摘要 目的探讨心肌血流储备分数(FFRmyo)在冠状动脉临界病变(狭窄50%~70%)介入治疗中的指导价值。方法将40例经冠状动脉造影显示冠状动脉临界病变的冠心病患者随机分为试验组(20例)和对照组(20例),观察两组患者术中支架植入数目、造影剂用量及手术时间,并随访一年,观察两组患者主要不良心脏事件(MACE,包括心源性死亡、心肌梗死、再次血运重建)和心绞痛情况。结果试验组支架植入数量、造影剂用量、手术时间明显少于对照组[(1.6±0.8)个vs.(2.1±0.7)个、(196±88)mlvs.(267±102)ml、(54±21)minvs.(65±23)min](P均<0.05);随访一年MACE事件及心绞痛情况无显著性差异(P>0.05)。结论对于冠状动脉临界病变,通过测定FFRmyo值,可评价狭窄冠状动脉与心肌缺血之间的关系,对冠状动脉介入治疗具有重要的指导意义。
