Use of smartphone app in cardiac-arrest response: higher survival rate, no cost increase

Abstract Background Mechanical circulatory support (MCS) with either extracorporeal membrane oxygenation or Impella has shown potential as a salvage therapy for patients with refractory out-of-hospital cardiac arrest (OHCA). The objective of this study was to describe the gradual implementation, survival and adherence to the national consensus with respect to use of MCS for OHCA in Denmark, and to identify factors associated with outcome. Methods This retrospective, observational cohort study included patients receiving MCS for OHCA at all tertiary cardiac arrest centers (n = 4) in Denmark between July 2011 and December 2020. Logistic regression and Kaplan–Meier survival analysis were used to determine association with outcome. Outcome was presented as survival to hospital discharge with good neurological outcome, 30-day survival and predictors of 30-day mortality. Results A total of 259 patients were included in the study. Thirty-day survival was 26%. Sixty-five (25%) survived to hospital discharge and a good neurological outcome (Glasgow–Pittsburgh Cerebral Performance Categories 1–2) was observed in 94% of these patients. Strict adherence to the national consensus showed a 30-day survival rate of 30% compared with 22% in patients violating one or more criteria. Adding criteria to the national consensus such as signs of life during cardiopulmonary resuscitation (CPR), pre-hospital low-flow < 100 min, pH > 6.8 and lactate < 15 mmol/L increased the survival rate to 48%, but would exclude 58% of the survivors from the current cohort. Logistic regression identified asystole (RR 1.36, 95% CI 1.18–1.57), pulseless electrical activity (RR 1.20, 95% CI 1.03–1.41), initial pH < 6.8 (RR 1.28, 95% CI 1.12–1.46) and lactate levels > 15 mmol/L (RR 1.16, 95% CI 1.16–1.53) as factors associated with increased risk of 30-day mortality. Patients presenting signs of life during CPR had reduced risk of 30-day mortality (RR 0.63, 95% CI 0.52–0.76). Conclusions A high survival rate with a good neurological outcome was observed in this Danish population of patients treated with MCS for OHCA. Stringent patient selection for MCS may produce higher survival rates but potentially withholds life-saving treatment in a significant proportion of survivors.

Background: Impella CP is a left ventricular pump which may serve as a circulatory support during cardiopulmonary resuscitation (CPR) for cardiac arrest (CA). Nevertheless, the survival rate and factors associated with survival in patients undergoing Impella insertion during CPR for CA are unknown. Methods: We performed a retrospective multicenter international registry of patients undergoing Impella insertion during on-going CPR for in- or out-of-hospital CA. We recorded immediate and 30-day survival with and without neurologic impairment using the cerebral performance category score and evaluated the factors associated with survival. Results: Thirty-five patients had an Impella CP implanted during CPR for CA. Refractory ventricular arrhythmias were the most frequent initial rhythm (65.7%). In total, 65.7% of patients immediately survived. At 30 days, 45.7% of patients were still alive. The 30-day survival rate without neurological impairment was 37.1%. In univariate analysis, survival was associated with both an age < 75 years and a time from arrest to CPR ≤ 5 min (p = 0.035 and p = 0.008, respectively). Conclusions: In our multicenter registry, Impella CP insertion during ongoing CPR for CA was associated with a 37.1% rate of 30-day survival without neurological impairment. The factors associated with survival were a young age and a time from arrest to CPR ≤ 5 min.

