Abstract

Ten patients with chronic obstructive pulmonary disease (COPD) with normal left ventricular function were given a single dose of captopril (0.25 mg/kg). Mean systemic arterial pressure, heart rate and coronary flow to the right ventricle were reduced significantly after captopril. In contrast captopril did not cause a significant fall in pulmonary arterial pressure or pulmonary vascular resistance. We conclude that captopril fails to produce haemodynamic benefits in such hypoxic patients and that angiotensin II is not playing a significant role in maintaining pulmonary vasoconstriction.

摘要

对10名左心室功能正常的慢性阻塞性肺疾病(COPD)患者给予单剂量卡托普利(0.25毫克/千克)。给予卡托普利后,平均体动脉压、心率和右心室冠状动脉血流量显著降低。相比之下,卡托普利并未导致肺动脉压或肺血管阻力显著下降。我们得出结论,卡托普利在此类缺氧患者中未能产生血流动力学益处,且血管紧张素II在维持肺血管收缩方面未发挥重要作用。
