The PIANO score ranged from 0 to 14 points, yielding a concordance index of 0.857 (95% confidence interval 0.833 to 0.88, with good calibration. In the high-risk (≥8 points) group, the probability of angiographic no-reflow phenomenon was 38.7%, while it was only 4.8% in the low-risk (8 points) group. The score system performed well in the validation set. We establish and validate a score system based on six clinical variables to predict angiographic no-reflow in STEMI patients undergoing primary PCI, which may help choo
