BACKGROUND: The VOYAGER PAD trial investigated data on dual pathway inhibition after lower limb revascularisation for peripheral arterial disease (PAD). Multiple exclusion criteria were applied. However, neither data on the prevalence of exclusion criteria nor on the total number of patients screened for inclusion was discussed.
METHODS: We performed a single-center prospective observational study in unselected PAD patients undergoing lower limb revascularisation. Demographic and disease-specific data was collected.
RESULTS: 150 patients were included with only 29 patients (19.3%) as potential candidates for the VOYAGER PAD study medication. Poorly controlled diabetes or severe uncontrolled hypertension (33.3%), major tissue loss (18.7%), acute limb ischaemia within prior 2 weeks (17.3%) and a history of intracranial haemorrhage, stroke or TIA (16%) were amongst the exclusion criteria most frequently met. Compared to VOYAGER PAD study patients, significant differences regarding sex (36.7% female vs. 25.8%), renal insufficiency (29.0% vs. 20.1%), previous myocardial infarction (16.7% vs. 11.1%) and known carotid artery disease (18.7% vs. 8.6%) revealed. Patients presented significantly more frequently with critical limb ischemia (56.7% vs. 30.4%) and a history of previous peripheral revascularisation (72.0% vs. 35.9%). Fewer endovascular interventions (52% vs. 65.5%) and more surgeries (58% vs. 34.5%) were performed.
CONCLUSIONS: In unselected patients undergoing revascularisation for peripheral arterial disease, the majority presents with characteristics that, at present, preclude prescription of rivaroxaban in addition to aspirin. This patient cohort represents a population with higher rates of comorbidities and more complex vascular interventions, but might also benefit from dual pathway inhibition strategy.
