Background: Postcardiac arrest patients with a return of spontaneous circulation (ROSC) are critically ill, and high body mass index (BMI) is ascertained to be associated with good prognosis in patients with a critically ill condition. However, the exact mechanism has been unknown. To assess the effectiveness of skeletal muscles in reducing neuronal injury after the initial damage owing to cardiac arrest, we investigated the relationship between estimated lean body mass (LBM) and the prognosis of postcardiac arrest patients. Methods: This retrospective cohort study included adult patients with ROSC after out-of-hospital cardiac arrest from January 2015 to March 2020. The enrolled patients were allocated into good- and poor-outcome groups (cerebral performance category (CPC) scores 1–2 and 3–5, respectively). Estimated LBM was categorized into quartiles. Multivariate regression models were used to evaluate the association between LBM and a good CPC score. The area under the receiver operating characteristic curve (AUROC) was assessed. Results: In total, 155 patients were analyzed (CPC score 1–2 vs. 3–5, n = 70 vs. n = 85). Patients’ age, first monitored rhythm, no-flow time, presumed cause of arrest, BMI, and LBM were different (p < 0.05). Fourth-quartile LBM (≥48.98 kg) was associated with good neurological outcome of postcardiac arrest patients (odds ratio = 4.81, 95% confidence interval (CI), 1.10–25.55, p = 0.04). Initial high LBM was also a predictor of good neurological outcomes (AUROC of multivariate regression model including LBM: 0.918). Conclusions: Initial LBM above 48.98kg is a feasible prognostic factor for good neurological outcomes in postcardiac arrest patients.

Introduction: We have reported previously a favorable neurological outcome by extracorporeal cardiopulmonary resuscitation (ECPR) for out of hospital cardiac arrest. However, effects of ECPR on patients with prolonged pulseless electrical activity (PEA) are unclear. We analyzed etiology of patients with favorable neurological outcomes after ECPR for PEA with witness. Methods: In this single center retrospective study, from January 2007 to May 2018, we identified 68 patients who underwent ECPR for PEA with witness. Of these, 13 patients (19%) had good neurological outcome at 1 month (Glasgow-Pittsburgh Cerebral Performance Category (CPC):1-2, Group G), and 55 patients (81%) had unfavorable neurological outcome (CPC:3-5, Group B). We compared courses of treatment and causes/places of arrests between two groups. Results are expressed as mean ± SD. Results: Patient characteristics were not different between the two groups. Time intervals from collapse to induction of V-A ECMO were also not significantly different (Group G; 46.1 ± 20.2 min vs Group B; 46.8 ± 21.7 min, p=0.92). Ten patients achieved favorable neurological outcome among 39 (26%) with non-cardiac etiology. In cardiac etiology, only 3 of 29 patients (9%) had a good outcome at 1 month (p=0.08). In particular, 5 patients of 10 pulmonary embolism, and 4 of 4 accidental hypothermia responded well to ECPR with a favorable neurological outcome. Additionally, 6 of 13 (46%), who had in hospital cardiac arrest, had good outcome, whereas 7 of 55 (15%) who had out of hospital cardiac arrest, had good outcome (p=0.02). Conclusions: In our small cohort of cardiac arrest patients with pulmonary embolism or accidental hypothermia and PEA with witness, EPCR contributed to favorable neurological outcomes at 1 month.

Background: Studies have suggested that taurine may have neuro- and cardio-protective functions, but there is little research looking at taurine levels in patients after out-of-hospital cardiac arrest (OHCA). Our aim was to evaluate the association of taurine with mortality and neurological deficits in a well-defined cohort of OHCA patients. Methods: We prospectively measured serum taurine concentration in OHCA patients upon admission to the intensive care unit (ICU) of the University Hospital Basel (Switzerland). We analyzed the association of taurine levels and in-hospital mortality (primary endpoint). We further evaluated neurological outcomes assessed by the cerebral performance category scale. We calculated logistic regression analyses and report odds ratios (OR) and 95% confidence intervals (CI). We calculated different predefined multivariable regression models including demographic variables, comorbidities, initial vital signs, initial blood markers and resuscitation measures. We assessed discrimination by means of area under the receiver operating curve (ROC). Results: Of 240 included patients, 130 (54.2%) survived until hospital discharge and 110 (45.8%) had a favorable neurological outcome. Taurine levels were significantly associated with higher in-hospital mortality (adjusted OR 4.12 (95%CI 1.22 to 13.91), p = 0.02). In addition, a significant association between taurine concentration and a poor neurological outcome was observed (adjusted OR of 3.71 (95%CI 1.13 to 12.25), p = 0.03). Area under the curve (AUC) suggested only low discrimination for both endpoints (0.57 and 0.57, respectively). Conclusion: Admission taurine levels are associated with mortality and neurological outcomes in OHCA patients and may help in the risk assessment of this vulnerable population. Further studies are needed to assess whether therapeutic modulation of taurine may improve clinical outcomes after cardiac arrest.

