Objectives: to determine the diagnostic performance of non-invasive FFR derived from standard acquired coronary computed tomography angiography (CTA) datasets (FFRCT) for the diagnosis of myocardial ischemia in patients with suspected stable coronary artery disease (CAD).Methods.Prospective study included 16 patients ((m/f – 13/3 mean age 47.8 ± 2.3 years) with CAD and coronary stenosis 40–75% lumen reduction. Coronary CTA was performed prior to ICA with invasive FFR measurement. FFRCT was calculated and interpreted in a blinded fashion by an independent Core Laboratory (HeartFlow, USA). Results were compared to invasively measured FFR, with ischemia defined as FFRCT or FFR ≤ 0.80.Results. The area under the receiver operating characteristic curve (95% CI) for FFCT was 0.90. Per-vessel sensitivity and specificity to identify myocardial ischemia were 91% and 89% for FFRCT.Conclusion.FFRCT provides high diagnostic accuracy, and discrimination for the diagnosis of hemodynamically significant CAD with invasive FFR as the reference standard.

The objective of this study was to determine how coronary computed tomography angiography (CCTA) can be employed to detect coronary artery disease in hospital employees, enabling early treatment and minimizing damage. All employees of our hospital were assessed using the Framingham Risk Score. Those with a 10-year risk of myocardial infarction or death of >10% were offered CCTA; the Coronary Artery Disease Reporting and Data System (CAD-RADS) score was the outcome. A total of 3923 hospital employees were included, and the number who had received CCTA was 309. Among these 309, 31 (10.0%) had a CAD-RADS score of 3–5, with 10 of the 31 (32.3%) requiring further cardiac catheterization; 161 (52.1%) had a score of 1–2; and 117 (37.9%) had a score of 0. In the multivariate logistic regression, only age of ≥ 55 years (p < 0.05), hypertension (p < 0.05), and hyperlipidemia (p < 0.05) were discovered to be significant risk factors for a CAD-RADS score of 3–5. Thus, regular and adequate control of chronic diseases is critical for patients, and more studies are required to be confirmed if there are more significant risk factors.
