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.

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.

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.

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.

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 fruits to eat for coronary heart disease

For patients with coronary heart disease, it is generally recommended to consume seasonal fruits such as hawthorn, apples, kiwis, pineapples, and bananas. Hawthorn contains triterpenoid and flavonoid compounds that can significantly dilate blood vessels and lower blood pressure. Additionally, hawthorn aids digestion and regulates blood lipids and cholesterol levels, benefiting those with coronary heart disease. Research indicates that apples can help prevent the rise of cholesterol and are beneficial against atherosclerosis associated with coronary heart disease. Kiwis are particularly high in vitamins and reportedly help lower cholesterol and triglyceride levels, which is advantageous for preventing atherosclerosis. Pineapples are said to reduce blood lipid release and decrease the incidence of coronary heart disease; however, they can cause "internal heat," so it is advisable for individuals with a phlegm-heat constitution to consume them sparingly. Bananas, rich in carbohydrates and various vitamins, are suitable for people with coronary heart disease, especially those suffering from constipation, as bananas can moisturize the intestines and thus help reduce factors that trigger coronary heart disease.
