Sorry to hear about your diagnoses but it’s a positive you now have a diagnoses as this condition often goes undetected, only found once it’s too late. My brother was diagnosed at 10 years old with hypertrophic cardiomyopathy. My grandmother suffered from it, and due to it be passed on through a genetic mutation, we were scanned yearly as children. My dad was told he didn’t have it, which we’ve now found out isn’t the case, he must carry the mutated gene, however it hasn’t yet developed any problems, his heart is larger than normal but he’s a tall/broad 6ft something man so isn’t too worrying. My brothers heart thickness was irregular but did not grow much over his younger years, so he was on beta blockers, the didn’t go down well as he put a lot of weight on and got him down mentally . He didn’t display many symptoms of this affecting him so he stopped tablets as a teen, worst mistake he made. No treatment combined with an unhealthy/risky life he is now 32 years old and recently had open heart surgery due to an major obstruction, left any longer he wouldn’t have made it. He also had a internal defibrillator fitted, however due to his age this is a side one, less complicated if needed fixed or changed later in life. I show no signs at all so continue scans to check, these are every 5 years as my doctor won’t agree to genetic mutation testing, which is a total pain in back side as it feels like a waiting game to see if symptoms appear or not. With all that said, our family live a very normal life. My dad and brother are very avid bikers, total thrill seekers. They haven’t let it stop them doing anything, some they were advised against. My only concern is it being genetic, so if you’ve got it, it’s likely one of your parents did, therefore possibility as sibling also contracted the mutated gene, it’s 50/50 chance, however more likely in males. You should discuss this with gp, and advise anyone possibly affected to get tested. They can do this by speaking to gp, explain situation and they will refer them to cardiologist. Hope this helps, and you keep in good health
