Abstract Background There is scarce evidence about the prevalence and clinical relevance of moderate to severe valvular heart disease (VHD) in survivors of out of hospital cardiac arrest (OHCA). Purpose To determine whether VHD influence prognosis of OHCA survivors. Methods All consecutive patients admitted to the Acute Cardiac Care Unit after OHCA and surviving until hospital discharge were included. All patients received targeted-temperature management according to our local protocol. Univariate and multivariate Cox-proportional hazard models were employed. Results A total of 201 patients were included in the analysis. Mean age was 57.6±14.2 years and 168 (83.6%) were male. Eighteen patients (9.0%) had moderate or severe VHD during index admission (Table 1). Patients with VHD were less frequently of male sex, [11 (61.1%) vs 157 (85.8%), p=0.014], experienced less acute coronary syndrome-related arrhytmias [2 (11.1%) vs 85 (46.5%), p=0.005], and had a lower pH at hospital admission (6.9±1.6 vs 7.2±0.15, p=0.008). During a median follow-up of 40.3 (18.9–69.1) months, patients with VHD showed higher mortality [7 (38.9%) vs 28 (15.3%), p=0.004] and more heart failure-related admissions [7 (38.9%) vs 15 (8.2%), p<0.001]. Only five patients received surgical or percutaneous treatment for VHD during follow-up, with no deaths in this subgroup. Moderate or severe VHD proved to be an independent predictor of global cardiovascular events and specifically heart failure episodes (Figure 1). Table1 Variable With valvular disease Without valvular disease p value Age, mean±DS, years 63.5±13.2 57.0±14.1 0.066 Hypertension, n (%) 12 (66.7) 95 (51.9) 0.231 Diabetes, n (%) 5 (27.8) 24 (13.1) 0.149 Dyslipidaemia, n (%) 7 (38.9) 79 (43.2) 0.726 Smokin habit, n (%) 4 (22.2) 90 (49.2) 0.045 Witnessed cardiac arrest, n (%) 18 (100) 175 (95.6) 1.000 Time from CA to ROSC, mean±DS, minute 19.1±7.5 21.2±13.1 0.506 Shockable rhythm, n (%) 13 (72.2) 163 (89.1) 0.055 LVEF at hospital discharge (%) 42.8±12.1 46.9±14.6 0.254 Figure 1 Conclusion The presence of significant VHD in survivors after OHCA is a predictor of poor outcomes. Specific management of VHD may be specially relevant in this high-risk patients and guideline-oriented therapy, including surgery and percutaneous intervention should be encouraged when indicated.

Abstract Background Data regarding incidence of ventricular (VA) and atrial arrhythmias (AA) in survivors after out-of-hospital cardiac arrest (OHCA) are scarce. Purpose To assess incidence of VA and AA in OHCA patients during long-term follow-up and to identify relevant predictive factors during the index hospital admission. Methods All consecutive patients admitted to the Acute Cardiac Care Unit after OHCA from August 2007 to January 2019 and surviving until hospital discharge were included. Cox proportional hazard models and logistic regression analysis were used to investigate clinical variables related to the incidence of VA and AA. Results The final analysis included 201 patients. Mean age was 57.6±14.2 years and 168 (83.6%) were male. The majority of patients experienced witnessed arrests related to shockable rhythms (176, 87.6%). Thirty-six patients (17.9%) died after a median follow-up of 40.3 months (18.9–69.1), but only 4 presented another cardiac arrest. Eighteen patients (9.0%) suffered new VA and 37 (18.4%) developed atrial fibrillation/atrial flutter. History of coronary heart disease [HR 3.59 (1.37–9.42), p=0.010] and non-acute coronary syndrome-related arrhythmia [HR 5.17 (1.18–22.60), p=0.029] were independent predictors of VA during follow-up. The optimal predictive model for atrial arrhythmias included age at the time of OHCA, LVEF at hospital discharge and non-acute coronary syndrome-related arrhythmias (p<0.001). Table 1 Variable Without VA With VA p value Age, mean ± DS, years 57.4±14.2 60.8±14.7 0.336 Male sex, n (%) 150 (83.3) 15 (83.3) 1.000 Coronary heart disease, n (%) 36 (20.0) 11 (61.1) <0.001 Cardiomyopathy, n (%) 27 (15.0) 8 (44.4) 0.006 Shockable rhythm, n (%) 157 (87.2) 16 (88.9) 1.000 ACS-related arrhythmia (Primary VF), n (%) 83 (46.1) 2 (11.1) 0.004 LVEF at hospital discharge (%) 47.5±13.9 38.3±16.5 0.010 Death during follow-up 32 (17.8) 3 (16.7) 0.603 Cardiac arrest during follow-up 2 (1.1) 2 (11.1) 0.042 CV hospital admission during follow-up 39 (21.7) 14 (77.8) <0.001 Atrial arrhythmias during follow-up 28 (15.6) 9 (50.0) <0.001 Figure 1 Conclusions Despite low incidence of recurrent cardiac arrest, OHCA survivors face a high incidence of VA and AA. Several clinical characteristics during index hospital admission may be useful to identify patients at high risk.

