[摘要] 目的 探讨慢性阻塞性肺疾病(COPD)与冠状动脉粥样硬化性心脏病(CAD)的相关性。 方法 回顾性分析2017年1月至2020年1月宁波市医疗中心李惠利医院收治的211例CAD合并COPD患者,根据SYNTAX评分分为三组,再根据《慢性阻塞性肺疾病全球倡议2019(GOLD2019)》分为四组。冠脉病变严重程度各组间比较采用方差分析;各计量资料与冠脉病变及COPD严重程度的相关性分析采用Spearman检验;COPD严重程度与CAD严重程度相关性分析采用Kendall's tau检验。 结果 COPD严重程度与CAD病变严重程度呈显著正相关(r>0,P<0.05);年龄、低密度脂蛋白胆固醇(LDL-C)、用力肺活量(FVC)与CAD严重程度呈显著正相关(r>0,P<0.05);第1秒用力呼气容积(FEV1)、FEV1/FVC与CAD严重程度呈负相关(r<0,P<0.05);年龄、LDL-C、FEV1预计值(preFEV1)、FVC與COPD严重程度呈正相关(r>0,P<0.05);FEV1、FEV1/FVC与COPD严重程度呈负相关(r<0,P<0.05)。 结论 肺功能参数和CAD病变严重程度及COPD严重程度具有相关性,且COPD严重程度与CAD严重程度呈正相关。

[Abstract] Objective To investigate the correlation between chronic obstructive pulmonary diseases(COPD) and coronary artery disease (CAD). Methods A total of 211 CAD patients with COPD admitted to Ningbo Medical Center Li Huili Hospital from January 2017 to January 2020 were retrospectively analyzed and divided into three groups according to SYNTAX score, and then divided into four groups according to Global Initiative for Chronic Obstructive Pulmonary Disease 2019(GOLD2019). Analysis of variance was used to compare the severity of coronary artery disease between the groups. Spearman test was used to analyze the correlation between each measurement data and the severity of coronary artery disease and COPD. Kendall's stau test was used to analyze the correlation between the severity of COPD and the severity of CAD. Results There was a significant positive correlation between the severity of COPD and the severity of CAD lesions (r>0, P<0.05). Age, low-density lipoprotein cholesterol (LDL-C), and forced vital capacity(FVC) were significantly positively correlated with CAD severity (r>0, P<0.05). Forced expiratory volume in one second (FEV1) and FEV1/FVC were negatively correlated with CAD severity (r<0, P<0.05). Age, LDL-C, predicted FEV1 (preFEV1), and FVC were positively correlated with COPD severity (r>0, P<0.05). FEV1 and FEV1/FVC were negatively correlated with COPD severity(r<0, P<0.05). Conclusion The results of this study suggest that there is a correlation between pulmonary function parameters and CAD lesion severity and COPD severity, and COPD severity is positively correlated with CAD severity.

慢性阻塞性肺疾病(Chronic obstructive pulmonary diseases,COPD)是气流受限不完全可逆的肺部疾病[1]。全球常见死因中COPD已上升至第三位[2-3]。COPD的症状及功能受限是由于气道阻塞、呼吸活动增加和气体交换障碍所致,最终可导致肺动脉高压、肺心病和心衰[4-6]。约20%的COPD患者无任何症状,但1 s用力呼气容积(Forced expiratory volume in one second,FEV1)降低是导致心血管事件的高危因素[7]。有研究[8-11]发现COPD患者中缺血性心脏病和心力衰竭的患病率较高。本研究旨在通过肺功能来探讨COPD与CAD病变严重程度的关系,现报道如下。
1 资料与方法
1.1 一般资料
回顾2017年1月至2020年1月于宁波市医疗中心李惠利医院住院的CAD合并COPD患者211例,据SYNTAX将患者分为三组:冠脉轻度(n=23)、中度(n=161)及重度组(n=27),据《慢性阻塞性肺疾病全球倡议2019(GOLD2019)》分为四组:GOLD1-1级组(n=44),GOLD1-2级组(n=136),GOLD1-3级组(n=28),GOLD1-4级组(n=3),且所有患者均行冠脉造影及肺功能检查且资料完整。本研究已通过宁波市医疗中心李惠利医院医学伦理委员会批准。排除标准:①患有除COPD外的其他呼吸疾病者;②既往有血管造影史、严重心脏瓣膜病史者;③有恶性肿瘤史者;④感染以及肝肾功能不全者。纳入……
