Abstract
ABSTRACT
Introduction: Peripheral arterial disease (PAD) treatment guidelines recommend the use of statins
and antiplatelets in all PAD patients to reduce adverse cardiovascular and limb-related outcomes. In
addition, hypertension and diabetes should be treated to reach recommended targets. The aim of this
rapid review was to evaluate the level of adherence to evidence-based medical therapy (EBMT)
recommended by PAD treatment guidelines in the real-world setting.
Methods: We searched PubMed and Embase using keywords, MeSH and Emtree terms related to the
population, exposure and outcomes from their inception to 22 September 2020. We included randomised
controlled trials, non-randomised studies, and observational studies reporting adherence to at least 1 of
these 4 drug classes: (1) statins, (2) antiplatelets, (3) antihypertensives and (4) antidiabetic drugs.
Non-English articles, abstracts, dissertations, animal studies and case reports or series were excluded.
A narrative summary of the results was performed.
Results: A total of 42 articles were included in the review. The adherence to lipid-lowering drugs/statins
ranged from 23.5 to 92.0% and antiplatelets from 27.5 to 96.3%. Only 7 and 5 studies reported use of
“any anti-hypertensive” and “any anti-diabetic” medications, respectively, and the proportion of the cohort
treated were generally close to the proportion with hypertension and/or diabetes. Adherence in studies
published in 2016–2020 ranged from 52.4–89.6% for lipid-lowering drugs and 66.2–96.3% for antiplatelets.
Conclusion: EBMT adherence in PAD patients was highly variable and a substantial proportion in
many settings were undertreated. There was also a notable lack of studies in Asian populations.
Keywords: Evidence-practice gap, medication adherence, pharmacoepidemiology

Mizzi A, Cassar K, Bowen C, Formosa C. The progression rate of peripheral arterial disease in patients with intermittent claudication: a systematic review. J Foot Ankle Res 2019; 12:40. [PMID: 31404410 PMCID: PMC6683562 DOI: 10.1186/s13047-019-0351-0] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2019] [Accepted: 07/29/2019] [Indexed: 12/17/2022] Open
Abstract
Background Intermittent claudication (IC) is the most common symptom of peripheral arterial disease and is generally treated conservatively due to limited prognostic evidence to support early revascularisation in the individual patient. This approach may lead to the possible loss of opportunity of early revascularisation in patients who are more likely to deteriorate to critical limb ischaemia. The aim of this review is to evaluate the available literature related to the progression rate of symptomatic peripheral arterial disease. Methods We conducted a systematic review of the literature in PubMed and MEDLINE, Cochrane library, Elsevier, Web of Science, CINAHL and Opengrey using relevant search terms to identify the progression rate of peripheral arterial disease in patients with claudication. Outcomes of interest were progression rate in terms of haemodynamic measurement and time to development of adverse outcomes. Two independent reviewers determined study eligibility and extracted descriptive, methodologic, and outcome data. Quality of evidence was evaluated using the Cochrane recommendations for assessing risk of bias and was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results Seven prospective cohort studies and one retrospective cohort study were identified and included in this review with the number of participants in each study ranging from 38 to 1244. Progression rate reports varied from a yearly decrease of 0.01 in ankle-brachial pressure index (ABPI) to a yearly decrease ABPI of 0.014 in 21% of participants. Quality of evidence ranged from low to moderate mostly due to limited allocation concealment at recruitment and survival selection bias. Conclusions Progression of PAD in IC patients is probably underestimated in the literature due to study design issues. Predicting which patients with claudication are likely to deteriorate to critical limb ischaemia is difficult since there is a lack of evidence related to lower limb prognosis. Further research is required to enable early identification of patients at high risk of progressing to critical ischaemia and appropriate early revascularisation to reduce lower limb morbidity.

Abstract
INTRODUCTION Practice guidelines recommend that patients with peripheral artery disease receive antiplatelets, statins, and angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs). We sought to quantify the rates of prescribing these therapies in patients with peripheral artery disease in the literature. METHODS We performed a systematic review and meta-analysis of treatment prescribing rates in observational studies containing peripheral artery disease patients published on or after the year 2000. We also assessed whether prescribing rates are increasing over time. RESULTS A total of 86 studies were available for analysis. The aggregate sample size across all studies was 332,555. The pooled estimates for utilization of antiplatelets, statins, and ACE inhibitors or ARBs were 75% (95% confidence interval [CI], 71%-79%), 56% (95% CI, 52%-60%), and 53% (95% CI, 49%-58%), respectively. Statin use was directly related to publication year (+2.0% per year, P < .001), but this was not the case for antiplatelets (P = .68) or ACE inhibitors or ARBs (P = .066). CONCLUSIONS Although some improvement in statin prescribing has occurred in recent years, major practice gaps exist in the treatment of peripheral artery disease. Effective measures to close these gaps should be implemented.

