Delayed neurologic improvement and long-term survival of patients with poor neurologic status after out-of-hospital cardiac arrest: a retrospective cohort study in Japan. Resuscitation 2023:109790. [PMID: 37024037 DOI: 10.1016/j.resuscitation.2023.109790] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Revised: 03/26/2023] [Accepted: 03/28/2023] [Indexed: 04/08/2023]
Abstract
AIM To assess survival duration and frequency of delayed neurologic improvement in patients with poor neurologic status at discharge from emergency hospitals after out-of-hospital cardiac arrest (OHCA). METHODS This retrospective cohort study included OHCA patients admitted to two tertiary emergency hospitals in Japan between January 2014 and December 2020. Pre-hospital, tertiary emergency hospital, and post-acute care hospital data, were retrospectively collected by reviewing medical records. Neurologic improvements were defined as an improvement of Cerebral Performance Category (CPC) scores from 3 or 4 at hospital discharge to 1 or 2. The primary outcome was neurologic improvement after discharge, while the secondary outcome was survival time after cardiac arrest. RESULTS Of all patients (n=1,012) admitted to tertiary emergency hospitals after OHCA during the observation period, 239 with CPC 3 or 4 at discharge were included, and all were Japanese. Median age was 75 years, 64% were male, and 31% had initially shockable rhythms. Neurologic improvements were observed in nine patients (3.6%), higher in CPC 3 (31%) than CPC 4 (1.3%) patients, but not after 6 months from cardiac arrest. The median survival time after cardiac arrest was 386 days (95% confidence interval: 303-469). CONCLUSION Survival probability in patients with CPC 3 or 4 was 50% at 1-year and 20% at 3-year. Neurologic improvements were observed in 3.6% patients, higher in CPC 3 than in CPC 4 patients. During the first 6 months after OHCA, the neurologic status may improve in patients with CPC 3 or 4.

Int J Cardiol 2022; 364:1-8. [PMID: 35660557 DOI: 10.1016/j.ijcard.2022.06.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Revised: 05/15/2022] [Accepted: 06/01/2022] [Indexed: 11/17/2022]
Abstract
INTRODUCTION Coronary artery disease is a leading cause of out-of-the-hospital cardiac arrest (OHCA). However, there is no consensus on whether OHCA patients without ST-segment elevation (STE) benefit from emergent (ie < 2 h) coronary angiography (CAG). Our aim was to assess the impact of emergent CAG in no-STE OHCA patients. METHODS We performed a systematic review and meta-analysis by searching the MEDLINE, Cochrane, Scopus, CINAHL and JBI databases for randomized controlled trials (RCTs) comparing emergent CAG versus standard of care (ie CAG >2 h after OHCA or not performed) in no-STE OHCA patients of presumed cardiac aetiology. The primary outcome was short term survival. Secondary outcomes included survival with good neurological outcome, mid-term survival, left ventricle ejection fraction (LVEF), acute kidney injury (AKI) and renal replacement therapy (RRT), ventricular arrhythmias and major bleeding during hospital stay. RESULTS Seven RCTs met the inclusion and exclusion criteria and were included; one was included only in the analysis of mid-term survival and another in the LVEF analysis. Five studies (1278 patients, 643 with early CAG and 635 with no early CAG) were included in the analysis of the primary endpoint. The groups were balanced for all baseline characteristics but previous PCI, which was more frequent in the standard of care groups. There were no significant differences between groups for short-term survival (57 vs 61%; OR0.85, 95% CI0.68-1.07; I2 = 0%). There were also no differences for any of the secondary endpoints. CONCLUSION Routine emergent CAG did not improve survival in comatose survivors of OHCA with shockable rhythm and no-STE.

