Wu Z, et al. - Researchers here sought to report the clinical features and prognosis of infective endocarditis (IE) in the elderly from a tertiary teaching hospital in east China. In this cohort study, they included 405 patients with definite IE and divided them into three groups: 205 patients under 50 years old, 141 patients between 50 and 64 years old and 59 patients over 65 years old. Relative to younger patients, older patients with IE presented with more comorbidities, bad oral hygiene, more nosocomial origin, and a more severe prognosis. Micro-organisms most frequently isolated in this group were Streptococci. In old patients, surgery was underused and better prognosis was observed in those with surgical treatment.
