Heart Diseases May Not Be Predicted By Genetic Data

A new study finds that even though a particular genetic variation may increase risk for heart disease, it will not help doctors predict who is likely to get heart disease than using traditional risk factors. The excitement continues to know about the power of gene variations to predict the risk for disease. The risk of cardiovascular trouble through genetic variation did not add more valuable information than the risk caused from high blood pressure, high cholesterol and family history. The data collected by Paynter's team on 22,129 women who participated in the Women's Genome Health Study. Initial stages of study the women were free from any major chronic diseases. Compared with the use of traditional risk factors specific section of the genome, namely chromosome 9p21.3, did not meaningfully show improvement in the ability to predict heart disease over 10.2 years of follow-up. However, Dr. Byron Lee, an assistant professor of cardiology at the University of California, San Francisco, noted that "while in this study, DNA testing did not improve our ability to predict cardiovascular disease, which is based on traditional risk factors like smoking and hypertension, there are literally millions of other specific genetic tests to look at."
