The Duke minor criterion "predisposing heart condition" in native valve infective endocarditis - a systematic review.

BACKGROUND The term “predisposition” is used as an indication of antimicrobial prophylaxis to prevent infective endocarditis and as a criterion for diagnosing infective endocarditis according to the modified Duke criteria. The criterion for diagnosing infective endocarditis in native valves is not well defined. OBJECTIVES To identify conditions that increase the risk for infective endocarditis in native valves, for the diagnosis of infective endocarditis according to the modified Duke criteria.

Infective Endocarditis: How Do We Currently Interpret the Duke Minor Criterion "Predisposing Heart Condition" in Native Valves?

Introduction: The term "predisposing heart condition" is used as an indication of antimicrobial prophylaxis to prevent infective endocarditis (IE) and as a criterion for diagnosing IE according to modified Duke criteria. The purpose of this survey was to elaborate clinician's knowledge and opinion on relevant heart conditions as a Duke minor criterion for the diagnosis of IE.

Methods: A questionnaire was created that consisted of two knowledge and two opinion questions on the term predisposing heart condition.

Diastolic stress echocardiography in the young: a study in nonathletic and endurance-trained healthy subjects.

Background: The response of diastolic Doppler indices to exercise is not well defined for young subjects. The aims of this study were to evaluate this in nonathletic and endurance-trained probands and to correlate echocardiographic data with maximal oxygen consumption.

Methods: In this prospective study, Doppler echocardiography was performed at rest and after exercise in 40 nonathletes (NAs) and 20 endurance-trained athletes (ETs) aged < 40 years, matched for age and gender.