Abstract
BACKGROUND Smoking rates have declined; however, it remains the primary modifiable risk factor for vascular disease. While vascular surgeons often advise patients to quit, few provide assistance. We sought to understand patients' interest in quitting and determine factors that influence this willingness to quit. METHODS Anonymous surveys were given to vascular surgery clinic patients in a single institution over a 5-month period. Demographic information, smoking status, cessation attempts, and barriers to quitting were obtained. Nicotine dependence was determined using the Fagerstrom Test, and willingness to quit was assessed using a contemplation ladder. Patient's willingness to quit was evaluated in relation to symptomatic status, previous/planned operation, and nicotine dependence levels. RESULTS A total of 490 patients (92%) completed the survey with 109 (22%) current smokers, 195 (40%) former smokers, and 186 (38%) never smokers. Never smokers were more likely to be female and employed while smokers were more likely to be disabled. Although 51% of smokers displayed moderate/high nicotine dependence, 54% demonstrated willingness to consider quitting within 6 months. The primary barrier to cessation identified was previous failed attempt(s) to quit in 44%. Most (90%) had previously attempted quitting, 63% attempted 3 or more times, and the most common technique used was "quitting cold turkey". Fifty-nine percent of patients reported physicians' had offered assistance in cessation, but only 2% had been in a cessation program. There was no correlation between willingness to consider quitting and symptomatic status, previous/planned operation, or nicotine dependence. Smokers of less than 10 cigarettes/day had a lower nicotine dependence level (P = 0.0001) and higher willingness to consider quitting (P = 0.0015), as did those who had fewer failed prior attempts to quit and who did not believe it was too late to quit. CONCLUSIONS Most of our vascular patients self-report as nonsmokers. Over half of those who smoke demonstrate willingness to consider quitting within 6 months, which is not dependent on nicotine dependence, previous/planned operation, or symptomatic status. Those who smoke less than 10 cigarettes per day, have fewer past failed attempts to quit, and believe that it is not too late to quit are more likely to consider quitting. Vascular surgeons should be more aware of previous quit attempts and patterns of smoking and be proactive in assisting patients in cessation attempts.

Risk Factor Modification Behaviors of Practicing Vascular Surgeons. Ann Vasc Surg 2017; 46:90-96. [PMID: 28572029 DOI: 10.1016/j.avsg.2017.05.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2017] [Revised: 05/04/2017] [Accepted: 05/11/2017] [Indexed: 11/24/2022]
Abstract
BACKGROUND National smoking rates have declined; however, it remains the primary modifiable risk factor for nearly all vascular disease. While vascular surgeons have the availability to treat patients via medical or surgical/endovascular means, involvement in risk factor modification may be lacking. This study seeks to understand vascular surgeons' involvement in tobacco cessation and risk factor modification and to determine if practice variables had any effect on provision of these services to vascular surgery patients. METHODS Anonymous electronic surveys examining tobacco cessation and risk factor modification were sent to the Vascular & Endovascular Surgery Society members (n = 633). Influence of time from training, practice type (dichotomized into academic and nonacademic vascular surgeons), hospital size, region, and workload was assessed, and data were analyzed by univariate contingency tables. RESULTS A total of 149 (24%) surveys were completed. While the majority of respondents ask patient's smoking status (97%), assess willingness to quit (84%), and advise patients to quit (95%), only 34% prescribe medications to assist in cessation, 7% see patients in tobacco cessation follow-up, and 3% verify cessation with cotinine levels or carbon monoxide monitoring. Surgeons who prescribed medications for cessation are more likely to assess patient's willingness to quit, prescribe/advise nicotine replacement, or prescribe initial statin or other lipid-lowering medications. There was no difference in perceived education received during training in risk factor modification, but only 26% of respondents thought they were well trained. Comparing academic to private practice vascular surgeons, there was no difference in cessation techniques used; however, academic surgeons were less likely to perform endovascular procedures for claudication in patients who continued to smoke (29% vs. 46%, P = 0.03) and more likely to prescribe an initial antihyperlipid medication (65% vs. 39%, P = 0.0018). CONCLUSIONS Tobacco dependence remains a critical issue for vascular surgery patients; however, there is wide variation in cessation techniques used. The majority of vascular surgeons are not well versed in cessation techniques and risk factor modification, and thus, efforts should be made to provide this education in vascular surgery training programs.

