All endpoints were adjudicated

All endpoints were adjudicated Selleck JIB04 by a blinded Clinical End Points Committee. Results: The median catalytic iron level was significantly higher in those who died, 0.45 mu mol/L (0.37,

0.57), compared with survivors, 0.37 mu mol/L (0.31, 0.46; P = 0.016). Catalytic iron was associated with a stepwise increased risk of death, with the highest quartile at an almost 4-fold risk compared with baseline (hazard ratio: 3.94, P = 0.035), which persisted after adjustment for age, diabetes, prior MI, prior congestive heart failure, ST-segment deviation, creatinine clearance, B-type natriuretic peptide, smoking, and Killip class (adjusted hazard ratio: 3.97, P = 0.036). There was no association between catalytic iron and risk of MI, recurrent ischemia, heart failure, or bleeding. Conclusions: Increasing catalytic iron levels were associated with increased all-cause mortality. Although our findings suggest

that catalytic iron is not likely to add to available tools as a routine biomarker for risk stratification of recurrent ischemic events, its association with mortality is intriguing and leaves open the question of whether cardiovascular therapeutics aimed at catalytic iron may MEK162 cell line be useful.

“Background: Anti-infection inhibitor Non-invasive monitoring of cerebral perfusion and oxygen delivery during cardiac arrest is not routinely utilized during cardiac arrest resuscitation. The objective of this study was to investigate the feasibility of using cerebral oximetry during cardiac arrest and to determine the relationship between regional cerebral oxygen saturation (rSO2) with return of spontaneous circulation (ROSC) in shockable (VF/VT) and non-shockable

(PEA/asystole) types of cardiac arrest.

Methods: Cerebral oximetry was applied to 50 in-hospital and out-of-hospital cardiac arrest patients.

Results: Overall, 52% (n=26) achieved ROSC and 48% (n=24) did not achieve ROSC. There was a significant difference in mean +/- SD rSO2% in patients who achieved ROSC compared to those who did not (47.2 +/- 10.7% vs. 31.7 +/- 12.8%, p < 0.0001). This difference was observed during asystole (median rSO2 (IQR) ROSC versus no ROSC: 45.0% (35.1-48.8) vs. 24.9% (20.5-32.9),p<0.002) and PEA (50.6% (46.7-57.5) vs. 31.6% (18.8-43.3), p=0.02), but not in the VF/VT subgroup (43.7% (41.1-54.7) vs. 42.8% (34.9-45.0), p = 0.63). Furthermore, it was noted that no subjects with a mean rSO2 < 30% achieved ROSC.

Conclusions: Cerebral oximetry may have a role as a real-time, non-invasive predictor of ROSC during cardiac arrest.
