Updated on 24 January 2021


Objectives: The present study aimed to investigate the difference in late luminal loss (LLL) at 9-month after drug-coated balloon (DCB) treatment with intravascular ultrasound (IVUS) versus angiography for ST-segment elevated myocardial infarction STEMIpatients.

Background: In primary percutaneous coronary intervention for STEMI, DCB angioplasty has proved to be a safe and feasible strategy. Compare with angiography guidance, IVUS-guided PCI significantly improve clinical outcome. With IVUS guidance, STEMI patients undergo DCB angioplasty might have be beneficial results.

Methods: A total of 208 STEMI patients who required DCB treatment were randomly assigned either an IVUS guidance and angiography guidance group. The primary endpoint was late luminal loss at 9-month. Stent thrombosis (ST) was the safety endpoint.
