Oh my.... I am so glad that he is feeling better, and that he knew to call someone to get to the hospital right away! Heart attacks can be so scary, and especially for someone only 22 years of age.

Since the docs seem to be leaning toward this being hereditary, is there some tests or meds that YOU should be taking?

My family has a history of cancer and heart conditions on both sides, so we are "doublewhammied". I beleive that one cannot live in fear, but one can do some things to prevent the conditions. Please stay healthy. Prayers for you, your family, and your brother that everyone stays healthy.
