Increased preload and echocardiographic assessment of diastolic function.

AIMS: Echocardiographic diastolic parameters are used to diagnose and monitor increased left ventricular filling pressure (LVFP) and we hypothesized that increased loading conditions cause increased E/e'. Our aim was to assess the effect of preload augmentation on diastolic parameters among both healthy subjects and subjects with known cardiac disease. METHODS AND RESULTS: We included 129 subjects merged from two cohorts; one dialysis cohort (n = 47) and one infusion cohort (n = 82). Echocardiography was performed immediately before and after hemodialysis (HD) or saline infusion, under low and high loading conditions. Elevated LVFP was defined as septal E/e' ≥ 15 and/or lateral E/e' ≥ 13 at high-loading conditions. The population was divided according to elevated LVFP (n = 31) and normal LVFP (n = 98). The load difference for the population was 972 ± 460 mL, with no differences in load difference between elevated and normal LVFP (p NS). The subjects with elevated LVFP were older (63 ± 11 vs. 46 ± 16 years, p < .001), and had lower LV ejection fraction (50 ± 14 vs. 59 ± 8.1%, p < .01). After augmented preload, EDV increased in the normal LVFP group (p < .01) but remained unchanged in the elevated LVFP group (p NS). Both E and e' increased among the subjects with normal LVFP, whereas E/e' remained unchanged (∆E/e' +.1 [-.5-1.2]), p NS). Among the subjects with elevated, LVFP we observed increased E but not e', resulting in significantly increased E/e' (∆ average E/e' +2.4 [0-4.0], p < .01). CONCLUSION: Augmented preload does not seem to affect E/e' among subjects with normal LVFP, whereas E/e' seems to increase significantly among subjects with elevated LVFP.

Lipid-lowering therapy after acute coronary syndromes: a multinational European survey.

BACKGROUND: Recent guidelines on acute coronary syndromes (ACS) recommend initiating lipid-lowering therapy (LLT) as early as possible to obtain >50% low-density-lipoprotein cholesterol (LDL-c) reduction and an LDL-c < 1.4 mmol/l. METHODS: A multinational European survey study of ACS patients between 2021-2022 and acquired data on LLT and lipid levels on admission and during 1-year posthospitalization. We compared plasma lipid changes and adherence to post-ACS lipid targets across two in-hospital LLT groups: high-intensity statin (HIS) monotherapy (mono-HIS) and a combination of HIS and ezetimibe (combo-HIS). RESULTS: Of 286 patients, 268 (94%) received in-hospital HIS and were included in the final analysis. Patients (median age: 61.1 years) had a median baseline LDL-c of 3.3 mmol/l. Mono-HIS was the predominant in-hospital LLT (72.4%). In-hospital combo-HIS was administered in 27.6% of the cases. Patients from high-income countries (n = 141) were more likely to receive in-hospital combo-HIS than patients from middle-income countries [n = 127; 38.3% vs. 15.7% patients, P < 0.001). One-year post-ACS, 50 (26.5%) patients from the mono-HIS group received ezetimibe. The target of LDL-c ≤ 55 mg/dl was reached in 85 patients (31.7%), without significant difference between study groups [mono-HIS: 56 (28.9%) and combo-HIS: 29 (39.2%) patients, P = 0.10]. The target of >50% reduction was achieved more frequently among the combo-HIS group than in the mono-HIS group (50.0% vs. 29.9%, respectively, P = 0.002). CONCLUSION: LDL-c targets were achieved in less than half of the patients post-ACS, regardless of the LLT regimen. Combo-HIS was initiated in-hospital post-ACS in only 28% and was associated with greater LDL-c reduction compared to a staged approach of mono-HIS with up-titration at follow-up.

Temporary mechanical circulatory support in infarct-related cardiogenic shock: an individual patient data meta-analysis of randomised trials with 6-month follow-up.

