The epidemiological profile of infective endocarditis (IE) has changed dramatically over the last few years.1 Once a disease affecting young adults with previously well-identified valve diseasemostly rheumatic diseaseIE is now affecting older patients, a significant proportion of whom has no previously known valve disease and develop IE as the result of healthcare associated procedures.2
A CHANGING EPIDEMIOLOGY
Until the end of the 1970s, rheumatic valvulopathies and congenital cyanotic cardiopathies were the two most frequent predisposing factors for IE. Then, a few years after the effective eradication of rheumatic fever, post-rheumatic valvulopathies gradually disappeared. However, other predisposing factors emerged, such as intravenous drug use, valve prostheses, degenerative valve sclerosis, and invasive procedures at risk for bacteraemia, which resulted in nosocomial and health care-associated endocarditis.3 These changes had at least two consequences: (1) the absence of a reduction in the incidence of IE; and (2) major changes in the microbiological profile of IE.
