Context Since the first modern clinical description of infective endocarditis
(IE) at the end of the 19th century, the profile of the disease has evolved
continuously, as highlighted in epidemiological studies including a French
survey performed in 1991.
Objective To update information gained from the 1991 study on the epidemiology
of IE in France.
Design and Setting Population-based survey conducted from January through December 1999
in all hospitals in 6 French regions representing 26% of the population (16
Patients Three hundred ninety adult inpatients diagnosed with IE according to
Main Outcome Measures Incidence of IE; proportion of patients with underlying heart disease;
clinical characteristics; causative microorganisms; surgical and mortality
Results The annual age- and sex-standardized incidence was 31 (95% confidence
interval [CI], 28-35) cases per million, not including the region of New Caledonia,
which had 161 (95% CI, 117-216) cases per million. There was no previously
known heart disease in 47% of the cases. The proportion of prosthetic-valve
IE was 16%. Causative microorganisms were: streptococci, 48% (group D streptococci,
25%; oral streptococci, 17%, pyogenic streptococci, 6%); enterococci, 8%; Abiotrophia species, 2%; staphylococci, 29%; and other
or multiple pathogens, 8%. Blood cultures were negative in 9% and no microorganism
was identified in 5% of the cases. Early valve surgery was performed in 49%
of the patients. In-hospital mortality was 16%. Compared with 1991, this study
showed a decreased incidence of IE in patients with previously known underlying
heart disease (20.6 cases per million vs 15.1 cases per million; P<.001); a smaller incidence of oral streptococcal IE (7.8 cases
per million vs 5.1 cases per million; P<.001),
compensated by a larger proportion of IE due to group D streptococci (5.3
cases per million vs 6.2 cases per million; P = .67)
and staphylococci (4.9 cases per million vs 5.7 cases per million; P = .97); an increased rate of early valve surgery (31.2% vs 49.7%; P<.001); and a decreased in-hospital mortality rate
(21.6% vs 16.6%; P = .08).
Conclusion Although the incidence of IE has not changed, important changes in disease
characteristics, treatment, and outcomes were noted.
