The average time between CMR scans was 14±4 months. In LGE-matching regions, T2m was significantly higher in LGE+ scans compared to LGE= (62ms vs 56ms, p=0.03), and ILB T2m was higher in LGE+ than LGE- (56ms vs 50ms, p=0.007). No other significant differences were observed.</p><p><strong>Conclusion: </strong>In AFD patients, we demonstrated an association between myocardial inflammation and LGE expansion, with T2m potentially serving as an early marker of disease activity.

With 57 cardiovascular aging biomarkers, the CatBoost model performed best on the test dataset (Pearson r = 0.75; mean absolute error = 3.88 years). CardioAG was independently associated with hypertension, stroke, atrial fibrillation, coronary artery disease, and composite major adverse cardiovascular event (MACE, hazard ratio = 1.08, 95% CI, 1.06-1.10). Incremental and ablation analyses demonstrated complementary contributions across imaging and functional modalities, with multimodal integration enhancing predictive accuracy and providing independent prognostic value for MACE. WGS analysis identified novel common genetic variants associated with interindividual variability in CardioAG, including RN7SKP155, SVIL, and CBFA2T3, highlighting genetic contributions to vascular remodeling, electrophysiological and hemodynamic regulation, and cardiovascular functional reserve.
