From clinical observation, coronary heart disease does have a family genetic tendency, the specific mechanism is not clear, it may be related to the following factors.1. Coronary heart disease itself has a genetic tendency. If a patient’s father has coronary heart disease before the age of 55 and the patient’s mother has coronary heart disease before the age of 65, both belong to the family history of early-onset coronary heart disease, the risk of coronary heart disease in children will be particularly high. If the parents suffer from coronary heart disease at a young age, the risk of coronary heart disease in children will be even higher. 2. Risk factors for coronary heart disease are inherited. Common risk factors for coronary heart disease, such as hypertension and diabetes, have a clear genetic predisposition. Especially in the case of hypertension, if the parents have high blood pressure with coronary heart disease, the children can also have high blood pressure with coronary heart disease. 3, personality inheritance. For example, if parents have type A personality, children are also likely to have type A personality, and patients with type A personality tend to be overly nervous and have a high prevalence of coronary heart disease.
