Abstract
Comprehensively managing vascular disease in the United States can seem overwhelming. Vascular surgery providers encounter daily stress-inducing challenges, including caring for sick patients who often, because of healthcare barriers, struggle with access to care, socioeconomic challenges, and a complex medical system. These individuals can present with advanced disease and comorbidities, and many have limited treatment options. Subsequently, it could seem as if the vascular surgeon's efforts have little opportunity to make a difference. This review describes a method to counter this sentiment through directed action, hope, and community building. Vascular surgeons are passionate about what they do and are built to fight healthcare disparities. This review also outlines the reasoning for attempting to create change and one approach to begin making a difference.

BMJ Open 2023; 13:e076399. [PMID: 37989360 PMCID: PMC10668189 DOI: 10.1136/bmjopen-2023-076399] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Accepted: 11/03/2023] [Indexed: 11/23/2023] Open
Abstract
OBJECTIVES We aimed to investigate the regional variations in the number of interventions and surgeries for peripheral artery disease (PAD) and explore the major determinants of the variations. DESIGN Cross-sectional study. SETTING The Japanese Ministry of Health, Labour and Welfare National Database and Diagnostic Procedure Combination database in 2018. DATA The rates of endovascular treatment (EVT), bypass surgery per 100 000 individuals in the population were calculated for all 47 prefectures in Japan. The total annual changes in the rates of EVT and bypass surgery in Japan from 2012 to 2019 were calculated. ANALYSIS A linear regression model was developed with rates of EVT and bypass surgery as dependent variables and regional medical supply in each prefecture as explanatory variables. These regional factors included the rate of percutaneous coronary intervention (PCI) for angina, the numbers of cardiovascular specialists, specialists in cardiac surgery, interventional radiology (IVR) training facilities and cardiovascular surgery training facilities, per 100 000, respectively. RESULTS There was a 5.7-fold difference (143 and 25 per 100 000 individuals aged ≥40 years) in the highest and lowest EVT rates. The highest and lowest rates of bypass surgery were 34 and <10 per 100 000 individuals aged ≥40 years in a prefecture, respectively. The rate of PCI contributed most significantly positive to the rate of EVT (p<0.001). However, the numbers of IVR and cardiovascular surgery training facilities had significant positive and negative relationships, respectively, with the rate of EVT. The numbers of specialists in cardiac surgery and cardiovascular specialists had significant positive (p=0.01) and negative (p=0.01) correlations, respectively, with the rate of bypass surgery. CONCLUSIONS Considerable regional variations in the rates of revascularisation for PAD were found. Unbalanced presence of medical resources, preference of suppliers and the training system had larger effects on the regional variation in Japan.

Abstract
PURPOSE This narrative review summarizes recent research examining treatment targets for peripheral artery disease (PAD)-related limb ischemia. METHODS Targeted searches of the PubMed and clinical trial registry databases were performed to identify recent findings from animal models of limb ischemia and clinical studies examining PAD progression and treatment. Ongoing clinical trials testing new treatments for PAD were also reviewed. Relevant full-text articles were retrieved and critically reviewed. Where indicated, data were tabulated and summarized in the text. FINDINGS Most people with PAD need treatment to improve their walking and function and limit leg pain. Currently, the available treatments of cilostazol, exercise therapy, and revascularization have several deficiencies, including limited access, poor uptake, limited efficacy, and risk of complications. Severe PAD threatens limb viability and is treated by endovascular or open surgical revascularization but is not always successful in achieving limb salvage. Research is ongoing to develop and test new therapies, including new exercise programs, drugs, stem cell treatments and RNA therapeutics, so that new and adjunctive PAD treatments can be offered. Results from multiple clinical trials are expected within the next 5 years. IMPLICATIONS It is envisaged that a range of new therapies for PAD will be available in the future.

