Providing peace of mind.

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.

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.

~6hr. Faster Speed-to-ER

Speed-to-ER can save your life. In the ALERTS study, Guardian patients arrived at the ER with a median time that was 5.7 hrs. earlier when compared to relying on symptoms alone.1


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 attack within the next five years.2 The risk is much higher if you are diabetic, a smoker, or have kidney disease, or multi-vessel disease. The Guardian can help.

The Guardian is the world’s first and only heart attack warning system approved by the FDA.


The device fills an unmet medical need by providing more effective diagnosis of a life-threatening condition compared to relying on patient symptoms alone.


Live with peace of mind.

You may not know you are having another heart attack. Symptoms alone are not reliable indicators.

  • Up to 45%

    Of heart attacks are “silent” without any noticeable symptoms.3


  • 25%

    Of heart attacks occur with atypical symptoms (no classical chest pain).4


  • 200K

    Of heart attacks happen to people who have already had a heart attack (each year).5



Guardian is your early heart attack warning system.

Living with the fear and uncertainty of not knowing when or where you might have another ACS event can be debilitating - thus 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 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 dramatically increases the risk of permanent heart damage and heart failure. In clinical studies, Guardian patients arrived at the hospital ~6 hours earlier than patients relying on symptoms alone.
