- Abstract
Background: Cardiac damage is common in patients with acute brain injury; however, little is known regarding cardiac-induced neurological symptoms. In the International Classification of Headache, Third Edition (ICHD-III), cardiac cephalalgia is classified as a headache caused by impaired homeostasis. Methods: This report presents four patients with acute myocardial infarction (AMI) who presented with headache that fulfilled the ICHD-III diagnostic criteria for cardiac cephalalgia. A systematic review of cardiac cephalalgia using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines is also presented. Results: Case 1: A 69-year-old man with a history of percutaneous coronary intervention (PCI) developed sudden severe occipital pain, nausea, and cold sweating. Coronary angiography (CAG) revealed occlusion of the right coronary artery (RCA). Case 2: A 66-year-old woman complained of increasing occipitalgia and chest discomfort while riding a bicycle. CAG demonstrated 99% stenosis of the left anterior descending artery. Case 3: A 54-year-old man presented with faintness, cold sweating, and occipitalgia after eating lunch. CAG detected occlusion of the RCA. Case 4: A 72-year-old man went into shock after complaining of a sudden severe headache and nausea. Vasopressors were initiated and emergency CAG was performed, which detected three-vessel disease. In all four, electrocardiography (ECG) showed ST segment elevation or depression and echocardiography revealed a left ventricular wall motion abnormality. All patients underwent PCI, which resulted in headache resolution after successful coronary reperfusion. A total of 59 cases of cardiac cephalalgia were reviewed, including the four reported here. Although the typical manifestation of cardiac cephalalgia is migraine-like pain on exertion, it may present with thunderclap headache without a trigger or chest symptoms, mimicking subarachnoid hemorrhage. ECG may not always show an abnormality. Headaches resolve after successful coronary reperfusion. Conclusions: Cardiac cephalalgia resulting from AMI can present with or without chest discomfort and even mimic the classic thunderclap headache associated with SAH. It should be recognized as a neurological emergency and treated without delay.
