Cardiogenic Shock

The aim of this observational study is to describe the baseline characteristics, management strategies, and early outcomes (during hospitalisation and at 30 days) of patients admitted to intensive care with cardiogenic shock, regardless of aetiology. This prospective multicenter registry will enroll consecutive patients admitted to participating adult and pediatric critical care units in France, using current definitions and classifications of cardiogenic shock. The study aims to improve patient characterization and risk stratification and support the development of future interventional studies. 1,000 patients will be enrolled over 12 months, with follow-up at 30 days, 1 year, and through linkage with the French National Health Data System (SNDS) at 1 and 5 years.

Cardiogenic shock is a life-threatening condition characterized by inadequate cardiac output, leading to organ hypoperfusion and high mortality. Maintaining mean arterial pressure (MAP) is crucial, but standard targets may be insufficient due to venous congestion. Central venous pressure (CVP) can help assess effective perfusion pressure. This study investigates whether a personalized MAP target adjusted by CVP improves organ function and survival compared to standard MAP management.

CAPITAL OFFLOAD-SHOCK will aim to answer if early use of renal replacement therapy, like dialysis, in patients with reduced body fluids causing the heart to be unable to pump enough blood through the body reduces in-hospital death when compared to the current standard of care. The current standard of care is to wait until renal replacement therapy is clinically necessary.

The goal of this clinical trial is to learn if the drug istaroxime works to treat cardiogenic shock due to acute heart failure in adults. It will also learn about the safety of istaroxime. Researchers will compare istaroxime to a placebo (a look-alike substance that contains no drug) to see if istaroxime works to treat cardiogenic shock due to acute heart failure. The main questions it aims to answer are: * Does istaroxime relieve participants' shortness of breath compared to a placebo? * Does istaroxime provide clinical benefit in terms of lowering the risk of dying, having invasive procedures, being rehospitalized or having worsening heart failure, and/or increasing quality of life compared to a placebo? * Does istaroxime reduce the duration of the initial hospital stay compared with placebo? Participants will: * Receive a 48-hour intravenous infusion of istaroxime or placebo with possible additional retreatment depending on their clinical condition * Complete questionnaires rating their breathing and describing their quality of life * Return for visits 30 and 90 days after the start of Cycle 1 infusion. The trial will end when the last participant completes Day 30 and all participants have been followed for at least 30 days after their last IMP exposure. At trial termination, participants who have not been followed to Day 90 will have an end-of-study (EOS) visit.

NUROPI is a single-centre, prospective, non-interventional study in the Intensive Care Unit (ICU) of Erasme Hospital (Hôpital Universitaire de Bruxelles, Brussels, Belgium). Some critically ill patients get worse during the first days of their ICU stay. Identifying them early could allow faster escalation of care. Nucleosomes are fragments of DNA wrapped around proteins called histones. They are released into the blood when cells die or when white blood cells form neutrophil extracellular traps (NETs). High blood levels of nucleosomes may reflect inflammation, clotting activation and organ damage. This study will measure the H3.1 nucleosome in the blood of 1,000 consecutive adult ICU patients. The measurement uses a CE-marked laboratory test (Nu.Q® NETs, chemiluminescence immunoassay on the IDS-i10 analyser). No additional blood sample is taken for the study. H3.1 is measured on the leftover plasma of blood samples already drawn for routine care, at ICU admission, 6 hours, day 1, day 3 and day 7. Patient treatment is not changed. Patients, or their relatives or legal representative, receive an information notice and may refuse participation at any time. The main question is whether H3.1, alone or combined with routine ICU data, can identify patients at high risk of clinical deterioration within 72 hours of ICU admission. Other questions concern the link between H3.1 and mortality, organ dysfunction, and ICU treatments, and how H3.1 levels change during the first week.

