Background: No-reflow phenomenon is one of the major complications and may be associated with adverse outcomes of patients with ST-segment Elevation Myocardial Infarction (STEMI) undergoing Primary Percutaneous Coronary Intervention (PPCI).

Objective: To detect the prevalence and predictive factors of the no-reflow phenomenon in patients with STEMI undergoing PPCI.

Result: The prevalence of no-reflow is 17.6%. Predictors of the no-reflow phenomenon are thrombus burden ≥ 4(OR=10.37, CI 95% 3.27-32.83, p<0.001), Killip 3-4 at admission (OR=8.17, CI 95% 1.3-51.5, p=0.025), time from symptom onset to PPCI (OR=4.37, CI 95% 1.54-12.37, p=0.005), lesion length (OR=1.12, CI 95% 1.02-1.22, P=0.016).

Conclusion: No-reflow phenomenon after PPCI can be predicted with clinical and angiographic features.
