Uptake of Best Medical Therapy: Secondary Prevention of Cardiovascular Disease in Vascular Surgical Patients in Western Australia.

Best medical therapy (BMT) for peripheral arterial disease (PAD), carotid artery stenosis (CAS) and abdominal aortic aneurysm (AAA) involving concomitant use of antiplatelets, lipid-lowering agents, and blood pressure control, improves patient survival and prevents clinical cardiovascular disease (CVD). We performed a single-center cross-sectional study, over a 4-year period, describing BMT use in Western Australian patients with symptomatic PAD, CAS and AAA in the community. Overall, 45.3% of our cohort (n = 1689) were on appropriate BMT (CAS, 58.1%; PAD, 43.1%; AAA, 41.1%). There was highest uptake of blood pressure control at 93.0% (lipid-lowering agents, 65.3%; antithrombotics 63.5%). PAD was associated with highest uptake of blood pressure control (PAD 93.9%; CAS, 91.4%; AAA, 91.1%, P = .092) whilst CAS had highest uptake of antithrombotics (CAS 76.3%; PAD, 61.0%; AAA 60.4%, P < .001) and lipid-lowering agents (CAS 78.7%; PAD, 63.1%; AAA, 60.4%, P < .001). Our study indicates suboptimal use of BMT in patients with vascular disease in the community. The risk of CVD in CAS is likely misperceived as higher than PAD and AAA.