BACKGROUND: Percutaneous active mechanical circulatory support (MCS) devices are being increasingly used in the treatment of acute myocardial infarction-related cardiogenic shock (AMICS) despite conflicting evidence regarding their effect on mortality. We aimed to ascertain the effect of early routine active percutaneous MCS versus control treatment on 6-month all-cause mortality in patients with AMICS. METHODS: In this individual patient data meta-analysis, randomised controlled trials of potential interest were identified, without language restriction, by querying the electronic databases MEDLINE via PubMed, Cochrane Central Register of Controlled Trials, and Embase, as well as ClinicalTrials.gov, up to Jan 26, 2024. All randomised trials with 6-month mortality data comparing early routine active MCS (directly in the catheterisation laboratory after randomisation) versus control in patients with AMICS were included. The primary outcome was 6-month all-cause mortality in patients with AMICS treated with early routine active percutaneous MCS versus control, with a focus on device type (loading, such as venoarterial extracorporeal membrane oxygenation [VA-ECMO] vs unloading) and patient selection. Hazard ratios (HRs) of the primary outcome measure were calculated using Cox regression models. This study is registered with PROSPERO, CRD42024504295. FINDINGS: Nine reports of randomised controlled trials (n=1114 patients) were evaluated in detail. Overall, four randomised controlled trials (n=611 patients) compared VA-ECMO with a control treatment and five randomised controlled trials (n=503 patients) compared left ventricular unloading devices with a control treatment. Two randomised controlled trials also included patients who did not have AMICS, who were excluded (55 patients [44 who were treated with VA-ECMO and 11 who were treated with a left ventricular unloading device]). The median patient age was 65 years (IQR 57-73); 845 (79·9%) of 1058 patients with data were male and 213 (20·1%) were female. No significant benefit of early unselected MCS use on 6-month mortality was noted (HR 0·87 [95% CI 0·74-1·03]; p=0·10). No significant differences were observed for left ventricular unloading devices versus control (0·80 [0·62-1·02]; p=0·075), and loading devices also had no effect on mortality (0·93 [0·75-1·17]; p=0·55). Patients with ST-elevation cardiogenic shock without risk of hypoxic brain injury had a reduction in mortality with MCS use (0·77 [0·61-0·97]; p=0·024). Major bleeding (odds ratio 2·64 [95% CI 1·91-3·65]) and vascular complications (4·43 [2·37-8·26]) were more frequent with MCS use than with control. INTERPRETATION: The use of active MCS devices in patients with AMICS did not reduce 6-month mortality (regardless of the device used) and increased major bleeding and vascular complications. However, patients with ST-elevation cardiogenic shock without risk of hypoxic brain injury had a reduction in mortality after MCS use. Therefore, the use of MCS should be restricted to certain patients only. FUNDING: The Heart Center Leipzig at Leipzig University and the Foundation Institut für Herzinfarktforschung.

Do DanGer-SHOCK-like patients benefit from VA-ECMO treatment in infarct-related cardiogenic shock? results of an individual patient data meta-analysis.

AIMS: In a recent meta-analysis of randomized controlled trials, routine use of veno-arterial ECMO (VA-ECMO) did not improve outcomes in patients with acute myocardial infarction-related cardiogenic shock (AMI-CS), while a microaxial flow pump reduced mortality in a selected group of patients with AMI-CS in the DanGer-Shock trial. METHODS AND RESULTS: Individual patient data of patients included in four randomized clinical trials investigating the routine use of VA-ECMO in AMI-CS were centrally analysed. For the purpose of this sub-analysis, DanGer-Shock-like patients were analysed (STEMI only, presumed low likelihood of brain injury). The primary endpoint was 180-day all-cause mortality. A total of 202 patients (106 randomized to VA-ECMO and 96 to control) were included. There were no differences in baseline characteristics, angiographic and interventional features between the two groups. Mortality after 6 months was numerically lower with VA-ECMO between the groups [45% in VA-ECMO group vs. 51% in control group; hazard ratio, 0.84; 95% confidence interval (CI), 0.56-1.26], while major bleeding (OR, 2.24; 95% CI, 1.08-4.64) and peripheral vascular complications (OR, 3.65; 95% CI, 1.15-11.56) were increased with the use of VA-ECMO. CONCLUSION: In this exploratory subgroup analysis in patients with CS, STEMI, and a low likelihood of brain injury, there was no mortality benefit with the routine use of VA-ECMO. However, as indicated by the large confidence intervals, the statistical power was limited to draw definite conclusions.