Abstract
Importance Data on long-term survival beyond 12 months after out-of-hospital cardiac arrest (OHCA) of a presumed cardiac cause are scarce. Objective To investigate the long-term survival of adult patients after surviving the initial hospital stay for an OHCA. Data Sources A systematic search of the EMBASE and MEDLINE databases was performed from database inception to March 25, 2021. Study Selection Clinical studies reporting long-term survival after OHCA were selected based on predefined inclusion and exclusion criteria according to a preregistered study protocol. Data Extraction and Synthesis Patient data were reconstructed from Kaplan-Meier curves using an iterative algorithm and then pooled to generate survival curves. As a separate analysis, an aggregate data meta-analysis was performed. Main Outcomes and Measures The primary outcome was long-term survival (>12 months) after OHCA for patients surviving to hospital discharge or 30 days after OHCA. Results The search identified 15 347 reports, of which 21 studies (11 800 patients) were included in the Kaplan-Meier-based meta-analysis and 33 studies (16 933 patients) in an aggregate data meta-analysis. In the Kaplan-Meier-based analysis, the median survival time for patients surviving to hospital discharge was 5.0 years (IQR, 2.3-7.9 years). The estimated survival rates were 82.8% (95% CI, 81.9%-83.7%) at 3 years, 77.0% (95% CI, 75.9%-78.0%) at 5 years, 63.9% (95% CI, 62.3%-65.4%) at 10 years, and 57.5% (95% CI, 54.8%-60.1%) at 15 years. Compared with patients with a nonshockable initial rhythm, patients with a shockable rhythm had a lower risk of long-term mortality (hazard ratio, 0.30; 95% CI, 0.23-0.39; P < .001). Different analyses, including an aggregate data meta-analysis, confirmed these results. Conclusions and Relevance In this comprehensive systematic review and meta-analysis, long-term survival after 10 years in patients surviving the initial hospital stay after OHCA was between 62% and 64%. Additional research is needed to understand and improve the long-term survival in this vulnerable patient population.

Clinical Validation of Cardiac Arrest Hospital Prognosis (CAHP) Score and MIRACLE2 Score to Predict Neurologic Outcomes after Out-of-Hospital Cardiac Arrest. Healthcare (Basel) 2022; 10:healthcare10030578. [PMID: 35327059 PMCID: PMC8950818 DOI: 10.3390/healthcare10030578] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Revised: 03/18/2022] [Accepted: 03/18/2022] [Indexed: 11/17/2022] Open
Abstract
Background. Out-of-hospital cardiac arrest (OHCA) remains a challenge for emergency physicians, given the poor prognosis. In 2020, MIRACLE2, a new and easier to apply score, was established to predict the neurological outcome of OHCA. Objective. The aim of this study is to compare the discrimination of MIRACLE2 score with cardiac arrest hospital prognosis (CAHP) score for OHCA neurologic outcomes. Methods. This retrospective cohort study was conducted between January 2015 and December 2019. Adult patients (>17 years) with cardiac arrest who were brought to the hospital by an emergency medical service crew were included. Deaths due to trauma, burn, drowning, resuscitation not initiated due to pre-ordered “do not resuscitate” orders, and patients who did not achieve return of spontaneous circulation were excluded. Receiver operating characteristic curve analysis with Youden Index was performed to calculate optimal cut-off values for both scores. Results. Overall, 200 adult OHCA cases were analyzed. The threshold of the MIRACLE2 score for favorable neurologic outcomes was 5.5, with an area under the curve (AUC) value of 0.70 (0.61−0.80, p < 0.001); the threshold of the CAHP score was 223.4, with an AUC of 0.77 (0.68−0.86, p < 0.001). On setting the MIRACLE2 score cut-off value, we documented 64.7% sensitivity (95% confidence interval [CI], 56.9−71.9%), 66.7.0% specificity (95% CI, 48.2−82.0%), 90.8% positive predictive value (PPV; 95% CI, 85.6−94.2%), and 27.2% negative predictive value (NPV; 95% CI, 21.4−33.9%). On establishing a CAHP cut-off value, we observed 68.2% sensitivity (95% CI, 60.2−75.5%), 80.6% specificity (95% CI, 62.5−92.6%), 94.6% PPV (95% CI, 88.6%−98.0%), and 33.8% NPV (95% CI, 23.2−45.7%) for unfavorable neurologic outcomes. Conclusions. The CAHP score demonstrated better discrimination than the MIRACLE2 score, affording superior sensitivity, specificity, PPV, and NPV; however, the CAHP score remains relatively difficult to apply. Further studies are warranted to establish scores with better discrimination and ease of application.

