摘要
目的:探讨高血压左心室肥厚(LVH)患者的心率变异性(HRV)以及分别受不同钙拮抗药的影响。方法:高血压左心室肥厚患者 70例随机分为维拉帕米、拉西地平组(各 35例),分别早上顿服缓释维拉帕米240 mg至 480 mg和拉西地平4 mg至6 mg,疗程12周。治疗前后测UCG、动态血压和动态心电图,观察降压和逆转LVH的疗效,以及分析HRV时域指标的改变情况。结果:治疗前患者的HRV降低;两药降低血压的幅度和逆转LVH的疗效相近;A组HRV指标经治疗后明显改善,而拉西地平组则改变不明显。结论:维拉帕米和拉西地平均能有效降低血压和逆转LVH,前者还可改善患者的HRV,可能对病人有远期益处。
Objectives: To explore influence of two types of calcium channel blockers on the heart rate variability (HRV) in essential hypertension patients with left ventricular hypertrophy (LVH). Methods: Seventy Patients were randomly assigned into two groups (35 each). Sustained-release preparation of verapamil (240 mg^480 mg) or lacidipine (4 mg^6 mg) was given to group A or B respectively once daily for 12 weeks. Echocardiography, ambulatory blood pressure monitoring and Holier electrocardiogram were carried out before and after therapy to evaluate their effects on blood pressure, LVH, and HRV. Results: HRV was reduced before treatment. Both drugs had similar effects on the blood pressure amplitude reduced and regression pf LVH. HRV criteria was improved after therapy in group A, but not in group B. Conclusion: Both verapamil and lacidipine can lower blood pressure and recess LVH effectively. Better improvement of HRV by verapamil may have long term benefits.
