Frequency of Cardiac Death and Stent Thrombosis in Patients With Chronic Obstructive Pulmonary Disease Undergoing Percutaneous Coronary Intervention (from the BASKET-PROVE I and II Trials)
Research output: Contribution to journal › Journal article › Research › peer-review
Chronic obstructive pulmonary disease (COPD) is associated with long-term all-cause death after percutaneous coronary intervention with bare-metal stents. Regarding other outcomes, previous studies have shown conflicting results and the impact of drug-eluting stent (DES) in this population is not well known. We analyzed 4,605 patients who underwent percutaneous coronary intervention with bare-metal stents (33.1%) or DES (66.9%) from the Basel Stent Kosten-Effektivitats Trial-Prospective Validation Examination trials I and II. COPD patients (n = 283, 6.1%), were older and had more frequently a smoking or cardiovascular event history. At 2-year follow-up, cumulative event rates for patients with versus without COPD were the following: major adverse cardiac events (MACE: composite of cardiac death, nonfatal myocardial infarction, and target vessel revascularization): 15.2% versus 8.1% (p <0.001); all-cause death: 11.7% versus 2.4% (p <0.001); cardiac death: 5.7% versus 1.2% (p <0.001); myocardial infarction: 3.5% versus 1.9% (p = 0.045); definite/probable/possible stent thrombosis: 2.5% versus 0.9% (p = 0.01); and major bleeding: 4.2% versus 2.1% (p = 0.014). After adjusting for confounders including smoking status, COPD remained an independent predictor for MACE (hazard ratio [HR] 1.80, 95% confidence interval [CI] 1.31 to 2.49), all-cause death (HR 3.62, 95% CI 2.41 to 5.45), cardiac death (HR 3.12, 95% CI 1.74 to 5.60), and stent thrombosis (HR 2.39, 95% CI 1.03 to 5.54). We did not find evidence of an interaction between COPD and DES implantation (p for interaction = 0.29) for MACE. In conclusion, COPD is associated with increased 2-year rates of all-cause death, cardiac death, and stent thrombosis after stent implantation. DES use appears to be beneficial also in patients with COPD.
