JACC:稳定性冠心病患者应不应该接受介入治疗?

2018-08-23 MedSci MedSci原创

最近,经皮冠脉介入治疗(PCI)的治疗效益在稳定性冠心病(SCD)患者中存在争议。本研究的目的旨在评估PCI对SCD患者锻炼后的冠脉循环、微循环和全身血液动力学的影响。本研究对21例SCD伴单支冠脉狭窄的患者(平均年龄60.3 ± 8.4岁)进行了心导管术。PCI术前,患者在仰卧测力计上运动直至心绞痛或筋疲力尽,在运动的同时对狭窄的冠脉血流进行测量,PCI术后同样做此操作,并比较术前和术后患者的生

最近,经皮冠脉介入治疗(PCI)的治疗效益在稳定性冠心病(SCD)患者中存在争议。本研究的目的旨在评估PCI对SCD患者锻炼后的冠脉循环、微循环和全身血液动力学的影响。

本研究对21例SCD伴单支冠脉狭窄的患者(平均年龄60.3 ± 8.4岁)进行了心导管术。PCI术前,患者在仰卧测力计上运动直至心绞痛或筋疲力尽,在运动的同时对狭窄的冠脉血流进行测量,PCI术后同样做此操作,并比较术前和术后患者的生理学指标、临床症状和运动表现。通过分数流量储备值、瞬时无波比值和冠状动脉血流储备值,发现PCI可以减轻患者的心绞痛。PCI还可以峰值运动状态下平均冠状动脉血流速度(p < 0.0001)、冠脉灌注压(p < 0.0001)、收缩压(p = 0.01)和心肌工作量(p < 0.01)。这些术后即刻的改变来自冠脉狭窄的解除。另外,PCI还可以提高运动时间和减轻心绞痛的症状。

研究结果显示,对于伴有单支冠脉狭窄的稳定性冠心病患者,PCI可以明显改善运动后的客观生理反应。

巨噬细胞在心血管疾病的病理发生过程中起到重要作用。本研究的目的旨在探究GATA3阳性巨噬细胞在心梗后调节心脏功能方面的作用。本研究的小鼠模型为骨髓特异性敲除GATA3小鼠(mGATA3KO),心梗建模后,通过超声心动图对其进行心功能评估。结果发现,急性心梗建模后,GATA3阳性巨噬细胞在梗死区域快速聚集,GATA3阳性巨噬细胞的减少可以明显提高心梗后的心脏功能,这种心功能的改善与mGATA3KO小

Circulation:他汀类药物降低甘油三酯脂蛋白胆固醇的同时亦可降低心血管疾病风险

孟德尔随机数据表明,终身高甘油三酯脂蛋白胆固醇(TRL-C)的遗传决定因素与心血管疾病息息相关,因此可能是潜在的治疗靶点。在服用他汀类药物的患者中,TRL-C与心血管风险的相关性尚不明确。现研究人员对TRL-C和心血管风险之间的关系以及这种风险在他汀类药物治疗的患者中是否会发生改变进行评估。本试验招募冠心病和低密度脂蛋白胆固醇(LDL-C)水平在130-25-mg/dL的患者,进行8周的磨合期,予

Circulation:心血管疾病患者的癌症风险较高?未必!

在社区观察性研究中,有证据显示,心血管疾病与较高的癌症发病率有关。2013年,Hasin等人的研究表明,心力衰竭和后续确诊癌症存在联系。这些发现在对心肌梗死人群的前瞻性队列研究中得到重现,丹麦的大规模心力衰竭队列研究中也观察到类似结果。然而,值得注意的是,这些流行病学研究并未区分射血分数保留型心力衰竭与射血分数降低型心力衰竭对这种相关性的影响差异。
