Research Article: Correlation Analysis and Diagnostic Value of Serum Homocysteine, Cystatin C and Uric Acid Levels with the Severity of Coronary Artery Stenosis in Patients with Coronary Heart Disease
Abstract:
With the development of an aging population, the incidence of coronary heart disease (CHD) is getting higher and higher and the mortality rate is also showing a trend of increasing year by year, which seriously affects human health. Currently, in terms of the diagnosis of CHD, coronary angiography (CAG) is still the “gold standard.” However, it is an invasive examination with high risks and costs, which is difficult for patients to accept and not available in all hospitals. Considering this condition, a non-invasive method is urgently needed to predict the severity of coronary artery disease with low risk, low cost and easy operations, especially for those hospitals that cannot perform CAG. In the past few decades, many studies have been analyzed in order to explore or find one or more widely available and inexpensive biochemical parameters to predict the severity of CHD, such as concentrations of N-terminal pro-brain natriuretic peptide (NT-proBNP), glycemic variability, metabolic syndrome (MS) score, glycated hemoglobin, angiogenin, epicardial adipose tissue, waist–hip ratio, d-dimers, eosinophils count in the peripheral circulation and serum vascular cell adhesion molecule- and even gut microbiota,– which mainly assessed the severity of coronary artery stenosis from AUC and sensitivity, with a lack of specificity. Moreover, for the non-invasive diagnosis of CHD, there are also some studies, based on the correlation between the two variables, which have some limitations; these have shown that serum Hcy, Cys C and UA levels are positively correlated with the severity of coronary artery disease, respectively.– While considering that Hcy, Cys C and UA are all involved in the formation of atherosclerosis by affecting endothelial function, implying that they are interconnected and have a close and mutual influence on pathophysiological mechanisms, there are some limitations.– Therefore, how to assess their clinically diagnostic value of CHD overall, such as the AUC, sensitivity, specificity and the Youden index, has not been reported and there is also no definite conclusion on combining the three to predict the diagnostic value of the severity of coronary artery stenosis.
