Pathophysiology
Clinical meaning
Acute coronary syndrome encompasses unstable angina, NSTEMI, and STEMI. Vulnerable atherosclerotic plaque ruptures, exposing the thrombogenic lipid core to circulating blood. Platelet adhesion and activation trigger the coagulation cascade, forming a thrombus that partially (NSTEMI) or completely (STEMI) occludes the coronary artery. Connect ACS Management to bedside cues you will reassess first: vitals trends, work of breathing, perfusion, mentation, and pain or ischemic equivalents when relevant. Boards reward recognizing when subtle instability outweighs reassurance, then selecting nursing actions that protect airway, circulation, and neurologic status before routine tasks.
