Hi Kate - our conversation is really helpful. The only symptoms that I have are breathlessness and occasional fatigue that come on suddenly after I have been running around all day. I am glad that you are feeling a lot better. Have you been on calcium channel blockers and what was that like? side effects? My doc wants to skip over beta blockers because they are, apparently, correlated with depression which I have had on and off all my life and do not want to fool around with - my meds for that are now perfect. It is good to hear about your experience with Camzyos - scary symptoms but I won't be as alarmed if they happen. The REMS team will be on top of that, I hope. I don't know what me gradient is - will ask doc when I email him later. What gradient is good? bad? range? Thanks so much! Joyce
