What are the risk factors for stroke? The most important risk factors for stroke in China are:

There are eight risk factors for stroke: hypertension, hyperlipidemia, hyperglycemia, atrial fibrillation, smoking, alcoholism, inactivity, and obesity. If all three risk factors are met, then a person at high risk of stroke can be judged.

Experts recommend that high-risk groups should go to a doctor for a basic check-up.

Research evidence suggests that more than 80% of strokes can be prevented early through risk factor control. Experts point out that there are two levels of stroke prevention: primary prevention and secondary prevention.

In addition to healthy lifestyle habits, experts point out that once a stroke occurs, the risk of recurrence is also high, and secondary prevention of stroke is required.

<> experts point out that the main manifestations of stroke can be judged by the following phenomena.

sudden drooling at the corner of one side of the mouth, inability to speak, or slurred speech;

Sudden loss of strength in one arm or leg (inability to lift, inability to walk or stand, unsteady holding of things) on one side (left or right);

sudden onset of numbness or lack of sensation on one side of the face;

Sudden dizziness, blurred vision, or double vision;

sudden, severe headache;

Sudden loss of consciousness.

Risk factors for stroke include: age, genetics, hypertension, arrhythmias, fundus arteriosclerosis, smoking, alcohol consumption, obesity, oral contraceptives, dietary factors such as high salt, meat, high animal fat, strong coffee, strong tea, excessive physical activity, etc.

High blood pressure: hypertension is the most risk factor for stroke in the Chinese population, especially in the early morning. The study found that the risk of ischemic stroke in the early morning hours was four times higher than in other periods, and for every 10 mm Hg increase in early morning blood pressure, the risk of stroke increased by 44%.

Transient weakness, transient visual disturbances, intermittent pulse-like tinnitus, frequent yawning, headaches: the above symptoms should also be paid attention to frequently, because these signal factors are not taken seriously enough, but they are indeed risk factors for stroke.

Sleeping snoring: People normally hold their breath for up to 40 seconds, but the pause in breath caused by snoring can last for up to 1 minute or even 2 minutes. Therefore, during this period, you cannot take in enough oxygen, which is very easy to cause cerebral hypoxia, resulting in cerebral stroke.

No scarf, improper exercise, improper massage: windproof and warm, appropriate physical exercise, and regular physiotherapy massage can prevent the incidence of stroke.

In addition, the lack of physical examination habits is also an important factor causing sudden stroke in "healthy people". Therefore, we should be vigilant and develop a good habit of regular physical examination.

There are many risk factors for stroke, which are usually related to age, smoking, mental factors, hypertension, hyperlipidemia, diabetes, hyperhomocysteinemia, cardiovascular disease, family hereditary factors, etc., which can be manifested as sudden fainting, unconscious, accompanied by symptoms such as crooked mouth and eyes, and poor speech.

1. Aging: It is the main risk factor for stroke, that is, aging is an important risk factor for stroke, and arteriosclerosis occurs with age, which is easy to block blood vessels and lead to stroke, which is a natural process and cannot be reversed;

2. Smoking: It can not only cause lung diseases, such as lung cancer, but also an important risk factor for stroke, mainly because the metabolites of nicotinic can cause vasospasm, sclerosis, stenosis, plaque, resulting in cerebral ischemia, hypoxia or obstruction, resulting in stroke;

3. Mental factors: due to mood fluctuations, it is easy to cause hemodynamic instability, leading to stroke, so patients with anxiety, irritability, insomnia, and mental and psychological diseases have a relatively high probability of stroke;

5. Hyperlipidemia: it can accelerate the progression of atherosclerosis, cause vascular stenosis, and cause stroke;

6. Diabetes: due to high blood sugar, it can cause the speed of arteriosclerosis to accelerate, which can lead to stroke;

7. Hyperhomocysteinemia: due to the increase of homocysteine, it can accelerate the rate of atherosclerosis, cause stroke, and increase the risk of stroke in patients;

8. Cardiovascular diseases: coronary heart disease, aortic dissection, internal carotid artery dissection and heart disease are also prone to stroke, which are the main risk factors for stroke in young people;

9. Familial hereditary factors: usually there is a history of stroke among family elders, and the incidence probability will increase, and stroke may occur or aggravate stroke;

10. Other factors: including infectious factors, especially syphilis infection, which can affect blood vessels, lead to vasculitis, etc., and aggravate the risk of stroke.

