Acute myocardial infarction in the absence of obstructive coronary artery disease (MINOCA) represents a diagnostic challenge in clinical practice. Documentation of an ischemic substrate is necessary for its diagnostic approach, with a treatment that must be specific according to the identified etiology. A group of these patients presents ischemia secondary to an alteration in the oxygen supply/demand ratio. We present the case of a female adult patient, with severe hyperthyroidism and thyrotoxicosis, who develops an acute coronary syndrome, with elevated troponin T and normal coronary arteries on coronariography. Treatment was aimed at treating the triggering cause, initially pharmacologically and later surgically, with a total resolution of the condition, symptomatic improvement in the patient, and a decrease in cardiac biomarkers.

 Arrhythmic storm is characterized by the occurrence of three or more distinct episodes of ventricular tachycardia or ventricular fibrillation within a 24-hour period, posing a signifcant risk for cardiovascular complications and resulting in high morbidity and mortality. The objective of this review article is to provide recommendations for the management and pharmacological treatment with the greatest impact on patients with arrhythmic storm, based on the latest global literature. A literature search was conducted in the PubMed and Scielo databases,focusing on updated and relevant articles in English or Spanish published within the last 10 years, detailing the clinical signifcance of arrhythmic storm, its implications, and therapeutic approaches. This condition is multifactorial, highlighting the importance of timely diagnosis to control the triggering cause. Given its high recurrence...
