Owering the Risk of Heart Disease

Like millions of other Americans, I come from afamily with a history of the heart disease. My father had his first three heartattacks when he was only thirty-one. I was three years old at that time. I grewup with heart disease. It was there, but I didn’t takeit seriously.

When I was thirty-one, my blood cholesterol(胆固醇)level was measured for the first time. It was 311 mg/dl, the doctortold me an extremely high level that put me at a very high risk of heartdisease, especially with my family history. He sent me to the NationalInstitutes of Health(NIH)to be screened for participation in a clinical trial.The trial was designed to test the effect of lowering blood cholesterol on therisk of heart disease.

At NIH, physicians explained the degree of riskassociated 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. The death rate for the test was only 1 in 100, Iwas assured.

Learning about the risks of the experiment aswell as the risk associated with my raised blood cholesterol level scared thelife out of me. Although I was excluded from participating in the study, theexperience may well have saved my life.

For the first time, I began to realize theseriousness of high blood cholesterol. It was a heart attack just waiting tohappen. But equally important, I got a taste of what it is like to be apatient, to have tests done on me and to think of myself as sick. This was hardto take.

This experience taught me two lifesavinglessons. First, although I felt fit and strong, I was actually at high risk forheart disease because of my high blood cholesterol level. And with my familyhistory, it could not be ignored. Second, I could lower my blood cholesterollevel simply by changing what I ate.
