In patients without a history of any ATD, incidence rates declined significantly in all groups, although the reduction in incident CHD in women was marginal (−0.7%/year, 95% CI −1.5 to +0.1%). The largest annual reductions in incidence rates were for PAD (men, −6.4%/year, 95% CI −7.7 to −5.0%; women, −5.4%/year, 95% CI −7.2 to −3.6%) and CeVD in women (−4.0%/year, 95% CI −5.0 to −3.0%). Falls in overall recurrence rates were greatest for CeVD (men, −3.2%/year, 95% CI −4.7 to −1.6%; women −4.6%/year, 95% CI −6.4 to −2.7%). Trends across all categories of polyvascular ATD were generally downward, although not all changes were statistically significant.Conclusion The incidence and recurrence rates of hospitalised ATD have decreased over time, including in patients with disease involving multiple vascular territories. This implies that primary and secondary prevention strategies have been broadly effective. However, high absolute rates of recurrence and limited reduction in 35–54-year-old individuals highlight patient groups to target to reduce further the burden of ATD. ER -
