Coronary heart disease, formally known as coronary atherosclerotic heart disease, is a type of ischemic heart disease caused by the atherosclerosis of the coronary arteries, and one should register with the department of cardiology. Coronary heart disease can cause significant harm to the body and requires treatment under the guidance of a cardiologist in the department of cardiology. Effective medications are used to relieve symptoms, improve myocardial blood supply, and treatments commonly include methods such as dilating the coronary arteries, invigorating the blood, nourishing the myocardium, and regulating blood lipids, to prevent the progression of coronary heart disease.

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.

How to Provide Emergency Aid for a Heart Attack

The cause of coronary heart disease is the formation of atherosclerotic plaques in the coronary arteries, leading to insufficient blood supply to the heart and resulting in symptoms. Therefore, the emergency treatment for a coronary event often involves the use of medications that dilate the coronary arteries to alleviate the symptoms of myocardial ischemia. Commonly used nitrate medications taken sublingually can quickly relieve symptoms of angina. The significance of nitrates lies in their ability to release nitric oxide donors, which can effectively dilate the coronary arteries. This dilation improves blood flow through the coronary arteries and thus corrects symptoms of myocardial ischemia. During an attack, considering sublingual nitrate medication is advisable, provided there is no history of severe hypotension from nitrates, or if there is no hypotension during the attack, under these circumstances, this type of medication can be considered. If any of the above contraindications exist, such as low blood pressure, one might also consider sublingual administration of some traditional Chinese medicine preparations, like emergency pills, which can be used as well.

What is coronary heart disease?

What is coronary heart disease? Let's first explain two definitions: The first is the coronary artery: The coronary artery is the artery that supplies blood to the heart. The heart is shaped like an inverted, slightly flattened cone. If we compare the heart to a person's head, then the coronary arteries on the heart are like a crown situated on top of the head, almost encircling it, hence called "coronary." The second is arteriosclerosis: Lipids in the blood deposit on the inner lining of the arteries, accompanied by the proliferation of certain cells, such as smooth muscle cells and connective tissue, causing thickening of the arterial intima and formation of atheromatous plaques, making the artery walls harden and the lumen narrow. Coronary heart disease refers to heart diseases related to the coronary arteries. It typically refers to coronary arteriosclerosis, thus the definition of coronary heart disease is: the occurrence of arteriosclerosis in the coronary arteries, leading to narrowing or blockage of these vessels, which causes myocardial ischemia, hypoxia or necrosis, and consequently, heart disease.
