Abstract
OBJECTIVE To determine temporal trends in the incidence of cardiac arrest occurring in the ICU (ICU-CA) and its associated long-term mortality. DESIGN Retrospective observational study. SETTING Swedish ICUs, between 2011 and 2017. PATIENTS Adult patients (≥18 yr old) recorded in the Swedish Intensive Care Registry (SIR). INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS ICU-CA was defined as a first episode of cardiopulmonary resuscitation and/or defibrillation following an ICU admission, as recorded in SIR or the Swedish Cardiopulmonary Resuscitation Registry. Annual adjusted ICU-CA incidence trend (all admissions) was estimated using propensity score-weighted analysis. Six-month mortality trends (first admissions) were assessed using multivariable mixed-effects logistic regression. Analyses were adjusted for pre-admission characteristics (sex, age, socioeconomic status, comorbidities, medications, and healthcare utilization), illness severity on ICU admission, and admitting unit. We included 231,427 adult ICU admissions. Crude ICU-CA incidence was 16.1 per 1,000 admissions, with no significant annual trend in the propensity score-weighted analysis. Among 186,530 first admissions, crude 6-month mortality in ICU-CA patients was 74.7% (95% CI, 70.1-78.9) in 2011 and 68.8% (95% CI, 64.4-73.0) in 2017. When controlling for multiple potential confounders, the adjusted 6-month mortality odds of ICU-CA patients decreased by 6% per year (95% CI, 2-10). Patients admitted after out-of-hospital or in-hospital cardiac arrest had the highest ICU-CA incidence (136.1/1,000) and subsequent 6-month mortality (76.0% [95% CI, 73.6-78.4]). CONCLUSIONS In our nationwide Swedish cohort, the adjusted incidence of ICU-CA remained unchanged between 2011 and 2017. More than two-thirds of patients with ICU-CA did not survive to 6 months following admission, but a slight improvement appears to have occurred over time.

Abstract
BACKGROUND Cardiac arrest in intensive care is a rarely studied type of in-hospital cardiac arrest. OBJECTIVE This study examines the incidence, characteristics, risk factors for mortality as well as long-term prognosis following cardiac arrest in intensive care. DESIGN Retrospective cohort study. SETTING Five noncardiac surgical ICUs (41 surgical and 37 medical beds) at a German university hospital between 2016 and 2019. PATIENTS Adults experiencing cardiac arrest defined as the need for chest compressions and/or defibrillation occurring for the first time on the ICU. MAIN OUTCOME MEASURES Primary endpoint: occurrence of cardiac-arrest in the ICU. Secondary endpoints: diagnostic and therapeutic measures; risk factors and marginal probabilities of no-return of spontaneous circulation; rates of return of spontaneous circulation, hospital discharge, 1-year-survival and 1-year-neurological outcome. RESULTS A total of 114 cardiac arrests were observed out of 14 264 ICU admissions; incidence 0.8%; 95% confidence interval (CI) 0.7 to 1.0; 45.6% received at least one additional diagnostic test, such as blood gas analysis (36%), echocardiography (19.3%) or chest x-ray (9.9%) with a resulting change in therapy in 52%, (more frequently in those with a return of spontaneous circulation vs none, P = 0.023). Risk factors for no-return of spontaneous circulation were cardiac comorbidities (OR 5.4; 95% CI, 1.4 to 20.7) and continuous renal replacement therapy (OR 5.9; 95% CI, 1.7 to 20.8). Bicarbonate levels greater than 21 mmol l-1 were associated with a higher mortality risk in combination either with cardiac comorbidities (bicarbonate <21 mmol l-1: 13%; 21 to 26 mmol l-1: 45%; >26 mmol l-1: 42%) or with a SOFA at least 2 (bicarbonate <21 mmol l-1: 8%; 21 to 26 mmol l-1: 40%; >26 mmol l-1: 37%). In-hospital mortality was 78.1% (n=89); 1-year-survival-rate was 10.5% (95% CI, 5.5 to 17.7) and survival with a good neurological outcome was 6.1% (95% CI, 2.5 to 12.2). CONCLUSION Cardiac arrest in ICU is a rare complication with a high mortality and low rate of good neurological outcome. The development of a structured approach to resuscitation should include all available resources of an ICU and adequately consider the complete diagnostic and therapeutic spectra as our results indicate that these are still underused. The development of prediction models of death should take into account cardiac and hepatic comorbidities, continuous renal replacement therapy, SOFA at least 2 before cardiac arrest and bicarbonate level. Further research should concentrate on identifying early predictors and on the prevention of cardiac arrest in ICU.

Epidemiology of intensive care unit cardiac arrest: Characteristics, comorbidities, and post-cardiac arrest organ failure - A prospective observational study. Resuscitation 2020; 156:92-98.

