most adults in u£®s£®have low risk of heart disease£¨ÄѶÈc¼¶£©

¡¡¡¡more than 80 percent of us adults have a less than l o-percent risk of developing heart disease in the next 10 years£¬according to a report in the journal of the american college of cardiology£®just 3 percent have a risk that exceeds 20 percent£®
¡¡¡¡¡°i hope that these numbers will give physicians£¬researchers£¬health policy analysts£¬and others a better idea of how coronary heart disease is distributed in the us population£®¡±lead author dr£®earl s£®ford£¬from the centers for disease control and prevention¡®in atlanta, said in a statement£®  
¡¡¡¡the findings are based on analysis of data from 13£¬769 subjects£¬between 20 and 79 years of age, who participated in the 1nbjrd national health and nutrition exanimation survey from 1988 to 1994£®   À´Ô´£º¿¼ÊÔѧϰÍø
¡¡¡¡overall£¬82 percent of adults had a risk of less than 10 percent, 15 percent had a risk that fell between 1 0 to 20 percent£®and 3 percent had a risk above 20 percent£®
¡¡¡¡the proportion of subjects in the highest risk group increased with advancing age£¬and men were more likely than women to be in this group£®by contrast, race or ethnicity had little effect on risk distributions£®
¡¡¡¡although the report suggests that most adults have a low 10Ò»year risk of heart disease£¬a large proportion have a high or immediate risk£¬dr£®daniel s£®berman£¬from cedars-sinai medical center in los angeles£¬and dr£®nathan d£®wong£¬from the university of california at irvine, note in a related editorial£®
¡¡¡¡aggressive treatment measures and public health strategies are needed to shift the overall population risk downward£¬they add£®
