RESUMO

BACKGROUND: In adults, the most common cause of out-of-hospital cardiac arrests (OHCA) is acute coronary artery occlusion. If an immediate coronary angiogram (CAG) is recommended for survivors presenting a ST segment elevation on the electrocardiogram (ECG) performed after resuscitation, there is still a debate regarding the best strategy in patients without ST segment elevation. HYPOTHESIS: Performing an immediate CAG after an OHCA without ST segment elevation on the post-resuscitation ECG and no obvious non-cardiac cause of arrest could lead to a better 180-day survival rate with no or minimal neurological sequel as compared with a delayed CAG performed 48 to 96 hours after the arrest. DESIGN: The EMERGE trial is a prospective national, randomized, open and parallel group trial, in which 970 survivors of OHCA will be randomized (1:1) to either immediate (as soon as possible after return of spontaneous circulation) or delayed (48 to 96 h) CAG. Participants will be OHCA patients with no ST segment elevation on the post resuscitation ECG and no obvious non-cardiac cause of arrest. The primary endpoint of the study is the 180-day survival rate with no or minimal neurological sequel corresponding to Cerebral Performance Category (CPC) 1 or 2. The secondary endpoints are: occurrence of shock during the first 48 hours, ventricular tachycardia and/or fibrillation during the first 48 hours, change in left ventricular ejection fraction between baseline and 180 days assessed by echocardiogram, neurological status evaluated by the CPC score at intensive care unit (ICU) discharge and day 90 neurological status assessed by the Glasgow Outcome Scale Extended score (GOSE) at 90 and 180 days, overall survival rate, and hospital length of stay. SUMMARY: The EMERGE trial is a prospective, multicenter, randomized, controlled trial that will assess the 180-day survival rate with no or minimal neurologic sequel in patients resuscitated from an OHCA without ST segment elevation and who will be managed with either immediate or delayed CAG.

RESUMO

OBJECTIVE: While cardiac arrest (CA) patients discharged alive from intensive care unit (ICU) are considered to have good one-year survival but potential neurological impairment, comparisons with other ICU sub-populations non-admitted for CA purpose are still lacking. This study aimed to compare long-term outcome and health-related quality of life (HRQOL) between CA patients and patients admitted to ICU for all other causes. METHODS: In 1635 patients discharged alive from 21 European ICUs in an ancillary analysis of a prospective multicentric cohort, we compared CA causes of ICU admission to all other causes of ICU admissions (named non-CAs). The primary endpoint was one-year survival rate after ICU discharge. Secondary endpoints included HRQOL at 3, 6 and 12 months after ICU discharge using the outcome survey short form-36 (SF36). Propensity score matching was used to consider the probability of having CA. RESULTS: Of the 1635 patients, 1561 were included in this study comprised of 1447 non-CAs and 114 CAs. At one-year in the non-matched population, survival rate was greater in the CA group 89% versus the non-CA group 78% (log rank p = 0.0056). In the matched population, this difference persisted between CAs and non-CAs (log rank p = 0.049). The physical component summary of the SF36 scale was higher in the CA group than in the non-CA group at all time points in both non-matched and matched populations. CONCLUSIONS: CA patients discharged alive from ICU have a better one-year survival and a better HRQOL specifically on physical functions than patients admitted to ICU for other causes.

RESUMO

AIM: Coronary artery disease (CAD) has recently been emphasized as a major cause of sudden cardiac arrest (SCA) in young adults. We aim to assess the rate of immediate coronary angiography performance in young patients resuscitated from SCA. METHODS: From May 2011 to May 2017, all cases of out-of-hospital SCA aged 18-40 years alive at hospital admission were prospectively included in 48 hospitals of the Great Paris area. Cardiovascular causes of SCA were centrally adjudicated, and management including immediate coronary angiography performance was assessed. RESULTS: Out of 3579 SCA admitted alive, 409 (11.4%) patients were under 40 years of age (32.3 ± 6.2 years, 69.7% males), with 244 patients having a definite cause identified. Among those, CAD accounted for 72 (29.5%) cases, of which 64 (88.9%) were acute coronary syndromes. The rate of immediate coronary angiography was only 41.7% compared to 65.1% among those ≥40-years (P < 0.001). During the study period, while the rate of immediate coronary angiography increased from 60.5% to 70.3% (P < 0.001) in patients aged ≥40 years, the rate in patients aged less than 40 years remained stable (43.5% to 45.3%, P = 0.795). Patients younger than 40 years were significantly less likely to undergo immediate coronary angiography (OR = 0.34, 95% CI: 0.25-0.47), although early angiography was associated with survival at hospital discharge (OR = 2.68, 95% CI: 1.21-6.00). CONCLUSION: CAD is the first cause of SCA in young adults aged less than 40 years. The observed low rates of immediate coronary angiography suggest a missed opportunity for early intervention.

