摘要 急性心肌梗死(AMI)是心血管疾病中最危急类型之一,以持续剧烈的胸骨后疼痛为主,可诱发心律失常、心力衰竭及休克,致残致死率较高[1].经皮冠状动脉介入手术(PCI)可及早开通梗死血管,挽救频死心肌,研究证实,可使AMI患者病死风险降低25%,已成为AMI治疗重要手段[2].PCI术后行左心室整体及局部收缩功能检测对疗效及预后评估具有重要指导意义.三维斑点追踪成像技术(3D-STI)是在二维斑点追踪成像技术(2D-STI)及三维超声心动图基础上发展而得到,其克服了2D-STI的局限性,能够追踪心肌斑点在三维空间内的实时运动,评估心肌复杂形变,是一种准确定量判定左心室功能的新技术[3].为探究3D-STI技术对左心室收缩功能的评估价值,本研究选取72例行PCI手术治疗的ST段抬高型AMI患者,以期能为临床研究提供参考依据,现报告如下.
