一項(xiàng)最新研究發(fā)現(xiàn)了肥胖與罹患心房纖維性顫動(dòng)之間的聯(lián)系。該項(xiàng)研究結(jié)果發(fā)表在2004年11月24日《美國(guó)醫(yī)學(xué)會(huì)期刊》。

研究人員研究了5282例參與Framingham心臟研究項(xiàng)目的患者，該項(xiàng)研究項(xiàng)目是由美國(guó)國(guó)立心臟、肺臟與血液研究院(NHLBI, Bethesda, MD, USA)主持的，在研究項(xiàng)目開始的時(shí)候患者沒有心房纖維性顫動(dòng)。這些受試者根據(jù)體重指數(shù)分成三個(gè)類別：正常、超重與肥胖。在大約14年的時(shí)間內(nèi)，研究人員發(fā)現(xiàn)心房纖維性顫動(dòng)發(fā)生率隨著體重指數(shù)的增加而增加，男性與女性患者都是如此。那些體重指數(shù)最高的患者，罹患心房纖維性顫動(dòng)的風(fēng)險(xiǎn)增加了50％。

根據(jù)Framingham心臟研究項(xiàng)目主任、該研究的共同作者Daniel Levy醫(yī)生的說法，這些研究結(jié)果需要得到其他研究項(xiàng)目的證實(shí)。如果這些研究結(jié)果得到進(jìn)一步證實(shí)，Levy醫(yī)生相信，控制體重除了能夠降低患高血壓、糖尿病以及其他肥胖相關(guān)性并發(fā)癥之外，還能夠降低罹患心房纖維性顫動(dòng)的風(fēng)險(xiǎn)。

Obesity Linked to Atrial Fibrillation
 
A new study has found an association between obesity and the risk of developing atrial fibrillation (AF). The finding was reported in the November 24, 2004, issue of the Journal of the American Medical Association.

Investigators studied 5,282 participants in the Framingham Heart Study, conducted by the U.S. National Heart, Lung, and Blood Institute (NHLBI, Bethesda, MD, USA), who did not have AF when the study began. These subjects were divided into three categories of body mass index (BMI): normal, overweight, and obese. Over a period of about 14 years, the investigators found that the incidence of AF increased as BMI increased, for both men and women. For those with the highest BMI, the AF risk could increase by 50%.

These findings should be confirmed by other observational studies, according to Daniel Levy, M.D., a co-author of the study and director of the Framingham Heart Study. If the study is validated, Dr. Levy believes weight control may lower the risk for AF, in addition to reducing risk for hypertension, diabetes, and other obesity-related complications.
