目的探讨老年高血压病患者血压昼夜节律变化与血同型半胱氨酸的关系。方法将68例老年原发性高血压病患者按照24小时动态血压检测结果分为A、B两组:A组为杓形组,共28例;B组为非杓形组,共40例,分别检测血同型半胱氨酸水平。结果 B组的血同型半胱氨酸水平明显高于A组(P<0.05)。结论老年高血压病患者血压昼夜节律变化与血同型半胱氨酸水平关系密切。
Objective To investigate the relationship between circadian rhythm of blood pressure and blood homocysteine in elderly patients with essential hypertension. Methods A total of 68 elderly patients with essential hypertension were divided into A group and B group according to the 24-hour ambulatory blood pressure test. Group A was a dipper-shaped group with 28 cases in total. Group B was non-dipper-shaped group with 40 cases in total. Blood homocysteine levels were measured. Results The level of plasma homocysteine in group B was significantly higher than that in group A (P <0.05). Conclusion The changes of circadian rhythm of blood pressure in elderly patients with hypertension are closely related to the blood homocysteine level.
