December 2024 Highlights
With warmth and excitement, we proudly present the final issue of European Heart Journal: Acute Cardiovascular Care in 2024! As the year closes, we’re excited to bring you a collection of thought-provoking and impactful articles — perfect reading for winter nights.
This issue features three groundbreaking research papers, two perspectives on leading-edge clinical trials, and an insightful educational piece on ethics in cardiac care research.
- Jarle Jortveit’s extensive Norwegian cohort study, highlights the stark outcomes for patients with acute myocardial infarction (AMI) complicated by either out-of-hospital (OHCA) or in-hospital cardiac arrest (IHCA). Analyzing over 105,000 AMI patients, the study found in-hospital mortality rates of 28% for OHCA and a striking 49% for IHCA. While survivors of OHCA achieved long-term survival comparable to those without cardiac arrest. In contrast, IHCA survivors continue to face elevated long-term mortality. These results emphasize the need for targeted interventions, particularly for IHCA patients who remain vulnerable post-discharge. Read more
- Our 2 Perspectives capture the latest exciting content from the prominent Autumn Cardiology conferences of 2024, including this year’s Transcatheter Therapeutics meeting in Washington and the American Heart Association Scientific Sessions in Chicago. Highlights include the SYNERGY (OASIS-9) trial, examining the impact of colchicine and spironolactone on post-AMI outcomes, and the GLORIUS trial, which contrasts oxygenation strategies during coronary and aortic surgeries. The former includes a trial interpretation from Dr. JC Tardif, principal investigator of the COLCOT trial, where he provides insights and interprets the data in the context of his own trial results. Read more
- Highly in the lineup, Mads Dam Lyhne’s study takes a closer look at the prognostic power of the Tricuspid Annular Plane Systolic Excursion/ Pulmonary Artery Systolic Pressure (TAPSE/PASP) ratio in evaluating patients with acute pulmonary embolism. Drawing from the extensive RIETE (Registro Informatizado de Enfermedad TromboEmbólica) registry data, this study spans 4,478 patients across European Society of Cardiology-defined risk groups. A decrease in TAPSE/PASP ratio emerged as a significant predictor of 30-day mortality, particularly in intermediate-high risk patients where rates escalated to 3.4%. Impressively, each 0.1 decrease in TAPSE/PASP ratio upped mortality odds by 26%. This finding confirms TAPSE/PASP as a valuable risk-stratification tool for clinical care, enabling safer decision-making on the need for hospitalization. Read more
- Also in this issue, John W. Pickering’s team brings a real-world evaluation of point-of-care (POC) high-sensitivity troponin I (hs-cTnI) testing. Implemented as the primary troponin assay in the emergency department (ED), POC hs-cTnI testing reduced patient length of stay by an average of 32 minutes, translating to 21.4 fewer patient-hours each day. With comparable safety outcomes to traditional methods, these findings highlight the promise of POC hs-cTnI in boosting ED efficiency and patient flow. This efficient approach could transform patient care by easing emergency department crowding without compromising safety. Read more
- Lastly, an educational piece by Neal Dickert tackles ethical complexities in cardiac critical care research, focusing on informed consent in high-stakes scenarios. Dickert’s review outlines practical strategies to respect patient autonomy while advancing urgently needed cardiac research, spotlighting scenarios where prospective consent may be waived responsibly.

November 2024 Highlights
Welcome to the November issue of the European Heart Journal Acute Cardiovascular Care! As we transition into the final months of the year, the days may be getting shorter, but the warmth in our field remains as we shine a spotlight on groundbreaking developments in cardiovascular care. This month’s edition brings a fresh perspective to some of the most pressing challenges in acute cardiovascular care, from innovative treatments for electrical storm (ES) to novel insights into the microcirculation in cardiogenic shock (CS). With each study, we edge closer to improving patient outcomes in life-threatening scenarios.
1. Enrico Baldi et al. demonstrated that the early use of percutaneous stellate ganglion block (PSGB) led to a dramatic reduction in arrhythmic events within the first hour, paving the way for safer, more effective interventions. PSGB offers new hope with potential to prevent progression to refractory ES—a breakthrough in an area where rapid intervention is critical. Although the study invites further exploration through randomized trials, the results are promising and may redefine how we approach ES in its early stage.
