It is possible for a person to be scared of heart disease, and the causative factors of heart disease include genetic factors as well as acquired factors. For people with chronic mental tension and stress, they are prone to heart disease. In addition, for patients with underlying cardiac disease, the relevant triggers, especially excitement and exertion, can easily increase sympathetic excitability, increase heart rhythm and blood pressure, and trigger an acute attack of heart disease. For ordinary people as well as people with underlying heart disease, it is not recommended to be excessively frightened and mentally stressed for a long time, as these states can easily lead to the occurrence and development of the disease.
