Khera writes that the bill was passed based on input from the controversial\u00a0Society for Heart Attack Prevention and Education (SHAPE), with no input or support from the AHA or ACC, and with no basis in evidence derived from randomized and controlled clinical trials. &#8220;The added costs and potential risks of these imaging tests necessitate a higher level of evidence before considering a broad legislative mandate,&#8221; Khera writes.<\/p>\n<p>In <a href=\"http:\/\/archinte.ama-assn.org\/cgi\/content\/extract\/171\/4\/281\">an editor&#8217;s note<\/a>, Rita Redberg writes that &#8220;at a time when states are facing crises in health insurance spending and cutting lifesaving treatments, and when Texas leads the nation in the percentage of residents without health insurance, it is remarkable that Texas has chosen this path.&#8221;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Three papers in\u00a0Archives of Internal Medicine scrutinize the role of cardiovascular screening tests not only in medicine but in legislation.
