I need help, more so with my anxiety about the issue but either way assume insight would be much appreciated. I want to know how someone has a heart attack without clogged arteries and how likely or common is it. I convince myself that the symptoms I have are related to a heart attack or heart issue even though I've had every test I can imagine more than once; ekg, 24 hour monitor, 30 day event monitor, stress test, echo, and ct ang iogram. but I've read about a coronary spasms from stress causing heart attacks. how worried should I be. I'm so stressed, please inform me the best you can. thank you so much.
