Echocardiography Versus no Echocardiography in S. Aureus Bacteraemia and VIRSTA Score < 3
Recruiting now · Not applicable
Conditions studied: Staphylococcus Aureus, Bacteremia, Infective Endocarditis
In brief
Staphylococcus aureus is the most frequent cause of both healthcare-associated and community-acquired bloodstream infections worldwide. Infective endocarditis (IE) has been detected in 5-17% of cases and is a determinant of poor prognosis. The investigators developed a score (the VIRSTA score) based on patients' characteristics to rule out IE with high confidence (negative predictive value (NPV) above 99%) in patients with SAB. This score, with a cut-off of 3 has been externally validated by two international studies which have also established its high NPV. The 2023 European society of cardiology (ESC) guidelines state that echocardiography should be considered in all patients with Staphylococcus aureus bacteremia (SAB) using risk scores (including VIRSTA score) to guide the use or not of echocardiography. While recommended, the investigators think that VIRSTA score must be evaluated in terms of patients' outcome.
