GUARDIAN, the first and only FDA-approved heart attack warning system

24/7 Monitoring

Continuous monitoring and detection of abnormal changes in your heart’s activity, including silent heart attacks.1

Real-time Alerts

Immediate alert to a heart attack onset. Guardian will provide an Emergency alarm comprising a loud beeping, red flashing light, and a vibration in your chest indicating you should call 9-1-1 and be transported to the ER.

Decreased Pre-hospital Delay

Quickly arriving at the ER when having a heart attack can save your life and decrease heart damage. In the ALERTS study, Guardian patients arrived an average of 6.3 hours earlier than relying on symptoms alone.2

Are you at risk of having another heart attack?

If you had a heart attack, you are at a 20% higher risk of having another within the next five years.3 The risk is even higher if you are diabetic, a smoker, or have kidney disease, or multi-vessel coronary disease. The Guardian can help.

Guardian is your early heart attack warning system.

Living with the fear and uncertainty of not knowing when or where you might have another heart attack can be debilitating - reducing your quality of life. Guardian continuously monitors your heart and will alert you if it detects the onset of a coronary occlusion, even when symptoms are not present, providing increased peace of mind.


Get to the ER faster for critical care.

Reducing pre-hospital delay improves your heart’s chances of obtaining benefit from medical treatment. The Guardian helped get patients to the ER in under 2 hours.

A delay in critical care increases the risk of permanent heart damage and heart failure. In clinical studies, Guardian patients arrived at the hospital about 6 hours earlier than patients relying on symptoms alone.
