摘要(Abstract)：

目的利用磁共振电影成像技术探讨肥厚型心肌病患者左、右心室整体功能的变化。材料与方法连续收集自2013年2月至2014年2月在我院行心脏核磁共振检查的被拟诊为肥厚型心肌病的患者共26例,同期收集20例健康志愿者心脏核磁共振检查的图像。由两名放射科医师分别将26例肥厚型心肌病患者和20例健康志愿者的图像导入Report CARD3.6心脏功能分析软件进行相关数据测量,最终获得左、右心室的舒张末期容积(EDV)、收缩末期容积(ESV)、射血分数(EF)、每搏输出量(SV)以及左心室的短轴缩短率(FS)。肥厚型心肌病患者与健康志愿者之间左、右心室功能指标的比较采用独立样本t检验。结果肥厚型心肌病患者左心室整体功能的各项指标LVEDV、LVESV、LVEF、LVSV及FS分别为(88.94±13.29)ml、(24.75±7.31)ml、(71.70±7.60)%、(64.20±12.82)ml、(52.52±8.83)%,健康志愿者LVEDV、LVESV、LVEF、LVSV及FS分别为(107.93±12.62)ml、(34.18±3.6)ml、(67.25±4.48)%、(73.65±12.41)ml、(36.8±3.82)%,LVEDV、LVESV、LVSV数值较健康志愿者均减低,二者之间有显著性差异;LVEF较正常人增高,但没有显著性差异;FS较正常人显著增高,二者之间有显著性差异。肥厚型心肌病患者右心室整体功能各项指标RVEDV、RVESV、RVEF、RVSV分别为(88.48±17.67)ml、(29.84±7.50)ml、(6 4.6 5±1 0.2 7)%、(5 8.6 6±1 7.0 9)m l,健康志愿者RV E D V、RV E S V、RVEF、RVSV分别为(142.31±23.62)ml、(72.49±16.13)ml、(49.18±5.6)%、(69.82±13.43)ml,RVEDV、RVESV较正常人明显减低,二者之间有显著性差异;RVEF较正常人增高,二者之间有显著性差异;RVSV较正常人减低,二者之间没有显著性差异。结论在早期,肥厚型心肌病左心室舒张功能减低、收缩功能升高的同时,右心室的舒张功能也减低、收缩功能升高,左右心室的功能变化是一致的。
