Recent data suggest that guideline directed medical treatment of patients with heart failure with reduced ejection fraction (HFrEF) might improve clinical outcomes in patients with heart failure (HF) up to a left ventricular ejection fraction (LVEF) of 55-65%, whereas patients with higher LVEF do not seem to benefit.

Abstract
Recent data suggest that guideline directed medical treatment of patients with heart failure with reduced ejection fraction (HFrEF) might improve clinical outcomes in patients with heart failure (HF) up to a left ventricular ejection fraction (LVEF) of 55-65%, whereas patients with higher LVEF do not seem to benefit. Recent data have shown that LVEF may have a U-shaped relation with outcome, with poorer outcome also in patients with supranormal values. This suggests that patients with supranormal LVEF may be a distinctive group of patients METHODS AND RESULTS: RELAX AHF-2 was a multicenter, placebo-controlled trial on the effects of serelaxin on 180-day cardiovascular (CV) mortality and worsening HF at day 5 in patients with acute HF. Echocardiograms were performed at hospital admission in 6128 patients. 155 (2.5%) patients were classified as HFsnEF (LVEF>65%), 1440 (23.5%) as HFpEF (LVEF 50-65%), 1353 (22.1%) as HFmrEF (LVEF 41-49%) and 3180 (51.9%) as HFrEF (LVEF<40%). Patients with HFsnEF compared to HFpEF were more often women, had higher prevalence of non-ischemic HF, had lower levels of natriuretic peptides, were less likely to be treated with beta-blockers and had higher blood urea nitrogen plasma levels. All-cause mortality was not statistically different between groups, although patients with HFsnEF had the highest numerical rate. A declining trend was seen in the proportion of 180-day deaths due to CV causes from HFrEF (290/359, 80.8%) to HFsnEF (14/24, 58.0%). The reverse was observed with death from non-cardiovascular causes. No treatment effect of serelaxin was observed in any of the subgroups.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
