OBJECTIVEThrough 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.

METHODSHypertensive 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.

RESULTSWhen 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.

CONCLUSIONIt 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.
