Retrosternal pain can be caused both by cardiac and esophageal disease. This work presents the results of cardiac and esophageal investigations in 55 patients, who had atypical chest pain. Isolated esophageal disease was found in 45% of the subjects while 14.5% had significant coronary arterial disease. Both diseases were found in 10.9% of the patients and neither disease in 29%. We conclude that esophageal disease is very frequent in patients with atypical chest pain but it does not always completely account for the symptoms. Such patients should, in our opinion, be submitted to an electrocardiographic stress test. If the result is positive or non-diagnostic, coronary cineangiography should be performed, irrespective of the results of esophageal investigations. If the electrocardiographic stress test is negative, coronary investigations can be deferred. Esophageal investigations can account for the symptoms in about half of such cases.
