Mortality impact of low CAC density predominantly occurs in early atherosclerosis: explainable ML in the CAC consortium
Original TOC summary: We used SHAP, an explainable machine learning (ML) technique, to determine the risk predictive value and age interaction of coronary artery calcium (CAC) characteristics among 63,215 asymptomatic patients in the CAC consortium. The addition of CAC density and number of calcified vessels to an ML model with clinical characteristics + CAC did not improve prediction for all-cause mortality (p = 0.23), but did improve for cardiovascular mortality (p = 0.03). Lower CAC density increased mortality, particularly very low CAC density ≤0.75, which occurred predominantly in CAC1-100. Explainable ML should be applied in clinical research for transparent predictive modeling.2022 use of coronary computed tomographic angiography for patients presenting with acute chest pain to the emergency department: An expert consensus document of the Society of cardiovascular computed tomography (SCCT): Endorsed by the American College of Radiology (ACR) and North American Society for cardiovascular Imaging (NASCI)
Coronary computed tomography angiography (CTA) improves the quality of care for patients presenting with acute chest pain (ACP) to the emergency department (ED), particularly in patients with low to intermediate likelihood of acute coronary syndrome (ACS). The Society of Cardiovascular Computed Tomography Guidelines Committee was formed to develop recommendations for acquiring, interpreting, and reporting of coronary CTA to ensure appropriate, safe, and efficient use of this modality. Because of the increasing use of coronary CTA testing for the evaluation of ACP patients, the Committee has been charged with the development of the present document to assist physicians and technologists.Comparison of coronary atherosclerotic plaque progression in East Asians and Caucasians by serial coronary computed tomographic angiography: A PARADIGM substudy
To investigate potential differences in plaque progression (PP) between in East Asians and Caucasians as well as to determine clinical predictors of PP in East Asians.Accelerating the future of cardiac CT: Social media as sine qua non?
The vision for the Journal of Cardiovascular Computed Tomography's social media efforts is to amplify the impact of the Journal while driving engagement, increasing journal visibility and disseminating content to new audiences globally. Serving as “the front door” to the Journal, this digital evolution represents an important step forward for a field in which advancements in hardware, image processing and clinical evidence have evolved rapidly. However, is social media the panem et circenses of cardiovascular computed tomography (CT), that of superficial appeasement, or of sine qua non; an essential ingredient to the acceleration of the Journal and of the field of cardiovascular CT? This paper aims to present the initial impact of social media within a dedicated cardiovascular CT journal.Percent atheroma volume: Optimal variable to report whole-heart atherosclerotic plaque burden with coronary CTA, the PARADIGM study
Different methodologies to report whole-heart atherosclerotic plaque on coronary computed tomography angiography (CCTA) have been utilized. We examined which of the three commonly used plaque burden definitions was least affected by differences in body surface area (BSA) and sex.Coronary atherosclerosis scoring with semiquantitative CCTA risk scores for prediction of major adverse cardiac events: Propensity score-based analysis of diabetic and non-diabetic patients
We aimed to compare semiquantitative coronary computed tomography angiography (CCTA) risk scores – which score presence, extent, composition, stenosis and/or location of coronary artery disease (CAD) – and their prognostic value between patients with and without diabetes mellitus (DM). Risk scores derived from general chest-pain populations are often challenging to apply in DM patients, because of numerous confounders.A cross-sectional survey of coronary plaque composition in individuals on non-statin lipid lowering drug therapies and undergoing coronary computed tomography angiography
Non-statin therapy (NST) is used as second-line treatment when statin monotherapy is inadequate or poorly tolerated.Rationale and design of the coronary artery calcium consortium: A multicenter cohort study
Although coronary artery calcium (CAC) has been investigated for over two decades, there is very limited data on the association of CAC with cause of death. The CAC Consortium is a large ongoing multi-center observational cohort of individuals who underwent non-contrast cardiac-gated CAC testing and systematic, prospective, long-term follow-up for mortality with ascertainment of cause of death.
