Toward Uniform Case Identification Criteria in Observational Studies on Peripheral Arterial Disease: A Scoping Review. Ann Vasc Surg 2024; 106:71-79. [PMID: 38615752 DOI: 10.1016/j.avsg.2024.02.008] [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: 12/01/2023] [Revised: 02/16/2024] [Accepted: 02/16/2024] [Indexed: 04/16/2024]
Abstract
BACKGROUND The diagnosis of peripheral arterial disease (PAD) is commonly applied for symptoms related to atherosclerotic obstructions in the lower extremity, though its clinical manifestations range from an abnormal ankle-brachial index to critical limb ischemia. Subsequently, management and prognosis of PAD vary widely with the disease stage. A critical aspect is how this variation is addressed in administrative database-based studies that rely on diagnosis codes for case identification. The objective of this scoping review is to inventory the identification strategies used in studies on PAD that rely on administrative databases, to map the pros and cons of the International Classification of Diseases (ICD) codes applied, and to propose a first outline for a consensus framework for case identification in administrative databases. METHODS Registry-based reports published between 2010 and 2021 were identified through a systematic PubMed search. Studies were subcategorized on the basis of the expressed study focus: claudication, critical limb ischemia, or general peripheral arterial disease, and the ICD code(s) applied for case identification mapped. RESULTS Ninety studies were identified, of which 36 (40%) did not specify the grade of PAD studied. Forty-nine (54%) articles specified PAD grade studied. Five (6%) articles specified different PAD subgroups in methods and baseline demographics, but not in further analyses. Mapping of the ICD codes applied for case identification for studies that specified the PAD grade studied indicated a remarkable heterogeneity, overlap, and inconsistency. CONCLUSIONS A large proportion of registry-based studies on PAD fail to define the study focus. In addition, inconsistent strategies are used for PAD case identification in studies that report a focus. These findings challenge study validity and interfere with inter-study comparison. This scoping review provides a first initiative for a consensus framework for standardized case selection in administrative studies on PAD. It is anticipated that more uniform coding will improve study validity and facilitate inter-study comparisons.

Prognostic impact of disease-related complications in asymptomatic mitral regurgitation: a health insurance claims analysis. Clin Res Cardiol 2024:10.1007/s00392-024-02532-0. [PMID: 39196345 DOI: 10.1007/s00392-024-02532-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2024] [Accepted: 08/20/2024] [Indexed: 08/29/2024]
Abstract
BACKGROUND AND AIMS The impact of mitral regurgitation (MR) in asymptomatic patients is not well defined. We aimed to determine the prevalence of MR-related complications and their association with 10-year survival in a large unselected asymptomatic MR cohort. METHODS Health insurance claims data from Germany's second largest health insurance fund, BARMER, which maintains longitudinal data on 8.7 million German residents, were retrospectively analyzed. All patients with an outpatient diagnosis of MR in a minimum of two quarters during a calendar year and first recorded diagnosis between 2008 and 2011 were included. Patients with any complication attributable to MR or mitral valve intervention at index were excluded. Outcomes were compared between study group and age- and sex-matched controls (i.e., without known cardiac disease). MR-related complications of interest were new congestive heart failure, new-onset atrial fibrillation, pulmonary hypertension, or cardiac decompensation. RESULTS A total of 56,577 individuals (median age 68 years, 67% female) with asymptomatic MR were identified. At 10 years, MR-related complications were more frequent in the study group vs. control group (46.5% vs. 20.8%, OR 3.31, P < 0.0001). Furthermore, MR-related complications were more common in male vs. female patients with an asymptomatic MR (OR 2.65, P < 0.0001). The occurrence of at least one MR-related complication was associated with a reduced 10-year survival (OR 1.80, P < 0.0001). CONCLUSIONS Almost half of patients with asymptomatic MR experience complications during a 10 year follow-up which result in impaired survival. These results imply the necessity of long-term disease management program. Furthermore, decision-making process and timing for mitral valve intervention in asymptomatic patients should be reevaluated.

Abstract
BACKGROUND The COVID-19 pandemic developed its full destructive capacity in 2020. This retrospective study aimed to examine the effects of COVID-19 on the mortality and the clinical characteristics in PAD patients with COVID-19 compared to PAD patients without COVID-19. METHODS AND RESULTS Data derived from a German nationwide register of the year 2020 which encompassed all hospitalized patients with PAD (n = 173.075); N = 2553 also suffered from a COVID-19 infection and had significantly higher mortality rates of 11.2%. PAD + COVID-19 patients presented more clinical complications like major amputations (11.59%), myocardial infarction (2.08%), cardiogenic shock (2.98%), chronic kidney failure with GFR<= 15 mL/min (5.33%) and prolonged ventilation time >48 h (3.37%). Rates of pulmonary thromboembolism (0.24%), myocardial infarction (2.08%), and stroke (1.02%) were low in patients with PAD + COVID-19. Adjusted regression analyses for risk differences revealed possible causes of higher mortality rates, such as prolonged ventilation time, pneumonia, major amputations, multiple organ system failure, and length of hospital stay in patients with severe PAD (Rutherford 5-6) + COVID-19. CONCLUSION Pneumonia and major amputations were associated with high mortality rates in PAD + COVID-19 in 2020. However, we could not detect a relevant influence of pulmonary thromboembolism, myocardial infarction or stroke on higher death rates of PAD + COVID-19.

Abstract
OBJECTIVE Bypass surgery plays a key role in complex lower limb lesions. However, there is a lack of evidence regarding the management of symptomatic prosthetic bypass graft (PBG) occlusion. This study aimed to report outcomes following open, hybrid, or endovascular management of patients presenting with symptomatic PBG occlusion. METHODS A multicentre, retrospective cohort study was conducted, including patients presenting with PBG occlusion between January 2014 and December 2021 from 18 centres. It assessed the comparative value of treatment strategies, including (1) recanalisation of native vessels, (2) endovascular treatment of the failed PBG, (3) hybrid treatment, and (4) open surgery. The primary outcome measure was amputation free survival (AFS, time to major amputation and or death), whereas all cause mortality, major amputation, PBG re-occlusion, target lesion revascularisation (TLR), and Rutherford category (RC) improvement during follow up were considered as secondary endpoints. RESULTS Of 260 patients with occluded PBGs, 108 (41.5%) were treated endovascularly (24 [22.2%] by recanalisation of native vessels and 84 [77.7%] by PBG re-opening), 57 (21.9%) underwent hybrid revascularisation, and 58 (22.3%) had surgery. In addition, 27 (10.4%) were treated conservatively and 10 (3.8%) received systemic thrombolysis. With a median follow up of 1.4 (0.6 - 3.0) years, AFS was 95.5%, 76.4%, 45.5%, and 37.1%, respectively in Groups 1 - 4 (p = .007). Older age and non-endovascular treatment (HR 1.05 and 1.70; p < .01 for both) were independent predictors of poor AFS. Endovascular treatment was associated with lower rates of major amputation (p = .04), PBG re-occlusion (p < .001), and TLR (p = .037), and higher RC improvements (p < .001), whereas all cause mortality was comparable between treatment groups (p = .21). CONCLUSION Endovascular treatment is associated with higher rates of AFS and RC improvement and lower rates of PBG re-occlusion and TLR in patients with PBG occlusion.

