title: Acute non-ST-elevation myocardial infarction presented as occipital headache with impaired level of consciousness--a case report.
abstract: Headache represents a rare manifestation of myocardial ischemic pain. It is believed that this clinical symptom results from convergence of heart autonomic fibers with somatic inputs originating from the head. The authors describe for the first time the case of a 73-year-old woman who experienced an acute non-ST-elevation myocardial infarction that manifested solely with intense occipital headache associated with vomiting and impaired level of consciousness. This unusual case highlights that the exclusion of an intracranial event in patients presenting with a severe headache and ischemic-like electrocardiographic abnormalities should raise the possibility of an acute coronary event, especially in elderly individuals with cardiovascular risk factors. Furthermore, the occurrence of episodic short-lasting headaches during exertion should direct diagnostic work-up toward ischemic heart disease.
