Serum MK-422 and plasma angiotensin converting enzyme activity were measured during the introduction of enalapril therapy in eight patients with heart failure. In a second study of 16 patients, we recorded exercise tolerance, clinical status and haemodynamics before and after 12 weeks of placebo or enalapril treatment. Increasing doses of enalapril gave step-wise increments in serum MK-422. Plasma converting enzyme activity remained low for at least 24 h after each dose of enalapril (5, 10 and 20 mg). Compared to placebo patients (n = 8), those receiving enalapril (n = 8) tended to improve their exercise performance and clinical status, and showed a fall in right heart pressures after 12 weeks of treatment.
在对8例心力衰竭患者引入依那普利治疗期间,测定了血清MK - 422和血浆血管紧张素转换酶活性。在另一项针对16例患者的研究中,我们记录了安慰剂或依那普利治疗12周前后的运动耐量、临床状况和血流动力学。依那普利剂量增加时,血清MK - 422呈逐步上升。每次给予依那普利(5、10和20毫克)后,血浆转换酶活性至少在24小时内保持较低水平。与接受安慰剂的患者(n = 8)相比,接受依那普利的患者(n = 8)在治疗12周后运动表现和临床状况趋于改善,右心压力下降。
