    美国心脏协会科学年会展出三项研究:卒中后及2型糖尿病人群降血压治疗在研究与实践中的挑战

    三项研究周六在美国心脏协会芝加哥科学年会上展出,探讨卒中及2型糖尿病人群的降压策略。其中一项小型但人群多样的试验测试卒中后使用一种常用利尿剂,另一项研究强化治疗以达成低于标准的卒中后血压目标,第三项探索2型糖尿病患者更积极的降压。文中指出高血压升高这些人群严重心血管事件风险、治疗需跨专科协作,新闻稿未给出具体结果数据。

    DAPT-SHOCK-AMI 随机双盲试验:急性心肌梗死合并心源性休克患者中 Cangrelor 与碾碎替格瑞洛比较,30 天主要终点非劣效未成立

    DAPT-SHOCK-AMI 随机双盲试验在急性心肌梗死合并心源性休克(AMI-CS)患者中比较 Cangrelor 与碾碎替格瑞洛两种 P2Y12 抑制策略。结果显示,主要 PCI 结束时 Cangrelor 达到有效血小板抑制的比例更高,但 30 天临床主要终点未证实其相对碾碎替格瑞洛的非劣效。作者称这是该人群首个此类随机试验,结果可为未来 P2Y12 抑制策略研究提供依据。

    肺栓塞患者血小板脂质组改变与血小板分化为不同亚群相关:合并右心室受累者的观察性研究

    一项纳入48例急性肺栓塞(PE)患者的观察性研究,通过CT肺动脉造影和超声心动图区分有无右心室(RV)受累,采用流式细胞术和HPLC-ESI-QTOF-MS/MS分析血小板亚群与脂质组。合并RV受累者聚集型血小板水平更高(P=0.021)、促凝型血小板更低(P=0.033),胆固醇酯、甘油三酯和脂肪酸显著上调,且脂质与两种血小板亚群水平相关。结果提示血小板脂质组重塑可能与PE中血小板表型分化有关。
