A case of a young patient, heavy drinker, who suffered an acute myocardial infarction (AMI), and whose cinecoronariography, early post unsuccessful intravenous thrombolysis, showed the presence of thrombi in multiple arteries is reported. A second cinecoronariography performed on the 7th day post AMI revealed normal coronary arteries. There were no plasmatic lipid or coagulation abnormalities, nor other risk factors for coronary artery disease. We speculate about the role of the heavy alcohol ingestion in this particular case.