Impact of Pre-Revascularization and Post-Revascularization Cardiac Arrest on Survival Prognosis in Patients With Acute Myocardial Infarction and Following Emergency Percutaneous Coronary Intervention. Front Cardiovasc Med 2021; 8:705504. [PMID: 34869623 PMCID: PMC8639596 DOI: 10.3389/fcvm.2021.705504] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Accepted: 10/11/2021] [Indexed: 11/20/2022] Open
Abstract
Objectives: To evaluate the effects of occurrence and timing of sudden cardiac arrest (SCA) on survival in patients with acute myocardial infarction (AMI) who underwent emergency percutaneous coronary intervention (PCI). Methods: We analyzed 1,956 consecutive patients with AMI with emergency PCI from 2014 to 2018. Patients with cardiac arrest events were identified, and their medical records were reviewed. Results: Patients were divided into non-cardiac arrest group (NCA group, n = 1,724), pre-revascularization cardiac arrest (PRCA group, n = 175), and post-revascularization SCA (POCA group, n = 57) according to SCA timing. Compared to NCA group, PRCA group and POCA group presented with higher brain natriuretic polypeptide (BNP), more often Killip class 3/4, atrial fibrillation, and less often completed recovery of coronary artery perfusion (all p < 0.05). Both patients with PRCA and POCA showed increased 30-day all-cause mortality when compared to patients with NCA (8.0 and 70.2% vs. 2.9%, both p < 0.001). However, when compared to patients with NCA, patients with PRCA did not lead to higher mortality during long-term follow-up (median time 917 days) (16.3 vs. 18.6%, p = 0.441), whereas patients with POCA were associated with increased all-cause mortality (36.3 vs. 18.6%, p < 0.001). Multivariate analysis identified Killip class 3/4, atrial fibrillation, high maximum MB isoenzyme of creatine kianse, and high creatinine as predictive factors for POCA. In Cox regression analysis, POCA was found as a strong mortality-increase predictor (HR, 8.87; 95% CI, 2.26–34.72; p = 0.002) for long-term all-cause death. Conclusions: POCA appeared to be a strong life-threatening factor for 30-day and long-term all-cause mortality among patients with AMI who admitted alive and underwent emergency PCI. However, PRCA experience did not lead to a poorer long-term survival in patients with AMI surviving the first 30 days.

Effectiveness of fondaparinux vs unfractionated heparin following percutaneous coronary intervention in survivors of out-of-hospital cardiac arrest due to acute myocardial infarction. Eur J Clin Pharmacol 2021; 77:1563-1567. [PMID: 33963425 DOI: 10.1007/s00228-021-03152-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Accepted: 04/29/2021] [Indexed: 10/21/2022]
Abstract
AIM There is no specific evidence on the antithrombotic management of survivors of out-of-hospital cardiac arrest (OHCA) due to acute myocardial infarction (AMI). We sought to compare the short-term outcome of unfractioned heparin (UFH) vs fondaparinux in OHCA survivors due to AMI admitted in our Institution in the last decade. METHODS We performed a retrospective cohort study on survivors of OHCA due to AMI managed with UFH or fondaparinux during the hospitalization. The primary outcome was the occurrence of any bleeding, all-cause mortality, cerebrovascular accidents, re-MI, and unplanned revascularization at 1 month. A propensity-score matching was performed to compare the outcome between UFH and fondaparinux. RESULTS Out of 2083 AMI patients undergoing successful PCI, OHCA was present in 94 (4.5%): 41 (43.6%) treated with UFH and 53 (56.4%) with fondaparinux. At clinical follow-up, the incidence of the primary outcome was 65.9% in UFH and 35.8% in fondaparinux group (p = 0.007). More than half of the events included in the primary outcome were related to bleeding complications. In the matched cohort of 56 patients, the primary outcome occurred in 46.4% and 25.0% (p = 0.16), while bleeding was present in 32.1% and 7.1% (p = 0.04), in the UFH and fondaparinux group, respectively. CONCLUSIONS The present analysis suggests that fondaparinux is safer than UFH in the management of OHCA due to AMI by reducing early bleeding complications at one month.

