LID - 10.1002/ehf2.14771 [doi] AB - AIMS: As necroptosis involving receptor-interacting protein kinase 3 (RIP3) and dynamin-related protein 1 (Drp1)-mediated signalling is a crucial mechanism of cell loss in heart failure (HF), we aimed to determine the potential diagnostic use of these molecules. METHODS AND RESULTS: The serum samples of the healthy subjects (n = 8) and patients with HF with reduced ejection fraction (n = 31), being subdivided according to the aetiology and New York Heart Association (NYHA) class, were used to measure RIP3 and Drp1 levels by enzyme-linked immunosorbent assay. Although the serum levels of Drp1 in the patients with HF were comparable with those seen in healthy individuals, we found a trend of increase in the levels of RIP3 (P = 0.0697) in the diseased group. These changes were unlikely dependent on the HF aetiology or NYHA class. The circulating RIP3 correlated with neither the main parameters assessing cardiac function (left ventricular ejection fraction, left ventricular end-diastolic diameter, and N-terminal pro-brain natriuretic peptide) nor the marker of inflammation (C-reactive protein). CONCLUSIONS: In this pilot study, findings on serum RIP3 supported the importance of necroptosis in HF pathomechanisms. The potential diagnostic use of circulating RIP3, unlike Drp1, as an additional biomarker of HF has also been indicated; however, further large studies are needed to prove this concept.