Abstract
BACKGROUND Critically ill patients in intensive care units can frequently suffer from cardiac arrest (ICU-CA), the incidence of ICU-CA is associated with high mortality. Most studies on ICU-CA focused on risk factors and intra-arrest determinants. However, there is a lack of data on organ failure after ICU-CA and its clinical implications for outcome. This study aimed to investigate ICU-CA incidence, outcome and the occurrence of organ failure after ICU-CA. METHODS We conducted a prospective observational study over a 1-year at 12 intensive care units of a tertiary care university hospital. We included all consecutive adult patients suffering cardiac arrest (CA) during the ICU stay. Incidence, clinical and neurological outcome, as well as organ failure and support were assessed. RESULTS Out of 7690 patients, 176 (2%) with ICU-CA were identified during the study period. Male patients comprised 63% and the median age was 70 (58-78) years. The median ICU stay before ICU-CA was 3 (1-8) days. The initial cardiac rhythm was shockable (VT/VF) in 23% of patients; defibrillation during CPR was performed in 19%. The presumed cause of CA was cardiac in 24%, and sustained ROSC was observed in 80% of patients. Before CA 57% (n = 100) of patients were sedated, 63% (n = 110) mechanically ventilated, 70% needed vasopressor therapy and renal replacement therapy was necessary in 27% (n = 48) of patients. Organ failure after ICU-CA was common, 70% suffered from post-CA cardiac failure, renal replacement therapy was newly initiated in 26% of patients and liver failure occurred in 24% of patients. Mortality at ICU-discharge and at hospital discharge was 66 % and 68 %, respectively. Multivariate regression analysis identified the SOFA score [HR 1.09, 95% CI (0.92-3.18); p < 0.05] and liver failure [HR 2.44, 95% CI (1.39-4.26); p < 0.001] after ICU-CA as independent predictors of mortality. CONCLUSION The incidence of ICU-CA is rare in critically ill patients. Organ failure before and after ICU-CA is common; liver failure incidence and severity of illness after ICU-CA are independent predictors of mortality and should be considered in further decisions on ICU therapy.

Abstract
According to the World Health Organization, the three leading causes of mortality in lower-middle-income countries (LMIC) are ischemic heart disease (IHD), stroke, and lower respiratory infections (LRIs), causing 111.8, 68.8, and 51.5 annual deaths per 100,000, respectively. Due to barriers to healthcare, patients frequently present in critical stages of these diseases. Measured implementations in critical care in LMIC have been published; however, the literature has not been formally reviewed. We performed a systematic review of the literature indexed in PubMed as of October 2017. Abstracts were limited to human studies in English, French, and Spanish, conducted in LMIC, and containing quantitative data on acute care of IHD, stroke, and LRI. The search resulted in 4994 unique abstracts. Through multiple rounds of screening using criteria determined a priori, 161 manuscripts were identified: 38 for IHD, 20 for stroke, 26 for adult LRI, and 78 for pediatric LRI. These studies, predominantly from Asia, demonstrate successful diagnostic and treatment measures used in providing acute care for patients in LMIC. Given that, only four manuscripts originated in Central or South America, original research from these areas is lacking. IHD, stroke, and LRIs are significant causes of mortality, especially in LMIC. Diagnostic and therapeutic interventions for IHD (monitoring, medications, thrombolytics, percutaneous intervention, coronary artery bypass graft), stroke (therapeutic hypothermia, medications, and thrombolytics), and LRI (oxygen saturation measurement, diagnostic ultrasound, administration of oxygen, appropriate antibiotics, and other medications) have been studied in LMIC and published.

Abstract
BACKGROUND There are few reports of the effectiveness or satisfaction with simulation to learn cardiac surgical resuscitation skills. OBJECTIVES To test the effect of simulation on the self-confidence of nurses to perform cardiac surgical resuscitation simulation and nurses' satisfaction with the simulation experience. METHODS A convenience sample of sixty nurses rated their self-confidence to perform cardiac surgical resuscitation skills before and after two simulations. Simulation performance was assessed. Subjects completed the Satisfaction with Simulation Experience scale and demographics. RESULTS Self-confidence scores to perform all cardiac surgical skills as measured by paired t-tests were significantly increased after the simulation (d=-0.50 to 1.78). Self-confidence and cardiac surgical work experience were not correlated with time to performance. Total satisfaction scores were high (mean 80.2, SD 1.06) indicating satisfaction with the simulation. There was no correlation of the satisfaction scores with cardiac surgical work experience (τ=-0.05, ns). CONCLUSION Self-confidence scores to perform cardiac surgical resuscitation procedures were higher after the simulation. Nurses were highly satisfied with the simulation experience.

