BIO monitorinG in Patients With Preserved Left ventricUlar Function AfteR Diagnosed Myocardial Infarction

The BIO|GUARD-MI study investigates whether continuous arrhythmia monitoring and the consequent treatment after detected arrhythmias in patients after myocardial infarction with preserved cardiac function, but other risk factors, decreases the risk of major adverse cardiac events.

About this study

Patients randomized to the BioMonitor arm will receive an implantable cardiac monitor (ICM; BioMonitor) with remote monitoring function (Home Monitoring®). If the device detects and reports an arrhythmia, patients will be appropriately examined and treated. Patients randomized to the control arm will receive best proven treatment, but no implantable cardiac monitor.

Primary outcomes

  1. Kaplan-Meier Estimate of Percentage of Participants With Major Adverse Cardiac Event (MACE)

    Time frame: 2 years

    The primary endpoint is defined as death for cardiovascular reasons or unplanned hospitalization for cardiovascular reasons as per study protocol.

    The time period with regards to the Time-to-Event Outcome Measures starts with the randomization of the patient.

    All patients will be assessed for Time-to-Event Outcome Measures until formal study termination is announced or until the individual patient meets a drop out criterion in accordance with the study protocol. The study period is estimated 6 years.

Secondary outcomes

  1. Kaplan-Meier Estimate of Percentage of Participants With Outcome of Death Due to Any Cause

    Time frame: 2 years

    The occurrence of death due to any cause will be recorded and analyzed.

  2. Kaplan-Meier Estimate of Percentage of Participants With Outcome of Death Due to Any Cause or Heart Transplantation

    Time frame: 2 years

    Assessment of the time from randomization to death for any reason or heart transplantation during the clinical investigation.

  3. Kaplan-Meier Estimate of Percentage of Participants With Outcome of Cardiovascular Death or Heart Transplantation

    Time frame: 2 years

    Assessment of the time from randomization to cardiovascular death or heart transplantation during the clinical investigation. A specified endpoint definition will be given by the members of the EAEC and documented in the charter agreement.

  4. Kaplan-Meier Estimate of Percentage of Participants With Worsening of Heart Failure Requiring Hospitalization or Urgent Visit

    Time frame: 2 years

    Assessment of the time from randomization to first hospitalization or urgent visit for worsening of the patient status due to heart failure, or death due to heart failure. A specified endpoint definition will be given by the members of the EAEC and documented in the charter agreement.

  5. Kaplan-Meier Estimate of Percentage of Participants With an Arrhythmia Resulting in Hospitalization

    Time frame: 2 years

    Assessment of the time from randomization to the first hospitalization resulting from an arrhythmia or death resulting from arrhythmia. A specified endpoint definition will be given by the members of the EAEC and documented in the charter agreement.

  6. Kaplan-Meier Estimate of Percentage of Participants With Acute Coronary Syndrome Resulting in Hospitalization

    Time frame: 2 years

    Assessment of the time from randomization to the first hospitalization resulting from acute coronary syndrome or death resulting from acute coronary syndrome. A specified endpoint definition will be given by the members of the EAEC and documented in the charter agreement.

  7. Kaplan-Meier Estimate of Percentage of Participants With Stroke Resulting in Hospitalization

    Time frame: 2 years

    Assessment of the time from randomization to the first hospitalization resulting from stroke or death resulting from stroke. A specified endpoint definition will be given by the members of the EAEC and documented in the charter agreement.

  8. Kaplan-Meier Estimate of Percentage of Participants With Major Bleeding Resulting in Hospitalization

    Time frame: 2 years

    Assessment of the time from randomization to the first hospitalization resulting from major bleeding or death resulting from major bleeding. A specified endpoint definition will be given by the members of the EAEC and documented in the charter agreement.

  9. Kaplan-Meier Estimate of Percentage of Participants With Systemic Embolism Resulting in Hospitalization

    Time frame: 2 years

    Assessment of the time from randomization to the first hospitalization resulting from systemic embolism or death resulting from systemic embolism. A specified endpoint definition will be given by the members of the EAEC and documented in the charter agreement.

  10. Kaplan-Meier Estimate of Percentage of Participants With an Arrhythmia

    Time frame: 2 years

    Assessment of the time from randomization to first arrhythmia.

  11. Type of Initiated Therapies

    Time frame: All data are collected for the period from randomization until official study end or drop-out, for all enrolled patients, up to 6 years.

    Post-hoc categorical summary of most frequent therapies initiated after detection of arrhythmias.

  12. Kaplan-Meier Estimate of Percentage of Participants Receiving Therapy After Arrhythmia Diagnosis

    Time frame: 2 years

    Assessment of the time from randomization to first therapy. In this context therapy is the attempted remediation of the patient's regular heartbeat.

  13. Change in World Health Organization Five Well-being Index (WHO-5) From 6 Months to 24 Months.

    Time frame: We report the intraindividual change from 6-months to 24-months. All data are collected for the period from randomization until official study end or drop-out, for all enrolled patients.

    A further secondary endpoint is the assessment of the patient's well-being. The patient's well-being will be recorded during the regular telephone contacts using the WHO-5 Well-being Index. The scale reaches from 0 (worst status) to 100 (best possible status).

Other outcomes

  1. Mean Value of EQ-5D-5L

    Time frame: From Baseline measurement to 60 months. All data are collected for the period from randomization until official study end or drop-out, for all enrolled patients.

    The EQ-5D-5L questionnaire was administered during the telephone contacts to estimate utility values at different time points for an economic evaluation.

    The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. The scale reaches from 0 (worst status) to 100 (best possible status).
