Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="resp12295-sec-0001" sec-type="section"> <title>Background and objective</title> <p>Systemic inflammation plays an important role in both chronic obstructive pulmonary disease (COPD) and coronary artery disease (CAD). The purpose of the present study was to assess the association of high‐sensitivity C‐reactive protein (hs‐CRP), a biomarker of systemic inflammation, with in‐hospital outcomes in patients with COPD undergoing percutaneous coronary intervention (PCI).</p> </sec> <sec id="resp12295-sec-0002" sec-type="section"> <title>Methods</title> <p>A total of 378 patients with COPD who were treated with PCI from January 2007 through January 2012, were divided into two groups according to hs‐CRP level at admission. Demographics, clinical, angiographic data and in‐hospital outcomes were compared.</p> </sec> <sec id="resp12295-sec-0003" sec-type="section"> <title>Results</title> <p>Patients with elevated hs‐CRP (≥3 mg/L) were more likely to be female and current smokers, had more severe airflow limitation, more hypertension, diabetes and cardiac dysfunction and had increased incidence of three‐vessel disease and more type C lesions. Subjects with elevated hs‐CRP were also less likely to have been prescribed with statins and B‐blockers, perhaps. Rate of in‐hospital composite major adverse cardiovascular events (MACEs) was higher (15.5% vs 8.2%, <italic>P</italic> = 0.041) and hospital stay was longer (8.2 ± 2.0 vs 7.5 ± 1.7 days, <italic>P</italic> < 0. 001) in patients with elevated hs‐CRP. A combined analysis of MACE on the basis of airflow limitation and hs‐CRP showed an exaggerated hazard ratio in the presence of both severe airflow limitation and elevated hs‐CRP. In a multivariate analysis, elevated periprocedural hs‐CRP was independently related with MACEs and hospital stay.</p> </sec> <sec id="resp12295-sec-0004" sec-type="section"> <title>Conclusions</title> <p>Elevated periprocedural hs‐CRP is independently and additively related with increased incidence of in‐hospital adverse outcomes in COPD patients undergoing PCI.</p> </sec> </abstract>
