Heart Failure is Associated With Impaired Anti-Inflammatory and Antioxidant Properties of High-Density Lipoproteins

Oxidative stress and inflammation are hallmarks of the heart failure (HF) disease state. In the present study, we investigated the inflammatory/anti-inflammatory characteristics of high-density lipoproteins (HDL) in patients with HF. Ninety-six consecutive patients with systolic HF were followed in an advanced HF center, and 21 healthy subjects were recruited. Plasma was tested for HDL inflammatory index (HII) using a monocyte chemotactic activity assay, with HII >1.0 indicating proinflammatory HDL. We found significantly increased inflammatory properties of HDL in patients with HF (median HII 1.56 vs 0.59 in controls; p
