2 major criteria Or
1 major+3 minor
or 5 minor
Major: positive blood culture, evidence of endocardial involvement by echo
Minor: 1) predisposing cardiac condition or history of IVDU, 2) fever > 38, 3) vascular manifestations, 4) immunologic manifestations, 5) microbiological evidence is not including the major criteria
