Background: Ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT) are common rhythms seen in out-of-hospital cardiac arrest (OHCA). Although acute myocardial infarction is a frequent cause of VF and pulseless VT, it is unknown whether a strategy of early coronary angiography is associated with improved survival in patients with OHCA. Methods: Using data from the Cardiac Arrest Registry to Enhance Survival (CARES), we identified 1810 adult patients who had an OHCA due to VF, pulseless VT, or an unknown but shockable rhythm and were successfully resuscitated and admitted to a hospital. Using a matched propensity score analysis, we examined the association between a strategy of early coronary angiography within the first day of cardiac arrest and survival to discharge. Results: Early coronary angiography was performed in 874 (48.3%) patients, of whom 523 (59.8%) received coronary stents. Compared to those without early angiography, patients undergoing early coronary angiography were younger (59.9 vs. 62.5 years); more likely to be men (77.9% vs. 64.5%), have a witnessed arrest (86.3% vs. 76.7%), have a diagnosis of ST-elevation myocardial infarction (STEMI) (68.5% vs. 20.3%); and less likely to have known cardiovascular disease (37.3% vs. 54.3%), diabetes (15.4% vs. 26.6%), and renal disease (3.7% vs. 8.3%) (P <0.01 for all comparisons). A total of 565 patients without early angiography were successfully matched to 565 patients with early coronary angiography (c-statistic of 0.77). A strategy of early coronary angiography was associated with higher rates of in-hospital survival (adjusted OR: 1.22, [1.02- 1.45], P=0.025). There were no differences in favorable neurological outcome between the two groups (adjusted OR: 1.10, [0.98-1.23], P=0.12). Conclusion: Among patients with an OHCA due to VF or pulseless VT who were successfully resuscitated and admitted to a hospital, a strategy of early coronary angiography was associated with better survival, which was not compromised by worse neurological outcomes. Given that many patients with an OHCA due to VF or pulseless VT do not currently undergo early coronary angiography, randomized trials are needed to confirm whether a strategy of early coronary angiography can improve outcomes in patients with OHCA.

Abstract Background Little is known about the effectiveness of surface cooling (SC) and endovascular cooling (EC) on the outcome of out-of-hospital cardiac arrest (OHCA) patients receiving target temperature management (TTM) according to their initial rhythm. Methods We retrospectively analysed data from the Japanese Association for Acute Medicine Out‐of‐Hospital Cardiac Arrest registry, a multicentre, prospective nationwide database in Japan. For our analysis, OHCA patients aged ≥ 18 years who were treated with TTM between June 2014 and December 2017 were included. The primary outcome was 30-day survival with favourable neurological outcome defined as a Glasgow–Pittsburgh cerebral performance category score of 1 or 2. Cooling methods were divided into the following groups: SC (ice packs, fans, air blankets, and surface gel pads) and EC (endovascular catheters and any dialysis technique). We investigated the efficacy of the two categories of cooling methods in two different patient groups divided according to their initially documented rhythm at the scene (shockable or non-shockable) using multivariable logistic regression analysis and propensity score analysis with inverse probability weighting (IPW). Results In the final analysis, 1082 patients were included. Of these, 513 (47.4%) had an initial shockable rhythm and 569 (52.6%) had an initial non-shockable rhythm. The proportion of patients with favourable neurological outcomes in SC and EC was 59.9% vs. 58.3% (264/441 vs. 42/72), and 11.8% (58/490) vs. 21.5% (17/79) in the initial shockable patients and the initial non-shockable patients, respectively. In the multivariable logistic regression analysis, differences between the two cooling methods were not observed among the initial shockable patients (adjusted odd ratio [AOR] 1.51, 95% CI 0.76–3.03), while EC was associated with better neurological outcome among the initial non-shockable patients (AOR 2.21, 95% CI 1.19–4.11). This association was constant in propensity score analysis with IPW (OR 1.40, 95% CI 0.83–2.36; OR 1.87, 95% CI 1.01–3.47 among the initial shockable and non-shockable patients, respectively). Conclusion We suggested that the use of EC was associated with better neurological outcomes in OHCA patients with initial non-shockable rhythm, but not in those with initial shockable rhythm. A TTM implementation strategy based on initial rhythm may be important.

