| 目的 运用超声三维斑点追踪（3D-STE）技术观察肥厚型心肌病（HCM）患者左心房心肌面积应变变化。方法 对65例HCM患者，包括非梗阻型（HNCM组）35例、梗阻型（HOCM组）30例，以及43名健康志愿者（对照组）分别采集并存储全容积左心室心尖四腔和两腔切面图像；运用3D-STE分析软件进行脱机分析，软件自动将左心房心肌分为16节段，比较各组间左心房16个心肌节段之间峰值面积应变（PAS）和整体面积峰值应变（GAPS）之间的差异。结果 ①与对照组比较，HNCM组、HOCM组左心房各节段PAS、GAPS均显著减低（P均<0.05）。②与HNCM组比较，HOCM组左心房大部分节段PAS增高（P均<0.05）；HOCM组GAPS略高于HNCM组，但差异无统计学意义（P>0.05）。结论 3D-STE技术可反映HCM患者左心房心肌面积应变变化。 |

| Objective To assess changes of left atrial (LA) area strains in patients with hypertrophic cardiomyopathy (HCM) with three-dimensional speckle tracking echocardiography (3D-STE). Methods Sixty-five HCM patients (30 with obstruction, HOCM group, 35 without obstruction at resting, HNCM group) and 43 healthy subjects (control group) were enrolled. Apical full-volume images were acquired in all subjects and then were analyzed by off-line 3D-STE analysis software. The software divided LA into 16 segments automatically, and the peak area strain (PAS), global area peak strain (GAPS) of left atrial were obtained and compared. Results ①Compared with control group, PAS and GAPS of all atrial segments were significantly lower in HNCM group and HOCM group (all P<0.05). ②Compared with HNCM group, PAS within most of LA segments were significantly increased in HOCM group (all P<0.05), while GAPS of LA mildly increased in HOCM group, but no statistical difference was found (P>0.05). Conclusion 3D-STE is a feasible modality to assess LA area strains in patients with HCM. |
