In this randomized trial involving patients with out-of-hospital cardiac arrest without ST-segment elevation on postresuscitation electrocardiography, no benefit was found for immediate cardiac ...catherization as compared with delayed or selective catherization.
Abstract
Aims
An increase in out-of-hospital cardiac arrest (OHCA) incidence has been reported in the very early phase of the COVID-19 epidemic, but a clear demonstration of a correlation between the ...increased incidence of OHCA and COVID-19 is missing so far. We aimed to verify whether there is an association between the OHCA difference compared with 2019 and the COVID-19 epidemic curve.
Methods and results
We included all the consecutive OHCAs which occurred in the Provinces of Lodi, Cremona, Pavia, and Mantova in the 2 months following the first documented case of COVID-19 in the Lombardia Region and compared them with those which occurred in the same time frame in 2019. The cumulative incidence of COVID-19 from 21 February to 20 April 2020 in the study territory was 956 COVID-19/100 000 inhabitants and the cumulative incidence of OHCA was 21 cases/100 000 inhabitants, with a 52% increase as compared with 2019 (490 OHCAs in 2020 vs. 321 in 2019). A strong and statistically significant correlation was found between the difference in cumulative incidence of OHCA between 2020 and 2019 per 100 000 inhabitants and the COVID-19 cumulative incidence per 100 000 inhabitants both for the overall territory (ρ 0.87, P < 0.001) and for each province separately (Lodi: ρ 0.98, P < 0.001; Cremona: ρ 0.98, P < 0.001; Pavia: ρ 0.87, P < 0.001; Mantova: ρ 0.81, P < 0.001).
Conclusion
The increase in OHCAs in 2020 is significantly correlated to the COVID-19 pandemic and is coupled with a reduction in short-term outcome. Government and local health authorities should seriously consider our results when planning healthcare strategies to face the epidemic, especially considering the expected recurrent outbreaks.

Graphical Abstract
Extracorporeal cardiopulmonary resuscitation (ECPR) followed by targeted temperature management has been demonstrated to significantly improve the outcomes of out-of-hospital cardiac arrest (OHCA) in ...adult patients. Although recent narrative and systematic reviews on extracorporeal life support in the emergency department are available in the literature, they are focused on the efficacy of ECPR, and no comprehensively summarized review on ECPR for OHCA in adult patients is available. In this review, we aimed to clarify the prevalence, pathophysiology, predictors, management, and details of the complications of ECPR for OHCA, all of which have not been reviewed in previous literature, with the aim of facilitating understanding among acute care physicians. The leading countries in the field of ECPR are those in East Asia followed by those in Europe and the United States. ECPR may reduce the risks of reperfusion injury and deterioration to secondary brain injury. Unlike conventional cardiopulmonary resuscitation, however, no clear prognostic markers have been identified for ECPR for OHCA. Bleeding was identified as the most common complication of ECPR in patients with OHCA. Future studies should combine ECPR with intra-aortic balloon pump, extracorporeal membrane oxygenation flow, target blood pressure, and seizure management in ECPR.
In a randomized trial involving 8014 patients with out-of-hospital cardiac arrest, the use of epinephrine resulted in a significantly higher rate of 30-day survival than placebo but not a higher rate ...of survival with a favorable neurologic outcome.
This study examined whether training in cardiopulmonary resuscitation increases the frequency of bystander CPR and the rate of survival. CPR performed before the arrival of emergency medical services ...was associated with a substantially greater 30-day survival rate.
Out-of-hospital cardiac arrest is a major public health concern, given that there are approximately 420,000 cases in the United States and 275,000 cases in Europe annually.

Bystander cardiopulmonary resuscitation (BCPR) improves survival from out-of-hospital cardiac arrest (OHCA), yet BCPR rates remain low. It is unknown whether BCPR delivery disparities exist based on ...victim gender. We measured BCPR rates by gender in private and public environments, hypothesizing that females would be less likely than males to receive BCPR in public settings, with an associated difference in survival to hospital discharge.