RESUMO

PURPOSE: Recent doubts regarding the efficacy may have resulted in a loss of interest for targeted temperature management (TTM) in comatose cardiac arrest (CA) patients, with uncertain consequences on outcome. We aimed to identify a change in TTM use and to assess the relationship between this change and neurological outcome. METHODS: We used Utstein data prospectively collected in the Sudden Death Expertise Center (SDEC) registry (capturing CA data from all secondary and tertiary hospitals located in the Great Paris area, France) between May 2011 and December 2017. All cases of non-traumatic OHCA patients with stable return of spontaneous circulation (ROSC) were included. After adjustment for potential confounders, we assessed the relationship between changes over time in the use of TTM and neurological recovery at discharge using the Cerebral Performance Categories (CPC) scale. RESULTS: Between May 2011 and December 2017, 3925 patients were retained in the analysis, of whom 1847 (47%) received TTM. The rate of good neurological outcome at discharge (CPC 1 or 2) was higher in TTM patients as compared with no TTM (33% vs 15%, P < 0.001). Gender, age, and location of CA did not change over the years. Bystander CPR increased from 55% in 2011 to 73% in 2017 (P < 0.001) and patients with a no-flow time longer than 3 min decreased from 53 to 38% (P < 0.001). The use of TTM decreased from 55% in 2011 to 37% in 2017 (P < 0.001). Meanwhile, the rate of patients with good neurological recovery remained stable (19 to 23%, P = 0.76). After adjustment, year of CA occurrence was not associated with outcome. CONCLUSIONS: We report a progressive decrease in the use of TTM in post-cardiac arrest patients over the recent years. During this period, neurological outcome remained stable, despite an increase in bystander-initiated resuscitation and a decrease in "no flow" duration.

RESUMO

AIMS: Out-of-hospital cardiac arrest (OHCA) without return of spontaneous circulation (ROSC) despite conventional resuscitation is common and has poor outcomes. Adding extracorporeal membrane oxygenation (ECMO) to cardiopulmonary resuscitation (extracorporeal-CPR) is increasingly used in an attempt to improve outcomes. METHODS AND RESULTS: We analysed a prospective registry of 13 191 OHCAs in the Paris region from May 2011 to January 2018. We compared survival at hospital discharge with and without extracorporeal-CPR and identified factors associated with survival in patients given extracorporeal-CPR. Survival was 8% in 525 patients given extracorporeal-CPR and 9% in 12 666 patients given conventional-CPR (P = 0.91). By adjusted multivariate analysis, extracorporeal-CPR was not associated with hospital survival [odds ratio (OR), 1.3; 95% confidence interval (95% CI), 0.8-2.1; P = 0.24]. By conditional logistic regression with matching on a propensity score (including age, sex, occurrence at home, bystander CPR, initial rhythm, collapse-to-CPR time, duration of resuscitation, and ROSC), similar results were found (OR, 0.8; 95% CI, 0.5-1.3; P = 0.41). In the extracorporeal-CPR group, factors associated with hospital survival were initial shockable rhythm (OR, 3.9; 95% CI, 1.5-10.3; P = 0.005), transient ROSC before ECMO (OR, 2.3; 95% CI, 1.1-4.7; P = 0.03), and prehospital ECMO implantation (OR, 2.9; 95% CI, 1.5-5.9; P = 0.002). CONCLUSIONS: In a population-based registry, 4% of OHCAs were treated with extracorporeal-CPR, which was not associated with increased hospital survival. Early ECMO implantation may improve outcomes. The initial rhythm and ROSC may help select patients for extracorporeal-CPR.

