VOA慢速英语 生物标志物对预测心脏病帮助甚微

　　A separate study found no support for a theory that a biomarker called C-reactive protein causes heart disease. Earlier research suggested that the more of the protein in people's blood, the more likely they are to develop heart disease. The new study confirmed a link, but did not find evidence that the C-reactive protein causes the disease. Both studies appeared in the July first issue of Journal of the American Medical Association.

　　The World Health Organization estimates that cardiovascular disease killed seventeen and a half million people in two thousand five. That was thirty percent of all deaths. Eight out of ten happened in low and middle income countries. At current growth rates, the W.H.O. expects the number to reach twenty million by two thousand fifteen.

　　And that's the VOA Special English Health Report, written by June Simms. I'm Steve Ember.

　　一、全文翻译

　　心血管疾病是世界导致死亡的头号诱因。包括心脏病，中风和高血压。多年来，研究人员鉴定出了血管中的一些物质，可以作物生物标志物。这些物质被用来衡量心血管疾病的存在和发展。研究人员越来越多地使用这些生物标志物来鉴别那些患心脏病风险高的人。但是一项新的研究表明，这种方法收效甚微。
