Abstract:
Objective: To explore the influencing factors of slow blood flow phenomenon after emergency percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Methods: Clinical and PCI angiographic data of 488 patients, who were diagnosed as AMI and received primary PCI in our hospital from Jan 2010 to Jun 2011, were retrospectively analyzed. Patients were divided into slow blood flow group (n=51, TIMI flow ≤ grade 2) and normal flow group (n=437, TIMI flow= grade 3). Their clinical characteristics between two groups were compared. Results: Compared with normal flow group, there were significant reductions in percentages of thrombus aspiration (75.3% vs. 60.8%) and application of platelet glycoprotein IIb/IIIa receptor antagonist (81.7% vs. 68.6%) during PCI, and significant rise in total length of implanted stents [(31.8±12.2) mm vs. (35.7±12.0) mm] in slow blood flow group, P<0.05 all. Multi-factor Logistic regression analysis indicated that percentages of thrombus aspiration during PCI and total length of stents were independent influencing factors for slow blood flow (P<0.05 both). Conclusion: Percentages of thrombus aspiration and total length of stents during PCI are independent influencing factors for slow blood flow.
