Abstract
Background: Cardiovascular diseases are prevalent in people with chronic obstructive pulmonary disease (COPD). We hypothesized that endothelial dysfunction could be a marker of the proatherogen status in COPD.
Methods and results: We measured endothelial dysfunction by flow-mediated dilation (FMD) and after sublingual administration of nitroglycerin (nitrate-mediated dilation: NMD) in 44 COPD patients and 48 controls. Compared with controls COPD patients had worse mean FMD (5.4% vs 8.2%, P < .001) and NMD (12.0% vs 13.9%, P = .007). FMD was inversely related to FEV1/VC ratio (r = -0.327, P = .030). The negative association between COPD and FMD was confirmed after correction for potential confounders in a multiple linear regression model (beta = -0.019, P = .002). In the same model NMD (beta = 0.396, P < .001) was positively associated with FMD.
Conclusions: Endothelial-dependent and, to a lesser extent, endothelial-independent dilations are significantly impaired in COPD, and the impairment is proportional to the severity of bronchial obstruction.
背景:心血管疾病在慢性阻塞性肺疾病(COPD)患者中普遍存在。我们假设内皮功能障碍可能是COPD患者动脉粥样硬化状态的标志。方法和结果:我们通过血流介导的扩张(FMD)和舌下给药硝酸甘油(硝酸盐介导的扩张:NMD)测量了44例COPD患者和48例对照组的内皮功能障碍。与对照组相比,COPD患者的平均FMD (5.4% vs 8.2%, P < .001)和NMD (12.0% vs 13.9%, P = .007)更差。FMD与FEV1/VC比呈负相关(r = -0.327, P = 0.030)。在多元线性回归模型中校正潜在混杂因素后,证实COPD与FMD之间存在负相关(beta = -0.019, P = 0.002)。在同一模型中,NMD与FMD呈正相关(β = 0.396, P < 0.001)。结论:COPD患者的内皮依赖性扩张和较小程度的内皮非依赖性扩张均明显受损,且受损程度与支气管梗阻的严重程度成正比。
