    • Further characterization of the post-cardiac arrest syndrome (PCAS) is essential to better understand the mechanisms resulting in injury and death. We investigated serial serum concentrations of the stress hormone c-terminal provasopressin (CT-proAVP or copeptin), the cardiac biomarker MR-proANP and a biomarker of oxidation injury, Peroxiredoxin 4 (Prx4) in patients treated with mild hypothermia (MHT) after cardiac arrest, and studied their association to the PCAS and long-term outcome.

  • Procalcitonin after cardiac arrest - An indicator of severity of illness, ischemia-reperfusion injury and outcome.
  • 2013
  • Ingår i: Resuscitation. - : Elsevier BV. - 1873-1570 .- 0300-9572. ; 84:6, s. 782-787

    • AIM: To investigate serial serum concentrations of procalcitonin (PCT) and C-reactive protein (CRP) in patients treated with mild hypothermia after cardiac arrest, and to study their association to severe infections, post cardiac arrest syndrome (PCAS) and long-term outcome. METHODS: Serum samples from cardiac arrest patients treated with mild hypothermia were collected serially at admission, 2, 6, 12, 24, 36, 48 and 72h after cardiac arrest. PCT and CRP concentrations were determined and tested for association with three definitions of infection, two surrogate markers of PCAS (circulation-SOFA and time to return of spontaneous circulation (ROSC)) and cerebral performance category (CPC) at six months. RESULTS: Eighty-four patients were included. PCT displayed an earlier release pattern than CRP with a significant increase within 2h, increasing further at 6h and onwards in patients with poor outcome. CRP increased later and continued to rise during the study period. PCT was strongly associated with circulation-SOFA and time to ROSC, and predicted a poor neurologic outcome with high accuracy (area under the receiver operating characteristic curve of 0.88, 0.86 and 0.87 at 12, 24 and 48h respectively). No association of PCT or CRP to infection was observed. CONCLUSION: Our results suggest that PCT is released early after resuscitation following cardiac arrest, is associated with markers of PCAS but not with infection, and is an accurate predictor of poor outcome. Validation of these findings in larger studies is warranted.

  • Heparin-binding protein: An early indicator of critical illness and predictor of outcome in cardiac arrest.
  • 2013
  • Ingår i: Resuscitation. - : Elsevier BV. - 1873-1570 .- 0300-9572. ; 84:7, s. 935-939
  • Tidskriftsartikel (refereegranskat)abstract
    • AIM: To investigate plasma levels of the neutrophil-borne heparin-binding protein (HBP) in patients with induced hypothermia after cardiac arrest (CA), and to study any association to severity of organ failure, incidence of infection and neurological outcome. METHODS: This study included 84 patients with CA of mixed origin who were treated with hypothermia. Plasma samples from 7 time points during the first 72h after return of spontaneous circulation (ROSC) were collected and analyzed for HBP with an ELISA. Outcomes were dichotomized: a cerebral performance category scale (CPC) of 1-2 at 6 months follow-up was considered a good outcome, a CPC of 3-5, a poor outcome. Patient data, including APACHE II and SOFA-scores were retrieved from the computerized system for quality assurance for intensive care. RESULTS: At 6h and 12h after CA, plasma levels of HBP were significantly higher among patients with a poor outcome. A receiver operated characteristics (ROC)-analysis yielded respective areas under curve (AUC) values of 0.68 and 0.70. This was similar to APACHE II and SOFA-score AUC values. There was a significant correlation between early elevated HBP-values and time to ROSC. HBP-levels were not higher in patients with infections at any time. CONCLUSIONS: Elevated HBP is an early indicator of organ failure and poor neurological outcome after CA, independent of microbial infection, and should be further evaluated in prospective trials. The temporal profile of HBP is suggestive of a role in the pathogenesis of critical illness after CA.

