Circ-Heart Fail:射血分数降低的心力衰竭患者皮肤间质改变

2018-07-15 xing.T MedSci原创

由此可见,与健康受试者相比,HFrEF患者的间质糖胺聚糖浓度显著增加,并与组织水含量和容量超负荷的临床体征相关。更好地了解间质腔室可以改善HF中容量超负荷的治疗。

间质糖胺聚糖的网络有助于调节水和电解质的稳态。皮下间质改变与射血分数降低的心力衰竭(HFrEF)患者水肿发生之间的关系尚不清楚。近日,心血管领域权威杂志Circ-Heart Fail上发表了一篇研究文章,研究人员假设在HFrEF患者中(1)间质糖胺聚糖密度增加,(2)间质糖胺聚糖网络的变化与间质液积聚有关,(3)间质糖胺聚糖网络与肾素-血管紧张素-醛固酮系统之间存在联系。

在健康受试者(n=18)和HFrEF患者(n=29)中获得两次皮肤穿刺活检样本。研究人员进行了阿尔新蓝染色和血管紧张素II1型受体的免疫染色。在获得组织水含量后,对总的间质糖胺聚糖(糖醛酸)和硫酸化糖胺聚糖进行定量。同时,获得受试者静脉血样,进行临床检查和超声心动图。

与健康受试者相比,HFrEF患者的间质糖胺聚糖含量显著增高(糖醛酸:13.0±4.2 vs. 9.6±1.6μg/mg; P=0.002;硫酸化糖胺聚糖:14.1 [11.7-18.1] vs. 10.0 [9.1- 10.8] μg/mg; P<0.001)。糖醛酸和硫酸化糖胺聚糖密度与组织水含量和外周水肿密切相关(糖醛酸:ρ=0.66; P<0.0001和硫酸化糖胺聚糖:τ=0.58; P<0.0001)。尽管使用血管紧张素转换酶抑制剂/血管紧张素受体阻滞剂与HFrEF患者显著较低水平的间质糖胺聚糖相关,但在真皮细胞上发现了血管紧张素II1型受体的表达。

由此可见,与健康受试者相比,HFrEF患者的间质糖胺聚糖浓度显著增加,并与组织水含量和容量超负荷的临床体征相关。更好地了解间质腔室可以改善HF中容量超负荷的治疗。

Circulation:女性更易罹患射血分数保留型心力衰竭

研究者评估了性别对心脏结构与功能、全身循环与肺循环的决定因素的影响,以及可能影响女性对HFpEF易感性的心外因素和共病因素。研究人员认为,处于怀孕、先兆子痫和缺铁状态的女性,更容易受到上述因素的影响。研究者还讨论了目前存在的争议和认识的不足,以及已知性别差异特异性诊断标准、风险分层模型和靶向治疗的临床意义。

Clin Chem:新的脂质生物标志物板用于检测低射血分数性心力衰

该研究在于寻找一种新的代谢组学生物标志物用于诊断射血分数降低性心力衰竭(HFrEF). 研究纳入887名试验参与者,其中缺血性HFrEF患者(ICMP)为257名,非缺血性HFr EF患者(NICMP)为269名,健康对照者为327名,肺动脉疾病患者为34名。先后进行单中心识别研究(N=238)和多中心验证研究(N=649).对单中心研究中的血浆样本进行代谢谱分析,识别可作为HFrEF潜在

JAHA:HFpEF与HFREF患者住院期间肾功能恶化的预测和预后价值!

由此可见,在急性心力衰竭患者中,WRF是HFpEF和HFrEF患者不良住院事件和随访不良结局的独立预测因素。

JAHA:胸腺肽β4在射血分数正常的心力衰竭患者中升高!

由此可见,女性HFpEF患者血浆中TB4水平升高,并且可以提供预后信息。因为在心肌损伤的动物实验中TB4能保持EF,因此,女性心脏病患者中内源性循环TB4与X染色体生物学和分化结局值得进一步研究。

EUR HEART J :慢性心力衰竭中功能性二尖瓣返流的预后影响

目前,研究人员正在努力减少慢性心力衰竭患者的功能性二尖瓣返流(FMR),以期改善预后。近日,在医学权威杂志EUR HEART J上面发表了一篇研究文章,研究人员旨在评估心力衰竭患者采用最佳药物治疗(OMT)以及HFrEF的各种条件下的FMR的预后影响。研究人员进一步研究了心脏衰竭的表现型。

JAHA:胶原标志物对射血分数降低和正常的心力衰竭预测价值如何?

由此可见,高水平的循环胶原生物标志物ICTP和PIIINP似乎与HFpEF发生有关,但与HFrEF无关。
