Heart Attack Statistics

The chances of surviving an ACS event have never been better, thanks in large part to advancements in intervention not only at the hospital, but in the ambulance as well. Still the facts surrounding ACS events are irrefutable.

  • About 805,000 people will suffer a heart attack this year.1

  • Another 200,000 will have a recurrent coronary event.1

  • It is estimated that 45% of these events will be “silent” heart attack with few, if any recognized symptoms.2

A heart attack, also called a myocardial infarction, can be fatal. One person dies every 34 seconds in the United States from cardiovascular disease.1

While advances in cardiac interventions and therapies have improved patient outcomes, reliably getting patients to the hospital in a timely manner presents one of the greatest challenges today. This is critical to improving patient outcomes.

Patient Benefit

Guardian provides many important benefits including:
  • allowing patients to seek ER care even when the ACS event has no symptoms (asymptomatic)
  • allowing patients to arrive at the ER in a timely fashion, which is important in increasing the benefit of intervention in saving heart muscle.
  • Emergency Alarms more accurately detect ACS events than symptoms
  • decreasing the rate of going to the ER unnecessarily

*A portion of the ALERTS subjects were evaluated in a sub-study that examined quality of life. The results showed that many patients reported having less stress, improvements in sleep, less anxiety during exercise, and improvements in other areas.
