Abstract Background Cardiogenic shock (CS) is often associated with severe heart rhythm disturbances (SHRD). Percutaneous left ventricular assist devices (pLVAD) can actively unload the left ventricle (LV) using a micro-axial pump and resulting in a decreased end-diastolic pressure and wall tension. These parameters are suspected to induce and maintain rhythmological instability. Purpose In the current study, we firstly describe the termination of SHRD immediately (less than 5 minutes) after LV-unloading in CS patients with previous unsuccessful antiarrhythmic treatment. Methods The Dresden Impella Registry is an ongoing single center registry. Since 2014, a total of 97 patients were included. Each of whom had received a micro-axial heart pump in refractory CS supplying a circulatory support of 3.5 l/min. We investigated the subgroup of patients which initially exhibited SHRD like ventricular tachycardia or ventricular fibrillation, and showed an immediately stabilization of heart rhythm directly after insertion of pLVAD (HRS). This subgroup was compared with the other patients of the registry (NHRS). Therefore, clinical laboratory and hemodynamic parameters were measured and analyzed. Results In 19 patients of the registry a HRS was observed. Among these patients, a CPR before pLVAD was performed in 89.5% with a mean duration of 30.7min, whereby 52.6% sustained an in-hospital cardiac arrest and 36.9% an out-of-hospital cardiac arrest respectively. In the NHRS subgroup (n=78), a CPR was performed less frequently (39.7%; p<0.001) with shorter mean duration (19.5min; p=0.016) and a lower out-of-hospital ratio (12.8%; p=0.014). The comparison of hemodynamic parameters between the HRS and NHRS cohort showed no difference in mean arterial pressure, heart rate, left ventricular ejection fraction (LVEF), and serum lactate. The mortality showed no differences between the HRS and NHRS cohort at 30 days (68.4% vs. 58.1%; p=0.413) and 90 days (78.9% vs. 66.7%; p=0.306), despite a more frequent and longer CPR with a higher ratio of out-of-hospital cardiac arrests among the HRS patients. There was also no difference in mortality between patients, who received an in-hospital CPR. However, HRS patients with in-hospital CPR showed a significantly lower serum lactate and NA dosage compared to the NHRS cohort (Figure A & B). Furthermore, NA recovery, defined as 50% decrease as compared to the initial NA dosage, occurred more frequently in the HRS group (HRS 42.9% vs. NHRS 7.1%; p=0.049). The LVEF nearly double in the HRS subgroup after LV-unloading, whereas it did not change in the NHRS subgroup (relative LVEF increase: HRS 95% vs. NHRS 15%). Figure A & B Conclusion The termination of SHRD due to LV-unloading occurred in around 20% of CS patients in Dresden Impella Registry and was associated with a lower serum lactate and NA dosage as well as an improved LVEF among patients with in-hospital CPR.

Pheochromocytoma should be considered in young patients who have acute cardiac decompensation, even if they have no history of hypertension. Atrioventricular node ablation and pacemaker placement should be considered for stabilizing pheochromocytoma patients with cardiogenic shock due to atrial tachyarrhythmias. A 38-year-old black woman presented with cardiogenic shock (left ventricular ejection fraction, &lt;0.15) that did not respond to the placement of an intra-aortic balloon pump. A TandemHeart® Percutaneous Ventricular Assist Device was inserted emergently. After atrioventricular node ablation and placement of a temporary pacemaker, the TandemHeart was removed. Computed tomography of the abdomen revealed a pheochromocytoma. After placement of a permanent pacemaker, the patient underwent a right adrenalectomy. This is, to our knowledge, the first reported case of pheochromocytoma-induced atrial tachyarrhythmia that led to cardiogenic shock and cardiac arrest unresolved by the placement of 2 different ventricular assist devices, but that was completely reversed by radiofrequency ablation of the atrioventricular node and the placement of a temporary pacemaker. We present the patient's clinical, laboratory, and imaging findings, and we review the relevant literature.