Introduction: Out-of-hospital cardiac arrest (OHCA) is associated with high mortality and is most commonly caused by cardiovascular disease. Current guidelines recommend urgent coronary angiography (UCA) if ST-elevation myocardial infarction (STEMI) or high suspicion of acute myocardial infarction exist. Some have advocated for UCA in all OHCA without an obvious non-cardiac cause of arrest. The reasons for large clinical variation in performance of UCA in OHCA are not well understood. Objective: We sought to identify factors associated with performing UCA in OHCA. Methods: A retrospective chart review was conducted on 535 consecutive cardiac arrest patients who achieved return of spontaneous circulation (ROSC) and were admitted at a tertiary academic medical center from January 2008 to August 2014. Exclusion criteria included in-hospital cardiac arrests (201), outside hospital UCA (8), and lack of medical records (1). Univariable analysis followed by multivariable forward selection forcing age and gender were used to determine correlates of performing UCA, defined as within 6 hours of presentation. Results: Out of 325 resuscitated OHCA patients (mean age, 64; women, 35%), 69 were taken to UCA. Factors associated with performing UCA were history of coronary artery disease (CAD) (OR 2.76, 95% CI 1.22-6.28), initial shockable rhythm (OR 3.04, 95% CI 1.31-7.06), following commands post-ROSC (OR 2.77, 95% CI 1.06-7.25), and STEMI (OR 15.17, 95% CI 6.57-35.04). Increasing age (OR 0.97, 95% CI 0.95-0.999) and obvious non-cardiac cause of arrest (OR 0.10, 95% CI 0.03-0.37) were negatively associated. Gender, prior stroke, dementia, bystander cardiopulmonary resuscitation, hypotension, contraindication to anticoagulant, presenting from nursing home or rehabilitation, do not resuscitate order prior to admission, non-English primary language, and presenting during off-hours were not associated with the decision for UCA. Conclusions: In resuscitated out-of-hospital cardiac arrest patients, history of CAD, shockable rhythm, ability to follow commands, and STEMI were associated with performing urgent coronary angiography. Older patients and those with an obvious non-cardiac cause of arrest were less likely to receive coronary angiography.

Introduction: Approximately 1,000 out-of-hospital cardiac arrest (OHCA) occur per day in the United States. Although survival rates remains low, the extent to which OHCA neurological outcomes differ between men and women remains poorly characterized. Methods: Within the national Cardiac Arrest Registry to Enhance Survival (CARES) registry, we identified 195,722 adult individuals with an OHCA between 2013-2017. Using multi-variable logistic regression models, we evaluated for sex differences in rates of survival to hospital discharge and favorable neurological outcome (survival with discharge CPC score of 1 or 2), adjusted for cardiac arrest characteristics, race, location, year of arrest, age, and use of targeted temperature management (TTM) and coronary angiography. Results: Overall, 70,767 (31%) patients were women. Median age was 64 and 62 years for women and men, respectively. An initial shockable rhythm (14.9% vs. 25.7%) and a witnessed arrest (40.9% vs. 45.6%) was more common in men. Bystander CPR was provided to 37% of women and 39% of men. Men were less likely to survive to hospital discharge than women (8.7% vs. 10.9%; adjusted OR 0.75, 95% CI 0.73, 0.78). Similarly, men were less likely to have favorable neurological outcome (6.6% vs. 9.2% for women; adjusted OR 0.78, 95% CI 0.74, 0.82). Further interaction analysis for the pre-hospital elements found small, but statistically significant sex differences in favorable neurological survival for witnessed status (among female OR 2.29, 95% CI 2.10, 2.49; among males OR 2.07, 95% CI 1.92, 2.23, p= 0.04) and for bystander CPR (among females OR 1.20, 95% CI 1.11, 1.29; among males OR 1.34, 95% CI 1.27, 1.42, p= 0.01). Interaction of sex with the hospital level variables of TTM and coronary angiography, for the subset of patients that survived to hospital admission, had no sex differences in favorable neurological outcome. Conclusion: Our analysis shows that for OHCA in the United States, women have better survival outcomes than men. There was a sex differences in the pre-hospital variable of BCPR, but not in the other modifiable variables of TTM and coronary angiography. Further study is needed to better understand sex differences in overall survival and neurological outcomes.

