title: Effect of Collateral Circulation on Left Ventricular Systolic Function in Patients with Totally Occluded Artery Undergoing PCI
abstract: Background: Over the past three decades, accumulating evidence has documented that pre-existing welldeveloped CCC at the onset of acute myocardial infarction plays an important role in preserving left ventricular function, reducing infarct size, preventing left ventricular aneurysm formation, and survival. Objective: The aim of this study is to evaluate the effect of collateral circulation as measured by Rentrop score on left ventricular regional and global systolic function in patients with tot
