ABSTRACT
Coronary heart disease (CHD) is one of the leading causes of heart-associated deaths worldwide. Conventional diagnostic techniques are ineffective and insufficient to diagnose CHD with higher accuracy. To use the circulating microRNAs (miRNAs) as non-invasive, specific and sensitive biomarkers for diagnosing of CHD, 203 patients with CHD and 144 age-matched controls (126 high-risk controls and 18 healthy volunteers) were enrolled in this study. The direct S-Poly(T)Plus method was used to identify novel miRNAs expression profile of CHD patients and to evaluate their clinical diagnostic value. This method is an RNA extraction-free and robust quantification method, which simplifies procedures, reduces variations, in particular increases the accuracy. Twelve differentially expressed miRNAs between CHD patients and high-risk controls were selected, and their performances were evaluated in validation set-1 with 96 plasma samples. Finally, six (miR-15b-5p, miR-29c-3p, miR-199a-3p, miR-320e, miR-361-5p and miR-378b) of these 12 miRNAs were verified in validation set-2 with a sensitivity of 92.8% and a specificity of 89.5%, and the AUC was 0.971 (95% confidence interval, 0.948-0.993, P < .001) in a large cohort for CHD patients diagnosis. Plasma fractionation indicated that only a small amount of miRNAs were assembled into EVs. Direct S-Poly(T)Plus method could be used for disease diagnosis and 12 unique miRNAs could be used for diagnosis of CHD.
