Abstract
Purpose
The purpose of this study was to describe left-sided infective endocarditis (LSIE) in persons who inject drugs (PWID) and compare that group to PWID with non-LSIE and to non-PWID with LSIE.
Methods
Retrospective single-center study of adult IE patients from 2011 to 2018.
Results
Of the 333 patients in our cohort, 54 were PWID with LSIE, 75 were PWID with non-LSIE, and 204 were non-PWID with LSIE. When comparing LSIE vs non-LSIE in PWID, the LSIE group was older (median age 35 vs 28.5, p < 0.01), had fewer S. aureus infections (59% vs 92%, p < 0.01), was more likely to have cardiac surgery (31% vs 13%, p < 0.01), and had a higher 10-week mortality (22% vs 5%, p < 0.01). When comparing PWID with LSIE to non-PWID with LSIE, the PWID group were younger (median age 35 vs 46, p < 0.01); had more frequent multi-valve involvement (33% vs 19%, p = 0.04), Staphylococcus aureus infections (54% vs 27%, p < 0.01), and previous IE (24% vs 8%, p < 0.01); and experienced more strokes (54% vs 31%, p < 0.01). Ten-week mortality was similar for LSIE in both PWID and non-PWID (24% vs 20%, p = 0.47).
Conclusions
LSIE in PWID is not uncommon. Compared to non-LSIE in PWID, valve surgery is more common and mortality is higher. For reasons that are unclear, stroke is more frequent in LSIE in PWID than in non-PWID with LSIE but mortality is no different.