Background: This study aimed to evaluate whether out-of-hospital cardiac arrest (OHCA) patients with initial shockable rhythm without prehospital return of spontaneous circulation (ROSC) who are directly transported to Heart Centers in appropriate time will have better post-cardiac arrest four months survival and neurological outcomes at discharge. Methods: This retrospective study assessed the data of 1,588 OHCA patients with shockable rhythm and without prehospital ROSC collected from the registry database of Taoyuan City between January 2014 and June 2018. The relationships of transport time to Heart Centers with survival at discharge and with neurological outcomes were investigated for survival analysis. Results: Among the 1,588 OHCA patients with initial shockable rhythm and without prehospital ROSC, 1,222 (77.0%) and 366 (23.0%) were transported to Heart Centers and non-Heart Centers, respectively. However, the transport to Heart Centers was associated with an increased survival at discharge (adjusted odds ratio [aOR] 2.00, 95% confidence interval [CI], 1.42–2.81) and good neurological outcomes (cerebral performance category [CPC] 1 and 2) (aOR 3.14, 95% CI, 1.88–5.23), regardless of the transport time. The overall mortality reduction for Heart Centers was 39% (hazard ratio [HR] = 0.61; 95% CI 0.47–0.78), compared to that for non-Heart Centers. At 120 days of follow-up, the results showed a higher survival rate for patients who were transported to Heart Centers within a short time. The percentages of good CPC showed a better distribution for non-Heart Centers versus those for Heart Centers. Conclusions: Adult OHCA patients with initial shockable rhythm and without prehospital ROSC who were transported to Heart Centers directly had better post-cardiac arrest survival and good neurologic outcomes, regardless of the transport time.

Abstract Background: Patients experiencing cardiac arrest outside medical facilities are at greater risk of death and might have negative neurological outcomes. Cardiopulmonary resuscitation duration affects neurological outcomes of such patients, which suggests that duration of CPR may be vital to patient outcomes.Objectives: The study aims to evaluate the impact of cardiopulmonary resuscitation duration on neurological outcome of patients who have suffered out-of-hospital cardiac arrest.Methods: Data were collected from emergency cases handled by a secondary hospital in industrial Jubail, Saudi Arabia, between 2015 and 2020. There were 257 out-of-hospital cardiac arrest cases, 236 of which resulted in death.Results: Bivariate analysis showed no significant association between cerebral performance category (CPC) outcomes and duration of CPR, gender and cause of death whereas there is statistically significant between CPC and age. (p = 0.001). However, a good CPC outcome was reported with a (mean) limited duration of 8.1 min of CPR; whereas, poor CPC outcomes were associated with prolonged periods of CPR, 13.2 min (mean). Similarly, youthfulness was associated with good CPC outcomes as revealed by the mean age of 5.8 years, whereas a mean rank of 14.9 years was aligned with a poor CPC outcome.Conclusion: Cardiopulmonary Resuscitation Duration out-of-hospital cardiac arrest does not significantly influence the patient neurological outcome in the current study hospital. Other variables may have a more significant effect.

Abstract We aimed to estimate the association between PaCO2 level in the patient after out-of-hospital cardiac arrest (OHCA) resuscitation with patient outcome based on a multicenter prospective cohort registry in Japan between June 2014 and December 2015.Based on the PaCO2 within 24-h after return of spontaneous circulation (ROSC), patients were divided into six groups as follow; severe hypocapnia (<25mmHg), mild hypocapnia (25–35mmHg,), normocapnia (35–45mmHg), mild hypercapnia (45–55mmHg), severe hypercapnia (>55mmHg), exposure to both hypocapnia and hypercapnia. Multivariate logistic regression analysis was conducted to calculate the adjusted odds ratios (aORs) and 95% confidence interval (CI) for the 1-month poor neurological outcome (Cerebral Performance Category ≥3). Among the 13491 OHCA patients, 607 were included. Severe hypocapnia, mild hypocapnia, severe hypercapnia, and exposure to both hypocapnia and hypercapnia were associated with a higher rate of 1-month poor neurological outcome compared with mild hypercapnia (aOR 6.68 [95% CI 2.16–20.67], 2.56 [1.30–5.04], 2.62 [1.06–6.47], 5.63 [2.21–14.34]; respectively). There was no significant difference between the outcome of patients with normocapnia and mild hypercapnia. In conclusion, maintaining normocapnia and mild hypercapnia during the 24-h after ROSC was associated with better neurological outcomes than other PaCO2 abnormalities in this study.

