Summary: This study developed and validated machine learning models to predict hidden coronary artery disease (CAD) and assess long-term outcomes in patients with acute ischemic stroke. The results showed that machine learning may help identify CAD and that long-term outcomes are associated with the prediction results.

Summary: Recent studies have found that high volumes of physical activity in older male endurance athletes are associated with increased levels of coronary artery calcification (CAC), although the exact mechanisms are still not well understood. Possible mechanisms include increased exposure to inflammatory cytokines, reactive oxygen species, and oxidized low-density lipoproteins. Other factors such as elevated circulating parathyroid hormone and long-term exposure to non-laminar blood flow in individuals with pre-existing atherosclerosis during strenuous physical activity may also contribute to the increased calcification. Furthermore, the role of testosterone in this process remains uncertain. This review discusses the association between high-volume endurance exercise and CAC in older men, explores potential mechanisms, and provides clinical implications and recommendations for those at risk.

Summary: Fractional flow reserve and plaque progression assessed by serial coronary CT angiography predicted the risk of future major adverse cardiovascular events (MACE), demonstrating better accuracy compared to traditional assessment markers.

Summary: The presence of nonobstructive and obstructive CAD on CCTA is associated with an increased risk of coronary events, with patients having nonobstructive CAD showing a 2-fold increase in risk compared to those with no CAD.

Summary: Recent studies have shown that there is a relationship between wide left coronary artery bifurcation angle (LAD-LCx) and coronary artery disease (CAD). Current evidence suggests that individuals with a wider LAD-LCx angle experience altered blood flow dynamics at the bifurcation site, which may increase the risk of developing CAD. However, further research is needed to confirm the causal relationship between LAD-LCx angle and CAD risk factors.

Summary: Coronary artery calcium (CAC) is a direct measure of an individual's coronary atherosclerotic burden. Higher levels of CAC are strongly associated with an increased risk of cardiovascular disease (CVD) events and individuals with very high CAC levels have a CVD risk similar to stable persons with a prior CVD event. Conversely, the absence of CAC (CAC=0) is associated with a low long-term risk of CVD, even among groups classified as high risk based on traditional risk factors.

Summary: This study found that noncalcified plaque volume is mainly influenced by environmental factors, while coronary artery calcification score and calcified plaque volume are more determined by genetics. This emphasizes the importance of early lifestyle interventions in preventing coronary plaque formation.

Summary: The study found that calcified plaque volume is closely related to the progression of coronary artery disease, but this association becomes negative after accounting for baseline plaque volume. Conversely, the percentage of calcified plaque volume is an independent predictor of plaque volume reduction. High CPV is associated with major adverse cardiac events, while high PCPV is inversely related to adverse cardiac events.

Summary: In non-obstructive coronary artery disease, the decline of CT-derived fractional flow reserve (FFRCT) depends not only on vessel length but also on the lumen volume. A new marker, the ratio of lumen volume to vessel length (V/L ratio), was found to be the strongest predictor of distal FFRCT.

Summary: By analyzing clinical data and CCTA images of 400 patients, it was found that FAI and NCPB were independent risk factors for coronary plaque progression. Combining conventional parameters with radiomics features derived from CCTA can better predict plaque progression.

Summary: This study developed a risk prediction model for patients with nonobstructive CAD and found that advanced coronary plaque features have incremental value in discriminating clinical events in low-risk stable chest pain patients. ASCVD risk, degree of stenosis, and presence of HRP features independently predicted composite events in patients with nonobstructive CAD, improving model fit significantly. Patients with ASCVD >= 7.5%, any HRP, and mild/moderate stenosis had significantly higher rates of events compared to those who did not meet those criteria.

Summary: Abnormal LV geometry is associated with a worse prognosis in individuals with no or nonobstructive CAD, suggesting that LV geometry assessment can improve risk stratification in these patients.

Summary: Coronary artery calcification is a useful indicator for assessing the risk of coronary artery disease and determining the need for statin therapy in high-risk patients. CACS can be detected and quantified within seconds, aiding in a more accurate assessment of the risk in patients with atherosclerotic cardiovascular disease.
