The causes of stroke

Jun 28, 2021

The causes of stroke are as follows:

1. Age: Just like many other diseases, stroke is inseparable from the aging and degeneration of the human body. The older the person, the higher the probability of the disease. Especially the elderly around 60 years old have poor physical fitness, and most of them also suffer from other diseases, such as high blood pressure and high blood lipids, so they are more likely to get strokes than young people.

2. Hypertension: A number of studies have confirmed that hypertension is the most important risk factor for stroke. Hypertension, high-salt diet and high-dose aspirin are all triggers of cerebral hemorrhage, but high-salt diet and high-dose aspirin can only work through high blood pressure. Most people who do not have high blood diet are not high-salt and do not have high blood pressure. People do not need to take high-dose aspirin, so the risk of high blood pressure is twice that of a high-salt diet and high-dose aspirin. Controlling blood pressure can effectively reduce the possibility of stroke.

3. Smoking: Smoking is a frequent visitor on the list of disease triggers. It is also one of the triggers of stroke, second only to age and high blood pressure. Quitting smoking in time has a preventive effect on stroke, especially high blood pressure under 60 years of age. Patients, or those with other comorbidities such as cardiomyopathy, diabetes, and hyperlipidemia, should effectively quit smoking.

4. Drinking: Alcohol has always been something that people love and hate. It is not as harmful and unhelpful as tobacco. Appropriate drinking can reduce thrombosis, but at the same time it can promote platelet aggregation, promote coagulation reaction, and cause cerebral vasospasm. It is one of the risk factors for stroke.

In particular, moderate and heavy drinking can increase the incidence and mortality of middle-aged people with ischemic stroke. Excluding the age factor, the possibility of stroke in people who drink moderately or heavily is about 2.5 times higher than that of non-drinkers. Therefore, drinking in moderation is necessary, with a small drink for pleasure and a large amount of drinking to hurt the body.

5. Cardiovascular disease: Heart disease, such as rheumatic heart disease, coronary heart disease, heart failure, atrial fibrillation, etc., especially those with arrhythmia or myocardial infarction, are risk factors for ischemic stroke.

6. Diabetes and blood glucose concentration: Diabetes and blood glucose concentration are also risk factors for stroke. As shown by scientific statistics, the incidence of stroke in diabetic patients is 1549.05 per 100,000; the incidence of non-diabetic patients is 333.00 per 100,000. The difference is very significant.

7. Dyslipidemia: Dyslipidemia is always called a "quiet killer", and it tends to silently increase the concentration of "bad cholesterol" in the blood. "Bad cholesterol" is deposited on the arterial wall for many years, gradually causing Arteriosclerosis. Once the arteries are hardened and lack the elasticity they should have, there is a risk of rupture at any time.

8. Pregnancy: High concentrations of estrogen can promote the adhesion and proliferation of platelets, leading to changes in certain coagulation factors and blood vessel walls, which may induce stroke.

In the 1960s and 1970s, there was still a view that oral contraceptives were a risk factor for ischemic stroke, but recent studies have shown that oral low-dose contraceptives do not increase the risk of stroke.
