Enriquez et al analyzed data from the NHLBI Dynamic Registry, comparing 860 people with COPD to 10,048 without who underwent percutaneous coronary intervention between 1999-2006. Their main findings: COPD patients were sicker and had worse outcomes. Demographically, they had a higher rate of diabetes, slightly more lesions (3.2 vs. 3.0), and slightly lower ejection fractions. Only half were prescribed beta blockers at discharge (compared to 76% of non-COPDers). After attempted adjustment for confounders, people with COPD had a one-year hazard ratio of death of 1.30 and of revascularization, 1.22 (significant).
