The previously totally occluded by a thrombus (manifesting as stemi). systemic inflammation (described earlier) is thought to play a role. stable plaque ruptures, releasing substances into the vessel. This area may be partially occluded by a thrombus (manifesting as ua or nstemi) or. What causes a coronary plaque to suddenly become unstable is not well understood, but. Patients with suspected acs require immediate hospitalization. Partial occlusion of coronary artery: ua or nstemi. Non occulusive thrombus, non specific ecg, normal cardiac enzymes.
