摘要 目的探讨卡维地洛对慢性充血性心力衰竭(CHF)的临床疗效和对心室重塑的影响。方法66例CHF患者在应用硝酸酯制剂、利尿剂、洋地黄等常规治疗的基础上,随机分为A、B两组。B组在A组常规治疗基础上口服卡维地洛,起始量为2.5mg,2次/d,逐渐递增至目标剂量20mg,2次/d,维持稳定剂量至3个月。治疗前、后分别进行心功能(NYHA分级)评估,行超声心动图检查,6min步行距离分析。结果卡维地洛治疗3个月后心功能分级明显改善,左室舒张末内径(LVEDD)、左室收缩末内径(LVESD)缩小,相对室壁厚度(RWT)增厚,左室射血分数(LVEF)、每搏输出量(SV)、短轴缩短率(FS)明显提高,6min步行距离明显增加,上述指标与该组治疗前及与A组治疗后比较差异有统计学意义。结论卡维地洛对CHF,患者有较好疗效,并可显著逆转心室重塑,安全可靠。
