目的 研究MRI与超声对高血压伴 心室肥厚患者左心室功能的检测结果准 确性并评估两种检查方法临床应用价值。 方法 将92例高血压患者根据左室心肌质 量指数（LVMI）分为高血压组和LVH组， 同时另选我院同期健康体检者50例为对照 组，对3组研究对象分别进行B超和CMR检 查，比较两种检查方法所测心功能指标 差异并采用Bland-Altman图分析其一致 性。结果 B超和MRI测量结果显示，对照 组、高血压组和LVH组LVMI呈上升趋势， 各组间差异有统计学意义（P<0.05）， 且各组B超测量结果均低于CMR，差异有 统计学意义（P<0.05）；B超和MRI所测 高血压组PER及TPER均高于对照组，LVH 组LVEDV、LVESV、SV、PER及TPER均高于 对照组和高血压组，差异有统计学意义 （P<0.05），且B超所测LVEDV、SV、PER 低于CMR，TPER高于CMR，差异有统计学意 义（P<0.05）；Bland-Altman图分析结果 显示，B超与CMR对左室心功能指标测量结 果均值差范围较大，其中B超对LVEDV、 LVESV、SV、EF及PER测量结果偏低，对 TPER测量结果偏高，但两种检查方法所测 LVEDV、LVESV、PER及TPER一致性较好。 结论 B超对高血压伴LVH患者心功能指标 检测结果准确性较MRI偏低，两种检查方 法测量结果差异较大，但一致性良好。

Objective To study the detection accuracy of MRI and ultrasound on left ventricular function in patients with hypertension complicated with ventricular hypertrophy and evaluate the clinical citation value of the two methods. Methods A total of 92 cases of patients with hypertension were divided into hypertension group and LVH group according to left ventricular mass index (LVMI). At the same time, another 50 healthy examiners in our hospital were selected as control group, and the three groups were given B-ultrasound and CMR examination. The cardiac function indicators measured by the two examination methods were compared, and the consistency was analyzed by Bland-Altman diagram. Results B-ultrasound and MRI showed that the LVMI in control group, hypertension group and LVH group showed an upward trend (P<0.05), and the B-ultrasound measurement results of each group were lower than CMR (P<0.05). The PER and TPER in hypertension group measured by B-ultrasound and MRI were higher than those in control group, and the LVEDV, LVESV, SV, PER and TPER in LVH group were higher than those in control group and hypertension group (P<0.05), and the LVEDV, SV and PER measured by B-ultrasound were lower than CMR while the TPER was higher than CMR (P<0.05). Bland-Altman diagram analysis showed that the mean value difference of B-ultrasound and CMR was large in the measurement of left ventricular cardiac function indexes, and the measurement results of B-ultrasound were low on LVEDV, LVESV, SV, EF and PER while the measurement result of TPER were high, but the two methods had good consistency in LVEDV, LVESV, PER and TPER. Conclusion The accuracy of B-ultrasound in cardiac function indexes of patients with hypertension and LVH is lower than that of MRI. The measurement results of the two methods are quite different, but the consistency is good.
