Orange County Heart Institute & Research Center Announces FDA Approval

of World’s First and Only Implantable Cardiac Monitor and Patient Alerting System for Acute Coronary Syndromes (ACS) after its

Participation in the ALERTS Clinical Study

The ‘AngelMed Guardian System’ Designed to Warn

High Risk Patients of Potential ACS (MI or Unstable Angina)

ORANGE COUNTY HEART INSTITUTE & RESEARCH CENTER, ORANGE CA, May 11, 2018 - Dr. Kelly Tucker of Orange County Heart Institute & Research Center announces that the ‘AngelMed Guardian® System’. has received U.S. Food and Drug Administration (FDA) premarket approval (PMA).

The AngelMed Guardian System is an implantable cardiac monitor with patient alerting capability and an additional external alarm device. It is indicated for use in patients who have had prior ACS events including myocardial infarctions (heart attacks) or unstable angina and who remain at high risk for recurrent ACS events. The Guardian System is an adjunct to patient recognized symptoms by detecting potential ongoing ACS events, characterized by sustained ST segment changes, and alerting the patient to seek medical attention for those events.

Approval of the ‘AngelMed Guardian System’ by the U.S. FDA was based on preclinical and clinical data, including data derived from the ALERTS Clinical Study that began in 2009. Orange County Heart Institute & Research Center was among the one hundred centers across the U.S. that participated in the ALERTS Clinical Study, with 910 patients implanted. The ALERTS Clinical Study concluded in 2015 after accumulating 3,450 implant years of follow-up data.

"The AngelMed system represents a huge move forward in medical technology and allows physicians now for the first time to detect silent events. This is going to save hundreds of thousands of lives each year. It's a wonderful device." said Orange County Heart Institute & Research Center Electrophysiologist, Dr. Kelly J. Tucker.

“We are so thankful to Dr. Kelly J. Tucker, Principle Investigator and Karena De La Mora, Research Coordinator at Orange County Heart Institute & Research Center for all of their efforts during the ALERTS Clinical Study. Without their dedication and hard work, we would never have reached approval. We will also be forever thankful to the patients who participated in our clinical study. We have worked tirelessly to bring this device to market to fill this unmet need that addresses a life-threatening condition and may improve their quality of life." said Angel Medical System’s Chief Executive Officer, Dr. David R. Fischell.

The national principal investigator for the ALERTS pivotal clinical study, Dr. C. Michael Gibson of Harvard Medical School, states: "Patients who have had a recent acute coronary syndrome often remain at a high risk of a recurrent event. The AngelMed Guardian System has shown it can identify true heart problems better than patients' symptoms alone as well as in those patients who have no symptoms."

"Helping our patients was always foremost in our minds and hearts." said Angel Medical System’s Chief Operating Officer, David Keenan.

The Guardian System is implanted like a pacemaker, typically in less than an hour under a local anesthetic. This well-studied implantation technique demonstrated an adverse event rate that was also very similar to the rate seen for pacemaker implants. The types of adverse events seen were also similar to those seen with pacemaker implants.

About Coronary Heart Disease and Heart Attacks

According to the American Heart Association, one of every five deaths in the U.S. is attributable to coronary heart disease, making heart attacks the number 1 killer nationwide. Early detection of heart attacks and prompt intervention has been shown to improve clinical outcomes.Despite efforts to educate the public over the past decade, the time from heart attack (MI) symptom onset to arrival at a hospital for treatment has not changed.

In the ALERTS Clinical Study, the median time from symptom onset to arrival at the hospital for a heart attack was one hour.
