is a symptom of heart disease. Angina happens when there is not enough blood flow
to the heart muscle. This is often a result of narrowed blood vessels, usually caused
by hardening of the arteries (atherosclerosis).
Most people feel angina symptoms
in their chest. The most common symptom is chest pain or pressure, or a strange feeling
in the chest. But you might feel symptoms in other parts of your body. Some people
feel pain, pressure, or a strange feeling in the back, neck, jaw, or upper belly,
or in one or both shoulders or arms.
Other symptoms of angina include shortness
of breath, nausea or vomiting, lightheadedness or sudden weakness, or a fast or irregular
Angina can be stable or unstable. Stable angina means that you can
usually predict when your symptoms will happen. You probably know what things cause
your angina. Angina may be caused by activity or exertion. It also may occur during
exposure to cold or times of emotional stress. Stable angina can be relieved by rest
or nitroglycerin. Unstable angina means that your symptoms have changed and are not
following your typical pattern of stable angina. Unstable angina may mean that you
are having a heart attack.
If you have angina, pay attention to your symptoms,
know what is typical for you, learn how to control it, and understand when you need
to get treatment.
