Abstract

Aims: Women and men suffering from coronary artery disease differ in their risk profiles. We sought to investigate the impact of sex on two-year outcomes after BVS implantation in routine clinical practice. Methods and results: Sex-based analysis of clinical outcomes was carried out by pooling the individual patient data of the ISAR-ABSORB and KUM-ABSORB registries performed in four high-volume tertiary centres in Munich. Of the total of 1,032 patients, 259 (25.1%) were women. The primary composite endpoint of death, target vessel myocardial infarction (TV-MI) and target lesion revascularisation (TLR) up to two years occurred in 13.2% of women and 17.9% of men (p=0.12). Compared to men, women experienced numerically lower rates of TLR and definite or probable BVS thrombosis - 7.5% vs 12.4% (p=0.051) and 1.2% and 2.7% (p=0.20), respectively. Independent predictors of increased risk for TLR were use of smaller size BVS (HR 1.28, 95% CI: 1.02-1.62), while being a woman was a protective factor (HR 0.59, 95% CI: 0.35-1.00). Conclusions: BVS used in a routine setting tend to perform better among women compared to men, which might be partially related to the lower complexity of their coronary artery disease.
