摘要

To evaluate the feasibility and safety of distal protection device (PercuSurge) during percutaneous coronary intervention (PCI) in patients with acute coronary syndrome. Methods From October 2004 to August 2007, 40 patients with high risk acute coronary syndrome who received primary coronary intervention were included in this study.Patients were divided into two groups according to whether PercuSurge was attempted during PCI. The basic clinical characteristics, angiographic results, and follow-up data before discharge were compared. Coronary arteries blood flow thrombolysis in myocardial infarction (TIMI) grade, TIMI myocardial perfusion (TMP) grade and the rate of no-reflow were performed in all cases after PCI. Results There was no significant difference between the two groups in basic clinical characteristics and angiography before PCI ( P ＞ 0. 05 ). All patients underwent PCI successfully in both groups. In the PercuSurge group, PCI with PercuSurge guardwire protection was performed successfully in 18 patients.There was significant difference between the two groups in TIMI 3 flows gained in target vessels after PCI. Better percentage of TMP grade 3 of target vessels was achieved in PercuSurge group. Less no-reflow were found in PercuSurge group. There were lower peak troponin I and serum MB isoenzyme of creatine kinase levels, higher left ventricular ejection fraction and smaller left ventricular end-diastolic dimension in the PercuSurge group after PCI at the date before discharge (P＜ 0. 05 ). There was no major adverse cardiac events in PercuSurge group, only one patient died in the control group. Conclusions This study demonstrates that using the PercuSurge Guardwire system during PCI in high risk acute coronary syndrome patients to prevent no-reflow is feasibility and safety.
