Inadequate expansion of coronary stents is associated with stent thrombosis in early stage and with stent restenosis in later stages. Postdilatation (postD) performed using non-compliant balloons improves stent expansion. However, use of this ballooning strategy in primary percutaneous coronary intervention (PPCI) has not been evaluated adequately. Patients who presented with ST segment elevation myocardial infarction (STEMI) and underwent PPCI were included in the present study. Patients were randomized into two groups as those for whom postD was performed (n=62) and those for whom postD was not performed (n=62). Coronary blood flow was evaluated using the thrombolysis in myocardial infarction (TIMI) flow and TIMI frame count (TFC). Total of 124 patients with STEMI were included in the study. There was no difference with respect to baseline TIMI flow, culprit coronary artery and MI localization. However, slow-reflow rate (14.5% vs 35.5%, p=0.007) and final corrected TFC (28.9±16.9 vs 37.0±23.1, p=0.028) were significantly higher in the postD group. Multivariate regression analysis showed postD as an independent variable for slow reflow (OR 11.566, 95% CI 1.633 to 81.908, p=0.014). In our study, routine postD during PPCI was found to be associated with an increased risk of slow reflow in patients without angiographic stent expansion problems.

Abstract Background: The no-reflow phenomenon (NRP) is an important factor affecting the prognosis of patients with acute myocardial infarction undergoing primary percutaneous coronary intervention (PPCI). This study aims to investigate the association of circulating miR-660-5p with NRP in patients with ST segment elevation myocardial infarction (STEMI) undergoing PPCI.Methods: Consecutive patients diagnosed with anterior STEMI within 12 h of pain onset were included in the study; in these patients, coronary angiography confirmed that the infarct-related artery was the left anterior descending (LAD) artery. Angiographic NRP was defined as a final TIMI flow of 2 or a final TIMI flow of 3 with a myocardial blush grade (MBG) < 2. High miR-660-5p was defined as a value in the third tertile. The relationship of circulating miR-660-5p with NRP was assessed using Spearman correlation analysis and multiple linear regression analysis.Results: Fifty-two eligible patients were finally included in this study (mean age: 56±12.4 years, >65 years: 53.8%, male: 76.9%, and mean BMI: 26.3±3.5). The incidence of NRP was 38.5%. Circulating miR-660-5p was significantly related to the mean platelet volume (MPV). Patients were divided into tertiles by miR-660-5p levels (Q1: ≤ 7.18, Q2: 7.18-11.31, Q3: > 11.31). Patients in the high microRNA-660-5p group had almost a 6-fold higher risk of NRP than those in the low microRNA-660-5p group [(odds ratio (OR)=5.68, 95% confidence interval (CI) 1.40-23.07, p=0.015). When analysed by tertiles, consistent trends of an increasing relative odds of NRP were reported (OR1 for Q2 VS. Q1: 1.25, 95% CI: 0.27-5.73, p=0.77; OR2 for Q3 VS. Q1: 5.96, 95% CI: 1.33-26.66, p=0.02), even after multivariable adjustment. Receiver operating characteristic curve analysis demonstrated that the microRNA-660-5p level of 10.17 was the best cut-off level to predict the incidence of the no-reflow phenomenon in patients undergoing primary percutaneous coronary intervention with an area under the curve (AUC) of 0.768 (95% CI: 0.636-0.890).Conclusion: Circulating miR-660-5p was significantly associated with NRP, and it may be a useful biomarker to predict the incidence of NRP in patients with STEMI undergoing PPCI.

Abstract Background No-reflow phenomenon (NRP) is an important factor affecting the prognosis of patients with acute myocardial infarction undergoing primary percutaneous coronary intervention (PPCI). This study aims to investigate the association of circulating miR-660-5p with NRP in ST segment elevation myocardial infarction (STEMI) undergoing PPCI. Methods 52 eligible consecutive patients diagnosed with anterior STEMI within 12h of pain onset, which coronary angiography confirms that infarct-related artery is left anterior descending artery (LAD), were included in this study. Angiographic NRP is define as the final TIMI flow of 2 or the final TIMI flow of 3 with myocardial blush grade (MBG) of <2.Effect of circulating miR-660-5p on NRP was assessed using Spearman correlation analysis and multiple linear regression analysis. Results The incidence of NRP was 38.5%. Patients with higher miR-660-5p levels have significantly higher incidence of coronary NRP. At multivariable analysis, circulating miR-660-5p remained an independent predictor of NRP (odds ratio [OR]=1.34, 95%CI 1.10 to 1.63, p=0.004). Patients in higher microRNA-660-5p levels group have almost a 6-fold higher risk of NRP than that in lower microRNA-660-5p group (OR=5.68, 95%CI 1.40 to 23.07, p=0.015). When analyzed by tertiles, consistent trends of increasing relative odds of NRP were reported (OR1 for Q2 VS. Q1: 1.25,95%CI: 0.27-5.73, p=0.77;OR2 for Q3 VS. Q1: 5.96,95%CI: 1.33-26.66, p=0.02). Circulating miR-660-5p was related to MPV significantly. Conclusion Circulating miR-660-5p is an independent predictor of NRP in STEMI patients undergoing PPCI.
