Do secondhand smoke laws make a difference? The answer may be ''yes'' when it comes to preventing heart attacks.

A new study reveals heart attacks dropped by one-third in one Minnesota county after two smoke-free workplace ordinances went into place.

Lead researchers say the decline was likely due to less secondhand smoke exposure in restaurants and bars. They add, smoke can trigger heart problems due to its effects on arteries and blood clotting.

Scientists say there have been lingering doubts among some people about whether or not the finding was legitimate. But they say they feel they have produced the most definitive results in the study in the Archives of Internal Medicine.
