Prognosis and gender differences in chest pain patients discharged from an ED.

A large proportion of patients evaluated for chest pain in the emergency department (ED) will be sent home because the probability of acute myocardial infarction, unstable angina, or other severe disease processes is determined to be sufficiently low. Patients who came to the ED at Sahlgrenska Hospital, Göteborg during a 21-month period because of chest pain were registered and followed up for one year. Survivors after one year were asked to complete a mailed questionnaire regarding different kinds of symptoms. Of 5,362 patients evaluated in the ED, 2,175 were sent home on their first visit. Fifty-four percent were men and 46% were women. The one-year mortality rate was 3% in men and 3% in women. Recurrent chest pain, dyspnea, and psychological symptoms were more frequently reported by patients with known cardiac disease than by patients without cardiac disease. Female patients with and without cardiac disease reported significantly more frequent recurrent chest pain, dyspnea, and psychological and psychosomatic complaints than male patients with and without cardiac disease. These data suggest that there are specific gender differences between men and women who are discharged from the ED after being evaluated for chest pain. In particular, psychological gender differences may exist and need to be addressed when evaluating patients with chest pain.
