x402 APIFailing, checked 3 h ago

Park 2016 ICE Table 5 simplified 6-month IE mortality score: constant 4, age bands (<=45: 0; 46-60: 2; 61-70: 3; >70: 4), and caller-assigned flags (dialysis +3, nosocomial +2, prosthetic +1, symptoms >1 month -1, S. aureus +1, viridans -2, aortic/mitral vegetation +1 each, NYHA 3-4 +3, stroke +2, paravalvular +2, persistent bacteremia +2, surgery -2). Returns score, quadratic mortality percent, and score >= 8. Not a diagnosis. magent does not examine the patient or decide surgery.
