Research Shows Majority of Americans Unaware of Severity and Prevalence of Sudden Cardiac Arrest The Heart Rhythm Society Launches Sudden Cardiac Arrest Awareness Month in October

WASHINGTON, Oct. 1 /PRNewswire/ -- More than 250,000 deaths occur each year as a result of sudden cardiac arrest (SCA). In fact, SCA claims one life every two minutes, taking more lives each year than breast cancer, lung cancer or AIDS. Yet, according to a recent survey issued by the Heart Rhythm Society, more than 70 percent of Americans not only underestimate the seriousness of SCA, but also believe SCA is a type of heart attack.

The Heart Rhythm Society is kicking-off SCA Awareness Month in October and launching a multi-year campaign to call attention to the need for more public education on this very serious heart health issue. To decrease the death toll from SCA, it is important for the U.S. public to understand what SCA is, what the symptoms and warning signs are and how to respond and prevent SCA from occurring.

"SCA Awareness Month represents a critical initiative by the Heart Rhythm Society to raise awareness for SCA and help the public become more familiar with what it is, how it affects people and what can be done to help save lives," said Richard L. Page, MD, FHRS, president of the Heart Rhythm Society. "The Heart Rhythm Society is committed to a long term approach to educating the public and ultimately decreasing the number of lives claimed by SCA each year."

SCA vs. Heart Attack - Electrical vs. Plumbing

The majority of Americans do not know the difference between SCA and a heart attack which can lead to people overlooking and missing warning signs that may indicate the risk of SCA. SCA occurs when the heart stops working and no blood can be pumped to the rest of the body, the heart's "electrical system" malfunctions. Whereas a heart attack, a condition technically known as a myocardial infarction (MI), is a "plumbing problem" in which a blockage in a blood vessel interrupts the flow of blood to the heart, causing an area of dead heart muscle.

Population at Risk

SCA occurs abruptly and without warning, and two-thirds of SCA deaths occur without any prior indications of heart disease. In fact, SCA can happen to people of all ages and health conditions. Some symptoms that may indicate someone is at risk for SCA include:

  • A previous heart attack, individuals who have had a heart attack are at greater risk of SCA - 75 percent(1) of people who die of SCA show signs of a previous heart attack.
  • A family history of sudden death, heart failure or massive heart attack.
  • An abnormal heart rate or rhythm of unknown cause.
  • An unusually rapid heart rate that comes and goes, even when the person is at rest.
  • Episodes of fainting of unknown cause.
  • A low Ejection Fraction (EF): The Ejection Fraction is a measurement of how much blood is pumped by the ventricles with each heart beat. A healthy heart pumps 55 percent or more of its blood with each beat, less than 35 percent indicates an elevated risk of SCA.

Responding to SCA - Time is Everything

Time-to-treatment is critical when considering the chance of survival for an SCA victim. Ninety-five percent of those who experience SCA die because they do not receive life-saving defibrillation within four to six minutes, before brain and permanent death start to occur. The recent survey conducted by the Heart Rhythm Society asked people how they would respond if they witnessed an SCA event and results showed 42 percent would call 911 and wait for emergency personnel to respond, 35 percent would administer CPR or chest compressions and only 16 percent of respondents would use an Automatic External Defibrillator (AED). The Heart Rhythm Society advises the following actions in response to a potential SCA emergency:

  1. Know the signs of SCA in order to react quickly. SCA strikes immediately and without warning. Victims will fall to the ground/collapse, become unresponsive and will not breathe normally, if at all.
  2. Call 911 as soon as possible.
  3. Start CPR as quickly as possible (note: hands only CPR is proven to be just as effective).
  4. Use an AED if one is available on-site.

Preventing and Treating SCA

There are a number of things people can do to decrease the likelihood of becoming a victim of sudden cardiac arrest. The Heart Rhythm Society offers the following advice:

  1. Live a healthy lifestyle - exercising regularly, eating healthy foods, maintaining a healthy weight and avoiding smoking can help reduce the chances of SCA.
  2. Treat and monitor health conditions that can contribute to heart problems, including high blood pressure, high cholesterol and diabetes. Patients should ask their doctor about their Ejection Fraction and determine if they are at risk for SCA.
  3. For some patients, preventing SCA means controlling or stopping the abnormal heart rhythms that may trigger life-threatening arrhythmias through proper medication, implantable cardioverter defibrillators (ICDs), and in some, cases surgical procedures such as ablation.
  4. Patients should know their family history and understand their risk for other cardiovascular related conditions, like heart failure.

In the recent national survey, nearly 60 percent of respondents did not know that implantable cardioverter defibrillators (ICDs) are the most effective treatment to protect those at risk of SCA.

"One of the most important steps toward better health is talking with your doctor about your individual heart health and potential risk factors," added Dr. Page. "The Heart Rhythm Society encourages individuals to educate themselves about their personal health and also be an advocate for others to do the same."
