Study summary

This study aims to evaluate the accuracy, feasibility, and clinical usefulness of a wearable ultrasound imaging system for cardiac monitoring during perioperative care and in intensive care units (ICUs).

Traditional bedside echocardiography provides important information about heart structure and function but is usually performed intermittently. Wearable ultrasound technology may allow more frequent monitoring of cardiac function and help healthcare professionals recognize changes in patients' conditions.

This prospective device-comparison study plans to enroll 600 patients, including 400 adults and 200 children, receiving care in cardiac intensive care settings at Fuwai Hospital.

Participants will undergo cardiac monitoring using a wearable ultrasound imaging system in addition to conventional bedside echocardiography. The wearable device will obtain cardiac ultrasound images that can be transmitted wirelessly for remote assessment by physicians. Under stable clinical conditions, ultrasound assessments will generally be performed hourly, with additional assessments when significant circulatory changes occur. Conventional bedside echocardiography will be performed daily for comparison.

The study will compare measurements of cardiac structure and function obtained using the two methods, including left ventricular ejection fraction (LVEF), and evaluate their agreement and ability to identify clinically important cardiovascular changes.

In a subgroup of 400 participants (300 adults and 100 children), wearable ultrasound images will also be displayed alongside electrocardiography, blood pressure, and oxygen saturation measurements on bedside monitors to evaluate the feasibility and potential clinical benefits of integrated monitoring.

The findings may help determine whether wearable ultrasound technology can provide accurate and practical cardiac monitoring for critically ill patients.

Inclusion criteria

  • Patients of any age, including neonates, receiving care in the adult intensive care unit (ICU), coronary care unit (CCU), or pediatric intensive care unit (PICU) at Fuwai Hospital. There are no minimum or maximum age restrictions.
  • Patients with severe cardiovascular conditions requiring perioperative cardiac or cardiopulmonary intensive care.
  • Written informed consent provided by the patient or the patient's parent or legal guardian.

Exclusion criteria

Exclusion Criteria:

  • Unable to cooperate with or complete the wearable echocardiography examination.
  • Poor transthoracic echocardiographic image quality that prevents acquisition of standard cardiac views.
  • Severe wound infection that prevents placement of the wearable ultrasound device.
  • Delayed sternal closure that prevents placement of the wearable ultrasound device.
  • Patient or parent or legal guardian declines participation in the study.

    Wearable Ultrasound Monitoring

    All participants will undergo cardiac monitoring using a wearable ultrasound imaging system in addition to conventional bedside echocardiography. Wearable ultrasound assessments will generally be performed hourly under stable clinical conditions and additionally when significant circulatory changes occur. Conventional bedside echocardiography will be performed daily for comparison. A subgroup of 400 participants will also undergo integrated monitoring combining wearable ultrasound with electrocardiography, blood pressure, and oxygen saturation measurements.

    Device: Wearable Ultrasound Imaging System

Interventions

  • DeviceWearable Ultrasound Imaging System

    A wearable ultrasound transducer will be positioned on the chest by an experienced sonographer to obtain cardiac images, primarily the apical four-chamber view. Images will be transmitted wirelessly for remote review. Two-dimensional, color Doppler, spectral Doppler, and M-mode imaging will be used to assess cardiac structure and function, including left ventricular ejection fraction (LVEF). Ultrasound assessments will generally be performed hourly under stable clinical conditions and additionally when significant circulatory changes occur. All participants will also undergo routine daily bedside echocardiography for comparison. In a subgroup of 400 participants (300 adults and 100 children), wearable ultrasound images will be displayed alongside electrocardiography, blood pressure, and oxygen saturation measurements on bedside monitors.

What researchers measure

Primary outcomes

  1. Agreement in Left Ventricular Ejection Fraction Measurements

    Agreement between left ventricular ejection fraction (LVEF) measurements obtained using wearable ultrasound and conventional bedside echocardiography will be assessed using the intraclass correlation coefficient (ICC). Paired measurements will be used to evaluate the consistency of the two methods.

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Nov 2026; primary completion for Dec 2028, 25 months later.

Of 1,032 non-industry interventional studies with no phase under Cardiovascular Diseases, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 48. This study's planned 25 months is close to that.

Counting every sponsor, half of 1,148 studies reached it within 26 months; a quarter within 13 and three quarters within 49.

Cardiovascular Diseases covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