RESUMO

BACKGROUND: Patients who are treated with targeted temperature management after out-of-hospital cardiac arrest with shockable rhythm are at increased risk for ventilator-associated pneumonia. The benefit of preventive short-term antibiotic therapy has not been shown. METHODS: We conducted a multicenter, double-blind, randomized, placebo-controlled trial involving adult patients (>18 years of age) in intensive care units (ICUs) who were being mechanically ventilated after out-of-hospital cardiac arrest related to initial shockable rhythm and treated with targeted temperature management at 32 to 34°C. Patients with ongoing antibiotic therapy, chronic colonization with multidrug-resistant bacteria, or moribund status were excluded. Either intravenous amoxicillin-clavulanate (at doses of 1 g and 200 mg, respectively) or placebo was administered three times a day for 2 days, starting less than 6 hours after the cardiac arrest. The primary outcome was early ventilator-associated pneumonia (during the first 7 days of hospitalization). An independent adjudication committee determined diagnoses of ventilator-associated pneumonia. RESULTS: A total of 198 patients underwent randomization, and 194 were included in the analysis. After adjudication, 60 cases of ventilator-associated pneumonia were confirmed, including 51 of early ventilator-associated pneumonia. The incidence of early ventilator-associated pneumonia was lower with antibiotic prophylaxis than with placebo (19 patients [19%] vs. 32 [34%]; hazard ratio, 0.53; 95% confidence interval, 0.31 to 0.92; P = 0.03). No significant differences between the antibiotic group and the control group were observed with respect to the incidence of late ventilator-associated pneumonia (4% and 5%, respectively), the number of ventilator-free days (21 days and 19 days), ICU length of stay (5 days and 8 days if patients were discharged and 7 days and 7 days if patients had died), and mortality at day 28 (41% and 37%). At day 7, no increase in resistant bacteria was identified. Serious adverse events did not differ significantly between the two groups. CONCLUSIONS: A 2-day course of antibiotic therapy with amoxicillin-clavulanate in patients receiving a 32-to-34°C targeted temperature management strategy after out-of-hospital cardiac arrest with initial shockable rhythm resulted in a lower incidence of early ventilator-associated pneumonia than placebo. No significant between-group differences were observed for other key clinical variables, such as ventilator-free days and mortality at day 28.

RESUMO

BACKGROUND: Platelet transfusion is aimed at increasing platelet counts to prevent or treat bleeding. Critically ill cancer patients with hypoproliferative thrombocytopenia are high consumers of blood products. We herein described their post-transfusion platelet responses in the intensive care unit (ICU) and analyzed the determinants of poor post-transfusion increments. STUDY DESIGN AND METHODS: This was a single-center 9-year (2009-2017) retrospective observational study. Patients with malignancies and presumed or proven hypoproliferative thrombocytopenia who had received at least one platelet transfusion in the ICU were included. Poor post-transfusion platelet increments were defined as body surface-adjusted corrected count increment (CCI) <7, or alternatively as weight-adjusted platelet transfusion recovery (PTR) <0.2. Patients were deemed refractory to platelet transfusions when two consecutive ABO-compatible transfusions resulted in poor platelet increments. RESULTS: A total of 1470 platelet transfusions received by 326 patients were analyzed. Indications for platelet transfusions were distributed into prophylactic (44.5%), peri-procedural (18.1%) and therapeutic (37.4%). Regardless of indications, 54.6% and 55.4% of transfusion episodes were associated with a CCI <7 or a PTR <0.2. Factors independently associated with poor post-transfusion increments were lower body mass index, spleen enlargement, concurrent severity of clinical condition, fever ≥39°C, antibiotic therapy and increased storage duration of platelet concentrates. Eventually, 48 patients developed refractoriness to platelet transfusion, which was associated increased incidence of bleeding events. CONCLUSION: Platelet transfusions are often associated with poor increments in critically ill cancer patients with hypoproliferative thrombocytopenia. The findings suggest amenable interventions to improve the platelet transfusion practices in this setting.

