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 tests are done for coronary heart disease?
The diagnostic tests for coronary heart disease include: electrocardiogram, exercise stress test, Holter monitoring, nuclear myocardial imaging, echocardiography, hematologic tests, multi-slice spiral CT, as well as coronary angiography and intravascular imaging, among others.
Can coronary heart disease be cured?
Can coronary heart disease be cured? Objectively speaking, the current treatment of coronary heart disease mainly focuses on controlling the progression of the disease, relieving symptoms, improving the quality of life, and improving the prognosis, but it cannot completely cure coronary heart disease. Firstly, the cause of coronary heart disease is the major blood vessels supplying the heart, the coronary arteries, undergoing atherosclerosis and narrowing, leading to insufficient blood supply to the heart, ultimately resulting in angina and heart failure. Therefore, the fundamental cause of coronary heart disease is the pathological changes in the coronary arteries, and the reasons and fundamental mechanisms causing these changes are not entirely clear, and are related to factors such as high blood lipids, high blood pressure, high blood sugar, age, smoking, family history, etc. Thus, the main treatment for coronary heart disease currently is to improve lifestyle, quit smoking and limit alcohol consumption, control blood pressure, blood sugar, and blood lipids, and use aspirin or antiplatelet drugs to inhibit the aggregation of platelets and prevent thrombosis.
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.
