If you are asking why statins: When you have high cholestrol (the LDL type), triglycrides (spell), can be a factor in developing plague in your arteries. This can cause high blood pressure and the plaque can lead to clotting and reducing flow of blow to heart leading to a heart attack AND heart failure.

Statin drugs lower the ability of liver to make cholestrol (which is does normally) which lowers your cholestrol.

If you are asking why Atorvastatin specifically it is just the generic form of brand name statins and much much cheaper. I have Federal BCBS prescription coverage and I get my 90 days supply free (meaning I do not have the normal co-pay at CVS).

My heart failure doctor also asked me to take Fish Oil saying it would lower my tryglecerides and it did. The fish oil is OTC.
