I recently had a nuclear stress test and about 24 hours later I became nauseated and salivated and then fainted. This is the 7th time this has happened to me over a 5 year period. Previous episodes happened after straining myself physically and it always is about 24 hours later when I pass out . I can t get a straight answer from my heart doctor ( he diagnosed coronary artery blockage at about 50% and hypertension) but emergency room doctors have diagnosed arterial stenosis and a CTS w/dye shows my aorta to have wrinkles . Is there something wrong with my aortic valve? I have all the classic symptoms (rapid weight gain, swelling of ankles, abdominal bloat, cough, fatigue and shortness of breath etc...)
