Coronary computed tomography angiography (CCTA) not only provides information regarding luminal stenoses but also allows for visualization of mural atheromatous changes (coronary plaques).We sought to elucidate whether plaques seen on CCTA enable prediction 2-year outcomes in patients with suspected and known coronary artery disease (CAD).Of 3015 who underwent CCTA, the images clinical courses 2802 were independently analyzed. The primary endpoint was composite all-cause death acute...
Tumor necrosis factor (TNF)-α reportedly has key pro-inflammatory properties in both atherosclerosis and adipocytes. To further investigate the biologic impact of epicardial adipose tissue (EAT) on coronary atherosclerosis, we evaluated relationship between TNF-α gene expression EAT clinically-assessed computed tomography (CT).We studied 47 patients before cardiac surgery (coronary artery bypass grafting [CABG], n=26; non-CABG, n=21), assessing visceral (VAT) area, volume, calcium score...
The purpose of our study was to compare the diagnostic performance coronary CT angiography (CTA) subjected model-based iterative reconstruction (IR) or hybrid IR rule out in-stent restenosis.We enrolled 16 patients who harboured 22 stents. They underwent CTA on a 320-slice scanner. images were reconstructed with (AIDR 3D) and (FIRST) algorithms. We calculated stent lumen attenuation increase ratio measured visible diameter. Two blinded observers visually graded likelihood restenosis (lesions...
Although the coronary artery calcium score (CACS) is a prognostic measurement in asymptomatic individuals, it measured symptomatic patients using computed tomography angiography (CCTA). We aimed to examine predictive value of CACS for mid- long-term cardiovascular mortality and morbidity who underwent CCTA.
It has been shown in several studies that coronary artery calcium (CAC) burden or CAC progression is associated with heart failure. We tested the hypothesis extent of left ventricular (LV) diastolic parameters derived from gated myocardial perfusion single-photon emission computed tomography (SPECT) patients no evidence ischemia.
This article contains the data showing illustrative examples of plaque classification on coronary computed tomography angiography (CCTA) and measurement 18F-sodium fluoride (18F-NaF) uptake in atherosclerotic lesions positron emission (PET). We divided into one three types CCTA (calcified plaque, non-calcified partially calcified plaque). Focal 18F-NaF each lesion was quantified using maximum tissue-to-background ratio. also provides a representative case with detected identified...
This article contains the data regarding clinically-assessed visceral adipose tissue (VAT) area and epicardial (EAT) volume on computed tomography (CT) images EAT pathology, represented by inflammation neoangiogenesis, complementing reported Kitagawa et al. [1]. In 45 patients scheduled for cardiac surgery, we studied CT obtained prior to surgery numbers of CD68+ individual macrophages CD31+ neovessels in samples subsequently during surgery. The revealed a moderate correlation between VAT...
Background: Previous studies indicate that epicardial adipose tissue (EAT) biologically contributes to coronary atherosclerosis progression. The inflammation and neoangiogenesis have been reported be biological markers of ‘diseased’ tissues. We evaluated the relation EAT pathologies, represented by neoangiogenesis, computed tomography (CT)-based atherosclerosis. Methods: enrolled 45 patients undergoing cardiac CT examination before elective surgery (coronary artery bypass graft [CABG], n =...
Background: Arterial 18 F-sodium fluoride ( F-NaF) uptake on positron emission tomography (PET) has been reported to reflect active atherosclerosis with osteogenesis and inflammatory stimulus. We evaluated the relation of F-NaF computed (CT)-based coronary atherosclerosis. Methods: enrolled 25 patients ≥1 atherosclerotic lesions detected cardiac CT, who underwent PET/CT. Each lesion was luminal stenosis plaque types (calcium = CP, non-calcified NCP, partially calcified PCP) CT angiography....
