Abstract Background Patients who suffer a sudden out-of-hospital cardiac arrest (OHCA) may be preceded by warning symptoms and healthcare system contact. Though, is currently difficult early identification of sudden cardiac arrest patients. Purpose We aimed to examine contacts with the healthcare system up to two weeks and one year before OHCA. Methods OHCA patients were identified from the Danish Cardiac Arrest Registry (2001–2014). The pattern of healthcare contacts (with either general practitioner (GP) or hospital) within the year prior to OHCA of OHCA patients was compared with that of 9 sex- and age-matched controls from the background general population. Additionally, we evaluated characteristics of OHCA patients according to the type of healthcare contact (GP/hospital/both/no-contact) and the including characteristics of contacts, within two weeks prior their OHCA event. Results Out of 28,955 OHCA patients (median age of 72 (62–81) years and with 67% male) of presumed cardiac cause, 16,735 (57.8%) contacted the healthcare system (GP and hospital) within two weeks prior to OHCA. From one year before OHCA, the weekly percentages of contacts to GP were relatively constant (26%) until within 2 weeks prior to OHCA where they markedly increased (54%). In comparison, 14% of the general population contacted the GP during the same period (Figure). The weekly percentages of contacts with hospitals gradually increased in OHCA patients from 3.5% to 6.5% within 6 months, peaking at the second week (6.8%), prior to OHCA. In comparison, only 2% of the general population had a hospital contact in that period (Figure). Within 2 weeks of OHCA, patients contacted GP mainly by telephone (71.6%). Hospital diagnoses were heterogenous, where ischemic heart disease (8%) and heart failure (4.5%) were the most frequent. Conclusions There is an increase in healthcare contacts prior to “sudden” OHCA and overall, 54% of OHCA-patients had contacted GP within 2 weeks before the event. This could have implications for developing future strategies for early identification of patients prior to their cardiac arrest. Figure 1.

Abstract Background Each year, there are approximately 5,000 out-of-hospital cardiac arrests (OHCAs) in the state of Victoria, Australia (population 6.4 million, state healthcare budget AUD$2.9 billion / €1.8billion). Mortality from OHCA approaches ninety percent. High mortality rates and survivors not returning to work is likely to have an adverse effect on the Victorian economy but this has not been previously investigated. Purpose To model the economic impact of OHCA mortality and survivors not returning to work. Methods Data on all OHCAs transported by Ambulance Victoria from July 2017- June 2018 in Victoria, Australia was collected, including age, gender, survival to hospital, survival to discharge, and survival to 12 months. Cases were excluded if arrest was precipitated by trauma, exsanguination, overdose, terminal illness, hanging, SIDS, electrocution, sepsis, respiratory causes, drowning, or neurological causes. Pre-arrest employment status of patients was modelled using the Australian Bureau of Statistics Economic Security dataset, which provides contemporary employment rates for gender-matched five-year cohorts for Australians aged 15–79 years. For survivors to 12 months, pre-arrest and post-arrest work status were confirmed. Economic impact was then calculated to a five year horizon utilizing a Markov model with probabilistic sensitivity analysis. Results 4,934 arrests meeting the inclusion criteria were transported by Ambulance Victoria in twelve months, of whom 4,639 were determined to be cardiac arrests without any exclusion criteria as a precipitant. 695 patients survived to hospital (15.0%), and 325 to discharge (7.0%). At 12 months, 303 patients were alive (6.5% of overall cases, 93.2% of those discharged from hospital). Economic modelling of age and gender-matched data indicated that 1516 patients (35%) would have been employed pre-cardiac arrest, but only 216 survivors (4.7%) would be employed at five years post-arrest. Using Markov modelling incorporating estimated earnings and the pre-determined value of a statistical life, the annual economic burden of cardiac arrest approximated AUD$4 billion (€2.5 billion) at a five-year horizon. Conclusion The annual economic impact of cardiac arrest in Victoria, Australia is approximately AUD$4 billion (€2.5 billion) in a five-year horizon. As the annual Victorian state budget for all healthcare is AUD$2.93 billion (€1.8 billion), our data suggests that the economic impact of cardiac arrest is under-appreciated. Therefore, research in this area and providing state-of-the-art care for all cardiac arrest patients should be a healthcare priority.

