| 目的 探讨三维斑点追踪成像（3D-STI）技术评价蒽环类药物对弥漫大B细胞淋巴瘤（DLBCL）患者早期左心室功能损害的价值。方法 选取2014年12月至2016年10月安徽医科大学第一附属医院行蒽环类药物化疗的DLBCL患者28例，分别于化疗前及化疗2、4、6个周期（即累计剂量达100、200、300 mg/m2）后24~48 h内行二维超声心动图及3D-STI检查，获取常规二维超声心动图数值及左心室整体面积应变（GAS）、整体纵向应变（GLS）、整体圆周应变（GCS）、整体径向应变（GRS），并进行统计学分析。结果 GAS、GLS在化疗4个周期[（-28.66±2.67）%，（-16.49±1.94）%]及6个周期[（-25.14±2.73）%，（-15.12±1.97）%]时，与化疗前[（-34.86±2.90）%，（-18.36±2.32）%]及化疗2个周期[（-34.05±2.09）%，（-17.75±1.91）%]时比较显著降低，差异有统计学意义（P<0.05）。Pearson相关分析显示，GAS与多柔比星累计剂量呈负相关（r=-0.815，P<0.05）。整个化疗进程中，GCS、GRS无明显变化。结论 GAS对DLBCL患者蒽环类药物化疗后出现早期左心室功损害的敏感性较高。3D-STI技术可以发现早期蒽环类药物所致的心脏毒性。 |

| Objective To explore the value of three-dimensional speckle tracking imaging (3D-STI) technology in evaluating the left ventricular myocardial dysfunction in patients with diffuse large B- cell lymphoma after receiving anthracyclines.Methods Conventional echocardiography and 3D-STI parameters were measured from 28 patients with DLBCL before chemotherapy,and during 24-48 hours after 2(100 mg/m2), 4(200 mg/m2) and 6(300 mg/m2) chemotherapy cycles,global area strain(GAS),global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS)were obtained for evaluation and analysis.Results Compared with before chemotherapy and 2 chemotherapy cycles, GAS and GLS decreased statistically after 4 and 6 chemotherapy cycles. Moreover,Pearson correlation analysis showed GAS was significantly associated with cumulative anthracycline dose (r=-0.834,P<0.05).However, the variations on GSC and GRS showed no significant degradation during the whole chemotherapy.Conclusion GAS shows a high sensitivityto detect subclinical left ventricular dysfunction in patients with DLBCL who undertake anthracycline therapy. 3D-STI can be used for an early exploration of the cardiotoxicity of anthracycline. |
