THE ''X.SYNDROME''
"X-Syndrome" has
an
unknown
cause.
The
present
view
is
a difficulty
in
transfening
the
oxygen
in red blood
cells to the heart
muscles(myocardium).
The
symptoms
are very similar
to
myocardial infarct (lack of
blood).
The
syndrome
can
mimic
coronary
heart
disease
but
there is usually
no
high
blood pressure, diabetes, high choles-
terol
nor
family history
of
coronary heart
disease.
Chest pain
may be very
severe but there
is
no
obvious
disturbance
ol
cardiac
function.
The
prognosis
is
good and even
upon
longterm
follow
up, myocardial infarct
does not
occur.
Treatment is usually
by beta-blockers, which can etlectively
control the accompanying autonomic
nervous system
symptoms.
ln many
patients, the disease would
regress
after
menopause.
