Answer

Endocarditis may be associated with new therapeutic modalities involving intravascular devices such as central or peripheral intravenous catheters, rhythm control devices such as pacemakers and defibrillators, hemodialysis shunts and catheters, and chemotherapeutic and hyperalimentation lines. [20, 21] These patients tend to have significant comorbidities, more advanced age, and predominant infection with S aureus. The mortality rate is high in this group.

The organisms that cause NIE/HCIE obviously are related to the type of underlying bacteremia. The gram-positive cocci (ie, S aureus, CoNS, enterococci, nonenterococcal streptococci) are the most common pathogens.
