suffer from the three-high disease . These interventions, combined with smoking cessation, can prevent nearly 75% of recurrent vascular events;

　　Tertiary prevention: Patients who have suffered a stroke should strengthen rehabilitation care to avoid continued serious illness.

　　Finally, I would like to remind everyone that although the incidence of stroke is related to many aspects such as age, gender, and genetics.

　　However, it is more affected by acquired factors. Therefore, in order to reduce the incidence of cerebral infarction, it is necessary to actively control the primary disease and improve poor diet and living habits from now on. In addition, patients who have already developed the primary disease also need to be regularly reviewed.