Abstract
Background Prevalence of peripheral arterial disease (PAD) has dramatically increased in both developing, as well as developed countries. However, significant knowledge and practice gaps persist. In Canada, efforts to improve this knowledge level are lacking. In this study, we examine PAD knowledge in Toronto, and evaluate a pilot intervention to address the knowledge gaps. Objectives Measure PAD awareness in Toronto, and evaluate an intervention to improve PAD knowledge among the public. Methods In the context of a community-based awareness campaign, an interview-based survey was used to assess the PAD awareness among general public. A sample of participants was split into two arms: control (survey only) and intervention (survey and education pamphlet), the choice between assigning the site as case or control was random. A follow-up telephone and email-based survey was conducted after 6 weeks to assess the attained knowledge level of PAD. Results Two hundred thirty-seven participants completed the baseline survey. One hundred eighty-eight participants (78.7%) had never heard of PAD. The remaining “PAD-aware” cohort had low overall knowledge of the disease characteristics. Participants from each arm completed the follow-up survey. The level of education, age, and gender were not predictors of knowledge scores; however, age was a predictor of PAD awareness, while gender and level of education were not. Participants in the intervention group showed significant knowledge scores improvement in five PAD domains, while those from control group showed significant improvement in their preventative measures, treatment modalities, and total scores. The impact of the study intervention on average scores was borderline not significant ( p = 0.05). Conclusion PAD knowledge gap in the Canadian public is larger than what was previously reported. Educational campaigns are necessary to address this gap and improve the outcome of PAD patients through patients' activation. Our results are encouraging and warrant a next intervention to explore an educational program impact on PAD knowledge.

Impact and Duration of Brief Surgeon-Delivered Smoking Cessation Advice on Attitudes Regarding Nicotine Dependence and Tobacco Harms for Patients with Peripheral Arterial Disease. Ann Vasc Surg 2016; 38:113-121. [PMID: 27521828 DOI: 10.1016/j.avsg.2016.06.005] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2016] [Revised: 05/31/2016] [Accepted: 06/03/2016] [Indexed: 02/08/2023]
Abstract
BACKGROUND Despite the recognized benefits of smoking cessation, many clinicians question if a brief smoking cessation intervention can help dedicated smokers with peripheral arterial disease understand nicotine dependence and harms related to smoking. We investigated the impact and durability of a multimodal smoking cessation intervention on patient attitudes regarding nicotine dependence and the health effects of smoking. METHODS We conducted a pilot cluster-randomized trial of a brief smoking cessation intervention at 8 vascular surgery practices between September 1, 2014 and August 31, 2015. Compared with control sites, patients at intervention sites received protocolized brief cessation counseling, medications, and referrals to a quitline. After their clinic visit and again at 3 months, participants completed a brief survey about patient attitudes regarding nicotine dependence and the health effects of smoking. Responses to questions were analyzed using chi-squared test and Student's t-test. RESULTS All trial participants (n = 156) complete the initial survey, and 75 (45%) participants completed the follow-up survey. Intervention and control patients both reported a greater than 30-pack-year history (80% vs. 90%, P = 0.07) and previous failed quit attempts (77% vs. 78%, P = 0.8). Compared with usual care, patients in the intervention group were more likely to describe hearing advice to quit from their surgeon (98% vs. 77%, P < 0.001), and expressed "a lot" or "some" interest in quitting (95.4% vs. 85.7%, P = 0.05). Patients in the intervention group were also more likely to acknowledge their addictive behaviors, consistently scoring higher on question bank items regarding nicotine addiction (52.9 vs. 48.0, P = 0.006) and the negative health effects of smoking (scaled score 56.6 vs. 50.6, P = 0.001). When resurveyed 3 months after intervention, patients in the intervention group had larger declines in nicotine dependence and health effect domains, suggesting durable impact of the intervention on patient attitudes regarding nicotine addiction and smoking harms. CONCLUSIONS Brief smoking cessation counseling by a vascular surgeon increases patient interest in smoking cessation and awareness of smoking harms, and this effect was durable 3 months after intervention. This evidence suggests that even brief counseling within a surgical clinic has the potential to impact patient desire to quit.

