目的观察老年心功能不全患者24 h动态血压昼夜节律的变化,探讨动态血压监测在老年心功能不全患者病情评估中的价值。方法将108例老年心功能不全患者根据纽约心脏病协会(NYHA)心功能分级进行准确分级并记录,同时选取同期83例有基础心脏病但无心功能不全的老年患者作为对照组,分别予24 h动态血压监测(24 hABPM),比较各组的动态血压参数。结果与对照组相比,老年心功能不全患者中血压昼夜节律消失的比例明显升高,且心功能Ⅲ、Ⅳ级患者昼夜节律消失的发生率明显高于心功能Ⅱ级患者(均P<0.05)。结论老年心功能不全患者血压昼夜节律消失的发生率增高,并与心功能不全的严重程度相关。
Objective To observe the changes of ambulatory blood pressure circadian rhythm at 24 hours in elderly patients with cardiac insufficiency and to explore the value of ambulatory blood pressure monitoring in the evaluation of the condition of elderly patients with cardiac dysfunction. Methods One hundred and eighty elderly patients with heart failure were accurately graded and recorded according to New York Heart Association (NYHA) classification. 83 elderly patients with underlying heart failure but no cardiac insufficiency during the same period were selected as control group, Ambulatory blood pressure monitoring (24 hABPM), dynamic blood pressure parameters of each group were compared. Results Compared with the control group, the rate of disappearance of circadian rhythm of blood pressure in elderly patients with cardiac insufficiency was significantly higher than that of the control group (P <0.05), and the incidence of circadian rhythm disappearance in patients with grade Ⅲ and Ⅳ cardiac function was significantly higher than those in patients with grade Ⅱ cardiac function ). Conclusion The incidence of disappearance of circadian rhythm of blood pressure in elderly patients with cardiac insufficiency is increased, which is related to the severity of cardiac insufficiency.
