Major efforts have been made to reduce the burden of sports-related sudden cardiac arrest (SrSCA). The extent to which the incidence, management, and outcomes changed over time has not been investigated.The purpose of this study was to assess temporal trends in SrSCA incidence, management, and survival.Using data from the French National Institute of Health and Medical Research, we evaluated the evolution of incidence, prehospital management, and survival at hospital discharge of SrSCA among subjects aged 18 to 75 years, over 6 successive 2-year periods between 2005 and 2018.Among the 377 SrSCA, 20 occurred in young competitive athletes (5.3%), whereas 94.7% occurred in middle-aged recreational sports participants. Comparing the last 2-year to the first 2-year period, SrSCA incidence remained stable (6.24 vs 7.00 per million inhabitants/y; P = 0.51), with no significant differences in patients' mean age (46.6 ± 13.8 years vs 51.0 ± 16.4 years; P = 0.42), sex (men 94.7% vs 95.2%; P = 0.99), and history of heart disease (12.5% vs 15.9%; P = 0.85). However, frequency of bystander cardiopulmonary resuscitation and public automated external defibrillator use increased significantly (34.9% vs 94.7%; P 0.001 and 1.6% vs 28.8%; P = 0.006, respectively). Survival to hospital discharge improved steadily, reaching 66.7% in the last study period compared with 23.8% in the first (P 0.001).Incidence of SrSCA remained relatively stable over time, suggesting a need for improvement in screening strategies. However, major improvements in on-field resuscitation led to a 3-fold increase in survival, underlining the value of public education in basic life support that should serve as an example for SCA in general.

Emerging data suggest a significant risk for recurrent arrhythmic events after sudden cardiac arrest (SCA) related to coronary vasospasm (CVS) [(1,2)][1]. We aimed to assess the extent to which CVS-related SCA is investigated and managed in the real-world setting. The Paris-SDEC (Paris Sudden Death

BackgroundAlthough epinephrine is essential for successful return of spontaneous circulation (ROSC), the influence of this drug on recovery during the post–cardiac arrest phase is debatable.ObjectivesThis study sought to investigate the relationship between pre-hospital use of epinephrine and functional survival among patients with out-of-hospital cardiac arrest (OHCA) who achieved successful ROSC.MethodsWe included all patients with OHCA who achieved successful ROSC admitted to a cardiac arrest center from January 2000 to August 2012. Use of epinephrine was coded as yes/no and by dose (none, 1 mg, 2 to 5 mg, >5 mg). A favorable discharge outcome was coded using a Cerebral Performance Category 1 or 2. Analyses incorporated multivariable logistic regression, propensity scoring, and matching methods.ResultsOf the 1,556 eligible patients, 1,134 (73%) received epinephrine; 194 (17%) of these patients had a good outcome versus 255 of 422 patients (63%) in the nontreated group (p < 0.001). This adverse association of epinephrine was observed regardless of length of resuscitation or in-hospital interventions performed. Compared with patients who did not receive epinephrine, the adjusted odds ratio of intact survival was 0.48 (95% confidence interval [CI]: 0.27 to 0.84) for 1 mg of epinephrine, 0.30 (95% CI: 0.20 to 0.47) for 2 to 5 mg of epinephrine, and 0.23 (95% CI: 0.14 to 0.37) for >5 mg of epinephrine. Delayed administration of epinephrine was associated with worse outcome.ConclusionsIn this large cohort of patients who achieved ROSC, pre-hospital use of epinephrine was consistently associated with a lower chance of survival, an association that showed a dose effect and persisted despite post-resuscitation interventions. These findings suggest that additional studies to determine if and how epinephrine may provide long-term functional survival benefit are needed.

Acute coronary syndromes (ACS) remain the leading cause of out-of-hospital cardiac arrest (OHCA). Current guidelines plead for early coronary angiography and ad-hoc primary percutaneous coronary intervention (PCI). But after cardiac arrest, shock, hypothermia and modification in antiplatelet
