Depends on Particles: Despite your results, cardiovascular (cvd) risk is related to the number of LDL and HDL particles (ldl-p, hdl-p). Ldl can be estimated by cholesterol (ldl-c) or measured by particle number (ldl-p). Ldl-c and ldl-p do not equally predict cardiovascular risk. When ldl-c and ldl-p values disagree (due to cholesterol variability per particle) cvd risk tracks with LDL particle number, not ldl-c values.

Sounds good.: It sounds like you're doing it all right, and your numbers seem to reflect that. Keep up the good work. Start young and build a healthy future.
