[Cardiac arrest secondary to thyroid storm].

Area of Science:

• Endocrinology
• Internal Medicine
• Critical Care Medicine

Background:

• Thyroid storm is a rare, life-threatening exacerbation of thyrotoxicosis.
• It can be triggered by various factors including Graves' disease, toxic goiter, amiodarone, or trauma.

Observation:

• Clinical manifestations are diverse, with cardiovascular complications being the most critical, potentially leading to cardio-respiratory arrest.
• Diagnosis is often challenging, leading to delayed management.

Findings:

• Treatment involves symptomatic management, antithyroid drugs, beta-blockers, and glucocorticoids to inhibit T4 to T3 conversion.
• Thyroid surgery, radioactive iodine therapy, and extracorporeal membrane oxygenation (ECMO) are also therapeutic options.

Implications:

• Prompt recognition of thyroid storm in hyperthyroid patients is essential.
• Multifaceted treatment strategies are required to improve patient outcomes in this critical condition.