The Pupillary Light-Off Reflex in Acute Disorders of Consciousness.

BACKGROUND: In intensive care patients with disorders of consciousness, the pupillary light reflex is a measure of pupillary parasympathetic function. By contrast, the pupillary light-off reflex leads to pupil dilation in response to an abrupt change from light to darkness ("light-off") and reflects combined parasympathetic and sympathetic pupillary function. To our knowledge, this reflex has not been systematically investigated in patients with disorders of consciousness. We hypothesized that the pupillary light-off reflex correlates with consciousness levels after acute brain injury. METHODS: From November 2022 to March 2023, we enrolled 100 study participants: 25 clinically unresponsive (coma or unresponsive wakefulness syndrome) and 25 clinically low-responsive (minimally conscious state or better) patients from the intensive care units of a tertiary referral center, and 50 age-matched and sex-matched healthy controls. Exclusion criteria were active or chronic eye disease. We used automated pupillometry to assess the pupillary light-off reflex and the pupillary light reflex of both eyes under scotopic conditions in all study participants. RESULTS: The pupillary light-off reflex was strongly correlated with consciousness levels (r = 0.62, p < 0.001), the increase in pupillary diameters being smallest in unresponsive patients (mean ± standard deviation 20% ± 21%), followed by low-responsive patients (mean ± standard deviation 47% ± 26%) and healthy controls (mean ± standard deviation 67% ± 17%; p < 0.001). Similar yet less pronounced patterns were observed for the pupillary light reflex. Twenty-one of 25 (84%) unresponsive patients had preserved pupillary light reflexes, but only seven (28%) had fully preserved pupillary light-off reflexes (p < 0.0001). Of these 7 patients, five (71%) regained awareness. CONCLUSIONS: The pupillary light-off reflex may be more sensitive to consciousness levels than the pupillary light reflex. The clinical implications of this finding seem worthy of further investigation, particularly regarding possible benefits for neuromonitoring and prognostication after brain injury.

Multiomic biomarkers after cardiac arrest.

Cardiac arrest is a sudden cessation of heart function, leading to an abrupt loss of blood flow and oxygen to vital organs. This life-threatening emergency requires immediate medical intervention and can lead to severe neurological injury or death. Methods and biomarkers to predict neurological outcome are available but lack accuracy. Such methods would allow personalizing healthcare and help clinical decisions. Extensive research has been conducted to identify prognostic omic biomarkers of cardiac arrest. With the emergence of technologies allowing to combine different levels of omics data, and with the help of artificial intelligence and machine learning, there is a potential to use multiomic signatures as prognostic biomarkers after cardiac arrest. This review article delves into the current knowledge of cardiac arrest biomarkers across various omic fields and suggests directions for future research aiming to integrate multiple omics data layers to improve outcome prediction and cardiac arrest patient's care.

Prehospital Pulse-Dose Glucocorticoid in ST-Segment Elevation Myocardial Infarction: The PULSE-MI Randomized Clinical Trial.

