RESUMO
To assess the effect of our new, more aggressive approach to treating infective endocarditis, we retrospectively reviewed our recent experience with this disease. Between 1983 and 1989, we treated 100 patients with endocarditis, in 94 of whom the diagnosis was confirmed. Fifty-four (57%) of the 94 patients had native valve endocarditis, and the other 40 patients (43%) had prosthetic valve endocarditis. The patients' mean ages were 50 years for native valve disease and 58 years for prosthetic valve disease (p < 0.05). The male-to-female ratio was 4:1. Among the patients with confirmed endocarditis, 87 (93%) had significant underlying risk factors for endocarditis. Upon physical examination of the 94 patients, 16 (17%) were afebrile, 15 (16%) had negative blood cultures, and 26 (28%) had no cardiovascular symptoms or immunologic findings. Echocardiography was of limited value: its sensitivity was 56% for native valve endocarditis and 33% for prosthetic valve endocarditis. The ratio of affected valves was 5 aortic:4 mitral: 1 tricuspid in both forms of the disease. Viridans streptococcus was isolated in 23 (25%) of the confirmed cases, Enterococcus faecalis in 17 (18%), Staphylococcus aureus in 13 (14%), and coagulase-negative staphylococcus in 14 (15%). Gram-negative, anaerobic, and fungal organisms accounted for only 13 (14%) of the confirmed cases.