Abstract
Aim To identify patients who are under higher threat for migration because of an old generation stent graft application. Methods A systematic review and meta-analysis of the literature was undertaken to identify all studies which included older generation endografts and data reporting on graft migration after EVAR. Outcome data were pooled and combined, and were calculated using fixed or random effects models. Results From 2000 to 2014, 22 retrospective studies were identified reporting on stent- graft migration after EVAR (8.6%). From those patients, 39% received re-intervention with the mean time of identification ranging from 12 to 36 months. Six of these retrospective nonrandomized studies were eligible for meta-analysis. AAA diameter (AAA diameter: 0.719 mm; 95% confidence interval [CI]: 0.00065–1.4384 mm; p = 0.00497) and neck length (neck length: 4.36 mm; 95% CI: 1.3277–7.394; p = 0.0048) were the only significant factors associated with stent- graft migration. Neck diameter and neck angulation did not have any important influence on stent-graft migration. Conclusions Patients with large AAA and short necks who were treated with older generation stent grafts such as AneurX and Talent are in higher risk for endograft migration than others. Stent- graft migration consists of an insidious and underestimated threat.

Abstract
BACKGROUND Peripheral artery disease (PAD) is a major cause of cardiovascular ischemic events and amputation. Knowledge gaps exist in defining and measuring key factors that predict these events. The objective of this study was to assess whether duration of limb ischemia would serve as a major predictor of limb and patient survival. METHODS The FReedom from Ischemic Events: New Dimensions for Survival (FRIENDS) registry enrolled consecutive patients with limb-threatening peripheral artery disease at a single tertiary care hospital. Demographic information, key clinical care time segments, functional status and use of revascularization, and pharmacotherapy data were collected at baseline, and vascular ischemic events, cardiovascular mortality, and all-cause mortality were recorded at 30 days and 1 year. RESULTS A total of 200 patients with median (interquartile range) age of 76 years (65-84 years) were enrolled in the registry. Median duration of limb ischemia was 0.75 days for acute limb ischemia (ALI) and 61 days for chronic critical limb ischemia (CLI). Duration of limb ischemia of <12, 12 to 24, and >24 hours in patients with ALI was associated with much higher rates of first amputation (P = .0002) and worse amputation-free survival (P = .037). No such associations were observed in patients with CLI. CONCLUSIONS For individuals with ischemic symptoms <14 days, prolonged limb ischemia is associated with higher 30-day and 1-year amputation, systemic ischemic event rates, and worse amputation-free survival. No such associations are evident for individuals with chronic CLI. These data imply that prompt diagnosis and revascularization might improve outcomes for patients with ALI.

Abstract
The generalized term 'peripheral vascular disease' (PVD) may be used to refer to vascular disorders in any non-coronary arterial bed. The more specific term 'peripheral arterial disease' (PAD) is used to refer to a more specific process, atherosclerotic disease of the lower extremities. PAD is common. Conservative estimates suggest more than 8 million Americans may be affected by PAD. Since atherosclerosis is a systemic process, PAD should be identified as a coronary heart disease risk equivalent. However, PAD remains an under-diagnosed and under-recognized risk for cardiovascular morbidity and mortality. PAD symptoms may range from non-specific ambulatory leg complaints, to typical symptoms of intermittent claudication to critical limb ischaemia with rest pain, gangrene or ulceration. These symptoms directly impact quality of life and may affect functional capacity. There are two therapeutic goals for patients with PAD: first, to reduce the risk of cardiovascular events and second, to manage the lower extremity symptoms. This manuscript reviews the medical management of patients with PAD, briefly discussing the goals of cardiovascular risk factor modification and then focusing on pharmacological management strategies for patients with intermittent claudication and critical limb ischaemia.