Abstract Background Survival after out-of-hospital cardiac arrest (OHCA) has increased in recent years but is still only 10%. Little is known about the association between post-resuscitation comorbidity and heart failure after discharge from the initial OHCA-admission. Purpose In OHCA-survivors we aimed to describe predictors of left ventricular (LV) dysfunction, defined as LV ejection fraction (LVEF) &lt;40%, at follow-up. Methods A consecutive cohort of OHCA-patients with cardiac cause from 2007 to 2011 without a pre-OHCA congestive heart failure diagnosis (according to the Danish National Patient Registry, which holds data on all Danish citizens) were retrospectively examined. Logistic regression analyses were used to assess factors associated with LV dysfunction (LVEF &lt;40%) at follow-up after a median of 6 months. Follow-up was not performed systematically in the OHCA-survivors and data from follow-up was assessed by reading of patient charts. Results A total of 365 OHCA-survivors with a mean age of 61 years were discharged alive from hospital. LVEF &lt;40% at hospital discharge was seen in 54% (n=184, 7% missing), and at follow-up after a median of 6 months 19% (n=69) of the total OHCA-cohort of survivors still had LV dysfunction. Factors associated with LV dysfunction at follow-up were chronic ischemic heart disease (IHD) prior to OHCA (odds ratio (OR) = 2.9 (95% CI: 1.2 – 7.1)) and ST-elevation myocardial infarction (STEMI) as cause of OHCA (OR = 2.9 (1.4–6.0)), whereas age, gender, high comorbidity burden prior to OHCA or pre-hospital circumstances (including shockable cardiac arrest rhythm) were not. Conclusion More than half of OHCA-survivors with LVEF &lt;40% at hospital discharge improved LV function and LV dysfunction at follow-up after a median of 6 months after discharge was present in 1 in 5 (19%) of the cohort. Chronic IHD and STEMI were the only factors significantly associated with LV dysfunction at follow-up. A systematic follow-up including echocardiography in the outpatient clinic for OHCA-survivors is recommended especially in patients with reduced LV function at discharge and in STEMI-patients in order to assess the appropriateness of heart failure medication and an implantable cardiac defibrillator.

Introduction: Targeted temperature management (TTM) reduces neurologic injury from out-of-hospital cardiac arrest (OHCA). As the risk of neurologic injury increases with prolonged cardiac arrests, the benefit of TTM may depend upon cardiac arrest duration. We hypothesized that there is a time-dependent effect of TTM on neurologic outcomes from OHCA. Methods: Retrospective, observational study of the Toronto RescuNET Epistry-Cardiac Arrest database from 2007 to 2014. We included adult (>18) OHCA of presumed cardiac etiology that remained comatose (GCS<10) after a return of spontaneous circulation. We used multivariable logistic regression to determine the effect of TTM and the duration of cardiac arrest on good neurologic outcome (Modified Rankin Scale (mRS) 0-3) and survival to hospital discharge while controlling for other known predictors. Results: There were 1496 patients who met our inclusion criteria, of whom 981 (66%) received TTM. Of the patients who received TTM, 59% had a good neurologic outcome compared to 39% of patients who did not receive TTM (p< 0.001). After adjusting for the Utstein variables, use of TTM was associated with improved neurologic outcome (OR 1.60, 95% CI 1.10-2.32; p = 0.01) but not with survival to discharge (OR 1.23, 95% CI 0.90-1.67; p = 0.19). The impact of TTM on neurologic outcome was dependent on the duration of cardiac arrest (p<0.05) (Fig 1). Other significant predictors of good neurologic outcome were younger age, public location, initial shockable rhythm, and shorter duration of cardiac arrest (all p values < 0.05). A subgroup analysis found the use of TTM to be associated with neurologic outcome in both shockable (p = 0.01) and non-shockable rhythms (p = 0.04) but was not associated with survival to discharge in either group (p = 0.12 and p = 0.14 respectively). Conclusion: The use of TTM was associated with improved neurologic outcome at hospital discharge. Patients with prolonged durations of cardiac arrest benefited more from TTM.

