Active clinical trials for "Shock, Cardiogenic"

The purpose of this study is to better understand the time course of different biological mechanisms involved in acute decompensated heart failure complicated by cardiogenic shock throughout the evaluation of changes and the relationship among markers of inflammation (IL-6) and markers of increased endothelial permeability (Ang-2) or endothelial glycocalyx perturbation (Syndecan-1 and HS) and throughout a targeted metabolomic approach.

The study will provide data on profile, management, outcome, and evolution over time of cardiogenic shock patients admitted to the Intensive Coronary Care Units

This large real-world international prospective registry will provide a unique opportunity to comprehensively understand the contemporary management, clinical course and short as well as long-term outcomes of all Cardiogenic Shock (CS) patients cared for at four high volume dedicated shock care centers. As the first true North American multicenter CS collaborative with a uniform dedicated and comprehensive case report form, the high patient volumes and wide spectrum of clinical acuity seen at these institutions will provide valuable insight into the factors associated with adverse outcomes; and will serve as a blueprint for future clinical trial designs that may better inform clinical practice.

Treatment of refractory cardiac arrest requiring cardiopulmonary resuscitation (CPR) may be augmented with Extracorporeal membrane oxygenation (ECMO) to re-establish perfusion in the absence of return of spontaneous circulation. Literature has demonstrated that ECMO initiated during advanced cardiopulmonary life support may confer superior survival rates with acceptable survival and a relatively low incidence of significant neurologic impairment. Levosimendan has not been investigated in patients with cardiac arrest who underwent Extracorporeal CPR (E-CPR). The current study aims to examine whether levosimendan use in the aforementioned patient population could improve survival and ECMO parameters.

Children supported by Extra-Corporeal Membrane Oxygenation (ECMO) present a high risk of neurological complications and cerebral autoregulation (CA) impairment may be a risk factor. The first objective is to investigate the association between CA impairments and neurological outcome assessed by the onset of an ANE. The secondary objective is to study the underlying mechanisms influencing CA.

VA-ECMO is increasingly utilized in the setting of cardiogenic shock or cardiac arrest to restore hemodynamic stability and end organ function. VA-ECMO serves as a short-term ventricular assist device that can be rapidly placed at the bedside in the emergency room, intensive care unit, cardiac catheterization suite, or operating room. A bridge to decision approach allows for the assessment of neurologic status, renal and hepatic function, and subsequent recovery of cardiac function. Despite its life-saving potential, VA-ECMO is fraught with complications including vascular complications from cannulation. In addition, neurologic injury, renal failure, liver failure, and sepsis are all well described sequelae of the post-cardiogenic shock or cardiac arrest VA-ECMO patient. For these reasons, identifying early prognostic indicators and developing a score with regard to the outcome of this special patient population is of high interest. The proposed study aims to analyze 4 ICU scores/Survival prediction models [APACHE-II (acute physiology and chronic health evaluation II), SAVE (Survival after VA ECMO) , SOFA (sequential organ failure assessment )and CASUS (Cardiac Surgery Score)] and evaluate their performance in predicting survival after VA ECMO insertion. This will be a clinical retrospective study which will be conducted in the Cardiothoracic Intensive Care unit (CTICU) in the Department of Cardiothoracic Surgery, Heart Hospital, Doha. Patients admitted to the CTICU after institution of VA ECMO in the period between 1st January 2015 to 31st October 2022 will be screened retrospectively. Patients who stay for at least 12 hours in the CTICU would be eligible for inclusion in the study. All charts of patients who were admitted to CTICU after institution of VA ECMO during the afore mentioned period will be included in the review. All the risk scores would be calculated separately for all the enrolled patients and then subjected to statistical analysis to determine predictive accuracy for survival.

The study aims to investigate the safety and efficacy of the Synchronized Cardiac Support treatment wit the icor kit and the Xenios console with modified sensor box ECG and Software Version 3.2.4

The primary objective of this study is to assess reasonable safety and performance of the HeartMate PHP to provide hemodynamic support for up to 72 hours in patients with cardiogenic shock requiring stabilization.