Aim: To develop and validate a model for early prediction of neurological outcomes in non-traumatic out-hospital cardiac arrest (OHCA) patients. Methods: We analyzed the data of adult non-traumatic cardiac arrest patients who experienced return of spontaneous circulation (ROSC) and were admitted to the intensive care unit between January 2013 and December 2017 from the database of a multicenter registry. We allocated 1329 patients who were admitted from 2013 to 2015 to the derivation set and 1025 patients admitted from 2016 to 2017 to the validation set. The primary outcome was the dichotomized Cerebral Performance Category at 30 days. We developed 2 models: model 1 including variables except for laboratory data and model 2 including all variables with laboratory data immediately available after ROSC. Logistic regression with least absolute shrinkage and selection operator regularization was used for model development. The C-statistics for discrimination, the prognostic ability, and calibration of the prediction model were assessed in the validation set. The reclassification of model 2 compared to model 1 was also evaluated by continuous net reclassification index (NRI). Results: The C-statistics [95% confidence intervals] of model 2 and 1 in validation set was 0.940 [0.921-0.959] and 0.935 [0.914-0.957], respectively (Figure 1). The calibration plot showed that both models were well-calibrated to observed neurological outcomes (Figure 2). The model 2 reclassified patients better than the model 1 (NRI: 0.663, p < 0.001). A web-based calculator based on these models was developed that allows clinicians to input the predictor variables needed for the probability of good or poor neurological outcomes (https://pcas-prediction.shinyapps.io/pcas_lasso/). Conclusion: The prediction tool including detailed in-hospital information showed good performance to predict neurological outcomes at 30 days in patients with ROSC after OHCA.

Background and Aim: The benefit of early coronary angiography (CAG) and revascularization in resuscitated out-of-hospital cardiac arrest (OHCA) is unclear. We evaluated the association between early CAG and clinical outcomes in these patients. Methods: Data on all resuscitated adult OHCA cases of cardiac etiology between 2011-2015 were extracted from the prospective Singapore Pan-Asian Resuscitation Outcomes Study and linked with data from the national database of cardiac procedures. The 30-day survival and neurological outcomes (good outcome defined as Cerebral Performance Category [CPC] 1 or 2) were compared between patients undergoing early CAG (within 1-calender day) and patients not undergoing early CAG. Inverse probability weighted estimator was used to adjust for propensity to perform early CAG and PCI. Results: Of 976 consecutive patients who survived to admission (mean age 64±13, 73.7% males), 401 (41.1%) patients underwent CAG and obstructive coronary artery disease (CAD) was present in 352 (87.8%), of whom 284 (70.8%) underwent revascularization. Patients who underwent early CAG (n=337[34.5%]) were significantly different compared to those who underwent delayed or no CAG (n=639[65.5%]) (Table 1). Early CAG and PCI patients had improved survival and better neurological outcomes (adjusted odds ratio [AOR] 3.806 [95% CI 1.675 - 8.648] and AOR 3.075 [95% CI 1.119 - 8.451]), compared to those without. The odds of survival decreased with epinephrine administration (AOR 0.357 [95% CI 0.199 - 0.640]), but increased with an initial shockable rhythm (AOR 6.587 [95% CI 3.659 - 11.861]). The rates of bleeding (2% vs 0%, p=0.300) and stroke (1.6% vs 1.9%, p=0.880) were not increased with early intervention. Conclusion: Early CAG and PCI after OHCA were associated with improved clinical outcomes after OHCA without increasing complications. Further studies are required to identify the characteristics of patients who would benefit most from this invasive strategy.

