CLIN CHEM:接受诊断性冠状动脉造影的患者中内皮素1水平如何?

2018-11-02 MedSci MedSci原创

内皮素-1(ET-1)是由血管内皮细胞产生的血管收缩剂,在冠状动脉疾病(CAD)和心力衰竭(HF)的发展中起到一定作用。在一组1084名冠状动脉造影患者中,我们研究了ET-1浓度与流行CAD之间的横断面关联,以及ET-1对未来心血管事件预测的价值。 研究人员评估ET-1与CAD及严重程度之间的关联。患者的中位随访时间为4年,其结果包括HF,心肌梗死(MI),心血管死亡率和全因死亡率。

内皮素-1ET-1)是由血管内皮细胞产生的血管收缩剂,在冠状动脉疾病(CAD)和心力衰竭(HF)的发展中起到一定作用。在一组1084名冠状动脉造影患者中,我们研究了ET-1浓度与流行CAD之间的横断面关联,以及ET-1对未来心血管事件预测的价值。

研究人员评估ET-1CAD及严重程度之间的关联。患者的中位随访时间为4年,其结果包括HF心肌梗死MI),心血管死亡率和全因死亡率。

结果显示,ET-1的中位浓度为2.57 ng / LET-1浓度高于中位数的患者更可能有更高风险的临床特征。在那些没有出现MI的患者中,ET-1浓度与CADCAD严重程度无关。在校正后的Cox比例风险分析中,对数转换的ET-1浓度可预测事故HF [风险比(HR=每增加log-SD 1.51; 95CI1.06-2.15; P = 0.02]和全因死亡率(log = SD每增加HR = 1.61; 95CI1.03-2.53; P = 0.04)。高于中位数的ET-1浓度与短期发生HFMI,心血管死亡率,全因死亡率以及HF / MI /心血管事件死亡率(所有对数排名)相关。P <0.001)。

结果表明,尽管在流行病学,ET-1CAD存在关联,但研究发现在冠状动脉造影的高危人群中,生物活性ET-1与普遍存在的冠状动脉粥样硬化之间没有横断面关联性。ET-1浓度的增加可独立预测HF和死亡事件,并与更近期的心血管事件有关。

Lancet:对于冠状动脉造影和PCI辐射暴露的担心是多余的

经桡动脉心脏导管插入术比传统的经股动脉有较低的出血和血管并发症。然而,经桡动脉心脏导管插入术潜在增加的辐射暴露是这种方法的一个可能的缺点。辐射显著增加的经桡动脉心脏导管插入术是否超过它的好处是不清楚的。因此,该研究的目的是比较对于冠状动脉造影和经皮冠状动脉介入治疗(PCI)经桡动脉和经股动脉之间的辐射影响。