Veno-arterial extra-corporeal membrane oxygenation (VA-ECMO) is indicated as a haemodynamic rescue strategy in decompensated acute or chronic heart failure presenting as cardiogenic shock. It has been used across aeitologies including post-myocardial infarction, dilated cardiomyopathy, acute myocarditis and in post-cardiotomy shock. VA ECMO has a number of effects on the circulation including improved end-organ perfusion and possibly improved coronary perfusion, and is a bridge to further therapies including permanent advanced mechanical circulatory support, cardiac transplantation and to cardiac recovery. Left ventricular assist devices (LVADs) provide long-term mechanical circulatory support and also profoundly mechanically unload the left ventricle. Multiple clinical studies have documented cardiac recovery using LVAD therapy, with a rate between 10-60% in selected populations. A large body of basic science has documented the pivotal role of mechanical load in determining ventricular contractile performance across species. Therefore both clinical data and basic laboratory studies support the notion that profound ventricular unloading may result in improved cardiac performance through a variety of mechanisms ranging from triggered de novo cardiomyocyte proliferation, subcellular calcium handling reverse remodeling, changes to the extracellular matrix of the heart, reverse remodeling of the neurohormal milleu, amongst many others. One of the major deficiencies of peripheral VA-ECMO is its lack of left ventricular unloading, with associated pulmonary congestion, which can derail clinical improvement and hamper cardiac recovery. Indeed, percutaneous VA-ECMO increases LV afterload due to the retrograde blood flow, and because of the lack of venting, there may be progressive LV distension. These conditions can result in a congested, pressure-overloaded ventricle, even in the absence of echocardiographic ventricular distension. This may be ameliorated with the addition of ventricular mechanical unloading using percutaneous therapies including the percutaneous left ventricular device, Impella CP. On the platform of VA-ECMO, the addition of an Impella device to reduce ventricular loading results in improved survival and recovery of ventricular performance in the setting of cardiogenic shock. In a number of small studies, the use of additional means to unload the ventricle, principally Impella, results in cardiac recovery and less ventricular distension. In chronic heart failure, direct ventricular unloading is critical to cardiac recovery. The objective of this randomized study is to determine whether the addition of early direct ventricular unloading using Impella CP leads to higher rates of cardiac recovery, defined as survival free from mechanical circulatory support, heart transplantation or inotropic support at thirty days. This study will also examine the clinical, biochemical, echocardiographic and radiologic effects of VA ECMO with and without the addition of Impella CP to directly vent the left ventricle to address adjunct important questions such as the effects on pulmonary congestion.

Tilarginine Acetate Injection is a new type of drug that temporarily stops the body from making a bodily substance called nitric oxide. The body may produce excess nitric oxide following severe heart damage leading to shock. During a heart attack, and especially after a blocked artery causing the heart attack is reopened, a large amount of nitric oxide is released into the heart muscle and into the blood. Normally small amounts of nitric oxide are good for the heart and blood vessels. However, when released in large amounts, such as during a heart attack, it may be harmful, by adding to the damage of the heart attack and lowering the heart's ability to pump blood to the body. It may cause blood pressure to be lowered and reduce the amount of blood flow to the body's vital organs. This may interfere with the body's organs being able to do their work. If Tilarginine Acetate Injection can stop extra nitric oxide from being made, the performance of the heart and blood flow to the organs may get better, which may result in the improvement of symptoms. The purpose of this study (TRIUMPH) is to investigate the safety and effectiveness of Tilarginine Acetate Injection compared to placebo (an inactive fluid that has no effect on the body but looks exactly like the medication being studied). The study will help determine whether Tilarginine Acetate Injection, by temporarily lowering the amount of nitric oxide released into the vital organs can improve blood pressure and the blood flow to the body's organs.
