Echocardiogram showing left ventricle Screening<unk>  for<unk>  disease can be problematic because of low prevalence and inconclusive performance of various tests that have been used. Nevertheless,<unk><unk>  among seemingly healthy individuals attracts much public and legislator attention because of its visible and tragic nature. As an example, the Texas Legislature appropriated US$1 million for a pilot study of statewide<unk> screening in 2007. The study employed a combination of questionnaire, examination and electrocardiography for 2,506 student<unk> , followed by echocardiography for 2,051 of them, including any students with abnormal findings from the first three steps. The questionnaire alone flagged 35% of the students as potentially at risk, but there were many false positive results, with actual disease being confirmed in less than 2%. Further, a substantial number of screen-positive students declined repeated recommendations for follow-up evaluation. (Individuals who are conclusively diagnosed with<unk>  disease are usually told to avoid competitive sports.) It should be stressed that this was a single pilot program, but it was indicative of the problems associated with large-scale screening, and consistent with experience in other locations with low prevalence of<unk><unk>  in<unk> .
