Figure 1 Patients with COPD suffer from worse outcomes after percutaneous coronary intervention (PCI) than patients without COPD. Shown are all-cause mortality (A), cardiac mortality (B), and occurrence of myocardial infarction (C) after the index PCI.

Figure 2 Multivariate proportional hazard model showing COPD as an independent risk factor for various adverse outcomes in patients after percutaneous coronary intervention. DES = drug-eluting stent; LV EF = left ventricular ejection fraction; MI = myocardial infarction. See Figure 1 for expansion of other abbreviation.

Figure 3 Survival analysis of patients after PCI stratified based on the presence and severity of COPD. Patients without COPD are shown as “no COPD”; patients with available pulmonary function test results are classified according to the following standard clinical definitions: very severe COPD, an FEV1/FVC ratio ≤ 70 and an FEV1 ≤ 30% predicted; severe COPD, an FEV1/FVC ratio ≤ 70 and an FEV1 between 30% and 50% predicted; and mild-to-moderate COPD, an FEV1/FVC ratio ≤ 70 and an FEV1 ≤ 50% predicted. Patients with an FEV1/FVC ratio > 70 are classified as such irrespective of their FEV1. See Figure 1 for expansion of abbreviation.

Figure 4 Survival analysis of patients with COPD with an abnormal, nonspecific pattern on pulmonary function tests (FEV1/FVC ratio > 70) stratified by FEV1 > 80% predicted and an FEV1 < 80% predicted.
