Strange Lipid Panel Results

I'm 48 Female. I was diagnosed with CAD in July - 3 Vessel including 40% blockage in Left Main.  Since then I have tried to do everything right with hopes of getting reversal.  dropped 30 pounds, exercise daily, limit fat to 10% and under 20 grams.  No Alcohol and only sweets are fruit.  Don't eat Bread, Rice, chips and other high carb items.   Take 10 mg of Crestor.  Take Vitamin B Complex and 4 Fish Oil capsules.  Even take fiber supplements.

Here's my Lipid Panel Info comparing July to October-

Triglycerides UP from 374 to 386
Total Cholesterol down from 293 to 151 - a great start
HDL Cholesterol DOWN from 55 to 36 - I am really worried about this
LDL Cholesterol down from 163 to 38 - getting too low?

Has anyone seen such a mixed result?  Any ideas what might have caused this?  I'm being retested in mid-November but for now I'm worried and it's hard to stay motivated.  

Thanks,
Mea
