Amiodarone and Myocardial Infarction Risk in Thyroid Storm

Introduction to Amiodarone Risks

Amiodarone should be avoided in patients with thyroid storm due to its potential to exacerbate thyrotoxicosis and increase cardiovascular complications, including the risk of myocardial infarction, as recommended by the American College of Cardiology 1

Cardiovascular manifestations of thyroid storm include tachyarrhythmias, as noted by the American College of Cardiology 2
Hypotension is a cardiovascular manifestation of thyroid storm, according to the American College of Cardiology 3
Heart failure exacerbation is a potential consequence of thyroid storm, as stated by the American College of Cardiology 4

Beta-blockers are the first-line treatment for rate control in patients with thyroid storm and arrhythmias, as recommended by the American College of Cardiology 4 and the European Society of Cardiology 6
Non-dihydropyridine calcium channel antagonists are recommended alternatives when beta-blockers are contraindicated, according to the European Society of Cardiology 6

For patients with thyroid storm requiring antiarrhythmic therapy, beta-blockers should be first-line treatment, as recommended by the American College of Cardiology 4 and the European Society of Cardiology 6
Amiodarone should be discontinued if it was previously prescribed for patients with thyroid storm, as stated by the American College of Cardiology 5 and 1
Direct current cardioversion is recommended for hemodynamically unstable patients with life-threatening ventricular arrhythmias, according to the American College of Cardiology 4
Alternative antiarrhythmic agents should be considered for patients with life-threatening ventricular arrhythmias, as noted by the American College of Cardiology 1
