People with pacemakers, defibrillators and other cardiovascular implantable electronic devices (CIEDs) are at risk of infection associated with CIED procedures. These infections can result in incremental risk of death in the hospital and after discharge, say researchers at the Mayo Clinic College of Medicine.

Of 200,219 patients who received a CIED, 5,817 were hospitalized for a CIED-related infection over the course of a year. Patients admitted for infection were up to 7.7 times more likely to die than patients without infection.

Researchers think some patients may be more vulnerable than others for several reasons, including being older or having other chronic diseases.
