There were 24, 35, 174 and 67 patients in the group A, B, C and D, respectively.Group A along with group D were characterized by the highest rate of prior medical encounters in the past year. Group A had the highest rate of nonfunctional\/redundant leads.Group A along with group D were characterized by the highest rate of prior medical encounters in the past year and the largest number of nonfunctional\/redundant leads. The most numerous group C compared with other groups had the best cardiac function measured with NYHA functional class and LVEF. The smallest mean number of leads in one patient was in group D, which consisted of patients requiring device upgrades. The largest mean number of prior device\-related procedures per patient was observed in groups with infectious indications.Patients referred from other centers had significantly more often class I indications compared with class IIb indications.The risk factors predisposing to development of infective endocarditis in the assessed populations were\: higher NYHA heart failure class, presence of nonfunctional\/redundant leads and frequent prior medical encounters with the exclusion of dialysis.Patients with localized pocket infection in comparison with groups with noninfe"]