Background: The 2015 cardiopulmonary resuscitation (CPR) guidelines have stressed that high-quality CPR improves survival from cardiac arrest (CA). In particular, the guidelines recommended that it is reasonable for rescuers to perform chest compressions at a rate of 100 to 120/min in adult CA patients. However, it is unknown whether the 2015 guidelines contributed to favorable neurological outcome in adult CA patients. The present study aimed to clarify the effects of the 2015 guidelines in adult CA patients, using the data of the All-Japan Utstein Registry, a prospective, nationwide, population-based registry of out-of-hospital CA (OHCA). Methods: From the data of this registry between 2011 and 2016, we included adult witnessed OHCA patients due to cardiac etiology, who had non-shockable rhythm, PEA and asystole, as an initial rhythm. Study patients were divided into two groups based on the different CPR guidelines; the era of the 2010 guidelines (2010G), and the era of the 2015 guidelines (2015G). The endpoint was the favorable neurological outcome at 30 days after OHCA. Results: The 109,175 patients who met the inclusion criteria comprised 18,764 who received CPR based on 2015G and 90,411 who received CPR based on 2010G. The figure showed favorable neurological outcomes at 30 days in the two groups. In the multivariate analysis, the adjusted odds ratio for 30-day favorable neurological outcome in 2015G patients as compared to 2010G patients was 1.28 (95%CI 1.11-1.46, p<0.001). Conclusion: In the OHCA patients with non-shockable rhythm, the 2015 guidelines were superior to the 2010 guidelines, in terms of neurological benefits.

In the multivariable logistic regression analysis, differences between the two cooling methods were not observed among the initial shockable patients (adjusted odd ratio [AOR] 1.45, 95% CI 0.81–2.60), while EC was associated with better neurological outcome among the initial non-shockable patients (AOR 2.13, 95% CI 1.10–4.13).

A TTM implementation strategy based on initial rhythm may be important.Trial registration: None

Introduction: Current patterns of use of coronary angiography (CAG) among out-of-hospital cardiac arrest (OHCA) patients based on ST segment elevation (STE) on post-resuscitation ECG are not well described. Methods: Using data from the Continuous Chest Compressions trial between 2011 and 2016, we identified OHCA patients who survived to hospitalization. We examined rates of CAG across different trial clusters in the overall cohort and among pre-specified subgroups with presumed cardiac etiology of arrest e.g. initial shockable rhythm and STE on presenting ECG. Results: Of 26,148 OHCA patients across 49 trial clusters, 5608 survived to hospital admission. The mean age of patients was 64 years, with 65% men and 43% with initial shockable rhythm. Among patients with initial shockable rhythm 44% had STE on initial ECG compared with 18% of patients with initial non-shockable rhythm. Use of CAG was significantly higher in patients presenting with STE compared with no STE on initial ECG irrespective of initial rhythm: 70% vs. 31%, p<0.001 for initial shockable rhythm and 28% vs. 5%, p<0.001 for initial non-shockable rhythm. In the overall cohort, there was significant variation in CAG use across trial clusters ranging from 4% - 41% of patients within a trial cluster receiving CAG ( Figure ). This variation persisted among pre-specified subgroups with the proportion of patients within a trial cluster receiving CAG ranged from 11% - 75% for patients with initial shockable rhythm, 0% to 19% with initial non-shockable rhythm, 16% - 82% with STE, 2% - 28% without STE and 0% - 63% in patients with initial shockable rhythm and no STE on presenting ECG ( Figure ). Conclusion: There is a higher use of CAG in STE and shockable cardiac arrest, consistent with presumed cardiac etiology of arrest; however, there is large variation in the use of CAG across sites, even among patients with a presumed cardiac etiology of cardiac arrest suggesting challenges with interpretation of current guidelines.

Background: The optimal timing of coronary angiography (CA) if performed in the management of patients presenting with out-of-hospital cardiac arrest (OHCA) in the absence of ST-Segment elevation myocardial infarction (STEMI) has not been examined by any randomized controlled trial (RCT), though some retrospective studies have suggested benefit of an early approach. Methods: We performed a retrospective analysis of 93 consecutive patients with OHCA and shockable rhythm, without STEMI between July 2007 and April 2014. Patients were categorized by those receiving early (24 hrs.) CA, and the relationship between timing of CA and mortality was assessed, along with key relevant clinical and angiographic variables in each group (Table). Results: Among 93 patients, 45 (48%) received early CA and 48 (52%) late CA. Door-to-angiography median time was 69 (50, 89) minutes in patients undergoing early CA. Patients undergoing early CA were more likely to have a culprit lesion on CA (31% vs. 10%, p=0.01), and a trend toward more frequent PCI (31% vs. 15%, p =0.06) in comparison to late CA. However, they also had a higher baseline lactate level. Inpatient mortality was significantly higher in patients undergoing early CA (27%) compared to those undergoing late CA (4%) (p=0.002). Conclusions: In a series of 93 consecutive patients presenting with OHCA without STEMI, early CA was associated with higher mortality despite a higher frequency of culprit lesions and successful PCI. These results contrast with those from other post-hoc analyses and clearly demonstrate the need for a RCT comparing early vs. late CA in this patient population.

