Keyword:  球形指数左心室健康成人单心动周期实时三维超声;
Abstract: 目的应用单心动周期实时三维超声心动图(sRT-3DE)探讨健康成人左心室球形指数(LVSI)及其变化规律。方法使用sRT-3DE检查291例研究对象,所测LVSI与左心室容积进行相关性分析;探讨其在性别和不同年龄的差异性,并与二维超声心动图(2DE)所测LVSI相比较。结果健康成人sRT-3DE所测LVSI分别为舒张末(43.05±6.47)%和收缩末(35.90±7.70)%,其与左心室容积之间有相关性;sRT-3DE所测LVSI优于2DE;不同年龄、性别之间健康成人LVSI差异无统计学意义(P>0.05)。结论初步建立健康成人三维超声LVSI参考值范围,舒张末LVSI不受年龄和性别的影响,其方法学优于2DE,为进一步深入研究和临床推广应用提供了依据。