Abstract
BACKGROUND Early coronary angiography (CAG) has been reported in individual studies and systematic reviews to significantly improve outcomes of patients with return of spontaneous circulation (ROSC) after cardiac arrest (CA). METHODS We undertook a systematic review and meta-analysis to evaluate the impact of early CAG on key clinical outcomes in comatose patients after ROSC following out-of-hospital CA of presumed cardiac origin. We searched the PubMED, EMBASE, CINAHL, ERIC and Cochrane Central Register of Controlled Trials databases from 1990 until April 2020. Eligible studies compared patients undergoing early CAG to patients with late or no CAG. When randomized controlled trials (RCTs) existed for a specific outcome, we used their results to estimate the effect of the intervention. In the absence of randomized data, we used observational data. We excluded studies at high risk of bias according to the Robins-I tool from the meta-analysis. The GRADE system was used to assess certainty of evidence at an outcome level. RESULTS Of 3738 citations screened, 3 randomized trials and 41 observational studies were eligible for inclusion. Evidence certainty across all outcomes for the RCTs was assessed as low. Randomized data showed no benefit from early as opposed to late CAG across all critical outcomes of survival and survival with favourable neurologic outcome for undifferentiated patients and for patient subgroups without ST-segment-elevation on post ROSC ECG and shockable initial rhythm. CONCLUSION These results do not support routine early CAG in undifferentiated comatose patients and patients without STE on post ROSC ECG after OHCA. REVIEW REGISTRATION PROSPERO - CRD42020160152.

Out-of-hospital cardiac arrest in patients treated for ST-elevation acute myocardial infarction: Incidence, clinical features, and prognosis based on population-level data from Hungary. Resusc Plus 2021; 6:100113. [PMID: 34223373 PMCID: PMC8244239 DOI: 10.1016/j.resplu.2021.100113] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Revised: 03/07/2021] [Accepted: 03/11/2021] [Indexed: 11/29/2022] Open
Abstract
Aim Out-of-hospital cardiac arrest (OHCA) is a severe complication of myocardial infarction. Literature data on the incidence of OHCA are inconsistent, and population-level data are incomplete. Methods Based on the Hungarian Myocardial Infarction Registry, the incidence of OHCA and its 30-day and 1-year mortality, as well as the significance of factors influencing the course of the disease in 28,083 ST-elevation myocardial infarction patients, were investigated using multivariable regression models. Results Of the 28,083 STEMI patients, 1535 (5.5%) had OHCA, which was more likely to occur in men. The long-term incidence of OHCA did not change significantly; no significant seasonality was found either. However, the daily distribution of cases showed that most OHCA patients were admitted to the hospital around 8 p.m. The occurrence of OHCA significantly worsened patients' prognoses; both 30-day and 1-year mortalities were considerably higher in the OHCA group than in the control group (46% vs 11.6%, 53.2% vs 18.7%, p < 0.001). This difference accumulated in the first few months; conditional survival after six months was no worse in those who had OHCA. Compared to those without OHCA, cardiogenic shock was more common at the time of hospitalisation (18.4% vs 2.2%) in the OHCA group. The highest risk of death was caused by the co-occurrence of OHCA and cardiogenic shock, which led to an eight times greater hazard of death (HR: 8.41, 95% CI: 7.37–9.60, p < 0.001). Conclusion Multivariable analysis confirmed the independent prognostic significance of age, catheter intervention during the index hospitalisation, OHCA, and cardiogenic shock.

Abstract
AIM Conduct a diagnostic test accuracy systematic review and meta-analysis of the post-return of spontaneous circulation (ROSC) electrocardiogram (ECG) to indicate an acute-appearing coronary lesion and revascularization. METHODS We searched PubMed, EMBASE, CINAHL, Cochrane Library, and Web of Science through February 18, 2020. Two investigators screened titles and abstracts, extracted data, and assessed risks of bias using QUADAS-2. We estimated sensitivity (Sn), specificity (Sp), and likelihood ratios (LR) for all reported ECG features to indicate all reported reference standards. Random-effects meta-analysis pooled comparable studies without critical risk of bias. GRADE methodology evaluated the certainty of evidence. RESULTS Overall, 48 studies reported 94 combinations of ECG features and reference standards with wide variation in their definitions. Most studies had risks of bias from selection for coronary angiography and blinding to the ECG and/or reference standard. Meta-analysis combined 6 studies for STE and acute coronary lesion (Sn 0.70 [95% CI 0.54-0.82]; Sp 0.85 [95% CI 0.78-0.90]; LR + 4.7 [95% CI 3.3-6.7]; LR- 0.4 [95% CI 0.2-0.6]) and 4 studies for STE and revascularization (Sn 0.53 [95% CI 0.47-0.58]; Sp 0.86 [95% CI 0.80-0.91]; LR + 3.9 [95% CI 2.8-5.5]; LR- 0.5 [95% CI 0.5-0.6]). Overall certainty of evidence was low with substantial heterogeneity. CONCLUSIONS Based on low certainty evidence, STE had good classification for acute coronary lesion and fair classification for revascularization. STE was more specific than sensitive for these outcomes and no single ECG feature excluded them. Uniform definitions and terminology would greatly facilitate the interpretation of subsequent studies.

