AbstractHigh-sensitivity cardiac troponin I (hs-cTnI) is a widely used biomarker to identify ischemic chest pain in the Emergency Department (ED), but the clinical impact on emergency coronary artery bypass grafting (eCABG) remains undetermined. We aimed to evaluate the clinical impact of hs-cTnI measured at the ED by comparing outcomes of eCABG in patients with non–ST-segment–elevation acute coronary syndrome (NSTE-ACS) which comprises unstable angina (UA) and non–ST-segment–elevation myocardial infarction (NSTEMI). From January 2012 to March 2016, 242 patients undergoing eCABG were grouped according to serum hs-cTnI level in the ED. The primary endpoint was major cardiovascular cerebral event (MACCE) defined as a composite of all-cause death, myocardial infarction, repeat revascularization, and stroke. The incidence of each MACCE composite, in addition to postoperative complications such as acute kidney injury, reoperation, atrial fibrillation, and hospital stay duration were also compared. Patients were divided into two groups: UA [<0.04 ng/mL, n = 102] and NSTEMI [≥0.04 ng/mL, n = 140]. The incidence of MACCE did not differ between the two groups. Postoperative acute kidney injury was more frequent in the NSTEMI group after adjusting for confounding factors (6.9% vs. 23.6%; odds ratio, 2.76; 95% confidence interval, 1.09–6.99; p-value = 0.032). In-hospital stay was also longer in the NSTEMI group (9.0 days vs. 15.4 days, p-value = 0.008). ECABG for UA and NSTEMI patients showed comparable outcomes, but hs-cTnI elevation at the ED may be associated with immediate postoperative complications.

The Impact

Objectives: We evaluated the impact of prasugrel pretreatment and timing of coronary artery bypass grafting (CABG) on clinical outcomes of patients with non-ST-segment elevation myocardial infarction (NSTEMI) undergoing CABG based on data from ACCOAST. Methods: We evaluated the impact of troponin, prasugrel pretreatment and CABG timing on clinical outcomes of NSTEMI patients undergoing CABG through 30 days from ACCOAST. Results: CABG patients versus PCI or medically managed patients were more often male, diabetic, had peripheral arterial disease and a higher GRACE score. By randomization assignment, 157 patients received a 30-mg loading-dose of prasugrel before CABG; 157 patients did not. CABG patients were grouped by tertiles of time from randomization to CABG; baseline characteristics in the Table. Patients in the lowest tertile had significantly more events (cardiovascular death, MI, stroke, urgent revascularization or glycoprotein IIb/IIIa bailout) and all TIMI major bleeds than those in the other 2 groups (p<0.045, p<0.002 respectively), but the patients in the higher 2 groups were not significantly different from each other. No difference was detected in all cause death among the 3 groups (p>0.39). A multivariate model evaluated 5 possible predictors of the composite endpoint of all cause death, MI, stroke and TIMI major bleeding. Time from randomization to CABG (HR 0.84 for each 1 hour of delay), left main disease presence (HR 1.76), and region of enrollment (Eastern Europe vs other, HR 3.83) were significant predictors but not prasugrel pretreatment or baseline troponin level ≥3xULN. Conclusions: In this group of high-risk patients presenting with NSTEMI, early surgical revascularization carried an increased risk of bleeding and ischemic complications, without impact on all-cause mortality. No impact of baseline troponin or prasugrel pretreatment (important factors influencing time of CABG) on clinical outcomes was confirmed.
