MyokinE100 System: Closed Loop Electrical Muscle Stimulation to Mitigate ICU Acquired Weakness in Medical ICU Patients

The goal of this clinical trial is to learn if a new medical device that sends electrical signals to the thigh muscles is safe and easy to use for people in the ICU (Intensive Care Unit) who are at risk of losing muscle strength. It will also explore whether this treatment can help slow down muscle weakening. The main questions this study aims to answer are: * Do participants develop medical problems when receiving electrical muscle stimulation in the ICU? * Is electrical muscle stimulation a practical way to help reduce muscle weakness in critically ill patients? Researchers will compare the control group (standard of care) to the intervention group (standard of care plus 60-minute sessions of electrical muscle stimulation daily during the ICU stay) to see if the device is safe and easy to use. Participants will: * Receive either standard of care or standard of care plus electrical muscle stimulation of the thigh muscles * Have their muscle strength checked during the study * Complete a survey three months after ICU discharge to check on their recovery

Intensive Care Unit-acquired Heart Failure in Critically Ill: the ICU-HF Study

Critically ill patients in intensive care units (ICUs) are exposed to a wide range of complications that can affect long-term morbidity and mortality. Not only the initial diagnosis at the time of admission may lead to complications; the ICU stay itself can also be associated with specific disease patterns. One of the most frequent complications of intensive care treatment is the loss of skeletal muscle mass. Muscle atrophy can be detected in up to 17% of all critically ill ICU patients. This is accompanied by a neuromuscular organ dysfunction collectively referred to as Intensive Care Unit Acquired Weakness (ICUAW). Milder forms of ICUAW are present in up to 40% of all ICU patients, which corresponds to approximately 1.2 million individuals per year in Germany alone. These patients face a multitude of long-term complications and have an increased mortality risk that may persist for up to five years after ICU discharge. To date, the definition of ICUAW is limited to the skeletal musculature of critically ill patients. It remains unclear whether an ICU stay also affects other muscle groups, such as the myocardium. A first retrospective study demonstrated a significant reduction in cardiac muscle mass in critically ill ICU patients. However, the clinical implications of this loss of myocardial mass and the contributing factors remain uncertain. In addition, the patient cohort was highly heterogeneous regarding the initial diagnosis, the intensive care therapies performed (e.g., invasive ventilation), and the findings were based on a small sample size of just 44 patients. Another study investigated the association between skeletal muscle atrophy and myocardial structure in a cohort of 378 community-dwelling older adults. They showed that a decrease in skeletal muscle mass was also accompanied by a reduction in myocardial mass. Furthermore, they found a correlation between skeletal muscle atrophy and reductions in left ventricular and left atrial dimensions. However, it remains unclear whether a reduction in myocardial mass is associated with heart failure. Heart failure is associated with a significantly increased risk of long-term morbidity and mortality. The diagnosis and staging of heart failure is primarily based on morphological assessment via transthoracic echocardiography (TTE), in combination with laboratory biomarkers (e.g., NT-proBNP), and the patient's subjective functional impairment as classified by the New York Heart Association (NYHA). Identifying heart failure is clinically relevant, as optimized pharmacologic therapy can lead to significant improvements in cardiac function and positively impact long-term survival. The aim of this study is to investigate the impact of intensive care treatment on myocardial mass and to assess a potential correlation with heart failure. Measurement of myocardial mass and evaluation of heart failure will be performed via transthoracic echocardiography.
