Secondary Medical Prevention among Danish Patients Hospitalised with Either Peripheral Arterial Disease or Myocardial Infarction

ObjectiveWe compared the use of secondary prevention among patients with a first-time hospitalisation for peripheral arterial disease (PAD) of the lower limb with that among patients with a first-time hospitalisation for myocardial infarction (MI).Design and materialsPopulation-based follow-up study between 1997 and 2003 using registry data from the counties of Northern Jutland, Aarhus and Viborg, Denmark.ResultsBetween 1997 and 2003, within 180 days after hospital discharge, 26% of patients with lower limb PAD (n = 3,424) used antiplatelet drugs, 10% statins, 22% ACE-inhibitors/AT-II receptor antagonists and 13% betablockers compared with 55%, 46%, 42% and 78% respectively among patients with MI (n = 11,927). Patients with PAD were substantially less likely than patients with MI to use antiplatelet drugs [adjusted relative risk (RR) = 0.39 (95% confidence interval (CI): 0.36–0.41)], statins [adjusted RR = 0.21 (95% CI: 0.19–0.23)], ACE-inhibitors/AT-II receptor antagonists [adjusted RR = 0.43 (95% CI: 0.40–0.47)] and beta-blockers [adjusted RR = 0.10 (95% CI: 0.09–0.11). Between 1997 and 2003 secondary prevention increased considerably in both patient groups, but the disparity in treatment persisted.ConclusionsEfforts to further increase secondary prevention among patients with PAD are needed urgently.
