Differentially expressed proteins in CHD patients identified by iTRAQ.

Coverage (%): The number of matching amino acids from peptides divided by the total number of amino acids in the sequence, expressed as a percentage; P values were calculated by comparing the probability of iTRAQ ratio from each group by the Maxquant software, a professional software tool for MS analysis. A P<0.05 indicates the protein in CHD group was significantly changed compared to the controls.
