老年高血压脉压与胆红素、踝臂指数的关系

Relationship between ambulatory pulse pressure, serum bilirubin and ankle brachial index in elderly people with essential hypertension.

目的探讨老年高血压病患者动态脉压与胆红素、踝臂指数的关系。方法将68例老年原发性高血压病患者按照脉压的不同，分为两组：A组（P〈60mmHg），B组（P≥60mmHg），分别测定胆红素、踝臂指数。结果随着脉压水平越高，胆红素、ABI水平越低，A组〉B组（P〈0．01）。结论老年高血压患者脉压增高与胆红素及ABI降低有关，脉压、踝臂指数、血清胆红素均可早期预测动脉粥样硬化，适当降低脉压、升高踝臂指数、提高血清胆红素水平可减轻高血压靶器官损害。

Objective To investigate the relationship between ambulatory pulse pressure, serum bilirubin and ankle brachial index （ABI）. Method 68 elderly essential hypertensive patients were divided into 2 groups according to PP, A group（P 〈 60 mmHg）, B group（P ≥60 mmHg）. Their ABI and serum bilirubin were measured and compared by the statistical software. Results The difference of ABI and serum bilirubin were significant, A group 〉 B group（ P 〈 0.01 ）. Conclusion In elderly essential hypertensive patients, serum bilirubin and ABI were correlated with pulse pressure. ABI,pulse pressure and serum bilirubin could predict the atherosclerosis progression.
