Atrial Fibrillation Linked to Sudden Cardiac Death

Atrial fibrillation may raise the risk of sudden cardiac death, according to findings from two large population-based cohorts, according to a report in MedPage Today.

The risk of sudden cardiac death was elevated 3.26-fold with incident atrial fibrillation in multivariate analysis of the ARIC (Atherosclerosis Risk in Communities) study, Lin Y. Chen, MD, MS, of the University of Minnesota Medical School in Minneapolis, and colleagues found.

And the risk was 2.14 times higher after onset of Afib in the Cardiovascular Health Study (CHS), the group reported online in the Archives of Internal Medicine.

If confirmed, the sudden cardiac death finding "adds to our evolving understanding that Afib is not a benign condition," they wrote.

Sudden Death Risk Higher in Black Women

Researchers have determined that postmenopausal women have specific independent risk factors that drive their incidence of sudden cardiac death (SCD) and being African American is one of them.

African-American women had a significant 61% increased risk of SCD compared with other races, after all known risk factors and sociodemographic risk factors were accounted for, according to Monica L. Bertoia, MPH, PhD, of Harvard School of Public Health in Boston, and colleagues.

Of the 418 women who experienced SCD, investigators identified these characteristics, in addition to traditional risk factors, that put them at increased risk:

Caught on Camera: Woman Goes Into Cardiac Arrest During Traffic Stop

ENCINO (CBS2) — A video taken by the California Highway Patrol may be the first time a camera has captured all of the events leading up to a cardiac arrest following the use of a TASER® electronic control device.

On June 4, CHP officers stopped to check on the welfare of 50-year-old Angela Jones after finding her sitting in a parked vehicle on Haskell Avenue, near the Ventura (101) Freeway.

A camera mounted on the officers’ car captured the incident.

“How much have you had to drink tonight?” an officer asked the Studio City resident.

“Nothing,” Jones said.

“Nothing?” the officer responded. “What about medication or drugs?”

Officers questioned Jones for 15 minutes, suspecting she might be under the influence, and then asked to look through her purse.

FDA Considers Reclassification of AEDs

By Teresa McCallion, EMT-B, Journal of Emergency Medical Services

Expert panel recommends higher safety standards

Blood pressures are rising over a move by the Food and Drug Administration (FDA) to classify automated external defibrillators (AEDs) as a Class III high-risk medical device, requiring a more rigorous pre-market approval (PMA) application process. The FDA is expected to make a final decision by the end of this year.

Do People Turn to Twitter to Learn CPR Info?

Amid snarky comments and links to cat videos, some Twitter users turn to the social network to find and post information on cardiac arrest and CPR, according to a new study.

Over a month, researchers found 15,324 messages - known as tweets - on Twitter that included specific information about resuscitation and cardiac arrest.

"From a science standpoint, we wanted to know if we can reliably find information on a public health topic, or is (Twitter) just a place where people describe what they ate that day," said the study's lead author Dr. Raina M. Merchant.

According to the researchers, they did find some people using Twitter to send and receive a wide variety of information on CPR and cardiac arrest, including their personal experiences, questions and current events.

Patients More Likely to Survive In-Hospital Cardiac Arrest Today

A new study published today in the New England Journal of Medicine finds that survival in patients who experience a cardiac arrest in the hospital has increased significantly over the past decade. The study, led by cardiologists at University of Iowa Hospitals and Clinics and Saint Luke's Mid America Heart Institute and the University of Missouri in Kansas City, also shows that this improvement has been accompanied by lower rates of neurological disability among those who survive.

Use of AEDs in the Home Yields High Survival Rates

Most cases (80%) of sudden cardiac arrest (SCA) occur in the home. A new suggests that deployment of automated external defibrillators (AEDs) in homes may be an important additional strategy for SCA treatment. Using a prospectively-designed post-market study, researchers identified 25 cases in which a privately owned AED was used to treat SCA, including two uses on children.

Results indicate:

Can "Heel CPR" Help?

LOS ANGELES--Is “Heel CPR” a viable alternative to “Hands-Only CPR” for lone rescuers, who may become fatigued and unable to apply adequate force while waiting for EMS to arrive?

Fernando Perez, MD, and Robert H. Trenkamp, Jr., EMT-P, from “Saving Lives in Chatham County explored this question and presented their research earlier this month at the American Heart Association Resuscitation Science Symposium. 

Trenkamp, who serves on the Sudden Cardiac Arrest Foundation Board of Directors, reported the results of examining the duration an adult could maintain two-inch deep chest compressions at a rate of at least 100 per minute using “Hands-Only” and then Pedal Compressions (“Heel CPR”) in two sequential tests. 

Novel Low Energy ICD to be Studied

A novel electrotherapy greatly reduces the energy needed to shock a heart back into rhythm, potentially making ICDs more acceptable to patients.

ICD Battery Alarms Us All

You may have noticed we posted an article (linked to the original Reuters piece) concerning a technology breakthrough that could have major impact on future need for ICD and pacemaker batteries.

Now we have another story to tell on the subject.

What does an ICD battery alarm sound like? Alarm you say, what alarm?
Ah, if you have an ICD, then one day you are likely to hear this sound or something similar.

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.
