[Ethanol ingestion following Antabus overdose: acetaldehyde-induced cardiological emergency].

The differential diagnosis of chest pain is challenging, when the clinical presentation appears pathognomonic, yet conventional diagnostic tests fail to reveal the suspected cause. We report the case of a 38-year-old patient who had an acetaldehyde intoxication (antabuse syndrome) in the setting of disulfiram overdose and ethanol ingestion. The patient presented with severe angina pectoris. Coronary artery disease was suspected, because the patient had risk factors and electrocardiographic repolarization changes were present. During the further investigation it became evident that symptoms were solely caused by acetaldehyde intoxication following disulfiram and alcohol ingestion. Toxic levels of acetaldehyde were found in the patient's serum. Coronary artery disease was ruled out by cardiac catheterization.