RESUMO

BACKGROUND: Data is scarce on hemorrhagic and thrombotic complications in patients with ST-elevation myocardial infarction (STEMI) associated with out-of-hospital cardiac arrest (OHCA). METHODS: This is a monocentric, retrospective study conducted from January 2012 to December 2017 in a tertiary university hospital, which serves as a cardiac arrest center for a large urban area. Over the study period, all consecutive patients who were treated with stent implantation for STEMI with or without OHCA were included. Baseline characteristics, treatments, hemorrhagic and thrombotic events were compared between STEMI patients with and without OHCA. Univariate and multivariate analysis were performed in order to identify predictors of 30-day mortality, occurrence of major bleeding (MB), and early stent thrombosis (ST). RESULTS: A total of 549 patients treated for STEMI without OHCA and 146 patients for STEMI with OHCA were included. The incidence of definite ST and MB after coronary angioplasty was significantly higher in patients with OHCA (2.6% vs. 7.5%, p = 0.004 and 3.3% vs. 19.2%, p < 0.001, respectively). Independent predictors of MB in OHCA patients were anticoagulation therapy (HR = 3.11, 95%CI [1.22-7.98], p = 0.02) and the use of glycoprotein IIb/IIIa inhibitors (HR = 4.16, 95%CI [1.61-10.79], p = 0.003). Independent predictors of mortality in OHCA patients were age (HR = 1.05, 95%CI [1.02-1.09], p = 0.004) and ST (HR = 5.62, 95%CI [1.61-19.65], p = 0.007, with a protective effect of new anti-P2Y12 treatments (HR = 0.20, 95%CI [0.08-0.46], p < 0.001). CONCLUSION: Patients treated for STEMI associated with OHCA are at higher-risk of ST and MB than those who did not experience cardiac arrest. In this subset of patients, prospective studies are needed to better evaluate the balance of thrombosis and hemorrhage.

RESUMO

BACKGROUND: Moderate therapeutic hypothermia is currently recommended to improve neurologic outcomes in adults with persistent coma after resuscitated out-of-hospital cardiac arrest. However, the effectiveness of moderate therapeutic hypothermia in patients with nonshockable rhythms (asystole or pulseless electrical activity) is debated. METHODS: We performed an open-label, randomized, controlled trial comparing moderate therapeutic hypothermia (33°C during the first 24 hours) with targeted normothermia (37°C) in patients with coma who had been admitted to the intensive care unit (ICU) after resuscitation from cardiac arrest with nonshockable rhythm. The primary outcome was survival with a favorable neurologic outcome, assessed on day 90 after randomization with the use of the Cerebral Performance Category (CPC) scale (which ranges from 1 to 5, with higher scores indicating greater disability). We defined a favorable neurologic outcome as a CPC score of 1 or 2. Outcome assessment was blinded. Mortality and safety were also assessed. RESULTS: From January 2014 through January 2018, a total of 584 patients from 25 ICUs underwent randomization, and 581 were included in the analysis (3 patients withdrew consent). On day 90, a total of 29 of 284 patients (10.2%) in the hypothermia group were alive with a CPC score of 1 or 2, as compared with 17 of 297 (5.7%) in the normothermia group (difference, 4.5 percentage points; 95% confidence interval [CI], 0.1 to 8.9; P = 0.04). Mortality at 90 days did not differ significantly between the hypothermia group and the normothermia group (81.3% and 83.2%, respectively; difference, -1.9 percentage points; 95% CI, -8.0 to 4.3). The incidence of prespecified adverse events did not differ significantly between groups. CONCLUSIONS: Among patients with coma who had been resuscitated from cardiac arrest with nonshockable rhythm, moderate therapeutic hypothermia at 33°C for 24 hours led to a higher percentage of patients who survived with a favorable neurologic outcome at day 90 than was observed with targeted normothermia.

RESUMO

OBJECTIVES: The association between outcome and kidney injury detected at discharge from the ICU using different biomarkers remains unknown. The objective was to evaluate the association between 1-year survival and kidney injury at ICU discharge. DESIGN: Ancillary investigation of a prospective observational study. SETTING: Twenty-one ICUs with 1-year follow-up. PATIENTS: Critically ill patients receiving mechanical ventilation and/or hemodynamic support for at least 24 hours were included. INTERVENTIONS: Serum creatinine, plasma Cystatin C, plasma neutrophil gelatinase-associated lipocalin, urinary neutrophil gelatinase-associated lipocalin, plasma Proenkephalin A 119-159, and estimated glomerular filtration rate (on serum creatinine and plasma Cystatin C) were measured at ICU discharge among ICU survivors. MEASUREMENTS AND MAIN RESULTS: The association between kidney biomarkers at discharge and mortality was estimated using logistic model with and without adjustment for prognostic factors previously identified in this cohort. Subgroup analyses were performed in patients with discharge serum creatinine less than 1.5-fold baseline at ICU discharge. Among 1,207 ICU survivors included, 231 died during the year following ICU discharge (19.2%). Estimated glomerular filtration rate was significantly lower and kidney injury biomarkers higher at discharge in nonsurvivors. The association between biomarker levels or estimated glomerular filtration rate and mortality remained after adjustment to potential cofounding factors influencing outcome. In patients with low serum creatinine at ICU discharge, 25-47% of patients were classified as subclinical kidney injury depending on the biomarker. The association between kidney biomarkers and mortality remained and mortality was higher than patients without subclinical kidney injury. The majority of patients who developed acute kidney injury during ICU stay had elevated biomarkers of kidney injury at discharge even with apparent recovery based on serum creatinine (i.e., subclinical acute kidney disease). CONCLUSIONS: Elevated kidney biomarkers measured at ICU discharge are associated with poor 1-year outcome, including in patients with low serum creatinine at ICU discharge.

