| アブストラクト | Background: The evaluation of stable coronary artery disease (SCAD) has evolved, and contemporary clinical practice guidelines emphasize the importance of in-depth consideration of procedure indications, risk stratification, and results of non-invasive imaging tests. However, little is known about the appropriate selection of imaging modalities for ischemia evaluation and the comparative cost-effectiveness in real-world clinical practice. Methods and Results: The Japanese Comprehensive Health-Economic Assessment for Appropriate Cardiac Imaging Strategy including Outcome and cost-effectiveness in Stable Coronary Artery Disease Study (J-CONCIOUS), a multicenter observational study, was designed to prospectively enroll 2,500 patients with suspected or known SCAD, register clinical information and administrative records, and follow patients for 3 years. Any diagnostic or cardiac imaging modality (including stress tests using electrocardiography, echocardiography, or myocardial perfusion imaging; coronary computed tomographic angiography; and/or invasive coronary angiography with or without fractional flow reserve assessment) is acceptable. Clinical endpoints, such as all-cause mortality, cardiac death, and non-fatal myocardial infarction, will be obtained, along with quality of life assessment using the Seattle Angina Questionnaire. The cost-effectiveness of individual assessment patterns will be quantified by analysis of Diagnosis Procedure Combination (DPC) data, and quality-adjusted life years and the incremental cost-effectiveness ratio will be calculated. Conclusions: J-CONCIOUS is expected to establish a risk-based and cost-effective imaging strategy for the detection and evaluation of functional myocardial ischemia and/or anatomical coronary imaging in Japan. |
