AI Article Synopsis
- Giant cell arteritis (GCA) is a systemic vasculitis that primarily affects the extra cranial branches of the carotid arteries but can also impact other blood vessels, potentially leading to serious conditions like thoracic aorta aneurysm and myocardial infarction.
- A case study highlighted a 70-year-old woman with GCA who presented symptoms resembling acute myocardial infarction, including chest pain and heart dysfunction, but normal cardiac troponin levels and angiography findings.
- Her symptoms improved significantly after receiving steroid treatment, emphasizing that cardiac issues are uncommon in the initial presentation of GCA.
Article Abstract
Giant cell arteritis (GCA), also known as granulomatous arteritis is a systemic vasculitis mainly affecting extra cranial branches of carotid arteries. It can rarely affect other vascular beds causing thoracic aorta aneurysm, dissection and rarely cause myocardial infarction through coronary arteritis. It can cause considerable diagnostic dilemma due to varied clinical presentations. The authors report an illustrative case of a 70-year-old woman with GCA who developed symptoms suggestive of acute myocardial infarction with chest pain, localised ST-T changes and echocardiographic left ventricular dysfunction. However, cardiac troponin T biomarkers and coronary angiography were normal. Her symptoms subsided with steroid treatment. Cardiac symptoms at first presentation of GCA are unusual.