Abstract
OBJECTIVE This meta-analysis aimed to review the available evidence and evaluate the necessity of immediate coronary angiography (CAG) to obtain positive outcomes for out-of-hospital cardiac arrest (OHCA) patients without ST segment elevation. DATA SOURCES Web of Science, PubMed, Embase, Chinese National Knowledge Infrastructure, Wanfang, and SinoMed databases. STUDY SELECTION We included observational and case-control studies of outcomes among individuals without ST segment elevation experiencing OHCA who had immediate, delayed, or no CAG. DATA EXTRACTION We extracted study details, as well as patient characteristics and outcomes. DATA SYNTHESIS Six studies (n = 2665) investigating mortality until discharge demonstrated a significant increase in survival benefit with early CAG (odds ratio [OR] = 1.78; 95%CI = 1.51-2.11; I = 81%; P < .0001). Seven studies (n = 2909) showed a significant preservation of neurological functions with early CAG at discharge (OR = 1.66; 95%CI = 1.37-2.02; P < .00001). Four studies (n = 1357) investigating survival outcomes with middle-term follow-up revealed no significant benefit with early CAG (OR = 1.21; 95%CI = 0.93-1.57; I = 66%; P = .15). CONCLUSIONS Our meta-analysis demonstrates that there may be significant benefits in performing immediate CAG on patients who experience OHCA without ST segment elevation.

Abstract
AIM Patients that experience an out-of-hospital cardiac arrest in the context of a paramedic-identified ST-segment elevation myocardial infarction are a unique cohort. This study identifies the survival outcomes and determinants of survival in these patients. METHODS A retrospective analysis was undertaken of all patients, attended between 1 January 2013 and 31 December 2017 by the Queensland Ambulance Service, who had a ST-segment elevation myocardial infarction identified by the attending paramedic prior to deterioration into out-of-hospital cardiac arrest. We described the 'survived event' and 'survived to discharge' outcomes of patients and performed univariate analysis and multivariate logistic regression to identify factors associated with survival. RESULTS In total, 287 patients were included. Overall, high rates of survival were reported, with 77% of patients surviving the initial out-of-hospital cardiac arrest event and 75% surviving to discharge. Predictors of event survival were the presence of an initial shockable rhythm (adjusted odds ratio 8.60, 95% confidence interval (CI) 4.16-17.76; P < 0.001) and the administration of prehospital medication for subsequent primary percutaneous coronary intervention (adjusted odds ratio 2.54, 95% CI 1.17-5.50; P = 0.020). These factors were also found to be associated with survival to hospital discharge, increasing the odds of survival by 13.74 (95% CI 6.02-31.32; P < 0.001) and 6.96 (95% CI 2.50-19.41; P < 0.001) times, respectively. The administration of prehospital fibrinolytic medication was also associated with survival in a subgroup analysis. CONCLUSION This subset of out-of-hospital cardiac arrest patients was found to be highly salvageable and responsive to resuscitative measures, having arrested in the presence of paramedics and presented with an identified reversible cause.

