BACKGROUND
Brugada syndrome is characterized by specific electrocardiographic changes predisposing individuals to ventricular arrhythmias and sudden cardiac death. Cases of coexisting Brugada syndrome and ischemic stroke are seldom documented, and an underlying pathophysiological link is yet unknown. This article presents a case in which a patient exhibited both Brugada syndrome patterns and an ischemic stroke, prompting a comprehensive literature review to explore the potential association between Brugada syndrome and ischemic stroke.
CASE REPORT
A 49-year-old man, previously healthy, was admitted to the hospital after being discovered unconscious at his workplace. Physical exam showed low oxygen saturation, fever, and abnormal neurological findings. Head computed tomography revealed a significant posterior circulation ischemic stroke. An electrocardiogram revealed Brugada syndrome type II initially, progressing to type III pattern. Despite efforts, the patient’s condition rapidly deteriorated, leading to death within 24 hours. As far as we’re aware, Brugada patterns following a posterior circulation ischemic stroke have only been documented in 1 other instance, in which the patient was also diagnosed with atrial fibrillation.
CONCLUSIONS
Both our literature review and the presented case indicate that Brugada patterns may coexist with and even be associated with ischemic stroke. More extensive research is required to shed light on this potential association. The question of whether Brugada syndrome is a precursor to or a result of ischemic stroke remains unanswered. We propose that patients with ischemic stroke should undergo an evaluation for electrocardiographic signs indicative of Brugada syndrome, particularly if no clear causes, like cardioembolism, are evident.
