title: [Infective endocarditis. 5-years experience in a third-level reference center in Yucatan, Mexico].
abstract: BACKGROUND
  Infective endocarditis is a disease with high morbidity and mortality. The clinical characteristics differ among populations. Therefore it is important to know the characteristics of the disease in our region.
  
  
  METHODS
  This is an observational study that included all patients diagnosed with infective endocarditis from 1 January 2009 until 31 December 2014. The data are showed as frequencies and percentages altogether with medians with interquartile range.
  
  
  RESULTS
  10 cases were included. The median age was 34 years (IQR 26-41). Several risk factors were identified and included: previous valvular heart disease, patients with chronic kidney disease who have had a vascular access and previous history of immunological disease. The native mitral valve was the most affected. The size of vegetations had a median length of 14 mm (IQR 9.3-16). Streptococcus alpha hemolytic was the most common organism. In-hospital mortality rate was 10 %.
  
  
  CONCLUSIONS
  The behavior of the disease is similar to other national series. We identify risk factors that could be related to the type of morbidities in the region.
