Heart Defibrillators Help Patients With HCM
Most people assume young athletes are the pinnacle of health, but a rare condition can stop their hearts in the blink of an eye.
Posted — UpdatedHypertrophic cardiomyopathy is a genetic disease, which causes the heart wall to thicken. Paul McSweeney, 22, and his mom, Mary, learned he had HCM 11 years ago.
"They said that he should limit his activity which is really tough for an 11-year-old kid and that he could live a normal life, but that there was a risk of sudden death," Mary said.
In hopes of reducing that risk, Paul got an implantable defibrillator, which sends electric shocks to the heart if it starts beating irregularly. One day, the defibrillator started working when Paul took a nap after stressful studying for exams.
A study published in the Journal of the American Medical Association shows implantable defibrillators can offer hope to many HCM patients.
The device may help even if patients have only one risk factor such as sudden death in a close relative, unexplained fainting or massive thickening of the heart wall. Officials said Paul is clearly at risk since the defibrillator had to shock his heart back to normal months before he needed it.
The study followed about 500 HCM patients with implantable defibrillators. Over three years, the devices delivered life saving shocks to 103 patients with irregular heartbeats. About 20 percent experienced device complications and one patient died due to a defibrillator malfunction.
