In high-risk NSTE-ACS, dynamic T-wave inversion is typically accompanied by which symptom?

• A. Dizziness
• B. Pain
• C. Fever
• D. Shortness of breath

Answer: (B)

Dynamic T-wave inversion on ECG in high-risk NSTE-ACS points to ongoing myocardial ischemia. The symptom that most commonly accompanies ischemia is chest pain or angina, which arises from the heart muscle not getting enough oxygen. While dizziness, shortness of breath, or fever can occur in some patients with ACS, they are not the typical presenting symptom tied to ischemic ECG changes. Therefore, chest pain best matches the scenario described.
