倍他乐克联合硝苯地平缓释片治疗原发性高血压疗效观察

目的：探讨倍他乐克联合硝苯地平缓释片治疗原发性高血压的临床疗效。方法：将我院新近发现的60例原发性高血压患者,随机分为对照组和治疗组,每组各30例。对照组给予硝苯地平缓释片10 mg/次,每日2次于早8点和晚8点口服;治疗组硝苯地平缓释片用法同对照组,但于午餐前增加口服倍他乐克25 mg。每周测血压2次,共8周。结果：对照组显效11例,有效11例,无效8例,总有效率为73.3%（22/30）;治疗组显效18例,有效11例,无效1例,总有效率为96.7%（29/30）。两组总有效率比较,差异有统计学意义（χ2=7.134,P〈0.05）。对照组治疗前后心率无明显改变（P〉0.05）;治疗组心率平均下降10次/min,与治疗前及对照组相比差异均有统计学意义（均P〈0.05）。结论：倍他乐克联合硝苯地平缓释片治疗原发性高血压疗效好,且有相互协同作用,值得临床推广。
