 Clinical and economic outcomes.

AspectValueDetailsReferences
Diagnostic accuracySensitivity 85–95%; Specificity 80–92%Meta-analyses of ML for CAD detection across imaging modalities; AI performance comparable to expert readers[9, 47]
Cost savings20–40% (projected)Early economic analyses of health systems implementing AI diagnostics; the magnitude depends on integration, training, and adoption[36]
Time savingsSeconds vs. minutes per imaging studyAutomated preliminary reads shorten per-study assessment; potential gains in triage and turnaround times[35, 55]
Expert agreement≥ 85% (task-specific)HD-IVUS agreement with experts: lumen 85% and stent area 97%; AI-assisted stress ECHO non-inferior, with improved consistency for less-experienced readers[22, 40]

AI: artificial intelligence; CAD: coronary artery disease; HD-IVUS: high-definition intravascular ultrasound; ML: machine learning; ECHO: echocardiography.
