Heart surgery recovery gets a wireless watchdog
NCT ID NCT07736066
First seen Jul 30, 2026 · Last updated Jul 31, 2026 · Updated 1 time
Summary
This trial tests whether a wearable ECG patch can help people recover better after heart surgery. Participants wear the MEMO Patch, which continuously records heart signals and activity, while completing a cardiac rehabilitation program that starts in the hospital and continues at home. Researchers will measure changes in exercise capacity, muscle strength, and quality of life to see if remote monitoring improves outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a wearable adhesive ECG monitoring device called MEMO Patch, plus a Phase I cardiac rehabilitation program
- What this could lead to
- If it works, this could make cardiac rehabilitation safer and more effective by allowing doctors to monitor patients remotely after heart surgery.
- What could go wrong
- This is a small, single-arm study with only 22 participants, so results may not apply to all heart surgery patients. The device may cause skin irritation or discomfort.

Inclusion Criteria: * Adults aged 19 years or older * Patients diagnosed with cardiovascular disease (e.g., acute coronary syndrome, heart failure, or valvular heart disease) who have undergone cardiac surgery * Low- or intermediate-risk patients with a left ventricular ejection fraction (LVEF) of 35% or greater on echocardiography * Patients with sufficient cognitive ability to understand the cardiac rehabilitation program using a mobile device, application, and the MEMO Patch * Patients who were independently ambulatory prior to surgery * Patients capable of undergoing an exercise stress test * Patients who voluntarily provide written informed consent to participate in the study Exclusion Criteria: * High-risk patients (e.g., patients with aortic dissection, survivors of cardiac arrest or sudden cardiac death, or patients with an implantable cardioverter-defibrillator) * Patients with uncontrolled medical diseases * Patients who are unable to walk independently * Patients with contractures of the hip, knee, or ankle joints that interfere with walking * Patients with musculoskeletal or neurological disorders affecting the lower extremities * Patients with physical conditions that preclude high-intensity gait training * Patients receiving other treatments that may affect the safety or efficacy assessments * Patients who do not provide written informed consent to participate in this clinical study
