Increased plasma levels of neuron-specific enolase (NSE) are related to damage of neurons and neuroendocrine cells. We aimed to investigate elevation of NSE after elective percutaneous coronary intervention (PCI) on the prediction of silent cerebral infarct (SCI). Study population consisted of 2 groups of patients. Group 1 included 92 consecutive patients with normal coronary angiograms, whereas group 2 consisted of 89 patients who underwent elective coronary stenting. NSE levels were studied before and 12 hours after the procedure. Elevation of >0.12 mu g/L was considered as SCI. Forty-seven of 181 study patients (26%) had SCI after the procedure. NSE elevation was significantly more prevalent in patients with PCI than that of controls. Elevation of NSE was observed in 42% of patients who underwent elective PCI (n = 37) and 11% of the normal coronary artery group (n = 10) (p <0.001). The incidence of SCI was higher in active smokers and patients who had history of myocardial infarction (MI) (55% vs 10%, p <0.001 for active smokers and 40% vs 8%, p <0.001 for history of MI, respectively). Multivariate analysis demonstrated history of smoking (odds ratio [OR] 9.9; 95% confidence interval [CI] 33 to 26.9; p <0.001) and previous MI (OR 4.4; 95% CI 1.7 to 11.4; p = 0.01) as independent predictors of SCI. For patients who underwent elective PCI, NSE levels after procedure increases. Invasive coronary procedures have risk of SCIs, even in patients with normal coronary arteries. In conclusion, increased diagnosis of SCIs might improve understanding of their relation with invasive cardiac procedures, facilitate to prevent occurrence of silent microemboli and decrease the risk of adverse neurologic events.
