How does coronary heart disease arise and how does coronary heart disease develop?

Due to abnormal lipid metabolism, the lipids in the blood are deposited on the originally smooth arterial intima and some athero-like lipids accumulate in the arterial intima to form white plaques, which gradually increase and cause the arterial lumen to narrow, so that the blood flow is blocked, resulting in cardiac ischemia and angina. If plaque on the artery wall ulcerates or ruptures, a blood clot can form, completely interrupting blood flow throughout the blood vessel, causing acute myocardial infarction or even sudden death. Risk factors for the development of coronary heart disease are:

Age and sex, family history, dyslipidemia, hypertension, diabetes in the urine, smoking, overweight, obesity, gout, inactivity, etc.

1) Causes of coronary heart disease.

Because the heart is constantly beating, it needs a large amount of energy to flow continuously, and the energy and oxygen it needs come from the coronary arteries, it is conceivable that if the coronary arteries are narrowed or occluded, the myocardium can not get blood and oxygen, and damage and even necrosis will inevitably occur.

2) Why do coronary arteries narrow and occlude?

There are many causes of coronary artery stenosis and occlusion, the most common of which is atherosclerotic plaque. The so-called atherosclerotic plaque is a kind of sclerotic plaque, which looks like the rice porridge we usually boil, which protrudes into the lumen of the blood vessels, causing narrowing or even occlusion of the blood vessels, just like the water pipe or kettle spout is blocked by the scale that has gradually accumulated over the years, resulting in a decrease in blood flow to the myocardium and insufficient oxygen supply, which becomes coronary atherosclerotic heart disease, which is what we often call coronary heart disease.

The causes of coronary heart disease are thought to be related to hypertension, hyperlipidemia, hyperviscosity, diabetes, endocrine dysfunction, and advanced age.

1. Age and gender: The incidence of coronary heart disease increases after the age of 40, and the incidence rate of women before menopause is lower than that of men, and it is equal to that of men after menopause.

2. Hyperlipidemia: In addition to age, lipid metabolism disorder is the most important factor in coronary heart disease.

3. Hypertension: Hypertension is closely related to the formation and development of coronary atherosclerosis.

4. Smoking: Smoking is an important risk factor for coronary heart disease and the single most avoidable cause of death. There is a clear dose-response relationship between coronary heart disease and smoking.

5. Diabetes: Coronary heart disease is the cause of all deaths and hospitalization rates of juvenile diabetic patients

6. Obesity: It has been identified as the primary risk factor for coronary heart disease, which can increase the mortality rate of coronary heart disease.

7. Sedentary lifestyle: The risk of coronary heart disease and death will double in people who do not like to exercise.

8. There are still genetics, drinking, environmental factors, etc.

This shows that champions are prone to heart disease.

Coronary heart disease is the abbreviation of coronary atherosclerotic heart disease, when one or more atherotic plaques appear in the coronary arteries cause narrowing of blood vessels, the heart blood supply is blocked, which will cause myocardial ischemia, hypoxia, chest tightness, chest pain. Coronary atheroma formation is cumulative over time, and the following factors can lead to coronary heart disease:

1. Age, with the increase of age, coronary atherosma is gradually formed.

2. Gender, female estrogen has a certain protective effect on blood vessels, so the incidence of coronary heart disease in early women is lower than that of men. However, as women age, the secretion of estrogen in their bodies gradually decreases, and the incidence of coronary heart disease in women after menopause is comparable to that of men.

3. Genetic factors are involved, that is, genes, parents have coronary heart disease, and the risk of coronary heart disease in their children will be relatively high.

4. Hypertension, diabetes mellitus, and hyperlipidemia are also risk factors for coronary heart disease;

5. Smoking, the nicotine in smoke has a damaging effect on vascular endothelial cells and can cause blood vessel thrombosis.