Abstract
Background: Data on acute kidney injury (AKI) in patients with myocardial infarction (MI) who underwent percutaneous coronary intervention (PCI) after cardiac arrest are scarce. The prevalence of AKI, as classified by the Kidney Disease: Improving Global Outcomes (KDIGO) criteria; and its possible association with 30-day mortality were assessed. Methods: Data on 6387 patients with MI, 342 (5.3%) with out-of-hospital cardiac arrest or arrest immediately after admission before PCI, were retrospectively analyzed. The AKI and no-AKI groups were compared. The 30-day mortality was determined. Results: Ninety-three (27.2%) patients suffered AKI. AKI KDIGO stages 1, 2 and 3 occurred in 45 (13.2%), 8 (2.3%) and 40 (11.7%) patients, respectively. Higher mortality was found in AKI patients [56 (60.2%) vs. no-AKI patients 32 (12.9%); p<0.0001]. More patients died in the higher AKI KDIGO stages. In AKI KDIGO stages 1/2 and stage 3, 20 (37.7%) patients and 36 (90.0%) patients died, respectively compared to 32 (12.9%) no-AKI patients; p<0.0001. AKI was the strongest predictor of 30-day mortality (adjusted OR 6.98; 95% CI 3.42 to 14.23; p<0.0001). Other predictors were bleeding, cardiogenic shock, contrast volume-to-glomerular filtration rate ratio, and female sex. The adjusted OR for AKI KDIGO stages 1/2 and stage 3 were 3.68; 95% CI 1.53 to 8.32; p=0.002 and 29.10; 95% CI 8.31 to 101.88; p<0.0001, respectively. Conclusion: In patients resuscitated after MI undergoing PCI, AKI had a deleterious impact on the prognosis. A graded increase in the severity of AKI according to the KDIGO definition was associated with a progressively increased risk of 30-day mortality.

Abstract
Out-of-hospital cardiac arrest (OHCA) is an important cause of mortality and morbidity in developed countries and remains an important public health burden. A primary cardiac aetiology is common in OHCA patients, and so patients are increasingly brought to specialist cardiac centres for consideration of coronary angiography, percutaneous coronary intervention and mechanical circulatory support. This article focuses on the management of OHCA in the cardiac catheterisation laboratory. In particular, it addresses conveyance of the OHCA patient direct to a specialist centre, the role of targeted temperature management, pharmacological considerations, provision of early coronary angiography and mechanical circulatory support.

Abstract
Introduction As coronary artery disease is the most frequent cause of cardiac arrest, early invasive strategies may be beneficial for such patients. This study analyses the impact of in-hospital treatment on short-term outcomes of out-of-hospital cardiac arrest (OHCA) survivors. Material and methods Patients admitted to the Cardiac Intensive Care Unit of our hospital within 2-year period were prospectively included in the study. Results One hundred thirty-one patients were included in the study, which showed that in-hospital mortality increases uniformly with the severity of the coronary artery lesion (p = 0.044), but an effect of revascularization on number of deaths was not observed (p = 0.64). The presence of coma (p = 0.005) and the combination of male sex and age above 60-year as 2.2-fold (p = 0.048) increasing in-hospital mortality were found. The highest mortality rate occurred during the first 3 days and the death rate of the patients who survived this period is low. We found reduced left ventricular ejection fraction (OR = 6.54; 95% CI: 1.98-21.63; p = 0.002), non-ventricular fibrillation initial rhythm (OR = 2.94; 95% CI: 1.25-6.90; p = 0.014), unconscious at admission (OR = 6.46; 95% CI: 1.96-21.24; p = 0.002) and post-resuscitation coma (OR = 6.00; 95% CI: 2.63-13.66; p < 0.001) or encephalopathy (OR = 2.71; 95% CI: 1.9-6.72; p = 0.031) to be significant prognostic factors for higher in-hospital mortality rate. Conclusions We recommend immediate coronary interventions for all survivors of OHCA regardless of their state of consciousness and absence of ischaemic changes on ECG. Early intensive treatment for OHCA patients is indispensable, as the highest mortality rate is within the first 3 days after an event.

Abstract
BACKGROUND: Over the past decade, prehospital and in-hospital treatment for out-of-hospital cardiac arrest (OHCA) has improved considerably. There are sparse data on the long-term outcome, especially in elderly patients. We studied whether elderly patients benefit to the same extent compared with younger patients and at long-term follow up as compared with the general population. METHODS: Between 2001 and 2010, data from all patients presented to our hospital after OHCA were recorded. Elderly patients (⩾75 years) were compared with younger patients. Neurological outcome was classified as cerebral performance category (CPC) at hospital discharge and long-term survival was compared with younger patients and predicted survival rates of the general population. RESULTS: Of the 810 patients admitted after OHCA, a total of 551 patients (68%) achieved return of spontaneous circulation, including 125 (23%) elderly patients with a mean age of 81 ± 5 years. In-hospital survival was lower in elderly patients compared with younger patients with rates of 33% versus 57% ( p < 0.001). A CPC of 1 was present in 73% of the elderly patients versus 86% of the younger patients ( p = 0.031). In 7.3% of the elderly patients, a CPC >2 was observed versus 2.5% of their younger counterparts ( p = 0.103). Elderly patients had a median survival of 6.5 [95% confidence interval (CI) 2.0-7.9] years compared with 7.7 (95% CI 7.5-7.9) years of the general population ( p = 0.019). CONCLUSIONS: The survival rate after OHCA in elderly patients is approximately half that of younger patients. Elderly patients who survive to discharge frequently have favorable neurological outcomes and a long-term survival that approximates that of the general population.

