Comparison of outcomes of percutaneous coronary intervention on proximal versus non-proximal left anterior descending coronary artery proximal left circumflex and proximal right coronary artery: A cross-sectional study

摘要

BackgroundPrevious studies have shown that lesions in proximal left anterior descending coronary artery (LAD) may develop more restenosis after balloon angioplasty than lesions in other coronary segments. However, stenting seems to have reduced this gap. In this study, we compared outcomes of percutaneous coronary intervention (PCI) on proximal LAD versus proximal left circumflex (LCX) or right coronary artery (RCA) and proximal versus non-proximal LAD.
