Abstract:
ObjectiveTo evaluate arterial stiffness and its influencing factors in the elderly patients with hypertension and (or) type 2 diabetes mellitus.MethodsTotally 320 elderly patients were divided into four groups: control,diabetes mellitus,hypertension,coexisting hypertension and diabetes mellitus.Arterial stiffness in ankle and brachial artery was determined by brachial-ankle pulse wave velocity (baPWV).Other factors affecting baPWV were also collected and measured,including age,body mass index (BMI),sex,smoking,blood pressure,pulse pressure,mean arterial pressure,serum fasting blood glucose,lipid profile,glycosylated hemoglobin and hypersensitive C-reactive protein (hsCRP).ResultsbaPWV in the four groups were ( 1667.2 ± 279.3 )cm/s,(2158.6 ±386.9)cm/s,(1881.2±383.8) cm/s and (2165.9± 479.9)cm/s,respectively.The baPWV value was higher in groups of hypertension,diabetes mellitus,and the coexisting diseases than in controls (F=8.473,P＜0.05).Diabctic patients had a higher baPWV levels than those without diabetes.There was no difference in baPWV levels between diabetic patients with or without hypertension.Pulse pressure and hsCRP were higher in coexisting diseases group than in control group (P＜0.05).Stepwise backward regression analysis showed that fasting blood glucose,pulse pressure,mean blood pressure,hsCRP and low density lipoprotein cholesterin (LDL-C) were positively related to baPWV P ＜0.05). ConclusionsHypertension and (or) type 2 diabetes mellitus are important influencing factors for higher arterial stiffness. Hyperglycemia might play more important role in the elderly arterial stiffness.Serum fasting blood glucose,pulse pressure,mean blood pressure,hsCRP,LDL-C may be the independent risk factors of arterial stiffness.