Abstract
Aim The aim of this study is to explore the association between red blood cell distribution width-to-albumin ratio (RAR) and the risk of peripheral artery disease (PAD) in patients with diabetes. Methods This cross-sectional study extracted the data of 1,125 participants with diabetes from the National Health and Nutrition Examination Survey database. A weighted univariable logistic regression model was used to explore variables associated with PAD. With PAD as the outcome variable, a weighted logistic regression model was established. The odds ratio (OR) and 95% confidence interval (CI) were effect size. Results After adjusting for covariates, the risk of PAD in patients with diabetes was observed in those with higher RAR (OR = 1.83; 95% CI: 1.06-3.15). In addition, RAR ≥3.25 was related to increased risk of PAD in patients with diabetes (OR = 2.04; 95% CI: 1.05-3.95). In people with diabetes aged ≥65, RAR was a risk factor for PAD with an OR value of 2.67 (95% CI: 1.30-5.46). RAR ≥3.25 was associated with increased risk of PAD (OR = 3.06; 95% CI: 1.15-8.11) relative to RAR <2.80. In people with diabetes who smoked, the risk of PAD was elevated in those with RAR ≥3.25 (OR = 2.85; 95% CI: 1.28-6.32). As for patients with cardiovascular disease, the risk of PAD was elevated as the increase of RAR (OR = 2.31; 95% CI: 1.05-5.10). RAR ≥3.25 was correlated with increased risk of PAD (OR = 3.75; 95% CI: 1.42-9.87). The area under the curve of RAR for the risk of PAD in patients with diabetes was 0.631 (95% CI: 0.588-0.675). Conclusion A higher RAR was related to increased risk of PAD in patients with diabetes. The findings might offer a reference for the management of PAD in patients with diabetes.

Abstract
Background: Peripheral artery disease (PAD) frequently leads to hospital admission. Sex related differences in in-patient care are a current matter of debate. Patients and methods: Data were provided from the German national in-patient sample provided by the Federal Bureau of Statistics (DESTATIS). Trends on risk profiles, therapeutic procedures, and outcomes were evaluated from 2014 until 2019 stratified by sex and PAD severity. Results: Two-thirds of an annual >191,000 PAD in-patient cases applied to male sex. Chronic limb-threatening ischemia (CLTI) was recorded in 49.6% of male and 55.2% of female cases (2019). CLTI was as a major risk factor of in-hospital amputation (OR 229) and death (OR 10.5), whereas endovascular revascularisation (EVR) with drug-coated devices were associated with decreased risk of in-hospital amputation (OR 0.52; all p<0.001). EVR applied in 47% of CLTI cases compared to 71% in intermittent claudication (IC) irrespective of sex. In-hospital mortality was 4.3% in male vs. 4.8% in female CLTI cases, minor amputations 18.4% vs. 10.9%, and major amputation 7.5% vs. 6.0%, respectively (data 2019; all p<0.001). After adjustment, female sex was associated with lower risk of amputation (OR 0.63) and death (OR 0.96) during in-patient stay. Conclusions: Male PAD patients were twice as likely to be admitted for in-patient treatment despite equal PAD prevalence in the general population. Among in-patient cases, supply with invasive therapy did not relevantly differ by sex, however is strongly reduced in CLTI. CLTI is a major risk factor of adverse short-term outcomes, whereas female sex was associated with lower risk of in-patient amputation and/or death.

Epidemiological Trends and Projections of Incidence, Prevalence, and Disease Related Mortality Associated With Peripheral Arterial Disease: Observations Using Nationwide Danish Data. Eur J Vasc Endovasc Surg 2023; 66:662-669.

Abstract
OBJECTIVE Peripheral arterial disease (PAD) trends remain unclear because contemporary data are sparse and conflicting. This nationwide cohort study quantified changes in PAD incidence, prevalence, and all cause mortality, and projected prevalence development through to 2040. METHODS Population based registries covering the entire Danish population aged ≥ 40 years from 2000 to 2018 were linked to assess trends in PAD incidence, prevalence, and all cause mortality, overall and by sex and age groups. Based on observed trends in incidence and mortality, and estimated future annual age distribution and population mortality, the PAD prevalence through to 2040 was projected. RESULTS The Danish population aged 40 - 99 years in 2000 - 2018 included 4 811 281 individuals, among whom 145 870 incident PAD diagnoses were identified. The age and sex standardised PAD incidence decreased from 2.26 per 1 000 person years in 2000 to 1.65 in 2018 (incidence RR 0.74, 95% CI 0.72 - 0.77). The incidence was approximately 20% higher in men than women but declined similarly over time. Concurrently, PAD prevalence in the Danish adult population increased from 1.3% to 1.6% (prevalence ratio 1.28, 95% CI 1.26 - 1.30). Among patients aged ≥ 80 years, the prevalence reached 5.7% in women and 7.9% in men. The age and sex standardised annual mortality among patients with PAD decreased from 9.8% in 2000 to 7.2% in 2018 (mortality ratio 0.75, 95% CI 0.72 - 0.78). Projections of PAD prevalence demonstrated that the rising PAD prevalence will continue until around 2030, followed by a decline towards 2040. Among individuals aged ≥ 80 years, the prevalence was projected to plateau at 8.9% for men and 6.2% for women before declining. CONCLUSION Within an unselected nationwide population, the incidence and all cause mortality of PAD have declined over the last two decades. Concurrently, prevalence increased and is projected to increase further over the coming decade, emphasising the growing burden of this common atherosclerotic disease in ageing populations.

Abstract
Background: The quality of vascular care has significantly improved in part by the expansion of endovascular techniques for the treatment of symptomatic peripheral artery disease (PAD) in recent years. In Germany these are primarily provided by the three disciplines of vascular surgery, angiology, and interventional radiology (IR). However, the relative contribute of angiologists to the total number of cases performed is unknown. Patients and methods: In the present study, we analysed the respective contribution of vascular surgery, angiology, and IR to the delivery of endovascular revascularisations in symptomatic PAD in Germany based on the legally mandatory quality reports representative for the reporting year 2018. Results: Vascular surgery is the most common speciality reporting procedures in German hospitals (n=579; 25.1%), followed by IR (n=264; 11.5%), angiology (n=189; 8.2%) and cardiology (n=17; 0.7%). The combination of vascular surgery and IR was reported in 202 (8.8%), vascular surgery and angiology in 167 (7.2%) and angiology and IR in 65 (2.8%) hospitals, and 63 (2.7%) hospitals reported the combination of all three disciplines. Not every department performed catheter interventions. The analysis of procedures per centre revealed that angiology centres provided the highest numbers for both basic procedures and more complex techniques such as atherectomy, rotational thrombectomy, lithoplasty, selective thrombolysis or the use of re-entry devices. In total, angiology centres provided 24.4% of the total procedures or 23.9% of the so-called basic procedures as a surrogate for patient numbers. Conclusions: While each of the disciplines contribute significantly to the endovascular procedures, angiology centres perform more procedures per centre and more complex procedures than the other disciplines highlighting the important quantitative and qualitative contribution of angiology specialists to the care of vascular patients. The inpatient catheter interventional care of patients with PAD is still too rarely carried out in a multi-disciplinary manner in Germany.

