摘 要:目的探讨糖代谢异常(IGM)在原发性高血压(EH)患者动脉粥样硬化(AS)病变及动态血压异常中的作用。方法选取46例单纯EH及36例合并2型糖尿病(T2DM)的EH患者,对比分析两组患者的血糖、血脂、血尿酸、纤维蛋白原等代谢参数及颈动脉AS病变与24 h动态血压参数的差异,然后对合并T2DM的EH患者颈动脉内膜中层厚度(CIMT)与血糖代谢参数,以及CIMT与动态血压参数之间的相关性进行分析。结果合并T2DM的EH患者体质量指数(BMI)、空腹血糖(FBG)、餐后2 h血糖(2 h PBG)、糖化血红蛋白(Hb A1c)、三酰甘油(TG)、总胆固醇(TC)、低密度脂蛋白胆固醇脂(LDL-C)、载脂蛋白B(apo-B)、尿酸、纤维蛋白原浓度等代谢参数均显著高于单纯EH患者(P<0.05或P<0.01)。与单纯EH患者比较,合并T2DM的EH患者颈动脉AS发生率(80.6%比56.5%,P<0.05)及CIMT[(1.24±0.28)mm比(1.04±0.26)mm,P<0.01)]显著增高,且24 h平均收缩压(24 h-m SBP)[(136.81±10.44)比(131.22±9.75)](P<0.05)、日间平均收缩压(dm SBP)[(140.39±10.87)比(133.22±9.74)](P<0.01)、24 h平均脉压(24 h-m PP)[(65.56±5.01)比(59.57±4.82)](P<0.01)及日间平均脉压(dm PP)[(67.44±5.71)比(59.70±4.03)](P<0.01)均显著高于单纯EH患者的相应指标(P<0.05),而两组间其他动态血压参数的差异则无统计学意义(P>0.05)。Pearson相关分析显示,在合并T2DM的EH患者中,其CIMT与FPG(r=0.418,P=0.011)、Hb A1c(r=0.719,P<0.01)显著正相关,但与PBG无显著性相关(P>0.05);而动态血压参数中24 hm SBP(r=0.414,P=0.012)、dm SBP(r=0.422,P=0.01)、nm SBP(r=0.372,P=0.026)及24 h-m PP(r=0.639,P<0.01)、dm PP(r=0.545,P<0.01)、nm PP(r=0.696,P<0.01)均与CIMT显著正相关;24 h-m DBP、dm DBP及nm DBP则与CIMT的相关性无统计学意义(P>0.05)。结论糖代谢异常可与其他心血管疾病(CVD)危险因素协同作用,加重EH患者AS病变,进而导致血压波动异常。因此,改善这些EH患者的糖代谢状态可降低其心脑血管疾病并发症的危险。Objective To explore the roles of impaired glucose metabolism (1GM) in the pathologic process of atherosclerosis (AS) and abnormal fluctuation of blood pressure in the essential hypertension (EH) patients. Methods Patients with simple EH (n = 46) and with EH combined with type 2 diabetes mellitus (T2DM) (n = 36) were enrolled in the study. We conducted comparisons on the meta- bolic parameters [ such as blood glucose, blood lipids, body mass index (BMI), serum uric acid (UA) and fibrinogen (Fib), along with detection of atherosclerotic plaques as well as ambulatory blood pressure (ABP) ] between the two groups of patients, and then ana- lyzed the correlation in the patients with EH combined with T2DM. Results In comparison with the simple EH patients, the EH pa- tients combined with T2DM had significant increases in the levels of BMI, fasting blood glucose ( FBC), 2h- postprandial blood glucose (2h-PBG), hemoglobin Alc (HbA1c) , triglyceride (TG), low density ]ipoprotein-C (LDL-C), apo-B, and serum UA and Fib (P 〈 0.05 or P 〈0.01 ). They also showed significant increases in atherosclerotie plaque incidence (P 〈0.05), carotid intima-media thick- ness (CIMT) , 24h-or daytime systolic blood pressure (P 〈0.05) and pulse pressure (P 〈 0.01 ). In addition, Pearson correlation a- nalysis performed in those EH patients combined with T2DM revealed that CIMT was positively related with FBG ( r = 0. 418, P = 0.011 ) and HbA1 c ( r = 0.719, P 〈 0.01 ) significantly, but not with PBG ( P 〉 0.05 ). Besides, ABP parameters such as 24h-mean systolic blood pressure (mSBP) (r=0.414, P =0.012), day mSBP (dmSBP) (r=0. 422,P =0.01), night mSBP (nmSBP) (r= 0.372, P = 0.026 ), 24h-mean pulse pressure (mPP) ( r = 0. 639, P 〈 0.01 ), day mPP (dmPP) ( r = 0. 545, P 〈 0.01 ) and night mPP (nmPP) (r = 0.696 ,P 〈 0.01 ) were all positively related with CIMT significantly, although no
