Pathophysiology
Clinical meaning
Infective endocarditis vegetations consist of fibrin, platelets, and trapped bacteria forming on valve endothelium. Vegetation size >10mm, mobility, and mitral valve location increase embolic risk. S. aureus produces biofilm and tissue-destructive enzymes, causing rapid valve destruction, abscess formation, and high embolic rates. Connect Infective Endocarditis Advanced 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.