Abstract
INTRODUCTION The aim of this study was to determine the association of early treatment intensity with hospital mortality of intensive care unit (ICU) patients. METHODS We performed an observational study based on a national ICU registry. We included adult patients treated in Finnish ICUs between 2003 and 2013 with the length of ICU stay of more than 3 days. We measured treatment intensity with the Therapeutic Intervention Scoring System (TISS-76). We assessed mean and daily TISS scores. To define the change in treatment intensity during the first days in the ICU, we calculated the difference between the TISS score on day 3 and the score on day 1 (ΔTISS). We used multivariate logistic regression to adjust for baseline differences and continuous net reclassification improvement (NRI) to determine the impact of adding TISS data to the baseline prediction model on its prognostic performance. RESULTS We identified 42,493 patients eligible for the study. For 71% of the patients, ΔTISS was ≤ 0 and crude hospital mortality was 18%. ΔTISS > 0 was observed for 29% of the patients, with a hospital mortality of 23%. When compared to the group ΔTISS ≤ 0, the category ΔTISS > 0 was independently associated with substantially increased mortality. Adding TISS data to the prediction model resulted in the improvement of prognostic performance particularly in the patients with the lowest initial baseline risk. CONCLUSIONS Early increase in TISS scores was associated with increased risk of death, especially in patients with a lower initial severity of illness.

Abstract
Repeat myocardial revascularization procedures are markedly different from de novo interventions, with increased procedural risk and technical-demanding complexity. However the number of patients previously treated with coronary artery bypass graft (CABG) that need a repeat revascularization due to graft failure is increasing consistently. Late graft failure, usually caused by saphenous vein grafts (SVG) attrition, is certainly not uncommon. However PCI on degenerated SVG presents higher complication rate and worse clinical outcome compared with native arteries interventions. In acute graft failure setting, PCI represents a valuable option to treat postoperative myocardial infarction.

Abstract
OBJECTIVES Perioperative myocardial infarction (MI) with ischaemia-reperfusion injury (IRI) is a devastating entity occurring in 1-2% of patients after cardiac surgery. The molecular pathway leading to myocardial cellular destruction after MI may include monoamine oxidases. We experimentally investigated whether moclobemide, a monoamine oxidase inhibitor, enhances myocardial recovery after cardiac arrest and MI. METHODS Fifty-six syngeneic Fischer rats underwent heterotopic cardiac transplantation to induce reversible IRI after cardiac arrest. Twenty-eight rats also underwent permanent ligation of the left anterior descending coronary artery to induce MI after cardiac arrest. Twenty-eight rats with or without MI were treated with subcutaneous moclobemide 10 mg/kg/day. Methods used to study myocardial recovery were microdialysis for intramyocardial metabolism, histology and quantitative reverse-transcription polymerase chain reaction for high-mobility group box-1 (HMGB1), haeme oxygenase-1 (HO-1), interleukin-6, hypoxia-inducible factor 1α and macrophages (CD68). RESULTS Pyruvate increased in MI treated with moclobemide versus IRI with moclobemide (29.19 ± 7.64 vs 13.86 ± 8.49 µM, P = 0.028), reflecting metabolic activity after cardiac arrest and reperfusion. Myocardial inflammation increased in MI compared with IRI after 1 h (0.80 ± 0.56 vs 0, point score units [PSUs], P = 0.003), but decreased after 5 days in MI treated with moclobemide versus MI alone (0.80 ± 0.83 vs 2.00 ± 0.70, PSU, P = 0.033). Expressions of HMGB1, CD68 and HO-1 decreased in MI treated with moclobemide versus MI alone (1.33 ± 0.20 vs 1.75 ± 0.24, fold changes [FCs], P = 0.028; 5.15 ± 1.10 vs 9.59 ± 2.75, FC, P = 0.050; 10.41 ± 4.17 vs 21.28 ± 10.01, FC, P = 0.047), indicating myocardial recovery and increased cellularity of remote intramyocardial arteries. CONCLUSIONS Moclobemide enhances myocardial recovery after cardiac arrest and MI; inhibition of remote myocardial changes may be achieved by targeting treatment against monoamine oxidase.

Temporal trends in cardiac arrest incidence and outcome in Finnish intensive care units from 2003 to 2013. Intensive Care Med 2014; 40:1853-61.

