title: [Trends for the etiology of infective endocarditis at our hospital these 5 years].
abstract: The aim of this study is to evaluate characteristics of infective endocarditis for 5 years at Kanazawa University Hospital. Retrospectively, we investigated 39 patients diagnosed as infective endocarditis at our hospital from 2006 to 2010 based on blood culture and/or rejected cardiac specimens. Of 39 patients with infective endocarditis, 27 were male and 12 were female. Mean age was 55.4 years and 69% patients were older than 50 years. The frequent underlying presumed diseases were cardiac diseases. Vegetation was mainly observed at mitral valve and aortic valve. Streptococcus species [14 cases (36%)] and Staphylococcus species [12 cases (31%)] were common pathogens. In Streptococcus species, the critical cause was mostly presumed to be associated with dental procedure and oral cavity. In Staphylococcus species, intravascular device and soft tissue infection were also frequently presumed. Frequency of chronic kidney disease and infection around valve were higher in Staphylococcus species than those observed in Streptococcus species [12 cases (100%) vs. 7 cases (50%); p < 0.05, 6 cases (50%) vs. 1 case (7%); p < 0.05]. Our results suggested that the etiology of patients with Staphylococcus species infection increased in number among patients suffering from infective endocarditis at our hospital.
