The rs2910164 polymorphism of microRNA-146a-particularly genotypes carrying the G allele-along with a history of diabetes mellitus, dyslipidemia, smoking, NT-proBNP ≥ 300 pg/mL, a GRACE score > 140, and a TIMI score > 4 were identified as independent predictors of severe coronary artery stenosis. Here, NPPB is linked to coronary stenosis.
