The relationship between quantitative epicardial adipose tissue based on CT and coronary artery disease: A protocol for systematic review and meta-analysis.

Background: Epicardial adipose tissue (EAT) is a kind of visceral adipose tissue with close proximity to coronary artery and myocardium, which can secrete cell factor, and influence the physiological function and pathophysiological process of myocardium and coronary artery. Clinical imaging diagnosis showed that the volume and thickness of EAT exists a certain relevance with coronary artery disease, but it lacked evidence of evidence-based medicine. The research on the implementation of this program will systematically evaluate the relationship of computed tomography (CT) quantitative EAT and coronary artery disease.

Application of Computed Tomography Scan Combined with Electrocardiographic Gating in Hypertensive Patients with Brain and Nerve Diseases.

In this paper, 64-slice spiral computed tomography (CT) retrospective electrocardiographic (ECG) gating technology was used to perform coronary CT angiography scans. The aorta and aortic pulmonary artery diameter were measured quantitatively in healthy people and patients with hypertension and cerebrovascular disease. Corresponding aortic pulmonary artery ratios were obtained through calculation, and the changes of aortic diameter, aortic pulmonary artery ratio, and aortic diameter difference between different cardiac phases, ages, sexes, and levels of hypertension were discussed.
