Angina occurs when fatty deposits build up in the walls of the
coronary arteries leading to the heart. This causes the walls to become
thinner, and disrupts the flow of blood to the heart muscle. Naturally
this is a serious condition and will cause the sufferer to experience
significant pain in the chest. This pain can easily be mistaken for a
heart attack, and it should be treated as one until it is proven
otherwise.
Chest tightening is one of the main symptoms of an
angina attack. It is alarming but quite typical to see a sufferer
clutching their chest, and crying out in pain. The pain is caused by a
narrowing in the coronary artery, which supply's the heart with oxygen.
The pain can also spread to other areas of the body; like the abdomen,
jaw and arms. These symptoms are remarkably similar to that of a heart
attack, and angina should be treated as one, until it is proven
otherwise.
It is important to then offer the casualty reassurance
to the casualty. At the same time you will need to ascertain from them
if they suffer with the condition. The emergency services should be
called if the answer is no, as they could be suffering a heart attack.
It will always help the first aider if the casualty does tell you that
they suffer with angina. This enables the first aider to move onto the
treatment protocol for angina.
The casualty should be placed into
the half sitting position around about this time, which will protect the
heart from any undue stress.
The emergency services should also
be called if the casualty becomes unconscious. These types of casualty's
should be placed into the recovery position; because this will keep
their airways open whilst you await the arrival of the emergency
services. It must be stressed that the emergency services can actually
be contacted at any time. You will never get in trouble for making the
call, and it does not matter if the condition is wrongly diagnosed.
Remember an ambulance can always be cancelled, or slowed down in the
event of a less serious illness.
The key difference between an
angina attack and that of a heart attack is that angina sufferers will
recover rapidly when rested and when given their medication. Those who
know that they have the condition should carry a Glyceryl triturate
spray with them at all times. This is sprayed into the back of the mouth
and may negate the effects of an attack. First Aiders are not expected
to be trained on the use of these sprays, and should seek professional
medical assistance if they are unsure.
An angina attack is similar
to a heart attack but the key difference is that they typically only
last for 1 - 15 minutes. A casualty suffering with a heart attack will
not get better whilst you are treating them, and often will deteriorate.
The safest bet is to treat the two conditions as a heart attack until
it is proven otherwise.
