Markers of myocardial injury, such as creatine kinase-myocardial band (CK-MB) mass, are elevated in up to 30% of patients undergoing percutaneous coronary intervention (PCI) with stent deployment. This elevation represents myocardial injury that can impact the patient in the long term, including the risk of death. Sevoflurane, an inhaled anesthetic, may have cardioprotective properties that benefit patients undergoing PCI. The primary objective was to compare serum CK-MB mass raise in patients who received sevoflurane to those who received a placebo prior to PCI. We enrolled patients with coronary artery disease who were eligible for PCI in a randomized (1:1), double-blind, placebo-controlled trial; patients having experienced acute myocardial infarction within 72 hours and those with saphenous vein graft stenting were excluded. Patients (n = 1254) were randomized to receive sevoflurane (2% inspired fraction) or placebo (oxygen alone) for 30 minutes prior to PCI. Additionally, we compared substantial elevations in CK-MB mass (defined as >5x the upper limit of normal), length of stay in the intensive care unit and in-hospital, and 1-year mortality. Sevoflurane was unable to promote cardioprotection, as determined by CK-MB mass levels (sevoflurane group: 2.52 ± 9.64; control group: 1.84 ± 8.58; P=.32). No effect was noticed on the reduction among patients who (AQ: with?) increase (AQ: increased?) marker levels (prevalence of increase in CK-MB mass greater than the upper limit of normality was 30.8% in the sevoflurane group and 28.9% in the control group; P=.33; 4.6% vs 3.1%, respectively, for increases 5x above the upper limit of normality [P=.21]). Sevoflurane failed to reduce myocardial injury after PCI. Therefore, its usage should not be routinely recommended.
