The clinical profiles of infective endocarditis (IE) might have changed in recent years, owing to the advent of transesophageal echocardiography, the introduction of new diagnostic criteria, and the increased frequency of intravenous drug abuse. In this retrospective study, we sought to identify factors affecting the in-hospital outcome of IE patients in a single tertiary referral center in the 1990s (1990-1997). Eighty-eight episodes of IE in 80 consecutive patients admitted from January 1990 through June 1997 were evaluated. Clinical variables that were significantly associated with in- hospital mortality in univariate analyses were entered into a multiple logistic regression model. A total of 22 patients (25%) died. Fatal episodes were significantly more likely than non-fatal episodes to involve older patients (≥ 50 years), use of coumadin, short interval between symptom onset and hospitalization (< 15 days), noncardiac shock, and complications of the heart, central nervous system, and kidneys. White blood cell counts and C- reactive protein concentrations were also significantly higher in fatal than in non-fatal episodes of IE. Multivariate analysis showed that in-hospital mortality was associated with noncardiac shock, neurological complications, cardiac complications, and older age (> 50 years). Compared with previous reports, our findings suggest that the clinical profiles of IE have undergone some changes in the 1990s. The most important prognostic predictors of in- hospital mortality in patients with IE were noncardiac shock and neurologic complications.
