title: [Characteristics and related risk factors of arterial elasticity in prehypertensive persons].
abstract: OBJECTIVE
  To explore the characteristics and related risk factors of arterial elasticity in persons with prehypertension, high-normal blood lipid and(or) impaired glucose regulation(impaired fasting glucose and(or) impaired glucose tolerance).
  
  
  METHODS
  After receiving physical and biochemical examinations, a total of 1238 persons were enrolled. Among them, the etiologies were prehypertension (n = 65), high-normal blood lipid (n = 156), impaired glucose regulation (n = 159), prehypertension and high-normal blood lipid (n = 85), prehypertension and impaired glucose regulation (n = 77), high-normal blood lipid and impaired glucose regulation (n = 55) and prehypertension, high-normal blood lipid and impaired glucose regulation (n = 9). Also 332 healthy subjects, 113 hypertensive patients, 150 hyperlipidemics and 37 diabetics were enrolled as controls. Systemic vascular compliance (SVC), systemic vascular resistance (SVR), brachial artery distensibility (BAD) were measured with Dynapulse 200 M (Pulse Metric, Inc., USA).
  
  
  RESULTS
  In persons with prehypertension, SVC was lower than healty group ((1.14 ± 0.20) ml vs (1.26 ± 0.23) ml, P < 0.01)and higher than hypertensive group ((1.11 ± 0.18) ml, P = 0.011), SVR higher than healty group (157 ± 29) kPa×s×L(-1) vs (148 ± 25) kPa×s×L(-1), P = 0.012) and lower than hypertensive group ((166 ± 36) kPa×s×L(-1), P < 0.01)and BAD lower than healty group(5.93% ± 1.14% vs 6.50% ± 1.30%, P < 0.01). Among different groups with prehypertension, high-normal blood lipid and(or) impaired glucose regulation, SVC, SVR and BAD had significant differences. As indicated by multiple linear regression analysis, blood pressure was an independent risk factor of arterial elasticity.
  
  
  CONCLUSIONS
  Vascular function becomes damaged in prehypertensive stage. As an independent risk factor, blood pressure had more potent effect than lipid and blood glucose. Multiple cardiovascular risk factors with high-normal value may affect vascular function more strongly.
