Narrator: This is Science Today. Angina is a term used by doctors to describe pain or discomfort that results from the heart not getting enough oxygen. Dr. Tony Chou, a cardiologist at the University of California, San Francisco says different people have different symptoms.
Chou: Some people it's shoulder pain or arm pain, it might radiate. Some people it's neck pain, so it's really different for every patient. The heart has a different set of nerve endings and so depending on how you're wired, you might feel something totally unpain-like but that's what we call angina. And most of the time, patients who have angina, they're familiar with what their angina is.
Narrator: While many of the treatments, such as angioplasty or nitro glycerin patches work for patients, Chou says many just get used to their symptoms.
Chou: As a cardiologist, I tell them that that's not a good response to your disease. You want to be able to do what you are fully capable of doing and not have angina hold you back.
