00:00.740 --> 00:03.220
Angina is chest pain or discomfort that

00:03.220 --> 00:05.387
results from coronary artery disease .

00:05.387 --> 00:07.164
It often feels like pressure or

00:07.164 --> 00:09.498
squeezing in the chest . Captain Miller .

00:09.498 --> 00:11.498
What can you tell us about angina ?

00:11.740 --> 00:13.800
Well , dr Mansfield angina pain

00:13.800 --> 00:15.790
typically lasts only a few minutes

00:15.800 --> 00:18.160
while most people experience angina as

00:18.160 --> 00:20.490
pressure in the chest pain can also

00:20.490 --> 00:23.370
occur in the shoulders , arms , neck ,

00:23.380 --> 00:26.560
jaw or back . For some angina pain may

00:26.560 --> 00:29.160
even feel like indigestion . There are

00:29.160 --> 00:31.104
two main types of angina caused by

00:31.104 --> 00:33.870
coronary artery disease , stable angina

00:33.880 --> 00:36.760
and unstable angina . Stable angina ,

00:36.760 --> 00:38.870
which is most common occurs when the

00:38.870 --> 00:41.037
heart is working harder than usual due

00:41.037 --> 00:43.370
to physical activity , emotional stress

00:43.380 --> 00:46.070
or smoking . This type of angina has a

00:46.070 --> 00:48.014
regular pattern , meaning there is

00:48.014 --> 00:50.237
little variation and how often the pain

00:50.237 --> 00:52.190
occurs , how severe it is and what

00:52.190 --> 00:54.610
factors trigger it . A person with

00:54.610 --> 00:56.832
stable angina can learn the pattern and

00:56.832 --> 00:59.000
predict when the pain will occur . The

00:59.000 --> 01:01.000
pain usually goes away within a few

01:01.000 --> 01:03.000
minutes of resting or taking angina

01:03.000 --> 01:05.960
medication , unstable angina , also

01:05.960 --> 01:07.970
called acute coronary syndrome ,

01:08.130 --> 01:10.520
doesn't follow a pattern . It may occur

01:10.520 --> 01:12.464
more often and be more severe than

01:12.464 --> 01:14.410
stable angina , and it may not be

01:14.410 --> 01:16.440
triggered by a specific factor like

01:16.440 --> 01:19.120
physical exertion or stress . In many

01:19.120 --> 01:21.400
cases , rest or medication may not be

01:21.400 --> 01:23.790
able to relieve the pain unstable .

01:23.790 --> 01:26.050
Angina is very dangerous and requires

01:26.050 --> 01:28.600
emergency treatment . It's a sign that

01:28.600 --> 01:30.900
plaque in the artery has ruptured and a

01:30.900 --> 01:32.900
blood clot has partially or totally

01:32.900 --> 01:35.122
blocked an artery , which means a heart

01:35.122 --> 01:37.610
attack may happen soon . A third type

01:37.610 --> 01:39.930
of angina , called variant , or prince

01:39.930 --> 01:42.510
metals . Angina is caused by a spasm In

01:42.510 --> 01:45.370
a coronary artery variant , Angina can

01:45.370 --> 01:47.537
occur both in people who have coronary

01:47.537 --> 01:49.450
artery disease and in those who don't .
