河北医科大学第二医院傅向华、李伟等研究提示,预防性冠脉内应用山莨菪碱可减少急性下壁心肌梗死(AIMI)患者PCI后无复流的发生,改善心肌灌注。


河北医科大学第二医院傅向华、李伟等研究提示,预防性冠脉内应用山莨菪碱可减少急性下壁心肌梗死(AIMI)患者PCI后无复流的发生,改善心肌灌注。
 
接受直接PCI 治疗的AIMI 患者中,相当一部分患者表现为血压低、心率慢,导致冠脉灌注压低,后续的心肌灌注不良。
 
本研究中,研究者在直接PCI 治疗的AIMI 患者在梗死相关动脉(IRA)开通前冠脉内给予山莨菪碱1 500 μg/3 ml,对照组注入生理盐水。
 
PCI 后,这些患者的TIMI 血流3 级及TMPG 3 级的患者比例均显著高于对照组。
 
而且心电图ST 段明显回落,ST 段抬高振幅总和(ΣSTE)从(10.0±4.2) mm 下降至(5.8±1.7)mm,两组完全STR 的比例明显不同(69.4% vs 50.7%)。
 
本研究发现, 再灌注后,山莨菪碱组有4 例(5.6%)患者发生再灌注性过缓心律失常;而对照组有42 例(59.2%)患者发生再灌注性过缓心律失常。
 
多变量Logistic 回归分析显示:冠脉舒张压降低及心率减慢是不完全STR 的独立危险因素,冠脉内应用山莨菪碱为完全STR 的保护性因素。
 
研究纳入发病12 h 内接受直接PCI的AIMI 患者。山莨菪碱组72例,对照组71例。
