摘要 目的探讨Tei指数在评价高原地区(海拔3 800~4 500 m)肺心病患者右室功能的应用价值及藏汉之间是否存在差异。方法选取从高海拔地区来本院就诊的肺心病患者61例(汉族31例、藏族30例)和同期在本院体检的来自上述地区的健康人员70例(汉族45例、藏族25例)。采取经胸超声心动图检查,测量右房横径(RA)、右室前后径(RV)、右室前壁厚度(RVAW)及射血时间(ET)、右室Tei指数。结果汉族健康者Tei指数略低于健康藏族(P<0.05);汉族肺心病组RV、RVAW、Tei指数高于藏族肺心病组,但ET短于藏族肺心病患者(P均<0.01);藏、汉族肺心病组各指标均高于正常对照组(P<0.01)。在肺心病组,RVAW与Tei指数具有一定的相关性(r=0.72,P<0.001)。结论 Tei指数监测可有效评价高原地区肺心病患者右室功能,特别是高原低氧对右室功能的影响,具有较好的临床应用价值。