Luong B, Brown CM, Humphries MD, Maximus S, Kwong M. Assessing the Utility of Toe Arm Index and Toe Pressure in Predicting Wound Healing in Patients Undergoing Vascular Intervention. Ann Vasc Surg 2023; 97:221-235. [PMID: 37659650 DOI: 10.1016/j.avsg.2023.08.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 08/06/2023] [Accepted: 08/15/2023] [Indexed: 09/04/2023]
Abstract
BACKGROUND Objective measures of perfusion such as an ankle-brachial index (ABI) and toe pressure remain important in prognosticating wound healing. However, the use of ABI is limited in patients with incompressible vessels and toe pressure may not be comparable across patients. While a toe arm index (TAI) may be of value in this setting, its role as clinical indicator of perfusion for healing in patients with lower-extremity wounds has not been well established. METHODS A retrospective review was performed of all vascular patients with lower-extremity wounds that underwent peripheral vascular intervention between 2014-2019. Data regarding patient demographics, comorbidities, TAI, ABI, toe pressures, and the wound, ischemia, and foot infection (WIfI) score were collected. Associations between patient variables and wound healing at various time points were evaluated. RESULTS A total of 173 patients (67.7 ± 10.9 years; 71.1% male) were identified with lower-extremity wounds. Most patients underwent endovascular intervention (77.5%). Patients were followed for a median of 416 (IQR 129-900) days. Mean postoperative TAI was 0.35 ± 0.19 and mean WIfI score was 2.60 ± 1.17. Nine percent (15) of patients healed within 1 month, 44.8% (69) healed within 6 months, and 65.5% (97) healed within 1 year of revascularization without need for major amputation. Those that healed within 1 year without any major amputation did not differ from those that did not heal based on age, gender, race, comorbidities, periprocedural medications, or procedures performed. However, patients that healed without major amputation had a higher postoperative TAI (0.38 vs. 0.30, P = 0.02), higher toe pressure (53 vs. 40 mm Hg, P = 0.004), and lower WIfI score (2.26 vs. 3.12, P < 0.001). Patients that healed with 1 year without requiring any amputation had similar associations with postoperative TAI, toe pressure, and WIfI. Additionally, they were more likely to be White (P = 0.019) and have an open surgical procedure (P < 0.001) and less likely to have chronic kidney disease (P = 0.001) or diabetes (P = 0.008). A Youden index was calculated and identified a TAI value of 0.30 that optimized sensitivity and specificity for wound healing. The area under the curve for TAI as a predictor of wound healing was 0.62. CONCLUSIONS Higher postoperative TAI is associated with higher odds of wound healing without need for major amputation. Toe arm index is therefore a useful tool to identify patients with adequate arterial perfusion to heal lower-extremity wounds. However, the area under the curve is poor for TAI when used as a sole predictor of wound healing potential suggesting that TAI should be one of multiple factors to considered when prognosticating wound healing potential.

Abstract
BACKGROUND The prevalence of peripheral artery disease (PAD) and leg symptoms are higher in Black than White adults. We studied the effects of self-reported lower extremity symptoms and ankle-brachial indices (ABI) groups on outcomes. METHODS Black participants in the Jackson Heart Study with baseline ABI and PAD symptom assessments (exertional leg pain by the San Diego Claudication questionnaire) were included. Abnormal ABI was < 0.90 or > 1.40. Participants were divided into (1) normal ABI, asymptomatic, (2) normal ABI, symptomatic, (3) abnormal ABI, asymptomatic, and (4) abnormal ABI, symptomatic to examine their associations with MACE (stroke, myocardial infarction, fatal coronary heart disease) and all-cause mortality, using Kaplan-Meier survival curves and stepwise Cox proportional hazard models adjusting for Framingham risk factors. RESULTS Of 4586 participants, mean age was 54.6 ± 12.6 years, with 63% women. Compared with participants with normal ABI who were asymptomatic, participants with abnormal ABI and leg symptoms had highest risk of MACE (adjusted HR 2.28; 95% CI 1.62, 3.22) and mortality (aHR 1.82; 95% CI 1.32, 2.56). Participants with abnormal ABI without leg symptoms had higher risk for MACE (aHR 1.49; 95% CI 1.06, 2.11) and mortality (aHR 1.44; 95% CI 1.12, 1.99). Participants with normal ABI and no leg symptoms did not have higher risks. CONCLUSION Among Black adults, the highest risk for adverse outcomes were in symptomatic participants with abnormal ABIs, followed by asymptomatic participants with abnormal ABIs. These findings underscore the need for further studies to screen for PAD and develop preventative approaches in Black adults with asymptomatic disease.

Abstract
Peripheral artery disease (PAD) is a debilitating disease that disproportionately affects people of low socioeconomic status and racial minority individuals. These groups also tend to have lower rates of revascularization and worse outcomes, including higher rates of major amputation. In 2010, the Affordable Care Act (ACA) was signed into law, providing better opportunities for health care access to millions of uninsured Americans, although the implementation of different components started at a later date. Political issues led to uneven adaptation by states of the different ACA components. In states that adopted Medicaid expansion under the ACA, similar to that under the Massachusetts Health Care Reform Law of 2006, patients of low socioeconomic status and racial minority patients gained better access to health care. This review article will examine the disparities that exist in peripheral artery disease outcomes, as well as the effects of the ACA and Medicaid expansion on revascularization, limb salvage, and major amputation rates.

A brief review on the impact of dual-eligible status on health disparities and peripheral artery disease. Semin Vasc Surg 2023; 36:64-68.

Abstract
Peripheral artery disease (PAD) has been associated with poorer outcomes based on particular social determinants of health, including insurance status. A unique population to study treatment outcomes related to PAD is those with dual-eligible status-those who qualify for both Medicare and Medicaid-comprising more than 12 million people. We performed a systematic review of the literature surrounding dual-eligible patients and impact on PAD, with final inclusion of six articles. Dual eligibility has been associated with higher rates of comorbidities; more severe symptoms at initial presentation for PAD; and poorer treatment outcomes, including mortality. Further studies are needed to specifically look at the association between PAD and dual-eligible status, but what is clear is that patients in this population would benefit from early identification to prevent disease progression and improve equity.

