Infectious Endocarditis: A year of changing patterns
Keywords:
Infectious endocarditis, changing patterns, epidemiologyAbstract
The authors made a retrospective analysis of 15 case reports of
infectious endocarditis diagnosed in 2004, which represented
a significant increase in comparison to the four previous years.
The objective was to look for epidemiological and clinical characteristics that could justify this increase. In 2004 the mean
age increased about a decade and the predisposing factors were
inverted. Valvular heart disease has assumed relevance and there
was a decrease of about 50% in drug abuse and HIV infection
among patients with endocarditis. The sub-acute clinical presentation almost doubled and fever was the only manifestation that
remained unchanged during these years. The pathogens isolated
in blood cultures were different with an important reduction in
MRSA. There was an increase in embolic cerebral complications
and valvular complications with urgent need for surgery but significantly less mortality.
Conclusion: in 2004 there was a signifi cant increase in infectious endocarditis with a change in the epidemiological, clinical
and microbiological patterns. A causal factor that could explain all these changes was not identified.