Abstract
BACKGROUND: The development of cardiac arrhythmias resulting in cardiac arrest represents a severe complication in patients with acute myocardial infarction. While the worsening of the prognosis in this vulnerable patient collective is well known, less attention has been paid to its age-specific relevance from a long-term perspective. METHODS: Based on a clinical acute myocardial infarction registry we analysed 832 patients with acute myocardial infarction within the current analysis. Patients were stratified into equal groups ( n=208 per group) according to age in less than 45 years, 45-64 years, 65-84 years and 85 years and older via propensity score matching. Multivariate Cox regression analysis was used to assess the age-dependent influence of cardiac arrest on mortality. RESULTS: The total number of cardiac arrests differed significantly between age groups, demonstrating the highest incidence in the youngest population with 18.8% ( n=39), and a significantly lower incidence by increasing age (-11.6%; P=0.01). After a mean follow-up time of 8 years, a total of 264 patients (31.7%) died due to cardiovascular causes. While cardiac arrest was a strong and independent predictor for mortality within the total study population with an adjusted hazard ratio of 3.21 (95% confidence interval 2.23-4.61; P<0.001), there was no significant association with mortality independently in very young patients (<45 years; adjusted hazard ratio of 1.73, 95% confidence interval 0.55-5.53; P=0.35). CONCLUSION: We found that arrhythmias resulting in cardiac arrest are more common in very young acute myocardial infarction patients (<45 years) compared to their older counterparts, and were able to demonstrate that the prognostic value of cardiac arrest on long-term mortality in patients with acute myocardial infarction is clearly age dependent.

Abstract
BACKGROUND In patients with out-of-hospital cardiac arrest who achieve return of spontaneous circulation, coronary angiography (CAG) might improve outcomes. We conducted a systematic review and meta-analysis to elucidate the benefit and optimal timing of early CAG in comatose out-of-hospital cardiac arrest patients with return of spontaneous circulation. METHODS We searched MEDLINE, EMBASE, and Cochrane from 1990 to May 2017. Studies reporting survival and/or neurological survival in early (< 24-hour) vs late/no CAG were selected. We used the Clinical Advances Through Research and Information Translation (CLARITY) risk of bias in cohort studies tool and Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) criteria to assess risk of bias and quality of evidence, respectively. Results were pooled using random effects and presented as risk ratios (RRs) with 95% confidence intervals (CIs). RESULTS After screening 9185 titles/abstracts and 631 full-text articles, we included 23 nonrandomized studies. Short (to discharge or 30 days) and long-term (1-5 years) survival were significantly improved (52% and 56%, respectively) in the early < 24-hour CAG group compared with the late/no CAG group (RR, 1.52; 95% CI, 1.32-1.74; P < 0.00001; I2, 94% and RR, 1.56; 95% CI, 1.14-2.14; P = 0.006; I2, 86%). Survival with good neurological outcome was also improved by 69% in the < 24-hour CAG group at short- (RR, 1.69; 95% CI, 1.40-2.04; P < 0.00001; I2, 93%) and intermediate-term (3-11 months; RR, 1.49; 95% CI, 1.27-1.76; P < 0.00001; I2, 67%). We found consistent benefits in the < 2-hour and < 6-hour subgroups. Early CAG was associated with significantly better outcomes in studies of patients without ST-elevation, but the results did not reach statistical significance in studies of patients with ST-elevation. CONCLUSIONS On the basis of very low quality, but consistent evidence, early CAG (< 24 hours) was associated with significantly higher survival and better neurologic outcomes.

