【摘要】 对４０例原发性高血压患者采用２４小时动态血压监测方法对β受体阻滞剂（比索洛尔、阿替洛尔）进行降压疗效的比较。结果显示：２种药物均能达到全天的降压疗效；比索洛尔２４小时对收缩压及舒张压的降压作用强于阿替洛尔；比索洛尔２４小时中对舒张压降低的百分率明显强于收缩压，并能在夜间保持持续降压状态；２种药物对心率的降低无差异性。这提示，比索洛尔的降压疗效（２４小时１次口服）优于阿替洛尔。更多还原

【Abstract】 The comparative efficacy of oral bisoprolol(5 mg/day , n= 20)and atenolol(50 mg/day ,n= 20)in the treatment of hypertension had been assessed by 24 h ambulatory blood pressure monitoring. The results showed that hypertension could be controlled by both drugs. But the SBP and DBP were much reduced by bisoprolol than by atenolol,especially the DBP could be kept at normal level for all night. Heart rate showed no significant difference in both groups. Conclusion:The efficacy of bisoprolol in the treatment of hypertension seems much better than that of atenolol.更多还原
