I know the risk factors; genetic; high blood pressure, high cholesterol, smoking, poor diet/overweight, lack of exercise. I am from a family of 7 children; 3 of my brothers developed diabetes/heart disease aged 40-45; 3 of my grandparents lived into late 80's and 90's disease free. My parents and my other grandparent all died young from heart disease - they all smoked.

I - in common with all my siblings have high LDL cholerserol. I have normal blood pressure, a reasonable diet, am of normal weight. I gave up cigarettes 20 years ago. However, I am being investigated for heart disease now due to chest pain.

If I am genetically disposed, how much can I influence the outcome by not smoking, eating healthily and exercising. I already walk at least 5 miles per day. If I can only have minimal influence, then I wish the research would tell me that and stop wasting my time!

I would like specific statistics only.......i don't believe the PR anymore!
