Prior coronary stent does not exclude major pulmonary resection regardless of antiplatelet therapy.

ABSTRACT

PURPOSE: We assessed the safety of general thoracic surgery in patients with prior coronary stents undergoing lung resection, based on differences in perioperative antiplatelet therapy management. METHODS: We retrospectively examined 150 patients with coronary artery stents who underwent pulmonary resection between July 2009 and July 2018. The impact of the antiplatelet agent on thoracic surgery safety was assessed by comparing perioperative outcomes, including major adverse cardiac and cerebrovascular events, among the discontinued antiplatelet therapy (group D), heparin bridging (group H), and continuous antiplatelet therapy (group C) groups. RESULTS: Groups D, H, and C included twenty-four, eighty-four, and forty-two patients, respectively. Second-generation drug-eluting stents were used in > 50% of the patients. No significant differences were found in the estimated blood loss, transfusion rate, or operative duration. Major adverse cardiac and cerebrovascular events occurred in four (2.7%) patients, which was comparable among the groups. In group H, postoperative heart failure and transient ischemic attack with stroke occurred in one patient each. Major bleeding occurred in two (4.7%) patients in group C. CONCLUSIONS: Pulmonary resection surgical outcomes in patients with coronary artery stents were feasible regardless of antiplatelet therapy continuation. However, discontinuing dual-antiplatelet or single-antiplatelet therapy in such patients may be reasonable because this generation of drug-eluting stents has a higher safety profile than bare-metal and first-generation drug-eluting stents.
