摘　　要：目的探究常规超声(2DE)联合心脏声学造影(LVO)对心肌致密化不全(NVM)的诊断价值。方法选取2017年1月—2021年6月于该院经常规二维超声心动图(2DE)诊断为疑似LVNC的患者为研究对象,共43例,所有患者均进行左心声学造影(LVO)检查,以Jenni等推荐的超声诊断标准作为标准,依据AHA16节段分析法,于收缩末期、舒张末期,对比评估2DE、LVO、2DE联合LVO对心肌节段的显示率、NC节段发现率、NC/C值及左心室射血分数(LVEF),综合评价2DE联合LVO对NVM的诊断价值。结果43例2DE检查疑似NVM患者中,32例符合Jenni诊断标准确诊。2DE联合LVO检查在舒张末期、收缩末期的心肌节段清晰显示率均较单一2DE检查、单一LVO检查明显升高(100.00%vs 94.04%vs 98.84%、100.00%vs 93.75%vs 99.13%),差异有统计学意义(χ^(2)=23.045、68.023,P<0.05)。2DE联合LVO检查在舒张末期、收缩末期对于NVM患者NC发现率均较单一2DE检查、单一LVO检查明显升高(41.99%vs 23.28%vs 34.33%、40.82%vs 22.04%vs 32.14%),差异有统计学意义(χ^(2)=39.298、40.397,P<0.05)。2DE联合LVO检查NVM患者的舒张末期、收缩末期NC/C值较单一2DE检查、单一LVO检查明显升高,差异有统计学意义(F=4.132、6.265,P<0.05);2DE联合LVO检查NVM患者的LVEF与单一2DE检查、单一LVO检查相近,差异无统计学意义(P>0.05)。结论常规超声联合心脏声学造影检查能够提升NVM患者心肌节段清晰显示率、NC节段发现率及NC/C值,更有助于准确识别NVM。Objective To explore the diagnostic value of conventional ultrasound(2DE)combined with contrast echocardiography(LVO)for myocardial insufficiency(NVM).Methods A total of 43 patients with suspected LVNC diagnosed by conventional two-dimensional echocardiography(2DE)in the hospital from January 2017 to June 2021 were selected as the study subjects.All patients underwent left echocardiography(LVO)examination,using ultrasound diagnostic criteria recommended by Jenni et al.As the standard,according to AHA16 segment analysis.At the end of systole and end of diastole,2DE,LVO and 2DE combined with LVO were compared to evaluate the segmental display rate,NC segmental discovery rate,NC/C value and left ventricular ejection fraction(LVEF),and comprehensively evaluate the diagnostic value of 2DE combined with LVO for NVM.Results Among the 43 patients suspected of NVM by 2DE,32 met Jenni's diagnostic criteria for diagnosis.2DE combined with LVO significantly increased the rate of clear display of cardiac muscle segments at the end of diastole and end of contraction compared with 2DE alone and LVO alone(100.00%vs 94.04%vs 98.84%,100.00%vs 93.75%vs 99.13%),the difference was statistically significant(χ^(2)=23.045,68.023,P<0.05).Compared with 2DE alone and LVO alone,the detection rate of NC in NVM patients at the end of diastole and end of systole was significantly higher(41.99%vs 23.28%vs 34.33%,40.82%vs 22.4%vs 32.14%),the difference was statistically significant(χ^(2)=39.298,40.397,P<0.05).The NC/C value of 2DE combined with LVO was significantly higher than that of 2DE alone and LVO alone,and the difference was statistically significant(F=4.132,6.265,P<0.05).The LVEF of patients with NVM by 2DE combined with LVO was similar to that by 2DE alone or LVO alone,the difference was not statistically significant(P>0.05).Conclusion Conventional ultrasound combined with echocardiography can improve the clear display rate of myocardial segments,the discovery rate of NC segments and the NC/C value in patients with NVM,and it is more
