Cardiovascular risk factors in poly-vascular vs isolated lower extremity peripheral arterial disease. analysis from the SOLACI peripheral registry

Abstract Introduction Atherosclerotic disease in more than one vascular bed (Polyvascular disease), is a strong independent risk factor for ischemic events and has worse clinical outcomes than those with disease in a single territory. Aims The objective of the present interim analysis is to describe the differences in cardiovascular risk factors and clinical presentation between patients with isolated infra-aortic peripheral artery disease (lower limb: "LL-PAD") and patients with Polyvascular Disease ("PD": simultaneuous coexistence of LL-PAD and affection of at least one more vascular bed) from a cohort of patients undergoing LL endovascular procedures in Latinamerica. Methods Our cohort included patients from The SOLACI Peripheral Registry from March 2021 to February 2024 (a prospective, multi-center, observational, and hospital-based registry of patients with LL- PAD, treated with endovascular interventions across 10 Latin American countries, 42 centers). Patients were considered to have PD if besides LL-PAD, they had a documented history of previous myocardial infarction (MI), coronary revascularization, cerebrovascular, aortic, and/or carotid artery disease. Results A total of 1438 patients were included in the analysis. PD was present in 506 patients(35.1%), of which 225(44.5%) had previous MI; 296(58.5%) previous coronary revascularization;265(52.4%) had aortic and / or carotid disease; and 121(23.9%) had cerebrovascular disease. Patients with PD were older than those with LL-PAD(70.5±9.76 vs 68.6±10.7). PD was more prevalent in men(69.6% vs 62.4%), former smokers(48.2% vs 32.8%), hypertension(92.1% vs 80.5%) and patients with dyslipidemia(75.3% vs 64%). The distribution of treated lesions in the PD group was: 15.4% ilio-femoral; 34 % femoropopliteal; 23.3% infrapopliteal; and 24% had multiple peripheral territories affected and treated at the same time-point. In the LL-PAD group, the distribution of treated lesions was: 12.5% ilio-femoral; 28.6% femoropopliteal; 31.5% infrapopliteal; and 24.8% had multiple peripheral territories affected simultaneously and treated during the same procedure. In general, the lesions were shorter in the PD group: ilio-femoral(53.5±29.2 vs 66.7±48.2mm); femoropopliteal(119±73.6 vs 122±81.7mm); and infrapopliteal(129±83.1 vs 147±93.1mm). In the PD group, a higher percentage of patients were treated with statins and antithrombotic agents: statins (87.5% vs 70.8%), aspirin (91.5% vs 81.1%), clopidogrel (60.9% vs 40.1%), and oral anticoagulants (13.8% vs 6.5%). The use of rivaroxaban was similar in both groups (3.4% vs 3.9%). The PD group had higher intrahospital complication rates: intrahospital death (2.2% vs 0.8%), cardiovascular intrahospital death (1.2% vs 0.4%), MI (0.8% vs 0.1%), stroke (0.4% vs 0%) and bleeding (0.8% vs 0.9%). Conclusions Patients with PD represent a very high-risk population. Systematic screening of multiple vascular beds in patients with LL-PAD may be warranted to prevent worse outcomes.
