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.

Can people with coronary heart disease eat eggs?

Eggs contain rich proteins that are easily digested, absorbed, and utilized by the human body. Eggs also contain a variety of amino acids, including some essential amino acids that the body cannot synthesize on its own and must be ingested through diet. Eggs are beneficial for human growth and development, and patients with coronary heart disease can consume eggs, but they should be mindful of the quantity. Patients with coronary heart disease should adhere to a low-salt, low-fat diet, avoid fatty meats or animal organs, and generally consume fewer foods that are high in cholesterol and fat. Additionally, patients should adjust their lifestyle, follow medical advice, take medications on time, and undergo regular check-ups.

How is coronary heart disease diagnosed?

The routine non-invasive examination for coronary heart disease primarily includes an essential electrocardiogram, as well as echocardiography. Blood tests generally look at cardiac enzymes and the status of troponin to check for any heart muscle damage. In terms of invasive methods, we can perform coronary angiography, which allows us to directly observe the condition of the coronary arteries. The condition of coronary arteries can also now be examined through a non-invasive CT angiography (CTA), which can also reveal any narrowing of the coronary arteries and assess the severity of such narrowing.

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.
