The changes and impact factors of carotid-femoral and carotid-radial pulse wave velocity in patients with essential hypertension / 中华心血管病杂志

<p><b>OBJECTIVE</b>To analyze the changes of carotid-femoral and carotid-radial pulse wave velocity in patients with essential hypertension, and effects of age and levels blood pressure levels on these changes.</p><p><b>METHODS</b>Automatic pulse wave velocity (PWV) measuring system was applied to examine carotid-femoral PWV (CFPWV) and carotid-radial PWV (CRPWV) as the parameters reflecting central elastic large arterial and peripheral muscular medium-sized arterial elasticity respectively. 517 hypertensive patients aged 17-82 years (272 males and 245 females, mean age 52.0 +/- 13.0 years) and 118 healthy subjects aged 19-82 years (52 males and 66 females, mean age 54.2 +/- 13.8 years) were recruited in the study.</p><p><b>RESULTS</b>CFPWV increased with age in both groups (P < 0.001), whereas CRPWV did not change significantly. CFPWV and CRPWV both increased with blood pressure. A stepwise multiple regression analysis demonstrated that age and systolic blood pressure were positively related to CFPWV independently, while diastolic blood pressure was significantly associated with CRPWV.</p><p><b>CONCLUSIONS</b>Age and components of blood pressure exert different effects on elasticity of central elastic large artery and peripheral muscular medium-sized artery. Examining the change of large arterial elasticity has important clinical value in hypertensive patients.</p>

A study on the risk factors of cardiovascular between hypertensive patients and normal subjects in the same family / 中华流行病学杂志

<p><b>OBJECTIVE</b>Through studying the difference between the hypertensive patients and those with normal blood pressure who all from the same hypertensive pedigree, we tried to find the factors which would decrease the risk of hypertension.</p><p><b>METHODS</b>Hypertensive patients, when coming to the cardiovascular clinic of Xuan Wu Hospital from 2003 to 2004, were defined as the members of the hypertensive pedigrees through inquiry. 84 families including 368 persons, with 192 syblings were involved. Metabolic syndrome could be defined by the criterion of adult treatment panel III.</p><p><b>RESULTS</b>When compared with normal blood pressure persons, clinical examinations of the hypertensive patients had an higher levels of triglyceride, total cholesterol, glucose and body mass index (BMI). The hypertensive group showed higher ratios among male patients, smokers, alcohol drinkers, having irritable personality and high-salt-intake. Through logistic regression, overweight, smoking and irritable temperament showed positive relations with hypertension. The rate of metabolic syndrome was higher in hypertension group.</p><p><b>CONCLUSION</b>It is important that either persons with normal blood pressure or hypertension should control their body weights (BMI) since the rate of metabolic syndrome in hypertension group was high.</p>
