What are the modified Duke criteria for infective endocarditis?
Understand the Problem
The question involves understanding the modified Duke criteria for diagnosing infective endocarditis, specifically focusing on major and minor criteria as well as associated mnemonics.
Answer
The modified Duke criteria include specific major and minor criteria for diagnosing infective endocarditis. A definitive diagnosis requires two major criteria, or one major and three minor criteria, or five minor criteria. A possible diagnosis requires one major and one minor criterion, or three minor criteria.
The modified Duke criteria for infective endocarditis are divided into major and minor criteria. The major criteria include positive blood cultures (≥2 times 12 hours apart) and echocardiographic evidence of endocardial involvement. The minor criteria include fever (>38 °C), immunological phenomena, microbiological evidence not meeting a major criterion, embolic phenomenon, and risk factors (congenital heart condition or IV drug use). A definitive diagnosis requires two major criteria, or one major and three minor criteria, or five minor criteria. A possible diagnosis requires one major and one minor criterion, or three minor criteria.
