I am a 38 y/o white female and have been experiencing increasing shortness of breath, both upon exertion and at rest. Within the last several months I have also experienced chest pain and pressure of varying degrees, mostly slightly left of midsternal and sometimes radiating to the left shoulder. I had a normal ECG and was prescribed xanax for "anxiety", and then prevacid for GERD. Neither helped. Finally, I was referred for a stress echo which revealed abnormal ejection fraction slightly less than 50%, and trace mitral valve regurgitation. The cardiologist did not feel it was serious enough to treat at this time. I am still experiencing all of the same symptoms, especially shortness of breath, even at night. I have been sleeping poorly, and using several pillows to prop myself up. Walking up a flight of stairs, or eating, leaves me unable to speak for a few minutes because I am out of breath. Should I request another opinion or wait and see how things go? I should add that I am not necessarily athletic, but not unhealthy or overweight, 5'3" and 123 lbs.
