Identification of high-risk subgroups in XXXX and the role of echocardiography.

The outcome of @entity884 remains poor. It has an overall mortality of around 30%, rising in high-risk subgroups to 50% and 100%. The prognosis can be improved by identification of high-risk @entity1 and special management. @entity1 with @entity884 are found to be at high risk for @entity204 or serious complications when one or more of the following factors exist: old age (especially > 60 years old), delayed diagnosis, @entity1793 , @entity886 , large @entity340 , @entity712 , @entity149 or coronary artery, prosthetic @entity281 , recurrent events, and failed antibiotic therapy. These factors often coexist and interrelate with one another. Early diagnosis and active treatment are critical for a better clinical outcome. However, @entity884 is difficult to diagnose because of the atypical clinical manifestations and frequent negative results from blood culture. Echocardiography plays an indispensable role in the diagnosis and management of suspected or known @entity884 . By detecting and monitoring certain pathological changes associated with the disease, e.g. vegetation, @entity733 formation, or @entity340 , echocardiography helps to diagnose the disease early, to identify @entity1 at high risk, to monitor the @entity1 , and to optimize the timing and mode of surgical intervention. Serious complications can thus be avoided or cured at an early stage and the prognosis significantly improved.
