Thyrotoxicosis associated atrial fibrillation occurs in 9 to 22% of hyperthyroidism patients; its prevalence increases after the age 60 years. Atrial fibrillation is known to be major independent risk factor for a thromboembolic stroke. The characterization of patient subgroups with atrial fibrillation, with high or low rate risk factor of a stroke, would help clinicians decide the benefit or harm to patient of long term anticoagulation therapy. Thyrotoxicosis, old age, hypertension, diabetes, heart failure, history of stroke and thromboembolism are all high risk factors for a stroke in atrial fibrillation patients. Thus, anticoagulation therapy is recommended for stroke prevention in those groups with atrial fibrillation and thyrotoxicosis. Herein is reported a case of acute cerebral infarction, with thyrotoxic atrial fibrillation and congestive heart failure, in a young woman
Key Words: Thyrotoxicosis, Atrial fibrillation, Thromboembolism
