The risk factors for coronary disease are a positive family history
of coronary disease, smoking, high cholesterol, diabetes, and
high blood pressure. Thus, you do have a risk of developing coronary disease, but I can't quote you actual percentages. I strongly urge you to quit smoking immediately, have your cholesterol level checked by your physician, and practice a "heart-healthy" lifestyle which includes a low-fat, low-cholesterol diet and daily aerobic exercise.
