This study aimed to investigate the potential of microRNA (miR)-146a and miR-146b for predicting restenosis and rapid angiographic stenotic progression (RASP) risk in coronary heart disease (CHD) patients who underwent percutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation. In total, 255 CHD patients who underwent PCI with DES were enrolled, and their baseline, procedural, and post procedure characteristics were recorded. Plasma samples were obtained before PCI treatment to detect the miR-146a and miR-146b expression by reverse transcription quantitative polymerase chain reaction. Besides, restenosis and RASP occurrences were assessed based on coronary angiograms at 12 months after the surgery. The occurrence rates of restenosis and RASP were 9.0% and 32.9% respectively in CHD patients who underwent PCI with DES. Furthermore, miR-146a and miR-146b expressions were elevated in CHD patients with restenosis compared with CHD patients without restenosis. Subsequent receiver operating characteristic (ROC) curve analysis showed that miR-146a (area under the curve (AUC), 0.674; 95% CI, 0.567-0.781) and miR-146b (AUC, 0.801; 95% CI, 0.729-0.875) could predict increased restenosis risk, among which miR-146b numerically exhibited a better predictive value for higher restenosis risk. Besides, miR-146a and miR-146b expressions were raised in CHD patients with RASP compared with CHD patients without RASP. Followed ROC curve analysis illuminated that miR-146a (AUC, 0.772; 95% CI, 0.714-0.829) and miR-146b (AUC, 0.706; 95% CI, 0.644-0.769) presented similar values in predicting elevated RASP risk. miR-146a and miR-146b predict increased restenosis and RASP risk in CHD patients who underwent PCI with DES.
