摘要
目的:保留射血分数的心力衰竭(HFpEF)具有很高的发病率和死亡率,对诊断、预后和治疗提出了重大挑战。目前,HFpEF患者预后的预测指标有限。循环氧化的多不饱和脂肪酸酰基脂,或氧脂类,已知可以引发和解决心血管疾病中的炎症。然而,它们预测HFpEF死亡率的能力尚未得到证实。我们假设一组氧脂素可以预测和分层HFpEF患者的死亡风险。方法和结果:在同一医院对90例HFpEF患者进行右心导管置管时采集静脉和动脉血样。患者随访5年以确定发病率和死亡率。我们使用液相色谱-质谱法测量了所有研究参与者的143个动脉和143个静脉氧脂素。火山图用于可视化幸存和死亡群体之间的氧化脂质差异。采用受试者操作特征(ROC)曲线确定最佳生物标志物切点,并采用Kaplan-Meier (KM)曲线评估最显著的氧化脂素与死亡率之间的关系。HFpEF患者的5年死亡率在基线时年龄增加,体重指数下降,舒张压下降,肾功能恶化。他们也有更严重的肺动脉高压(PH)和右心功能障碍。火山图分析显示,动脉氧脂素15-酮前列腺素F2a (PGF2a)与5年死亡率显著相关。ROC曲线分析确定了15-酮PGF2a的最佳切割点,动脉15-酮PGF2a升高的参与者在KM曲线上的5年死亡率显着增加。多变量调整分析发现15-酮PGF2a是5年死亡率的重要预测因子(OR 1.82; CI 1.03, 3.5)。结论:在该HFpEF患者队列中,动脉15-酮PGF2a (PGF2a的稳定代谢物)显著预测5年死亡率。
Circulating oxylipins predict mortality in heart failure with preserved ejection fraction.
Aims: Heart failure with preserved ejection fraction (HFpEF) poses significant diagnostic, prognostic and therapeutic challenges, with high morbidity and mortality rates. Currently, there are limited predictors of outcomes in HFpEF patients. Circulating oxidized polyunsaturated fatty acyl lipids, or oxylipins, are known to initiate and resolve inflammation in cardiovascular diseases. However, their ability to predict mortality in HFpEF has not been established. We hypothesize that a panel of oxylipins can predict and stratify mortality risk in HFpEF patients.
Methods and results: Venous and arterial blood samples were collected during right heart catheterization from 90 HFpEF patients at a single institution. Patients were followed for 5 years to determine morbidity and mortality rates. We measured 143 arterial and 143 venous oxylipins in all study participants using liquid chromatography-mass spectrometry. Volcano plots were used to visualize differences in oxylipins between survived and deceased groups. Receiver operator characteristic (ROC) curves were used to determine optimal biomarker cut-points, and the relationship between the most significant oxylipins and mortality was assessed with Kaplan-Meier (KM) curves. HFpEF patients with 5-year mortality had increased age, decreased body mass index, decreased diastolic blood pressure and worse renal function at baseline. They also had more severe pulmonary hypertension (PH) and right heart dysfunction. Volcano plot analysis revealed that arterial oxylipin 15-keto prostaglandin F2a (PGF2a) was significantly associated with 5-year mortality. ROC curve analysis identified an optimal cut-point for 15-keto PGF2a, and participants with elevated arterial 15-keto PGF2a had significantly increased 5-year mortality on KM curves. Multivariable adjusted analysis identified 15-keto PGF2a as a significant predictor of 5-year mortality (OR 1.82; CI 1.03, 3.5).
Conclusions: In this cohort of patients with HFpEF, arterial 15-keto PGF2a, a stable metabolite of PGF2a, significantly predicted 5-year mortality.
期刊介绍:
ESC Heart Failure is the open access journal of the Heart Failure Association of the European Society of Cardiology dedicated to the advancement of knowledge in the field of heart failure. The journal aims to improve the understanding, prevention, investigation and treatment of heart failure. Molecular and cellular biology, pathology, physiology, electrophysiology, pharmacology, as well as the clinical, social and population sciences all form part of the discipline that is heart failure. Accordingly, submission of manuscripts on basic, translational, clinical and population sciences is invited. Original contributions on nursing, care of the elderly, primary care, health economics and other specialist fields related to heart failure are also welcome, as are case reports that highlight interesting aspects of heart failure care and treatment.
