AimsGiven the anecdotal reports and case series suggesting that drug-eluting coronary stents [DES] may be still vulnerable to coronary thrombosis after six months, we sought to assess this risk in patients undergoing non-cardiac surgery six months after stenting.Methods And ResultsLinking the Rabin Medical Centre interventional cardiology database with its non-cardiac surgical database, we identified 78 patients who underwent DES placement and subsequently [after six months] had noncardiac surgery [15-vascular, 37- abdominal and genitourinary and 26-others, excluding ophthalmic surgery]. Outcome measures included 30-day rate of postoperative myocardial infarction (MI), DES-related thrombosis, and cardiac mortality. Major adverse cardiac events [death and non-fatal MI] occurred in 6 (7.7%) patients including 2 cardiac deaths (2.6%), 4 (5.1%) non-fatal myocardial infarctions (MIs). Two patients (2.6%) sustained stent thrombosis [one patient had 'definite' and one 'probable' stent thrombosis]. All MIs [including stent thrombosis] occurred in the vascular and abdominal surgery group. Two of the MIs events occurred while the patients were on dual antiplatelet agents.In ConclusionsPerioperative cardiac events during non cardiac surgery after six months of DES deployment still occur. These cardiac complications [not entirely prevented by continued dual antiplatelet agents] remain a matter of diagnostic and therapeutic challenge and concern.Copyright 2009 Wiley-Liss, Inc.
