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.
