| 摘 要： | 目的:应用斑点追踪成像技术（STI）测量正常人及慢性心力衰竭患者(HF)左室短轴各节段二维应变，探讨STI技术评价HF患者左室功能的临床价值。方法: 采集HF患者及对照组左室短轴(二尖瓣、乳头肌、心尖水平)二维高帧频图像，测量各节段的收缩期径向应变（Rs）、环向应变（Cs）。结果: 对照组Rs在同一水平各节段间差异无统计学意义，乳头肌水平显著高于心尖水平，Cs在同一水平各节段间差异有统计学意义（P<0.05）。HF组各短轴水平整体Rs、Cs及各节段的Rs、Cs均显著低于对照组（P<0.01）。结论: HF患者左室各短轴水平及各节段收缩期径向及环向应变均明显低于正常人，提示其左室短轴收缩功能明显受损。

| Abstract: | AIM:To evaluate the clinical value of speckle tracking imaging in the measurement of left ventricular short-axis views regional strain in patients with heart failure.METHODS:High-frame rate two-dimensional images were recorded from the left ventricular short-axis views and regional radial strain and circumferential strain were measured in the left ventricular short-axis views from heart failure patients and from control group.RESULTS:In the control group no significant difference was observed in regional ra... |
