Antihypertensive agents may modulate fibrinolysis in addition to reducing blood pressure. We conducted a randomized trial to assess the effects of lercanidipine and losartan on blood pressure (BP) lowering and three fibrinolytic parameters: plasminogen activator inhibitor-1 (PAI-1), D-dimer, and fibrinogen. All patients enrolled had essential hypertension and underwent a placebo run-in period of 2 weeks before randomization to either lercanidipine tablets 10-20 mg once daily or losartan tablets 50-100 mg once daily. Twenty-six patients completed this study. After 8 weeks of treatment, both groups of patients had significantly reduced systolic (SBP) and diastolic BP (DBP) (SBP, p = 0.034 and 0.050, respectively; DBP, p = 0.018 and 0.034 for lercanidipine and losartan, respectively). Both drugs were well tolerated. Only in the group treated with lercanidipine was PAI-1 concentration significantly reduced (57.1 +/- 4.7 to 43.1 +/- 4.8 ng/mL, p = 0.047). No difference was found with D-dimer and fibrinogen in either group. This study shows that both lercanidipine and losartan are effective antihypertensive drugs in patients with essential hypertension. Lercanidipine may provide additional benefit in fibrinolysis.
除降低血压外,抗高血压药物可能还会调节纤维蛋白溶解。我们进行了一项随机试验,以评估乐卡地平与氯沙坦对降低血压及三项纤维蛋白溶解参数的影响,这三项参数分别为纤溶酶原激活物抑制剂-1(PAI-1)、D-二聚体和纤维蛋白原。所有入组患者均患有原发性高血压,在随机分组接受每日一次10 - 20毫克乐卡地平片或每日一次50 - 100毫克氯沙坦片治疗之前,先经历了为期2周的安慰剂导入期。26名患者完成了本研究。治疗8周后,两组患者的收缩压(SBP)和舒张压(DBP)均显著降低(SBP,乐卡地平组和氯沙坦组分别为p = 0.034和0.050;DBP,乐卡地平组和氯沙坦组分别为p = 0.018和0.034)。两种药物耐受性均良好。仅乐卡地平治疗组的PAI-1浓度显著降低(从57.1±4.7降至43.1±4.8 ng/mL,p = 0.047)。两组的D-二聚体和纤维蛋白原均无差异。本研究表明,乐卡地平和氯沙坦对原发性高血压患者均为有效的抗高血压药物。乐卡地平可能在纤维蛋白溶解方面带来额外益处。
