New clinical trials published in peer-reviewed journals and articles through December 2011 were also reviewed and incorporated when relevant. Furthermore, because of the extended development time period for this guideline, peer review comments indicated that the sections focused on imaging technologies required addi- tional updating, which occurred during 2011. Therefore, the evidence review for the imaging sections includes published literature through December 2011. Searches were limited to studies, reviews, and other evi- dence in human subjects and that were published in English. Key search words included but were not limited to the following: accuracy, angina, asymptomatic patients, cardiac magnetic resonance (CMR), cardiac rehabilitation, chest pain, chronic angina, chronic coronary occlusions, chronic ischemic heart disease (IHD), chronic total occlusion, con- nective tissue disease, coronary artery bypass graft (CABG) versus medical therapy, coronary artery disease (CAD) and exercise, coronary calcium scanning, cardiac/coronary com- puted tomography angiography (CCTA), CMR angiography, CMR imaging, coronary stenosis, death, depression, detec- tion of CAD in symptomatic patients, diabetes, diagnosis, dobutamine stress echocardiography, echocardiography, el- derly, electrocardiogram (ECG) and chronic stable angina, emergency department, ethnic, exercise, exercise stress test- ing, follow-up testing, gender, glycemic control, hyperten- sion, intravascular ultrasound, fractional flow reserve (FFR), invasive coronary angiography, kidney disease, low-density lipoprotein (LDL) lowering, magnetic resonance imaging (MRI), medication adherence, minority groups, mortality, myocardial infarction (MI), noninvasive testing and mortal- ity, nuclear myocardial perfusion, nutrition, obesity, out- comes, patient follow-up, patient education, prognosis, prox- imal left anterior descending (LAD) disease, physical Fihn et al Stable Ischemic Heart Disease: Full Text e359 activity, reoperation, risk stratification, smoking, stable is- chemic heart disease (SIHD), stable angina and reoperation, stable angina and revascularization, stress echocardiogra- phy, radionuclide stress testing, stenting versus CABG, un- protected left main, weight reduction, and women.
