We analyzed 270 cases of fungal endocarditis (FE) that occurred over 30 yea
rs. Vascular lines, non-cardiac surgery, immunocompromise and injection dru
g abuse are increasing risk factors. Delayed or mistaken diagnosis (82% of
patients), long duration of symptoms before hospitalization (mean +/- stand
ard deviation, 32 +/- 39 days) and extracardiac manifestations were charact
eristic. From 1988 onwards, 72% of patients were diagnosed preoperatively,
compared with 43% before 1988 (P=.0001). The fungi most commonly isolated w
ere Candida albicans (24% of patients), non-albicans species of Candida (24
%), Apergillus species (24%), and Histoplasma species (6%); recently-emerge
d fungi accounted for 25% of cases. The mortality rate was 72%. Survival ra
tes were better among patients who received combined surgical-antifungal tr
eatment, were infected with Candida, and had univalvular involvement. Impro
vement in the survival rate (from <20% before 1974 to 41% currently) coinci
ded with the introduction of echocardiography and with improved diagnostic
acumen. Fungal endocarditis recurs in 30% of survivors. It is recommended t
hat fungal endocarditis be diagnosed early through heightened diagnostic ac
umen; that patients be treated with combined lipid-based amphotericin B and
early surgery; and that patients be followed up for <greater than or equal
to>4 years while on prophylactic antifungal therapy.
