Defibrillator-in-a-Vest May Help Heart Attack Survivors

TUESDAY, March 13, 2018 -- A wearable heart defibrillator reduces the overall risk of early death for heart attack survivors, but not the risk of sudden cardiac death, a new study finds.

The defibrillator -- housed in a lightweight vest worn directly against the skin -- continuously monitors the wearer's heart. It sounds an alarm and/or verbally announces the need for medical care if needed.

If a life-threatening abnormal heart rhythm is detected, the defibrillator delivers a shock to restore normal rhythm.

The study of 2,300 adult heart attack survivors was partly funded by vest maker Zoll Medical Corp.

Patients all had impaired heart function after their heart attack. Those who used the LifeVest wearable defibrillator and took recommended medications were 35 percent less likely to die from any cause within the 90 days of their heart attack than a control group of patients who used medication alone, the study found.

But the risk of sudden cardiac death was the same in both groups, according to the study presented this weekend at the annual meeting of the American College of Cardiology (ACC) in Orlando, Fla.

Research presented at medical meetings is considered preliminary until it is published in a peer-reviewed journal.
