[Cardiac insufficiency in infectious endocarditis].
The aim of this study of 101 cases of infective endocarditis was to determine the factors predisposing to cardiac failure, the prognostic factors of this complication and the therapeutic implications. A significant (p less than 0.05) Chi square test was the statistical reference. Fifty-two per cent of patients developed cardiac failure which was biventricular in 48 p. 100 of cases and the presenting symptom in 64 p. 100. The mean age of the patients with cardiac failure was 56.6 years with a clear male predominance. In 48 p. 100 of cases, cardiac failure complicated a pre-existing cardiac lesion which was usually acquired (84 p. 100). The commonest condition was valvular insufficiency of the aortic and mitral valves (70 p. 100 of cases with cardiac failure). Severe cardiac failure was observed more frequently and earlier in aortic than in mitral regurgitation. The commonest infecting organism was the streptococcus (53 p. 100 of cases with cardiac failure) and the most frequent presumed portal of entry was dental (25 p. 100). Arrhythmias were observed in 51 p. 100 of patients in cardiac failure, the commonest being atrial fibrillation (34 p. 100) complicating mitral valve disease in 56 p. 100 of cases; 17 p. 100 of arrhythmias were ventricular. Conduction defects were observed in 26 p. 100 of cases with cardiac failure, 55 p. 100 of which had aortic valve disease. Valvular vegetations were demonstrated by echocardiography in 43 p. 100 of cases with cardiac failure. Valve replacement had to be performed for resistant cardiac failure in 13 p. 100 of cases.(ABSTRACT TRUNCATED AT 250 WORDS)
