Randomized Controlled Trial Comparative Study
Serum matrix metalloproteinases in patients resuscitated from cardiac arrest. The association with therapeutic hypothermia.
To study the systemic levels of matrix metalloproteinases (MMP) -7, -8 and -9 and their inhibitor TIMP-1 in cardiac arrest patients and the association with mild therapeutic hypothermia treatment on the serum concentration of these enzymes. ⋯ We demonstrated that the systemic levels of MMP-7, -8 and -9 but not TIMP-1 are elevated in cardiac arrest patients in the 48 h post-resuscitation period relative to the healthy controls. Patients who received therapeutic hypothermia had lower MMP-9 levels compared to non-hypothermia treated patients, which generates hypothesis about attenuation of inflammatory response by hypothermia treatment.

Comparative Study
Circulating cell-free DNA levels correlate with postresuscitation survival rates in out-of-hospital cardiac arrest patients.
Early prediction of prognosis is helpful in cardiac arrest patients. Plasma cell-free DNA, which increases rapidly after cell death, is a novel biomarker for the prognosis of critical ill patients. Changes in the plasma cell-free DNA level and its role for the early prognosis of cardiac arrest patients remain unclear. ⋯ The optimal cutoff value of plasma cell-free DNA for predicting survival-to-discharge was 1,170 g.e./mL by ROC curve analysis (area under curve 0.752, p=0.010). A plasma cell-free DNA level higher than 1,170 g.e./mL and was an independent predictor for in-hospital mortality by multiple logistic regression analysis (adjusted odds ratio of 12.35, p=0.023) and was also associated with higher 90 day mortality (p=0.021 by log-rank test). In conclusion, the plasma cell-free DNA level increases during the early post-cardiac arrest phase and can be an early prognostic factor for OHCA patients.
