Predictors of No-Reflow Phenomenon in ST-Elevation Myocardial Infarction Patients Undergoing Primary Percutaneous Coronary Intervention

Abstract

ABSTRACT However, CRP [median (IQR) of 75.08 ± 19.59 in the no-reflow group vs 75.56 ± 15.57 in the reflow group with a value P < 0.001], albumin [median ± SD was 3.58 ± 0.38 g/dL vs 4.00 ± 0.35 g/dL, P < 0.001], monocytes [2.44 ± 0.71 10^3/uL vs 0.38 ± 0.16 10^3/uL, P < 0.001], CAR [median (IQR) of 7.17 (5.58 - 16.18) for the no-reflow and 1.62 (1.46 - 2) in the reflow group, P < 0.001] and MHI [median ± SD of 0.07 ± 0.03 vs 0.01 ± 0.01, P < 0.001] all showed positive correlations with the occurrence of no-reflow. According to our multivariate analysis, CAR had the best predictive value for no-reflow, Odds ratio: 0.182, P < 0.001. It was also suggested the best cut-off value over which risk of no-reflow was high is >3.26 for CAR with AUC = 0.974, making it the most useful laboratory parameter for the prediction of no-reflow in STEMI patients undergoing primary PCI.