[PMID: 37121388 DOI: 10.1016/j.ejvs.2023.04.026] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 03/31/2023] [Accepted: 04/24/2023] [Indexed: 05/02/2023]
Abstract
OBJECTIVE Antithrombotic strategies are currently recommended for the treatment of lower extremity artery disease (LEAD) but specific scores to assess the risk of bleeding in these patients are scarce. To fill the gap, the OAC3-PAD bleeding score was recently developed and validated in German cohorts. The aim of this study was to determine whether this score performs appropriately in another real world nationwide cohort. METHODS This 10 year retrospective, multicentre study based on French national electronic health data included patients who underwent revascularisation for LEAD between January 2013 and June 2022. The OAC3-PAD score was calculated and from this, the population was classified into four groups: low, low to moderate, moderate to high and high risk. A binary logistic regression model was applied, with major bleeding occurring at one year (defined using the International Classification of Diseases ICD-10) as the dependent variable. The performance of the OAC3-PAD bleeding score was investigated using a receiver operating characteristic curve. RESULTS Among 161 205 patients hospitalised for LEAD treatment in French institutions, the one year incidence of major bleeding was 13 672 patients (8.5%). The distribution of the population according to the OAC3-PAD bleeding score was: 88 835 patients (55.1%), 34 369 (21.3%), 27 914 (17.3%), and 10 087 (6.3%) in the low, low to moderate, moderate to high, and high risk groups, respectively; with an incidence of one year major bleeding of 5.0%, 9.8%, 13.2%, and 21.3%. The OAC3-PAD model achieved an AUC of 0.650 to predict one year major bleeding following LEAD repair (95% CI 0.645 - 0.655), with a sensitivity of 0.67 and a specificity of 0.57. CONCLUSION This nationwide analysis confirmed the accuracy of the OAC3-PAD model to predict one year major bleeding and served as external validation. Although further studies are required, it adds evidence and perspectives to further generalise its use to guide the management of patients with LEAD.

Limb Related Outcomes of Endovascular vs. Open Surgical Revascularisation in Patients with Peripheral Arterial Occlusive Disease: A Report from the Prospective GermanVasc Cohort Study. Eur J Vasc Endovasc Surg 2023; 66:85-93. [PMID: 36972814 DOI: 10.1016/j.ejvs.2023.03.040] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2022] [Revised: 03/01/2023] [Accepted: 03/23/2023] [Indexed: 03/28/2023]
Abstract
OBJECTIVE The goal of this study was to compare clinical outcomes in patients with peripheral arterial occlusive disease undergoing revascularisation by peripheral endovascular intervention (EVI), bypass surgery, endarterectomy (EA), and hybrid surgery in an unselected real world setting. METHODS This was a German, prospective, multicentre, comparative cohort study, enrolling patients at hospital admission for revascularisation at 35 vascular centres with 12 months of follow up. Primary composite endpoints were major amputation or death, major adverse limb events, and any minor or major amputation. Twelve month incidences and hazard ratios (HRs) for the four subgroups and 95% confidence intervals (CIs) were estimated using Kaplan-Meier functions and Cox proportional hazard models. Sociodemographic and clinical characteristics, pharmacological treatment, and comorbidities were used to adjust for patient differentials (unique identifier ClinicalTrials.gov: NCT03098290). RESULTS In total, 4 475 patients were analysed (mean age 69 years, 69.4% males, and 31.5% suffering from chronic limb threatening ischaemia). After 12 months of follow up, 5.3% (95% CI 3.6 - 6.9%) of the patients experienced either death or major amputation, 7.2% (95% CI 4.8 - 9.6%) major adverse limb event, and 6.6% (95% CI 5.0 - 8.2%) any minor or major amputation. Compared with EVI, bypass surgery was associated with an increased risk of amputation or death (HR 2.59, 95% CI 1.75 - 3.85), major adverse limb event (HR 1.93, 95% CI 1.11 - 3.36), and any minor or major amputation (HR 2.12, 95% CI 1.42 - 3.16), and hybrid surgery with an increased risk of amputation or death (HR 2.29, 95% CI 1.27 - 4.13) and major adverse limb event (HR 1.62, 95% CI 1.03 - 2.54). After adjusting for patient differentials, no significant differences among study groups remained. CONCLUSION More favourable outcomes after EVI were completely attributed to differentials in patient characteristics and not procedure type. The current study emphasised that all competing approaches performed similarly in a real world setting.

Abstract
Background and Objectives: The primary objective of this study was to investigate the incidence of lower extremity amputations (LEAs) in a representative population from Romania, in both diabetic and non-diabetic adults, including trauma-related amputations. The secondary objective was to evaluate the trends in LEAs and the overall ratio of major-to-minor amputations. Material and Methods: The study was retrospective and included data from the Romanian National Hospital Discharge Records, conducted between 1 January 2015 and 31 December 2019. Results: The overall number of cases with LEAs was 88,102, out of which 38,590 were aterosclerosis-related LEAs, 40,499 were diabetes-related LEAs, and 9013 were trauma-related LEAs, with an ascending trend observed annually for each of these categories. Of the total non-traumatic amputations, 51.2% were in patients with diabetes. Most LEAs were in men. The total incidence increased from 80.61/100,000 in 2015 to 98.15/100,000 in 2019. Conclusions: Our study reported a 21% increase in total LEAs, 22.01% in non-traumatic LEAs, and 19.65% in trauma-related amputation. The minor-to-major amputation ratio increased over the study period in patients with diabetes. According to these findings, it is estimated that currently, in Romania, there is one diabetes-related amputation every hour and one non-traumatic amputation every 30 min.

Abstract
Background: To determine the physician's perspective and perception on walking exercise as well as barriers in guideline-directed best medical treatment of patients with lower extremity peripheral arterial disease (PAD). Patients and methods: All members of the German Society for Vascular Surgery and Vascular Medicine and of the German Society for Angiology - Society for Vascular Medicine with valid email address were invited to participate in an electronic survey on walking exercise for treatment of intermittent claudication that was developed by the authors. Results: Amongst 3910 invited participants, 743 (19%) provided valid responses (33% females, 84% vascular surgery, 15% angiology). Thereof, 65% were employed by non-university hospitals, 16% by university institutions, and 18% by outpatient facilities. A mean of 14 minutes were spent per patient to counsel and educate, while only 53% responded they had enough time in everyday clinical practice. While 98% were aware of the beneficial impact of structured exercise training (SET) on pain free walking distance and 90% advise their patients to adhere to SET, only 44% provided useful guidance to patients to find local SET programmes and merely 42% knew how to prescribe SET as service that can be reimbursed by medical insurances. Approximately 35% knew a local SET programme and appropriate contact person. Health-related quality of life was assessed in a structured way by only 11%. Forty-seven percent responded that medical insurances should be responsible to implement and maintain SET programmes, while only 4% held hospital physicians responsible to achieve this task. Conclusions: This nationwide survey study amongst vascular specialists illustrates the current insufficient utilisation of SET as an evidence-based therapeutic cornerstone in patients with lower extremity PAD in Germany. The study also identified several barriers and flaws from the physician's perspectives which should be addressed collectively by all health care providers aiming to increase the SET use and eventually its' impact on patients with PAD.

Abstract
OBJECTIVE There is a paucity of current figures on the prevalence of carotid and lower extremity peripheral arterial disease (PAD) and abdominal aortic aneurysm (AAA) as well as the associated cardiovascular risk factors to support considerations on screening programmes. METHODS In the population based Hamburg City Health Study, participants between 45 and 74 years were randomly recruited. In the current cross sectional analysis of the first 10 000 participants enrolled between February 2016 and November 2018, the prevalence of carotid artery disease (intima-media thickness ≥ 1 mm), lower extremity PAD (ankle brachial index ≤ 0.9), and AAA (aortic diameter ≥ 30 mm) was determined. Multivariable logistic regression models were applied to determine the association between vascular diseases and risk factors. To account for missing values, multiple imputation was performed. RESULTS A total of 10 000 participants were analysed (51.1% females, median age 63 years, median body mass index 26.1 kg/m2). In medians, the intima media thickness was 0.74 mm (interquartile range [IQR] 0.65 - 0.84), the ankle brachial index 1.04 (IQR 0.95 - 1.13), and the aortic diameter 17.8 mm (IQR 16.1 - 19.6). Concerning risk factors, 64% self reported any smoking, 39% hypertension, 5% coronary artery disease, 3% congestive heart failure, 5% atrial fibrillation, and 3% history of stroke or myocardial infarction, respectively. In males, the prevalence of carotid artery disease, lower extremity PAD, and AAA were 35.3%, 22.7%, and 1.3%, respectively, and in females, 23.4%, 24.8%, and 0.2%, respectively. Higher age and current smoking were likewise associated with higher prevalence while the impact of variables varied widely. CONCLUSION In this large population based cohort study of 10 000 subjects from Hamburg, Germany, a strikingly high prevalence of PAD was revealed. Almost 45% suffered from any index disease, while AAA was only diagnosed in 1.3% of males and 0.2% of females. The high prevalence of atherosclerotic disease and associated cardiovascular risk factors underline that it is essential to increase awareness and fuel efforts for secondary prevention.