Abstract Background Out-of-hospital cardiac arrest (OHCA) survivors are a selected group of patients with younger age and less comorbid conditions relative to non-survivors. Long-term risk of stroke, atrial fibrillation or flutter (AF), acute coronary syndrome (ACS) and heart failure (HF) in OHCA survivors not diagnosed with any of these conditions as part of the cardiac arrest is unknown. Purpose To examine 5-year risk of stroke, AF, ACS and HF in 30-day OHCA survivors relative to age- and sex-matched population controls. Methods OHCA 30-day survivors and age- and sex-matched population controls not previously diagnosed with stroke, AF, ACS or HF or during the first 30 days after cardiac arrest were included using Danish Cardiac Arrest Registry data from 2001–2015 as well as the Danish Civil Registration System. Characteristics are compared using totals and percentages for categorical data and median and 25–75% percentiles for continuous data. Five-year outcomes are compared using cumulative incidence plots as well as Shared Frailty Cox regression modeling, unadjusted and adjusted for potential confounders including age, sex, hypertension, diabetes, chronic obstructive pulmonary disease (COPD), peripheral arterial disease (PAD), chronic ischemic heart disease (IHD), transient ischemic attack (TIA), thyroid disease, cholesterol-lowering, antiplatelet and anticoagulant agents. Results Of 4362 30-day survivors, 1063 were stroke-, AF-, ACS- and HF-naïve and 1051 were matched to population controls using age, sex and time of OHCA event as matching variables. The figure depicts the risk of stroke beyond day 30 to 5 years of follow-up was 4.7% versus 1.7% for OHCA survivors vs. controls. Risks of AF, ACS and HF were 7.0% vs. 2.1%, 4.7% versus 1.2% and 12.2% vs. 1.0%, respectively. OHCA 30-day survivors were significantly more likely to have PAD relative to controls, 4.9% vs. 1.1%. Differences in IHD (22.0% vs. 1.7%), hypertension (28.1% vs. 14.6%), diabetes (9.5% vs. 4.1%), lipid-lowering agents (27.6% vs. 9.5%), COPD (11.3% vs. 2.2%) were also significant. When adjusting for these comorbidities as well as for thyroid diseases, chronic kidney disease, cancer, antiplatelet and anticoagulant therapy, differences remained highly significant: HR stroke 3.33 [95% CI 2.21–5.02], HR AF 3.26 [2.28–4.66], HR ACS 3.36 [2.14–5.27] and HR HF 11.50 [8.02–16.48]. Conclusion We demonstrate an increased five-year risk of stroke, atrial fibrillation or flutter, acute coronary syndrome and heart failure in out-of-hospital cardiac arrest survivors without prior existence of any of these conditions. These results indicate that OHCA survivors continue to remain high-risk patients for cardiovascular events and prevention intervention is warranted.

Abstract Background Arginine vasopressin has complex actions in critically ill patients, involving vasoregulatory status, plasma volume, and cortisol levels. Copeptin, a surrogate marker for arginine vasopressin, has shown promising prognostic features in small observational studies and is used clinically for early rule out of acute coronary syndrome. The objective of this study was to explore the association between early measurements of copeptin, circulatory status, and short-term survival after out-of-hospital cardiac arrest. Methods Serial blood samples were collected at 24, 48, and 72 h as part of the target temperature management at 33 °C versus 36 °C after cardiac arrest trial, an international multicenter randomized trial where unconscious survivors after out-of-hospital cardiac arrest were allocated to an intervention of 33 or 36 °C for 24 h. Primary outcome was 30-day survival with secondary endpoints circulatory cause of death and cardiovascular deterioration composite; in addition, we examined the correlation with extended the cardiovascular sequential organ failure assessment (eCvSOFA) score. Results Six hundred ninety patients were included in the analyses, of whom 203 (30.3%) developed cardiovascular deterioration within 24 h, and 273 (39.6%) died within 30 days. Copeptin measured at 24 h was found to be independently associated with 30-day survival, hazard ratio 1.17 [1.06–1.28], p = 0.001; circulatory cause of death, odds ratio 1.03 [1.01–1.04], p = 0.001; and cardiovascular deterioration composite, odds ratio of 1.05 [1.02–1.08], p < 0.001. Copeptin at 24 h was correlated with eCvSOFA score with rho 0.19 [0.12–0.27], p < 0.001. Conclusion Copeptin is an independent marker of severity of the post cardiac arrest syndrome, partially related to circulatory failure. Trial registration Clinical Trials, NCT01020916.

