Statins have revolutionised the treatment of coronary artery disease .Intensive lipid lowering is the fundamental prerequisite in the management of both acute and chronic coronary syndromes. One question  is  always difficult to answer , ( rather reluctant to find the answer )   “The effect of statins on the HDL cholesterol”. Logic and the mechanisms of action would suggest HDL is not much affected , but in reality  I believe , in a given patient statins  do  reduce the HDL by at-least 10-20 % .This might have some significance. However ,  the marked  reduction in LDL  may nullify the adverse effects of lowering HDL.   Does this happen in all

What does the scientific evidence say ?

It says the opposite .  It seems  HDL is raised by statins that too significantly . The following paper also  suggests mechanism of  HDL  elevation by statins .It is Independent  to that of LDL reduction , I believe .

This JAMA article  adds more evidence

This paper  from  the  premier  Journal  of   Lipid research  agrees  to the   mechanism of  HDL reduction by statin  is a complex process  but still  it vouches for it .

In spite of  all these  evidence . . .   it  remains a  huge suspect . . . from my personal point of  view ( My patients are  my evidence !  )

Coming soon

The above articles also raise an important  concept of dysfunctional HDL.  Simple raise  in HDL is not suffice . . .it should be functional as well !
