@bepeacefulall Thank you for all the helpful information! Our Canadian neighbors navigate a different landscape and I'm glad you chimed in with specific suggestions for Lisa, @lucy4. Lisa, please also consider my previous suggestion to contact the Hypertrophic Cardiomyopathy Association 4hcm.org because they help people navigate their HCM worldwide. In fact, they recently announced they are now active in Portugal! It is true that HCM and HOCM went (and still is) often undiagnosed, even by cardiologists. I realize that my dad probably had an undiagnosed case as I remember his shortness of breath as he aged, died in 1999 but did tell me he had a mitral valve murmur. Grandma was not "feeling well" for a while before she died of an apparent heart attack in the late 1950's. Thank you, again, @bepeacefulall, @boatsforlife and @thehellyousay for all of your valuable inputs.
