    我国河北医科大学附属第二医院研究人员在2012年世界心脏病学大会上报告的一项研究显示:ST段抬高型心肌梗死(STEMI)病人直接经皮冠状动脉介入(PCI)术前静脉输注山莨菪碱,有可能预防造影剂肾病(CIN)的发生。
 
    CIN是PCI术后最严重的并发症之一。接受直接PCI的急性心肌梗死病人发生CIN的风险较大。山莨菪碱是从中草药中提取的一种生物碱,广泛用于治疗感染性休克、急性肾小球肾炎和糖尿病性肾病,临床证明山莨菪碱对肾功能有保护作用。该研究旨在研究山莨菪碱对行直接PCI的STEMI病人是否有CIN预防作用。
 
    研究人员将连续行直接PCI的病人随机分为2组:山莨菪碱组(ANI组,在PCI前30分钟内静脉输注山莨菪碱(每分钟3-4μg/kg);对照组(CON组)静脉输注相同体积的等张盐水(0.9%)。PCI术后全部病人静脉输注等张盐水12小时。病人住院时,PCI术后24、48和72小时测量血清肌酐(SCr)浓度。
共126例病人完成研究,其中ANI组60例,CON组66例。PCI术后2组病人的SCr浓度显著升高,术后48小时达峰值(2组P值均《0.0001),然后开始下降。术后72小时ANI组病人的SCr浓度显著降低(P<0.0001),恢复至基线水平(P>0.05)。术后72小时CON组病人的SCr浓度也显著降低(P<0.0001),但仍高于基线水平(P<0.0001)。PCI术后48和72小时ANI 组病人的SCr浓度较CON组病人低得多(2个P值均<0.05)。PCI术后估计肾小球滤过率(eGFR)显著降低,48小时降至最低值,然后开始上升。术后72小时ANI组病人的 eGFR显著升高(P<0.0001),接近基线水平(P>0.05);CON组病人的eGFR也显著升高(P<0.0001),但在术后72小时时没有恢复到基线水平(P<0.0001)。PCI术后24、48和72小时ANI组病人的eGFR较CON组病人高(全部P<0.05)。PCI术后72小时内,ANI组病人的CIN发生率较CON组低(全部 P<0.05) 。
 
该摘要于4月15日在线发表于《循环》(Circulation)2012世界心脏病学大会(WCC)口头报告,编号0046。
