Angina pectoris
is
a
common symptom
of
coronary
heart
disease.
lt
is
caused
by
insufficient
blood
supply
of
the coronary
arteries,
and
leads
to
a
sudden
and
temporary
myocardial
ischemia.
The
clinical
appearances
show intermittent
oppression
of
chest
and
retro-sternual
pain, which sometimes
radiates
to
the
precordial region and the left upper limb.
The duration
of
the
attack
is
rather short,
usually
1
to
5
minutes,
and
always
less
than
15
minutes.
lt
happens
more
common
in
middle aged
and
old
people
with
various
clinical
symptoms.
