(1) Scientific understanding of coronary heart disease is necessary. First of all, we should understand the composition of the heart, the causes of coronary heart disease, and common triggering factors with the help of doctors, so that patients have a correct understanding of coronary heart disease, and then eliminate the abnormal mentality of “why do I have coronary heart disease?” The abnormal mentality of “why do I have coronary heart disease?”, establish a normal mentality that can live with the disease, reduce unnecessary stress, and help prevent myocardial infarction, sudden death and other cardiac accidents. (2) When things go wrong, we should be calm and try to avoid emotional excitement. As you know, emotional excitement may induce angina and myocardial infarction. Those who are quick-tempered, nosy, and prone to sulking must often remind themselves that they should be calm and talk in a calm manner. If the mood is difficult to keep calm for a while, should go away to another place, a change of environment, or appropriate labor or sports activities to relieve and release the inner pain. (3) to achieve “peaceful coexistence” with family members and neighbors. During the day, we should talk more, more exchange of ideas, and care for each other. Forgiveness of others, do not be calculating, do not lose your temper over trivial matters, adding to the burden of the mind and body.
