Coronary heart disease has no symptoms.

Coronary heart disease refers to the narrowing or blockage of the coronary arteries, leading to ischemia, hypoxia, or even necrosis of myocardial cells, which is a type of heart disease. Its full name should be coronary artery atherosclerotic heart disease, commonly known as coronary heart disease. Coronary heart disease can be divided into five types: The first type is occult or asymptomatic coronary heart disease. The second type is angina pectoris, the third type is myocardial infarction, the fourth type is ischemic cardiomyopathy, and the fifth type is sudden death. Among these, patients with occult or asymptomatic coronary heart disease may not have obvious symptoms or any symptoms at all, so a person without symptoms does not necessarily mean they do not have coronary heart disease. Whether a patient has coronary heart disease should still be determined by a specialist based on relevant examinations.

What are the symptoms of the early stage of coronary heart disease?

Coronary heart disease refers to the condition where the coronary arteries undergo arteriosclerotic changes, leading to the narrowing or blockage of the vessel lumen, which in turn causes myocardial ischemia, hypoxia, or necrosis, resulting in a series of heart conditions. Some of the early manifestations of this disease often include chest pain triggered by physical activity or emotional agitation. Sometimes it can also manifest as a feeling of suffocation and pain, which often appears as paroxysmal angina or crushing pain, and may radiate to other areas such as the shoulder, upper arm, and fingers. Resting or taking medications like nitroglycerin can significantly alleviate symptoms. Other possible symptoms include fever, sweating, panic, nausea, vomiting, etc.

Is coronary heart disease hereditary?

Coronary heart disease involves genetic factors, but it is not solely due to this factor; multiple factors are involved, including arterial wall cells, extracellular base blood components, and the local hemodynamic environment, all of which can have an impact. Therefore, there is a certain familial aggregation, meaning if there are patients with coronary heart disease in the family, the risk of developing the disease is also increased.

Coronary heart disease is caused by what?

Coronary heart disease is caused by the narrowing or blockage of the coronary arteries due to atherosclerosis, leading to myocardial ischemia and hypoxia. The exact cause of coronary atherosclerosis is not yet clear. Extensive research indicates that the formation of atherosclerosis involves various factors including arterial wall cells, extracellular matrix blood components, local hemodynamic environment, and genetics. Key risk factors include abnormalities in lipoproteins, hypertension, diabetes, smoking, obesity, elevated homocysteine, reduced physical activity, and old age. The condition primarily starts with damage to the endothelium and gradually progresses from there.

What is good for patients with coronary heart disease to eat?

For patients with coronary heart disease, a predominantly vegetarian diet is recommended. The diet should be low in calories, fats, cholesterol, and salt; high in protein, vitamins, and fiber; non-irritating; divided into more frequent, smaller meals; and consist of easily digestible foods. Regular consumption of nutrient-rich, easily digestible foods is advisable, especially those containing high-quality proteins with essential amino acids, B vitamins, and vitamin C. It is important to avoid overeating, restrict salt intake, and remember to include potassium-rich foods. Examples of beneficial foods include beans and their products, potatoes, seaweed, kelp, shiitake mushrooms, other mushrooms, Chinese yam, bamboo shoots, wood ear mushrooms, buckwheat, and bananas. Limit the intake of fats and sugar-rich foods, and opt for foods that can reduce blood lipids, such as milk, sheep's milk, soybeans, green beans, peas, lentils, carrots, cauliflower, hawthorn, kelp, fish, onions, and shiitake mushrooms.