Abstract Timely and effective antithrombotic therapy is critical to improving outcome, including survival, in patients with acute coronary syndrome (ACS). Achieving effective platelet inhibition and anticoagulation, with minimal risk, is particularly important in high-risk ACS patients, especially those with cardiogenic shock (CS) or those successfully resuscitated following out-of-hospital cardiac arrest (OHCA), who have a 30-50% risk of death or a recurrent ischaemic event over the subsequent 30 days. There are unique challenges to achieving effective and safe antithrombotic treatment in this cohort of patients that are not encountered in most other ACS patients. This position paper focuses on patients presenting with CS or immediately post-OHCA, of presumed ischaemic aetiology, and examines issues related to thrombosis and bleeding risk. Both the physical and pharmacological impacts of CS, namely impaired drug absorption, metabolism, altered distribution and/or excretion, associated multiorgan failure, co-morbidities and co-administered treatments such as opiates, targeted temperature management, renal replacement therapy and circulatory or left ventricular assist devices, can have major impact on the effectiveness and safety of antithrombotic drugs. Careful attention to the choice of antithrombotic agent(s), route of administration, drug-drug interactions, therapeutic drug monitoring and factors that affect drug efficacy and safety, may reduce the risk of sub- or supra-therapeutic dosing and associated adverse events. This paper provides expert opinion, based on best available evidence, and consensus statements on optimising antithrombotic therapy in these very high-risk patients, in whom minimising the risk of thrombosis and bleeding is critical to improving outcome.

BackgroundST-segment elevation myocardial infarction (STEMI) outcomes are influenced by the location of the culprit vessel with worse outcomes portended with a left anterior descending (LAD) culprit lesion. However, relatively little is known about the independent association of LAD involvement with clinical outcomes of patients with STEMI with and without out-of-hospital cardiac arrest (OHCA).MethodsWe identified 91 patients with and 929 without a preceding OHCA within the Vancouver Coastal Health Authority who presented with an acute STEMI and underwent primary percutaneous coronary intervention between 26 June 2007 and 31 March 2016.ResultsPatients with STEMI with OHCA had higher rates of in-hospital cardiac arrest (43.3% vs 8.3%, p<0.001), heart failure (50.5% vs 11.3%, p<0.001), cardiogenic shock (49.5% vs 5.7%, p<0.001), mortality (35.2% vs 3.3%, p<0.001) and reduced left ventricular ejection fraction (LVEF; 42.9% vs 47.3%, p<0.001) compared with those without OHCA. Among patients without OHCA, LAD involvement was associated with increased heart failure (18.1% vs 5.2%, p<0.001), in-hospital cardiac arrest (10.7% vs 6.2%, p<0.014), cardiogenic shock (8.4% vs 3.3%, p<0.001), reduced LVEF (43.0% vs 51.2%, p<0.001) and mortality (5.2% vs 1.3%, p=0.003) compared with patients without LAD involvement. With the exception of LVEF, these associations were not seen among patients with STEMI with OHCA and an LAD culprit. The presence of an LAD culprit was not independently associated with increased hospital mortality among patients with OHCA after adjusting for potential confounding factors.ConclusionOur study has demonstrated a differential impact of LAD involvement on clinical outcomes among patients with STEMI who present with and without OHCA. Our data highlight the complexity surrounding the prognostication following OHCA complicating STEMI and demonstrate that other mechanisms other than LAD involvement contribute to the high mortality associated with OHCA as a result of STEMI.

Abstract Background Transthoracic echocardiographic (TTE) indices of myocardial function among survivors of out-of-hospital cardiac arrest (OHCA) have been related to neurological outcome; however, results are inconsistent. We hypothesized that changes in average peak systolic mitral annular velocity (s’) from 24 h (h) to 72 h following start of targeted temperature management (TTM) predict six-month neurological outcome in comatose OHCA survivors. Methods We investigated the association between peak systolic velocity of the mitral plane (s’) and six-month neurological outcome in a population of 99 patients from a randomised controlled trial comparing TTM at 33 ± 1 °C for 24 h (h) (n = 47) vs. 48 h (n = 52) following OHCA (TTH48-trial). TTE was conducted at 24 h, 48 h, and 72 h after reaching target temperature. The primary outcome was 180 days neurological outcome assessed by Cerebral Performance Category score (CPC180) and the primary TTE outcome measure was s’. Secondary outcome measures were left ventricular ejection fraction (LVEF), global longitudinal strain (GLS), e’, E/e’ and tricuspid annular plane systolic excursion (TAPSE). Results Across all three scan time points s’ was not associated with neurological outcome (ORs: 24 h: 1.0 (95%CI: 0.7–1.4, p = 0.98), 48 h: 1.13 (95%CI: 0.9–1.4, p = 0.34), 72 h: 1.04 (95%CI: 0.8–1.4, p = 0.76)). LVEF, GLS, E/e’, and TAPSE recorded on serial TTEs following OHCA were neither associated with nor did they predict CPC180. Estimated median e’ at 48 h following TTM was 5.74 cm/s (95%CI: 5.27–6.22) in patients with good outcome (CPC180 1–2) vs. 4.95 cm/s (95%CI: 4.37–5.54) in patients with poor outcome (CPC180 3–5) (p = 0.04). Conclusions s’ assessed on serial TTEs in comatose survivors of OHCA treated with TTM was not associated with CPC180. Our findings suggest that serial TTEs in the early post-resuscitation phase during TTM do not aid the prognostication of neurological outcome following OHCA. Trial registration NCT02066753.

