Stem cells can be harvested long after death: study

Pot Belly Boosts Risk of Sudden Cardiac Death: Study

HealthDay – 1 hr 35 mins ago WEDNESDAY, May 9 (HealthDay News) -- A "spare tire" around the midsection raises the odds of sudden cardiac death in obese people, a new study finds.

A larger waist-to-hip ratio matters even more than body-mass index when it comes to sudden cardiac death risk, said study researcher Dr. Selcuk Adabag, an associate professor of medicine at the University of Minnesota in Minneapolis. Body-mass index is a measure of weight relative to height used to determine normal weight and obesity.

Obesity, a moderate risk factor for sudden cardiac death, and apple-shaped bodies often go hand in hand.

"The significance of this study is that it shows that abdominal obesity is an independent risk factor for sudden cardiac death, even after accounting for factors such as diabetes, hypertension and coronary heart disease," said Adabag, who is also a cardiac electrophysiologist at the Veterans Administration Medical Center in Minneapolis.

Adabag was scheduled to present the findings Wednesday at the annual meeting of the Heart Rhythm Society in Boston.

Sudden cardiac death is responsible for more than 250,000 deaths in the United States each year, according to the Centers for Disease Control and Prevention. It is defined as death that occurs within an hour of initial symptoms. Besides obesity, risk factors include coronary heart disease and heart rhythm problems.

For the study, Adabag looked at the records of more than 15,000 people with an average age of 54 from four U.S. locales who were enrolled in the Atherosclerosis Risk in Communities Study. Over 13 years, more than 300 of the participants experienced sudden cardiac death.

After Adabag took into account age, sex, race, education, smoking status and family history of heart disease, he found that body-mass index, waist circumference and waist-to-hip ratio all were linked with sudden cardiac death.

"I expected there would be some relationship with all
