研究问题
Given the limitations of the study, including the limited sample size and asymmetric loss to follow-up, the above findings should be considered exploratory and hypothesis-generating rather than definitive conclusions.
方法
(3) Patients with ≥ 70% diameter stenosis confirmed by quantitative coronary angiography (QCA), with small vessel diameters measuring 2.25–2.75 mm.；Eighteen patients refused angiographic follow-up due to lack of symptoms, financial constraints, or fear of invasive procedures, resulting in a final cohort of 210 patients.；CAG was performed within 24 h before the procedure, immediately post-procedure, and at 6 and 12 months using standardized techniques.
核心结论
These results indicate equivalent performance in lumen diameter improvement and stenosis reduction.；In conclusion, for de novo non-complex small-vessel lesions, DCB met the non-inferiority criterion compared with DES for LLL at 1-year follow-up, without significantly increasing MACE risk.
局限
Bare-metal stents (BMS) initially addressed limitations of balloon angioplasty, particularly acute closure, vascular recoil, and early restenosis [ 3 ].；Despite reducing restenosis and late lumen loss (LLL) in long-term follow-up [ 6 ], contemporary DES exhibit limitations in complex lesions such as small vessel disease (SVD).
