1、非洛地平对高血压并发症前瞻性研究5年观察【内容摘要】 目的 5年随访观察非洛地平缓释片及氢氯噻嗪双盲对照对高血压疗效及心脑血管事件发生。方法 按中国医科院阜外医院fever研究规划,严格选择5070岁的高血压者,经3个月用慰藉剂观察期后血压在160180/90100mmhg之间。排除半年内心肌梗死、脑卒中、肿瘤等严重疾病。入选者按多中心双盲用非洛地平缓释片2.55mg/d或氢氯噻嗪12.525mg/d经5年随访。每例平均随访40次左右,治疗前后测坐立位血压、心率、空腹血糖、总胆固醇(tc)、甘油三酯(tg)、高密度脂蛋白胆固醇(hdl-c)、肌肝、尿酸、血清钾、心电图等。记录不稳定心绞痛、心肌
2、梗死、脑卒中、死亡的发生。结果 200例中死亡6例,失访14例,随访率达93%。其余180例开盲后分为非洛地平缓释片组(t组)94例,氢氯噻嗪对照组(c组)86例。两组年龄、性别、体重指数(bmi)、基础收缩压、舒张压组间比较p 0.05有可比性。治疗前t组收缩压160.307.99mmhg、舒张压94.492.70 mmhg,治疗后降到133.548.32 mmhg及82.355.06mmhg。本身前后对照p 0.01,两组间p 0.05。tc、tg,t组治疗前5.460.81 mmol/l、2.100.89 mmol/l,治疗后降到5.071.07 mmol/l、1.750.59 mmol
3、/l,前后和组间p均 0.01。hdl-c治疗前1.160.19 mmol/l,治疗后升高到1.200.21mmol/l,前后比p均 0.01,组间比p 0.01,差别显著。200例中发生心脑血管事件11例,t组4例,占4.26%;c组7例,占8.14%,肿瘤1例。 t组比c组减少心脑血管事件47.78%。 c组脑卒中3例(1例脑梗塞,2例脑出血)及心肌梗死1例、不稳定心绞痛3例、肿瘤1例。t组脑出血、 脑梗塞、心肌梗死、不稳定心绞痛各1例。共死亡6例(含 c组肿瘤1例):其中心脑血管事件5例,t组2例,占2.13%;c组3例,占3.49%,t组比c组减少心脑血管事件死亡38.97%。结论 非
4、洛地平缓释片及小剂量氢氯噻嗪经5年前瞻性研究,两者均有良好降压作用,t组尚有降低tc、tg及升高hdl-c; t组比c组减少心脑血管事件47.78%,减少心脑血管事件死亡38.97%,故以为t组减少心脑血管事件的发生优于c组。 【本文关键词语】 高血压前瞻性研究 心脑血管事件 非洛地平缓释片 氢氯噻嗪 prospective observation on felodipine in thetreatment of hypertension and cardiovascalar events you zhong-yi1 lu de-chen2 xie jin-xing1 【abstract】 o
5、bjective to compare prospectively the efficacy and safety of felodipine and hydrochlorthiazide in the treatment of hypertension following up five years. methods 180 cases with hypertension were divided into two groups randomizely and double-blindedly, t group(94 patients with felodipine 2.55mg twice

7、ids (tc、tg、hdl), renal function and serum potassium were monitored and recorded. the incidence rate of unstable cardiac angina, cardiac infarction, stroke and death were also recorded. results in t group, there were significantly differences in the blood pressure(sbp160.307.99mmhg, dbp 94.492.70mmhg
