Hello, After 10 years of trying to get an answer, I finally got a diagnosis of cardiac preload failure
, low VO2max, and decreased AT. I have shortness of breath, palpitations/heart
racing, chest pains, fatigue, lightheaded. Many many echos--three with bubbles. A PFO showed up on one. Normal cardiac cath--they couldn't see the PFO during the cath. Normal EKGs. Halters normal except for mild sinus tachycardia. Many pulmonary tests--all normal. I have MVP with trace regurgitation.
