Abstract
BACKGROUND: Information on the long-term prognosis of patients with infective endocarditis (IE) and valve surgical procedures is scarce, and most analyses are based on registries. This study described outcomes and predictors of mortality in a cohort of consecutive patients with IE with a long-term follow-up. METHODS: A total of 616 of patients with IE seen in an academic institution between 1990 and 2012 were identified and followed. The mean follow-up period was 4.8 ± 5.7 years (median, 2.6 years). RESULTS: Cardiac surgical procedures were performed in 47% of the patients, among whom 77% had surgical procedures in the first 6 months. Six-month and long-term (≥6 month) mortality rates were 15% and 40%, respectively. Older age, male sex, infection in a mechanical valve, Staphylococcus aureus infection, presence of vegetation, stroke, and atrioventricular block were independent predictors of mortality, whereas Streptococcus infection was independently associated with a better prognosis. Valve surgical procedures were independently associated with a decrease in mortality: hazard ratio (HR): 0.38; 95% confidence interval (CI): 0.26 to 0.56 for surgical treatment within 45 days; HR 0.36; 95% CI: 0.22 to 0.61 for surgical treatment between 45 and 180 days; and HR: 0.42; 95% CI: 0.25 to 0.73 for surgical treatment beyond 6 months. Decrease in mortality with valve surgical procedures was found in the two subgroups of patients with definite IE (adjusted HR: 0.36; 95% CI: 0.24 to 0.54; p < 0.0001) and in those with possible IE (HR: 0.40; 95% CI: 0.24 to 0.67; p = 0.0005). CONCLUSIONS: In unselected patients with IE, prognostic factors for long-term mortality were consistent with those identified in previous studies for short-term mortality. These results confirm the apparent benefit associated with valve surgical procedures on long-term prognosis.
