Ischemic Stroke Unveiling Takayasu Arteritis Complicated by Coronary Arteritis: A Case Study

Context: We present the case of a 38-year-old woman admitted for ischemic stroke. Etiological evaluation revealed halo signs on transesophageal echocardiography (TEE), suggestive of Takayasu arteritis. Case Presentation: During hospitalization, the patient developed chest pain, elevated troponin levels (300 ng/L), left ventricular hypokinesia on echocardiography, and T-wave inversions on electrocardiogram (ECG), indicating coronary arteritis. High-dose corticosteroid therapy led to rapid improvement in inflammatory markers. The diagnosis of Takayasu arteritis was confirmed based on the American College of Rheumatology (ACR) criteria. This case highlights the variable clinical presentation of Takayasu arteritis, including coronary involvement, and underscores the effectiveness of corticosteroid therapy in controlling inflammation. Conclusion: Takayasu arteritis, though rare, can manifest with ischemic stroke and coronary arteritis. Prompt recognition and corticosteroid treatment are essential in managing this potentially life-threatening condition.