We analyzed data from adult, nontraumatic OHCA events within the Resuscitation Outcomes Consortium registry (2011-2015). Using logistic regression, we modeled the likelihood of receiving BCPR by gender, including patient-level variables, stratified by location. A cohort of 19 331 OHCAs was assessed. Mean age was 64±17 years, and 63% (12 225/19 331) were male. Overall, 37% of OHCA victims received bystander CPR. In public locations, 39% (272/694) of females and 45% (1170/2600) of males received BCPR ( P<0.01), whereas in private settings, 35% (2198/6328) of females and 36% (3364/9449) of males received BCPR ( P=NS). Among public OHCAs, males had significantly increased odds of receiving BCPR compared with females (odds ratio, 1.27; 95% CI, 1.05-1.53; P=0.01); this was not the case in the private setting (odds ratio, 0.93; 95% CI, 0.87-1.01; P=NS). Controlling for site, age, and race, BCPR was significantly associated with survival to hospital discharge (odds ratio, 1.69; 95% CI, 1.54-1.85; P<0.01); in this model, males had 29% increased odds of survival compared with females (odds ratio, 1.29; 95% CI, 1.17-1.42; P<0.01).
Males had an increased likelihood of receiving BCPR compared with females in public. BCPR improved survival to discharge, with greater survival among males compared with females.
To quantitatively summarize the available epidemiological evidence on the survival rate of out-of-hospital cardiac arrest (OHCA) patients who received cardiopulmonary resuscitation (CPR).
We ...systematically searched the PubMed, Embase, and Web of Science databases, and the references of retrieved articles were manually reviewed to identify studies reporting the outcome of OHCA patients who received CPR. The overall incidence and outcome of OHCA were assessed using a random-effects meta-analysis.
A total of 141 eligible studies were included in this meta-analysis. The pooled incidence of return of spontaneous circulation (ROSC) was 29.7% (95% CI 27.6-31.7%), the rate of survival to hospital admission was 22.0% (95% CI 20.7-23.4%), the rate of survival to hospital discharge was 8.8% (95% CI 8.2-9.4%), the pooled 1-month survival rate was 10.7% (95% CI 9.1-13.3%), and the 1-year survival rate was 7.7% (95% CI 5.8-9.5%). Subgroup analysis showed that survival to hospital discharge was more likely among OHCA patients whose cardiac arrest was witnessed by a bystander or emergency medical services (EMS) (10.5%; 95% CI 9.2-11.7%), who received bystander CPR (11.3%, 95% CI 9.3-13.2%), and who were living in Europe and North America (Europe 11.7%; 95% CI 10.5-13.0%; North America: 7.7%; 95% CI 6.9-8.6%). The survival to discharge (8.6% in 1976-1999 vs. 9.9% in 2010-2019), 1-month survival (8.0% in 2000-2009 vs. 13.3% in 2010-2019), and 1-year survival (8.0% in 2000-2009 vs. 13.3% in 2010-2019) rates of OHCA patients who underwent CPR significantly increased throughout the study period. The Egger's test did not indicate evidence of publication bias for the outcomes of OHCA patients who underwent CPR.
The global survival rate of OHCA patients who received CPR has increased in the past 40 years. A higher survival rate post-OHCA is more likely among patients who receive bystander CPR and who live in Western countries.
Background Studies have reported significant reduction in acute myocardial infarction-related hospitalizations during the coronavirus disease 2019 (COVID-19) pandemic. However, whether these trends ...are associated with increased incidence of out-of-hospital cardiac arrest (OHCA) in this population is unknown. Methods and Results Acute myocardial infarction hospitalizations with OHCA during the COVID-19 period (February 1-May 14, 2020) from the Myocardial Ischaemia National Audit Project and British Cardiovascular Intervention Society data sets were analyzed. Temporal trends were assessed using Poisson models with equivalent pre-COVID-19 period (February 1-May 14, 2019) as reference. Acute myocardial infarction hospitalizations during COVID-19 period were reduced by >50% (n=20 310 versus n=9325). OHCA was more prevalent during the COVID-19 period compared with the pre-COVID-19 period (5.6% versus 3.6%), with a 56% increase in the incidence of OHCA (incidence rate ratio, 1.56; 95% CI, 1.39-1.74). Patients experiencing OHCA during COVID-19 period were likely to be older, likely to be women, likely to be of Asian ethnicity, and more likely to present with ST-segment-elevation myocardial infarction. The overall rates of invasive coronary angiography (58.4% versus 71.6%;
<0.001) were significantly lower among the OHCA group during COVID-19 period with increased time to reperfusion (mean, 2.1 versus 1.1 hours;
=0.05) in those with ST-segment-elevation myocardial infarction. The adjusted in-hospital mortality probability increased from 27.7% in February 2020 to 35.8% in May 2020 in the COVID-19 group (
<.001). Conclusions In this national cohort of hospitalized patients with acute myocardial infarction, we observed a significant increase in incidence of OHCA during COVID-19 period paralleled with reduced access to guideline-recommended care and increased in-hospital mortality.
