Prevalence and Associations of Systemic Inflammation in Heart Failure Across the Spectrum of Ejection Fraction

JACC Heart FailPublished

  • Pooled cross-sectional analysis of 3 randomised trials

Authors' conclusion

Systemic inflammation is present in one-half of patients with HF, and is associated with excess body fat, chronic kidney disease, albuminuria, and diabetes, and increases with comorbidity burden. These relationships are not specific to HFpEF/HFmrEF but are also common to HFrEF

Study context

Population
Patients with heart failure (HF) in 3 large outcome trials (SELECT, SOUL, FLOW)3 trials
Participants
3,204 / 1,246 / 1,018
Comparison
Heart Failure with Preserved Ejection Fraction (HFpEF) vs Heart Failure with Mildly Reduced Ejection Fraction (HFmrEF) vs Heart Failure and Reduced Ejection Fraction (HFrEF)
  • HFpEFn = 3,204
  • HFmrEFn = 1,246
  • HFrEFn = 1,018
Outcome
Prevalence of systemic inflammation (hsCRP ≥2 mg/L)

Pooled result

As reported in the abstract

Elevated hsCRP (≥2 mg/L)

Further pooled results

Correlates of higher high-sensitivity C-reactive protein (hsCRP)

Higher hsCRP more likely female, obesity, DM, lower eGFR, higher albuminuria, COPD; no meaningful differences by HF subtype

hsCRP vs EF and comorbidity count

hsCRP unrelated to EF
R2 < 0.001; P = 0.73
hsCRP increased linearly with number of comorbidities, all HF subtypes
R2 = 0.94; P < 0.001