2. Maxwell Hockstein et al. shed the light into often-underdiagnosed condition of cor pulmonale in acute respiratory distress syndrome (ARDS). Their analysis reveals that cor pulmonale is associated with a 50% higher mortality rate, emphasizing the need for early identification. By examining factors such as pulmonary artery pulsatility index and arterial elastance (Ea), the study highlights that traditional metrics, including pH and PaO2, are less reliable predictors. This work stresses the necessity for multimodal diagnostics to better understand right ventricular-pulmonary artery coupling and prevent complications in ARDS—a call for greater awareness and proactive management.
3. Guido Tavazzi et al. offer a broad view of the evolving epidemiology of CS, examining data from over 11 000 ICU admissions in Italy. Their study reveals a shift from the traditional ischaemic causes to non-ischaemic etiologies and that right heart failure portends the highest mortality risk among CS patients. This trend potentially highlights the importance of early recognition and tailored interventions. As CS remains a condition with mortality rates hovering near 50%, this study underscores the need for integrated, multidisciplinary care strategies to improve survival outcomes.
4. On the front of mental health Leissner et al. tackle an often-overlooked consequence of cardiac care: the psychological impact of beta-blockers on patients recovering from myocardial infarction (MI). Drawing from the REDUCE-AMI trial, the authors found that while beta-blockers are associated with an increase in depressive symptoms, anxiety levels remain largely unaffected. Although the rise in depressive symptoms was modest, this finding reminds us of the importance of considering the mental health implications when managing MI patients, especially in those with preserved left ventricular ejection fraction. As we deepen our understanding of the interplay between cardiovascular and mental health, this study highlights the need for a holistic approach to cardiovascular patient care.
5. In a fascinating diagnostic advance, Juhani K.E. Airaksinen's study presents a novel way to distinguish between Takotsubo syndrome (TTS) and MI using cardiac troponin T (cTnT) immunoassays. The study’s discovery that TTS patients exhibit a significantly lower ratio of long to total cTnT compared to MI patients could offer a more precise diagnostic tool. While further research is needed to validate these findings with this investigational method, the potential for early differentiation between these two conditions could have a profound impact on treatment decisions, offering clinicians a powerful future tool in their diagnostic arsenal.
6. Rounding out this month’s issue is our educational paper from Christian Jung et al.9, which advocates for a more nuanced approach to CS management. By shifting focus from macrocirculation to microcirculatory dysfunction, this paper makes a compelling case for integrating microcirculation assessments into clinical practice. The authors emphasize that while advances in microcirculation-guided therapies hold great promise, their full potential has yet to be realized. More research is needed to bridge the gap between theoretical benefits and practical application in the ICU setting.
As we close this November issue, we invite our readers to engage with these pioneering studies, which collectively push the boundaries of cardiovascular care. We are excited about the discoveries shared in this edition, and we thank the authors for their invaluable contributions to our understanding of acute cardiovascular conditions. Together, let us continue to explore new horizons, expanding the possibilities of what can be achieved in the care of critically ill patients. Stay with us as we move into the final months of the year, energised, and optimistic about the future of our field.
October 2024 Highlights

Nutritional support during ICU stay - a stepwise approach towards better outcomes
Nutritional support plays an important role in management of critically ill patients, especially patients with acute heart failure, acute coronary syndrome, post-cardiac-arrest patients and patients with cardiogenic shock.
Nutritional support in acute heart failure
The nutritional risk and prevalence of malnutrition is high in patients with acute heart failure (up to 40%) due to bowel ischemia, microcirculatory failure, and malabsorption. Although adequate nutrition might play an important role in improving outcomes, studies on this matter are still lacking.
Nutritional support for these patients is based on general principles- early nutritional assessment, form of administration and assessment of nutritional risk. It is recommended to start enteral feeding in the first 48h upon CICU admission. In the acute phase (<72h) it is best to implement hypocaloric nutrition with adequate substitution of micronutrients.
Parenteral feeding can be associated with higher risk of infection, and it is recommended as first line in case of severe gastrointestinal dysfunction. However, early parenteral feeding is recommended in severely malnourished patients.
Nutritional support in acute coronary syndrome
Malnutrition is these patients may be associated with worsening outcomes. The same principles apply as for critically ill patients.
Nutritional support after cardiac arrest
Patients after suffering cardiac arrest may require close monitoring, especially if receiving ECLS for refractory cardiac arrest. In those patients’ enteral nutrition should be introduced with caution, as rates of intestinal ischemia are higher. Delayed feeding is associated with better outcomes. Studies on this field are needed to create uniform protocols of management of these patients.
Nutritional support in cardiogenic shock
As we all know, cardiogenic shock is a low cardiac output state secondary to cardiac dysfunction, leading to end-organ hypoperfusion and tissue hypoxia. During this condition mesenteric arteriolar vasoconstriction plays a major role in trying to maintain systemic blood pressure. Together with venous congestion it leads to decrease in local perfusion and increased risk of bowel ischemia.