Coronary heart disease is particularly easy to cause myocardial ischemia, so it is necessary to go to the hospital for examination in daily life, so that coronary heart disease can be detected. Coronary heart disease is actually a relatively common disease, and such a disease is also very serious, and may also affect your physical health.

How should coronary heart disease be detected?

You can also check this information on the Internet, because coronary heart disease is also a very serious disease, and if the condition is more serious, then surgery may be required. Therefore, you must pay attention to your diet, if you feel that your heart often has pain, and there are symptoms of vomiting, then you must pay attention. Therefore, everyone must protect themselves, and they must also pay attention to their own safety at this time.

What should be done?

You should also pay attention to these problems in your life, and protect yourself at this time. If you have such symptoms, then you should go to the hospital for a check-up, and you must take care of yourself at this time, so many elderly people will have such problems, but there is no need to feel too nervous. In life, everyone should also pay attention to these problems, and at this time, we must also work hard to change our bad habits.

Coronary heart disease is a very serious disease, and many elderly people are prone to this disease.

SummaryThere is no need to feel too anxious, and you may encounter similar things in your life. So there's no need to feel too nervous, and you should plan ahead at this time. If you want your life to be very good, then you must also care about these problems, and you must also change your bad behavior habits, and you must go to the hospital to do relevant examinations, so you must change yourself, and you must pay attention to your diet, and you must pay attention to your diet health.

The pace of life in modern society is getting faster and faster, and coronary heart disease has long been not only a "geriatric disease", but also a trend of younger people. What are the causes of coronary heart disease? Let's go through them one by one.

1. Age and gender factors. Studies have found that the incidence of coronary heart disease is higher after the age of 40 than before the age of 40. There are also differences in the incidence of coronary heart disease between men and women.

2. Blood lipid factors. Dyslipidemia exists in the occurrence of many coronary heart diseases, and lipid metabolism disorders are closely related to the occurrence of coronary heart disease. The higher the LDL, the greater the risk of coronary heart disease.

3. Athesclerosis. Atherosclerosis is the most fundamental cause of coronary heart disease. Atherosclerosis will cause narrowing of blood vessels, obstruction of blood transportation, and insufficient oxygen in the blood, which can easily cause cardiovascular diseases such as chest tightness and chest pain, and blood vessel rupture.

4. High blood pressure. Long-term hypertension can easily lead to atherosclerosis, which is closely related to the occurrence of coronary heart disease.

5. Smoking. Smoking poisons the cardiovascular system in humans. On the one hand, some substances in tobacco may cause a heart to beat faster and blood pressure higher; On the other hand, the process of smoking produces carbon monoxide, which causes a lack of oxygen in the blood, and the blood cannot properly transport substances that benefit the body, which can cause atherosclerosis.

Risk factors for coronary heart disease include modifiable and non-modifiable risk factors. Understanding and intervening in risk factors can help prevent and treat coronary heart disease.

Modifiable risk factors include hypertension, dyslipidemia (high total or low density lipoprotein cholesterol, high triglycerides, low high-density lipoprotein cholesterol), overweight Obesity, high blood glucose diabetes, unhealthy lifestyle including smoking, unreasonable diet (high fat, high cholesterol, high calories, etc.), physical inactivity, excessive alcohol consumption, and psychosocial factors. Non-modifiable risk factors are:

Gender, age, family history. In addition, it has been associated with infections such as cytomegalovirus, Chlamydia pneumoniae, Helicobacter pylori, etc.

The onset of coronary heart disease is often associated with seasonal changes, emotional agitation, increased physical activity, satiety, heavy smoking, and alcohol consumption.

Coronary atherosclerotic heart disease is also referred to as coronary heart disease, and the coronary arteries supply blood to the heart like a hat. The coronary arteries are blood from the thick arteries and gradually transported to the capillaries, giving nutrients to each heart muscle cell in the heart. If the large artery above is narrowed or blocked, it will cause ischemia and necrosis of many cardiomyocytes.
