NCT07622485

Brief Summary

Patients hospitalized with cardiovascular disease require timely detection of clinical deterioration to prevent adverse outcomes. Standard inpatient care relies on intermittent nursing vital-sign measurements performed every 4 to 8 hours, which can miss hemodynamic or arrhythmic events occurring between measurements. This trial evaluates whether digital wearable-based monitoring - wireless continuous measurement of vital signs and electrocardiography with a real-time alerting system - reduces major adverse cardiovascular events (MACE) compared with standard intermittent monitoring in patients hospitalized for cardiovascular disease. The trial uses a stepped-wedge cluster-randomized design in which four inpatient ward zones (clusters) are sequentially transitioned from standard care to wearable monitoring over five periods.

Outcome Measures

Primary Outcomes (1)

  • Composite incidence of major adverse cardiovascular events (MACE)

    Composite of cardiovascular death, myocardial infarction, stroke, unplanned revascularization (PCI or CABG), and cardiovascular rehospitalization, adjudicated by a blinded endpoint adjudication committee.

    Within 6 months after admission

Secondary Outcomes (12)

  • In-hospital cardiac arrest

    Through hospital discharge, up to 30 days

  • ICU transfer rate

    Through hospital discharge, up to 30 days

  • Length of hospital stay

    Through hospital discharge, up to 30 days

  • Accuracy of wearable vital-sign measurement

    Through hospital discharge, up to 30 days

  • Arrhythmia detection performance

    Through hospital discharge, up to 30 days

  • +7 more secondary outcomes

Study Arms (2)

Wearable-based monitoring (intervention)

EXPERIMENTAL

During periods in which the patient's cluster operates in the intervention state, patients receive continuous wearable monitoring using the thynC Inpatient Monitoring System with a real-time alerting system, in addition to standard care.

Device: thynC Inpatient Monitoring System

Standard care (control)

NO INTERVENTION

During periods in which the patient's cluster operates in the control state, patients receive standard care, including intermittent nursing vital-sign measurement every 4 to 8 hours.

Interventions

A wearable continuous monitoring system comprising an ECG patch, a temperature patch, and a pulse oximeter that wirelessly transmit continuous vital-sign and electrocardiographic data to a central monitoring system with automated two-tier (Red/Yellow) alerts. Worn from admission until discharge.

Eligibility Criteria

Age20 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults aged 20 years or older
  • Hospitalized for cardiovascular disease, with at least one of: acute coronary syndrome; chronic coronary syndrome; acute heart failure (NYHA class III-IV or acute decompensated heart failure); arrhythmia (atrial fibrillation, ventricular tachycardia, complete AV block, or other clinically significant arrhythmia); peripheral arterial or aortic disease; post-cardiovascular-procedure observation (PCI, CABG, valve surgery, or electrophysiology study); or thromboembolic disease
  • Able to provide written informed consent
  • Able to wear the wearable monitoring device

You may not qualify if:

  • Hemodynamically unstable shock (sustained systolic blood pressure \< 90 mmHg requiring vasopressors; cardiogenic shock; septic shock)
  • Planned or current intensive care unit admission
  • Within 24 hours after cardiopulmonary resuscitation
  • Physical condition precluding device wearing (bilateral upper-limb amputation; severe skin lesion, burn, or open wound at the device site; known allergy to device materials)
  • Severe cognitive impairment or delirium precluding informed consent Extracorporeal membrane oxygenation (ECMO) or intra-aortic balloon pump (IABP) in use
  • Continuous renal replacement therapy (CRRT) in use (patients on CRRT may participate if hemodynamically stable and device wearing is technically feasible)
  • Unable to communicate in Korean for study explanation and the consent process
  • Previously enrolled in this study (re-admitted patients are not re-enrolled; each participant is enrolled only at the first admission)
  • Considered inappropriate for participation by the investigator
