The calcium score may be estimated with a scout scan, and the injection of contrast withheld if it appears that the patient has a prohibitively high calcium score. This allows one to avoid exposing the patient to unnecessary radiation from contrast if it is clear that the patient's calcium sc...
Calcium ScorePlaque BurdenCold Pressor TestCoronary Calcium ScoreIntroduction Coronary endothelial function (CEF) is a prognostic marker that worsens with progression of coronary atherosclerosis. In the past, invasive angiography combined with intra-coronary acetylcholine injection or the cold pressor test (...
Next, we investigated whether there were gross morphological and cellular changes to the His–Purkinje network following MI induced by left anterior descending (LAD) coronary artery ligation. We first analyzed the network structure at 3 d after MI ofCx40eGFP/+regenerative P1 and non-regenerative ...
In mice subjected to myocardial infarction through ligation of the left anterior descending coronary artery (LAD), expression levels of Trdn-AS, cardiac Trdn and the ratio of cardiac and skeletal muscle isoform expression were significantly decreased as compared to sham-operated mice (Fig. 4c–d)...

However, in the highest tertile of calcium score, specificity and positive predictive value of FFRCT were significantly lower than those of first-pass CTP. Accordingly, a combined approach of dynamic CTP imaging and FFRCT has been demonstrated to improve diagnostic performance in detecting functional ...
The catheter coronary angiogram showed chronic total occlusion of the LAD (yellow arrow) and obstructive CAD of the LCx (yellow arrow). Fractional flow reserve measurements of the LCx was 0.69. Post-stenting image in the bottom right shows the re-perfusion of the LAD and expansion of the LCx...

Figure 2. A 57-year-old male patient underwent [68Ga]Ga-FAPI-46 PET/MRI 5 days after acute STEMI, recanalization and implantation of drug-eluting stent to the LAD and recanalization of occluded RCx-RM1 stent. Subendocardial septal to apical LGE (up to 75% transmural) and subendocardial...
(OXPHOS) were downregulated in the BZ of both species, reflecting the metabolic reprogramming of BZ CMs5,21,24,30,38(Extended Data Fig.1a–dand Supplementary Tables3–6). In addition, genes with a role in extracellular matrix remodeling and calcium binding were upregulated in the BZ of ...
