Abstract:

BACKGROUND: Optimal medical therapy (OMT) is a modifiable factor that decreases mortality and cardiovascular events in patients with severe peripheral arterial disease. We hypothesized that preintervention OMT would be associated with improved 1-year reintervention and major adverse limb event (MALE) rates after elective endovascular revascularization for intermittent claudication (IC). METHODS: Using the Vascular Quality Initiative (2010-2020), we identified patients with IC undergoing elective endovascular, hybrid, and open surgical interventions. Preoperative antiplatelet, statin, and nonsmoking status defined OMT components and created three groups: complete (all components), partial (1-2 components), and no OMT. The primary outcome was 1-year reintervention. Secondary outcomes included MALE and factors associated with OMT usage. Multivariable logistic regression generated adjusted odds ratios (aOR). RESULTS: There were 39,088 patients (14,907 [38.1%] complete, 22,054 [56.4%)] partial, 2127 [5.4%] no OMT) who met our criteria. Patients with any OMT were more frequently older with more cardiovascular diseases and diabetes (P  < .0001). Patients without OMT were more likely to be Black or with Medicare or Medicaid (P  < .05). Observed 1-year reintervention (5.3% complete OMT, 6.1% partial OMT, 8.3% no OMT; P  < .001) and MALE (5.6% complete OMT, 6.3% partial OMT, 8.8% no OMT; P  < .001) were decreased by partial or complete OMT compared with no OMT. Complete OMT significantly decreased the adjusted odds of reintervention and MALE by 28% (aOR, 0.72, 95% confidence interval [95% CI], 0.59-0.88) and 30% (aOR, 0.70; 95% CI, 0.58-0.85), respectively, compared with no OMT. Partial OMT decrease the adjusted odds of reintervention and MALE by 24% (aOR, 0.76; 95% CI, 0.63-0.92) and 26% (aOR, 0.74; 95% CI, 0.62-0.89), respectively. CONCLUSIONS: Preintervention OMT is an underused, modifiable risk factor associated with improved 1-year reintervention and MALE. Vascular surgeons are uniquely positioned to initiate and maintain OMT in patients with IC before revascularization to optimize patient outcomes.