Abstract
PURPOSE Coronary artery disease (CAD) and peripheral artery disease (PAD) are highly prevalent in society. This nationwide analysis aimed to evaluate the trends of in-hospital treatment of patients admitted due to PAD with and without concomitant CAD, to determine the prevalence and risk factors of concomitant CAD in patients with PAD. METHODS Using data from the German Federal Statistical Office, we included all admissions for PAD (with and without concomitant CAD) in Germany between 2009 and 2018. Baseline patient characteristics, outcomes and comorbidities were analyzed. Elixhauser comorbidity groups and the linear van Walraven comorbidity score (vWs) were calculated to assess the comorbidity burden. RESULTS Of all 1,793,517 patients hospitalized for PAD, a total of 21.8% (390,259) had concomitant CAD, increasing from 18.6% in 2009 to 24.4% in 2018. Patients with accompanying CAD showed higher in-hospital mortality (3.7 vs. 2.6%), more major amputations (9.0 vs. 7.7%) and more comorbidities (Elixhauser score: 4.2 vs. 3.2 and vWs: 9.1 vs. 6.1), resulting in higher costs (median: EUR 4541 vs. EUR 4268 per case). More advanced stages of PAD were associated with multi-vessel CAD (10% of all patients with PAD Fontaine IV showed 3-vessel CAD) and the prevalence of multi-vessel CAD increased predominantly in patients with advanced PAD. CONCLUSION One in four patients hospitalized for PAD had concomitant CAD, showing an increase over time with an additional medical and economic burden for hospitals compared with patients without CAD.

Abstract
Together with colleagues from different disciplines, including cardiologists, interventional radiologists and vascular surgeons, committee members of the of the German Society of Angiology (Deutsche Gesellschaft für Angiologie [DGA]), developed a novel algorithm for the endovascular treatment of peripheral chronic total occlusive lesions (CTOs). Our aim is to improve patient and limb related outcomes, by increasing the success rate of endovascular procedures. This can be achieved by adherence to the proposed crossing algorithm, aiding the standardization of endovascular procedures. The following steps are proposed: (i) APPLY Duplex sonography and if required 3D techniques such as computed tomography or magnetic resonance angiography. This will help you to select the optimal access site. (ii) EVALUATE the CTO cap morphology and distal vessel refilling sites during diagnostic angiography, which are potential targets for a retrograde access. (iii) START with antegrade wiring strategies including guidewire (GW) and support catheter technology. Use GW escalation strategies to penetrate the proximal cap of the CTO, which may usually be fibrotic and calcified. (iv) STOP the antegrade attempt depending on patient specific parameters and the presence of retrograde options, as evaluated by pre-procedural imaging and during angiography. (v) In case of FAILURE, consider advanced bidirectional techniques and reentry devices. (vi) In case of SUCCESS, externalize the GW and treat the CTO. Manage the retrograde access at the end of the endovascular procedure. (vii) STOP the procedure if no progress can be obtained within 3 hours, in case of specific complications or when reaching maximum contrast administration based on individual patient's renal function. Consider radiation exposure both for patients and operators. In this manuscript we systematically follow and explain each of the steps (i)-(vi) based on practical examples from our daily routine. We strongly believe that the integration of this algorithm in the daily practice of endovascular specialists, can improve vessel and patient specific outcomes.

Abstract
BACKGROUND Endovascular treatment (EVT) has replaced open repair as the first option in intermittent claudication (IC) and chronic limb-threatening ischemia (CLTI) in several centers. However, evidence of the most optimal post-procedural surveillance strategy is sparse. This study aimed to compare two routine surveillance programs after EVT of IC/CLTI: clinical and hemodynamic assessment (CHA) vs. duplex ultrasound (DUS) and clinical/hemodynamic assessment in combination. METHODS Between February 2012 and December 2015, all patients with EVT of IC/CLTI were allocated to either CHA or DUS-based routine surveillance programs. The allocation-ratio was 1:2 (CHA:DUS), and propensity score matching (PSM) was used to control baseline differences between the groups. Follow-up visits in the CHA group consisted of clinical assessment and ABI at 3, 6, 12 and 24 months. Follow-up visits in DUS group consisted of clinical assessment, ABI, and target vessel DUS at 1, 3, 6, 12, 18 and 24 months. RESULTS In total, 340 legs in 305 patients suffering from IC/CLTI were included; 111 (33%) in the CHA-group and 229 (67%) in the DUS group. The two groups were identical except for a significantly lower incidence of diabetes mellitus in the CHA group than the DUS group, 55% vs. 72%, respectively (P=006). Based on PSM, the CHA-group vs. the DUS-group was burdened of an increased risk of amputation (12.5% vs. 8.27%, HR=0.41 [95% CI: 0.17-0.96]), and a higher mortality (21.2% vs. 12.8%, HR=0.37 [95% CI: 0.19-0.72]). The reported differences in reintervention rate (7.5% vs. 12.8%, HR=1.12 [95% CI: 0.44-2.84]) were insignificant. The mean follow-up was 317 days (SD=0.214) in the CHA group and 611 days (SD=0.298) in the DUS group. CONCLUSIONS Our results suggest that DUS-based routine surveillance after EVT of IC/CLTI is superior to CHA-based routine surveillance in improved amputation rate and mortality.

Abstract
BACKGROUND Peripheral arterial disease (PAD) causes blood vessel narrowing that decreases blood flow to the lower extremities, with symptoms such as leg pain, discomfort, and intermittent claudication. PAD increases risks for amputation, poor health-related quality of life, and mortality. It is estimated that more than 200 million people worldwide have PAD, although the paucity of PAD research in the East detracts from knowledge on global PAD epidemiology. There are few national data-based analyses or health care utilization investigations. Thus, a national data analysis of PAD incidence and prevalence would provide baseline data to enable health promotion strategies for patients with PAD. OBJECTIVE This study aims to identify South Korean trends in the incidence and prevalence of PAD and PAD treatment, in-hospital deaths, and health care utilization. METHODS This was a retrospective analysis of South Korean national claims data from 2009 to 2018. The incidence of PAD was determined by setting the years 2010 and 2011 as a washout period to exclude previously diagnosed patients with PAD. The study included adults aged ≥20 and <90 years who received a primary diagnosis of PAD between 2011 and 2018; patients were stratified according to age, sex, and insurance status for the incidence and prevalence analyses. Descriptive statistics were used to assess incidence, prevalence, endovascular revascularization (EVR) events, amputations, in-hospital deaths, and the health care utilization characteristics of patients with PAD. RESULTS Based on data from 2011 to 2018, there were an average of 124,682 and 993,048 incident and prevalent PAD cases, respectively, in 2018. PAD incidence (per 1000 persons) ranged from 2.68 to 3.09 during the study period. From 2012 to 2018, the incidence rate in both sexes showed an increasing trend. PAD incidence continued to increase with age. PAD prevalence (per 1000 persons) increased steadily, from 3.93 in 2011 to 23.55 in 2018. The number of EVR events varied between 933 and 1422 during the study period, and both major and minor amputations showed a decreasing trend. Health care utilization characteristics showed that women visited clinics more frequently than men, whereas men used tertiary and general hospitals more often than women. CONCLUSIONS The number of incident and prevalent PAD cases generally showed an increasing trend. Visits to tertiary and general hospitals were higher among men than women. These results indicate the need for attention not only to Western and male patients, but also to Eastern and female patients with PAD. The results are generalizable, as they are based on national claims data from the entire South Korean population, and they can promote preventive care and management strategies for patients with PAD in clinical and public health settings.

