Endocarditis at a large community hospital with on-site cardiac surgery

Objective: Infective endocarditis (IE) is still a serious disease. The currently published EURO-ENDO registry showed a rate of surgery of 51.2% and a lower mortality in operated IE patients. We hypothesized differences between our data and the registry.Methods: Retrospective single centre registry on the hospital course of patients with IE.Results: In four years, 171 IE patients were treated at our hospital. Mean age of patients was 66.5 +/- 13. 8 years and 62.6% of patients were transferred from other hospitals. There were 85 (49.7%) patients with native valve IE (NVE), 53 (31%) with prosthetic valve IE (PVE) and 33 (19.3%) with either intra-cardiac device related IE (n = 29) or IE associated with central access lines (n = 4) (DRE). A total of 81.3% (n = 139) of patients were sent to cardiac surgery. Using a logistic regression model to analyse predictors of conservative instead of surgical therapy the only independent variables were: presence of large vegetation or abscesses (OR: 0.36, 95%CI 0.15-0.83; p = 0.016) and age (for each ten years) (OR: 1.61, 95%CI 1.11-2.32, p = 0.01). Hospital mortality was 21.6% (n = 37/171), with no difference (p = 0.97) between those who were operated (21.6%, n = 30/139) and those treated conservatively (21.9%, n = 7/32). Comparing those treated conservatively without an indication for surgery with those with an indication, mortality was 9.5% versus 45.5%, p = 0.02.Conclusions: In this registry from a hospital with on-site cardiac surgery more than half of patients were referred. The rate of patients treated surgically was 81.3%. Hospital mortality was 21.6%, with no difference between operated and conservatively treated patients. (C) 2021 Published by Elsevier B.V.
