Revascularization Strategies in Patients with Coronary Artery Disease and Chronic Obstructive Lung Disease.

Overview

PURPOSE OF REVIEW: This paper assesses recent literature on the impact of chronic obstructive pulmonary disease (COPD) in patients with coronary artery disease (CAD) undergoing revascularization. Specifically, to determine if there is an optimal revascularization strategy for this patient population, and if there are other modalities to assess the risks. RECENT FINDINGS: There are limited new data in the last year addressing this clinical question. Recently there have been a series of studies which reinforced that COPD is a key independent risk factor for adverse outcomes after revascularization. There is no optimal revascularization strategy; however, there was a nonsignificant signal of potential benefit with percutaneous coronary intervention (PCI) with short-term outcomes in the SYNTAXES trial. Currently, pulmonary function tests (PFT) are limited in clarifying risk assessments prior to revascularization, and there are investigations into the use of biomarkers to provide further insight into this increased risk of adverse outcomes in patients with COPD. SUMMARY: COPD is a key risk factor for poor outcomes in patients requiring revascularization. More investigations are needed to determine the optimum revascularization strategy.