A Delphi Consensus on Patient Reported Outcomes for Registries and Trials Including Patients with Intermittent Claudication: Recommendations and Reporting Standard. Eur J Vasc Endovasc Surg 2022; 64:526-533. [PMID: 35985529 DOI: 10.1016/j.ejvs.2022.08.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Revised: 07/14/2022] [Accepted: 08/05/2022] [Indexed: 01/12/2023]
Abstract
OBJECTIVE This study aimed to develop a core set of patient reported outcome quality indicators (QIs) for the treatment of patients with intermittent claudication (IC), that allow a broad international implementation across different vascular registries and within trials. METHODS A rigorous modified two stage Delphi technique was used to promote consensus building on patient reported outcome QIs among an expert panel consisting of international vascular specialists, patient representatives, and registry members of the VASCUNET and the International Consortium of Vascular Registries. Potential QIs identified through an extensive literature search or additionally proposed by the panel were validated by the experts in a preliminary survey and included for evaluation. Consensus was reached if ≥ 80% of participants agreed that an item was both clinically relevant and practical. RESULTS Participation rates in two Delphi rounds were 66% (31 participants of 47 invited) and 90% (54 of 60), respectively. Initially, 145 patient reported outcome QIs were documented. Following the two Delphi rounds, 18 quality indicators remained, all of which reached consensus regarding clinical relevance. The VascuQoL questionnaire (VascuQoL-6), currently the most common patient reported outcome measurement (PROM) used within vascular registries, includes a total of six items. Five of these six items also matched with high rated indicators identified in the Delphi study. Consequently, the panel recommends the use of the VascuQoL-6 survey as a preferred core PROM QI set as well as an optional extension of 12 additional patient reported QIs that were also identified in this study. CONCLUSION The current recommendation based on the Delphi consensus building approach, strengthens the international harmonisation of registry data collection in relation to patient reported outcome quality. Continuous and standardised quality assurance will ensure that registry data may be used for future quality benchmarking studies and, ultimately, positively impact the overall quality of care provided to patients with peripheral arterial occlusive disease.

Abstract
INTRODUCTION In patients with peripheral artery disease (PAD) the presence of diabetes mellitus (DM) is associated with higher morbidity and mortality. Because huge efforts are made to improve medical care of patients with DM including chronic disease programs, the aim of the present study was to investigate temporal trends regarding the clinical burden of DM on PAD patients within a 15-year observational period. METHODS We analyzed all patients hospitalized because of PAD between 2005 and 2019 in Germany stratified regarding DM. RESULTS Overall, 2 654 871 hospitalizations of PAD patients (865 823 with DM) were included. Hospitalizations based on PAD inclined from 142 778 in 2005 to 190 135 in 2019 (β 3956 per year; 95% confidence interval [CI] 3034-4878, p < .001) with simultaneous increase of hospitalizations of PAD patients with DM (2005: 41609 (29.1%) versus 2019: 65 302 (34.3%); β 2019 per year [95% CI 1593-2446], p < .001). Amputation rates (β -0.42 [95% CI -0.44 to -0.40]; p < .001) as well as in-hospital case-fatality rate (2005: 4.7%, 2019: 2.8%; β -0.64 [95% CI -0.69 to -0.59]; p < .001) decreased in diabetic PAD patients during the observational time. In spite of improved morbidity and mortality in the last years of the observational period, patients with DM still suffered from an increased risk for morbidity and mortality during the observational period compared to nondiabetic PAD patients. CONCLUSIONS Despite the progress in DM treatments, DM still was associated with an unfavorable clinical patient profile and remained a substantial risk factor for morbidity and mortality in hospitalized patients with PAD and DM in Germany between 2005 and 2019.

Abstract
BACKGROUND Studies from Denmark and the USA have shown differences in treatment outcomes for patients with peripheral arterial occlusive disease (PAOD) between hospitals of different size and certification status. For Germany, it is not known whether certification as a specialist center for vascular diseases or hospital size is associated with differences in the primary treatment outcome. METHODS Using data from the German Federal Statistical Office, all hospitalizations due to PAOD of Fontaine stage IIb or higher were included in our study and the hospitals were classified according to their size and certification status. PAOD stage, age, sex, and comorbidities were documented for each hospitalization. Univariate and multivariate logistic regressions were performed to identify independent variables that predict various treatment endpoints. RESULTS A total of 558 785 hospitalizations were included for analysis, of which 29% were in hospitals with certified vascular centers. In multivariate analysis, admissions to certified hospitals were associated with lower rates of major amputation (odds ratio [OR] 0.95, 95% confidence interval [0.92; 0.98], p = 0.003) and higher rates of minor amputation (OR 1.04 [1.01; 1.06], p = 0.004) with no difference observed in mortality (OR 0.99 [0.96; 1.03], p = 0.791). Admissions to larger hospitals were associated with more comorbidities, longer hospital stays, and higher rates of mortality and amputations. CONCLUSION Treatments in certified hospitals are associated with fewer major and more minor amputations. This may reflect intensification of therapy targeting preservation of functional limbs.

Antithrombotic Treatment Patterns of Patients with Symptomatic Peripheral Arterial Occlusive Disease in Germany: Evidence from Health Insurance Claims Data. J Clin Med 2022; 11:jcm11185455.

Abstract
Objectives: Patients with peripheral arterial occlusive disease (PAOD) are at risk of worsening limb symptoms, major adverse cardiovascular events and exhibit an impaired life expectancy. There is a lack of evidence on the extent of pharmacological secondary prevention in PAOD patients. This study assesses treatment patterns of antithrombotic agents in symptomatic PAOD patients. Methods: This is a retrospective cohort study using data from the second largest insurance fund in Germany, BARMER. We included symptomatic PAOD patients undergoing in-hospital treatment with an index admission between 1 January 2010 and 31 December 2017. Outcomes were proportions of single antiplatelets (SAPT), dual antiplatelets (DAPT), vitamin-K antagonists (VKA), or direct oral anticoagulants (DOAC) in the 12 months prior and 6 months after the index hospitalization. Non-parametric cumulative incidence for competing risks was estimated to account for censoring and death after discharge from hospital stay. Patient flows were visualised by alluvial diagrams. All analyses were stratified by intermittent claudication (IC) and chronic limb-threatening ischaemia (CLTI). The protocol was registered to ClinicalTrials.gov (NCT03909022). Results: A total of 80,426 unique patient encounters were identified. Mean age was 72.7 (46.3% female). Amongst all patients, 25.6% were on SAPT, 4.1% on DAPT, 9.1% on VKA, 3.9% on DOAC, 3.9% on both antiplatelets and oral anticoagulation, and 53.3% without any antithrombotic therapy during the 12 months before index stay. The estimated cumulative incidence was 37.9% SAPT, 14.8% DAPT, 7.5% VKA, 4.3% DOAC, 7.4% both, and 28.1% without any antithrombotic therapy during the 6 months after index stay. The considerable increases in antiplatelet therapy were mainly driven by the group of patients without antithrombotics before index stay. As compared with IC, patients who suffered from CLTI received less often antiplatelets but more often anticoagulants both before and after index stay. Conclusions: Utilisation rates of antithrombotic therapy increased considerably after in-hospital treatment for PAOD. Yet, remarkably high rates of symptomatic patients without any blood-thinning therapy constitute a major concern with respect to adequate secondary prevention of PAOD patients.