In daily life, patients should maintain good living habits, avoid controllable risk factors such as smoking and drinking, have regular work and rest, and eat a reasonable diet to reduce the occurrence of cardiovascular and cerebrovascular diseases and prevent stroke. In addition, patients also need to increase the amount of activity, maintain emotional stability, avoid overwork, and regular physical examinations, as early as possible, as early as possible.

Stroke is a common neurological disease, and its morbidity and mortality account for a high proportion in China, which brings a serious burden and impact to patients and society. At present, the most important risk factor for stroke in China is hypertension, which accounts for more than 70% of stroke patients.

Hypertension refers to a systolic blood pressure of 140 mmHg or diastolic blood pressure of 90 mmHg in a quiet state, which is an important risk factor for stroke. Hypertension can cause vascular endothelial cell damage and blood-brain barrier damage, resulting in thickening of cerebral blood vessel walls, lumen narrowing and thrombosis, thereby causing cerebrovascular lesions and stroke.

In addition to high blood pressure, some other risk factors may also increase the risk of stroke, such as diabetes, hyperlipidemia, smoking, alcohol consumption, obesity, unhealthy diet, lack of exercise, etc. These risk factors can directly or indirectly affect the health of cerebrovascular diseases, leading to cerebrovascular lesions and strokes.

In order to prevent stroke, we need to pay attention to the control and management of risk factors. First of all, it is necessary to maintain a healthy lifestyle, such as quitting smoking and limiting alcohol, controlling diet, maintaining an appropriate weight, increasing exercise, etc. At the same time, it is necessary to conduct regular physical examinations to detect and develop chronic diseases such as hypertension, diabetes, and hyperlipidemia in time to avoid them developing into high-risk factors for stroke.

In addition, it is also important to pay attention to mental health, avoid excessive tension and stress, and maintain a good state of mind and mood. Through scientific preventive measures, the risk factors of stroke can be effectively reduced, and the occurrence of stroke can be prevented and reduced.

Risk factors for stroke include the following:

1. Hypertension is the most controllable risk factor, and both systolic blood pressure and diastolic blood pressure are independently related to the risk of stroke.

2. Smoking increases the risk factor of stroke.

3. Blood lipids, lowering blood lipids can reduce the risk of cerebrovascular disease.

Fourth, alcohol consumption, heavy drinking is associated with an increased risk of stroke, moderate drinking may have no effect or may have a mild protective effect.

5. Antiplatelet **, reduce stroke and other cerebrovascular lesions in high-risk patients, the optimal dose is currently unknown, the acceptable range is 30-1300 mg d, and the recommended first dose is 325 mg d.

6. Carotid artery stenosis is an important risk factor for ischemic cerebrovascular disease, which is mostly caused by atherosclerosis.

The main intervention factors for stroke include the following:

1. Hypertension: Usually among hypertensive patients, the risk of cerebrovascular events will increase by about 40 to 50 percent for every 10 mmHg increase in systolic blood pressure and 5 mmHg increase in diastolic blood pressure at a higher than normal level;

2. Dyslipidemia;

3. Diabetes: Arteriosclerosis occurs earlier and is more common in diabetic patients, and the risk of ischemic stroke in diabetic patients will increase by three times;

4. Atrial fibrillation: Atrial fibrillation is also common in cardiology patients;

5. Asymptomatic carotid artery stenosis: if the number of patients with asymptomatic carotid artery stenosis is greater than 70%, it needs to be treated;

6. TIA: that is, transient cerebral ischemia, about 1 3 patients with complete stroke have a history of TIA;

7. Smoking, drinking, metabolic syndrome, hyperhomocysteinemia, migraine, obesity, overweight, lack of physical exercise, insufficient nutritional intake and other factors can also cause stroke.

What causes stroke?

The risk of stroke with the increase of systolic or diastolic blood pressure is a linear increase in the risk of stroke, and the incidence of stroke in the population increases with the increase of systolic blood pressure and diastolic blood pressure. The incidence of stroke increases with age. The risk of stroke is related to the level of elevated blood pressure.

The geographical distribution of stroke incidence and prevalence is consistent with that of hypertension. Systematic promotion of antihypertensive** is associated with a decrease in stroke mortality and morbidity.

Diabetes accelerates atherosclerosis, and the effects are systemic. Diabetes can more than double the risk of stroke, and about 20% of people with diabetes will eventually die from a stroke. For those with prediabetes, elevated fasting blood sugar levels also increase the risk of stroke.

