Background: Perivascular adipose tissue (PVAT) attenuation has emerged as a novel biomarker for identifying high-risk arterial plaques due to its association with inflammation. Recognizing the systemic nature of atherosclerosis and link major cardiovascular events in coronary disease, this study evaluated PVAT peripheral arteries using CT imaging expand understanding diagnostic prognostic potential. Methods: retrospective analysis 53 consecutive patients who underwent angiography, examining density across five primary segments. A 5 mm region interest adjacent vascular wall was analyzed by two blinded readers, reproducibility coefficients calculated determine reliability measurements. For statistical analyses, mean values were derived from these The stratified into four groups based on degree stenosis: <25%, 25–50%, 50–70%, >70%. comparisons between performed Kruskal–Wallis test pairwise Mann–Whitney U Holm–Bonferroni correction multiple comparisons. Results: revealed statistically significant disparities categorically differentiated stenosis (p < 0.001), indicating an severity. This especially pronounced external iliac, common femoral, superficial popliteal arteries, where p-values consistently below 0.05. Subsequent analyses utilizing affirmed findings, particular femoral 0.05). Conclusions: our findings reinforce correlation increased stenosis, supporting clinical value non-invasive risk stratification potentially guiding therapeutic interventions.

The inclusion criteria (1) studies measuring of adult patients at baseline (2) reporting follow-up data interest. primary outcome was major adverse events. Secondary included cardiac death, myocardial infarction, coronary revascularization, atrial fibrillation.Twenty-nine published 2012 2022, comprising 19 709 patients, in our analysis.

Accumulating evidence suggests that ectopic/visceral adiposity may play a key role in the pathogenesis of nonischaemic cardiovascular diseases associated with type 2 diabetes. Epicardial adipose tissue (EAT) is complex visceral fat depot, covering 80% cardiac surface anatomical and functional contiguity to myocardium coronary arteries. EAT interacts biology underlying by secreting wide range adipokines. Magnetic resonance imaging (MRI) reference modality for structural heart. The technique now also emerging as quantification. With this narrative review, we (a) surveyed contemporary clinical studies utilized MRI characterize (studies published 2010–2023); (b) listed trials monitoring response treatment size well myocardial parameters (c) discussed potential pathophysiological development diabetic cardiomyopathy.