Abstract
BACKGROUND Endovascular atherectomy enables minimally invasive plaque removal in peripheral artery disease (PAD). AIMS We aimed to evaluate the safety and the long-term effectiveness of the Phoenix atherectomy for the treatment of complex and calcified lesions in PAD patients. METHODS Consecutive all-comer patients with PAD underwent the Phoenix atherectomy. Device safety in terms of perforation and distal embolisation were evaluated. Lesion calcifications were categorised by the Peripheral Arterial Calcium Scoring System (PACSS) and lesion complexity was assessed by the Transatlantic Inter-Society Consensus (TASC). Clinically driven target lesion revascularisation (TLR) was assessed. RESULTS A total of 558 lesions were treated in 402 consecutive patients. Clinical follow-up was available at 15.7±10.2 months for 365 (91%) patients. Of 402 patients, 135 (33.6%) had claudication, 37 (9.2%) had ischaemic rest pain and 230 (57%) exhibited ischaemic ulcerations. Lesions were mostly identified in the femoropopliteal segments (55%), followed by below-the-knee (BTK) segments (32%). Complex TASC C/D lesions and moderate to severe calcifications (PACSS score ≥2) were present in 331 (82%) and 323 (80%) patients, respectively. The mean lesion length was 20.6±14.3 cm. Five (1%) perforations and 10 (2%) asymptomatic embolisations occurred. Bail-out stenting was performed in 4%, 16% and 3% of patients with common femoral artery, femoropopliteal and BTK lesions, respectively. During follow-up, 5 (3.9%) patients with claudication and 52 (21.9%) patients with critical limb-threatening ischaemia (CLTI) died (hazard ratio [HR] 3.7; p<0.001). Freedom from TLR was 87.5% (112 of 128) in patients with claudication and 82.3% (195 of 237) in patients with CLTI, respectively (HR 1.8; p=0.03). CONCLUSIONS The Phoenix atherectomy can be safely performed in patients with complex lesions with a relatively low rate of bail-out stenting and clinically acceptable TLR rates.

Abstract
Obwohl Patient:innen mit einer peripheren arteriellen Verschlusskrankheit (PAVK) aufgrund ihres Komorbiditäts- und Risikoprofils ein insgesamt erhöhtes Blutungsrisiko aufweisen, standen bisher keine validierten Werkzeuge zur Vorhersage des Blutungsrisikos zur Verfügung. Erschwerend kommt hinzu, dass viele randomisierte und kontrollierte Studien zu antithrombotischen Therapien Patient:innen mit erhöhtem Blutungsrisiko ausgeschlossen haben. Anhand von Routinedaten der Krankenkasse wurde mittels Verfahren des maschinellen Lernens ein pragmatisches Vorhersagemodell entwickelt und intern validiert. Mit dem OAC3-PAD-Risikoscore wurden acht Variablen identifiziert, die das Risiko von schweren Blutungsereignissen innerhalb eines Jahres nach stationärer Behandlung der PAVK vorhersagen können. Dieser Risikoscore kann dabei helfen, eine patientenzentrierte Risiko-Nutzen-Abwägung durchzuführen, um das maximale Potenzial aus den verfügbaren antithrombotischen Therapiestrategien zu schöpfen.

OBJECTIVE For peripheral artery disease (PAD) patients, after endovascular revascularization, it is crucial to manage associated factors that can affect the risk of major adverse events. We aimed to investigate the associated factors of major adverse events in these patients. MATERIALS AND METHODS We conducted a retrospective longitudinal analysis using the electronic medical records from a tertiary hospital in Korea and included the data of 1263 patients. Eligible patients were categorized into four groups based on diabetes mellitus (DM) and regular exercise. The major adverse events included major adverse limb events and major adverse cardiovascular events. Major adverse events-free survival was assessed using the Kaplan-Meier method, and associated factors of major adverse events were analyzed using Cox proportional hazards analyses. RESULTS Kaplan-Meier survival curves showed that patients with DM and non-regular exercise had a shorter major adverse events-free survival. The Cox regression analysis showed that for patients with critical limb ischemia or chronic kidney disease, the risk of major adverse events increased, while group variables were not significant. CONCLUSION Target management of patients with DM, critical limb ischemia, and chronic kidney disease is essential to reduce major adverse events after endovascular revascularization in patients with PAD.

GERMAN MEDICAL SCIENCE : GMS E-JOURNAL 2022; 20:Doc02. [PMID: 35465639 PMCID: PMC9006313 DOI: 10.3205/000304] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/19/2021] [Revised: 09/22/2021] [Indexed: 11/30/2022]
Abstract
Introduction: This study investigates the runtime and costs of biventricular defibrillators (CRT-D) and biventricular pacemakers (CRT-P). Accurate estimates of cardiac resynchronization therapy (CRT) device runtime across all manufactures are rare, especially for CRT-P. Methods: Health claims data of a large nationwide German health insurance was used to analyze CRT device runtime. We defined device runtime as the time between the date of implantation and the date of generator change or removal. The median costs for implantation, change, and removal of a CRT device were calculated accordingly. Results: In total, the data set comprises 17,826 patients. A total of 4,296 complete runtimes for CRT-D devices and 429 complete runtimes for CRT-P devices were observed. Median device runtime was 6.04 years for CRT-D devices and 8.16 years for CRT-P devices (log-rank test p<0.0001). The median cost of implantation for a CRT-D device was 14,270 EUR, and for a CRT-P device 9,349 EUR. Conclusions: Compared to CRT-P devices, CRT-D devices had a significantly shorter device runtime of about two years. Moreover, CRT-D devices were associated with higher cost. The study provides important findings that can be utilized by cost-effectiveness analyses.

Abstract
Objective To analyze trends and differences of endovascular, surgical and hybrid revascularization approaches and the impact of comorbidity on characteristics, costs, and outcome of in-patients with peripheral artery disease (PAD) of the lower extremity. Methods Analyzing data provided by the Research Data Center of the German Federal Statistical Office, we included all hospitalizations due to PAD Fontaine IIb (Rutherford 2–3) or higher in Germany between 2009–2011 and 2016–2018. According to the individually performed procedures encoded by the Operation and Procedure Classification System, we divided hospitalizations by revascularization procedures into sole endovascular, sole surgical, hybrid, two-step and no revascularization. Patient’s comorbidity was assessed using the linear van Walraven comorbidity score (vWs). Results 1,067,671 hospitalizations (mean age 71.3 ± 11.1 years; 60.1% male) were analyzed. Between 2009–2011 and 2016–2018, reimbursement costs rose by 28.0% from €2.72 billion (€5,350/case) to €3.49 billion (€6,238/case). The share of hospitalizations with any revascularization increased by 8.9% (67.7–73.7%) driven by an increase in two-step (+ 63.3%), hybrid (+ 58.2%) and sole endovascular revascularizations (+ 32.6%), while sole surgical approaches declined (− 18.2%). Hospitalizations of more comorbid patients (vWs ≥ 20) rose by 46.8% (21,444–31,478 cases), showed an overproportionate increase in costs of 124.6% (+ €1,750/case) and were associated with more individual procedures (+ 90.6%). Conclusions In-patient treatment of PAD patients shows increasing numbers of hybrid and sole endovascular revascularizations and more patients with higher comorbidity, while sole surgical interventions and in-hospital mortality decrease. Consequently, associated costs are surging especially in more comorbid patients due to an increasing number of performed procedures and escalation of therapy.

