ABSTRACT
PURPOSE: To analyse clinical aspects, diagnosis and treatment of infective endocarditis (IE), in order to guide medical procedures and indicate the surgical treatment. PATIENTS AND METHODS: 83 patients were submitted to clinical treatment of IE between January 1980 and December 1987; clinical aspects, laboratory and pathologic-anatomy findings, the site of infection and the entrance of micro-organism were studied. RESULTS: 37 (44.6%) patients were males. Fever was present in 75 (90.4%) cases, cardiac murmur in 76 (91.5%), splenomegaly in 28 (33.7%) and heart failure (III and IV) in 32 (39.8%) patients. Blood culture was positive in 55.5%; staphylococcus 50% of blood cultures; anemia was present in 66 cases (79.5%) and high serum mucoprotein in 58 (92%); echocardiography was 85.7% positive. The mortality was 39.76%; congestive heart failure was the main cause of death; 78.1% of these ones occurred in the first 15 days of antibiotic-therapy. The mitral valve was the one most impaired and the most frequent entrance of micro-organisms in oropharynx. CONCLUSION: Congestive heart failure, sepsis and systemic embolisms were the main complications that led the patient to death in course of IE, usually before 15 days of antibiotic-therapy. In these cases, we may hypothesize that prompt surgical treatment could have diminished the mortality of IE.
