摘要 目的 评价L -精氨酸 (L Arg)治疗老年慢性心力衰竭的疗效及安全性。方法  3 6例心衰患者 (NYHA心功能分级Ⅳ级 1例 ,Ⅲ级 2 4例 ,Ⅱ级 11例 ) ,以 2 0 %L Arg10 0ml加入 5 %葡萄糖溶液 10 0ml,1小时内恒速静滴 ,1次 /d ,连续 7天。记录用药前后心率、血压、心功能变化。同时测定用药前后血浆NO ,ET和尿液NO。结果 静滴L Arg 5分钟后收缩压、舒张压、收缩压与心率乘积均有显著降低 (P <0 0 5 )。最大效应时间 10~ 60分钟 ,心率无变化。 7天疗程结束时 ,显效 13例 ,有效 18例 ,总有效率 86 11%。同时 ,治疗前血NO、ET ,尿液NO明显升高 ,治疗后血浆ET显著降低 ,尿液NO明显升高 ,血浆NO及生化指标 (K ,Na ,Cl ,BUN ,Cr)无变化。无低血压反应和心衰进一步加重。结论 静滴L Arg治疗老年性充血性心力衰竭 ,可取得良好的血液动力学效果 ,且安全性高 ,耐受性好。
