Coronary angiography is the gold standard for diagnosing coronary stenosis, but the degree of stenosis is not linearly related to myocardial ischemia.
Design
Single-center study
May support QFR for hemodynamic assessment beyond angiography; leaves open routine adoption pending higher-level evidence.
