Pro-Inflammatory Biomarkers in Stable Versus Acutely Decompensated Heart Failure With Preserved Ejection Fraction.

Background: Underlying inflammation has been increasingly recognized in heart failure with a preserved ejection fraction (HFpEF). In this study we tested the hypothesis that pro-inflammatory biomarkers are elevated in patients with acutely decompensated HFpEF (AD-HFpEF) compared with patients with stable HFpEF (S-HFpEF).

Methods And Results: Using a post hoc analysis the serum biomarkers tumor necrosis factor-alpha, high-sensitivity C-reactive protein interleukin 6 and pentraxin 3 (PTX3) and clinical, demographic, echocardiographic-Doppler and clinical outcomes data were analyzed in HFpEF patients enrolled in NHLBI Heart Failure Research Network clinical trials which enrolled patients with either AD-HFpEF or S-HFpEF.

Abundance, localization, and functional correlates of the advanced glycation end-product carboxymethyl lysine in human myocardium.

Advanced glycation end-products (AGEs) play a role in the pathophysiology of diabetes mellitus (DM) and possibly hypertension (HTN). In DM, AGEs accumulate in myocardium. Little is known about AGEs in myocardium.
