STEMI patients post thrombolysis

Hello po! Curious GP here (not yet in training). Recently encountered a case of a STEMI patient na nag-thrombolysis. Yung resident in charge (RIC) put the patient on NPO, so I asked bakit kailangan—sabi niya to prevent GI bleeding. Naghanap ako ng sources online pero wala akong mahanap na solid na evidence supporting this. So legit ba na kailangan talagang NPO ang post-thrombolysis STEMI patients? Or case-to-case basis lang?

The only rationale I got from searching is only if pending CABG or PCI yung patient if nag fail ang thrombolysis.
