I have IHSS also known as hypertrophic cardiomyopathy Eveyone in my family was asked to be tested with an echo cardiogram. My son has to be tested every couple years, I was told I had a famil type of HCM but know one in my family has tested positive yet.
If heart problems run in your family it may be a good idea to have them be checked
I wouldn't think so unless they have symptoms of heart problems.
