Abstract | BACKGROUND: METHODS: Coronary angiography (CAG) was performed on 58 patients with acute ST-segment elevation myocardial infarction ( STEMI) and TIMI 3 flow after P-PCI (43 men, 15 women; mean age, 55.5 ± 10 years). TIMI 3 flow was achieved either by simple balloon dilatation and/or thrombus aspiration. Lesion length, RVD, minimal lumen diameter (MLD), mean vessel diameter (meanD), and area of stenosis were compared during P-PCI and follow-up CAG. RESULTS: RVD, MLD, and meanD values were significantly higher during the follow-up CAG than after P-PCI (RVD 2.7 ± 0.7 mm vs. 2.9 ± 0.7 mm, p = 0.001; MLD 1.5 ± 0.5 mm vs. 1.7 ± 0.4 mm, p = 0.002; meanD 2.2 ± 0.5 mm vs. 2.4 ± 0.5 mm, p = 0.001). Area of stenosis values were significantly lower during the follow-up CAG than after primary PCI (69.5 ± 16.5 % vs. 62.1 ± 15 %, p = 0.001). Lesion lengths were not statistically significant during the follow-up CAG and primary PCI (lesion length 24.0 ± 10.8 mm vs. 22.1 ± 8.8 mm, p > 0.05). CONCLUSION: This study showed that RVD was higher at the follow-up CAG a few days after AMI in patients who had TIMI 3 flow after P-PCI with simple balloon dilatation and/or thrombus aspiration. A delay of a few days for stent implantation in P-PCI allows for larger-diameter stent use and may help to reduce stent thrombosis and restenosis rates.
