Several observational studies have shown Several observational studies have shown benefit with statin therapy benefit with statin therapy
Statin therapy improves LV EF compared to Statin therapy improves LV EF compared to placebo in pts with CHFplacebo in pts with CHF
Large randomized trials in ACS / CAD Large randomized trials in ACS / CAD suggest that intensive statin therapy may suggest that intensive statin therapy may improve HF, but few details are knownimprove HF, but few details are known ((TNT, TNT, IDEAL, A2ZIDEAL, A2Z))
