老年高血压病血压昼夜节律与左室肥厚的关系

The correlation between circadian rhythm of blood pressure and left ventricular hypertrophy in aged patients with hypertension

目的 :观察老年高血压病血压昼夜节律与左心室肥厚 (L VH)的关系。方法 :对 12 0例老年高血压患者行 2 4小时动态血压监测 (ABPM)以观察血压昼夜节律 ,用超声心动图检测左室重量指数 (L VMI) ,然后分析二者相关关系。结果 :血压昼夜节律减弱的 70例中 L VH有 41例 ,占 5 8.8% ;血压昼夜节律消失的 5 0例均有 L VH (10 0 % )。血压昼夜节律消失者的左室肥厚率显著的高于血压昼夜节律减弱者的 (P<0 .0 1)。结论

Objective:To observe the correlation between circadian rhythm of blood pressure (BP) and left ventricular hypertrophy (LVH) in aged patients with hypertension (EH).Methods: Ambulatory blood pressure monitoring and ultrasound cardiogram were performed in 120 aged patients with EH.Results: Patients with LVH were 41 cases (58 8%) in 70 patients with decrease of circadian rhythm of BP, those were 50 cases (100%) in 50 EH paitents with loss of circadian rhythm of BP.The difference of 2 group was very significant ( P <0 01).Conclusion:There are significantly negative correlation between LVH and decrease rate of night SBP?DBP in aged EH patients with hypertension.