Cardiac arrest (CA) is associated with high mortality and poor life quality. Targeted temperature management (TTM) or therapeutic hypothermia is a therapy increasing the survival of adult patients after CA. The study aim was to assess the feasibility of therapeutic hypothermia after pediatric CA. We performed a systematic review and meta-analysis of randomized controlled trials and observational studies evaluating the use of TTM after pediatric CA. The primary outcome was survival to hospital discharge or 30-day survival. Secondary outcomes included a one-year survival rate, survival with a Vineland adaptive behavior scale (VABS-II) score ≥ 70, and occurrence of adverse events. Ten articles (n = 2002 patients) were included, comparing TTM patients (n = 638) with controls (n = 1364). In a fixed-effects meta-analysis, survival to hospital discharge in the TTM group was 49.7%, which was higher than in the non-TTM group (43.5%; odds ratio, OR = 1.22; 95% confidence interval, CI: 1.00, 1.50; p = 0.06). There were no differences in the one-year survival rate or the occurrence of adverse events between the TTM and non-TTM groups. Altogether, the use of TTM was associated with a higher survival to hospital discharge; however, it did not significantly increase the annual survival. Additional high-quality prospective studies are necessary to confer additional TTM benefits.

Coronary Syndrome

Introduction: Idiopathic ventricular fibrillation (IVF) including Brugada syndrome (BS) is one of causes of cardiac arrest without prior overt cardiac dysfunction. Hypothesis: We assessed the hypothesis that patents of IVF had favor outcomes than those of non-IVF after cardiac arrest treated with targeted temperature management (TTM). Methods: Patients who were treated with TTM after cardiac arrest between 2000 and 2019 were enrolled in the study. Patients were divided into 2 groups according to whether the patients were diagnosed as IVF or not. The patients treated with TTM were routinely performed coronary angiography. Results: Among the study patients (N = 306), 35 (11%) patients were IVF and 7 were BS. The patients of the IVF group were significantly younger (median 53 y vs. 64 y) than those of the non-IVF group. The prevalence of initial rhythm was shockable (69% vs. 47%, P = 0.02) was significantly higher in the patients of the IVF group than those of the non-IVF group. Among the patients in the non-IVF group, 114 patients (42%) were diagnosed as acute coronary syndrome and 93 patients (35%) were treated with coronary revascularization. The prevalence of male sex (77% vs 74%, P = 0.70) and witnessed to arrest (80% vs. 81%, P = 0.87), and low-flow time (29 min vs. 38 min [20 - 43 min vs. 21 - 52 min, P = 0.15]) were similar between the 2 groups. The prevalence of performing extracorporeal resuscitation (9% s 43%, P < 0.001) were lower in the patients of the IVF group. The 8-y survival rate were shown in the figure. All of the BS patients were witnessed arrest and were discharged without severe neurological deficit. The IVF as the cause of arrest was independently associated with 8-y survival. Conclusions: The patients of IVF had favor outcomes than those of non-VF. One of causes may be the lower prevalence of requiring extracorporeal circulatory support due to less cardiac dysfunction. The patients of BS had the tendency toward higher survival rate than those of non-BS IVF patients.

Background: In Japan, extracorporeal cardiopulmonary resuscitation (ECPR) became popular for cardiac arrest patients who resist conventional advanced life supports. Regardless of many clinical experiences, there has been no previous systematic literature review. Methods: Case series, reports and proceedings of scientific meeting about ECPR for out-of-hospital cardiac arrest written in Japanese between January 1, 1983 and July 31, 2007 were collected with Japana Centra Revuo Medicina (medical publication database in Japan) and review by experts. The outcome and characteristics of the patients were investigated, and the influence of publication bias of the case series study was also examined by the Funnel Plot method. Results: There were 951 out-of-hospital cardiac arrest patients who received ECPR in 92 reports (including 59 case series and 33 case reports) during the period. The average of age was 38.1 (4 – 88) years old and 76.1% was male. Three hundreds and eighty-one cases (40.1%) were arrests of cardiac etiology, and 212 were non-cardiac (22.3%). The cause of arrest was not described in other 37.6%. Excluding reports for only one case, weighted survival rate at discharge of 792 cases those were clearly described the outcome was 39.5±10.0%. When the relationship between the number of cases and the survival rate at discharge in each 59 case series study was shown in figure by the Funnel Plot method, the plotted data presented the reverse-funnel type that centered on the average of survival rate of all. Conclusions: The influence of publication bias of previous reports in Japan was relatively low. ECPR can greatly contribute to improve the outcome of out-of hospital cardiac arrests.

