Abstract

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. Compared to S-HFpEF, AD-HFpEF patients had higher levels of PTX3 (3.08 ng/mL versus 1.27 ng/mL, P < 0.0001), interleukin-6 (4.14 pg/mL versus 1.71 pg/mL, P < 0.0001), tumor necrosis factor-alpha (11.54 pg/mL versus 8.62 pg/mL, P=0.0015), and high-sensitivity C-reactive protein (11.90 mg/dL versus 3.42 mg/dL, P < 0.0001). Moreover, highsensitivity C-reactive protein, interleukin-6 and PTX3 levels were significantly higher in AD-HFpEF compared with S-HFpEF patients admitted for decompensated HF within the previous year. PTX3 was positively correlated with left atrial volume index (r=0.41, P=0.0017) and left ventricular mass (r=0.26, P=0.0415), while tumor necrosis factor-alpha was inversely correlated with E/A ratio (r=-0.31, P=0.0395). Conclusions--Levels of pro-inflammatory biomarkers are strikingly higher in AD-HFpEF compared with S-HFpEF patients. PTX3 and tumor necrosis factor-alpha are correlated with echocardiographic-Doppler evidence of diastolic dysfunction. Taken together these data support the concept that a heightened pro-inflammatory state has a pathophysiologic role in the development of AD-HFpEF.
