Objective: To evaluate the value of epicardial adipose tissue (EAT) thickness combined with serum ischemic modified albumin (IMA) concentration in the diagnosis of coronary heart disease.
Methods: A total of 180 patients with coronary heart disease from May 2017 to December 2018 were selected as the case group. After the examination of Judkins coronary angiography, they were grouped according to the results of angiography, including 60 patients in a single-vessel group, 60 patients in a double-vessel group, and 60 patients in a multi-vessel group. Sixty healthy people with physical examinations at our hospital at the same time were selected as the control group. All selected participants were tested for epicardial adipose tissue thickness by echocardiography and serum IMA concentration by albumin cobalt ion binding test.
Results: The EAT thickness and IMA concentration in the single-vessel disease group, double-vessel disease group, and multi-vessel disease group significantly were higher than those in the control group (P < .01). The ROC curve shows that the sensitivity is 53.33% and the specificity is 87.6%, when the EAT thickness is 6.12 mm. The sensitivity is 76.0% and the specificity is 72.3%, when the serum IMA concentration is 72 U/L. When the two were combined, the sensitivity was 40.15% and the specificity was 96.89%. In the parallel test, the sensitivity was 88.3% and the specificity was 65.44%.
Conclusion: Ultrasound detection of EAT thickness and serum IMA concentration has certain reference value for the diagnosis of coronary heart disease. Combined diagnosis can significantly improve the diagnosis rate and accuracy of coronary heart disease.
