We performed miRNA microarray analysis from the plasma of three CAD patients and three healthy controls. 
miRNA microarray analysis
Subsequently, we performed quantitative real-time PCR (qRT-PCR) analysis of miRNA expression in plasma of another 67 CAD patients and 67 healthy controls.

The receiver operating characteristic (ROC) curves indicated these two miRNAs had great potential to provide sensitive and specific diagnostic value for CAD.