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main funding source(s): Lundbeck Foundation OnBehalf Critical Cardiac Care Research Group Background Approximately half of all patients with acute myocardial infarction complicated by cardiogenic shock (AMICS) present with out-of-hospital cardiac arrest (OHCA). Cardiogenic shock due to OHCA is caused by abrupt cessation of circulation, whereas AMICS without OHCA is due to cardiac failure with low cardiac output. Thus, there may also be differences between the two conditions in terms of blood borne biomarkers. Purpose To explore the potential differences in the admission plasma concentrations of biomarkers reflecting tissue perfusion (lactate), neuroendocrine response (mid-regional proadrenomedullin [MRproADM], Copeptin, pro-atrial natriuretic peptide [proANP]), endothelial damage (Syndecan-1, soluble thrombomodulin [sTM]), inflammation (soluble suppression of tumorigenicity 2 [sST2]) and kidney injury (neutrophil gelatinase-associated lipocalin [NGAL]), in patients with AMICS presenting with or without OHCA. Method Consecutive patients admitted for acute coronary angiography due to suspected ST-elevation myocardial infarction (STEMI) were enrolled during a 1-year period. A total of 2,713 patients were screened. In the present study 86 patients with confirmed STEMI and CS at admission were included. Results Patients with OHCA (had significantly higher median admission concentrations of Lactate (6,9 mmol/L vs. 3.4 mmol/L p &lt;0.001), NGAL (220 ng/ml  vs 150 ng/ml p = 0.046), sTM (10 ng/ml vs. 8.0  ng/ml p = 0.026) and Syndecan-1 (160 ng/ml vs. 120 ng/ml p= 0.015) and significantly lower concentrations of MR-proADM (0.85 nmol/L  vs. 1.6 nmol/L p &lt;0.001) and sST2 (39 ng/ml vs. 62 ng/ml p &lt; 0.001).  After adjusting for age, sex, and time from symptom onset to coronary angiography, lactate (p = 0.008), NGAL (p = 0.03) and sTM (p = 0.011) were still significantly higher in patients presenting with OHCA while sST2 was still significantly lower (p = 0.029). There was very little difference in 30-day mortality between the OHCA and non-OHCA groups (OHCA 37% vs. non-OHCA 38%). Conclusion Patients with STEMI and CS at admission with or without concomitant OHCA had similar 30-day mortality but differed in terms of Lactate, NGAL, sTM and sST2 levels at the time of admission to catheterization laboratory. These findings propose that non-OHCA and OHCA patients with CS could be considered as two individual clinical entities. Abstract Figure. Level of biomarkers OHCA vs. non-OHCA

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: Prolonged conventional cardiopulmonary resuscitation (C-CPR) is associated with a poor prognosis in out-of-hospital cardiac arrest (OHCA) patients. Extracorporeal cardiopulmonary resuscitation (E-CPR) has been utilized as a rescue strategy for patients with cardiac arrest unresponsive to C-CPR. However, the indication and optimal duration to switch from C-CPR to E-CPR are not well established. In addition, the opportunities to develop teamwork skills and expertise to mitigate risks are few. We thus developed the implementation protocol for the E-CPR simulation program, and investigated whether the faster deployment of extracorporeal membrane oxygenation (ECMO) improves the neurological outcome in patients with refractory OHCA. Methods: A total of 42 consecutive patients (age 58±16 years, male ratio 90%, and initial shockable rhythm 64%) received E-CPR (3% of OHCA) during the study period. Among them, 32 (76%) were deployed ECMO during the pre-intervention time period (Pre: from January 2012 to September 2017), whereas 10 (24%) were deployed during the post-intervention time period (Post: October 2017 to May 2019). We compared the door to E-CPR time, collapse to E-CPR time, 30-day mortality, and favorable neurological outcome (Cerebral Performance Categories 1, 2) between the two periods. Results: There was no significant difference in age, the rates of male sex and shockable rhythm, and the time form collapse to emergency room admission between the two periods. The door to E-CPR time and the collapse to E-CPR time were significantly shorter in the post-intervention period compared to the pre-intervention period (Pre: 39 min [IQR; 30-50] vs. Post: 29 min [IQR; 22-31]; P=0.007, Pre: 76 min [IQR; 58-87] vs. Post: 59 min [IQR; 44-68]; P=0.02, respectively). The 30-day mortality was similar between the two periods (Pre: 88% vs. Post: 80%; P=0.6). In contrast, the rate of favorable neurological outcome at the time of discharge was significantly higher in post-intervention period (Pre: 0% vs. Post: 20%; P=0.01) compared to the pre-intervention period. Conclusion: A comprehensive simulation-based training for E-CPR seems to improve the neurological outcome in patients with refractory OHCA patients.
