Objective: To study the interaction effects of rs10757278 polymorphisms at 9p21 locus and traditional risk factors on coronary heart disease (CHD) in Xinjiang, China. Methods: This case–control study consecutively enrolled 310 unrelated consecutive CHD patients aged 18–70 years old. All study participants were recruited between January and December 2017 from The Heart Center of The First Affiliated Hospital of Xinjiang Medical University. CHD patients were confirmed by coronary angiography (≥50% diameter stenosis in at least one of the major coronary arteries) according to the American Heart Association...

This study aims to compare the performance of 16 cm wide-coverage detector CT (WDCT) using the snapshot freeze technique with a new-generation dual-source CT (DSCT) with 66 ms temporal resolution for CCTA. METHODS: Total 101 patients with suspected coronary heart disease were enrolled. Of these, 50 and 51 patients were examined on WDCT and DSCT, respectively. CT values, image noise, signal-to-noise ratio, and contrast-to-noise ratio were measured. The image processing efficiency was recorded, followed by statistical comparison of diagnostic accuracy and radiation dose. RESULTS: Ninety-nine patients (98.02%) had...

Abstract OBJECTIVE: To analyze the correlation of annexin A2 with coronary atherosclerotic heart disease (CAD) and the severity of CAD. METHODS: We collected data from a total of 200 inpatients admitted in our department between August, 2017 and August, 2019. According to the. RESULTS: of coronary angiography, the patients were divided into CAD group (n=150) and non-CAD (n=50), and the CAD patients was further divided, according to their clinical stability, into stable angina (SAP) group and acute coronary syndrome (ACS) group. Serum levels of annexin A2, MPO and PON1 were detected in all these patients,...

AbstractCoronary artery bypass grafting (CABG) is one of the most common procedures in the United States as many Americans suffer from coronary heart disease and undergo CABG each year. While CABG has been performed for decades, questions remain regarding the benefits graft marker placement provides for patient therapy and outcomes. Markers at the proximal graft anastomosis aim to improve the efficiency and reduce the risks of subsequent, post-coronary artery bypass grafting coronary angiography by decreasing fluoroscopy time and contrast volume used. Graft markers have been shown to reduce fluoroscopy time and contrast vo...

Conclusions: High-grade NAFLD is more present in symptomatic CHD. The higher degree of liver stiffness in patients with NAFLD, the higher risk of CHD in these NAFLD patients.

Abstract OBJECTIVE: We sought to distinguish lipid plaques using a CT quantitative pixel density histogram, based on the pathological diagnosis of lipid cores as the gold standard. MATERIALS AND METHODS: Eight patients awaiting heart transplantation due to end-stage coronary heart disease underwent coronary CT angiography (CCTA) spectroscopy prior to heart transplantation; coronary artery pathological analysis was performed for all patients. Lipid-core plaques were defined pathologically as manifesting a lipid core diameter> 200 μm, a circumference> 60 degrees, and a cap thickness

In this study, we propose an integrated method using machine learning. The machine learning methods of random trees (RTs), decision tree of C5.0, support vector machine (SVM), and decision tree of Chi-squared automatic interaction detection (CHAID) are used in this study. The proposed method shows promising results and the study confirms that the RTs model outperforms other models.
