ABSTRACT
Introduction: BRASH syndrome (bradycardia, renal failure, atrioventricular block, shock, and hyperkalemia) is an emerging entity in emergency medicine. Its pathophysiology may mask other critical conditions such as ST-elevation myocardial infarction (STEMI).Objective: to describe the clinical presentation and progression of a patient with BRASH syndrome associated with an evolved ST‑segment elevation myocardial infarction (STEMI), in order to analyze the diagnostic and therapeutic challenges encountered during the multidisciplinary management of the case.
Methods: a descriptive clinical case report was conducted. Clinical information was obtained through a retrospective review of the patient’s medical record and laboratory studies at Hospital Regional de Sogamoso E.S.E. A literature search was carried out in databases such as PubMed. Because the patient had died at the time of manuscript preparation, it was not possible to obtain informed consent for publication. All clinical information was thoroughly de‑identified to ensure that the patient cannot be reasonably recognized, in accordance with privacy and confidentiality standards for case reports.
Case reports are not considered human subjects research and therefore do not require Institutional Review Board approval.
Results: the patient received comprehensive management for hyperkalemia and bradycardia, achieving transient recovery of sinus rhythm. However, persistent ST-segment elevation confirmed an evolved STEMI. Despite pharmacological therapy and advanced support, she developed progressive hemodynamic instability and died from refractory cardiogenic shock.
Conclusion: BRASH syndrome may delay the diagnosis of STEMI by altering clinical presentation and electrocardiographic findings. Early recognition and comprehensive management are crucial to improve outcomes in emergency settings.
