title: Headache as a manifestation of myocardial infarction.
abstract: We report a 64-year-old man who complained of headache without chest pain at the onset of acute myocardial infarction (AMI). He had no history of chest pain or headache. Severe headache in this case was the first symptom of AMI. The headache was reproduced during stress test. During the angioplasty procedure, he also complained of headache without vasospastic change in the coronary artery. These findings suggest that the headache which accompanied AMI or myocardial ischemia in this case was due to referred pain rather than a generalized vasospastic disorder.
