| 目的 探讨实时三平面应变率成像评价正常人左心房功能的可行性。方法 选择健康志愿者40名,应用实时三平面容积成像测算左心房扩展指数、被动排空分数和主动排空分数,应用实时三平面应变率成像测算收缩期、舒张早期和心房收缩期左心房心肌平均峰值应变率(MSR)。结果 收缩期MSR与扩展指数呈正相关(r=0.61, P<0.01),舒张早期MSR与被动排空分数呈负相关(r=－0.67, P<0.01),心房收缩期MSR与主动排空分数呈负相关(r=－0.78, P<0.01)。结论 实时三平面应变率成像能够定量评价正常人左心房局部心肌功能。 |

| Objective To evaluate the feasibility of real-time triplane strain rate imaging for the quantitative assessment of left atrial function in normal subjects. Methods Totally 40 healthy volunteers were enrolled. Left atrial expansion index (LAEI), left atrial passive emptying fraction (LAPEF) and left atrial active emptying fraction (LAAEF) were measured using real-time triplane volume analysis. Mean systolic peak strain rate (MSRs), mean early diastolic peak strain rate (MSRe) and mean late diastolic peak strain rate (MSRa) were measured using real-time triplane strain rate imaging. The results were compared respectively. Results MSRs correlated positively with LAEI (r=0.61, P<0.01). MSRe correlated inversely with LAPEF (r=－0.67, P<0.01), so did MSRa with LAAEF (r=－0.78, P<0.01). Conclusion Real-time triplane strain rate imaging is feasible for the quantification of left atrial function in normal subjects. |