Abstract Introduction Cardiogenic shock (CS) due to myocardial infarction (MI) carries 30-day mortality rates as high as 50%. The vast majority of study cohorts assessing mortality in CS comprise both patients presenting with and without out-of-hospital cardiac arrest (OHCA). Patients with and without OHCA are likely to represent two distinctive entities, which may be problematic to combine in an intervention trial. Purpose The aim of the study was to compare CS due to MI patients presenting with and without OHCA in terms of patient characteristics and outcome. Methods In the period from 2010–2017 all patients admitted at two tertiary heart centres in Denmark with CS following MI were individually identified and validated through patient records. The two centres have a catchment area of 3.9 million citizens corresponding to two-thirds of the Danish population. Results A total of 1716 CS patients were identified, of which 42% presented with OHCA. OHCA patients were younger (mean 63 vs 67 years), more frequently male (85 vs 67%), had higher lactate concentration (median 6.2 vs 5.0 mmol/L) on admission and higher left ventricular ejection fraction (median 30 vs 25%) compared to patients without OHCA (p<0.0001 for all). Patients presenting with OHCA had lower 30-day mortality compared to patients without OHCA (49% vs. 57%, respectively, plogrank<0.0001, Figure). Cause of in hospital death differed markedly between the two groups. Not surprisingly, anoxic brain damage was the leading cause of in hospital death in the OHCA group (56%) and only seen in 4% of patients without OHCA. In contrast, cardiac failure was the main cause of death in hospital death among patients without OHCA (60%), compared to 27% in patients with OHCA (p<0.0001). Figure 1 Conclusion Among patients with CS due to MI, overall 30-day mortality was significantly lower in patients presenting with OHCA. Anoxic brain damage was the main cause of in hospital death among OHCA patients, whereas fatal heart failure prevailed in patients without OHCA. Combining these two groups in a single trial with one specific intervention seems inappropriate and likely to cause an imbalance in the signal-to-noise ratio.

Background: The benefit of emergency coronary angiography after resuscitation from out-of-hospital cardiac arrest is uncertain for patients without ST-segment elevation. The aim of this randomized trial was to evaluate the efficacy and safety of early coronary angiography and to determine the prevalence of acute coronary occlusion in resuscitated patients with out-of-hospital cardiac arrest without ST-segment elevation. Methods: Adult (>18 years) comatose survivors without ST-segment elevation after resuscitation from out-of-hospital cardiac arrest were prospectively randomized in a 1:1 fashion under exception to informed consent regulations to early coronary angiography versus no early coronary angiography in this multicenter study. Early angiography was defined as ≤120 minutes from arrival at the percutaneous coronary intervention–capable facility. The primary end point was a composite of efficacy and safety measures, including efficacy measures of survival to discharge, favorable neurologic status at discharge (Cerebral Performance Category score ≤2), echocardiographic measures of left ventricular ejection fraction >50%, and a normal regional wall motion score of 16 within 24 hours of admission. Adverse events included rearrest, pulmonary edema on chest x-ray, acute renal dysfunction, bleeding requiring transfusion or intervention, hypotension (systolic arterial pressure ≤90 mm Hg), and pneumonia. Secondary end points included the incidence of culprit vessels with acute occlusion. Results: The study was terminated prematurely before enrolling the target number of patients. A total of 99 patients were enrolled from 2015 to 2018, including 75 with initially shockable rhythms. Forty-nine patients were randomized to early coronary angiography. The primary end point of efficacy and safety was not different between the 2 groups (55.1% versus 46.0%; P =0.64). Early coronary angiography was not associated with any significant increase in survival (55.1% versus 48.0%; P =0.55) or adverse events (26.5% versus 26.0%; P =1.00). Early coronary angiography revealed a culprit vessel in 47%, with a total of 14% of patients undergoing early coronary angiography having an acutely occluded culprit coronary artery. Conclusions: This underpowered study, when considered together with previous clinical trials, does not support early coronary angiography for comatose survivors of cardiac arrest without ST elevation. Whether early detection of occluded potential culprit arteries leads to interventions that improve outcomes requires additional study.

