Prevalence of rheumatic heart disease in a public school of Belo Horizonte.
[acute rheumatic fever]
Previous
studies
indicate
that
compared
with
physical
examination
,
Doppler
echocardiography
identifies
a
larger
number
of
cases
of
rheumatic
heart
disease
in
apparently
healthy
individuals
.
To
determine
the
prevalence
of
rheumatic
heart
disease
among
students
in
a
public
school
of
Belo
Horizonte
by
clinical
evaluation
and
Doppler
echocardiography
.
This
was
a
cross-sectional
study
conducted
with
267
randomly
selected
school
students
aged
between
6
and
16
years
.
students
underwent
anamnesis
and
physical
examination
with
the
purpose
of
establishing
criteria
for
the
diagnosis
of
rheumatic
fever
.
They
were
all
subjected
to
Doppler
echocardiography
using
a
portable
machine
.
Those
who
exhibited
nonphysiological
mitral
regurgitation
(
MR
)
and
/
or
aortic
regurgitation
(
AR
)
were
referred
to
the
Doppler
echocardiography
laboratory
of
the
Hospital
das
ClÃnicas
of
the
Universidade
Federal
of
Minas
Gerais
(
HC-UFMG
)
to
undergo
a
second
Doppler
echocardiography
examination
.
According
to
the
findings
,
the
cases
of
rheumatic
heart
disease
were
classified
as
definitive
,
probable
,
or
possible
.
Of
the
267
students
,
1
(
0
.
37
%
)
had
a
clinical
history
compatible
with
the
diagnosis
of
acute
rheumatic
fever
(
ARF
)
and
portable
Doppler
echocardiography
indicated
nonphysiological
MR
and
/
or
AR
in
25
(
9
.
4
%
)
.
Of
these
,
16
(
6
%
)
underwent
Doppler
echocardiography
at
HC-UFMG
.
The
results
showed
definitive
rheumatic
heart
disease
in
1
student
,
probable
rheumatic
heart
disease
in
3
students
,
and
possible
rheumatic
heart
disease
in
1
student
.
In
the
population
under
study
,
the
prevalence
of
cases
compatible
with
rheumatic
involvement
was
5
times
higher
on
Doppler
echocardiography
(
