Evolution of electrocardiographic manifestations mimicking acute coronary syndrome secondary to hypoparathyroidism: a case report

Vollständiger Abstract

Worum geht es in dieser Arbeit?

Objective To promptly identify electrocardiographic (ECG) manifestations, including deep T-wave inversions and QT-interval prolongation, secondary to hypoparathyroidism and to improve its diagnostic accuracy and therapeutic management. Methods We conducted a comprehensive analysis of the integrated treatment for a patient presenting with chest pain and evolving ECG changes secondary to hypoparathyroidism, supplemented by a review of the relevant literature. Results In this case, a patient diagnosed with hypoparathyroidism presented with chest pain and dynamic ECG alterations. Following a confirmed diagnosis, treatment with calcium supplementation successfully alleviated the patient's chest pain and resulted in the complete normalization of the previously abnormal ECG findings. Conclusion Clinical presentations mimicking angina pectoris, accompanied by secondary ECG changes such as deep T-wave inversions and QT-interval prolongation, are relatively uncommon in patients with hypoparathyroidism. A thorough evaluation combining clinical presentation, characteristic signs, and laboratory investigations can significantly reduce the rate of misdiagnosis.
