How does angina develop? What are the causes of angina?

Angina pectoris is a relatively common heart disease, mainly caused by diseases such as coronary heart disease and high blood pressure, and often causes heart pain, chest tightness, chest distension, etc. In severe cases, symptoms such as brain death may occur, and the impact on people is very large, so it is also very important to understand some of the causes of angina pectoris and prevent it. What are the causes of angina?

1. Overwork.

Overwork is an important cause of angina, and general exertional angina is mainly caused by long-term overload of mental work and staying up late for a long time. In addition, strenuous exercise can also cause angina, after overwork, our heart rate will increase, which will increase the burden on our heart, oxygen consumption will also increase, and eventually cause angina pectoris, etc., generally after a period of rest, the symptoms will be relieved.

2. Emotional.

When the body is in a condition of excessive sadness or overexcitement, these excessive fluctuations will be reflected in the brain, and will induce an increase in heart rate, blood pressure will also rise, and eventually angina pectoris. In severe cases, it can cause a series of symptoms such as coronary heart disease, and reduce the blood supply to the heart, so it is recommended to control your mood at ordinary times.

3. Excessive diet.

Overeating is also a cause of angina, the main manifestation is severe chest pain during eating, and some people are manifested after eating, which is mainly because eating too much leads to the stomach and intestines to consume food and requires a lot of energy, which will increase the burden on the heart for a long time, resulting in a significant reduction in blood supply, and eventually lead to the appearance of angina.

4. Drink too little water.

If you drink too little water, it will increase the blood concentration, so it will reduce the speed of blood circulation in the body, and it will increase the burden on the heart, leading to the appearance of angina.

5. Arrhythmia.

Scientific research has proved that arrhythmia is also an important cause of angina, mainly because arrhythmia will make the body's coronary arteries spasm, and will also block blood vessels, so that blood output will be reduced, and eventually lead to angina pectoris. Generally this symptom is mainly paroxysmal and lasts about 3 to 5 minutes.

You must not smoke or drink alcohol, because smoking and drinking alcohol will cause hardening of coronary blood vessels, and there will be heart pain, increase the speed of the heartbeat, and increase the burden on the liver and heart, which is extremely harmful to the body. It is advisable to drink plenty of water at all times, which can help relieve angina conditions.

Causes of angina.

1. Factors such as coronary atherosclerosis, hypertension, hyperlipidemia, diabetes and smoking cause some components of blood lipids to be deposited on the arterial wall, forming atheroma plaque and narrowing the lumen. When the stenosis exceeds 70, blood flow decreases and myocardial tissue is ischemia, resulting in angina.

Causes of angina.

2. Myocardial oxygen supply and demand balance disorder When physical activity and other reasons require an increase in cardiac workload, the coronary arteries cannot dilate accordingly, resulting in myocardial ischemia causing angina, that is, when the balance of cardiac oxygen supply and demand is impaired, angina pectoris may occur.

Causes of angina.

3. Coronary artery spasm The human body can regulate and control the amount of blood in the myocardium through some nerve and humoral factors. Certain causes of disease and life can cause spastic contraction of coronary arteries, sudden narrowing of the lumen, and temporary insufficiency of the myocardial blood supply and angina. In daily life, there are many indirect causes of angina, such as neuropsychiatric factors, mood changes, anxiety, and grief.

In addition, hypertension and hyperlipidemia, diabetes, excessive physical exertion, and strenuous exercise are also causes of angina.

Heart disease is the most common cause of angina in people. Because when people suffer from heart disease, the coronary arteries in the human body will become narrow, which can easily lead to myocardial dysfunction caused by insufficient blood supply to the heart, and angina symptoms appear.

Angina pectoris is caused by the narrowing of the coronary arteries supplied by the myocardium, which is a symptom of coronary heart disease, generally the most common is retrosternal or precordial pain, which can radiate to the inner side of the left upper arm, neck and shoulder blades, jaw and other parts, when the heart needs more blood, the arteries become narrowed and cannot be supplied, and there will be pain and chest tightness. If the angina coronary artery is not severe, it must be taken seriously. The main cause of angina pectoris is the sudden temporary ischemia and hypoxia of the myocardium caused by insufficient coronary blood supply, and chest discomfort is the main symptom, which may lead to angina pectoris.

Insufficient blood supply and oxygen supply to the myocardium is the main cause of angina**, and the main cause of the decrease in myocardial blood supply is coronary artery disease.

Angina pectoris occurs when there is a contradiction between coronary blood supply and myocardial blood demand due to any reason, and the coronary blood flow cannot meet the needs of myocardial metabolism, resulting in rapid temporary ischemia and hypoxia of myocardium.

Coronary insufficiency, myocardial acute transient ischemia and hypoxia of the clinical syndrome is chronic ischemic heart disease.

The immediate cause of angina pectoris is a lack of blood supply to the heart muscle. The main cause of myocardial insufficiency is coronary heart disease. Sometimes, other types of heart disease or uncontrolled high blood pressure can also cause angina.

If fat in the blood vessels keeps accumulating, plaque can form. If this plaque occurs in the coronary arteries, it can lead to narrowing of the coronary arteries, further reducing their blood supply to the heart muscle, resulting in what is known as coronary heart disease.

Traditional Chinese medicine should be a deficiency of heart yin.
