My thickness is at 19 mm and my LVOT gradient is at 122. I was at 52 in 2021 - its increased that quickly. Im on 50 mg metoprolol 3 times a day. Im 63 now, diagnosed at 58 too. Had issues for years but no one could pinpoint. Got dizzy spell at work at they took me in thinking it was heart attack. Im glad you are doing better and zero symptoms! ❤️