Purpose: To evaluate serum S100 protein at hospital admission and after 48 h in early neuroprognostication of comatose survivors of out-of-hospital cardiac arrest (OHCA).Methods: The study included 48 consecutive patients after OHCA, who survived for at least 72 h after the event. The patients were divided based on their best cerebral performance category (CPC) achieved over a 30 day follow-up period: favorable neurological outcome (CPC 1–2) vs. unfavorable neurological outcome (CPC 3–4). Predictors of an unfavorable neurological outcome were identified by multivariable regression analysis. Analysis of the receiver operating characteristic curve (ROC) was used to determine the cut-off value for S100, having a 0% false-positive prediction rate.Results: Of the 48 patients, 30 (63%) had a favorable and 18 (38%) had an unfavorable neurological outcome. Eleven patients (23%) died over the 30 day follow-up. Increased S100 levels at 48 h after OHCA, but not the baseline S100 levels, were independently associated with unfavorable neurological outcome, with an area under the ROC curve of 0.85 (confidence interval 0.74–0.96). A 48 h S100 value ≥0.37 μg/L had a specificity of 100% and sensitivity of 39% in predicting an unfavorable 30 day neurological outcome.Conclusion: This study showed that S100 values assessed 48 h after an OHCA could independently predict an unfavorable neurological outcome at 30 days.

Background: Therapeutic hypothermia can improve neurological status in cardiac arrest survivors. Objectives: We investigated the association between the timing of inducing therapeutic hypothermia and neurological outcomes in patients who experienced out-of-hospital cardiac arrest. Methods: We evaluated data from 116 patients who were comatose after return of spontaneous circulation and those who received therapeutic hypothermia between January 2013 and April 2017. The primary endpoint was good neurological outcomes during index hospitalization, defined as a cerebral performance category score of 1 or 2. Therapeutic hypothermia timing was defined as the duration from the return of spontaneous circulation to hypothermia initiation. We analyzed the effect of early hypothermia induction on neurological results. Results: In total, 112 patients were enrolled. The median duration to hypothermia initiation was 284 min (25th–75th percentile, 171–418 min). Eighty-two (69.5%) patients underwent hypothermia within 6 h, and 30 (25.4%) had good neurological outcomes. The rates of good neurological outcomes by hypothermia initiation time quartile (shortest to longest) were 28.3%, 34.5%, 14.8%, and 28.6% (p = 0.401). The good neurologic outcomes did not differ between hypothermia patients within 6 h or after (26.5% vs 26.7%, p = 0.986). Short low-flow time and bystander resuscitation were associated with good neurological outcomes (p = 0.044, confidence interval: 0.027–0.955), but the timing of hypothermia initiation was not (p = 0.602, confidence interval: 0.622–1.317). Conclusion: A shorter low-flow time was associated with good neurological outcomes in out-of-hospital cardiac arrest patients who experienced hypothermia. However, inducing hypothermia sooner, even within 6 h, did not improve the neurological outcomes. Thus, as current guidelines recommend, initiating hypothermia within 6 h of recovery of spontaneous circulation is reasonable.

Background: Skeletal muscle depletion is prevalent in elderly patients and is associated with unfavorable outcomes in patients with chronic diseases. However, the relationship between skeletal muscle mass and neurological outcomes following in-hospital cardiac arrest (IHCA) has not been evaluated. The aim of this study was to investigate whether skeletal muscle status before cardiac arrest is an independent factor affecting neurological outcomes in patients with IHCA.Methods: We reviewed a prospectively enrolled registry of IHCA patients. Consecutive adult patients (&gt;18 years) admitted to a tertiary care hospital from 2013 to 2019 were included in the study. Of these, 421 patients who underwent abdominopelvic computed tomography within 3 months of cardiac arrest were included. Skeletal muscle index (SMI) was measured at the third lumbar vertebra, and skeletal muscle depletion was defined using sex- and body mass index-specific cutoffs of SMI. The primary outcome was a Cerebral Performance Category score of 1 or 2 at 6 months after cardiac arrest, which was considered a good neurological outcome.Results: Of the 421 patients, 248 (58.9%) had skeletal muscle depletion before IHCA. The patients without skeletal muscle depletion showed significantly better neurological outcomes at 6 months after cardiac arrest than those with pre-arrest muscle depletion (20.8 vs. 10.9%, p = 0.004). The absence of skeletal muscle depletion was significantly associated with good neurological outcomes in a multivariable logistic analysis (OR = 3.49, 95% confidence intervals: 1.83–6.65, p &lt; 0.001), along with the absence of diabetes, presence of active cancer, shockable rhythm, and short resuscitation duration.Conclusion: Pre-arrest skeletal muscle depletion was associated with long-term mortality and poor neurological outcomes after IHCA. Skeletal muscle depletion may be used as a tool to identify at-risk patients who may benefit from aggressive treatments.
