Theory may explain why more men get heart disease

A new study in the Lancet Medical Journal shows that some men may inherit a higher risk for heart disease directly from their fathers.

Researchers say this is significant because it ties heart disease risk to the male "Y" chromosome.

Previous studies have suggested this the "Y" chromosome doesn't have much to do with inheritance beyond providing male sex characteristics.

Some researchers are even suggesting that family history may be a stronger predictor of heart disease risk for men than for women.

Overall, scientists say the study is intriguing but not definitive and that more research is needed.
