Method: 215 cases of patients with hypertension from January 2015 to June 2016 were randomly selected from TianYou Hospital attached to WUST.Blood pressure was monitored 24 hours;according to the results, patients were divided into 81 cases of morning blood pressure surge group (study group) and 134 cases of non-morning blood pressure surge group (control group). Biochemical indicators of the two groups were measured, such as Hcy, Glu, blood lipid (TC, TG, LDL-C, HDL-C). The ventricular structure index (IVST, LVDD, LVPWT, LVMI) were measured by color doppler ultrasound.Result: 1) The IVST, LVDD, LVPWT and LVMI were significantly higher in study group than in control group (P 0.05), and the incidence of left ventricular hypertrophy (LVH) (74.1%) was significantly higher in study group than in control group (22.4%) (P 0.05). 2) There was no statistical difference in TC, TG, LDL-C and HDL-C between the two groups (P > 0.05). The serum levels of Hcy [(16.89 ± 5.84) mmol/L] in study group were significantly higher than those in control group [(10.88 ± 4.07) mmol/L] (P 0.05). 3) Multivariate logistic regression analysis showed that morning blood pressure surge and Hcy were the risk factors of left ventricular hypertrophy. Conclusion: In elderly patients with?hypertension, the higher the morning blood pressure surge and Hcy level, the more probability of left ventricular hypertrophy and the more obvious degree.展开更多
