[Infectious endocarditis in middle-aged and elderly patients].

The analysis is presented of clinical picture, running, therapy and prognosis of infectious endocarditis in 67 patients over 60. They appeared to develop progressive cardiac failure, frequent thromboembolism of the cerebral vessels. The disease is often associated with other age-related disorders, proved difficult for differential diagnosis. Elderly patients show resistance to antibacterial therapy more frequently and have worse prognosis for endocarditis outcome.
