What are the causes of myocardial infarction

Myocardial infarction is a common heart disease, and everyone should know more about its causes. The causes of myocardial infarction can be analyzed using both Western medicine and Chinese medicine. In fact, more reasons can be attributed to the patient's own habits and lifestyle.

1. Western medicine believes that the main causes of myocardial infarction are as follows:

1. Insufficient myocardial blood supply: On the basis of stenotic coronary artery atherosclerosis, insufficient myocardial blood supply due to excessive load can also cause myocardial infarction.

2. Coronary artery thrombosis: Since many autopsy cases have found that the coronary artery branches supplying the infarct area have stenotic atherosclerosis and occlusive thrombosis, many scholars believe that coronary artery thrombosis is the cause of myocardial infarction. However, the incidence of coronary artery thrombosis in myocardial infarction cases varies greatly from one report to another. Therefore, there is still controversy about the relationship between coronary artery thrombosis and myocardial infarction.

3. Coronary artery spasm: Due to the progress of cardiovascular angiography technology, a breakthrough has been made in the problem of coronary artery spasm. It has been confirmed that variant angina is caused by coronary artery spasm. Some people used coronary angiography to study a large number of transmural myocardial infarction cases and found that the coronary artery occlusion rate decreased with the extension of time after the onset, indicating the relief of coronary artery spasm. Recent studies have shown that severely narrowed coronary arteries can still contract.

2. According to traditional Chinese medicine, the main causes of myocardial infarction are as follows:

1. Elderly and weak body: Acute myocardial infarction often occurs in people over 40 years old, and its incidence rate increases significantly with age. The mechanism is that the yang energy of the aging body gradually declines, the movement of qi and blood is sluggish, and the waste is not easily discharged from the body and is deposited in the blood vessels. Over time, the blood vessels are blocked by inducements (usually cold), forming blood cancer.

2. Suffering from wind diseases: Myocardial infarction combined with hypertension, hyperlipidemia, diabetes, etc., the mechanism is that the chronic disease body, long-term illness and malnutrition, the vital energy is damaged, the heart yang is consumed, over time, the blood vessels are blocked by phlegm.

3. Addiction to fatty, sweet foods, smoking and drinking: Acute myocardial infarction is often caused by addiction to fatty, sweet foods, smoking and drinking. People who are fond of fatty and sweet foods can easily damage their spleen and stomach, leading to spleen deficiency. Spleen deficiency will cause dampness and phlegm to form, and phlegm will block the chest, causing the chest yang to be weak, the blood vessels to stagnate, and blood vessels to be blocked. People who are addicted to alcohol are prone to dampness and phlegm, which block the chest yang and cause blood vessel obstruction. Tobacco is a fire-related substance, which is dry in nature and damages body fluids. Yin deficiency leads to excessive fire, heat disturbs the heart and blood circulation, damages the collaterals, and causes qi stagnation and blood stasis.

4. Stay still more and move less: Most of the causes of myocardial infarction are caused by mental work. If you do little solid labor, your Yang Qi will often not be able to expand, which will damage your spleen over time. Spleen deficiency will produce phlegm and dampness, which will block the chest, cause discomfort in the heart yang, and poor blood circulation, leading to stagnation of blood exchange and qi.