This multicenter randomized controlled trial compare two transfusion strategies of red blood cells transfusion in patients supported by veno-arterial extracorporeal membrane oxygenation for refractory cardiogenic shock. An individualized transfusion strategy based on ScVO2 level, is compared to a conventionnal strategy based on predefined hemoglobin threshold. The primary endpoint is the consumption of packed red blod cells, secondary endpoints are subgroup analysis, mortality, morbidity, and cost-effectiveness

Acute myocardial infarction complicated by cardiogenic shock (AMI-CS) is a severe condition with high mortality. Early revascularization and Impella device (Abiomed) support improve outcomes. Observational studies like the National Cardiogenic Shock Initiative (NCSI), Inova-Shock registry, and J-PVAD (Japan registry for percutaneous ventricular assist device) registry emphasize the importance of structured care systems when using mechanical circulatory support (MCS). Following the release of the Danger Shock trial, MCS use is expected to rise. Hospitals will need to monitor practices and work with payers to ensure coverage. Using regional real-world data can assist this process, making the collection and analysis of MCS outcomes essential. The NCSI (NCT03677180) aimed to evaluate outcomes with a protocolized approach prioritizing rapid diagnosis, timely MCS delivery, and invasive hemodynamic monitoring via pulmonary artery (PA) catheters. The study involved 406 patients from 2016 to 2020, with an average age of 64 years. Most (67%) had shock, with 85% on vasoactive drugs. Witnessed outof-hospital cardiac arrest occurred in 17%, and in-hospital arrest in 30%. During MCS implantation, 9% were actively resuscitating. Patients mostly in SCAI stage C/D (73%) and stage E (27%) presented with low blood pressure, high lactate, and reduced cardiac power output. About 70% received MCS before PCI, with 90% using PA catheters. Most had STEMI, with median door-to-support and door-to-balloon times of about 78 and 81 minutes. Survival rates were high: 99% procedural, 79% to discharge, 77% at 30 days, and 62% at one year for stage C/D shock. Patients with stage E shock had lower survival. Early use of MCS improved hemodynamics and survival. Further research, like the CERAMICS (Can Escalation Reduce Acute Myocardial Infarction in Cardiogenic Shock) study, aims to refine escalation strategies. The Danger Shock trial highlighted the importance of minimizing complications such as bleeding, limb ischemia, haemolysis, and kidney injury. Currently in Hong Kong, prevalence of CS among AMI patients is 5-10%, in-line with global statistics. Among which, 30-day and 1-year mortality of AMI-CS patients in Hong Kong was reported at 29% and 39.5% respectively. Although the use of MCS has been shown in the above overseas studies to improved survival rates of AMI-CS patients, the utilisation rate of MCS among AMI-CS patients in Hong Kong was reported at 36.5% in a previous single-centre study, limited by an array of factors including limited device availability, allocations of resources and patient selection strategy, lack of region-specific evidence and device affordability. Global Cardiogenic Shock Initiative (GCSI) is an ongoing international multicenter registry involving centers from USA, Germany, and Hong Kong, and focus on the outcomes of AMI-CS patients received Impella support. The GCSI is expanding to many other regions. In the Hong Kong Cardiogenic Shock Initiative (HK-CGSI) study we aim to include sites with experience in MCS, all of whom have the capability of MCS escalation and evaluate outcomes across these centers. The goal is not only to capture the effects of previously established best practices but gain insights into regional best practices, and together with data from the global cardiogenic shock initiative (GCSI), to better establish the adoption of novel best practices and their effect on complication rates. In parallel to GCSI-eligible cohort, i.e. Impella used as the first supporting device for patients with AMI-CS, given the significant portion of patients who could not receive MCS under current limitations in Hong Kong, in the HK-CSI, we will include also the GCSI-ineligible cohort, i.e. AMI-CSI without using Impella or not as the first MCS used, to understand the full picture of clinical outcomes of AMI-CS patients of Hong Kong. The HK-CSI study is an observational registry solely and not a treatment study. This single-arm registry captures data generated during procedures which are considered standard of care. Participation in this registry will be performed with waiver of consent of the patient and will have no influence on the type and extent of treatment.

