Angina

Angina is a type of chest discomfort or pain due to poor blood flow through the blood vessels (coronary vessels) of the heart muscle (myocardium). Typically, the chest pain feels like tightness, heavy pressure, squeezing, or a crushing feeling. It may spread to the:

• Arm (most often the left)
• Back
• Jaw
• Neck
• Shoulder

Some people say the pain feels like gas or indigestion.

Some patients have symptoms other than classic angina when there is poor blood flow to the heart which may be called their "anginal equivalent." Examples include shortness of breath, back, jaw or arm pain that occur without chest pain.

There are different types of angina:

• Stable angina
• Unstable angina
• Variant angina

Get medical help right away if you have new, unexplained chest pain or pressure. If you have had angina before, call your health care provider.
