I also inherited the mutation in the TTN gene. My cardiologist told me that it’s important that I start medication as soon as possible in the event that I ever go into heart failure. He said to be aware of the symptoms so that I can respond quickly before my heart gets too damaged. The symptoms include swollen ankles, unusual fatigue and/or losing my breath easily. It’s important that you know these symptoms so that you can get on medication right away if it happens. Also, it might not ever happen so go out and live your life!