Abstract
PURPOSE To estimate temporal trends in incidence and hospital mortality after cardiac arrest in Finnish intensive care units. METHODS Using a large nationwide intensive care unit (ICU) database we identified patients suffering from cardiac arrest following ICU admission (ICU-CA) during the study period (2003-2013). ICU-CA was defined as need for cardiopulmonary resuscitation and/or defibrillation (non-arrest cardioversions were excluded) according to the Therapeutic Intervention Scoring System-76. Patients admitted with an admission diagnosis of cardiac arrest were excluded. We determined crude incidence and risk-adjusted hospital mortality (based on a customized severity of illness model) for all ICU-CA patients, and for predefined admission diagnosis subgroups. Temporal trends for the observed period were calculated for crude incidence and risk-adjusted hospital mortality. RESULTS Crude incidence for all ICU-CA patients was 29/1,000 ICU admissions, with the highest incidence 118/1,000 in the non-operative cardiovascular subgroup. Overall hospital mortality for ICU-CA patients was 55.5% [95% confidence interval (CI) 54-57%]. Hospital mortality was 53.1% (95% CI 50.4-55.8%) for non-operative cardiovascular ICU-CA patients, 32.9% (95% CI 26.9-38.9%) for post cardiac surgery ICU-CA patients, and 56.3% (95% CI 51.2-61.3%) for neurological/neurosurgical ICU-CA patients. There was a significant reduction in the overall ICU-CA incidence and in the risk-adjusted hospital mortality of ICU-CA and non-cardiac arrest cases (non-CA) over the observed study period (p < 0.001). CONCLUSION Our data suggest that the incidence of ICU-CA has decreased in Finnish ICUs between 2003 and 2013. Similar reduction in hospital mortality over time was observed for both ICU-CA and non-CA populations.

SOURCES AND METHODS We conducted a literature search of the PubMed, CINAHL and Cochrane databases with the following search terms (medical subheadings): heart arrest AND intensive care unit OR critical care OR critical care nursing OR monitored bed OR monitored ward OR monitored patient. We included articles published from the 1st of January 1990 till 31st of December 2012. After exclusion of all duplicates and irrelevant articles we evaluated quality of studies using a predefined quality assessment score and summarized outcome data. RESULTS The initial search yielded 794 articles of which 780 were excluded. Three papers were added after a manual search of the eligible studies' references. One paper was identified manually from the literature published after our initial search was completed, thus the final sample consisted of 18 papers. Of the studies included thirteen were retrospective, two based on prospective registries and three were focused prospective studies. All except two studies were from a single institution. Six studies reported the incidence of intensive care unit cardiac arrest, which varied from 5.6 to 78.1 cardiac arrests per 1000 intensive care unit admissions. The most frequently reported initial cardiac arrest rhythms were non-shockable. Patient outcome was variable with survival to hospital discharge being in the range of 0-79% and long-term survival ranging from 1 to 69%. Nine studies reported neurological status of survivors, which was mostly favorable, either no neurological sequelae or cerebral performance score mostly of 1-2. Studies focusing on post cardiac surgery patients reported the best long-term survival rates of 45-69%. CONCLUSIONS At present data on intensive care unit cardiac arrest is quite limited and originates mostly from retrospective single center studies. The quality of data overall seems to be poor and thus focused prospective multi-center studies are needed.

Abstract
OBJECTIVE Follow-up studies of patients surviving emergency resternotomy, open cardiac massage, and additional emergency cardiac surgery following coronary artery bypass grafting (CABG) remain sparse and studies focusing on health-related quality of life are lacking. Our aim was to elucidate the long-term course of patients experiencing this hazardous complication. METHODS Between 1988 and 1999, 76 patients suffered sudden hemodynamic collapse following isolated CABG. All patients underwent emergency resternotomy and open cardiac massage. An emergency cardiac reoperation was performed in the 62 (82%) primary survivors. Additional 76 patients were pair-matched to the study patients on the basis of their preoperative characteristics and served as controls. Of the study patients, 41 (54%), and of the controls, 76, (100%) were discharged. In December 2009, all patients were traced with respect to mortality data and the health-related quality of life of living patients was studied using the RAND-36 Item Health Survey questionnaire. RESULTS Altogether 19 (73%) of the 26 study patients, and 38 (84%) of the 45 controls were available. After exclusion of the early deaths, the life expectancy was similar between the groups: neither overall (p = 0.60) nor cardiac (p = 0.64) survival differed significantly after a mean follow-up time of 15.1 ± 3.5 years. In addition, cardiac re-interventions were equally frequently required in both the groups. The RAND-36 scores were congruent (p = ns) between the groups and the age- and sex-matched national reference population in the health-related quality-of-life dimensions describing physical, mental, and social domains. CONCLUSIONS Patients who have survived severe hemodynamic collapse, open cardiac massage, and emergency cardiac reoperation following CABG achieve similar long-term prognosis in terms of survival and cardiac interventions as the pair-matched control patients. In addition, 15 years postoperatively, they have a good health-related quality of life, similar to that of an age- and sex-matched national reference population.
