A prospective, multicenter derivation of a biomarker panel to assess risk of organ dysfunction, shock, and death in emergency department patients with suspected sepsis.

Abstract: Objective: To define a biomarker panel to predict organ dysfunction, shock, and in-hospital mortality in emergency department (ED) patients with suspected sepsis. Design: Prospective observational study. Setting: EDs of ten academic medical centers. Patients: There were 971 patients enrolled. Inclusion criteria: 1) ED patients age > 18; 2) suspected infection or a serum lactate level > 2.5 mmol/L; and 3) two or more systemic inflammatory response syndrome criteria. Exclusion criteria: pregnancy, do-not-resuscitate status, or cardiac arrest. Measurements and Main Results: Nine biomarkers were assayed from blood draws obtained on ED presentation. Multivariable logistic regression was used to identify an optimal combination of biomarkers to create a panel. The derived formula for weighting biomarker values was used to calculate a "sepsis score," which was the predicted probability of the primary outcome of severe sepsis (sepsis plus organ dysfunction) within 72 hrs. We also assessed the ability of the sepsis score to predict secondary outcome measures of septic shock within 72 hrs and in-hospital mortality. The overall rates of each outcome were severe sepsis, 52%; septic shock, 39%; and in-hospital mortality 7%. Among the nine biomarkers tested, the optimal 3-marker panel was neutrophil gelatinase-associated lipocalin, protein C, and interleukin-1 receptor antagonist. The area under the curve for the accuracy of the sepsis score derived from these three biomarkers was 0.80 for severe sepsis, 0.77 for septic shock, and 0.79 for death. When included in multivariate models with clinical variables, the sepsis score remained highly significant (p < 0.001) for all the three outcomes. Conclusions: A biomarker panel of neutrophil gelatinase-associated lipocalin, interleukin-1 ra, and Protein C was predictive of severe sepsis, septic shock, and death in ED patients with suspected sepsis. Further study is warranted to prospectively validate the clinical utility of these biomarkers and the sepsis score in risk-stratifying patients with suspected sepsis.

Contrast-induced acute kidney injury after primary percutaneous coronary intervention: results from the HORIZONS-AMI substudy.

Abstract: Aim We sought to examine the short- and long-term outcomes of patients who developed contrast-induced acute kidney injury (CI-AKI; defined as an increase in serum creatinine of ≥0.5 mg/dL or a 25% relative rise within 48 h after contrast exposure) from the large-scale HORIZONS-AMI trial. Methods and results Multivariable analyses were used to identify predictors of CI-AKI, as well predictors of the primary and secondary endpoints. The incidence of CI-AKI in this cohort of ST-segment elevation myocardial infarction (STEMI) patients was 16.1% (479/2968). Predictors of CI-AKI were contrast volume, white blood cell count, left anterior descending infarct-related artery, age, anaemia, creatinine clearance <60 mL/min, and history of congestive heart failure. Patients with CI-AKI had higher rates of net adverse clinical events [NACE; a combination of major bleeding or composite major adverse cardiac events (MACE; consisting of death, reinfarction, target vessel revascularization for ischaemia, or stroke)] at 30 days (22.0 vs. 9.3%; P < 0.0001) and 3 years (40.3 vs. 24.6%; P < 0.0001). They also had higher rates of mortality at 30 days (8.0 vs. 0.9%; P < 0.0001) and 3 years (16.2 vs. 4.5%; P < 0.0001). Multivariable analysis confirmed CI-AKI as an independent predictor of NACE [hazard ratio ([HR), 1.53; 95% confidence interval (CI), 1.23–1.90; P = 0.0001], MACE (HR, 1.56; 95% CI, 1.23–1.98; P = 0.0002), non-coronary artery bypass grafting major bleeding (HR, 2.07; 95% CI, 1.57–2.73; P < 0.0001), and mortality (HR, 1.80; 95% CI, 1.19–2.73; P = 0.005) at 3-year follow-up. Conclusion Contrast-induced acute kidney injury is associated with poor short- and long-term outcomes after primary percutaneous coronary intervention in STEMI.

Prognostic impact of a chronic total occlusion in a non-infarct-related artery in patients with ST-segment elevation myocardial infarction: 3-year results from the HORIZONS-AMI trial.

Abstract: Aims We sought to investigate the impact of multivessel disease (MVD) with and without a chronic total occlusion (CTO) in a non-infarct-related artery (IRA) on mortality in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Methods and results In the HORIZONS-AMI trial, of 3283 patients undergoing primary PCI, 1524 patients (46.4%) had single-vessel disease (SVD), 1477 (45.0%) had MVD without a CTO, and 283 (8.6%) had MVD with a CTO in a non-IRA. Compared with SVD patients and MVD patients without a CTO, patients with a non-IRA CTO were significantly less likely to achieve post-procedural TIMI 3 flow ( P = 0.0003), more often had absent myocardial blush ( P = 0.0002), and less frequently achieved complete ST-segment resolution ( P = 0.0001). By multivariable analysis, MVD with CTO in a non-IRA was an independent predictor of both 0- to 30-day mortality [hazard ratio (HR) 2.88, 95% confidence interval (CI) 1.41–5.88, P = 0.004] and 30-day to 3-year mortality (HR 1.98, 95% CI 1.19–3.29, P = 0.009), while MVD without a CTO was a significant predictor for 0- to 30-day mortality (HR 2.20, 95% CI 1.00–3.06, P = 0.049) but not late mortality. Conclusion In patients with STEMI undergoing primary PCI in the HORIZONS-AMI trial, MVD with or without a CTO in a non-IRA was an independent predictor of early mortality. The presence of a CTO in a non-IRA was also an independent predictor of increased late mortality to 3 years.
