BIOTRONIK Announces First Enrollments in the BIO|GUARD-MI Study
Study Evaluates Whether Early Detection of Cardiac Arrhythmias by BioMonitor with Home Monitoring Reduces Major Cardiovascular Events in Post Acute Myocardial Infarction Patients
BioMonitor is a unique and leadless cardiac monitor implanted under the skin and intended to track cardiac electric activity and provide long-term remote monitoring of patients with arrhythmias. It uses BIOTRONIK Home Monitoring® for the automatic daily transmission of information on both the patient's clinical and device status.
"From previous study results, we already know just how important cardiac arrhythmia can be as an indicator of further critical events in heart patients," commented coordinating clinical investigator Christian Jons, Rigshospitalet Heart Center, Copenhagen, Denmark. "The question now, which we hope to address with the BIO|GUARD-MI study, is whether highly accurate and reliable monitoring tools like BioMonitor with Home Monitoring, can help us identify early warning signs, thereby leading to faster treatment while minimizing direct interference in patients' lives."
A previous study2 indicated that a cardiac arrhythmia is the most powerful predictor for a MACE in post-AMI patients who have a left ventricular ejection fraction (LVEF) ≤ 40%. Of these patients, 20% experienced a major cardiovascular event within two years. From those, more than 80% were diagnosed with a cardiac arrhythmia before the event, by using an implantable cardiac monitor. However, the patient group with a relatively preserved ejection fraction after AMI is quite large, but until now underrepresented in clinical studies. 80 to 90% of patients who survive AMI have relatively preserved ejection fraction with LVEF > 35%. BIO|GUARD-MI will now look at whether these patients receive similar benefits from using BioMonitor, as patients with lower LVEF.
"Studies such as IN-TIME3, COMPAS4 and TRUST5 have demonstrated that BIOTRONIK Home Monitoring greatly improves clinical outcomes for pacemaker, ICD and CRT patients," added Klaus Contzen, Director Clinical Affairs at BIOTRONIK. "We expect BIO|GUARD-MI to demonstrate a clinical benefit for post AMI patients who don't have a pacemaker or ICD indication yet as well, thus proving BioMonitor's benefits for a broad range of patient populations. Thanks to the combination of BioMonitor and Home Monitoring, we are now able to assess this underexplored patient population for the first time."
The prospective, controlled, randomized, multicenter trial will enroll 2,900 patients in approximately 35 centers worldwide. The primary endpoint is the time from randomization to the first MACE.

* Several severe cardiovascular complications can be classified under the term MACE, such as: cardiovascular death, acute unscheduled hospitalization due to: worsening of the patient status due to heart failure, arrhythmia, acute coronary syndrome, stroke, major bleeding, systemic embolism.
