Dual Antiplatelet Therapy (DAPT)

The following question refers to Section 5.2.1 of the 2025 ACS Guidelines.

A 63-year-old woman presented to the emergency room for chest pain. She described having exertional chest pain for the past two months and had an episode of severe pain after dinner 3 days ago. She went to bed and slept it off. She told her children today at a family gathering, and was immediately brought to the ED by her daughter. She has a history of hypertension and hyperlipidemia. She was asymptomatic and normotensive in the ED. Labs show a down-trending troponin and an elevated NT-proBNP but are otherwise unremarkable. Her ECG showed Q waves with ST elevation in V2-V4. She was treated with aspirin and heparin drip, and taken to the cath lab. Coronary angiogram showed complete proximal LAD occlusion with right-to-left collaterals, without significant residual disease elsewhere. She remains asymptomatic and is stable, both hemodynamically and electrically.

What is the next best step with regard to reperfusion and anti-thrombotic management?