Utilization and Regional Differences of In-Patient Services for Peripheral Arterial Disease and Acute Limb Ischemia in Germany: Secondary Analysis of Nationwide DRG Data. J Clin Med 2022; 11:2116. [PMID: 35456207 PMCID: PMC9025059 DOI: 10.3390/jcm11082116] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2022] [Revised: 04/02/2022] [Accepted: 04/09/2022] [Indexed: 01/02/2023] Open
Abstract
BACKGROUND Peripheral arterial disease (PAD) and acute limb ischemia (ALI) pose an increasing strain on health care systems. The objective of this study was to describe the German health care landscape and to assess hospital utilization with respect to PAD and ALI. METHODS Secondary data analysis of diagnosis-related group statistics data (2009-2018) provided by the German Federal Statistical Office. Inclusion of cases encoded by the International Classification of Diseases (ICD-10) codes for PAD and arterial embolism or thrombosis. Construction of line diagrams and choropleth maps to assess temporal trends and regional distributions. RESULTS A total of 2,589,511 cases (median age 72 years, 63% male) were included, of which 2,110,925 underwent surgical or interventional therapy. Overall amputation rate was 17%, with the highest rates of minor (28%) and major amputations (15%) in patients with tissue loss. In-hospital mortality (overall 4.1%) increased in accordance to Fontaine stages and was the highest in patients suffering arterial embolism or thrombosis (10%). Between 2009 and 2018, the annual number of PAD cases with tissue loss (Fontaine stage IV) increased from 97,092 to 111,268, whereby associated hospital utilization decreased from 2.2 million to 2.0 million hospital days. Hospital incidence and hospital utilization showed a clustering with the highest numbers in eastern Germany, while major amputation rate and mortality were highest in northern parts of Germany. CONCLUSIONS Increased use of endovascular techniques was observed, while hospital utilization to treat PAD with tissue loss has decreased. This is despite an increased hospital incidence. Addressing socioeconomic inequalities and a more homogeneous distribution of dedicated vascular units might be advantageous in reducing the burden of disease associated with PAD and ALI.

Abstract
Background Due to an increasing life expectancy, more and more patients experience the failure of peripheral arterial revascularization. This study aims to investigate patients treated for the failure of infra-inguinal bypass grafts, and to investigate the interaction of different bypass materials [great saphenous vein (GSV) and polytetrafluoroethylene (PTFE)] and the further outcome. Methods Retrospective single-center analysis of consecutive patients treated for acute or chronic occlusion of infra-inguinal bypasses at a university hospital was conducted. Hospitalizations from 1st January 2010 through 31st December 2019 were included. Perioperative parameters from the index operation including graft material (prosthetic vs. autologous) were assessed. After bypass occlusion, the grade of ischemia, as well as the distal landing zone of the redo bypass compared with the primary bypass was investigated. Results In this study, 158 (65% men and 35% women with a m mean age of 70.5 years) eligible patients were included (57% vein and 42% prosthetic bypass grafts). After graft occlusion, 47% of the patients presented with symptoms of acute limb-threatening ischemia, 53% with symptoms of chronic leg ischemia. The rate of acute limb-threatening ischemia was significantly higher when prosthetic graft material was used during the index operation (p =0.016). Additionally, in case of reoperation, the landing zone of the redo bypass was significantly more distally located after occlusion of prosthetic bypass graft (p = 0.014) Conclusion Occlusions of prosthetic bypass grafts were associated with significantly higher rates of acute symptoms compared with vein grafts. Additionally, a shift to a more distal landing zone was recognized after the failure of a prosthetic bypass graft during the redo bypass operation.

Abstract
OBJECTIVE To assess the association between long term risk of hospitalisation for heart failure (HHF) and lower extremity minor and major amputation (LEA) in patients initiating sodium glucose cotransporter 2 inhibitors (SGLT2i) suffering from type 2 diabetes and peripheral arterial disease (PAD). Outcomes were compared with patients without PAD and evaluated separately for the time periods before and after the official warning of the European Medicines Agency (EMA) in early 2017. METHODS This study used BARMER German health claims data including all patients suffering from type 2 diabetes initiating SGLT2i therapy between 1 January 2013 and 31 December 2019 with follow up until the end of 2020. New users of glucagon like peptide 1 receptor agonists (GLP1-RAs) were used as active comparators. Inverse probability weighting with truncated stabilised weights was used to adjust for confounding, and five year risks of HHF and LEA were estimated using Cox regression. Periods before and after the EMA warning were analysed separately and stratified by presence of concomitant PAD. RESULTS In total, 44 284 (13.6% PAD) and 56 878 (16.3% PAD) patients initiated SGLT2i or GLP1-RA, respectively. Before the EMA warning, initiation of SGLT2i was associated with a lower risk of HHF in patients with PAD (hazard ratio, HR, 0.85, 95% confidence interval, CI, 0.73 - 0.99) and a higher risk of LEA in patients without PAD (HR 1.79, 95% CI 1.04 - 2.92). After the EMA warning, the efficacy and safety endpoints were no longer statistically different between groups. CONCLUSION The results from this large nationwide real world study highlight that PAD patients exhibit generally high amputation risks. This study refutes the idea that the presence of PAD explains the excess LEA risk associated with initiation of SGLT2i. The fact that differentials among study groups diminished after the EMA warning in early 2017 emphasises that regulatory surveillance measures worked in everyday clinical practice.

Abstract
BACKGROUND In patients with peripheral artery disease (PAD), the impact of diabetes mellitus (DM) on patient-profile and adverse in-hospital events is not well investigated. METHODS The German nationwide inpatient sample 2005-2019 was used for this analysis. Hospitalized PAD patients were stratified for DM and the influence of DM on patient-profile and adverse in-hospital events was investigated. RESULTS Our study comprised 2,654,871 hospitalizations (54.3% aged ≥70 years, 36.7% females) of patients with PAD in Germany 2005-2019. Among these, 864,691 (32.6%) patients had DM and 76,716 (2.9%) died during hospitalization. Diabetic PAD patients revealed an aggravated cardiovascular profile (Charlson Comorbidity Index: 6.0 (5.0-8.0) vs. 4.0 (3.0-5.0), p < 0.001). PAD patients with DM showed a higher rate of in-hospital mortality (3.5% vs. 2.6%, p < 0.001), as well as major adverse cardiovascular and cerebrovascular events (MACCE, 4.7% vs. 3.3%, p < 0.001) and had more often operated with amputation surgery (16.4% vs. 9.1%, p < 0.001). DM was an independent predictor of in-hospital mortality (OR 1.077 (95%CI 1.060-1.093), p < 0.001) and MACCE (OR 1.118 (95%CI 1.103-1.133), p < 0.001). In addition, amputations were also associated with DM (OR 1.804 (95%CI 1.790-1.818)), p < 0.001). CONCLUSIONS DM is associated with an unfavorable clinical patient-profile and higher risk for adverse events in PAD patients, including substantially increased in-hospital mortality as well as MACCE rate, and were more often associated with amputation surgeries.

