I'm 71 and have had symptoms for 20-30 years, gradually worsening. I avoided being honest because I didn't want there to be anything actually wrong as I am fearful of medical interventions and dislike taking medications. Based on a worsening heart murmur, I had an ECHO that showed severe mitral valve regurgitation and other signs of HCOM...I was completely shocked & really fearful at that point. However, I've been on Camzyos since 8/2024 with great results. Heart murmur is barely audible and I rarely have any symptoms. My fears turned out to be groundless and I am so grateful that I now understand why I've felt the way I did. I can only repeat what others emphasize and that is to make sure that you see a cardiologist that is a HCOM specialist.
