Background Incidental extrapulmonary findings are commonly detected on chest CT scans and can be clinically important. Purpose To integrate artificial intelligence (AI)-based segmentation for multiple structures, coronary artery calcium (CAC), and epicardial adipose tissue with automated feature extraction methods and machine learning to detect extrapulmonary abnormalities and predict all-cause mortality (ACM) in a large multicenter cohort. Materials and Methods In this post hoc analysis, baseline chest CT scans in patients enrolled in the National Lung Screening Trial (NLST) from August 2002 to September 2007 were included from 33 participating sites.

Article Synopsis
- The study aimed to assess how diagnostic cardiovascular procedure volumes rebounded in the U.S. and abroad during the year after COVID-19 hit, relying on data from 669 facilities worldwide.
- In the early pandemic (April 2020), procedure volumes dropped significantly but showed a better recovery in U.S. facilities by April 2021 compared to non-U.S. facilities, although high-income non-U.S. countries showed similar recovery rates as the U.S.
- Regional variations within the U.S. were noted, with the Midwest having the highest recovery rate, but no specific factors were found to predict recovery levels from the initial drop in procedure volumes.

Article Synopsis
- - This study aimed to evaluate how coronary CT angiography (CCTA) and derived fractional flow reserve (FFR) are used clinically to assess coronary artery disease (CAD) in patients with diabetes mellitus (DM) compared to those without DM.
- - The analysis included 4,290 participants and found that patients with DM tended to have more severe CAD conditions, but both groups shared similar rates of treatment changes based on CT-FFR results and coronary revascularization.
- - Ultimately, while DM was linked to higher risk of adverse cardiovascular events over a year, it didn't significantly increase risk when accounting for the severity of arterial blockages.

Article Synopsis
- This study analyzed 5-year data from the CONFIRM registry to assess the impact of baseline aspirin and statin use on mortality and major cardiovascular events in individuals without significant coronary artery blockage.
- Researchers included 6,386 participants, predominantly middle-aged men, focusing on those with nonobstructive coronary artery disease (CAD) and confirmed that this condition increased all-cause mortality risk compared to those with no CAD.
- Results showed that while baseline aspirin use did not significantly lower cardiovascular events or mortality, statin use was linked to a reduced rate of major adverse cardiovascular events on risk-adjusted analysis.