This is a prospective, single-center, observational pilot study of the investigational NIRSense Tissue Oximetry Sensor System (Envello Core), a noninvasive wearable sensor patch that uses near-infrared spectroscopy (NIRS) and photoplethysmography (PPG), combined with an electrocardiography/impedance cardiography (ECG/ICG) sensor, to continuously monitor tissue oxygen saturation (StO2), peripheral oxygen saturation (SpO2), pulse rate, respiratory rate, stroke volume, and related metrics. Up to 20 adults admitted to the Cleveland Clinic Florida cardiac intensive care unit with acute myocardial infarction or acute decompensated heart failure and in Society for Cardiovascular Angiography and Interventions (SCAI) shock stage B, C, or D will wear the sensors on the sternum, forearm, and other locations for approximately 24 to 72 hours during standard care. Sensor data will be compared with standard-of-care hemodynamic and laboratory measurements and with the patient's clinical course to evaluate the feasibility of the device, the correlation of its measurements with established clinical parameters, and its potential to detect deterioration in SCAI shock stage earlier. No treatment decisions are made based on the study device.

PRIME-SHOCK is a prospective, single-center, open-label, randomized, superiority trial. Eligible participants with AMICS and a clinical decision to use Impella CP will be randomized in a 1:1 ratio before culprit-lesion PCI. The routine pre-PCI group will undergo Impella CP insertion immediately after allocation and before culprit-lesion PCI. The selective post-PCI group will undergo culprit-lesion PCI first; Impella CP will be inserted only if prespecified intra-procedural rescue criteria are met or shock persists or worsens after successful PCI. If all post-PCI recovery criteria are met, PCI will be concluded without Impella CP.

The study will evaluate the impact of a combined device-drug strategy with Impella 5.5 with best practices and optimized GDMT on heart recovery outcomes in patients with decompensated heart failure and cardiogenic shock.

This is a prospective and retrospective multicentre study conducted under the scientific coordination of the IRCCS Fondazione Don Gnocchi and funded by the Italian Ministry of Health (PNRR-MCNT2-2023-12377767). Using the Altshock registry, the largest multicentre Cardiogenic Shock (CS) registry in Italy, which currently has registered more than 1,000 CS patients across Italy, we will recruit patients to: (1) provide a granular assessment of post-acute phase programmes, patients' functional disability, return to work and quality of life, including specific reference to gender; (2) implement specific pathways of care in the post-acute phase; (3) provide a multidimensional assessment, thus validating an innovative model in comparison with the traditional pathway, defining the potential benefits to and impact on economic efficiency and the general sustainability of this therapeutic trajectory.

This study is a prospective, multicenter, single-arm clinical trial conducted in China to evaluate the efficacy and safety of a novel left ventricular assist device, SynFlow Duro system, manufactured by ForQaly Medical in the treatment of post cardiotomy cardiogenic shock.

Cardiogenic shock is the most severe manifestation of acute heart failure and remains the leading cause of death in patients hospitalised with acute myocardial infarction. Cardiogenic shock is a well-known and potent trigger of the immune response, ischemia/reperfusion organ damage, hemolysis and release of free hemoglobin. The activation of immune cells leads to the release of cytokines and inflammatory mediators such as IL-6, IL-8, activated complement and others. As a result of myocardial ischaemia and reperfusion injury, a multiorgan dysfunction syndrome may develop. The Efferon CT hemoadsorption device effectively removes cytokines and other pro-inflammatory molecules (≤55 kDa). This study evaluates whether this blood-filtering therapy can prevent organ failure in acute myocardial infarction patients with cardiogenic shock by eliminating inflammation-inducing mediators.

The goal of this clinical trial is to learn which treatment strategies improve survival in adult patients with acute myocardial infarction complicated by cardiogenic shock (AMI-CS). The main questions it aims to answer are: * Does the immediate use of a left-sided microaxial flow pump (Impella) after percutaneous coronary intervention (PCI) improve survival compared to initial medical therapy alone? * Does protocol-based hemodynamic monitoring and optimization using a pulmonary artery catheter (PAC) improve survival compared to conventional intensive care monitoring? Researchers will compare four treatment combinations to see if mechanical circulatory support and/or advanced hemodynamic monitoring reduce mortality in AMI-CS patients: * Microaxial flow pump + pulmonary artery catheter * Microaxial flow pump + conventional monitoring * Medical therapy alone + pulmonary artery catheter * Medical therapy alone + conventional monitoring Participants will: * Undergo immediate coronary angiography and PCI upon hospital admission Be randomly assigned to one of four treatment groups * Receive either immediate implantation of a microaxial flow pump or initial medical therapy with vasoactive agents following PCI * Be monitored either via pulmonary artery catheter with protocol-based hemodynamic optimization or via conventional intensive care monitoring * Be followed up at 30 days, 6 months and 12 monthsafter Randomization, with planned annual follow-up assessments for up to 10 years

