I have a friend who is a very fit 49 yr old white female. She works out daily, mostly cardio (walking, hr long spin class, eliptical). About 2 weeks ago she began having tightness in her chest and some pain. Also had a drop in energy and feels tired a lot and gets winded easily at times. Her family has a history of heart disease.Two days ago she had a clean EKG and was told her heart is fine.
We is a non-smoker, social drinker, is 5'6", 130 lbs