Importance: In patients with ST-segment elevation myocardial infarction (STEMI), acute inflammation is related to the extent of myocardial damage and may increase infarct size. Thus, administration of pulse-dose glucocorticoid in the very early phase of infarction may reduce infarct size. Objective: To determine the cardioprotective effect of prehospital pulse-dose glucocorticoid in patients with STEMI. Design, Setting, and Participants: This was a 1:1 investigator-initiated, blinded, placebo-controlled, randomized clinical trial conducted between November 14, 2022, and October 17, 2023, with last follow-up on January 17, 2024. Patients 18 years and older with less than 12 hours of acute chest pain and STEMI were included in the prehospital setting throughout the Region Zealand and Capital Region of Denmark and transferred to Rigshospitalet, Denmark. Intervention: Patients were randomly allocated to intravenous glucocorticoid (methylprednisolone, 250 mg) or placebo in the prehospital setting. Main Outcomes and Measures: The primary outcome was final infarct size on cardiac magnetic resonance (CMR) at 3 months. The power calculation was based on an anticipated final infarct size of 13%. Secondary outcomes included CMR outcomes on acute scan and at 3 months, peak of cardiac biomarkers, clinical end points at 3 months, and adverse events. Results: Of 530 included patients (median [IQR] age, 65 [56-75] years; 418 male [78.9%]) with STEMI, 401 (76%) were assessed for the primary outcome, with 198 patients treated with glucocorticoid and 203 with placebo. Median final infarct size was similar in the treatment groups (glucocorticoid, 5%; IQR, 2%-11% vs placebo, 6%; IQR, 2%-13%; P = .24). Compared with placebo, the glucocorticoid group had smaller acute infarct size (odds ratio, 0.78; 95% CI, 0.61-1.00), less microvascular obstruction (relative risk ratio, 0.83; 95% CI, 0.71-0.99), and greater acute left ventricular ejection fraction (mean difference, 4.44%; 95% CI, 2.01%-6.87%). Other secondary outcomes were similar in both groups. Conclusions and Relevance: In patients with STEMI, treatment with prehospital pulse-dose glucocorticoid did not reduce final infarct size after 3 months. However, the trial was likely underpowered as the final infarct size was smaller than anticipated. The glucocorticoid group had improved acute parameters compared with placebo.

Inflammatory response after prehospital high-dose glucocorticoid to patients resuscitated from out-of-hospital cardiac arrest: A sub-study of the STEROHCA trial.

BACKGROUND: The post-cardiac arrest syndrome (PCAS) after out-of-hospital cardiac arrest (OHCA) is characterized by a series of pathological events, including inflammation. In the randomized "STERoid for OHCA" (STEROHCA) trial, prehospital high-dose glucocorticoid decreased interleukin (IL) 6 and C-reactive protein levels following resuscitated OHCA. The aim of this predefined sub-study was to assess the inflammatory response the first three days of admission. METHODS: The STEROHCA trial enrolled 137 OHCA patients randomized to either a single prehospital injection of methylprednisolone 250 mg or placebo. Inflammatory markers, including pro- and anti-inflammatory cytokines, were analyzed in plasma samples, from 0-, 24-, 48-, and 72 h post-admission. Mixed-model analyses were applied using log-transformed data to assess group differences. RESULTS: The 137 patients included in this sub-study had a median age of 67 years (57 to 74), and the 180-day survival rates were 75% (n = 51/68) and 64% (n = 44/69) in the glucocorticoid and placebo group, respectively. A total of 130 (95%) patients had at least one plasma sample available. The anti-inflammatory cytokine IL-10 was increased at hospital admission in the glucocorticoid group (ratio 2.74 (1.49-5.05), p = 0.006), but the intervention showed the strongest effect after 24 h, decreasing pro-inflammatory levels of IL-6 (ratio 0.06 (0.03-0.10), p < 0.001), IL-8 (ratio 0.53 (0.38-0.75), p < 0.001), macrophage chemokine protein-1 (MCP-1, ratio 0.02 (0.13-0.31), p < 0.001), macrophage inflammatory protein-1-beta (MIP-1b, ratio 0.28 (0.18-0.45), p < 0.001), and tumor necrosis factor-α (TNF-α, ratio 0.6 (0.4-0.8), p = 0.01). CONCLUSION: Administering high-dose glucocorticoid treatment promptly after resuscitation from OHCA influenced the inflammatory response with a reduction in several systemic proinflammatory cytokines after 24 h.

Microaxial flow pump (Impella CP®) in patients with ST-elevation myocardial infarction complicated by cardiogenic shock.

Cardiogenic shock due to ST-elevation myocardial infarction remains a critical condition with a high mortality rate, even with current revascularization techniques. The use of mechanical circulatory support, such as the microaxial flow pump device (Impella CP®), presents a promising approach to enhance cardiac output and systemic perfusion. The DanGer Shock trial explored the efficacy of Impella CP® in addition to standard care compared to standard care alone in improving survival outcomes for these patients. Despite the potential for increased adverse events, the Impella CP® device significantly reduces mortality in patients with ST-elevation myocardial infarction complicated by cardiogenic shock. Future research should focus on refining patient selection criteria and minimizing device-related complications to maximize the therapeutic benefits of mechanical circulatory support in this critical population.

