ABSTRACT
AIMS:
Although body mass index (BMI) is the most commonly used anthropometric measure to assess adiposity, alternative indices such as the waist-to-height ratio may better reflect the location and amount of ectopic fat as well as the weight of the skeleton. METHODS ANDRESULTS:
The prognostic value of several alternative anthropometric measures was compared with that of BMI in 1116 patients with non-ischaemic heart failure with reduced ejection fraction (HFrEF) enrolled in DANISH. The association between anthropometric measures and all-cause death was adjusted for prognostic variables, including natriuretic peptides. Median follow-up was 9.5 years (25th-75th percentile, 7.9-10.9). Compared to patients with a BMI 18.5-24.9 kg/m2 (n = 363), those with a BMI ≥25 kg/m2 had a higher risk of all-cause and cardiovascular death, although this association was only statistically significant for a BMI ≥35 kg/m2 (n = 91) (all-cause death hazard ratio [HR] 1.78, 95% confidence interval [CI] 1.28-2.48; cardiovascular death HR 2.46, 95% CI 1.69-3.58). Compared to a BMI 18.5-24.9 kg/m2, a BMI <18.5 kg/m2 (n = 24) was associated with a numerically, but not a significantly, higher risk of all-cause and cardiovascular death. Greater waist-to-height ratio (as an exemplar of indices not incorporating weight) was also associated with a higher risk of all-cause and cardiovascular death (HR for the highest vs. the lowest quintile all-cause death HR 2.11, 95% CI 1.53-2.92; cardiovascular death HR 2.17, 95% CI 1.49-3.15).CONCLUSION:
In patients with non-ischaemic HFrEF, there was a clear association between greater adiposity and higher long-term mortality. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov NCT00542945.
