    Abstract:
    BACKGROUND: No therapy has been shown to improve survival in heart failure (HF) with a normal ejection fraction (EF). There are plausible reasons to hypothesize that statins may be of benefit in HF with a normal EF. METHODS AND RESULTS: We evaluated 137 patients with HF and an EF > or =0.50. The effect of treatment received at study entry on survival was determined. During a follow-up of 21+/-12 months, 20 deaths were observed. Treatment with an ACE inhibitor or receptor blocker, beta-blocker, or calcium blocker had no significant effect on survival. In contrast, treatment with a statin was associated with a substantial improvement in survival (relative risk of death [95% CI] 0.22 [0.07 to 0.64]; P=0.006). Patients receiving statins had higher baseline LDL cholesterol than those not receiving statins (153+/-45 versus 98+/-33 mg/dL, P<0.01). After statin therapy, LDL cholesterol levels fell to a similar level (101+/-32 mg/dL) as in patients not receiving statins (98+/-33 mg/dL). After adjustment for differences in baseline clinical variables between groups (hypertension, diabetes, coronary artery disease, and serum creatinine), statin therapy was associated with lower mortality (adjusted relative risk of death [95% CI] 0.20 [0.06 to 0.62]; P=0.005). Similarly, after propensity matching, statin therapy was associated with improved survival (log-rank 6.12; P=0.013) and a trend toward improved survival without cardiovascular hospitalization (log-rank 3.02; P=0.082). CONCLUSIONS: Statin therapy may be associated with improved survival in patients with HF and a normal EF.
