To investigate the effect of valsartan in the Valsartan-Heart Failure Trial (Val-HeFT) when added to angiotensin-converting enzyme inhibitor (ACEi) alone in patients with heart failure (HF).
Subjects in Val-HeFT receiving ACEi but not beta-blocker at baseline were analysed; 1532 were assigned to valsartan and 1502 assigned to placebo. Primary outcome events (all-cause mortality, hospitalisation for adjudicated heart failure, sudden death with resuscitation and need for >4 h of parenteral therapy for worsening heart failure) were monitored.
Mortality was not affected by valsartan but morbidity endpoints were significantly reduced (36.3% in placebo, 31.0% in valsartan, p=0.002) in patients receiving an ACEi but no beta-blocker. Quality of life (QOL) was significantly improved, ejection fraction (EF) significantly increased, left ventricular (LV) diameter significantly reduced and plasma B-type natriuretic peptide, norepinephrine and aldosterone levels significantly reduced with valsartan compared to placebo. The morbidity benefit was significant in patients on ACEi doses below the median (22% reduction, p=0.003) and not statistically significant in those receiving ACEi doses above the median (14% reduction, p=0.143).
Valsartan reduces heart failure hospitalisations and slows LV remodelling in patients treated with an ACEi in the absence of beta-blockade, particularly in those on lower doses of ACEi.
在缬沙坦-心力衰竭试验(Val-HeFT)中,研究缬沙坦单独添加到已接受血管紧张素转换酶抑制剂(ACEi)治疗的心力衰竭(HF)患者中的效果。
对Val-HeFT中基线时接受ACEi但未接受β受体阻滞剂治疗的受试者进行分析;1532例被分配至缬沙坦组,1502例被分配至安慰剂组。监测主要结局事件(全因死亡率、因判定的心力衰竭住院、复苏成功的心脏性猝死以及因心力衰竭恶化需要>4小时肠外治疗)。
在接受ACEi但未接受β受体阻滞剂治疗的患者中,缬沙坦对死亡率无影响,但发病终点显著降低(安慰剂组为36.3%,缬沙坦组为31.0%,p = 0.002)。与安慰剂相比,缬沙坦显著改善生活质量(QOL),显著增加射血分数(EF),显著减小左心室(LV)直径,并显著降低血浆B型利钠肽、去甲肾上腺素和醛固酮水平。在接受低于中位数剂量ACEi的患者中,发病获益显著(降低22%,p = 0.003),而在接受高于中位数剂量ACEi的患者中,发病获益无统计学意义(降低14%,p = 0.143)。
在未使用β受体阻滞剂的情况下,缬沙坦可减少接受ACEi治疗患者的心力衰竭住院次数,并减缓左心室重构,尤其在接受较低剂量ACEi的患者中。