RESUMO

BACKGROUND: Less than 500 participants have been included in randomized trials comparing hypothermia with regular care for out-of-hospital cardiac arrest patients, and many of these trials were small and at a high risk of bias. Consequently, the accrued data on this potentially beneficial intervention resembles that of a drug following small phase II trials. A large confirmatory trial is therefore warranted. METHODS: The TTM2-trial is an international, multicenter, parallel group, investigator-initiated, randomized, superiority trial in which a target temperature of 33°C after cardiac arrest will be compared with a strategy to maintain normothermia and early treatment of fever (≥37.8°C). Participants will be randomized within 3 hours of return of spontaneous circulation with the intervention period lasting 40 hours in both groups. Sedation will be mandatory for all patients throughout the intervention period. The clinical team involved with direct patient care will not be blinded to allocation group due to the inherent difficulty in blinding the intervention. Prognosticators, outcome-assessors, the steering group, the trial coordinating team, and trial statistician will be blinded. The primary outcome will be all-cause mortality at 180 days after randomization. We estimate a 55% mortality in the control group. To detect an absolute risk reduction of 7.5% with an alpha of 0.05 and 90% power, 1900 participants will be enrolled. The main secondary neurological outcome will be poor functional outcome (modified Rankin Scale 4-6) at 180 days after arrest. DISCUSSION: The TTM2-trial will compare hypothermia to 33°C with normothermia and early treatment of fever (≥37.8°C) after out-of-hospital cardiac arrest.

RESUMO

BACKGROUND: Total liquid ventilation (TLV) of the lungs could provide radically new benefits in critically ill patients requiring lung lavage or ultra-fast cooling after cardiac arrest. It consists in an initial filling of the lungs with perfluorocarbons and subsequent tidal ventilation using a dedicated liquid ventilator. Here, we propose a new paradigm for a lung-conservative TLV using pulmonary volumes of perfluorocarbons below functional residual capacity (FRC). METHODS AND FINDINGS: Using a dedicated technology, we showed that perfluorocarbon end-expiratory volumes could be maintained below expected FRC and lead to better respiratory recovery, preserved lung structure and accelerated evaporation of liquid residues as compared to complete lung filling in piglets. Such TLV below FRC prevented volutrauma through preservation of alveolar recruitment reserve. When used with temperature-controlled perfluorocarbons, this lung-conservative approach provided neuroprotective ultra-fast cooling in a model of hypoxic-ischemic encephalopathy. The scale-up and automating of the technology confirmed that incomplete initial lung filling during TLV was beneficial in human adult-sized pigs, despite larger size and maturity of the lungs. Our results were confirmed in aged non-human primates, confirming the safety of this lung-conservative approach. INTERPRETATION: This study demonstrated that TLV with an accurate control of perfluorocarbon volume below FRC could provide the full potential of TLV in an innovative and safe manner. This constitutes a new paradigm through the tidal liquid ventilation of incompletely filled lungs, which strongly differs from the previously known TLV approach, opening promising perspectives for a safer clinical translation.

