RT Journal Article SR Electronic T1 Acute coronary syndromes can be a headache JF Emergency Medicine Journal JO Emerg Med J FD BMJ Publishing Group Ltd and the British Association for Accident & Emergency Medicine SP 71 OP 73 DO 10.1136/emj.2009.082271 VO 28 IS 1 A1 C Costopoulos YR 2011 UL http://emj.bmj.com/content/28/1/71.abstract AB Ischaemic heart disease is a common cause of morbidity and mortality worldwide. Patients typically present with chest pain and breathlessness either on exertion or at rest. Cardiac ischaemia can also lead to headache, although this is very rarely its only manifestation. Headache is mostly associated with migraine, cluster and tension headache disorders. More sinister causes include subarachnoid haemorrhage, temporal arteritis, meningitis, venous sinus thrombosis as well as vertebral and carotid artery dissection. A case of headache is presented where the underlying cause was cardiac ischaemia, itself the result of triple vessel coronary artery disease. This, also referred to as cardiac cephalgia, should be suspected in the older patient with risk factors for atherosclerotic disease presenting with recent-onset headache. Diagnosis of this requires high clinical suspicion and is essential for correct patient management.
