Abstract Background Sudden cardiac arrest (SCA) during sports can be the first symptom of yet undetected cardiovascular conditions. Immediate chest compressions and early defibrillation offer SCA victims the best chance of survival, which requires prompt bystander cardiopulmonary resuscitation (CPR). Aims To determine the effect of rapid bystander CPR to SCA during sports by searching for and analyzing videos of these SCA/SCD events from the internet. Methods We searched images.google.com, video.google.com, and YouTube.com, and included any camera-witnessed non-traumatic SCA during sports. The rapidity of starting bystander chest compressions and defibrillation was classified as < 3, 3–5, or > 5 min. Results We identified and included 29 victims of average age 27.6 ± 8.5 years. Twenty-eight were males, 23 performed at an elite level, and 18 participated in soccer. Bystander CPR < 3 min (7/29) or 3–5 min (1/29) and defibrillation < 3 min was associated with 100% survival. Not performing chest compressions and defibrillation was associated with death (14/29), and > 5 min delay of intervention with worse outcome (death 4/29, severe neurologic dysfunction 1/29). Conclusions Analysis of internet videos showed that immediate bystander CPR to non-traumatic SCA during sports was associated with improved survival. This suggests that immediate chest compressions and early defibrillation are crucially important in SCA during sport, as they are in other settings. Optimal use of both will most likely result in survival. Most videos showing recent events did not show an improvement in the proportion of athletes who received early resuscitation, suggesting that the problem of cardiac arrest during sports activity is poorly recognized.

Bystander Cardiopulmonary Resuscitation

Background: Sports-related sudden cardiac arrest (sport SCA) has always attracted attention and the United States and European Union have developed divergent strategies for prevention over the last decade; notably regarding screening of younger athletes but also for SCA prevention in middle-aged and senior individuals. In this context, the extent to which outcomes of sports SCA differ between Europe and the USA have not been characterized. Methods: SCA cases aged 15-75 years were identified in two large prospective, population-based SCA programs, one in the Paris region (Paris-SDEC) and the other in a Northwestern US metro region (Oregon-SUDS) between 2002 and 2012. Cases of SCA, occurring during sports activity were compared between the two regions. Results: Of the 7,357 cases studied, 290 (4%) occurred during sports, with very similar proportions in both regions: 86 out of 1,894 (4.5%) in Oregon and 204 out of 5,463 (3.8%) in Paris. Subjects’ characteristics of cases in both programs were very similar (Paris vs. Oregon, respectively, for all results following), regarding age (50.7±14 vs. 50.4±13 years, P=0.55), male proportion (94%vs. 92%, P=0.53), past medical history of ≥2 cardiovascular risk factors (16% vs. 23%, P=0.16) and/or heart disease (10% vs. 8%, P=0.55). There was a high proportion of witnessed events in both populations (89% vs. 90%, P=0.94). However, we observed significant differences with more bystander cardiopulmonary resuscitation in Paris (63% vs. 48%, P=0.02), faster response time in Oregon (8.3±6 vs. 6.9±4 min, P=0.05), and more initially shockable rhythms in Oregon (52% vs. 70%, P=0.006). Overall, resuscitation outcomes were very similar for return of spontaneous circulation (26% vs. 33%, P=0.21) and survival to hospital discharge (27% vs. 26%, P=0.80). Conclusions: On either side of the Atlantic, burden and characteristics of sports-related SCA are very similar. Survival rates are approximately one in four cases. Optimizing bystander cardiopulmonary resuscitation rates and emergency response times could further improve outcomes. Deployment of uniform, effective strategies for screening and prevention are likely to make the greatest impact on sports SCA.

