Wash U, U of I Scientists Use 3-D Printer To Help Create Prototype Next-Gen Pacemaker

Researchers at the University of Illinois at Urbana-Champaign and Washington University in St. Louis have developed a new device that may one day help prevent heart attacks.

Unlike existing pacemakers and implantable defibrillators that are one-size-fits-all, the new device is a thin, elastic membrane designed to stretch over the heart like a custom-made glove. The membrane is imprinted with a network of electrodes that can monitor cardiac function and deliver an electrical impulse to correct an erratic heartbeat.
This video shows a rabbit heart that has been kept beating outside of the body in a nutrient and oxygen-rich solution. The new cardiac device -- a thin, stretchable membrane imprinted with a spider-web-like network of sensors and electrodes -- is custom-designed to fit over the heart and contract and expand with it as it beats.

University of Illinois materials scientist John Rogers co-led the team that invented the new device.

Genes hold key to unexplained cardiac deaths in young people

New Zealand and Australian doctors are on the verge of discovering why some young people suddenly fall victim to cardiac death.Chris Semsarian

Preliminary numbers show 460 sudden cardiac deaths have been reported in both countries in the past three years, with 51 of these occurring in New Zealand, Australian cardiologist Chris Semsarian says.

Dr Semsarian, who presented early results of his three-year study at the Royal College of Pathologists of Australasia Pathology Update in Melbourne over the weekend, says gene analysis could confirm the underlying cause of these unexplained deaths.

Final results are expected in the middle of this year, he says.

Sudden cardiac death a silent killer

Sudden cardiac death in young people aged between one and 35 who are considered healthy is "like getting hit by a bolt of lightning", Dr Semsarian told New Zealand Doctor.

New class of drugs developed to treat cancer, reduces sudden cardiac death risk after heart attack

A researcher at the Cardiovascular Institute (CVI) at Rhode Island, The Miriam and Newport hospitals has found that a new class of drugs, originally developed to treat cancer, reduces sudden cardiac death risk after a heart attack. The findings were published online in advance of print in the Journal of the American College of Cardiology.

"Currently, there are limited options to reduce sudden cardiac death following a heart attack," said principal investigator Samuel C. Dudley, M.D., Ph.D., chief of cardiology at the CVI. "The benefit of most drugs is limited, and they have additional side effects. Defibrillators are an option, but they cannot be safely implanted for 40 days following a heart attack."

Dudley continued, "This finding gives us hope for a new treatment model, and if approved, will provide physicians with new options to lower patients' risk of death from cardiac arrest."

Poll Reveals Nearly 80 Percent of Employed Adults Can’t Locate Their Workplace’s Defibrillator

CINCINNATI — Each year, approximately 300,000 people suffer out-of-hospital sudden cardiac arrests (SCA) that require revival from an automated external defibrillator (AED). According to the results of a survey commissioned by Cintas Corporation (NASDAQ: CTAS), a leader in first-aid and safety programs, although many workplaces have AEDs on site, it’s likely that a majority of workers would not be prepared to locate and use the units. The survey, conducted online by Harris Interactive® among 2,019 adults ages 18 and older (of whom 916 are employed), found that 79 percent of employed adults do not know where their workplace’s AED is located.

What you need to do when you are not on the ambulance or in the hospital

OK, Teammates. Here's how it all sorts out:

First, if you see a person have a cardiac arrest and you are in an ambulance or in the Emergency Department, you already know what you need to do.

BUT, if you are in a situation where when you see someone arrest, you need to call for an ambulance - and I don't care whether you are a doctor, a nurse, a paramedic, or an EMT - the odds of your being able to perform Guideline-Compliant Chest Compressions ("GC3's") from the time of the arrest until the ambulance crew is "hands on" at the victim are slim-to-none.

First of all, we have studied chest compression stamina and chest compression depth, and I can assure you that you are an exception, if you are able to perform GC3's until the ambulance crew takes over, when you are using what we teach in a normal CPR class.

Mission & Vision

The mission of the Sudden Cardiac Arrest (SCA) Foundation is to prevent death and disability from sudden cardiac arrest. The vision of the SCA Foundation is to increase awareness about sudden cardiac arrest and influence attitudinal and behavioral changes that will reduce mortality and morbidity from SCA.
