I was recently diagnosed with this condition and it is termed idiopathic or unknown in origin. I am 33 years old and don t smoke. I also have fibromyalgia. I was hoping someone could give me some idea as to what I can look forward to as far as symptoms and warning signs so I don t call the dr or go to the er for no reason. Also, what questions should I ask the cardiologist so I am not wasting his time on things I don t need to know. I forgot to ask about energy levels...I have 0 energy. I am on Lotensin, Lopressor, Plavix, aspirin and Hydroxyzine. Thanks to kimmy...I have actually had a cardia catheterization, echocariogram and several ekgs...the dr hasn t been all that helpful about information just don t work, don t have any activity and don t get pregnant, and a low sodium diet!