RESUMO

BACKGROUND: Although targeted temperature management (TTM) is recommended in comatose survivors after cardiac arrest (CA), the optimal method to deliver TTM remains unknown. We performed a meta-analysis to evaluate the effects of different TTM methods on survival and neurological outcome after adult CA. METHODS: We searched on the MEDLINE/PubMed database until 22 February 2019 for comparative studies that evaluated at least two different TTM methods in CA patients. Data were extracted independently by two authors. We used the Newcastle-Ottawa Scale and a modified Cochrane ROB tools for assessing the risk of bias of each study. The primary outcome was the occurrence of unfavorable neurological outcome (UO); secondary outcomes included overall mortality. RESULTS: Our search identified 6886 studies; 22 studies (n = 8027 patients) were included in the final analysis. When compared to surface cooling, core methods showed a lower probability of UO (OR 0.85 [95% CIs 0.75-0.96]; p = 0.008) but not mortality (OR 0.88 [95% CIs 0.62-1.25]; p = 0.21). No significant heterogeneity was observed among studies. However, these effects were observed in the analyses of non-RCTs. A significant lower probability of both UO and mortality were observed when invasive TTM methods were compared to non-invasive TTM methods and when temperature feedback devices (TFD) were compared to non-TFD methods. These results were significant particularly in non-RCTs. CONCLUSIONS: Although existing literature is mostly based on retrospective or prospective studies, specific TTM methods (i.e., core, invasive, and with TFD) were associated with a lower probability of poor neurological outcome when compared to other methods in adult CA survivors (CRD42019111021).

RESUMO

BACKGROUNDS: In survivors of out-of-hospital cardiac arrest (OHCA), acute kidney injury (AKI) is frequent and is associated with numerous factors of definitive renal injury. We made the hypothesis that AKI after OHCA was a strong risk factor of long-term chronic kidney disease (CKD). We aimed to evaluate long-term renal outcome of OHCA survivors according the occurrence of AKI in ICU. METHODS: We used prospectively collected data from consecutive OHCA patients admitted between 2007 and 2012 in a tertiary medical ICU. AKI was defined by the Kidney Disease Improving Global Outcomes (KDIGO) criteria. Long-term creatinine level was the last blood creatinine assessment we were able to retrieve. The main outcome was the occurrence of CKD, defined by an estimated glomerular filtration rate (eGFR) lower than 60 mL/min/1.73m2 according to the MDRD equation. Long-term mortality was evaluated as well. Factors associated with CKD occurrence were evaluated by competing risk survival analysis (Fine Gray and Cox cause specific models). RESULTS: Among the 246 OHCA patients who were discharged alive, outcome of 133 patients was available (median age 55 [iqr 46, 68], 75.2% of male). During a median follow-up time of 1.8 [0.8-2.5] years, CKD occurred in 17 (12.7%) patients and 24 (18%) patients died. A previous history of arterial hypertension (sHR = 3.28[1.15;9.39], p = 0.027; CSH = 4.83 [1.57;14.9], p = 0.006), AKI during ICU stay (sHR = 3.72[1.40;9.84], p = 0.008; CSH = 5.41[1.79;16.3], p = 0.003) and an age higher than 55 (sHR = 6.13[1.55;24.3], p = 0.009; CSH = 2.16[1.72;43.8], p = 0.006) were independently associated with CKD occurrence. AKI was not associated with long-term mortality (sHR = 0.73 [0.27;1.99], p = 0.55; CSH = 0.75 [0.28;2.01], p = 0.57). CONCLUSION: In OHCA survivors, CKD was a frequent long-term complication. AKI during ICU stay was a strong determinant of long-term CKD occurrence.

RESUMO

OBJECTIVES: A higher survival rate was observed in Sudden Cardiac Arrest (SCA) occurring during sports activities, although the underlying mechanisms remain unclear. We tested the hypothesis that better initial management, rather than sports per se, may account for the observed better outcomes during sports activities. METHODS: Data was taken between May 2011 and March 2016 from a prospective ongoing registry that includes all SCA in Paris and suburbs (6.7 million inhabitants). Sports-related SCA (i.e. SCA occurring during sport activities or within one hour of cessation of the activity) were identified. RESULTS: Over the study period, 13,400 SCA occurred, of which 154 were sports-related (median age: 51.2 years, 96.1% males). At discharge, sports activity was associated with an 8-times higher survival rate (39.7% vs. 5.1%, P < 0.001). Logistic regression showed that after considering potential confounders, including age, gender, SCA location, witness presence, time to response, and initial shockable rhythm, occurrence of SCA during sports was associated with a higher survival rate (OR 1.77, 95% CI 1.14-2.74, P = 0.01). However, after further adjustment for initial basic life support, i.e. bystander CPR and AED use, there was no association between sports setting and survival at hospital discharge (OR 1.43, 95% CI 0.91-2.23, P = 0.12). CONCLUSION: Sports-related SCA is a rare event, with an 8-times higher survival rate compared to non-sports-related SCA. Better initial management, including bystander CPR and AED use, rather than sports per se, mainly accounts this difference. This highlights the major importance of population education to basic life support in improving SCA outcome.
