PAD Patients Less Likely to Receive Statins, Despite Increased Cardiac Event Risk: Study

To conduct this retrospective cross-sectional study, researchers reviewed data from patients with a confirmed PAD diagnosis based on invasive or noninvasive imaging. Demographic, clinical, laboratory, and treatment information was summarized using descriptive statistics. Multiple logistic regression analysis was performed to identify predictors for prescribing high-intensity statins. According to American College of Cardiology and American Heart Association guidelines, high-intensity statin therapy was defined as atorvastatin ≥40 mg per day, rosuvastatin ≥20 mg per day, or simvastatin ≥80 mg per day.

The key findings of the research were as follows:

• Statins were used by 82% of patients; however, only 39% were on high-intensity statins.
• Patients with cerebrovascular disease (CVD) had lower odds of receiving lower extremity revascularization (LIS) therapy, with an odds ratio of 0.19).
• Those on oral anticoagulants (OAC) also had lower odds of receiving LIS therapy (OR = 0.16).
• Patients on dual antiplatelet therapy (DAPT) were less likely to receive LIS therapy (OR = 0.20).

The researchers concluded that patients with PAD are less likely to receive appropriate statin therapy, despite having a high risk of future adverse cardiac events. Involvement of more vascular beds was associated with higher chances of initiating high-intensity statin.
