Coronary heart disease is to some extent a genetic disease. Risk factors for coronary heart disease include controllable risk factors, such as hypertension, hyperlipidemia, hyperglycemia, obesity, smoking, alcoholism, etc., and include uncontrollable factors, such as genetics, age, etc. For patients with a family history of early-onset cardiovascular disease, children have a significantly increased risk of heart disease, especially coronary heart disease, indicating a relationship between coronary heart disease and genetics. In addition, the risk factors of coronary heart disease include hypertension, hyperglycemia and hyperlipidemia, all of which may be related to heredity, so coronary heart disease is to some extent a genetic disease, and it should be noted that the occurrence and development of coronary heart disease is often accelerated by poor lifestyle habits in later life, so attention should be paid to avoid the related risk factors.
