Effects of interleukin-1 blockade with anakinra on aerobic exercise capacity in patients with heart failure and preserved ejection fraction (from the D-HART pilot study).

ABSTRACT: Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome of exercise intolerance due to impaired myocardial relaxation and/or increased stiffness. Patients with HFpEF often show signs of chronic systemic inflammation, and experimental studies have shown that interleukin-1 (IL-1), a key proinflammatory cytokine, impairs myocardial relaxation. The aim of the present study was to determine the effects of IL-1 blockade with anakinra on aerobic exercise capacity in patients with HFpEF and plasma C-reactive protein (CRP) >2 mg/L (reflecting increased IL-1 activity). A total of 12 patients were enrolled in a double-blind, randomized, placebo-controlled, crossover trial and assigned 1:1 to receive 1 of the 2 treatments (anakinra 100 mg or placebo) for 14 days and an additional
