Myocardial infarction presenting solely as an acute, severe headache is underdiagnosed in elderly patients. In patients over 80 years of age, myocardial infarction presents more commonly with atypical symptoms than with chest pain. The authors describe two patients who presented with headache as the only symptom of an acute myocardial infarction. The authors recommend that acute myocardial infarction be considered in the differential diagnosis of acute, severe headache in elderly patients.
