Many patients with heart failure with preserved ejection fraction (HFpEF) are women. Exploring mechanisms underlying the sex differences may improve our understanding of the pathophysiology of HFpEF. Studies focusing on sex differences in circulating proteins in HFpEF patients are scarce. A total of 415 proteins were analyzed in 392 HFpEF patients included in The Metabolic Road to Diastolic Heart Failure: Diastolic Heart Failure study (MEDIA-DHF). Sex differences in these proteins were assessed using adjusted logistic regression analyses. The associations between candidate proteins and cardiovascular (CV) death or CV hospitalization (with sex interaction) were assessed using Cox regression models. We found 9 proteins to be differentially expressed between female and male patients. Women expressed more LPL and PLIN1, which are markers of lipid metabolism; more LHB, IGFBP3, and IL1RL2 as markers of transcriptional regulation; and more Ep-CAM as marker of hemostasis. Women expressed less MMP-3, which is a marker associated with extracellular matrix organization; less NRP1, which is associated with developmental processes; and less ACE2, which is related to metabolism. Sex was not associated with the study outcomes (adj. HR 1.48, 95% CI 0.83–2.63), p = 0.18. In chronic HFpEF, assessing sex differences in a wide range of circulating proteins led to the identification of 9 proteins that were differentially expressed between female and male patients. These findings may help further investigations into potential pathophysiological processes contributing to HFpEF.

射血分数保留的心力衰竭循环蛋白的性别差异。

许多射血分数保留的心力衰竭 (HFpEF) 患者是女性。探索性别差异背后的机制可能会提高我们对 HFpEF 病理生理学的理解。关注 HFpEF 患者循环蛋白性别差异的研究很少。在舒张性心力衰竭的代谢途径:舒张性心力衰竭研究 (MEDIA-DHF) 中包括的 392 名 HFpEF 患者中,总共分析了 415 种蛋白质。使用调整后的逻辑回归分析评估这些蛋白质的性别差异。使用 Cox 回归模型评估候选蛋白质与心血管 (CV) 死亡或 CV 住院(具有性别相互作用)之间的关联。我们发现 9 种蛋白质在女性和男性患者之间差异表达。女性表达更多的LPL和PLIN1,它们是脂质代谢的标志物;更多 LHB、IGFBP3 和 IL1RL2 作为转录调控的标志物;和更多 Ep-CAM 作为止血标志物。女性表达较少的 MMP-3,这是一种与细胞外基质组织相关的标志物;与发育过程相关的 NRP1 减少;和代谢相关的ACE2少。性别与研究结果无关(调整 HR 1.48,95% CI 0.83–2.63),p = 0.18。在慢性 HFpEF 中,评估各种循环蛋白质的性别差异导致鉴定出女性和男性患者之间差异表达的 9 种蛋白质。这些发现可能有助于进一步调查导致 HFpEF 的潜在病理生理过程。和更多 Ep-CAM 作为止血标志物。女性表达较少的 MMP-3,这是一种与细胞外基质组织相关的标志物;与发育过程相关的 NRP1 减少;和代谢相关的ACE2少。性别与研究结果无关(调整 HR 1.48,95% CI 0.83–2.63),p = 0.18。在慢性 HFpEF 中,评估各种循环蛋白质的性别差异导致鉴定出女性和男性患者之间差异表达的 9 种蛋白质。这些发现可能有助于进一步调查导致 HFpEF 的潜在病理生理过程。和更多 Ep-CAM 作为止血标志物。女性表达较少的 MMP-3,这是一种与细胞外基质组织相关的标志物;与发育过程相关的 NRP1 减少;和代谢相关的ACE2少。性别与研究结果无关(调整 HR 1.48,95% CI 0.83–2.63),p = 0.18。在慢性 HFpEF 中,评估各种循环蛋白质的性别差异导致鉴定出女性和男性患者之间差异表达的 9 种蛋白质。这些发现可能有助于进一步调查导致 HFpEF 的潜在病理生理过程。这与新陈代谢有关。性别与研究结果无关(调整 HR 1.48,95% CI 0.83–2.63),p = 0.18。在慢性 HFpEF 中,评估各种循环蛋白质的性别差异导致鉴定出女性和男性患者之间差异表达的 9 种蛋白质。这些发现可能有助于进一步调查导致 HFpEF 的潜在病理生理过程。这与新陈代谢有关。性别与研究结果无关(调整 HR 1.48,95% CI 0.83–2.63),p = 0.18。在慢性 HFpEF 中,评估各种循环蛋白质的性别差异导致鉴定出女性和男性患者之间差异表达的 9 种蛋白质。这些发现可能有助于进一步调查导致 HFpEF 的潜在病理生理过程。
