摘要 目的探讨二维斑点追踪(2D-STI)技术评价冠心病(CHD)患者经皮冠状动脉介入(PCI)治疗后左心室局部及整体功能变化的价值。方法 67例CHD患者和34例对照者,CHD患者根据是否有心肌梗死分为心绞痛组(A组,36例)和心肌梗死组(B组,31例),分别于PCI术前、术后3个月行超声心动图检查,应用2D-STI获得左室6个壁基底段、中间段、心尖段的收缩期纵向峰值应变值(SLs)、整体纵向峰值应变(GSL)、舒张早期纵向峰值应变率(SrLe)。结果 A组和B组PCI术前心肌缺血节段SLs、SrLe及GSL较对照组低(P<0.05);与PCI治疗前比较,A、B两组PCI治疗后3个月相应节段的SLs、SrLe及GSL明显提高(P<0.05),且A组较B组变化明显(P<0.05)。结论 PCI治疗能有效改善CHD患者左室功能。2D-STI技术可定量、客观的评价这一变化,为PCI疗效评定和CHD预后判定提供了一种无创手段。
