摘要 目的:探讨慢性充血性心力衰竭继发肺动脉高压患者的临床特点,分析继发性肺动脉高压形成的相关临床因素。方法:169例因充血性心力衰竭而住院的患者,根据多普勒超声心动图估测肺动脉收缩压,分为继发性肺动脉高压组(68例)和正常肺动脉压组(101例),比较两组的一般资料(年龄、性别、病因、病程及心功能NYHA分级),临床合并情况(高血压病、糖尿病及心房纤颤)及超声心动图参数(左房内径、左室舒张末期内径及左室射血分数)。在两组比较的基础上行Logistic回归分析继发性肺动脉高压形成的危险因素。结果:两组患者的一般资料,合并高血压病及心房纤颤的情况及左房内径、左室舒张末期内径比较差异无显著性。继发性肺动脉高压组较正常肺动脉压组合并糖尿病的情况明显增加(41.2%vs26.7%,P=0.049),左室射血分数较正常肺动脉压组降低[(35.43±8.66)%vs(38.53±6.71)%,P=0.014]。Logistic回归分析示是否合并糖尿病及左室射血分数的β系数分别为0.803和0.367,P值分别为0.022和0.003。结论:合并糖尿病及左室射血分数下降与慢性充血性心力衰竭患者继发性肺动脉高压形成有关。