Abstract
The saphenous vein remains the most widely used conduit for peripheral and coronary revascularization despite a high rate of vein graft failure. The most common cause of vein graft failure is intimal hyperplasia. No agents have been proven to be successful for the prevention of intimal hyperplasia in human subjects. The renin-angiotensin system is essential in the regulation of vascular tone and blood pressure in physiologic conditions. However, this system mediates cardiovascular remodeling in pathophysiologic states. Angiotensin II is becoming increasingly recognized as a potential mediator of intimal hyperplasia. Drugs modulating the renin-angiotensin system include angiotensin-converting enzyme inhibitors and angiotensin receptor blockers. These drugs are powerful inhibitors of atherosclerosis and cardiovascular remodeling, and they are first-line agents for management of several medical conditions based on class I evidence that they delay progression of cardiovascular disease and improve survival. Several experimental models have demonstrated that these agents are capable of inhibiting intimal hyperplasia. However, there are no data supporting their role in prevention of intimal hyperplasia in patients with vein grafts. This review summarizes the physiology of the renin-angiotensin system, the role of angiotensin II in the pathogenesis of cardiovascular remodeling, the medical indications for these agents, and the experimental data supporting an important role of the renin-angiotensin system in the pathogenesis of intimal hyperplasia.

Abstract
Background. The aim of the study was to determine the secondary preventive medical supply of patients with peripheral arterial disease (PAD) in German primary care. Methods and Results. A population-based case control study was conducted using electronic medical records of patients extracted from the CONTENT primary care database of Heidelberg, Germany, between April 2007 and March 2010. The prescription rates of cardiovascular medication among symptomatic PAD patients were analysed by means of the ATC classification and compared with those of patients with cardiovascular disease (CVD). 479 cases with PAD and 958 sex- and age-matched control CVD patients were identified. PAD patients showed significantly lower prescription rates for cardiac agents (21.7% versus 37%), β-blockers (50.1% versus. 66.2%), and lipid-lowering agents (50.3% versus 55.9%) compared to CVD patients. In contrast, significantly more prescriptions of antidiabetic agents (28.2% versus 20.3%), particularly insulin and analogues (12.5% versus 8%), and calcium channel blockers (29.2% versus 24.3%) were found in PAD patients. Low-dose aspirin use among both PAD and CVD patients was underestimated, as it is available without a prescription. Conclusions. Optimal pharmacotherapeutical care of patients with PAD requires more intensive cardioprotective medication in primary care settings.

Abstract
Nowadays more and more clinical guidelines are developed. Clinical guidelines aim to assist practitioner and patient decision making about appropriate care for specific clinical conditions. Furthermore, guidelines can play a crucial role in the quality cycle form guidelines to clinical practice. However, this does not necessarily mean that these guidelines are actually implemented and the ultimately goal, improved patient outcome, is achieved. Care gaps exist between guidelines and daily clinical practice in perioperative care. Research should be focused on identification of barriers to adherence and subsequent effect implementation strategies to achieve higher standards of quality of care. A multifactorial approach to improving use of guidelines in clinical practice may improve the treatment of patients with peripheral arterial disease.

Abstract
PURPOSE To review the identification of patients at risk of secondary ischemic events, discuss the therapies available for their medical management, and identify the role of the nurse practitioner (NP) in their primary and long-term care. DATA SOURCES ACC/AHA 2007 guidelines for the management of patients with unstable angina and non-ST-elevation myocardial infarction, ACC/AHA 2005 guidelines for the management of patients with peripheral arterial disease, AHA/ASA 2006 guidelines for patients with ischemic stroke, AHA/ACC 2006 guidelines update for patients with coronary and other atherosclerotic vascular disease, and selected clinical articles identified through PubMed. CONCLUSIONS Preventive therapy in patients with atherothrombotic vascular disease is critical for reducing the risk of recurrent events. Almost all patients with atherosclerotic disease will benefit from general lifestyle modifications, and most will also benefit from appropriate pharmacotherapies targeting dyslipidemia, diabetes, hypertension, and platelet function. However, evidence suggests that secondary prevention strategies may not be utilized effectively. IMPLICATIONS FOR PRACTICE Increased awareness and implementation of clinical practice guidelines can reduce the risk of recurrent atherothrombotic events. NPs in primary care settings or in long-term care facilities are well placed to determine whether patients are receiving appropriate preventive care and to implement improvements in their management.

