Active clinical trials for "Shock"

Prospective, multi-center, randomized (1:1), controlled trial of Impella for active left ventricular unloading on top of veno-arterial extracorporeal membrane oxygenation vs. veno-arterial extracorporeal membrane oxygenation alone for the treatment of cardiogenic shock.

Mitral regurgitation may be seen in the setting of cardiogenic shock. Transcatheter edge-to-edge repair (TEER) has been shown to improve outcomes in patients with chronic heart failure. Observational studies suggest improvements in clinical outcomes in patients with mitral regurgitation in the setting of cardiogenic shock; however, there remains a lack of randomized clinical data to support the use of TEER in cardiogenic shock. This study will be a multicenter, open-label, randomized-controlled trial with two study arms: medical therapy and TEER. Patients admitted to the Cardiac Intensive Care Unit (CICU), Cardiac Surgery Intensive Care Unit (CSICU) or Intensive Care Units (ICU) at participating centers will be recruited. The study aims to answer the question: "Does TEER in patients with SCAI stage C or D cardiogenic with concomitant moderate or greater mitral regurgitation improve outcomes as compared to medical therapy?" The study hypothesis is that TEER will lead to an overall improvement in the composite outcome as compared to the medical therapy arm.

Prospective, multicenter, randomized, open-label study of standard of care plus the PMX cartridge versus standard of care alone in patients with endotoxemic septic shock

The aim of the study is to demonstrate the superiority of early intra-aortic balloon pump implantation at admission over local clinical practice (pharmacological only) in acute decompensated heart failure patients with cardiogenic shock, with respect to 60-day survival or successful bridge to heart replacement therapies (heart transplant or Left Ventricular Assist Device implantation).

The management of a patient with shock is based on improving tissue oxygenation through hemodynamic optimization. Lactate is a marker of tissue hypoperfusion commonly used in the ICU. In principle, hyperlactatemia can be caused by either increased tissue production (tissue hypoperfusion: type A), decreased lactate uptake (type B), or a combination of both mechanisms. It is important to correctly determine the cause(s) of hyperlactatemia, as this determines the treatment (expanders, inotrope, vasopressor, blood derivative transfusion), and the patient's morbidity and mortality. A classic example of this concept is volume expanders, which are frequently used to correct hyperlactatemia secondary to tissue hypoperfusion, but are associated with mortality if used excessively (fluid overload). In clinical practice, it is difficult to differentiate the exact causes of hyperlactatemia (type A and type B). From work carried out over the last 20 years in septic shock and then in other states of shock and in the operating theatre, it has been shown that the arteriovenous CO2 gradient (pCO2gap) measured from arterial and venous blood gases is a marker of tissue hypoperfusion with better predictive ability than the usual markers (clinical examination, SVO2....). Furthermore, when we relate pCO2gap to the arteriovenous O2 difference (pCO2gap /C(a-v)O2), this ratio allows us to distinguish with greater accuracy between states of acute circulatory failure associated with anaerobiosis (tissue hypoperfusion, type A) and those related to the underlying disease. Also, several studies have demonstrated a strong ability of the pCO2gap and the pCO2gap/CavO2 ratio to predict the severity of shock, mortality of the shock patient, hyperlactatemia, and correction of hyperlactatemia with hemodynamic treatment. As a result, many authors have proposed algorithms for the management of shock patients based on the measurement of these CO2-derived indexes. The hypothesis of this study is that the use of an algorithm based on CO2gap and the CO2gap/CavO2 ratio is superior in terms of correction of hyperlactatemia to usual practice based on clinical and macro-hemodynamics.

This study is a prospective, open-label, two-arm, randomized multicenter trial to identify whether immediate multi-vessel PCI would be better in clinical outcomes compared with culprit lesion-only PCI for AMI and multi-vessel disease with an advanced form of CS patients who require veno-arterial extracorporeal membrane oxygenator (VA-ECMO).

Sepsis is one of the most serious healthcare problems, worldwide, and financial burdens. The overall mortality of severe sepsis/septic shock was 44.5-52.6%. A common cause of death is refractory shock and multi-organ failure. Myocardial dysfunction is a relatively common complication of septic shock. This causes a decrease in the amount of cardiac output, resulting in insufficient blood supply to the organ and multi-organ failure and lead to death Early goal-directed therapy began to use dobutamine in patients with septic shock Sepsis Survival Campaign Guideline 2016 recommended drug is dobutamine and an alternative drug is milrinone in septic shock patients with clinical signs of poor tissue perfusion.

The purpose of this study is to assess whether hemodynamic support with an Impella-based treatment strategy initiated prior to percutaneous coronary intervention (PCI) in patients with ST-Segment Elevation Myocardial Infarction (STEMI)-Cardiogenic Shock (CS) improves survival and functional outcomes compared to a non-Impella-based treatment strategy.