Validating quantitative pupillometry thresholds for neuroprognostication after out-of-hospital cardiac arrest. A predefined substudy of the Blood Pressure and Oxygenations Targets After Cardiac Arrest (BOX)-trial.

PURPOSE: Out-of-hospital cardiac arrest (OHCA) survivors face significant risks of complications and death from hypoxic-ischemic brain injury leading to withdrawal of life-sustaining treatment (WLST). Accurate multimodal neuroprognostication, including automated pupillometry, is essential to avoid inappropriate WLST. However, inconsistent study results hinder standardized threshold recommendations. We aimed to validate proposed pupillometry thresholds with no false predictions of unfavorable outcomes in comatose OHCA survivors. METHODS: In the multi-center BOX-trial, quantitative measurements of automated pupillometry (quantitatively assessed pupillary light reflex [qPLR] and Neurological Pupil index [NPi]) were obtained at admission (0 h) and after 24, 48, and 72 h in comatose patients resuscitated from OHCA. We aimed to validate qPLR < 4% and NPi ≤ 2, predicting unfavorable neurological conditions defined as Cerebral Performance Category 3-5 at follow-up. Combined with 48-h neuron-specific enolase (NSE) > 60 µg/L, pupillometry was evaluated for multimodal neuroprognostication in comatose patients with Glasgow Motor Score (M) ≤ 3 at ≥ 72 h. RESULTS: From March 2017 to December 2021, we consecutively enrolled 710 OHCA survivors (mean age: 63 ± 14 years; 82% males), and 266 (37%) patients had unfavorable neurological outcomes. An NPi ≤ 2 predicted outcome with 0% false-positive rate (FPR) at all time points (0-72 h), and qPLR < 4% at 24-72 h. In patients with M ≤ 3 at ≥ 72 h, pupillometry thresholds significantly increased the sensitivity of NSE, from 42% (35-51%) to 55% (47-63%) for qPLR and 50% (42-58%) for NPi, maintaining 0% (0-0%) FPR. CONCLUSION: Quantitative pupillometry thresholds predict unfavorable neurological outcomes in comatose OHCA survivors and increase the sensitivity of NSE in a multimodal approach at ≥ 72 h.

Anthropometric measures and long-term mortality in non-ischaemic heart failure with reduced ejection fraction: Questioning the obesity paradox.

AIMS: Although body mass index (BMI) is the most commonly used anthropometric measure to assess adiposity, alternative indices such as the waist-to-height ratio may better reflect the location and amount of ectopic fat as well as the weight of the skeleton. METHODS AND RESULTS: The prognostic value of several alternative anthropometric measures was compared with that of BMI in 1116 patients with non-ischaemic heart failure with reduced ejection fraction (HFrEF) enrolled in DANISH. The association between anthropometric measures and all-cause death was adjusted for prognostic variables, including natriuretic peptides. Median follow-up was 9.5 years (25th-75th percentile, 7.9-10.9). Compared to patients with a BMI 18.5-24.9 kg/m2 (n = 363), those with a BMI ≥25 kg/m2 had a higher risk of all-cause and cardiovascular death, although this association was only statistically significant for a BMI ≥35 kg/m2 (n = 91) (all-cause death: hazard ratio [HR] 1.78, 95% confidence interval [CI] 1.28-2.48; cardiovascular death: HR 2.46, 95% CI 1.69-3.58). Compared to a BMI 18.5-24.9 kg/m2, a BMI <18.5 kg/m2 (n = 24) was associated with a numerically, but not a significantly, higher risk of all-cause and cardiovascular death. Greater waist-to-height ratio (as an exemplar of indices not incorporating weight) was also associated with a higher risk of all-cause and cardiovascular death (HR for the highest vs. the lowest quintile: all-cause death: HR 2.11, 95% CI 1.53-2.92; cardiovascular death: HR 2.17, 95% CI 1.49-3.15). CONCLUSION: In patients with non-ischaemic HFrEF, there was a clear association between greater adiposity and higher long-term mortality. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov NCT00542945.

