Hi Chit,
It can be very confusing. The data for people with known coronary artery disease (CAD), people with major risk factors for CAD (in the heart protection study), and people after heart attacks is very good. Just about everyone with CAD or previous heart attack should be on a statin, regardless of there LDL barring contraindications to the medication. If you have CAD or major risk factors for CAD (diabetes plus one other risk factor), you should probably be on a statin.
If you are taking a statin for prevention of future events, don't have many risk factors and haven't had a heart attack, it is reasonable to treat the triglycerides only. Your LDL is very good at 93, although this may be while you were on the statin.
Management of lipids can be very complicated and has to be done in the context of your risk factor profile. I hope this response helps.
Oat bran (not oat meal) is harmless. Read the 8 week cholesterol cure...A great book.
Thanks
