Article Title: Nomogram for evaluating coronary revascularisation necessity based on multi-parameter coronary CT angiography.
Article Snippet: https://doi.org/10.1016/j.crad.2023.03.012 0009-9260/ 2023 Published by Elsevier Ltd on beha AIM: To build a nomogram model to improve the evaluation of revascularisation necessity using multi-parameter coronary computed tomography (CT) angiography (CCTA).. MATERIALS AND METHODS: In this retrospective study, 335 patients who underwent CCTA and required revascularisation within 1 month were selected and allocated to the revascularisation group; 208 patients who did not undergo revascularisation were allocated to the non-revascularisation group.. CCTA parameters, including CCTA stenosis, plaque qualitative equantitative characteristics, and fractional flow reserve derived from CT angiography (CTFFR), for both groups were analysed and compared.

Article Title: Application and Performance of CT-Fractional Flow Reserve in Non-ST-Segment Elevation Myocardial Infarction.
Article Snippet: Only half of patients with non-ST-segment elevation myocardial infarction (NSTEMI) have obstructive coronary artery disease (CAD) on invasive coronary angiography (ICA).. A noninvasive test that can safely rule out obstructive CAD therefore warrants investigation.. Computed tomography fractional flow reserve (CT-FFR) enables hemodynamic interrogation of lesions identified on coronary computed tomography angiography (CCTA) but it has not been evaluated in NSTEMI.

Article Title: Impact of machine learning-based coronary computed tomography angiography fractional flow reserve on treatment decisions and clinical outcomes in patients with suspected coronary artery disease.
Article Snippet: Objectives This study investigated the impact of machine learning (ML)–based fractional flow reserve derived from computed tomography (FFRCT) compared to invasive coronary angiography (ICA) for therapeutic decision-making and patient outcome in patients with suspected coronary artery disease (CAD).. Methods One thousand one hundred twenty-one consecutive patients with stable chest pain who underwent coronary computed tomography angiography (CCTA) followed ICAwithin 90 days between January 2007 and December 2016were included in this retrospective study.. Medical records were reviewed for the endpoint of major adverse cardiac events (MACEs).