Imaging in acute percutaneous mechanical circulatory support in adults. A clinical consensus statement of the Association for Acute CardioVascular Care (ACVC) of the ESC, the European Association of Cardiovascular Imaging (EACVI) of the ESC and the European branch of the Extracorporeal Life Support Organization (EuroELSO).

The use of temporary mechanical circulatory support (tMCS) in cardiogenic shock patients has increased during the last decades with most management strategies relying on observational studies and expert opinion, including hemodynamic monitoring, device selection and timing of support institution/duration. In this context, imaging has a pivotal role throughout the patient pathway, from identification to initiation, monitoring and weaning. This manuscript summarizes the consensus of an expert panel from the European Society of Cardiology Association for Acute CardioVascular Care, the European Association of CardioVascular Imaging and the European Extracorporeal Life Support Organization, providing the rationale for and practical guidance of imaging to tMCS based on existing evidence and consensus on best current practice.

Brain network changes and cognitive function after cardiac arrest.

Survival rates after out-of-hospital cardiac arrest have improved over the past two decades. Despite this progress, long-term cognitive impairment remains prevalent even in those with early recovery of consciousness after out-of-hospital cardiac arrest; however, little is known about the determinants and underlying mechanisms. We utilized the REcovery after cardiac arrest surVIVAL cohort of out-of-hospital cardiac arrest survivors who fully regained consciousness to correlate cognition measurements with brain network changes using resting-state functional MRI and the Montreal Cognitive Assessment at hospital discharge and a comprehensive neuropsychological assessment at three-month follow-up. About half of out-of-hospital cardiac arrest survivors displayed cognitive impairments at discharge, and in most, cognitive deficits persisted at three-month follow-up, particularly in the executive and visuospatial functions. Compared to healthy controls, out-of-hospital cardiac arrest survivors exhibited increased connectivity between resting-state networks, particularly involving the frontoparietal network. The increased connectivity between the frontoparietal and visual networks was associated with less favourable cognitive outcomes (ß = 14.0, P = 0.01), while higher education seemed to confer some cognitive protection (ß = -2.06, P = 0.03). In sum, the data highlight the importance of subtle cognitive impairment, also in out-of-hospital cardiac arrest survivors who are eligible for home discharge, and the potential of functional MRI to identify alterations in brain networks correlating with cognitive outcomes.

Cardiac tamponade due to right coronary artery perforation following pacemaker implantation: a case report.

Background: Cardiac tamponade due to perforation of a cardiac chamber is a rare complication occurring in only 0.3% of patients undergoing permanent pacemaker (PM) implantation. Notably, perforation of the right coronary artery (RCA) following permanent PM implantation has only been reported twice in the literature. We report a rare case of RCA perforation leading to life-threatening cardiac tamponade with symptom onset 4 days after PM implantation. Case summary: A 75-year-old woman underwent permanent PM implantation without any difficulties in placing pacemaker leads and with good thresholds. Four days later, the patient was readmitted in a state of shock due to cardiac tamponade. A blood gas analysis on the bloody pericardial effusion raised suspicion of ongoing arterial bleeding. A CT scan ruled out aortic dissection; instead, the source of bleeding was identified as a perforation in the RCA, which was managed surgically. Discussion: This case highlights the necessity of coronary artery perforation being among the differential diagnoses of cardiac tamponade after PM implantation, and it stresses the usefulness of performing a blood gas analysis on the bloody pericardial effusion.

Evaluating neurocognitive outcomes in out-of-hospital cardiac arrest survivors: A comparative study of performance-based and reported measures.

