Lower extremity peripheral artery disease (PAD) affects >230 million adults worldwide and is associated with increased risk of various adverse clinical outcomes (other cardiovascular diseases such as coronary heart disease and stroke and leg outcomes such as amputation). Despite its prevalence and clinical importance, PAD has been historically underappreciated by health care professionals and patients. This underappreciation seems multifactorial (eg, limited availability of the first-line diagnostic test, the ankle-brachial index, in clinics; incorrect perceptions that a leg vascular disease is not fatal and that the diagnosis of PAD would not necessarily change clinical practice). In the past several years, a body of evidence has indicated that these perceptions are incorrect. Several studies have consistently demonstrated that many patients with PAD are not receiving evidence-based therapies. Thus, this scientific statement provides an update for health care professionals regarding contemporary epidemiology (eg, prevalence, temporal trends, risk factors, and complications) of PAD, the present status of diagnosis (physiological tests and imaging modalities), and the major gaps in the management of PAD (eg, medications, exercise therapy, and revascularization). The statement also lists key gaps in research, clinical practice, and implementation related to PAD. Orchestrated efforts among different parties (eg, health care providers, researchers, expert organizations, and health care organizations) will be needed to increase the awareness and understanding of PAD and improve the diagnostic approaches, management, and prognosis of PAD.

Objectives Triglyceride-glucose index (TyG index), which is defined as the simple and novel marker of insulin resistance, is becoming increasingly important as a promising predictive marker for atherosclerotic diseases. Chronic limb-threatening ischemia is defined as the most advanced stage of the lower extremity peripheral artery disease, whose main cause is atherosclerosis and is associated in this respect with amputation, impaired quality of life, and mortality. The main purpose of the present study was to investigate the relation between the calculated TyG index values and chronic limb-threatening ischemia development. Methods A total of 296 patients who were diagnosed with lower extremity peripheral artery disease in our outpatient clinic between October 2018 and October 2020 were included in this study retrospectively. Two groups were formed by clinically staging the patients according to Rutherford Classification. Patients who did not develop chronic limb-threatening ischemia were classified as “Group 1” ( n = 224) and those who developed were classified as “Group 2” ( n = 72). Results The mean TyG index values that were calculated in Group 2 were significantly higher than in Group 1 (9.27 ± 0.31 vs. 9.00 ± 0.34, p < 0.001). In the multivariate logistic regression analysis conducted to determine the predictors of chronic limb-threatening ischemia development, C-reactive protein (OR [Odds Ratio]: 1.220, 95% CI [confidence interval]: 1.092–1.363, p < 0.001), high-density lipoprotein cholesterol (OR: 0.775, 95% CI: 0.715–0.839, p < 0.001) and TyG index (OR: 5.796, 95% CI: 2.050–16.382, p = 0.001) were identified as independent predictors. Receiver operating characteristic analysis revealed that the cut-off value of TyG index was 9.13 (area under the curve: 0.721, p < 0.001) with 70.8% sensitivity and 65.2% specificity. The TyG index was significantly correlated with Rutherford category, high-density lipoprotein cholesterol and mean platelet volume. Conclusions Chronic limb-threatening ischemia development may be predicted with the TyG index value, which is calculated easily from routine biochemical parameters, in patients diagnosed with lower extremity peripheral artery disease.

Background Because of the demographic change, lower extremity peripheral artery disease (PAD) is becoming increasingly relevant with respect to health economics. PAD patients often suffer from multiple diseases. Consequently, therapy is commonly complex and requires an interdisciplinary approach. Because of rapid technical developments, interventional endovascular therapy regimens play an increasingly important role. Method Review and literature search on the basis of the current German S3 guidelines on the therapy of PAD as well as international guidelines. In terms of state-of-the-art therapies, relevant current studies were considered. Results Knowledge of existing guidelines and recommendations as well as new therapeutic approaches is essential for the adequate therapy of PAD patients. A close cooperation between the interventional radiologist and the vascular surgeon is the key to success. In addition to established conservative approaches and invasive bypass surgery, the endovascular approach has been a mainstay in the TASC A and B environment for years. It has recently shown promising results in advanced PAD conditions, such as TASC C and D. An endovascular-first strategy is defined in most guidelines. Conclusion A primarily endovascular-first strategy has become the standard in the majority of even complex lesions of the lower extremity arterial system. Regarding the crural segment, a decrease in mortality compared to bypass surgery has been demonstrated. Further evidence can be expected from ongoing randomized multicenter trials.