Abstract
Abstract Atherosclerotic peripheral arterial disease (PAD) is highly prevalent in the elderly and subjects with atherosclerotic risk factors such as smoking, diabetes mellitus, hypertension, and hyperlipidemia. Importantly, PAD is rarely an isolated condition, but rather a manifestation of systemic atherosclerosis. Hence, there is often coexisting disease in the coronary and cerebral arteries and, consequently, an increased risk of myocardial infarction and stroke. Intermittent claudication is the classic symptom of PAD, yet up to 50% of patients are asymptomatic. Despite the availability of reliable, non-invasive screening tests, PAD is largely underdiagnosed and undertreated, mostly due to the paucity of symptoms and underutilization of screening tools. The ankle-brachial index (ABI), a simple, rapid, and inexpensive diagnostic tool, holds much prognostic value for PAD diagnosis and is ideal for implementation in the primary care physician's office. The early detection of PAD with ABI screening and subsequent medical management represents a critical opportunity to prevent considerable vascular morbidity and mortality. The management of PAD must address claudication symptoms (with cilostazol or pentoxifylline, or in severe cases endovascular or surgical revascularization) and modifiable atherosclerotic risk factors (with an aggressive global risk-reduction regimen involving lifestyle modifications, exercise, smoking cessation, and antiplatelet, lipid-lowering, and antihypertensive therapy).

Abstract
Atherosclerosis is a systematic disease presenting with a significant overlapping of cardiovascular disorders implicating coronary heart disease and its equivalents, peripheral arterial disease, carotid arterial disease, and aneurysm disease. Evaluating patient's atherosclerotic risk profile is essential to guide primary and secondary prevention. Atherosclerotic risk factor modifications reduce, significantly, cardiovascular disease mortality and morbidity, particularly in high-risk patients. This article provides a reference guide for all conventional (eg, smoking, dyslipidemia, hypertension) and evolving (eg, homocysteine, C-reactive protein, fibrinogen, inflammatory markers) risk factors of atherosclerosis and recommends the currently effective strategies for an overall cardiovascular risk reduction. As vascular surgeons, by definition, conduct the overall management of patients with vascular disease understanding of the development, assessment, and management of atherosclerotic risk factors should remain among their highest priorities.

Abstract
Background: Risk factor modification is important in patients with vascular disease. Guidelines suggest that this patient population benefits from a medical regimen of antiplatelets, statins, β-blockers, and angiotensin-converting enzyme (ACE) inhibitors. Materials and Methods: The medical regimen of consecutive patients who presented for major vascular surgery intervention over 18 months was examined. Results: Of the 325 patients identified, 176 (54%) were on antiplatelet treatment, 197 (61%) were on a statin, 180 (55%) on β-blockers, and 146 (54%) on ACE inhibitors. A high-risk subset of 94 smokers with known coronary artery disease, hypertension, and hyperlipidemia or diabetes was identified. In this subset, patients were more likely to be on pharmacologic risk factor modification. Conclusions: Despite recommendations, the pharmacologic risk factor modification of patients prior to vascular surgery remains suboptimal. Increased awareness of the problem and active participation of the vascular specialist are essential to improve compliance with established guidelines.

Abstract
BACKGROUND Peripheral arterial disease (PAD) is a common manifestation of systemic atherosclerosis associated with a high risk of morbidity and mortality from cardiovascular events. Despite this, PAD is often undiagnosed and, therefore, undertreated. OBJECTIVE The purpose of this review is to highlight and provide clinical insight into the similarities and differences between the available PAD treatment guidelines developed by the American College of Cardiology/American Heart Association (ACC/AHA) and the Trans-Atlantic Inter-Society Consensus II (TASC II) working group. METHODS Recommendations from the ACC/AHA 2005 Practice Guidelines for the Management of Patients with Peripheral Arterial Disease (Lower Extremity, Renal, Mesenteric, and Abdominal Aortic) and TASC II Inter-Society Consensus for the Management of Peripheral Arterial users for personal Disease, initiated in 2004 and published in 2007, were compared. Supplemental information was obtained by searching the PubMed and MEDLINE databases using relevant terms. Unintentional bias may have been introduced into the manuscript by not performing a systematic review of the literature with pre-defined search terms. FINDINGS AND CONCLUSIONS While some variation exists in the content of the recommendations, both documents agree on the need for aggressive management of patients with PAD. In spite of these recommendations, there is a general lack of adherence to the current guidelines-a critical concern considering the high morbidity and mortality associated with the disease. However, the results of ongoing clinical trials may serve to increase awareness of the importance of aggressive management of PAD.

Abstract
Established vascular risk factors (ie, smoking, hypertension, diabetes mellitus, and dyslipidemia) play an important role in the development of vascular disease. Emerging evidence suggests that some of these risk factors may have a more intense effect on specific arterial beds, a finding that holds implications for a prognostic role for certain types of vascular disease.