AIMS: To (1) describe the prevalence of cognitive dysfunctions using performance-based and reported measures, and (2) explore the correlations between selected performance-based, patient-reported, and observer-reported neurocognitive outcome measures three months after hospital discharge in a population of out-of-hospital cardiac arrest (OHCA) survivors. METHODS: Data from 193 OHCA survivors was derived from the Danish multicenter REVIVAL cohort study. At three months, four subtests of the performance-based Delis-Kaplan Executive Function System (D-KEFS) (Trail making, Color-word interference, Verbal fluency, and Figure design), the patient-reported Behavior Rating Inventory of Executive Function - Adult (BRIEF-A), and the observer-reported 16-item Short Form (SF) Informant Questionnaire on Cognitive Decline after Cardiac Arrest (SF-16 IQCODE-CA) were collected. Spearman's rank coefficient correlation analysis was performed to examine correlations between D-KEFS, BRIEF-A, and SF-16 IQCODE-CA. RESULTS: Overall, 21% of survivors exhibited impairment in executive functioning using the D-KEFS subtest Color-word interference, while only 9% self-reported executive impairment (BRIEF-A) and 7% of relatives reported cognitive decline (SF-16 IQCODE-CA) in survivors at three months post-arrest. All correlations between D-KEFS, BRIEF-A and SF-16 IQCODE-CA were negligible to low. CONCLUSION: The results of this REVIVAL substudy suggest that although the performance-based and reported measures did not correlate, dual neurocognitive screening tools containing both a self-reported and an informant-reported version may have the potential to detect executive discrepancies in the return to everyday life and guide targeted neurorehabilitation after OHCA.

Relevance of age and hypertension for blood pressure targets in comatose survivors of cardiac arrest: a BOX-trial sub-study.

AIMS: To assess whether the optimal mean arterial blood pressure (MAP) target after out-of-hospital cardiac arrest (OHCA) is influenced by age and a history of arterial hypertension. METHODS AND RESULTS: A post hoc analysis of data from the Blood Pressure and Oxygenation Targets in Post Resuscitation Care trial. The trial included 789 comatose patients randomized to a MAP target of 63 or 77 mmHg. The primary outcome of this sub-study was 1-year all-cause mortality. Cox proportional hazards regression and restricted cubic splines were used to examine whether prevalent hypertension and age modified the effect of low vs. high MAP target on all-cause mortality. Of the 789 patients randomized, 393 were assigned to a high MAP target, and 396 to a low MAP target. Groups were well-balanced for mean age (high MAP target 63 ± 13 years vs. low 62 ± 14 years) and hypertension (45 vs. 47%, respectively). At 1 year, the primary outcome occurred in 143 patients (36%) with a high MAP target and 138 (35%) with a low MAP target. The risk of the primary outcome increased linearly with increasing age (P < 0.001). The effect of a high vs. low MAP target on the primary outcome was modified by age when tested continuously, potentially favouring a low MAP target in younger patients (P for interaction = 0.03). Prevalent hypertension did not modify the effect of a high vs. low MAP target on the primary outcome (P for interaction = 0.67). CONCLUSION: Among patients resuscitated after OHCA, older patients and those with a history of hypertension did not benefit from a high MAP target.

Future for cardiogenic shock research.

PURPOSE OF REVIEW: To discuss future research themes and study design in cardiogenic shock. RECENT FINDINGS: Cardiogenic shock research faces multiple challenges, hindering progress in understanding and treating this life-threatening condition. Cardiogenic shock's heterogeneous nature poses challenges in patient selection for clinical trials, potentially leading to variability in treatment responses and outcomes. Ethical considerations arise due to the acuity and severity of the condition, posing challenges in obtaining informed consent and conducting randomized controlled trials where time to treatment is pivotal. SUMMARY: This review discusses research in this area focusing on the importance of phenotyping patients with cardiogenic shock, based on artificial intelligence, machine learning, and unravel new molecular mechanisms using proteomics and metabolomics. Further, the future research focus in mechanical circulatory support and targeting inflammation is reviewed. Finally, newer trial designs including adaptive platform trials are discussed.

Ventricular septal defect complicating acute myocardial infarction: diagnosis and management. A Clinical Consensus Statement of the Association for Acute CardioVascular Care (ACVC) of the ESC, the European Association of Percutaneous Cardiovascular Interventions (EAPCI) of the ESC and the ESC Working Group on Cardiovascular Surgery.

Ventricular septal defects are a rare complication after acute myocardial infarction with a mortality close to 100% if left untreated. However, even surgical or interventional closure is associated with a very high mortality and currently no randomized controlled trials are available addressing the optimal treatment strategy of this disease. This state-of-the-art review and clinical consensus statement will outline the diagnosis, hemodynamic consequences and treatment strategies of ventricular septal defects complicating acute myocardial infarction with a focus on current available evidence and a focus on major research questions to fill the gap in evidence.
