Background Obesity is a significant risk factor for coronary artery disease. While nuclear myocardial perfusion imaging (MPI) and 2D Echo (2DE) are the most commonly used noninvasive imaging modalities in routine clinical practice, obesity often causes technical acquisition problems and artifact potentially leading to false positive results and further downstream testing. Cardiac MRI (CMR) image quality is not similarly limited by obesity. CMR is considered 2nd line for evaluation of chest pain, dyspnea, palpitations and syncope. This study was designed to assess the economic impact and clinical outcome of CMR for initial evaluation of cardiac symptoms in obese patients.
