title: Effect of chronic obstructive pulmonary disease on survival of patients with coronary heart disease having percutaneous coronary intervention.
abstract: There are limited data regarding the effect of chronic obstructive pulmonary disease (COPD) on the survival of patients with coronary artery disease. Prospectively developed and collected data elements on 4,284 consecutive patients who underwent percutaneous coronary intervention in 3 hospitals in 1998 and 1999 were pooled and analyzed. In-hospital major adverse cardiac outcomes were not different between groups. At 3-year follow-up, mortality for patients with COPD was 21% versus 9% for patients without COPD (log-rank p < 0.001). COPD was independently associated with a 2-fold increase in the hazard of long-term mortality (hazard ratio 2.146, 95% confidence interval 1.525 to 3.021, p < 0.001).