Introduction: Despite the improvements in standardized cardiopulmonary resuscitation, survival remains low, mainly due to initial myocardial dysfunction and hemodynamic instability. Our goal was to compare the efficacy of two left ventricular assist devices on resuscitation and hemodynamic supply in a porcine model of ventricular fibrillation (VF) cardiac arrest. Methods: Seventeen anaesthetized pigs had 12 min of untreated VF followed by 6 min of chest compression and boluses of epinephrine. Next, a first defibrillation was attempted and pigs were randomized to any of the three groups: control (n = 5), implantation of an percutaneous left ventricular assist device (Impella, n = 5) or extracorporeal membrane oxygenation (ECMO, n = 7). Hemodynamic and myocardial functions were evaluated invasively at baseline, at return of spontaneous circulation (ROSC), after 10–30–60–120–240 min post-resuscitation. The primary endpoint was the rate of ROSC. Results: Only one of 5 pigs in the control group, 5 of 5 pigs in the Impella group, and 5 of 7 pigs in the ECMO group had ROSC (p < 0.05). Left ventricular ejection fraction at 240 min post-resuscitation was 37.5 ± 6.2% in the ECMO group vs. 23 ± 3% in the Impella group (p = 0.06). No significant difference in hemodynamic parameters was observed between the two ventricular assist devices. Conclusion: Early mechanical circulatory support appeared to improve resuscitation rates in a shockable rhythm model of cardiac arrest. This approach appears promising and should be further evaluated.

Abstract Aims Out-of-hospital cardiac arrest (OHCA) affects around 1/1000 person-years. Following return of spontaneous circulation (ROSC), the patient can manifest neurological impairment. A targeted temperature management (TTM) protocol is recommended to prevent hypoxic–ischaemic brain damage in patients with coma after cardiac arrest. Neuro-prognostication remains substantial for the prediction of clinical outcomes. To study clinical characteristics, overall survival, and neurological outcome of patients with Glasgow Coma Scale (GCS) &lt;8 after ROSC following an OHCA of presumed cardiac cause at our Institution. Secondly, to investigate determinants of a negative neurological outcome. Methods Observational retrospective study evaluating all patients with OHCA of presumed cardiac cause and with GCS &lt; 8 after ROSC treated in an intensive cardiac care unit of a tertiary centre. The study period was from January 2017 to December 2020. Results One-hundred and five patients out of 107 patients initially selected were included in the study (77% male, mean age 67 years). At 30 days, mortality was 41% and 53% of patients had a poor neurological outcome (Cerebral Performance Category, CPC, 3–5). Sixty-nine patients (66%) underwent TTM. In regard of the circumstances of OHCA, index event in a private place [OR = 3.12 (1.43–7.11), P = 0.005], ineffective rhythm changes during resuscitation manoeuvres [OR = 2.40 (1.05–5.47), P = 0.037] and a greater amount of adrenaline administered during resuscitation [OR = 1.62 (1.27–2.06), P &lt; 0.001] were related to a worse neurological outcome. A history of diabetes mellitus [OR = 3.35 (1.26–8.91), P = 0.015], blood lactates at presentation [OR = 1.33 (1.15—1.53), P &lt; 0.001], neuron-specific enolase (NSE) at presentation [OR = 1.055 (1.022–1.089), P &lt; 0.001] and as peak [OR = 1.034 (1.013–1.054), P &lt; 0.001] were associated with a worse neurological outcome. Among the neurological examinations, the presence of status epilepticus on the EEG [OR = 13.97 (1.73–113.02), P = 0.013] was a predictor of a poor neurological outcome. Treatment with targeted temperature management did not show a significant impact in terms of outcome at univariate analysis [OR = 1.226 (0.547–2.748), P = 0.62]. Two models were developed with multivariate logistic regression for the prediction of neurological outcome. The first one, on a statistical basis, considers pupil reactivity after ROSC, NSE as peak and left ventricular ejection fraction (AUC = 92%). The second model, on a clinical basis, considers age, first blood lactate value and NSE as peak (AUC = 89 %). Finally, the performance of the multiparametric MIRACLE score was tested in our population (AUC 0.81 for neurological outcome at 30 days). Conclusions In our population, at 30 days after cardiac arrest, survival rate and the rate of good neurological outcome were comparable to those of the major international registries and studies. Even though patients treated with TTM did not demonstrate significant differences in terms of neurological outcome, this might be related to study-sample size and patient selection. Results in the literature are still controversial on this topic. The MIRACLE score showed a good performance, making it suitable for clinical use in our population. Similarly, the proposed multivariate models are potentially useful for the elaboration of simple and effective prognostic scores in neurological risk stratification.
