OBJECTIVES: The aim of this study was to examine whether stent length per patient and stent length per lesion are negative markers for 3-year outcomes in women following percutaneous coronary intervention (PCI) with new-generation drug-eluting stents (DES).
BACKGROUND: In the era of advanced stent technologies, whether stent length remains a correlate of adverse outcomes is unclear.
METHODS: Women treated with new-generation DES in 14 randomized trials from the WIN-DES (Women in Innovation and Drug-Eluting Stents) pooled database were evaluated. Total stent length per patient, which was available in 5,403 women (quartile 1, 8 to 18 mm; quartile 2, 18 to 24 mm; quartile 3, 24 to 36 mm; quartile 4, ≥36 mm), and stent length per lesion, which was available in 5,232 women (quartile 1, 8 to 18 mm; quartile 2, 18 to 20 mm; quartile 3, 20 to 27 mm; quartile 4, ≥27 mm) were analyzed in quartiles. The primary endpoint was 3-year major adverse cardiovascular events (MACE), defined as a composite of all-cause death, myocardial infarction, or target lesion revascularization.
RESULTS: In the per-patient analysis, a stepwise increase was observed with increasing stent length in the adjusted risk for 3-year MACE (p for trend
CONCLUSIONS: In this pooled analysis of women undergoing PCI with new-generation DES, increasing stent length per patient and per lesion were independent predictors of 3-year MACE but were not associated with definite or probable stent thrombosis.