AimsOut-of-hospital sudden cardiac arrest (SCA) is a rare but devastating event in children and adolescents. The risk is assumed to be higher in children with congenital heart defects (CHDs) than in healthy individuals. The aim of the present study was to investigate the rate of and survival after out-of-hospital cardiac arrest in children 2–18 years old with CHDs.Methods and resultsData concerning all live births in Norway between 1994 and 2009 were retrieved from the Medical Birth Registry of Norway, the patient administrative systems at all hospitals in Norway, the Oslo University Hospital’s Clinical Registry for Congenital Heart Defects and the Norwegian Cause of Death Registry. Survivors were followed through 2012, and supplementary information for the deceased children was retrieved from medical records at Norwegian hospitals. Among the 943 871 live births in Norway from 1994 to 2009, 11 272 (1.2%) children had a CHD. We identified 11 (0.1%) children 2–18 years old with CHDs who experienced out-of-hospital SCA. The estimated rate of out-of-hospital SCA in children 2–18 years old with CHD was 10 per 100 000 person-years. Early cardiopulmonary resuscitation was initiated in all patients. Three children survived.ConclusionsThe incidence of and survival after out-of-hospital SCA in children with CHDs were comparable to the reported rates in the general child population.

Introduction: Myocardial injury is common after out-of-hospital-cardiac arrest (OHCA). However, little is known about the role of early serial hs-TnT in patients with OHCA for identifying myocardial injury, and whether the prevalence and severity of injury differs according to cardiac (CV) vs noncardiac (non-CV) cause of OHCA. Hypothesis: Early hs-TnT will demonstrate high rates of myocardial injury after OHCA regardless of etiology. However, in the first 6 hours after OHCA the extent of hs-TnT elevation and rate of rise will be higher in patients with CV vs non-CV etiology. Methods: Multicenter retrospective study including OHCA patients presenting from 4/1/2018 to 4/1/2019. Hs-TnT was drawn as part of routine clinical care. Results: Baseline hs-TnT was measured in 120 patients after OHCA due to CV (n=51) and non-CV (n=69) etiologies, with subsequent serial hs-TnT values at 1hr, 3hrs, and 6hrs. Hs-TnT was greater than the 99 th percentile in 97% (115/120) of patients and myocardial injury (hs-TnT> 52ng/L) was detected in 88% (105/120) of patients (no difference between CV vs non-CV etiology). Median hs-TnT values were compared between CV and non-CV etiologies of OHCA identifying no difference in hs-TnT at baseline (Figure: 54 [IQR 18-134] vs. 41 [IQR 19-100]; p=0.357) but significantly higher hs-TnT in patients with CV etiology at 1hr (159 [IQR 80-392] vs 93 [IQR 42-247]; p=0.049), 3hrs (400 [IQR 168-1005] vs 151 [IQR 75-401] p=0.009), and 6hrs (746 [IQR 248-1965] vs 251 [IQR 75-580]; p=0.001). Additionally, hs-TnT rise from baseline was present in both CV and non-CV etiologies but was significantly higher in patients with CV etiology (p = 0.005). Conclusions: As identified by hs-TnT, myocardial injury was prevalent in patients with both CV and non-CV cause of OHCA. Baseline hs-TnT was no different in patients with CV vs non-CV cause, however, over the first 6 hours both absolute value and rate of hs-TnT rise were significantly higher for patients with CV vs non-CV etiology of OHCA.

Background: Sudden cardiac arrest (SCA) and especially the out of hospital cardiac arrest (OHCA) is always an urgent situation, which requires well trained medical personnel. The emergency medical system (EMS) in Vienna took part in the Circulation Improving Care (CIRC) trial form 2008 to 2010. In this time they had an additional training. Therefore we revaluated the outcome of OHCA nowadays. Method: Interim report of a prospective observational study of all humans over eighteen, who suffer an OHCA resuscitated by the EMS in Vienna from August 2013 - April 2014. For those patients, who survived 30 days, a cerebral performance category score (CPC) was evaluated. Results: During nine months 701 patients could be investigated and 625 achieved the protocol for this trial. The median age of the patients was 68 years (IQR 59-79) and 399 (64%) were male. Witnessed by bystanders was the cardiac arrest in 359 (57%) patients. In the latter patients restoration of spontaneous circulation (n=223, 36%)(ROSC) and 30 day survival (n=166, 27%) was significantly more often achieved than in patients with non-witnessed cardiac arrest. Bystanders provided chest compressions in 284 (45%) cases and in this subgroup a shockable initial rhythm was more often (p<0.0001). Still in 189 (53%) of the patients where the cardiac arrest was witnessed, bystander resuscitation wasn′t attempted. An initial shockable rhythm was found in 146 (24%) patients with significant better outcome in all primary outcome measures. Of the 62 (10%) 30-days-survivors, 33 (6%) had good neurological outcome with a CPC 1-2.In 12 (2%) cases the CPC was missing. Conclusion: The results are comparable to findings of our previous studies. A significant better result in all primary outcome measures could be found for witnessed OHCA with an initial shockable rhythm. Furthermore those patients with bystander CPR had significant more often a shockable initial rhythm. Therefore more efforts have to be invested into encouraging the community to start with a bystander CPR if an OHCA is witnessed.