Background Bystander cardiopulmonary resuscitation (CPR) is a critical intervention to improve survival following out‐of‐hospital cardiac arrest. We evaluated the quality of bystander CPR and whether performance varied according to the number of bystanders or provision of telecommunicator CPR (TCPR). Methods and Results We investigated non‐traumatic out‐of‐hospital cardiac arrest occurring in a large metropolitan emergency medical system during a 6‐month period. Information about bystander care was ascertained through review of the 9‐1‐1 recordings in addition to emergency medical system and hospital records to determine bystander CPR status (none versus TCPR versus unassisted), the number of bystanders on‐scene, and CPR performance metrics of compression fraction and compression rate. Of the 428 eligible out‐of‐hospital cardiac arrest, 76.4% received bystander CPR including 43.7% unassisted CPR and 56.3% TCPR; 35.2% had one bystander, 33.3% had 2 bystanders, and 31.5% had ≥3 bystanders. Overall compression fraction was 59% with a compression rate of 88 per minute. CPR differed according to TCPR status (fraction=52%, rate=87 per minute for TCPR versus fraction=69%, rate=102 for unassisted CPR, P <0.05 for each comparison) and the number of bystanders (fraction=55%, rate=87 per minute for 1 bystander, fraction=59%, rate=89 for 2 bystanders, fraction=65%, rate=97 for ≥3 bystanders, test for trend P <0.05 for each metric). Additional bystander actions were uncommon to include rotation of compressors (3.1%) or application of an automated external defibrillator (8.0%). Conclusions Bystander CPR quality as gauged by compression fraction and rate approached guideline goals though performance depended upon the type of CPR and number of bystanders.

Background The mechanism by which bystander cardiopulmonary resuscitation (CPR) improves survival following out‐of‐hospital cardiac arrest is unclear. We hypothesized that ventricular fibrillation (VF) waveform measures, as surrogates of myocardial physiology, mediate the relationship between bystander CPR and survival. Methods and Results We performed a retrospective cohort study of adult, bystander‐witnessed patients with out‐of‐hospital cardiac arrest with an initial rhythm of VF who were treated by a metropolitan emergency medical services system from 2005 to 2018. Patient, resuscitation, and outcome variables were extracted from emergency medical services and hospital records. A total of 3 VF waveform measures (amplitude spectrum area, peak frequency, and median peak amplitude) were computed from a 3‐second ECG segment before the initial shock. Multivariable logistic regression estimated the association between bystander CPR and survival to hospital discharge adjusted for Utstein elements. Causal mediation analysis quantified the proportion of survival benefit that was mediated by each VF waveform measure. Of 1069 patients, survival to hospital discharge was significantly higher among the 814 patients who received bystander CPR than those who did not (0.52 versus 0.43, respectively; P <0.01). The multivariable‐adjusted odds ratio for bystander CPR and survival was 1.6 (95% CI, 1.2, 2.1), and each VF waveform measure attenuated this association. Depending on the specific waveform measure, the proportion of mediation varied: 53% for amplitude spectrum area, 31% for peak frequency, and 29% for median peak amplitude. Conclusions Bystander CPR correlated with more robust initial VF waveform measures, which in turn mediated up to one‐half of the survival benefit associated with bystander CPR. These results provide insight into the biological mechanism of bystander CPR in VF out‐of‐hospital cardiac arrest.

Sudden cardiac arrest is a leading cause of death worldwide. Despite significant advances in resuscitation science since the initial use of external chest compressions in humans nearly 60 years ago, there continues to be wide variability in rates of successful resuscitation across communities. The American Heart Association (AHA) and European Resuscitation Council emphasise the importance of high-quality chest compressions as the foundation of resuscitation care. We review the physiological basis for the association between chest compression quality and clinical outcomes and the scientific basis for the AHA’s key metrics for high-quality cardiopulmonary resuscitation. Finally, we highlight that implementation of strategies that promote effective chest compressions can improve outcomes in all patients with cardiac arrest.

Background: Dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) can increase bystander CPR rates and improve outcomes in out-of-hospital cardiac arrest (OHCA). Protocols used by dispatchers are designed to provide a quick assessment for prompt initiation of CPR. However, there are instances where non-cardiac arrest cases are falsely recognised by dispatchers to be in cardiac arrest. These patients may go on to receive chest compressions and potentially suffer from complications of unnecessary CPR, though the clinical implications of starting DA-CPR on these non-cardiac arrest cases have not been studied. Hence, the objectives of this study are to find the prevalence and clinical outcomes of DA-CPR in patients not in cardiac arrest in the Singapore population. Methods: This was a multi-center, observational study of all dispatcher-recognized cardiac arrests cases between January to December 2017 involving three tertiary hospitals in Singapore. Data was collected through audio review of dispatch calls from the national emergency ambulance service and information about patients’ clinical outcomes were prospectively collected from health records. Results: During the study period, dispatchers recognised 821 patients as having cardiac arrest. Of these, 40.0% (328/ 821) were not in cardiac arrest. 52.7% (173/ 328) of the non-cardiac arrest patients had chest compressions initiated under dispatcher assistance. No complications from chest compressions were reported. The top diagnoses of non-cardiac arrest patients found were cerebrovascular accidents (CVA), syncope and infection. A multiple logistic regression model with estimates adjusted for the presence or absence of chest compressions revealed that only final diagnoses of CVA (OR 20.68), infection (OR 17.34) and myocardial infarction (OR 32.19) were associated with in-hospital mortality. Conclusion: In this study, chest compressions initiated due to false recognition of cardiac arrest by dispatchers did not result in any reported complications and was not associated with in-hospital mortality. This provides reassurance for the continued implementation of DA-CPR.

