Abstract: 【Objective】 To investigate the correlation of coronary slow flow (CSF) between the plasma levels of adiponectin (APN) and medullary peroxidase (MPO). 【Methods】 The study population were consisted of 50 SCF patients and 50 normal controls

without coronary artery stenosis by coronary angiography (CAG) . Coronary flow rates were documented by TIMI frame count (TFC). Plasma levels of adiponectin(APN)

myeloperoxidase(MPO) and other blood biochemical index were obtained in all participants

and analysis of the difference between the two groups

logistic regression analysis was used to screen the risk factors of coronary slow flow. 【Results】 MPO levels of the CSF patients were significantly higher (93.70 ± 37.75 vs 26.76 ± 6.20 ng/mL

P < 0.001)

but the APN concentrations were lower than control group (4.06 ± 0.20 vs 8.78 ± 0.75 mg/mL

P < 0.001)

there difference was statistically significant (P < 0.05); Logistic regression analysis show that high plasma MPO levels (OR = 1.23

P = 0.001)

and low concentrations of APN were related to CSF (OR = 0.92

P = 0.040). 【Conclusion】 The levels of plasma MPO and APN were closely related to coronary slow flow

can be used as a predictive indicator of coronary slow flow.