The role of glycocalyx in blood–brain barrier (BBB) integrity and brain damage is poorly understood. Our study aimed to investigate the impacts of endothelial glycocalyx on BBB function in a rat model of cardiac arrest (CA) and cardiopulmonary resuscitation (CPR). Male Sprague-Dawley rats subjected to 8-min asphyxia CA/CPR. Compared to controls, glycocalyx was mildly injured by CA, severely disrupted by hyaluronidase (HAase) with CA, and mitigated by hydrocortisone (HC) with CA. More importantly, the disruption of glycocalyx caused by HAase treatment was associated with higher BBB permeability and aggravated brain edema at 24 h after return of spontaneous circulation, as well as lower survival rate and poorer neurologic outcome at seventh day. Reversely, less degradation of glycocalyx by HC treatment was accompanied by higher seven-day survival rate and better neurologic outcome. Mechanistically, HAase treatment further increased CA/CPR-induced activation of glia cells and expression of inflammatory factors, whereas HC decreased them in the brain cortex and hippocampus. Glycocalyx degradation results in BBB leakage, brain edema, and deteriorates neurologic outcome after asphyxia CA/CPR in rats. Preservation of glycocalyx by HC could improve neurologic outcome and reduce BBB permeability, apparently through reduced gene transcription-protein synthesis and inflammation.

Hospital Cardiac Arrest

Background: For patients with in-hospital cardiac arrests due to non-shockable rhythms, delays in epinephrine administration beyond 5 minutes is associated with worse survival. However, the extent of hospital variation in delayed epinephrine administration and its impact on hospital-level outcomes is unknown. Methods: Within Get with the Guidelines-Resuscitation, we identified 103,932 adult patients (>18 years) at 548 hospitals with an in-hospital cardiac arrest due to a non-shockable rhythm who received at least 1 dose of epinephrine between 2000 to 2014. We constructed two-level hierarchical regression models to quantify hospital variation in rates of delayed epinephrine administration (>5 minutes) and its association with hospital rates of survival to discharge. Results: Among the 548 hospitals, there was substantial variation in rates of delayed epinephrine administration (median 13.5%, range: 0%- 53.8%). The odds of delay in epinephrine administration were 61% higher at one randomly selected hospital compared to a similar patient at another randomly selected hospitals (median odds ratio [OR] 1.61; 95% C.I. 1.54 - 1.67). After adjusting for patient characteristics, the median risk-standardized survival rate for non-shockable in-hospital cardiac arrests was 12.1% and varied significantly across hospitals (range: 5.2% to 30.9%). There was an inverse correlation between a hospital’s rate of delayed epinephrine administration and its risk-standardized survival rate for cardiac arrests due to non-shockable rhythm (ρ= -0.23, P<0.0001). Compared to hospitals in the best quartile, risk-standardized survival was 17.4% lower at hospitals in the worst quartile of delayed epinephrine administration (13.8% vs. 11.4%, P<0.0001, Figure). Conclusions: Although delays in epinephrine administration following in-hospital cardiac arrest are common, there is substantial hospital variation in rates of delayed epinephrine administration. Hospitals with high rates of delayed epinephrine administration were found to have lower rates of risk-adjusted survival. Further studies are needed to determine if improving hospital performance on time to epinephrine administration, especially at hospitals with poor performance on this metric will lead to improvement in outcomes.