If enteral feeding is started in this highly vulnerable hemodynamic state, there is a risk of mesenteric ischemia. Starting early enteral feeding is still controversial. It may be beneficial to do a permissive underfeeding in the first few days, especially in patients who require use of vasopressors. The incidence of proven bowel ischemia using those protocols was <1%.
Having in mind the incidence and severity of cardiovascular diseases requiring CICU admission, comprehensive multidisciplinary approach to nutritional support is needed to optimize care of critically ill patients. Further research is needed to try to obtain uniform and individualized protocols that could improve patient survival, duration of ICU stay and quality of life after CICU admission.
March 2024 Highlights
The light in the end of the tunnel – unrevealing mechanisms of ventricular fibrillation during the first ST elevation myocardial infarction by the use of proteonomics.
Stampe et al. conducted a study using proteonomics that unrevealed that 26 proteins are associated with ventricular fibrillation. Pending further analysis two of the proteins were strongly associated with VF (ACTBL2, F13A1). The findings of this study represent a groundbreaking moment that points the light towards further investigation of early VF in ST elevation myocardial infarction.
Embrace the challenge – the role of ventricular assist device in management of fulminant myocarditis
The study by Takahito Nasu et al. represent a pioneering large-scale registry study using data from Japanese Registry for Percutaneous Ventricular Assist Devices. Use of Impella device showed better success rate in comparison with ECPELLA. Having in mind the high percentage of adverse events further investigation is needed to optimize patient selection and treatment in this matter.
Deep dive into pulmonary embolism – identifying early predictors affects the outcome?
Zuin et al. deal with “Early predictors of clinical deterioration in intermediate-high risk pulmonary embolism” Their educational paper is complemented by a clinical consensus statement from the Association for Acute Cardiovascular Care that outlines the diagnostic and treatment pathways for acute right ventricular failure secondary to acutely increased right ventricular afterload.
Triglyceride deposit cardiomyovasculopathy (TGCV) – rare or just undiagnosed condition?
Nakano et al. introduce us to TGCV by conducting a study on 400 patients with ACS and 148 patients with diabetes and ACS. The study reports 4.3-5.4% prevalence emphasizing the need for further investigation and risk stratification of these patients, having in mind that they may present with diffuse coronary artery stenosis.
February 2024 Highlights
Cardiogenic shock patients on VA-ECMO – individual approach as the solution in prediction and reduction of complications?
VA-ECMO is a well-established method of treating patients with cardiogenic shock. But the risk of complications is still very high. Benedict N. Beer et al. conducted a retrospective multicenter cohort study with the aim to accurately describe the risk of complications and mortality events and to evaluate possible predictors of such events in those patients.
The study showed that the majority of 30-day survival patients treated with VA-ECMO had favorable neurological outcome (CPC 1/2). The presence of AEs, which are more common in women, are strongly associated with worsened neurological outcome and 30-day survival.
Further studies are needed to identify patients that could benefit from this strategy, having in mind the high risk of complications, whose prediction is still challeging and in need for RCTs. One possible solution might be the use of ECMELLA strategy that may reduce typical VA-ECMO complications but the strong evidence is still lacking. Patient selection might be improved by forming the multidisciplinary cardiogenic shock teams worldwide.
January 2024 Highlights
Sex-specific 99th percentile high-sensitivity cardiac troponin assays – are we there yet?
Dr. Maria Rubini Gimenez discusses the diagnostic and prognostic value of sex-specific 99th percentiles in high sensitivity cardiac troponin assays for AMI.
The study by Lehmacher et al. reveals comparable diagnostic accuracy between uniform and sex-specific cutoffs, suggesting no clear advantage for the latter.
The results extend this message to uniform cutoffs for hs-cTnI, but the diagnostic accuracy’s reliance on hs-cTnT concentrations is acknowledged as a limitation which requires futher studies before recommending sex-specific cutoffs in clinical practice.
Climate change as a global health problem – are we too late to prevent the consequences?
The EHJ-ACVC joins over 200 heart journals and urges the United Nations, political leaders, and health professionals to address climate change and biodiversity loss together as an indivisible global health emergency.
Recognising the interconnectedness of climate and nature crisis, they emphasise the severe impact on health, from infectious diseases to mental health issues. The call urges the WHO to declare this crisis a global health emergency to be able to restore biodiversity and combat climate change.
