JACC:二尖瓣环分离心律失常综合征

2018-09-29 MedSci MedSci原创

二尖瓣环分离(MAD)会引起二尖瓣脱垂(MVP)和心源性猝死。本研究的目的旨在评估MAD患者的临床特征、二尖瓣形态、MVP情况及室性心律失常情况。本研究最终纳入了116名MAD患者(平均年龄49±15岁,女性占60%)。心悸是最常见的临床症状(71%),严重的心律不齐占14例(12%)。伴心律不齐的MAD患者年龄更小(p = 0.001),射血分数更低(51 ± 5% vs. 57 ± 7%; p

二尖瓣环分离(MAD)会引起二尖瓣脱垂(MVP)和心源性猝死。本研究的目的旨在评估MAD患者的临床特征、二尖瓣形态、MVP情况及室性心律失常情况。

本研究最终纳入了116名MAD患者(平均年龄49±15岁,女性占60%)。心悸是最常见的临床症状(71%),严重的心律不齐占14例(12%)。伴心律不齐的MAD患者年龄更小(p = 0.001),射血分数更低(51 ± 5% vs. 57 ± 7%; p = 0.002),乳头肌纤维化更常见(4 [36%] vs. 6 [9%]; p = 0.03)。另外,MVP在90例患者中较明显,且与室性心律失常无相关性。

研究结果显示,室性心律失常事件在二尖瓣环分离患者中常见,且二尖瓣脱垂与室性心律失常事件无关,提示是二尖瓣环分离本身会引起心律失常。

JAHA:前列腺素受体2在受损心脏修复中起重要作用

前列腺素E2是公认的免疫调节因子,它在组织受损后释放,并参与调控巨噬细胞的活性,然而前列腺素受体2(EP2)调节的巨噬细胞在心脏缺血后的作用尚不清楚。本研究的目的旨在探究EP2在受损心脏中的作用。本研究利用EP2转基因小鼠模型,发现EP2敲除小鼠的心脏在受损后心功能会更差,并且EP2的缺失会改变促炎反应,导致巨噬细胞聚集于受损心肌的缺陷。转录组分析结果显示红系分化调节蛋白1(Erdr1)在EP2敲

JACC:血栓抽吸不能改善高血栓风险STEMI患者预后

常规的血栓抽吸对接受经皮冠脉介入治疗(PCI)的ST段抬高型心梗(STEMI)患者来说并不会改善预后,但对有高血栓风险的该类患者来说是否有益尚不清楚。本研究的目的旨在评估血栓抽吸对伴高血栓风险的STEMI患者是否有益。本研究纳入的是TOTAL临床研究中的STEMI患者,主要终点事件是心源性死亡、心梗、心源性休克和心衰。分析结果显示,1年主要终点事件在接受血栓抽吸的高血栓风险STEMI患者和不接受抽

JACC:透明质酸代谢在急性冠脉综合征的发生中起重要作用

浅表性糜烂或溃疡占急性冠脉综合征(ACS)发表原因至少三分之一,然而其分子机制尚不清楚。本研究的目的旨在评估透明质酸(HA)代谢在ACS中的作用。本研究收集了66例ACS、55例稳定性心绞痛(SA)和45例对照的外周血单核细胞,并对其HYAL2、CD44v1、CD44v4和 CD44v6基因的表达, HYAL2和CD44的蛋白表达量进行了测量。分析结果显示,HYAL2、CD44v1和CD44v6的

JACC:多摄入海产品可降低外周动脉疾病风险

动物脂肪组织的海洋n-3多不饱和脂肪酸(PUFAs)含量被认为是机体长期摄入海产品的生物标志物。本研究的目的旨在评估机体脂肪组织中PUFAs的含量与外周动脉疾病(PAD)的关系。本研究纳入了丹麦饮食、癌症和健康研究队列中的对象,脂肪组织是从所有研究对象的臀部获取,经过平均13.5年时间的随访,共有870例对象出现PAD。分析结果显示,二十碳五稀酸(EPA)含量越高,PAD的发生风险越低([HR]:
