Insights
Temporal arteritis, a condition often missed, can present with acute myocardial infarction in patients over 50. Early diagnosis via biopsy and prompt corticosteroid treatment are crucial for favorable outcomes.
Area of Science:
- Cardiovascular Medicine
- Rheumatology
- Internal Medicine
Context:
- A 60-year-old male presented with acute myocardial infarction.
- Patient history included headaches and temporal artery abnormalities.
- Inflammatory markers and coronary angiography suggested an underlying condition.
Purpose:
- To report a case of acute myocardial infarction secondary to temporal arteritis.
- To highlight the importance of considering temporal arteritis in older patients with arterial disease and inflammation.
- To emphasize the need for prompt corticosteroid therapy.
Summary:
- Diagnosis of temporal arteritis was confirmed by temporal artery biopsy.
- Corticosteroid therapy resulted in a satisfactory outcome at three months.
- Arterial disease in patients with temporal arteritis should be viewed as a manifestation of the condition.
Impact:
- Suggests systematic screening for temporal arteritis in patients over 50 with inflammatory syndrome and new arterial disease.
- Recommends intensifying corticosteroid therapy for any arterial disease occurring during treated temporal arteritis.
Abstract:
The authors report the case of a 60-year-old man admitted for uncomplicated acute myocardial infarction. The history of persistent fronto-occipital headaches and palpation of bilateral tortuous temporal arteries with a decreased pulse suggested the diagnosis of temporal arteritis, particularly in the presence of marked laboratory signs of inflammation and the coronary angiograph findings. The diagnosis was confirmed by temporal artery biopsy. Treatment consisted of corticosteroid therapy, with a satisfactory outcome at three months. The diagnosis of temporal arteritis should be systematically suggested in patients over the age of 50 years, presenting with a marked inflammatory syndrome and recent-onset arterial disease. Similarly, any form of arterial disease occurring during treated temporal arteritis should initially be considered to be a secondary site of the arteritis, requiring intensification of corticosteroid therapy.