​ObjectiveCardiopulmonary resuscitation (CPR) performed before the arrival of emergency medical services (EMS) is associated with increased survival after out-of-hospital cardiac arrest (OHCA). The aim of this study was to determine whether patients who receive bystander CPR have a different comorbidity compared with patients who do not, and to determine the association between bystander CPR and 30-day survival when adjusting for such a possible difference.​MethodsPatients with witnessed OHCA in the Swedish Registry for Cardiopulmonary Resuscitation between 2011 and 2015 were included, and merged with the National Patient Registry. The Charlson Comorbidity Index (CCI) was used to measure comorbidity. Multiple logistic regression was used to examine the effect of CCI on the association between bystander CPR and outcome.​ResultsIn total, 11 955 patients with OHCA were included, 71% of whom received bystander CPR. Patients who received bystander CPR had somewhat lower comorbidity (CCI) than those who did not (mean±SD: 2.2±2.3 vs 2.5±2.4; p<0.0001). However, this difference in comorbidity had no influence on the association between bystander CPR and 30-day survival in a multivariable model including other possible confounders (OR 2.34 (95% CI 2.01 to 2.74) without adjustment for CCI and OR 2.32 (95% CI 1.98 to 2.71) with adjustment for CCI).​ConclusionPatients who undergo CPR before the arrival of EMS have a somewhat lower degree of comorbidity than those who do not. Taking this difference into account, bystander CPR is still associated with a marked increase in 30-day survival after OHCA.

Abstract Background Out-of-hospital cardiac arrest (OHCA), a global health problem with a survival rate ranging from 2 to 22% across different countries, has been a leading cause of premature death for decades. The aim of this study was to evaluate the trends of survival after OHCA over time and its relationship with bystander cardiopulmonary resuscitation (CPR), initial shockable rhythm, return of spontaneous circulation (ROSC), and survived event. Methods In this prospective observational study, data of OHCA patients were collected following the “Utstein style” by the Beijing, China, Emergency Medical Service (EMS) from January 2011 (data from February to June in 2011 was not collected) to October 2016. Patients who had a cardiac arrest and for whom an ambulance was dispatched were included in this study. All cases were followed up to determine hospital discharge or death. The trend of OHCA survival was analyzed using the Chi-square test. The relationship among bystander CPR, initial shockable rhythm, ROSC, survived event, and OHCA survival rate was analyzed using multivariate path analyses with maximum standard likelihood estimation. Results A total of 25,421 cases were transferred by the Beijing EMS; among them, 5042 (19.8%) were OHCA (median age: 78 years, interquartile range: 63–85, 60.1% male), and 484 (9.6%) received bystander CPR. The survival rate was 0.6%, which did not improve from 2012 to 2015 (P = 0.569). Overall, bystander CPR was indirectly associated with an 8.0% (β = 0.080, 95% confidence interval [CI] = 0.064–0.095, P = 0.002) increase in survival rate. The indirect effect of bystander CPR on survival rate through survived event was 6.6% (β = 0.066, 95% CI = 0.051–0.081, P = 0.002), which accounted for 82.5% (0.066 of 0.080) of the total indirect effect. With every 1 increase in survived event, the possibility of survival rate will directly increase by 53.5% (β = 0.535, 95% CI = 0.512–0.554, P = 0.003). Conclusions The survival rate after OHCA was low in Beijing which has not improved between 2012 and 2015. The effect of bystander CPR on survival rate was mainly mediated by survived event.
