Abstract: BACKGROUND: Many patients requiring lung cancer resection have concomitant coronary artery disease. Preoperative coronary artery stenting has been associated with increased risk of cardiac events after noncardiac surgery. Our aim was to determine the incidence of major adverse cardiac events (MACE) in patients undergoing pulmonary resection for lung cancer after percutaneous coronary stenting. METHODS: This study uses Surveillance, Epidemiology, and End Results-Medicare data (1998 to 2005). Patients undergoing lung cancer resection within 1 year after coronary stenting were compared with patients without preoperative coronary intervention. The incidence and predictors of MACE within 30 days after surgery were determined. RESULTS: Five hundred nineteen patients underwent lung cancer resection after coronary stenting (stent), and 21,892 patients underwent lung cancer resection without a preceding coronary intervention (no stent). The stent group had higher comorbidity scores (p<0.0001) and more males (66% versus 50%; p<0.0001). There were no differences in age (74 versus 74 years), tumor size (33.7 versus 33.6 mm), stage (53% versus 54% stage I), and resections of lobectomy or greater (83% versus 80%) between stent and no-stent groups (all p>0.05). Thirty-day MACE and mortality rates were 9.3% and 7.7% in the stent group and 4.9% and 4.6% in the no-stent group (both p<0.0001). Multivariable predictors of MACE were coronary stent, age, male sex, comorbidity score, tumor size, and stage. CONCLUSIONS: Patients undergoing lung cancer surgery within 1 year of coronary stenting are at high risk for perioperative MACE. The presence of a coronary stent should be an important component of risk assessment before resection for lung cancer.
