What does functional cardiac discomfort mean?

Functional cardiac discomfort generally refers to cardiac neurosis, i.e. heart-related discomfort that occurs when the heart structure and function are normal.

The specific cause of cardiac neurosis is not yet clear. It may be a clinical syndrome with cardiovascular symptoms mainly caused by mental psychological problems or neurological disorders, such as palpitations, precordial pain, dyspnea, etc. However, cardiac neurosis does not belong to organic heart disease. The patient's heart structure and function are normal, so it will not cause serious health problems. Actively cooperate with doctors for drug or psychological treatment, and the prognosis is generally good.
