Combined Neuro-Humoral Modulation and Outcomes in Patients with Chronic Heart Failure and Mildly Reduced or Preserved Ejection Fraction
Abstract
Pharmacotherapy of chronic heart failure with mildly reduced (HFmrEF) and preserved ejection fraction (HFpEF) remains challenging. We aimed to assess whether combined neuro-humoral modulation (NHM) (renin–angiotensin system inhibitors, betablockers, mineralocorticoid receptor antagonists) was differentially associated with outcome according to phenotype and age groups. Between 1999 and 2018 we recruited in a nationwide cardiology registry 4707 patients (HFmrEF n = 2298, HFpEF n = 2409) from three age groups: trend = 0.001); the reverse was observed among HFpEF (ptrend = 0.005). Triple NHM increased over time in both phenotypes (all p for trend p = 0.032) and HFpEF (HR 0.700, 95%CI 0.499–0.983, p = 0.039), with no interaction between NHM treatment and age groups (p = 0.58, p = 0.80, respectively). In a cardiology setting, among HF outpatients with EF > 40%, triple NHM treatment increased over time and was associated with better patient outcomes.
