BACKGROUND No-reflow phenomenon is a well-known problem, often accompanying percutaneous coronary intervention (PCI) for ST-segment elevation acute myocardial infarction (STEAMI). This study investigated the value of plasma D-dimer and Endothelin-1 (ET-1) levels on admission in predicting no-reflow after primary PCI and long-term prognosis in STEAMI patients with type 2 diabetes mellitus (T2DM). MATERIAL AND METHODS There were 822 patients with STEAMI and T2DM undergoing successful primary PCI included in this study: 418 patients showed normal re-flow after PCI, while 404 patients showed no-reflow phenomenon after PCI. The predictive value of plasma ET-1 and D-dimer level, and other clinical parameters for the no-reflow phenomenon were analyzed. RESULTS The high plasma ET-1 and D-dimer levels showed predictive value for the no-reflow phenomenon in STEAMI patients with T2DM. Patients with high D-dimer and ET-1 levels showed higher risk (4.212, with 95%CI of 2.973-5.967 and 2.447 with 95%CI of 1.723-3.476, respectively) of no-reflow phenomenon compared with patients with low plasma D-dimer and ET-1 levels. Sensitivity of high plasma ET-1 and D-dimer levels in predicting no-reflow was 0.766. Both plasma D-dimer and ET-1 were adverse prognosticators for STEAMI patients with a T2DM post PCI (P<0.001). CONCLUSIONS In conclusion, plasma D-dimer and ET-1 levels on admission independently predict no-reflow after PCI in STEAMI patients with T2DM. When combined, the D-dimer and ET-1 levels as predictive and prognostic values are clinically promising. The plasma D-dimer and ET-1 levels provided a novel marker for treatment selection for the STEAIM patients with a T2DM history.