  • Safety, Feasibility, and Outcomes of Induced Hypothermia Therapy Following In-Hospital Cardiac Arrest-Evaluation of a Large Prospective Registry
  • 2014
  • Ingår i: Critical Care Medicine. - 0090-3493 .- 1530-0293. ; 42:12, s. 2537-2545

    • Objectives: Despite a lack of randomized trials, practice guidelines recommend that mild induced hypothermia be considered for comatose survivors of in-hospital cardiac arrest. This study describes the safety, feasibility, and outcomes of mild induced hypothermia treatment following in-hospital cardiac arrest. Design: Prospective, observational, registry-based study. Setting: Forty-six critical care facilities in eight countries in Europe and the United States reporting in the Hypothermia Network Registry and the International Cardiac Arrest Registry. Patients: A total of 663 patients with in-hospital cardiac arrest and treated with mild induced hypothermia were included between January 2004 and February 2012. Interventions: None. Measurements and Main Results: A cerebral performance category of 1 or 2 was considered a good outcome. At hospital discharge 41% of patients had a good outcome. At median 6-month follow-up, 34% had a good outcome. Among in-hospital deaths, 52% were of cardiac causes and 44% of cerebral cause. A higher initial body temperature was associated with reduced odds of a good outcome (odds ratio, 0.79; 95% CI, 0.68-0.92). Adverse events were common; bleeding requiring transfusion (odds ratio, 0.56; 95% CI, 0.31-1.00) and sepsis (odds ratio, 0.52; 95% CI, 0.30-0.91) were associated with reduced odds for a good outcome. Conclusions: In this registry study of an in-hospital cardiac arrest population treated with mild induced hypothermia, we found a 41% good outcome at hospital discharge and 34% at follow-up. Infectious complications occurred in 43% of cases, and 11% of patients required a transfusion for bleeding. The majority of deaths were of cardiac origin.

  • Platelet aggregation and clot formation in comatose survivors of cardiac arrest treated with induced hypothermia and dual platelet inhibition with aspirin and ticagrelor; a prospective observational study
  • 2014
  • Ingår i: Critical Care. - : Springer Science and Business Media LLC. - 1364-8535. ; 18:5
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: We conducted a prospective observational study in cardiac arrest survivors treated with mild induced hypothermia, evaluating different platelet function tests at hypo-and normothermia. We also investigated the relation between gastric emptying and vasodilator stimulated phosphoprotein (VASP). Methods: Comatose survivors of out of hospital cardiac arrest were included and divided into two groups, depending on whether dual platelet inhibition with peroral ticagrelor and aspirin was given or not. The first blood samples (T1) were collected 12-24 hours after reaching target temperature (33 degrees C) and were compared to blood samples collected 12-28 hours after reaching normothermia (37 degrees C) (T2) within each group. All samples were analysed by Sonoclot viscoelasticity, flow cytometry based VASP and with multiple electrode aggregometry, Multiplate (R); adenosine diphosphate (ADP), collagen (COL), thrombin receptor agonist peptide (TRAP) and arachidonic acid (ASPI). Sonoclot and Multiplate (R) instruments were set on in vivo temperatures. Gastric secretion from the nasogastric tube was measured to assess absorption of per orally administered antiplatelet drugs. Differences between T1 and T2 within each group were calculated using Wilcoxon matched pairs signed test. Significance levels were set at P < 0.01. Results: In total, 23 patients were included. In patients with dual platelet inhibition (n = 14) Multiplate (R)-analyses showed no changes in ADP stimulated platelets. COL, TRAP and ASPI aggregations were higher at T2 compared to T1. Sonoclot-analyses showed that activated clotting time (ACT) was unchanged but both clot rate (CR) and platelet function (PF) were higher at T2 compared to T1. VASP decreased from 53 +/- 28(T1) to 24 +/- 22(T2), (P < 0.001). The average volume of gastric secretion aspirated before T1 correlated well with VASP (T1), r = 0.81 (P < 0.001). In patients with no platelet inhibition, (n = 9) similar changes between T1 and T2 were seen as in patients with dual platelet inhibition while VASP was unchanged. Conclusions: We have demonstrated increased platelet aggregation and strengthened clot formation over time in out of hospital cardiac arrest patients treated with hypothermia. In patients on oral dual platelet inhibition, the effect of ticagrelor was delayed, probably due to slow gastric emptying.
