RISK FACTORS AND CLINICAL FEATURES OF INFECTIVE ENDOCARDITIS IN PATIENTS WITH NO UNDERLYING HEART DISEASE

Abstract
Infective endocarditis (IE) pathogenesis has changed in the last decades and there is an increasing number of patients without predisposing heart condition. The aim of this study is to asses the clinical features of theses nondrug addict patients affected with IE without underlying heart disease and to identify the potential risk factors. From 154 cases o IE diagnosed at our centres, 61 (40%) occurred in patients without underlying heart disease. A presumed portal of entry was identified in the majority (30 cases). The most frequent were digestive (7 cases), haemodialysis (6 cases) and central venous catheters (5 cases). Right heart valves were more often affected (31% vs. 10%, p < 0.05). The distribution of the causative microorganism showed a higher proportion of Stahylococcus (52% vs. 26%, p < 0.01). Despite similar in-hospital complication rate and a similar need of surgery during the active phase, their prognosis is better than in those cases with underlying heart disease.
