MYOCARDIAL SALVAGE EFFECTS OF PRIMARYANGIOPLASTY UNDER DISTAL PROTECTION IN PATIENTSWITH MYOCARDIAL INFARCTION

摘要

Background: Primary angioplasty under distal protection (DP) is supposed to be useful strategy to obtain optimal rayocardial reperfusion. The aim of this study was to evaluate the beneficial effects of DP. Methods: A total of 47 acute ST-segment elevated myocardial infarction patients were enrolled in this study. Primary angioplasty under DP was performed in 22 cases and primary angioplasty with only thrombectomy device was in 25 cases. The degree of optimal myocardial reperfusion was assessed by early ST-segment resolution (STR) and was compared between 2 groups. Results: Baseline characteristics were not different in both groups. Conclusion: DP group showed greater STR and the improvement of global and segmental LV function in DP group compared to Rescue group. These data may indicate primary angioplasty under DP is more effective strategy to reduce microembolization and salvage LV function.
