Hi awana,
I am an 81 year old, active woman and was diagnosed with Apical Hcm at 78. At that time I had no symptoms other than palpatations. After diagnosis, I was able to get an appointment in the Hcm clinic at Mayo, Rochester. It is a wonderful place and I am certain you will be reassured that you not only can but should exercise. What exercise that is will be discussed with your Mayo cardiologist. Exercise is not often restricted. I don't run, but I do walk 2 1/2 to 3 miles a day and also do upper and lower body strength exercises several times a week. Six months after my diagnosis, persistent Afib presented its ugly self and that is the only struggle I have really had. Took six months of working to control it. Am now on an antiarrhytmic drug which contols it and keeps me in sinus rhythm. Am hoping it continues to work. Even when I was in constant Afib with heart rates that would go as high as 170, I was able to continue my regular activities although I had much fatigue. So, I believe your worries about exercise may be unfounded. Good luck and I hope you find Mayo Clinic as wonderful a place as I do. I just had my yearly visit yesterday and my cardiologist makes me feel so good about how I am doing.
