Prinzmental's angina is usually not dangerous. It is due to spasm of either the coronary arteries themselves or small branches of the coronary arteries. A decrease in blood flow to the heart muscle leads to what we call "angina" or cardiac chest pain. It is very, very rare to have a heart attack in the setting of Prinzmental's angina and there are a few different medications we use to help with the chest pain caused by prinzmental's angina.
Hope this helps. Good luck!!
Thank you for your answer about Prinzmetal angina. I was on a plane and blacked out. My husband said that I stopped breathing. When I came to I had vomited all over the place and was sweating really bad. He said that I was a grey color and I had no pupils, just narrow slits. I was in the hospital for 4 days, but they couldn't find anything wrong. They checked for blood clots, seizures, and heart tests. As you know the Prinzmetal angina doesn't show up on test. The doctors told me that I had this angina back in 2002. But in the past few years, it has gotten worst...Do you have any idea what might of happened to me? I also have an irregular heartbeat.
