- Abstract
Background: Out-of-hospital cardiac arrest (OHCA) is associated with ∼90% mortality rate. In the pediatric population, this would equate to a large number of years of life lost, posing a heavy medical and economic burden to society., Objective: The purpose of this study was to outline the characteristics and causes of pediatric OHCA (pOHCA) and associations with survival until discharge in patients enrolled in the End Unexplained Cardiac Death Registry., Methods: A prospective statewide multisource registry identified all pOHCAs cases in patients aged 1-18 years in Victoria, Australia (population 6.5 million), from April 2019 to April 2021. Cases were adjudicated using ambulance, hospital, and forensic records; clinic assessments; and interviews of survivors and family members., Results: The analysis included 106 cases after adjudication (62, 58.5% male), 45 (42.5%) of which were due to cardiac causes of OHCA, with unascertained (n = 33 [31.1%]) being the most common cardiac cause reported. Respiratory events (n = 28 [26.4%]) were the most common noncardiac cause of pOHCA. Noncardiac causes were more likely to present with asystole or pulseless electrical activity (P = .007). The overall survival to hospital discharge rate was 11.3% and associated with increasing age, witnessed cardiac arrest, and initial ventricular arrhythmias (P < .05)., Conclusion: The incidence of pOHCA in the study population was 3.69 per 100,000 child-years. In contrast to young adults with OHCA, the most common etiology was noncardiac in pediatric patients. Prognostic factors associated with survival to discharge included increasing age, witnessed arrest, and initial ventricular arrhythmias. Rates of cardiopulmonary resuscitation and defibrillation were suboptimal., (Crown Copyright © 2023. Published by Elsevier Inc. All rights reserved.)

- Abstract
Aims: The causes, circumstances, and preventability of young sudden cardiac arrest remain uncertain., Methods and Results: A prospective state-wide multi-source registry identified all out-of-hospital cardiac arrests (OHCAs) in 1-50 year olds in Victoria, Australia, from 2019 to 2021. Cases were adjudicated using hospital and forensic records, clinic assessments and interviews of survivors and family members. For confirmed cardiac causes of OHCA, circumstances and cardiac history were collected. National time-use data was used to contextualize circumstances. 1319 OHCAs were included. 725 (55.0%) cases had a cardiac aetiology of OHCA, with coronary disease (n = 314, 23.8%) the most common pathology. Drug toxicity (n = 226, 17.1%) was the most common non-cardiac cause of OHCA and the second-most common cause overall. OHCAs were most likely to occur in sleep (n = 233, 41.2%). However, when compared to the typical Australian day, OHCAs occurred disproportionately more commonly during exercise (9% of patients vs. 1.3% of typical day, P = 0.018) and less commonly while sedentary (39.6 vs. 54.6%, P = 0.047). 38.2% of patients had known standard modifiable cardiovascular risk factors. 77% of patients with a cardiac cause of OHCA had not reported cardiac symptoms nor been evaluated by a cardiologist prior to their OHCA., Conclusion: Approximately half of OHCAs in the young have a cardiac cause, with coronary disease and drug toxicity dominant aetiologies. OHCAs disproportionately occur during exercise. Of patients with cardiac cause of OHCA, almost two-thirds have no standard modifiable cardiovascular risk factors, and more than three-quarters had no prior warning symptoms or interaction with a cardiologist., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2022.

- Abstract
Objective: To determine whether young rural Australians have higher rates or different underlying causes of out-of-hospital cardiac arrest (OHCA)., Design: A case-control design identified patients experiencing an OHCA, then compared annual OHCA rates and underlying causes in rural versus metropolitan Victoria. OHCA causes were defined as either cardiac or non-cardiac, with specific aetiologies including coronary disease, cardiomyopathy, unascertained cause of arrest, drug toxicity, respiratory event, neurological event and other cardiac and non-cardiac. For OHCAs with confirmed cardiac aetiology, cardiovascular risk profiles were compared., Setting: A state-wide prospective OHCA registry (combining ambulance, hospital and forensic data) in the state of Victoria, Australia (population 6.5 million)., Participants: Victorians aged 1-50 years old experienced an OHCA between April 2019 and April 2020., Main Outcome Measures: Rates and underlying causes of OHCA in young rural and metropolitan Victorians., Results: Rates of young OHCA were higher in rural areas (OHCA 22.5 per 100 000 rural residents vs. 13.4 per 100 000 metropolitan residents, standardised incidence ratio 168 (95% CI 101-235); confirmed cardiac cause of arrest 12.1 per 100 000 rural residents versus 7.5 per 100 000 metropolitan residents, standardised incidence ratio 161 (95% CI 71-251). The underlying causation of the OHCA and cardiovascular risk factor burden did not differ between rural and metropolitan areas., Conclusion: Higher rates of OHCA occur in young rural patients, with standardised incidence ratio of 168 compared to young metropolitan residents. Rural status did not influence causes of cardiac arrest or known cardiovascular risk factor burden in young patients experiencing OHCA., (© 2022 National Rural Health Alliance Ltd.)

- Abstract
Background: Forensic investigations are recommended following sudden cardiac death (SCD) to determine cause of death and identify living relatives at potential risk. Not all young SCD patients are referred to coronial services., Objective: The purpose of this study was to identify referral rates, predictors, and outcomes of young SCD patients who die in-hospital following out-of-hospital cardiac arrest (OHCA)., Methods: A prospective 2-year analysis of in-hospital deaths following OHCA in Victoria, Australia, was conducted using a statewide registry combining data from ambulance, hospital, and forensic resources., Results: OHCA caused 26.3% of all deaths (n = 1301) in Victorians aged 1-50 years. Rates of prehospital and in-hospital referral to coronial services were 95.0% and 59.5%, respectively. Factors independently predicting in-hospital coronial referral were age <40 years, death in the emergency department, and rural status (odds ratios 4.07, 8.91, and 3.43, respectively). Establishing a diagnosis of coronary disease in-hospital substantially reduced odds of coronial referral (odds ratio 0.07). Of 107 SCD patients referred to the coroner from hospitals, 25 (23.3%) had illicit substances identified on toxicologic analysis. Eighty-one patients (75.7%) underwent autopsy, with cause of death determined in 65 cases (80.2%). Sixteen deaths (19.8%) remained unascertained after autopsy and ancillary investigations., Conclusion: More than one-fourth of young Victorian deaths result from OHCA. Approximately half of patients dying in-hospital following OHCA are referred to the coroner. Patients referred are younger, more likely to die in the emergency department, and reside rurally. Forensic assessment identifies high rates of illicit drug use in young SCD patients and provides a definitive cause of death for most patients., (Copyright © 2022 Heart Rhythm Society.
