Incidence Jumps Among Young People, Especially Women.(sudden cardiac death)
2001 MAR 15 - (NewsRx.com & NewsRx.net) -- In the first study to examine U.S. trends in sudden cardiac death (SCD) among the young, researchers have found that the number of adolescents and young adults who die from sudden cardiac arrest has gone up in the past decade.
The March 1,2001, report comes from the American Heart Association's 41st Annual Conference on Cardiovascular Disease Epidemiology and Prevention, held this year in San Antonio, Texas. The yearly death totals from sudden cardiac death for teens and young adults climbed from 2,719 in 1989 to 3,000 in 1996 - a jump of about 10%.
"Explaining these trends will require more scientific studies. But we can speculate that some of the increase may be related to the increased prevalence of cardiovascular risk factors, such as obesity among adolescents. It may also be due to a poor rate of recognizing SCD in younger patients and applying cardiopulmonary resuscitation," says Zhi-Jie Zheng, MD, PhD, lead author of the study and an epidemiologist in the Cardiovascular Health Branch of the National Center for Chronic Disease Prevention and Health Promotion, at the U.S. Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia.
In analyzing national death certificate data for people aged 15-34, researchers found that of the 23,320 individuals who died suddenly of cardiac arrest between 1989 and 1996, 71% were men. Though the rate of SCD was twice as high among men as in women, the new numbers represent a 30% increase in SCD over the eight-year period among adolescent and young adult females. SCD among males increased by 10%.
"Unfortunately, we can't explain why there is a large increase in SCD among this age group of young women," says Zheng. "However, combined with the findings of our previous study in an older group of women, we think this trend is real."
In a study presented at the American Heart Association's Scientific Sessions 2000 meeting last November, Zheng reported that women aged 35-44 had a 15% increase in SCD during the same period.