IMPORTANCE: Out-of-hospital cardiac arrest (OHCA) has poor outcome. Whether intra-arrest transport, extracorporeal cardiopulmonary resuscitation (ECPR), and immediate invasive assessment and ...treatment (invasive strategy) is beneficial in this setting remains uncertain. OBJECTIVE: To determine whether an early invasive approach in adults with refractory OHCA improves neurologically favorable survival. DESIGN, SETTING, AND PARTICIPANTS: Single-center, randomized clinical trial in Prague, Czech Republic, of adults with a witnessed OHCA of presumed cardiac origin without return of spontaneous circulation. A total of 256 participants, of a planned sample size of 285, were enrolled between March 2013 and October 2020. Patients were observed until death or day 180 (last patient follow-up ended on March 30, 2021). INTERVENTIONS: In the invasive strategy group (n = 124), mechanical compression was initiated, followed by intra-arrest transport to a cardiac center for ECPR and immediate invasive assessment and treatment. Regular advanced cardiac life support was continued on-site in the standard strategy group (n = 132). MAIN OUTCOMES AND MEASURES: The primary outcome was survival with a good neurologic outcome (defined as Cerebral Performance Category CPC 1-2) at 180 days after randomization. Secondary outcomes included neurologic recovery at 30 days (defined as CPC 1-2 at any time within the first 30 days) and cardiac recovery at 30 days (defined as no need for pharmacological or mechanical cardiac support for at least 24 hours). RESULTS: The trial was stopped at the recommendation of the data and safety monitoring board when prespecified criteria for futility were met. Among 256 patients (median age, 58 years; 44 17% women), 256 (100%) completed the trial. In the main analysis, 39 patients (31.5%) in the invasive strategy group and 29 (22.0%) in the standard strategy group survived to 180 days with good neurologic outcome (odds ratio OR, 1.63 95% CI, 0.93 to 2.85; difference, 9.5% 95% CI, −1.3% to 20.1%; P = .09). At 30 days, neurologic recovery had occurred in 38 patients (30.6%) in the invasive strategy group and in 24 (18.2%) in the standard strategy group (OR, 1.99 95% CI, 1.11 to 3.57; difference, 12.4% 95% CI, 1.9% to 22.7%; P = .02), and cardiac recovery had occurred in 54 (43.5%) and 45 (34.1%) patients, respectively (OR, 1.49 95% CI, 0.91 to 2.47; difference, 9.4% 95% CI, −2.5% to 21%; P = .12). Bleeding occurred more frequently in the invasive strategy vs standard strategy group (31% vs 15%, respectively). CONCLUSIONS AND RELEVANCE: Among patients with refractory out-of-hospital cardiac arrest, the bundle of early intra-arrest transport, ECPR, and invasive assessment and treatment did not significantly improve survival with neurologically favorable outcome at 180 days compared with standard resuscitation. However, the trial was possibly underpowered to detect a clinically relevant difference. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01511666
Abstract Introduction This study reports the epidemiology and outcomes from out-of-hospital cardiac arrest (OHCA) in England during 2014. Methods Prospective observational study from the national ...OHCA registry. The incidence, demographic and outcomes of patients who were treated for an OHCA between 1st January, 2014 and 31st December 2014 in 10 English ambulance service (EMS) regions, serving a population of almost 54 million, are reported in accordance with Utstein recommendations. Results 28,729 OHCA cases of EMS treated cardiac arrests were reported (53 per 100,000 of resident population). The mean age was 68.6 (SD = 19.6) years and 41.3% were female. Most (83%) occurred in a place of residence, 52.7% were witnessed by either the EMS or a bystander. In non-EMS witnessed cases, 55.2% received bystander CPR whilst public access defibrillation was used rarely (2.3%). Cardiac aetiology was the leading cause of cardiac arrest (60.9%). The initial rhythm was asystole in 42.4% of all cases and was shockable (VF or pVT) in 20.6%. Return of spontaneous circulation at hospital transfer was evident in 25.8% (n = 6302) and survival to hospital discharge was 7.9%. Conclusion Cardiac arrest is an important cause of death in England. With less than one in ten patients surviving, there is scope to improve outcomes. Survival rates were highest amongst those who received bystander CPR and public access defibrillation.
