摘要:临床上,慢性阻塞性肺疾病(COPD)和冠心病(CAD)常相互影响,促进疾病进展。本文从生理上论述宗气为心肺相关的功能基础,营卫相关是心肺相关的核心;从病理上探讨宗气亏虚是COPD和CAD发病基础,营卫交会生化紊乱是COPD合并CAD的核心机制,痰瘀毒互结难解,进一步损伤精气是COPD合并CAD进展的关键因素。由此为下一步临床辨证及制定综合治疗方案与临床科研奠定基础。

Abstract: Clinically, chronic obstructive pulmonary disease (COPD) and coronary heart disease (CAD) often interact to promote disease progression. This article discussed that zongqi is the heart-lung correlation functional basis and yingwei relevant is heart-lung correlation core. Zongqi deficiency is the incidence basis of COPD and CAD from the pathology. Communication and transformation of nutrient and defensive qi is the core mechanism of COPD combined with CAD. Phlegm and blood stasis are toxic intricate. Further damage to jingqi is the key to combination of COPD and CAD. It lays the foundation for next clinical syndrome differentiation, development of comprehensive treatment programs and clinical research.
Key words: chronic obstructive pulmonary disease; coronary artery disease; heart-lung correlation; zongqi; phlegm; stasis; toxins
臨床上,慢性阻塞性肺疾病(chronic obstructive pulmonary disease,COPD)和冠心病(coronary artery disease,CAD)常相互影响而合并存在。COPD与CAD风险增加相关[1],也与心血管原因的住院率增加相关,且独立于先前存在的心血管疾病(CVD)风险因子[2],表明在COPD患者中CAD的发病率明显高于年龄和风险因子匹配的对照人群。但COPD患者中CAD常常漏诊[3-5]。
根据临床常见的心肺共病现象,为了更好理解其病理生理关系,Ukena C等[6]提出“心肺一体”假说,认为共同的风险因子产生了全身炎症反应过程,这导致了动脉粥样硬化性疾病和COPD的进展。炎症在心血管和肺部疾病的发病机制中发挥了主要作用,是“共同的温床”。《内经》对此就已提出了心肺疾病的相关性,《素问·咳论篇》曰:“心咳之状,咳则心痛,喉中介介如梗状,甚则咽肿,喉痹。”心肺脏器相邻,经络相连,阴阳相应,生理相关,病理相系,故而心肺之间是密切联系的。然而,以“心肺相关”解释COPD合并CAD的中医发病机制显得过于笼统。基于COPD合并CAD的共同病理生理机制——慢性低程度全身炎症反应,而炎症又是具有血管系统的活体组织对损伤因子所发生的防御反应,笔者提出宗气亏虚、营卫交会生化紊乱、痰瘀毒互结是COPD合并CAD的中医病机。……
