I am 45 and I have HCM.i had a defribilator put in 3 years ago and just had open heart surgery to thin my heart in november.I have a stiff heart as well. I feel like my symptoms are getting worse and no better after surgery. I am constantly out of breath, i get lightheaded and dizzy, and blurred vision. Not as many pulptations but when i have them they are bad. Is this normal?? Is this how i will live out my life?? Im already on all the meds.. Please help?
