Antibiotics alone or surgery? study tracks which endocarditis patients fare better
NCT ID NCT07825272
First seen Sep 17, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
Infective endocarditis is an infection of the heart's inner lining or valves. About half of patients need surgery during their hospital stay, while others receive antibiotics alone. Researchers are following 1,046 adults with confirmed endocarditis for up to 24 months to compare major health events, such as death, recurrent infection, hospitalization, and heart failure, between the two groups. The goal is to learn which patients do well without surgery and how best to monitor them long term.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If the study identifies which patients fare better with antibiotics alone, it could shape follow-up guidelines and spare some people unnecessary surgery.
- What could go wrong
- This is an observational study, so it can show patterns but cannot prove that one treatment causes better outcomes. Patients who have surgery tend to be sicker, which can make comparisons misleading.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The study will enroll approximately 1,046 patients with definite infective endocarditis across participating centers, including both retrospective and prospective cohorts. The retrospective cohort will include patients diagnosed from 2021 onward with available clinical and follow-up data. The prospective cohort will consist of consecutive patients enrolled during the study period according to routine clinical practice. Both cohorts will include patients managed surgically and patients managed with medical therapy alone. All patients will be treated according to standard clinical practice, with no additional interventions required for study participation.