Objective: The B-type natriuretic peptide (BNP) levels could predict future cardiovascular events in congestive heart failure patients. Most studies have correlated basal BNP levels to long-term outcomes. Limited data exist on the prognostic significance of 1-month postdischarge BNP levels after acute heart failure. Methods: Consecutive patients admitted for worsening heart failure were enrolled. BNP was measured at admission, predischarge and at 1-month following discharge. Patients were followed for 1 year for end points of death and rehospitalization. Results: A total of 150 patients (mean age 60.8 + 13.8 years) were included in the heart failure study. 81 (54%) patients had acute heart failure secondary to acute coronary syndrome, while the rest (46%) had acute decompensation of chronic heart failure irrespective of etiology. Mean ejection fraction was 28.6 + 8.9%. 14 patients expired during hospitalization. BNP at admission was an important predictor of in hospital mortality ( P value = .003). Following discharge, 7 events (3 deaths and 4 rehospitalizations) occurred over next 1 month. 1-month outcome was predicted by baseline BNP ( P value = .01) as well as discharge BNP value ( P value = .001). A total of 55 events (26 rehospitalization and 29 deaths) occurred at follow-up of 1 year. Age > 50years, ejection fraction at baseline and all time sequential BNP levels (at admission, discharge, as well as 1 month) were univariate predictors of death and rehospitalization at 1 year. The BNP at 1 month had best discriminative power and remained the lone significant predictor in the multivariate analysis ( P = < .001). Conclusions: 1-month postdischarge BNP level is a useful prognostic factor that predicts mortality and rehospitalization at 1-year follow-up, in patients admitted with heart failure, and helps in identifying patients who need more intensive drug treatment and closer follow-up.

Purpose: High-quality cardiopulmonary resuscitation (CPR) for in-hospital cardiac arrest (IHCA) is the primary component influencing return of circulation (ROSC) and survival to hospital discharge, but few hospitals regularly track these metrics. Other studies have demonstrated significant improvements in survival after IHCA events following implementation of a dedicated code team training program. Therefore, we developed a unique curriculum for a Code Team Training (CTT) course, and evaluated its post-implementation effect on CPR quality and post-IHCA patient outcomes at our institution. Methods: CPR quality data was prospectively collected for quality improvement purposes once our institution had that capability, with 12-months pre-CTT and 21 months post-CTT. Pre-CTT data shaped the elements of the four-hour CTT course that included didactics, small group sessions, and high-fidelity simulation exercises. A total of 456 multi-professional code team members were trained in 22 courses. Data collection included CPR quality and translational outcomes for events where CPR was performed, except the ED. CodeNet® software was used for CPR quality measures, cardiac rhythm, defibrillation metrics, use of continuous waveform capnography, and pauses in compressions. Target metrics for CPR quality were based on 2015 AHA guidelines. Key translational outcomes measures included event location, ROSC, and survival to hospital discharge. Results: CPR quality was obtained from 140 of 230 (61%) in- and out-of-hospital pulseless adult cardiac arrest events over 33 months (50 [36%] before CTT and 90 [64%] following the first course). There was no significant difference between groups in terms of event location within the hospital nor initial event rhythm. A total of 116,908 chest compressions were evaluated. Median compressions in target rate improved from 32% before CTT to 49% after CTT (p<0.05). When accounting for target rate and depth, the median compressions rate improved to 38% post-CTT compared to 31% pre-CTT (p<0.05). While compression depth had a non-statistically significant decline (90.8% pre-CTT and 83.4% post-CTT), mean rate and median rate-in-target improved from 119.99 +/- 15.6 cpm and 32.4% pre-CTT to 113.7 +/- 16.1 cpm and 48.6% post-CTT (p<0.05). The rate of ROSC improved from 60% (30 of 50) to 78% (70 of 90) after implementation of CTT (p=0.003), excluding IHCA in the ED. Index IHCA survival rate for our institution improved from 26% to 33% before and after CTT [p-value NS], which far surpasses the national average (23.8%). Conclusions: After the initiation of a CTT course that targets key code team member personnel, CPR quality significantly improved, which was associated with an increase in ROSC and a trend towards increased survival for in-hospital cardiac arrest patients.

