NCT05623995

Brief Summary

The purpose of this study is to evaluate the effect of proprotein convertase subtilisin/kexin type-9 (PCSK9) inhibitors added to regular statin therapy on target lesion failure (TLF) and arteriosclerosis progression in patients with chronic total occlusions (CTOs) undergoing successful percutaneous coronary intervention (PCI).
