A recent study in the Netherlands investigated the association between lifestyle factors and the risk of coronary heart diseases in individuals with or without a family history of MI.

It was found that lifestyle factors affected the risk of both the diseases. For both the diseases, smoking increased the risk while alcohol consumption was associated with a protective effect. The difference in the risk factors was only statistically significant for smoking. The number of cigarettes smoked was directly proportional to the risk of both coronary diseases.
In men, an inverse association was found with physical activity during relaxation which seemed to be stronger for the risk of UAP than of AMI. On the other hand in women, physical activity during leisure time was associated with an increased risk of both AMI and UAP. Nonetheless, the highest levels of risk factors were found in individuals with a positive family history and the most unfavorable level of the lifestyle factors.
The effects of the lifestyle factors on the risk of both the coronary diseases were the samefor subjects, with and without a positive family history.
