Initial CT Perfusion-Guided Strategy for Suspected NSTEMI

The diagnostic value of CT perfusion (CTP) has been established in patients with stable coronary artery disease, but relevant studies have not yet been conducted in suspected NSTEMI patients. This study aims to explore the diagnostic and therapeutic value of an initial CTP strategy for suspected NSTEMI patients.

Patients enrolled in the Invasive Coronary Angiography group will directly undergo coronary angiography. If necessary, intracoronary imaging (including IVUS and OCT) will be performed.
