Lowering the Risk of Heart Disease
* i( D. P4 m' `: g& jLike millions of other Americans, I come from a family with a histotry of the heart disease. My father had his first three heart attacks when he was only thirty-one. _____________(46) I grew up with heart disease. It was there, but I didn’t take it seriouly.
# @* M9 ~0 v6 l1 I/ ?) YWhen I was thirty-one, my blood cholesterol(胆固醇)level was measured for the first time.It was 311 mg/dl, the doctor told me- an extremely high level that put me at a very high high risk of heart disease, especially with my family history. He sent me to the National Institutes of Health(NIH)to be screened for participation in a clinical trial._____________(47). P4 N- A# b# H6 c$ S7 W
At NIH, physicians explained the degree of risk associated with my blood cholesterol level and the nature of the experiment. This test involves putting a tube through a leg artery(动脉) up to the heart._____________(48)

This experience taught me two lifesaving lessons. First, although I felt fit and strong, I was actually at high risk for heart disease because of my high blood cholesterol level. And with my family histaory, it could not be ignored.________________(50)
