Observational Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07825363). This is a study registration, not published results. Lead sponsor: NIRSense Inc.. Recruitment status: RECRUITING. Study type: OBSERVATIONAL. Enrollment: 20 participants (ESTIMATED). Conditions: Cardiogenic Shock, Acute Myocardial Infarction, Acute Decompensated Heart Failure. Interventions: DEVICE: NIRSense Tissue Oximetry Sensor System. Primary outcome measures: Correlation between NIRSense sensor measurements and standard-of-care hemodynamic parameters , Continuous monitoring during the cardiac ICU stay, approximately 24 to 72 hours from sensor application. Brief summary: 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.
