[Infectious endocarditis. Analysis of 20 death cases in Santa Casa de São Paulo].
OBJECTIVE
To analyze the clinical, laboratory and pathological aspects of 20 cases of infectious endocarditis (IE) who died. The authors compared patients with diagnosis before death of IE and those with diagnosis was made after autopsy.


METHODS
Twenty patients who died with IE between April 1982 and November 1991 were studied. We looked for the clinical aspects (fever, cardiac murmurs, anemia, splenomegaly, embolic events and skin manifestation), laboratory aspects (hemocultures), echocardiographic and anatomopathologic features (valvar vegetations events and embolic accidents founded at autopsy). The sample was divided in two sub-groups: A--with clinical diagnosis of IE before and B--without diagnosis before death.


RESULTS
Group A--9 patients aged 8-58 years, 3 men, all them with cardiac murmurs, fever and anemia, 5 with splenomegaly. Hemocultures were done in 7 patients and positive in 1. Echocardiogram with valvar vegetation were found in 4 out of 5 patients (80% positive). At autopsy mitral valve vegetation were present in 7, aortic 3, tricuspid 3. One patient showed the exposure of three valves and two of 2 valves. Embolic events were found in 4. Group B--11 patients most of them older then 50 years (54.5%) (p < 0.05) 5 men, all them presented fever and anemia. Cardiac murmurs in 6 (54%) and none with splenomegaly. In one case hemoculture and echocardiogram, were done and were negative. Anatopathologic study showed compromise of mitral valve in 5, aortic 4, tricuspid 2, pulmonary 1. Two patients had 2 valves compromised. In one case a mural vegetation (right atrium) was found. Embolic events were present in 2 cases.


CONCLUSIONS
In group B a significant number of patients (p < 0.05) were older than 50 years and presented his symptoms as an acute illness. We concluded that older patients with compromised general state and fever with or without embolic events IE must be remember.
