1、从最新研究证据重新思考b-受体阻滞剂在降压治疗中的地位,河北省人民医院郭艺芳,Lindholm荟萃分析主要结果,Lancet 2005;366:1545,-受体阻滞剂在预防心脏性猝死方面并不优于其他任何降压药物,但在预防卒中方面却显著劣于其他药物,Lindholm荟萃分析主要结论,Only minimal evidence suggests -blockers reduce the morbidity and mortality associated with hypertension, especially among the elderly. Clinicians must be scep
2、tical of using drugs for which only surrogate marker evidence is available. All patients 60 and older who are taking -blockers for hypertension alone should be reassessed because -blockers are not in a class of agents that reduces morbidity and mortality.
