【 摘 要 】

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 >= 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.
