Coronary heart disease refers to the occurrence of atherosclerosis in the coronary arteries, leading to narrowing or blockage of the lumen, causing myocardial ischemia, hypoxia, and necrosis resulting in heart disease. Through different pathological anatomy and pathophysiology, there are five major types, including asymptomatic coronary heart disease, angina pectoris, myocardial infarction, ischemic cardiomyopathy, and sudden death. Angina pectoris is one type of coronary heart disease.

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 what?

Coronary heart disease is the most common type of vascular disease caused by atherosclerosis and is a common disease that harms human health, often occurring in men over the age of forty. Men tend to develop the disease earlier than women. It is defined as atherosclerosis of the coronary arteries, causing narrowing or occlusion of the lumen, leading to myocardial ischemia, hypoxia, or necrosis, and resulting in heart disease. Currently, the diagnostic gold standard for coronary heart disease is coronary angiography. During coronary angiography, the presence of significant stenosis in the coronary artery lumen of more than fifty percent can diagnose coronary artery atherosclerotic heart disease, or coronary heart disease. The pathological anatomy and pathophysiology of coronary heart disease vary, leading to different clinical manifestations. In 1979, the World Health Organization classified it into five types: 1. Asymptomatic myocardial ischemia. 2. Angina pectoris. 3. Myocardial infarction. 4. Ischemic cardiomyopathy. 5. Sudden death. Currently, based on different characteristics of onset and principles of treatment, it is divided into two main categories: First category: Chronic coronary artery disease. Second category: Acute coronary syndrome. Acute coronary syndrome includes unstable angina, non-ST segment elevation myocardial infarction, ST-segment elevation myocardial infarction, and sudden death is also included as a manifestation of acute coronary heart disease.

How long can coronary heart disease last?

Coronary heart disease, although having an annual sudden death rate of about 1%-5%, can significantly reduce the mortality rate with standardized treatment. There is currently no medical prediction on how long someone with coronary heart disease can live, as advances in medicine mean that as long as one undergoes standardized treatment using the most scientific, advanced, and regulated methods, and also pays attention to their lifestyle and conditioning, their lifespan should not be affected.

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.

What are the symptoms of coronary heart disease?

The most typical manifestation of coronary heart disease is angina pectoris, but it can also present as chest tightness, chest pain, paroxysmal tachycardia, fatigue, decreased endurance, a feeling of throat constriction, numbness in the upper limbs, and even symptoms related to the digestive tract such as upper abdominal pain, nausea, and vomiting. Many patients with coronary heart disease do not show obvious symptoms, and the onset might present as myocardial infarction or sudden death, which is very frightening. Therefore, if symptoms of coronary heart disease are noticed, it is crucial to seek medical treatment at a hospital as soon as possible. Middle-aged and elderly people should have regular physical examinations. Young people who stay up late, smoke, or are addicted to video games, among other bad habits, can also develop coronary heart disease, so it is important to be mindful of these behaviors.
