Study: High HDL Not Linked to Reduced Heart Attack Risk

Your doctor has probably told you raising your good cholesterol will decrease the chances you'll have a heart attack.

Now, a new study out of Harvard Medical School says maybe that isn't the case.

It says genetic tests haven't shown a link between higher HDL and a lower risk. HDL is the so-called "good" cholesterol.

One of the study's authors tells Web MD that HDL is important tool for figuring out heart attack risk, but he says this research raises questions as to whether there are benefits to taking drugs to increase those levels.

On the flip side, studies have shown that high LDL or bad cholesterol, is linked to an increased risk of heart attacks.

So the takeaway message from doctors is to definitely lower your LDL.

The study is published in the journal Lancet.
