摘要 目的观察紫杉醇治疗老年缺血性心律失常的效果,并探讨其作用机制。方法选取60例冠状动脉粥样硬化性心脏病并发室性心律失常的老年患者,随机分为135 mg/m2紫杉醇组(低剂量组)、155 mg/m2紫杉醇组(高剂量组)。两组均用生理盐水溶解药物,通过静脉给药,每日1次,每2 w停1 w作为1个疗程。经过3个疗程,比较两组治疗前后的左室舒张末内径(LVDD)、舒张末室间隔厚度(IVS)及左室后壁厚度(LVPW)及左室射血分数(LVEF)、心电图的主要差别。结果 135、155 mg/m2紫杉醇均可以降低缺血性室性早搏症状,且呈剂量依赖性,两组比较差异显著(P<0.05);相对于治疗前LVDD、IVS、LVPW指标,治疗后这些指标均明显降低(P<0.05);而治疗后的LVEF则明显比治疗前升高(P<0.01)。结论紫杉醇可以有效预防和控制缺血性室性心律失常,对保护缺血性心脏损伤具有重要作用。
