Excessive anxiety about the condition of the heart. Cardiac neurosis typically follows heart surgery or a myocardinal infarction (heart attack), but can also occur occasionally when the person has had no previous heart problems.
A person who has cardiac neurosis undergoes symptoms that are typical of heart disease, such as chest pain and breathlessness, and can be reluctant to work or exercise for fear of having a heart attack. However medical investigation reveals no physical problem.
Psychotherapy (for example cognitive behaviour therapy) can help an affected person to resume a normal active life and overcome the anxiety.
