Thanks for your health concerns; it is quite important to rule out that your shortness of breath
is not due to a chronic cardiopulmonary process, particularly since you had a son who passed away from hypertrophic cardiomyopathy; this in by itself is a qualifier for screening with an ultrasound
of the heart. Other tests, such as an exercise stress test
may be required.
