Supplementary File Laboratory Analyses: NT-proBNP NT-proBNP was measured on the Dimension Vista 500 Intelligent Laboratory System (Siemens Healthcare Diagnostics, Deerfield, IL) using a one-step homogeneous, sandwich chemiluminescent immunoassay based on LOCI® technology. The limit of detection of NT-proBNP assay is 0.8 pg/mL. Typical within-lab imprecision for the assay is <3% CV at an NT-proBNP concentration from 120- 5000 pg/mL. Troponin I Precommercial ultrasensitive troponinI (TnI) was measured on the Dimension Vista 500 Intelligent Laboratory System (Siemens Healthcare Diagnostics, Deerfield, IL) using a one-step homogeneous, sandwich chemiluminescent immunoassay based on LOCI® technology. The lower limit of detection of the troponin assay is 0.015 μg/L and the 10% CV is <0.04 μg/L. sFlt-1 sFlt-1 was measured using a prototype ARCHITECT immunoassay (Abbott Laboratories, Abbott Park, IL) utilizing the 2-step chemiluminescent microparticle immunoassay (CMIA) format. The sFlt-1 immunoassay measures both free and bound sFlt-1, with an measuring range of 15 to 50,000 pg/ml. The intra- and interassay coefficients of variation (CV) ranged from 1.3% to 5.2% and 1.9% to 5.9%, respectively. PlGF PlGF was measured using a prototype ARCHITECT immunoassay (Abbott Laboratories, Abbott Park, IL) utilizing the 2-step chemiluminescent microparticle immunoassay (CMIA) format. The PlGF immunoassay measures the free, not bound PlGF-1 with approximately 20% cross-reactivity with the PlGF-2 isoform, with an measuring range from 1 to 1,500pg/ml. The intra- and interassay CV ranged from 1.4% to 6.7% and 1.8% to 6.7%, respectively. hsCRP hsCRP was measured using the MULTIGENT Vario assay on the ARCHITECT ® system (Abbott Laboratories, Abbott Park, IL), which is a latex immunoassay. The lower limit of detection if 0.01mg/dL. The total CV was ≤ 6%. MPO MPO was measured using a prototype ARCHITECT immunoassay (Abbott Laboratories, Abbott Park, IL) utilizing the 2-step chemiluminescent microparticle immunoassay (CMIA) format.

Gal-3 Gal-3 was measured using a prototype ARCHITECT immunoassay (Abbott Laboratories, Abbott Park, IL) utilizing the 2-step chemiluminescent microparticle immunoassay (CMIA) format. The gal-3 immunoassay has a measuring interval of 4.0 to 114.0 ng/mL. The intra- and interassay CV ranged from 0.9% to 6.7% and 1.4% to 8.6%, respectively. GDF-15 GDF-15 was measured using a prototype ARCHITECT immunoassay (Abbott Laboratories, Abbott Park, IL) utilizing the 2-step chemiluminescent microparticle immunoassay (CMIA) format. The GDF-15 immunoassay has a measuring interval of 10 to 25,000 pg/mL. The intra- and interassay CV ranged from 1.6% to 4.4% and 1.8% to 4.5%, respectively.