Abstract Background This study is designed to provide detailed knowledge on cognitive impairment after out-of-hospital cardiac arrest (OHCA) and its relation to associated factors, and to validate the neurocognitive screening of the Targeted Hypothermia versus Targeted Normothermia after Out-of-Hospital Cardiac Arrest trial (TTM2-trial), assessing effectiveness of targeted temperature management after OHCA. Methods This longitudinal multi-center clinical study is a sub-study of the TTM2-trial, in which a comprehensive neuropsychological examination is performed in addition to the main TTM2-trial neurocognitive screening. Approximately 7 and 24 months after OHCA, survivors at selected study sites are invited to a standardized assessment, including performance-based tests of cognition and questionnaires of emotional problems, fatigue, executive function and insomnia. At 1:1 ratio, a matched control group from a cohort of acute myocardial infarction (MI) patients is recruited to perform the same assessment. We aim to include 100 patients per group. Potential differences between the OHCA patients and the MI controls at 7 and 24 months will be analyzed with a linear regression, using composite z-scores per cognitive domain (verbal, visual/constructive, working memory, episodic memory, processing speed, executive functions) as primary outcome measures. Results from OHCA survivors on the main TTM2-trial neurocognitive screening battery will be compared with neuropsychological test results at 7 months, using sensitivity and specificity analyses. Discussion In this study we collect detailed information on cognitive impairment after OHCA and compare this to a control group of patients with acute MI. The validation of the TTM2 neurocognitive screening battery could justify its inclusion in routine follow-up. Our results may have a potential to impact on the design of future follow-up strategies and interventions after OHCA. Trial registration ClinicalTrials.gov, NCT03543371. Registered 1 June 2018

Introduction: The relationship between the “chain of survival” metrics of Out of Hospital Cardiac Arrest (OHCA) and survival rates in rural settings has not been fully examined. In previous studies, low survival rate was attributable to the modifiable prehospital metrics and Return Of Spontaneous Circulation (ROSC). We sought to examine the association of the modifiable and non-modifiable OHCA characteristics and patient outcomes with rural settings. Methods: We did a post-hoc analyses of data from the British Columbia cardiac arrest registry, which enrolled all emergency medical system (EMS)-treated OHCAs. All non-EMS-witnessed OHCAs on Vancouver Island from Jan. 2019 to Oct. 2020 were included. The independent variable of interest was rural versus urban settings. Rural areas were defined as all areas outside the urban clusters (population ≥ 1000 and a population density of ≥ 400/km2). Our outcomes were 1. Post resuscitation ROSC, and 2. Survival to hospital discharge. We reported gender-mediated measures and adjusted odds ratios using logistic regression models. Results: We included 1172 OHCA patients, with 23% in rural settings, 33% Female, 30% had ROSC, and 23% survived to hospital discharge. The median EMS response time, from 911-call to first EMS arrival, was prolonged [10.5 mins (IQR 7.5-15)] in rural settings compared to urban settings [6.5 mins (IQR 5-9)] (p value<.001) . Among females, rural settings were associated with higher odds of bystander CPR compared to males [(OR 1.86; 95% CI 1.04-3.35), (OR 1.42; 95% CI 0.95-2.13)], respectively. After adjusting for all covariates, rural settings were associated with lower odds of ROSC among males compared to females [(OR 0.53; 95% CI 0.31-0.90), (OR 0.70; 95% CI 0.34-1.41)], respectively; however, not associated with survival to hospital discharge. Conclusions: There are significant disparities in the modifiable prehospital OHCA characteristics, and post resuscitation ROSC between rural and urban Vancouver Island. An officially integrated rural CPR community-based program, and innovations focused on gender-based implementation may significantly improve OHCA survival rates and subsequent prognostication.
