Rate of inappropriate coronary computed tomographic angiography before or after guideline publication. (A) Patients with ejection fraction ≥50% and pretest probability ≤15% should have other diseases excluded. (B) Patients with ejection fraction ≥50% and pretest probability between 50% and 85% should take stress tests before coronary computed tomographic angiography. (C) Patients with ejection fraction <50% and without typical angina should take stress tests before coronary computed tomographic angiography. (D) For patients with ejection fraction <50% and typical angina or ejection fraction ≥50% and pretest probability ≥85%, invasive coronary angiography was necessary. The bars indicate the 95% confidence interval.