Abstract
AIM To compare short- and long-term survival in patients admitted to hospital after acute myocardial infarction (AMI) with and without out-of-hospital cardiac arrest (OHCA). METHODS Prospective cohort study of all AMI patients admitted to Oslo University Hospital Ulleval from September 1, 2005 to December 31, 2011. All-cause mortality was obtained from the Norwegian Cause of Death Registry with censoring date December 31, 2013. Cumulative survival was assessed with the Kaplan-Meier and the Life-table method. Logistic- and Cox regression were used for risk comparisons. RESULTS We identified 404 AMI patients with OHCA and 9425 AMI patients without. AMI patients without OHCA were categorized as ST-elevation myocardial infarction (STEMI, n=4522) or non-STEMI (NSTEMI, n=4903). Mean age was 63.6±standard deviation (SD) 12.5, 63.8±13.1 and 69.7±13.6 years in OHCA, STEMI and NSTEMI, respectively. Coronary angiography with subsequent percutaneous coronary intervention if indicated, was performed in 87% of OHCA, 97% of STEMI and 80% of NSTEMI patients. Thirty-day survival was 63%, 94% and 94%, and 8-year survival was 49%, 74%, and 57%, respectively. Among patients surviving the first 30days, no significant difference in risk during long-term follow-up was found (adjusted Hazard Ratio (aHR)OHCAvsSTEMI 1.15 [95% CI 0.82-1.60], aHROHCAvsNSTEMI 0.89 [95% CI 0.64-1.24]). CONCLUSIONS Long-term survival after OHCA due to AMI was good, with 49% of admitted patients being alive after eight years. Although short-term mortality remained high, OHCA patients alive after 30days had similar long-term risk as AMI patients without OHCA.

Abstract
Objectives Current prognostication guidelines for cardiac arrest (CA) survivors predate the use of therapeutic hypothermia (TH). The prognostic value and ideal timing of the neurological examination remain unknown in the setting of TH. Design Patients (N = 291) admitted between 2007 and 2015 to Columbia University intensive care units for TH following CA had neurological examinations performed on days 1, 3, 5, and 7 postarrest. Absent pupillary light response (PLR), absent corneal reflexes (CRs), and Glasgow coma scores motor (GCS-M) no better than extension were considered poor examinations. Poor outcome was recorded as cerebral performance category score ≥3 at discharge and 1 year. Predictive values of examination maneuvers were calculated for each time point. Main Results Among the 137 survivors to day 7, sensitivities and negative predictive values were low at all time points. The PLR had false positive rates (FPRs) of 0% and positive predictive values (PPV) of 100% from day 3 onward. For the CR and GCS-M, the FPRs decreased from day 3 to 5 (9% vs 3%; 21% vs 9%), while PPVs increased (91% vs 96%; 90% vs 95%). Excluding patients who died due to withdrawal of life-sustaining therapy (WLST) did not significantly affect FPRs or PPVs, nor did assessing outcome at 1 year. Conclusions A poor neurological examination remains a strong predictor of poor outcome, both at hospital discharge and at 1 year, independent of WLST. Following TH, the predictive value of the examination is insufficient at day 3 and should be delayed until at least day 5, with some additional benefit beyond day 5.

Abstract
INTRODUCTION The Institute of Medicine and American Heart Association have called for tiered accreditation standards and regionalization of post-cardiac arrest care, but there is little data to support that regionalization has a durable effect on patient outcomes. We tested the effect of treatment at a high-volume center on long-term outcome after sudden cardiac arrest (SCA). METHODS We included patients hospitalized at one of 7 medical centers in Southwestern Pennsylvania after SCA from 2005 to 2013. Centers were one regional referral center with an organized systems for post-SCA care, two moderate volume tertiary care centers and 4 low-volume centers. We abstracted clinical characteristics and outcomes at hospital discharge, and for survivors to discharge we queried the National Death Index for long-term survival data. We used Cox regression to determine the unadjusted associations of baseline predictors and survival, and built an adjusted model controlling for baseline predictors. RESULTS Overall, 987 patients survived to discharge. During 2196 person-years of follow-up, median survival was 5.3 years and there were 396 deaths. In unadjusted analysis, treating center, age, arrest location, Charlson Comorbidity Index, initial rhythm, cardiac catheterization, defibrillator placement, discharge disposition, and neurological status at discharge were associated with long-term outcome. In adjusted analysis, treatment at the high-volume cardiac arrest center was associated with improved survival compared to treatment at other centers (hazards ratio 1.49, 95% confidence interval 1.19-1.86). CONCLUSION Treatment at a high-volume cardiac arrest center with organized systems for post-arrest care is associated with a substantial long-term survival benefit after hospital discharge.
