Abstract
Background
Right ventricular (RV) dysfunction (RVD) in heart failure (HF) with preserved ejection fraction (HFpEF) is recognised late and associated with poor outcomes. We aimed to identify biomarkers associated with RV dysfunction in HFpEF and evaluate their prognostic significance.
Methods
77 patients with HFpEF were enrolled from a prospective, multicentre study. At baseline, patients underwent echocardiography, cardiac magnetic resonance (CMR) imaging and laboratory testing. They were followed up for the composite outcome parameter of all-cause mortality and HF hospitalisation. RVD was defined as RV ejection fraction (RVEF) < 45 % on CMR. Proteomics analysis was performed using Olink proteomics multiplex panels (CVDII, CVDIII, Inflammatory and Immuno-oncology) with further verification on immunoassay analysis.
Results
19 patients with HFpEF (25 %) had RVD. The Olink proteomic analysis identified carbohydrate antigen 125 (CA125) as the most differentially abundant in plasma of patients with HFpEF and RVD as compared to those without RVD, which corroborated with further immunoassay analysis − median CA125 in patients with RVD was 23 kU/L [21–47] vs. 16 [[12], [13], [14], [15], [16], [17], [18], [19], [20]] in patients without RVD (p < 0.001). Log-normalised CA125 (LnCA125) was associated with worse RVEF (r = −0.29, p = 0.03) and predicted worse clinical outcomes [HR 2.28 (1.28–4.07) for the composite outcome of all-cause mortality and HF hospitalisation] adjusted for age, gender, body mass index, LVEF, RVD, atrial fibrillation, renal function and NTproBNP.
Conclusion
Targeted proteomic analysis reveals CA125 as a biomarker for RVD in a HFpEF population. Higher serum CA125 concentration, but not NTproBNP, was associated with an increased risk of all-cause mortality and HF hospitalisation.
期刊介绍:
IJC Heart & Vasculature is an online-only, open-access journal dedicated to publishing original articles and reviews (also Editorials and Letters to the Editor) which report on structural and functional cardiovascular pathology, with an emphasis on imaging and disease pathophysiology. Articles must be authentic, educational, clinically relevant, and original in their content and scientific approach. IJC Heart & Vasculature requires the highest standards of scientific integrity in order to promote reliable, reproducible and verifiable research findings. All authors are advised to consult the Principles of Ethical Publishing in the International Journal of Cardiology before submitting a manuscript. Submission of a manuscript to this journal gives the publisher the right to publish that paper if it is accepted. Manuscripts may be edited to improve clarity and expression.