Hospital Cardiac Arrest

Background and Objectives: It is estimated that over 200,000 adults experience in-hospital cardiac arrest each year. Overall survival to discharge has remained relatively unchanged for decades and survival rates remain at about 20% (Elenbach et al., 2009). Get With The Guidelines-Resuscitation (GWTG-R) is an in-hospital quality improvement program designed to improve adherence to evidence-based care of patients who experience an in-hospital resuscitation event. GWTG-R focuses on four achievement measures. The measures for adult patients include time to first chest compression of less than or equal to one minute, device confirmation of correct endotracheal tube placement, patients with pulseless VF/VT as the initial documented rhythm with a time to first shock of less than or equal to two minutes, and events in which patients were monitored or witnessed at the time of cardiac arrest. The objective of this abstract is to examine the association between hospital adherence to GWTG-R and in-hospital cardiac arrest survival rates. Methods: A retrospective review of adult in-hospital cardiopulmonary arrest (CPA) patients (n=1849) from 21 Michigan, Illinois, and Indiana hospitals using the GWTG-R database was conducted from January 2014 through December 2014. This study included adult CPA patients that did and did not survive to discharge. Results: The review found that hospitals that had attained 84.6% or higher thresholds in all four achievement measures for at least one year, which is award recognition status, had a significantly improved in-hospital CPA survival to discharge rate of 29.6%. Hospitals that did not obtain award status had a CPA survival to discharge rate of 24.3%. The national survival rate for in-hospital adult CPA survival to discharge is 20%. Hospitals that did not achieve award recognition status still demonstrated improvement in survival rate when compared to the national survival rate, indicating the importance of a quality improvement program such as GWTG-R. No significant difference was found between in-hospital adult CPA survival rate and race between GWTG-R award winning and non-award winning hospitals. Hospitals that earned award recognition from GWTG-R had a survival to discharge rate of 30.2% for African Americans and 29.6% for whites. Hospitals that were did not earn award recognition from GWTG-R had a survival to discharge rate of 20.0% for African Americans and 20.1% for whites. Conclusions: Survival of in-hospital adult CPA patients improved significantly when GWTG-R measures are adhered to. Survival of in-hospital adult CPA patients also improves with implementation of GWTG-R. It is crucial that hospitals collect and analyze data regarding resuscitation processes and outcomes. Quality improvement measures can then be implemented in order to assist with improving in-hospital CPA survival rates.

Purpose. We investigated the protective effects and the underlying mechanisms through which recombinant human brain natriuretic peptide (rhBNP) acts on postresuscitation myocardial dysfunction (PRMD) in the cardiac arrest (CA) model. Methods. Ventricular fibrillation was induced and untreated for 6 min. And the time of cardiopulmonary resuscitation was 8 min, after which defibrillation was attempted in this rat model. 24 Sprague Dawley rats (450–550g) were randomized into cardiopulmonary resuscitation (CPR) + rhBNP and CPR + placebo groups after restoration of spontaneous circulation (ROSC). rhBNP was infused at PR 30 min (loading dose: 1.5 µg/kg, 3 min; maintenance dose: 0.01 µg/kg/min, 6 h). Vital signs, ejection fraction (EF), cardiac output (CO), myocardial performance index (MPI), and 24 h survival rate were continuously recorded. The serum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and N-terminal probrain natriuretic peptide (NT-proBNP) were detected by ELISA. Heart tissues were evaluated by light microscopy. The protein expression levels of myocardial inflammatory factors (IL-6 and TNF-α), Toll-like receptor 4 (TLR4), nuclear transcription factor-κB (NF-κB) subunit p65 (p65), and phosphor-p65 were analyzed by western blotting. Results. The administration of rhBNP attenuated the severity of PRMD and myocardial tissue injuries, with improvement of MAP (mean arterial blood pressure), ETCO2 (end-tidal CO2), serum level of NT-proBNP, EF, CO, and MPI values. The serum levels and protein expression levels in myocardial tissue of IL-6 and TNF-α after ROSC were reduced by inhibiting the expression of TLR4/NF-κB. Conclusion. Our research demonstrated that the administration of rhBNP attenuated the severity of PRMD and myocardial tissue injuries and increased the 24 h survival rate in this CA model. rhBNP administration also reduced the serum and myocardial tissue levels of IL-6 and TNF-α after ROSC, likely due to the suppression of the TLR4/NF-κB signaling pathway and the regulation of inflammatory mediator secretion.
