Expression of the 10 differentially expressed miRNAs in patients with CHD and hyperglycemia split into two groups according to SYNTAX score. (A) RT-qPCR analysis of the expression levels of hsa-let-7b-5p, hsa-miR-4313, hsa-miR-4665-3p and hsa-miR-940 in 22 patients with low SYNTAX score and 53 patients with high SYNTAX score. (B) RT-qPCR analysis of the expression levels of hsa-miR-4459, hsa-miR-4687-3p, hsa-miR-6087, hsa-miR-6089, hsa-miR-6740-5p and hsa-miR-6800-5p in 22 patients with low SYNTAX score and 53 patients with high SYNTAX score. Data are presented as box and whisker plots with the minimum, median and maximum values. *P<0.05, ***P<0.001 vs. low SYNTAX score. CHD, coronary heart disease; miRNA/miR, microRNA; RT-qPCR, reverse transcription-quantitative PCR; SYNTAX, Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery.