Abstract
BACKGROUND Peripheral artery disease (PAD) is associated with modifiable atherosclerotic risk factors like hypertension, diabetes, hyperlipidemia, and smoking. However, the effect of risk factor control on outcomes and disparities in achieving control is less well understood. METHODS All patients in an integrated, regional health system with PAD-related encounters, fee-for-service Medicare, and clinical risk factor control data were identified. Component risk factors were dichotomized into controlled and uncontrolled categories (control defined as low-density lipoprotein < 100 mg/dL, hemoglobin A1c < 7.0%, SBP < 140 mmHg, and current nonsmoker) and composite categories (none, 1, ⩾ 2 uncontrolled RFs) created. The primary outcome was major adverse vascular events (MAVE, a composite of all-cause mortality, myocardial infarction, stroke, and lower-extremity revascularization and amputation). RESULTS The cohort included 781 patients with PAD, average age 72.5 ± 9.8 years, of whom 30.1% were Black, and 19.1% were Medicaid dual-enrolled. In this cohort, 260 (33.3%) had no uncontrolled risk factors and 200 (25.6%) had two or more uncontrolled risk factors. Patients with the poorest risk factor control were more likely to be Black (p < 0.001), Medicaid dual-enrolled (p < 0.001), and have chronic limb-threatening ischemia (p = 0.009). Significant differences in MAVE by degree of risk factor control were observed at 30 days (none uncontrolled: 5.8%, 1 uncontrolled: 11.5%, ⩾ 2 uncontrolled: 13.6%; p = 0.01) but not at 1 year (p = 0.08). risk factor control was not associated with outcomes at 1 year after adjustment for patient and PAD-specific characteristics. CONCLUSIONS risk factor control is poor among patients with PAD. Significant disparities in achieving optimal risk factor control represent a potential target for reducing inequities in outcomes.

Abstract
Peripheral artery disease (PAD), the pathophysiologic narrowing of arterial blood vessels of the lower leg due to atherosclerosis, is a highly prevalent disease that affects more than 6 million individuals 40 years and older in the United States, with sharp increases in prevalence with age. Morbidity and mortality rates in patients with PAD range from 30% to 70% during the 5- to 15-year period after diagnosis and PAD is associated with poor health outcomes and reduced functionality and quality of life. Despite advances in medical, endovascular, and open surgical techniques, there is striking variation in care among population subgroups defined by sex, race and ethnicity, and socioeconomic status, with concomitant differences in preoperative medication optimization, amputation risk, and overall health outcomes. We reviewed studies from 1995 to 2021 to provide a comprehensive analysis of the current impact of disparities on the treatment and management of PAD and offer action items that require strategic partnership with primary care providers, researchers, patients, and their communities. With new technologies and collaborative approaches, optimal management across all population subgroups is possible.

Abstract
Approximately 6% of adults worldwide have atherosclerosis and thrombosis of the lower limb arteries (peripheral artery disease (PAD)) and the prevalence is rising. PAD causes leg pain, impaired health-related quality of life, immobility, tissue loss and a high risk of major adverse events, including myocardial infarction, stroke, revascularization, amputation and death. In this Review, I describe the pathophysiology, presentation, outcome, preclinical research and medical management of PAD. Established treatments for PAD include antithrombotic drugs, such as aspirin and clopidogrel, and medications to treat dyslipidaemia, hypertension and diabetes mellitus. Randomized controlled trials have demonstrated that these treatments reduce the risk of major adverse events. The drug cilostazol, exercise therapy and revascularization are the current treatment options for the limb symptoms of PAD, but each has limitations. Novel therapies to promote collateral and new capillary growth and treat PAD-related myopathy are under investigation. Methods to improve the implementation of evidence-based medical management, novel drug therapies and rehabilitation programmes for PAD-related pain, functional impairment and ischaemic foot disease are important areas for future research.

Abstract
AIM Healthcare disparities can affect access and quality of care among many in the United States (US). In addition to race, we sought to assess if geography affected rates of cardiac arrest, and the subsequent outcomes. METHODS Using the National Inpatient Sample database from 2006-2018, we assessed rates of cardiac arrest (out of hospital that survived to admission and in-hospital) and cardiac catheterization, and length of stay (LOS) in four regions: Northeast (NE), South (SO) West (W) and Midwest (MW). RESULTS Cardiac arrest increased from 27,611 (2006) to 43,333 (2018). The proportion of African American (AA) patients experiencing cardiac arrest significantly increased from 11.9% to 18.8%. The mortality decreased from 65.4% to 60.8% in all patients and 70.2% to 61.4% in AA. Mortality in AA remained higher than non-AA (OR, 1.09 [1.08-1.11], p < 0.001). When regions were compared for mortality, MW had a lower risk than NE 0.94[0.92-9.96]; SO 1.05[1.04-1.07] and W 1.11[1.09-1.13] were higher compared to NE. LOS decreased slightly from 9.0 days to 8.7 in all patients. LOS for AA was longer than non-AA (11.3 vs 8.6 days) with the NE having the longest LOS. AA were less likely to receive cardiac catheterization than non-AA (9.5% vs 15%) with the largest racial gap in the MW region. CONCLUSION The proportion of AA with cardiac arrests increased over the study period. Mortality and LOS improved significantly in AA from 2006 to 2018 but remain significantly higher than non-AA patients. Future research should identify contributors to these concerning trends.
