Abstract:
Objective Aim To investigate the effects of high-burden thrombus on outcomes of emergency percutaneous coronary intervention(PCI)in elderly patients with acute myocardial infarction.Methods Seventy-three elderly patients with ST elevated acute myocardial infarction(STEAMI)within 12 hours from onset received emergency PCI.They were divided into the high-burdern thrombus group(n=26)and the low-burden thrombus group(n=47)according to coronary artery angiography result.Mortality of 30 days,peak value of CK-MB,ejection fraction(EF)and TIMI flow after PCI were compared.Results The occurance of high-burden thrombus in infarct-related arteries was 35.6% which was more often common in right coronary artery.The rate of TIMI3 flow after PCI in high-burden thrombus group was lower than that of the low-burdn thrombus group.The 30-day-mortality and peak CM-MB level in the high-burden thrombus group was higher than that of the low-burden thrombus group.Conclusion High burden thrombus is an important factor of prognosis in elderly patients with acute myocardial infarction after emergency PCI.
