The antiarrhythmic mechanism of statins can possibly be explained by their effects on inflammation 45,46,47,48 , antioxidant effects 49,50 , antiarrhythmic effects due to ion channel stabilization 51 , a role in extracellular matrix modulation 52 , an inhibition of synthesis of isoprenoids that are significant for the posttranslational modification of such signalling molecules as Rho, Rac, and Ras…”
