Long-term outcomes of percutaneous coronary intervention in patients with chronic obstructive pulmonary disease: a 13-year nationwide cohort study

Chronic obstructive pulmonary disease (COPD) is associated with increased risk of coronary atherosclerosis. However, its impact on the long-term outcomes in patients undergoing percutaneous coronary intervention (PCI) has not been described. Using the National Health Insurance Research Database of Taiwan, we identified 215275 adult patients who underwent first-time PCI between 2000 and 2012. Among them, the outcomes of patients with COPD (n = 24900) and without COPD (n = 190375) were compared. Baseline demographics and 13-year overall mortality and adverse cardiac outcomes after PCI (i.e., ischemic events, repeat revascularization and major adverse cardiac events (MACE)) in association with COPD were analyzed. Patients with COPD were older (mean age 72.7 vs 64.4 years, P
