DEAR DOCTOR K: I have high levels of HDL cholesterol -- the "good" cholesterol. I was happy about that, but now I hear that medicines raising your HDL levels don't seem to help. Should I be disappointed?
DEAR READER: The HDL cholesterol story is complicated. It has been solidly established that people who have high levels of LDL (bad) cholesterol have a higher risk of developing heart disease. Moreover, it has been solidly established that treatments that lower LDL cholesterol reduce the risk of developing heart disease.
