钙拮抗剂为基础的联合降压效优

  发表于2012年第3期《中华高血压杂志》上研究表明,以钙拮抗剂氨氯地平为基础,联合替米沙坦或复方阿米洛利均能够降低高血压患者中心动脉压(CAP)、增强指数和改善大动脉顺应性,其中氨氯地平联合替米沙坦改善动脉弹性更明显,并且随着治疗时间的延长,效果更佳。   研究旨在探讨氨氯地平联合复方阿米洛利或联合替米沙坦对CAP和脉搏波传导速度(PWV)的影响。研究者们采用随机抽样方法选取2008-03-

  发表于2012年第3期《中华高血压杂志》上研究表明,以钙拮抗剂氨氯地平为基础,联合替米沙坦或复方阿米洛利均能够降低高血压患者中心动脉压(CAP)、增强指数和改善大动脉顺应性,其中氨氯地平联合替米沙坦改善动脉弹性更明显,并且随着治疗时间的延长,效果更佳。

  研究旨在探讨氨氯地平联合复方阿米洛利或联合替米沙坦对CAP和脉搏波传导速度(PWV)的影响。研究者们采用随机抽样方法选取2008-03-2011-02济南4个社区查体人群中高血压患者275例,年龄50~79岁。随机分为氨氯地平联合复方阿米洛利组(A组,134例)或联合替米沙坦组(B组,141例)。排除68例应用调脂药物的患者后,对207例(A组,102例;B组,105例)患者进行分析。在基线、治疗12、24月,分别应用动脉脉搏波分析仪测量CAP和增强指数,应用PWV测定仪测定颈桡动脉PWV(crPWV)。

  结果 显示,两组治疗12月后,中心动脉收缩压、舒张压、脉压,增强指数及crPWV均明显降低。24月时,B组crPWV较12月时进一步降低 [(8.9±2.0)比(9.5±2.2)m/s,P<0.05 ],然而A组患者的crPWV并未随着时间的延长进一步改善(P>0.05)。治疗12和24月后,B组crPWV下降幅度 [12月(-3.5±2.1)m/s,24月(-4.1±2.3)m/s ]均较A组 [12月(-2.3±1.6)m/s,24月(-2.5±1.8)m/s ]更明显(均P<0.01)。
