Hi, I'm 20 and my dad died last Monday of a heart attack driving home from work. I'm just slightly concerned about my heart now, and what I can do now and in the future.

My dad was 48, and the coroner said that he had heart disease. I know it runs in his family because his dad died in 1985 when he was 75 of a heart attack (caused by heart disease), and his dads two sisters both died of heart attacks.
