Overview
Cardiac involvement with Giant-cell arteritis or temporal arteritis is rare. Patients with either condition may experience chest pain if they have aortic root involvement or myocardial infarction.
Granulomatous giant-cell arteritis could be present with [temporal arteritis] in 10-15% of patients, or it could manifest on its own. The use of tissue analysis to find granulomatous giant cell coronary arteritis is rare, as are proven cases leading to fatal [myocardial infarction].[1]
Giant cells can be found along the degenerative internal elastic membrane of the arterial wall. The intima thickens to the point it becomes a fibrous cord. Harrison may have also noticed luminal thrombosis in 16 cases of [temporal arteritis], though only one involved the epicardial coronary arteries. Giant-cell arteritis of intramural coronary arteries is also possible. [1]
Giant cell arteritis can lead to vascular inflmmation of the proximal aorta, extracranial head structures, and upper extremities.
Extracranial vascular involvement is clinically detectable in 10-15% of patients with giant cell arteritis. It often presents dramatically as an unsuspected cause ofaortic dissection or ruptured aortic aneurysm in the elderly [2]
CT scans and MRI with T2-weighted images are enough for diagnosis.
