Good evening Leo! So glad you found this site. As a HOCM patient you need to have other relatives get echocardiograms to see who else in your family has this hereditary disease. Adults who are negative need to be tested every 5 years. Kids under 18 need to be tested every year. Nobody knows when they will show signs of being positive for HCM.
I was 67 when I was diagnosed, but my breathing was labored for many years and was miss diagnosed as being an asthmatic. My Father was miss diagnosed with labored breathing and it was blamed on cigarette smoking.
Please have all of your relatives tested for HCM. Once I was diagnosed, other relatives have also been diagnosed.
Best to You!!
Jim
