Case Report: Acute inferior myocardial infarction and third-degree atrioventricular block in a patient with hyperthyroidism.

ABSTRACT: We describe the management of a middle-aged male with hyperthyroidism who presented acute inferior myocardial infarction (AIMI) complicated by third-degree atrioventricular (AV) block. The symptoms of AIMI in the patient were atypical. However, his atypical presentation raised clinical suspicion. The electrocardiogram (ECG) was immediately conducted to confirm the patient's AIMI and third-degree AV block. Further coronary angiography revealed that the patient's right coronary artery was completely occluded at the second bend. A stent was placed in the right coronary artery. Following anti-thyroid therapy, the patient's clinical symptoms improved. This case underscores the importance of recognizing atypical presentations in hyperthyroid patients and is followed by a literature review explor
