摘要 目的探讨高血压患者内皮素(ET)、血管紧张素Ⅱ(Ang-Ⅱ)、动态血压对左房内径的意义。方法将167例高血压患者分为左房内径扩大(LAE)组49例与非左房内径扩大(NLAE)组118例,对照组为健康检查正常者110例,经测定血ET、Ang-Ⅱ、动态血压参数、彩色超声心动图等进行比较。结果(1)Age、Sex、BMI、cSBP、cDBP、HR、BUN、Cr、TG、ApoB、LDL-C、Glu、动态血压节律、血压水平分类在LAE组与NLAE组间齐同,差异均无统计学意义(P>0.05)。(2)LAE组与NLAE组比较,超声左心结构各参数均显著增大(P<0.01)[RWT(49.17±11.23)%比(46.00±8.93)%(P<0.05)],Ang-Ⅱ(86.87±26.14)pg/ml比(85.93±22.40)pg/ml、ET(63.49±15.06)pg/ml·比(59.90±12.82)pg/ml(P>0.05),nSBP(125.65±20.54)mm Hg比(118.92±18.54)mm Hg、nSBPL(54.33±33.43)%比(42.83±33.43)%、24hPP(58.73±15.41)mm Hg比(54.28±12.85)mm Hg、nPP(55.84±19.08)mm Hg比(50.32±15.27)mm Hg(P<0.05),EF(63.82±13.29)%比(64.48±11.56)%、E/A(1.05±0.38)比(1.06±0.52)(P>0.05)。(3)相关分析:LAI与nSBP、nSBPL、24hPP、nPP相关系数分别为r=0.221、0.223、0.208、0.191(P<0.01),与Ang-Ⅱr=0.133(P<O.05)、与ET r=0.026(P>0.05)、与超声左心结构各参数均呈正相关(P<0.01)[与RWT r=0.147(P<0.05)],与EF、E/A呈负相关,系数分别为r=-0.089、-0.053(P>0.05)。结论ET、Ang-Ⅱ、动态血压对左房内径扩大起重要作用,而夜间收缩压水平、负荷和脉压是引起左房内径扩大的主要动态血压成分。
