Prescriber Implementation of Guideline-Directed Medical Therapy Remains Poor in the Peripheral Artery Disease Population

Abstract Body (Do not enter title and authors here): Background
Peripheral Artery Disease (PAD) is one of the most prevalent forms of cardiovascular disease, with many progressing to CV morbidity/death. Adherence to guideline-directed optimal medical therapy (OMT) in PAD is vital. This study evaluated adherence to prescribing OMT in patients with PAD.
Methods
A retrospective study of 3,471 patients with PAD between 2017 and 2022 undergoing vascular laboratory imaging was performed. OMT was defined by 2016 AHA guidelines. Adherence to guidelines was denoted by active prescriptions for antiplatelet and statin therapy. Presence of high-intensity OMT (HIOMT) was defined as prescriptions for an antiplatelet and high-intensity statin. Prevalence and incidence (change to OMT /HIOMT within 60 days of index vascular laboratory visit) of OMT were evaluated. Multivariable models were created evaluating predictors of OMT and HIOMT prevalence and incidence.
Results
OMT prevalence was 45.3% while HIOMT prevalence was 23.6% at the time of index vascular laboratory. Incident OMT was 24.3% while incident HIOMT was 11.2% within 60 days. Age, min/max ABI, insurance status, smoking status, and comorbidities were associated with prevalent OMT/HIOMT (table 1). Age, gender, min/max ABI, smoking status, and HgbA1c were associated with incident HIOMT (table 2). In multivariable models, incident HIOMT was less likely in women (OR 0.7; 0.52-0.91) whereas lower ABIs were predictive of HIOMT (OR 0.6; 0.51-0.72).
Conclusions
Despite clear guidelines regarding OMT in patients with atherosclerotic cardiovascular disease, in this real-world study of guideline directed prescription management of PAD, adherence to OMT remains low, especially for HIOMT. Predictors of incident HIOMT include lower ABI while females were less likely to be on HIOMT. Given the high prevalence of PAD, heterogeneity of caregivers, widespread availability of screening, this population should be targeted for better adherence to HIOMT to prevent CV morbidity and death.
