[摘要] 目的 探讨替米沙坦对高血压合并冠心病患者心功能及炎性因子的影响。 方法 将126例高血压合并冠心病患者随机分为对照组与观察组,对照组60例患者给予硝苯地平缓释片降压,观察组66例给予替米沙坦口服,疗程均为6个月,比较治疗前后两组患者血压、心功能及炎性因子的改变。 结果 治疗后6个月两组收缩压及舒张压均无显著差别(P > 0.05);观察组左室射血分数(LVEF)、心脏指数(CI)及心脏舒张功能指标E/A比值显著优于对照组(P < 0.05);观察组治疗后血清超敏C—反应蛋白(hs—CRP)、肿瘤坏死因子—α(TNF—α)及白细胞介素—6(IL—6)显著低于对照组(P < 0.05)。 结论 替米沙坦可显著减少高血压合并冠心病患者血清炎症因子水平,改善患者心功能及左室重塑,有利于改善患者预后。

[Abstract] Objective To explore the influence of telmisartan on cardiac function and inflammatory factors in hypertension combining coronary heart disease patients. Methods All 126 cases with hypertension combining coronary heart disease were randomly divided into control group and experience group. 60 cases of control group were given sustained—release nifedipine treatments and 66 patients of experience group received telmisartan treatment. Blood pressure, cardiac function and inflammatory factors before and after treatment were compared between two groups. Results There were no significant difference of blood pressure 6 months after treatment between two groups (P > 0.05); LVEF, CI and E/A in experience group were superior to that in control group (P < 0.05); Hs—CRP, TNF—αand IL—6 after treatment in experience group were much lower than that in control group (P < 0.05). Conclusion Telmisartan can greatly decrease the inflammatory factors level in hypertension combining coronary heart disease patients, and improve the patients’ cardiac function, left ventricular remodeling and prognosis.

原发性高血压是心脑血管疾病的危险因素,合并冠心病的患者病死率明显增加。在动脉粥样硬化的形成过程中,自始至终存在炎症反应,炎症因子水平与患者预后密切相关。肾素—血管紧张素—醛固酮系统的激活在高血压患者左室重塑中发挥重要作用,替米沙坦是特异性的强效非肽类血管紧张素受体阻断剂[1]。本组研究的目的是探讨替米沙坦对高血压合并冠心病患者心功能及炎性因子的影响,为临床治疗方案的选择提供理论依据。
1 资料与方法
1.1 一般资料
选择2009年4月~2011年4月本院诊治的126例高血压合并冠心病患者为研究对象,所有患者均符合WHO关于高血压的诊断标准,且患者有心前区疼痛等症状,行心电图及冠脉造影检查证实为冠心病。126例患者中男68例,女58例。年龄46~80岁,中位数年龄63.5岁。126例患者中伴有左室肥厚者67例,不伴有左室肥厚者59例。除外继发性高血压、心肌病、瓣膜病、糖尿病、全身感染性疾病及恶性肿瘤等。将126例患者随机分入对照组与观察组,其中对照组60例,观察组66例,两组患者在年龄、性别等临床资料方面差异无统计学意义(P > 0.05),具有可比性。
