             [摘    要] 目的:探讨氯沙坦钾对心脏X综合征(cardiac syndrome X,CSX)的临床疗效并对治疗效果进行预测因素分析。方
              法:将2015年1月—2019年6月南京医科大学第二附属医院门急诊收治的86例X综合征女性患者随机分为两组:治疗组(n=
              42)予氯沙坦钾口服20周,安慰剂组(n=44)予安慰剂治疗。通过颈部血管彩色多普勒超声及西雅图心绞痛量表(Seattle angi⁃
              na questionnaire,SAQ)进行随访,对比治疗后两组患者的临床疗效,并对治疗效果进行预测因素分析。结果:86例患者均完成
              了20周的治疗,并重复进行了SAQ评估,治疗组与安慰剂组基线资料匹配度高。与安慰剂组相比,治疗组心绞痛频率明显降
              低,生活质量及机体功能状态较好(P=0.031)。氯沙坦钾治疗(P=0.04)、颈内动脉阻力指数(P=0.037)和较低的基线心绞痛发
              生率(P<0.001)是改善心绞痛评分的重要独立预测因素。结论:在无梗阻性冠心病的情况下,予氯沙坦钾治疗可改善有缺血
              症状和体征的X综合征女性的微血管功能,这种改善与动脉阻力下降和心绞痛的减少有关。

             [Abstract] Objective:To investigate the clinical efficacy of losartan potassium in the treatment of cardiac syndrome X(CSX)and to
              analyze the predictive factors of its therapeutic effect. Methods:A total of 86 female patients with CSX admitted to our hospital from
              January 2015 to June 2019 were randomly divided into two groups:the treatment group(n=42)received losartan potassium orally for 20
              weeks,and the placebo group(n=44)received placebo treatment. The clinical efficacy and predictive factors of treatment effect were
              compared between the two groups. Results:86 women completed 20 weeks of treatment and repeated the Seattle angina questionnaire
             (SAQ)assessment. The baseline data of the treatment group and the placebo group matched well. Compared with placebo group,the
              treatment group was associated with improved frequency of angina pectoris,lower incidence of angina pectoris,better quality of life and
              body function(P=0.031). Losartan potassium treatment(P=0.04),Internal carotid artery resistance index(P=0.037)and lower baseline
              angina freedom(P<0.001)were important independent predictors of improving angina score. Conclusion:In the absence of
              obstructive coronary heart disease,losartan potassium therapy can improve microvascular function in CSX women with ischemic
              symptoms,which is related to the decrease of arterial resistance and angina.
