I would worry more about the Triglycerides than the LDL. All are welcome to correct me, but I believe the evidence of high Triglycerides being bad is much stronger than the evidence of high LDL being bad. Neither your Tris or your LDL are atrocious, though. Your HDL is pretty good.
My total Chol. is about where yours is, but I look more at the Trig./LDL ratio. I like this study:
High Ratio of Triglycerides to HDL-Cholesterol Predicts Extensive Coronary Disease
(though bear in mind it looked at people who had various risk factors for heart disease, not just high cholesterol).
In this study, LDL and total cholesterol didn't predict coronary disease very well, but low HDL, high Tris, and high Tri/HDL did.
Also bear in mind you can pick and choose studies to tell the cholesterol story you want, like the story I'm telling you now.
Good news is exercise improves HDL and Trigylcerides, so do the program.
More good news: I ain't a doctor, so you can ignore this post if you want.
