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.

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.

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 Funding Acknowledgements Japan Society for the Promotion of Science (KAKENHI Grant No. 18K09999) Background In patients with unwitnessed out-of-hospital cardiac arrest (OHCA), the actual no-flow duration (the time with no organ perfusion) is unclear. However, when these patients have a shockable rhythm as an initial recorded rhythm, the no-flow duration may be relatively short as compared with other initial rhythms, and some patients can obtain a good functional outcome after OHCA. Purpose The purpose of the present study was to estimate the no-flow duration and to determine the relationship between no-flow duration and neurologically intact survival in patients with an initial shockable rhythm after OHCA. Methods We reviewed 82,464 patients with OHCA (aged ≥18 years, non-traumatic, witnessed, and without any bystander interventions) who were included in the All-Japan Utstein-style registry from 2013 to 2017. The study end point was 1-month neurologically intact survival (Cerebral Performance Category scale 1 or 2). No-flow duration was defined as the time from emergency call to emergency medical services (EMS) arrival at the patient site. Results The rate of 1-month neurologically intact survival in the patients with an initial shockable rhythm (n = 10,384, 12.6% of overall patients) was 16.5% (1718/10,384). No-flow duration was significantly and inversely associated with 1-month neurologically intact survival (adjusted odds ratios for 1-minute increments: 0.85, 95% confidence interval: 0.84–0.86). The proportion of patients with a shockable rhythm to the overall patients (y, %) had a high correlational relationship with no-flow duration (x, min), depicted by y = 21.0 - 0.95 × x, R² = 0.935. In this analytical model, the number of patients with shockable rhythm reached null at 22 minutes of no-flow duration. The no-flow durations, beyond which the chance for initial shockable rhythm diminished to <10%, <5%, and <1%, were 12, 13, and 17 minutes, respectively. The rate of neurologically intact survival in the patients with shockable rhythm (y, %) and no-flow duration (x, min) were also found to have a strong correlation, depicted by y = 0.16 × x² - 5.12 × x + 45.0, R² = 0.907. The no-flow durations, beyond which the chance for 1-month neurologically intact survival diminished to <10%, <5%, and <1%, were 10, 11, and 15 minutes, respectively. Conclusions In OHCA patients without any bystander interventions before EMS personnel arrival, when a shockable rhythm is recorded by EMS personnel as an initial rhythm, the no-flow duration after cardiac arrest is highly likely to be <17 minutes regardless of the layperson witness status. The limitation of no-flow duration to obtain a 1-month neurologically intact survival after OHCA may be 15 minutes when the patients have an initial shockable rhythm.