Recent observational studies have found associations between poorer outcomes and treatment that included mechanical CPR devices, contradicting findings from randomized trials. Resuscitation time bias is a systematic error occurring in observational studies of interventions applied to pulseless patients later in resuscitation attempts. Previous observational studies lack data on duration of resuscitation, a factor strongly related to outcome. We retrospectively analyzed cardiac arrest data to learn how resuscitation time and device use relate to clinical outcomes, and determine whether resuscitation time bias was present. Methods and Results: We analyzed data from all 49 patients with ventricular fibrillation, out-of-hospital cardiac arrest treated by our emergency medical service in one year. We compared 19 patients who received only standard manual CPR (the sCPR group) to 30 patients who received manual followed by mechanical CPR (the mCPR group). Response to CPR differed between groups even before device application. All sCPR patients achieved return of spontaneous circulation (ROSC), and did so after a median (IQR) of 3.3 (2.2-5.1) minutes of manual CPR. Patients in the mCPR group failed to get ROSC through 6.9 (5.3-11.0) min of manual CPR; mCPR patients that did get ROSC did so after 11.2 (5.7-23.8) additional minutes of CPR, delivered by a mechanical device. mCPR patients also received significantly more defibrillations and ALS drugs. ROSC and survival to hospital discharge were higher in the sCPR than the mCPR group (100% vs. 70%, P = 0.008; 74% vs. 43%, P = 0.045). Conclusion: Only patients remaining pulseless after early resuscitation efforts received mechanical CPR. Consequently, mechanical CPR devices assisted by facilitating prolonged treatment of patients who already had lower chances of survival before device application. Resuscitation time bias was present, and must be considered when interpreting registry reports comparing sCPR and mCPR.

Abstract Aims Various drugs increase the risk of out-of-hospital cardiac arrest (OHCA) in the general population by impacting cardiac ion channels, thereby causing ventricular tachycardia/fibrillation (VT/VF). Dihydropyridines block L-type calcium channels, but their association with OHCA risk is unknown. We aimed to study whether nifedipine and/or amlodipine, often-used dihydropyridines, are associated with increased OHCA risk, and how these drugs impact on cardiac electrophysiology. Methods and results We conducted a case–control study with VT/VF-documented OHCA cases with presumed cardiac cause from ongoing population-based OHCA registries in the Netherlands and Denmark, and age/sex/index date-matched non-OHCA controls (Netherlands: PHARMO Database Network, Denmark: Danish Civil Registration System). We included 2503 OHCA cases, 10 543 non-OHCA controls in Netherlands, and 8101 OHCA cases, 40 505 non-OHCA controls in Denmark. To examine drug effects on cardiac electrophysiology, we performed single-cell patch-clamp studies in human-induced pluripotent stem cell-derived cardiomyocytes. Use of high-dose nifedipine (≥60 mg/day), but not low-dose nifedipine (&lt;60 mg/day) or amlodipine (any-dose), was associated with higher OHCA risk than non-use of dihydropyridines [Netherlands: adjusted odds ratios (ORadj) 1.45 (95% confidence interval 1.02–2.07), Denmark: 1.96 (1.18–3.25)] or use of amlodipine [Netherlands: 2.31 (1.54–3.47), Denmark: 2.20 (1.32–3.67)]. Out-of-hospital cardiac arrest risk of (high-dose) nifedipine use was not further increased in patients using nitrates, or with a history of ischaemic heart disease. Nifedipine and amlodipine blocked L-type calcium channels at similar concentrations, but, at clinically used concentrations, nifedipine caused more L-type calcium current block, resulting in more action potential shortening. Conclusion High-dose nifedipine, but not low-dose nifedipine or any-dose amlodipine, is associated with increased OHCA risk in the general population. Careful titration of nifedipine dose should be considered.
