背景:经皮冠状动脉介入(PCI)时,冠状动脉内多普勒导丝可实时检测并定量微栓塞。本研究旨在探讨行择期PCI时,多普勒检出微栓塞的频率是否与肌坏死发生率相关。方法和结果:研究对象为52例连续的冠状动脉
BACKGROUND: Percutaneous coronary intervention (PCI) allows the intracoronary Doppler guidewire to detect and quantify micro-embolism in real time. The purpose of this study was to investigate whether Doppler detection of micro-embolism is associated with a significant incidence of muscle necrosis during PCI. Methods and Results: The study consisted of 52 consecutive coronary arteries
