Sudden Cardiac Death in a Young Man with Migraine-associated Arrhythmia
Abstract
A 31-year-old man with migraine-induced syncope and bradycardia with subsequent pacemaker implantation died unexpectedly. Clinically unsuspected cardiac anomalies were found at autopsy including myocardial bridging of the left anterior descending artery and shelf-like coronary artery ostia. Nortriptyline was identified by toxicologic analysis. A review of the autopsy findings, the historical information, and the effects of the possible arrhythmogenic circumstances is undertaken and the potential contributions to the death are discussed. Cardiac arrhythmias have been documented during migraines. Coronary artery bridging has been known to lead to ischemia and infarction, ventricular tachycardia, and sudden death; however, these are very rare sequelae. Congenital coronary artery anomalies have been linked to sudden cardiac death, but only rarely cause death in people younger than 31 years. Migraines and the autopsy findings described have been associated with cardiac arrhythmia and sudden death. Altogether, they led to the unexpected death of this young man.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
