目的：探讨α1受体阻滞剂乌拉地尔与其他传统治疗方法对比，是否可以获得额外临床收益。方法选择老年女性患者46例，随机分为乌拉地尔组24例，乌拉地尔50～300μg/min，硝酸甘油组22例，硝酸甘油5～20μg/min，总给药时间48～140h，根据血压及心功能状况调整药物浓度。在治疗前及治疗后1、2、3、7d观察血压、心率、代谢指标变化情况。结果乌拉地尔组治疗后7d收缩压控制明显优于硝酸甘油组[（108．12±6．54）mmHgvs（116.36±11．09）mmHg，1mmHg＝0．133kPa，P＜0．05]，N末端钠尿肽前体水平较硝酸甘油组明显下降[（2378．42±956．12）ng/Lvs（4546．14±457．73）ng/L，P＜0．01]。结论在老年女性患者中，乌拉地尔较硝酸甘油在降低和稳定收缩压方面有更好的疗效。并且在减轻心脏后负荷及改善心功能方面都优于硝酸甘油。%Objective To assess whether urapidil (anα1 receptor blocker)is more effective than ni-troglycerin in treatment of non-valvular heart failure accompanying hypertension and diabetes mellitus (DM ) in elderly female patients .Methods Fourty-six elderly female patients with non-valvular heart failure accompanying hypertension and DM were randomly divided into urapidil treatment group (n= 24) and nitroglycerin treatment group (n= 22) .Patients in urapidil treat-ment group were treated with urapidil (50 -300 μg/min) and those in nitroglycerin treatment group were treated with nitroglycerin (5 -20 μg/min) for 48 -140 h according to their blood pressure (BP) and cardiac function .Their BP ,HR ,and metabolic activity were observed before and on days 1 ,2 ,3 and 7 after treatment .Results The effect of urapidil was significantly lower than that of nitroglycerin on SBP on day 7 after treatment (P<0 .05) .The serum NT-proBNP level was significantly lower in nitroglycerin treatment group than in control group (P<0 .01) . Conclusion The effect of urapidil is better than that of nitroglycerin on reducing and stabilizing SBP ,attenuating cardiac afterload ,and improving cardiac function in elderly female patients .Ura-pidil can thus be used as one of the first choiced drugs in treatment of elderly female patients with non-valvular heart failure accompanying hypertension and DM .