Despite advancements in treatment, the mortality rate for cardiogenic shock (CS) remains high at around 50%. The EMPULSE-HF trial showed that early introduction of empagliflozin in stabilized patients with acute heart failure led to a composite benefit in mortality, rehospitalization, and quality of life. Growing evidence suggests that cardiogenic shock isn't just a problem of systemic macrocirculation (blood pressure, cardiac output). It also involves significant abnormalities in the systemic microcirculation. In fact, these microcirculatory parameters have proven to be better predictors of patient outcomes than traditional macrocirculatory measures. Given its known vasculo-protective effects on the endothelium, empagliflozin may have a beneficial impact on the microcirculation, potentially explaining its positive effects in cardiogenic shock. This study will explore this hypothesis by analyzing the microcirculation in real-time using the CytoCam-IDF imaging videomicroscope and its MicroTools software. The goal is to gain a deeper understanding of how empagliflozin affects the microcirculation during cardiogenic shock.

Study Title: Safety and Efficacy of Extracorporeal Ventricular Assist System for Cardiogenic Shock: A Prospective, Multicenter, Single-Arm Clinical Study Objective: To evaluate the safety and efficacy of temporary mechanical circulatory support and bridge therapy with an extracorporeal ventricular assist system in patients with cardiogenic shock or weaning failure from cardiopulmonary bypass, and to comprehensively assess the device, pump head, cannulae and tubing. Pilot Phase: Clinical validation of Class III medical device. Study Design: Prospective, multicenter, single-arm target-value design. Sample Size: 40 patients. Primary Endpoint: Success rate of mechanical circulatory support. Secondary Endpoints: 30-day survival after transition to long-term therapy (VAD/transplant); 30-day cardiovascular mortality after device explantation; MACCE incidence; Mean support duration; Incidence of bleeding, thrombosis, hematologic events, acute renal/hepatic dysfunction, infection; Hemodynamic trends during support; Changes in SCr, BUN, ALT, TBIL at use, discharge and 30 days post-explantation vs baseline; Device satisfaction. Follow-up: Within 6 hours of initiation, during support, 24 hours, 7 days, 30 days post-explantation/transition, and at discharge. All clinical data were collected, managed and analyzed by an independent data and statistical center and clinical monitoring unit to support safety/efficacy evaluation and market approval.

This pilot study investigates whether giving a short course of intravenous corticosteroids (methylprednisolone) alongside standard medical care can help patients recovering from heart failure-related cardiogenic shock. Heart failure-related cardiogenic shock happens when chronic heart dysfunction causes poor blood circulation and congestion throughout the body. Often, this condition triggers severe inflammation, making it harder for the heart and other organs to recover, even when temporary mechanical heart pumps are used to support blood flow. The study aims to see if reducing this inflammation with corticosteroids is safe and can help patients get better faster. Researchers will enroll 30 adult patients hospitalized with early-stage (SCAI Stage B or C) cardiogenic shock related to heart failure. To participate, patients must also show high levels of inflammation in their blood, specifically a high-sensitivity C-reactive protein (hsCRP) level of 20 mg/L or higher Participants will be randomly assigned by chance to one of two groups. One group will receive the standard of care alone. The other group will receive the standard of care plus a 7-day course of intravenous methylprednisolone. The main goal of the study is to measure the change in inflammation levels (hsCRP) over 7 days. Researchers will also monitor how well the patients' organs recover, track their need for blood pressure medications or mechanical heart pumps, and monitor for any side effects to ensure the treatment is safe

