Interventional Cardiology 275 9 Years of Left Main Stem Coronary Stenting at Christchurch Hospital S. Aldous ∗ , J. Blake, J. Elliott, D. McClean, D. Smyth Christchurch Hospital, New Zealand Background: It is conventional to treat left main stem (LMS) disease with coronary artery bypass surgery (CABG). Recently studies such as SYNTAX have suggested that stenting for LMS disease with drug eluting stents may be an appealing alternative to surgical revascularisation. Methods: A retrospective audit was conducted of all 89 procedures involving unprotected LMS stenting from 2001 to the present. Results: The mean age was 69 ± 12 years. The occurrence of major adverse events during follow-up is reported below: Number (%)

Conclusion: Those presenting with cardiogenic shock or acute myocardial infarction (AMI) due to a LMS lesion have a guarded prognosis although advances in percutaneous coronary intervention (PCI) techniques and second generation stents since 2004 have lead to an improved outcome. The results for stable and unstable coronary syndromes are encouraging, suggesting that in certain subsets of LMS disease PCI may ultimately offer an alternative to CABG. doi:10.1016/j.hlc.2010.06.942 276 A Comparison of Fluoroscopy Time and Serum Creatine Kinase as Predictors of Long-term Outcome after Percutaneous Coronary Intervention G. Starmer ∗ , K. Haladyn, V. Indrajith, K. Bhuiyan, S. Crown, R. Lim Princess Alexandra Hospital Brisbane, University of Queensland, Australia Background: Prolonged fluoroscopy time (FT) is a promising marker of adverse long-term outcome following percutaneous coronary intervention (PCI). FT and serum creatine kinase (CK) both reflect procedural and patient complexity, operator skills and any acute proce-

dural complications, all of which impact on prognosis. FT is routinely recorded and CK is easily measured, but it is not clear which is better at predicting major clinical events after contemporary PCI. Objective: We therefore compared the ability of FT and CK in predicting long-term all-cause mortality and the need for coronary bypass grafting (CABG) after PCI. Methods: We followed up 398 consecutive patients (mean age 61; range 33–86) at our tertiary interventional centre who had PCI with stenting then CK measurement the following day. Patients undergoing PCI for acute myocardial infarction and those with elevated CK (≥150 U/L) at the time of PCI were excluded. Patients were stratified according to FT (
