Weighted co-expression network analysis produced metabolic indices that were regressed against all-cause mortality and composite outcomes (death or readmission) using multivariable proportional hazards and win-ratio models. In HFpEF, metabolic indices of nitric oxide signalling and glycaemic control (netNO-pEF) and purine metabolism (netPurine-pEF) predicted outcomes. In HFrEF, indices of acylcarnitine (netACa-rEF) and amino acids (netAA-rEF) predicted outcomes. Every 20% higher netNO-pEF was associated with adjusted hazard ratios (HR20%higher) of 0.64 [95% CI 0.49\u20130.84] in PEOPLE-HFpEF and 0.40 [0.20\u20130.83] in SHOP-HFpEF; HR20%higher for netPurine-pEF were 1.71 [1.30\u20132.24] in PEOPLE-HFpEF and 1.96 [1.08\u20133.55] in SHOP-HFpEF; HR20%higher for netACa-rEF were 1.48 [1.23\u20131.79] in PEOPLE-HFrEF and 1.39 [1.15\u20131.68] in SHOP-HFrEF; HR20%higher for netAA-rEF were 0.75 [0.62\u20130.91] in PEOPLE-HFrEF and 0.51 [0.39\u20130.67] in SHOP-HFrEF. Adjusted inverse win-ratios were concordant: 1\/WR20%higher for netACa-rEF were 1.40 [1.19\u20131.64] in PEOPLE-HFrEF and 1.17 [1.02\u20131.34] in SHOP-HFrEF; 1\/WR20%higher for netNO-pEF were 0.74 [0.54\u20131.00] in PEOPLE-HFrEF and 0.55 [0.33\u20130.89] in SHOP-HFrEF. netNO-pEF was negatively associated with body surface area among HFpEF with concomitant hypertension and diabetes, but only in SHOP-HFpEF. Adding orotic acid, a constituent metabolite of netNO-pEF, to a base model containing five risk indices (MAGGIC score, NT-proBNP, hsTnT, GDF15, and E\/e\u2032 ratio) incrementally improved 2-year mortality prediction (AUROC: 0.82\u21920.83 in PEOPLE; 0.74\u21920.79 in SHOP).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
