Article Synopsis
- Coronary computed tomography angiography (CCTA) is used to evaluate cardiovascular risk by quantifying coronary plaque, and deep learning technology helps automate this process.
- A study involving 2803 patients analyzed how age and sex affect coronary plaque volume and its relation to the risk of myocardial infarction, showing that plaque volume increases with age and is typically higher in men.
- Patients with coronary plaque in the ≥75th percentile were found to have a significantly higher risk of myocardial infarction compared to those below the 50th percentile, suggesting that deep learning-based plaque measurements can effectively predict cardiac events.

Article Synopsis
- * Recent advancements in cardiac CT scans allow for accurate measurement of diffuse fibrosis through delayed phase imaging.
- * This review discusses the methods for measuring CT extracellular volume (CT-ECV) and highlights its potential to predict health outcomes in patients with cardiac diseases.
Background Quantifying the fibrotic and calcific composition of the aortic valve at CT angiography (CTA) can be useful for assessing disease severity and outcomes of patients with aortic stenosis (AS); however, it has not yet been validated against quantitative histologic findings. Purpose To compare quantification of aortic valve fibrotic and calcific tissue composition at CTA versus histologic examination. Materials and Methods This prospective study included patients who underwent CTA before either surgical aortic valve replacement for AS or orthotopic heart transplant (controls) at two centers between January 2022 and April 2023.

As such, the evaluation and management of cancer therapy related complications has become increasingly important, including cardiovascular complications. These have been captured under the umbrella term "cardiotoxicity" and include left ventricular dysfunction and heart failure, acute coronary syndromes, valvular abnormalities, pericardial disease, arrhythmia, myocarditis, and vascular complications.
