Doctors revise heart attack prevention guidelines

Fish oil, vitamin D, new cholesterol guidelines: News from an American Heart Association conference over the weekend reveals a lot about what works and what does not for preventing heart attacks and other problems. A new study  showed thatthese do not reduce heart attack risks.

Heart disease is the leading cause of death worldwide. High cholesterol leads to hardened arteries that can cause a heart attack or stroke.

When guidelines were last revised five years ago, they moved away from just using cholesterol numbers to determine who needs treatment and toward a formula that takes into account age, high blood pressure and other factors to more broadly estimate risk.

That was confusing, so the new guidelines blend both approaches, setting targets based on the formula and considering individual circumstances, such as other medical conditions or a family history of early heart disease.
