In fact the risk of a heart attack in a diabetic woman is the same as that of a non-diabetic man. The risk of a heart attack in a diabetic woman is several times that of the non-diabetic woman, so it's very important that all risk factors are modified, particularly the LDL cholesterol. It is less likely that a woman will have a heart attack if she is pre-menopausal, but it still occurs particularly in women who smoke. For half of women who have heart attacks before menopause in the Nurses' Health Study, their only risk factor was cigarette smoking. My father had 2 heart attacks.
Family history is an extremely important risk factor.
We are generally concerned with parents who have premature disease. This would be defined as a father who had heart disease before age 45 or a mother before age 55. In women, it's important to look at both good and bad cholesterol fractions. Often women will have higher HDLs but the goal for LDL is the same. Without atherosclerosis or significant risk factors, the LDL should optimally be less than 130.
