A 53 year old patient was hospitalized because of retrosternal oppression which was unrelated to effort and recurred in the early morning hours. An esophageal diverticulum and a hiatal hernia were found. The patient had complaints in spite of medical therapy and an operation was performed because of his oesophageal disorders. After operation the patient had the same pain. A cardiologist was asked, who suggested Prinzmetal variant angina. During arteriography coronary artery disease was found. Coronary bypass surgery was indicated and performed, after that procedure the patient was and remained free of any complaints. This observation reaffirmed Prinzmetal original statement "The key to the diagnosis ... is the taking of a painstaking history".