Cardiac disease complicated by respiratory insufficiency comprises the most frequent indication for cardiac intensive care unit (CICU) admission, with nearly one-third patients requiring advanced respiratory support and over 20% patients requiring invasive mechanical ventilation (IMV). IMV among patients with impaired cardiovascular reserve is further compounded by the adverse impact of positive pressure ventilation (PPV) and systemic sedation on intracardiac hemodynamics, pulmonary vascular mechanics and consequently end-organ perfusion. Despite widespread use, evidence guiding optimal ventilatory practices and mode selection in cardiovascular intensive care unit patients remains limited. Pressure-controlled and volume-controlled ventilation may differ in their effects on patient-ventilator synchrony, sedation requirements, and hemodynamic impact, but comparative data among patients with critical cardiac disease remains inconclusive. This pilot study will evaluate the feasibility of implementing a pragmatic cluster-randomized crossover trial comparing ventilatory modes in a contemporary cardiovascular intensive care unit.

There are two primary goals of this multicenter clinical trial that combines an FDA device trial and a phase II drug trial in the same study cohort. These two goals are to: 1. To evaluate the safety and effectiveness of the Cardiohelp Device for VA-ECMO (heart-lung support) for up to 30 days of support in children with severe heart failure with the goal to support its FDA clearance in children. 2. To evaluate heparin versus bivalirudin as the primary blood thinner (anticoagulant) in a randomized trial of children supported with the Cardiohelp ECMO System with the goal to plan a phase III (pivotal) randomized clinical trial The main questions the Cardiohelp single-arm trial seeks to answer are: * What is the safety and effectiveness of the Cardiohelp device for pediatric ECMO? * Should the Cardiohelp device be FDA-cleared for children based on the results of the study? * What are the optimal performance specifications of the Cardiohelp device in children? The main questions the blood thinner randomized trial seeks to answer are: * Which blood thinner is more promising (i.e., more effective and safer) in children on the Cardiohelp device? * How should a pivotal trial of heparin vs. bivalirudin be designed so it is the most informative and efficient to determine the best blood thinner? Children who are receiving the Cardiohelp device will be approached and consented to participate if interested. For the Cardiohelp device trial, participants will undergo a standardized data collection to estimate survival to 30 days and the prevalence of serious adverse events like stroke, bleeding, and hemolysis. For the blood thinner randomized trial, participants will be randomized 1:1 to blood thinner strategy to determine which blood thinner has the fewest bleeding and clotting complications. For the Cardiohelp single-arm trial, participant outcomes will be compared to performance goals (PG) derived from the ECMO literature. For the blood thinner randomized trial, the amount of bleeding and clotting will be measured. The study is funded by an R01 grant from the FDA's Office of Orphan Product Development (OOPD).

The main purpose of this study is to determine whether differences in myocardial reserve predict clinical outcomes for heart failure patients.

The goal of this observational study is to learn whether information collected during routine hospital care, together with blood and urine samples, can help doctors better identify different types of cardiogenic shock and better predict outcomes in adults hospitalized with acute heart failure and cardiogenic shock. The main question is whether clinical findings, imaging results, and biomarkers, including sex-specific factors, are associated with the risk of death within 30 days. Participants will not receive an experimental treatment. Researchers will collect data from routine care, collect additional blood and urine samples for biobanking, and follow participants after hospital discharge

The Elevate™ CS Clinical Feasibility Study is designed to evaluate the initial safety, effectiveness, and device performance of the Magenta Elevate™ System in patients with cardiogenic shock due to isolated or predominant left ventricular failure.

Cardiogenic shock complicating acute myocardial infarction remains associated with high short-term mortality despite guideline-directed therapy. Systemic inflammation, particularly elevated C-reactive protein (CRP), may contribute to ongoing myocardial injury and organ dysfunction. The CRP-SHOCK trial is an investigator-initiated, prospective, randomized, open-label, multicenter pilot study evaluating selective CRP apheresis as an adjunct to standard of care in patients with infarct-related cardiogenic shock. Patients are randomized to receive either standard therapy alone or standard therapy plus selective CRP apheresis using the PentraSorb®-CRP system. The primary objective is to assess the effect of CRP apheresis on the CLIP score at 66 ± 8 hours after randomization. Secondary objectives include clinical outcomes, inflammatory biomarkers, and safety endpoints.