High cholesterol and hyperlipidemia.

The risk of hyperlipidemia to cerebrovascular disease is not as obvious as that of coronary heart disease, but the simultaneous increase of hyperlipidemia and low-density lipoprotein concentration is the most important risk factor for ischemic stroke, especially in young men.

Transient ischemic attack (TIA).

Most scholars believe that TIA is a risk factor for all types of stroke, especially ischemic stroke. About 30% of patients with complete stroke have a history of TIA, and about 1 in 3 patients with TIA will develop or recur complete stroke sooner or later.

The change of obese body weight is often related to the change of blood pressure, and obese people who exceed the standard body weight by more than 20% have a significantly increased risk of hypertension, diabetes and coronary heart disease, and hypertension and coronary heart disease are important risk factors for stroke, and obesity can be considered as an indirect risk factor for stroke.

Smoking and drinking.

The risk of stroke in men who smoke a lot is almost three times higher than that of non-smokers, and there is a dose-response relationship between smoking and cerebral infarction. Encouraging smoking cessation is one of the measures to reduce the risk of stroke. Whether it's acute drunkenness or chronic alcoholism. It is an important risk factor for stroke.

Vascular risk factors.

The most common cause of stroke is a small emboli on the lining of the blood vessels supplying the brain, which fall off and cause arterial-arterial embolism, known as ischemic stroke. It may also be caused by cerebrovascular or thrombotic hemorrhage, which is a hemorrhagic stroke. Patients with coronary heart disease and atrial fibrillation are prone to mural thrombosis, which can block cerebral blood vessels and lead to ischemic stroke.

Poor lifestyle.

There are often multiple risk factors at the same time, such as smoking, unhealthy diet, obesity, lack of moderate exercise, excessive alcohol consumption, and high homocysteine; and the presence of underlying medical conditions such as hypertension, diabetes, and hyperlipidemia. will increase the risk of stroke.

Factors such as gender, age, ethnicity, etc.

Studies have found that the incidence of stroke in the Chinese population is higher than that of heart disease, which is contrary to that in Europe and the United States.

There are many risk factors for stroke, which are usually related to age, smoking, mental factors, hypertension, hyperlipidemia, diabetes, hyperhomocysteinemia, cardiovascular disease, family hereditary factors, etc., which can be manifested as sudden fainting, unconscious, accompanied by symptoms such as crooked mouth and eyes, and poor speech.

1. Aging: It is the main risk factor for stroke, that is, aging is an important risk factor for stroke, and arteriosclerosis occurs with age, which is easy to block blood vessels and lead to stroke, which is a natural process and cannot be reversed;

2. Smoking: It can not only cause lung diseases, such as lung cancer, but also an important risk factor for stroke, mainly because the metabolites of nicotinic can cause vasospasm, sclerosis, stenosis, plaque, resulting in cerebral ischemia, hypoxia or obstruction, resulting in stroke;

3. Mental factors: due to mood fluctuations, it is easy to cause hemodynamic instability, leading to stroke, so patients with anxiety, irritability, insomnia, and mental and psychological diseases have a relatively high probability of stroke;

5. Hyperlipidemia: it can accelerate the progression of atherosclerosis, cause vascular stenosis, and cause stroke;

6. Diabetes: due to high blood sugar, it can cause the speed of arteriosclerosis to accelerate, which can lead to stroke;

7. Hyperhomocysteinemia: due to the increase of homocysteine, it can accelerate the rate of atherosclerosis, cause stroke, and increase the risk of stroke in patients;

The first risk factor is smoking, whether active or passive, which can significantly increase the risk of stroke, which is an independent risk factor for stroke. Therefore, to prevent stroke, you must pay attention to quitting smoking.

The second risk factor is hypertension, which is also an important risk factor for cerebrovascular diseases such as cerebral infarction and cerebral hemorrhage.

The third risk factor should be diabetes mellitus, and hyperlipidemia should be noted. If you have these diseases, you will also have a significantly increased risk of stroke.

In addition, genetic factors, age, misuse of other drugs, and hematologic abnormalities are also risk factors.

Stroke refers to a clinical syndrome in which cerebrovascular disease induces narrowing, occlusion or rupture of arteries in the brain, resulting in acute cerebral blood circulation disorder. It is divided into ischemic stroke and hemorrhagic stroke. A variety of causes are associated with stroke onset:

Vascular wall lesions, cardiac and hemodynamic changes, blood composition and hemrheological changes, other**, etc.
