[Panic disorder in patients with chest pain and palpitations: an often unrecognized relationship].

The prevalence of panic disorder in patients who present with chest pain or palpitations to a First Heart Aid setting varies in the literature between 0%-59%. In a high percentage of cases, panic disorder is not recognized by the cardiologist in patients who present initially with chest pain or palpitations. Patients with panic disorder have a large and ongoing medical consumption. A selective serotonin reuptake inhibitor and/or cognitive therapy appear to be good treatment of panic disorder in patients who present initially with chest pain or palpitations. A CO2 challenge test elicits the symptoms in patients with panic disorder with high sensitivity and specificity but this test has not been validated in patients who present initially with chest pain or palpitations and in whom the diagnosis 'panic disorder' is not yet established.
