Computed Tomography Coronary Angiography Is Feasible and Reliable for Proximal Coronary Segment Interpretation in Patients with Elevated Body Mass Index.

Computed tomography coronary angiography (CTCA) is under-utilised in detecting coronary artery disease (CAD) in obese patients due to concerns about non-evaluable testing. We hypothesise that these concerns are predominantly related to smaller and branch coronary vessels, and CTCA remains adequate for proximal segment stenosis interpretation, which has significant clinical implications. This retrospective cohort study, on consecutive patients referred for CTCA for suspected CAD, grouped patients by body mass index.

Objectives: To assess the image quality of ultra-high-resolution (UHR) virtual monoenergetic images (VMIs) at 40 keV compared to 70 keV, using spectral photon-counting CT (SPCCT) and dual-layer dual-energy CT (DECT) for coronary computed tomography angiography (CCTA).
Methods And Materials: In this prospective IRB-approved study, 26 high-risk patients were included. CCTA was performed both with an SPCCT in UHR mode and with one of two DECT scanners (iQOn or CT7500) within 3 days.

Coronary artery bypass grafting vs. percutaneous coronary intervention in severe ischaemic cardiomyopathy: long-term survival.
Eur Heart J
January 2025
Department of Cardiology, Alfred Health, 55 Commercial Road, Melbourne, VIC 3004, Australia.
Article Synopsis
- The study investigates long-term survival outcomes for patients with severe ischaemic cardiomyopathy who underwent either coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) due to a lack of recent trial data.
- Using records from Australian and New Zealand cardiac registries between 2005 and 2018, researchers analyzed data from 2042 patients, with 1451 treated by CABG and 591 by PCI, adjusting for various risk factors.
- Results showed CABG patients had significantly lower long-term mortality compared to those who received PCI, although there were no differences in in-hospital mortality; however, CABG was associated with a higher risk of peri-procedural strokes and a longer hospital stay