Abstract
OBJECTIVES To analyze trends of in-hospital treatment of patients admitted due to peripheral artery disease (PAD) from 2009 to 2018 with special focus on comorbidities, revascularization procedures, resulting costs, and outcome. METHODS Using data from the research data center of the German Federal Statistical Office, we included all hospitalizations due to PAD Fontaine stage IIb or higher from 2009 to 2018. To analyze comorbidities, Elixhauser diagnostic groups and linear van Walraven score (vWS) were assessed. RESULTS A total of 1.8 million hospitalizations resulting in €10.3 billion in reimbursement costs were included. From 2009 to 2018, the absolute number of hospitalizations due to PAD increased by 13.3% (163,547 to 185,352). The average cost per hospitalization increased by 20.8% from €5,261 to €6,356. The overall in-hospital mortality decreased from 3.1 to 2.6%. Median vWS of all PAD cases increased by 3 points (2 to 5). The number of percutaneous transluminal angioplasties (PTA) increased by 43.9% while some surgical procedures such as bypasses and embolectomies decreased by 30.8% and 6.8%, respectively. Many revascularization procedures showed a disproportionate increase of those performed in vessels below the knee for example in PTA (+ 68.5%) or in endarterectomies (+ 38.8%). CONCLUSIONS This decade-long nationwide analysis shows a rising number of hospitalizations due to PAD with more comorbid patients resulting in increasing reimbursement costs. Interventions are shifting from surgical to endovascular approaches with a notable trend towards interventions in smaller vessels below the knee. KEY POINTS • The number of hospitalizations due to peripheral artery disease is rising and it is associated with increasing reimbursement costs. • Admitted patients are older and show an increasing number of comorbidities while overall in-hospital mortality is decreasing. • Revascularization procedures are shifting from surgical to endovascular approaches and show a trend towards intervention in smaller vessels below the knee. • Major amputations are decreasing while the number of minor amputations is increasing.

Quiescent-Interval Slice-Selective MRA Accurately Estimates Intravascular Stent Dimensions Prior to Intervention in Patients With Peripheral Artery Disease. J Magn Reson Imaging 2021; 55:246-254. [PMID: 34323329 DOI: 10.1002/jmri.27864] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2021] [Revised: 07/15/2021] [Accepted: 07/16/2021] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Quiescent-interval slice-selective (QISS) magnetic resonance angiography (MRA) is a non-contrast alternative for the pre-procedural assessment of patients with peripheral artery disease (PAD). However, the feasibility of pre-procedural stent size estimation using QISS MRA would merit investigation. PURPOSE To evaluate the feasibility of QISS MRA for pre-procedural stent size estimation in PAD patients compared to computed tomography angiography (CTA). STUDY TYPE Retrospective. SUBJECTS Thirty-three PAD patients (68 ± 9 years, 18 men, 15 women). FIELD STRENGTH/SEQUENCE Two-dimensional balanced steady-state free precession QISS MRA at 1.5 T and 3 T. ASSESSMENT All patients received QISS MRA and CTA of the lower extremity run-off followed by interventional digital subtraction angiography (DSA). Stenotic lesion length and diameter were quantified (AMF and AVS with 3 and 13 years of experience in cardiovascular imaging, respectively) to estimate the dimensions of the stent necessary to restore blood flow in the treated arteries. Measured dimensions were adjusted to the closest stent size available. STATISTICAL TESTS The Friedman test with subsequent pairwise Wilcoxon signed-rank test was used to compare the estimated stent dimensions between QISS MRA, CTA, and the physical stent size used for intervention. Intra-class correlation (ICC) analysis was performed to assess inter-reader agreement. Significant differences were considered at P < 0.05. RESULTS No significant difference was observed between estimated stent diameter by QISS MRA or CTA compared to physical stent diameter (8.9 ± 2.9 mm, 8.8 ± 3.0 mm, and 8.8 ± 3.8 mm, respectively; χ2 = 1.45, P = 0.483). There was a significant underestimation of stent length for both QISS MRA and CTA, compared to physical stent length (45.8 ± 27.8 mm, 46.4 ± 29.3 mm, and 50.4 ± 34.0 mm, respectively; χ2 = 11.96) which could be corrected when measurements were adjusted to the next available stent length (χ2 = 2.38, P = 0.303). Inter-reader assessment showed good to excellent agreement between the readers (all ICC ≥0.81). DATA CONCLUSION QISS MRA represents a reliable method for pre-procedural lesion assessment and stent diameter and length estimation in PAD patients. LEVEL OF EVIDENCE 3 TECHNICAL EFFICACY: Stage 2.

Abstract
Background: Previous observational studies reported a wide variation and possible room for improvement in the treatment of patients suffering from symptomatic peripheral artery disease (PAD). Yet, systematic assessment of everyday clinical practice is lacking. A General Data Protection Regulation (GDPR) compliant registry was developed and used to collect comprehensive data on clinical treatment and outcomes regarding PAD in Germany. Here, we report baseline characteristics of patients prospectively enrolled until the end of 2020. Methods: The GermanVasc registry study is a prospective longitudinal multicentre cohort study. Between 1st May 2018 and 31st December 2020, invasive endovascular, open-surgical, and hybrid revascularisations of patients suffering from chronic symptomatic PAD were prospectively included after explicit informed consent (NCT03098290). For ensuring high quality of the data, we performed comprehensive risk-based and random-sample external and internal validation. Results: In total, 5608 patients from 31 study centres were included (34% females, median 69 years). On-site monitoring visits were performed at least once in all centres. The proportion of chronic limb-threatening ischaemia was 30% and 13% were emergent admissions. 55% exhibited a previous revascularisation. Endovascular techniques made 69% among all documented invasive procedures (n=6449). Thirty-five percent were classified as patients with severe systemic disease, and 3% exhibited a constant threat to life according to the American Society of Anaesthesiologists classification. The risk profile comprised of 75% former or current smokers, 36% diabetes mellitus, and in 30% a current ischemic heart disease was present. At discharge, 93% of the patients received antiplatelets and 77% received statins. Conclusions: The GermanVasc registry study provides insights into real-world practice of treatment and outcomes of 5,608 patients with symptomatic PAD in Germany. The cohort covers a broader range of disease severity and types of interventions than usually found in trials. In future studies, comparative outcomes will be analysed in more detail.

Vascular Diagnostic and Surgical Treatments Before Lower Limb Amputations in Patients with Arterial Vascular Diseases: A Population Based Study from 2013 to 2015 in Germany. Eur J Vasc Endovasc Surg 2021; 62:469-475. [PMID: 34274219 DOI: 10.1016/j.ejvs.2021.05.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 04/27/2021] [Accepted: 05/08/2021] [Indexed: 12/24/2022]
Abstract
OBJECTIVE Patients with peripheral artery disease (PAD) have an increased risk of lower limb amputation. Given the international wide variance in major amputations, the high mortality rates and follow up costs as well as the significantly reduced quality of life of patients with amputations, vascular diagnostics and vascular surgery treatments are of great importance for lower limb preservation in patients with PAD. This study examines these guideline based procedures in patients before a first lower limb amputation and PAD. METHODS This was a retrospective longitudinal study. Data from a large German statutory health insurance scheme were examined on patients with first amputation of lower extremities and PAD between 2013 and 2015 (incidence). Pre-defined vascular diagnostic and vascular surgical procedures were considered, as specified by guidelines within inpatient and outpatient care in a defined time before lower limb amputation. RESULTS The overall estimated incidence of lower extremity amputations in the total population was 0.12% from 2013 to 2015. Of these, 51.7% had PAD; 81.8% of patients received at least one vascular diagnostic measure and 61.0% a vascular surgery procedure before the lower extremity amputation. There were only minor variations in the use of diagnostic or surgical treatments between patients with major and minor amputation. In total, 63.9% of patients had vascular surgery before the incident major amputation compared with 60.0% of patients with a minor amputation. Noticeable regional differences were found ranging from 91% (Berlin) to 67% (Bremen) regarding diagnostic procedures provided before amputation, and from 83% (Hamburg) to 55% (Saxony-Anhalt) regarding vascular surgery before amputations. CONCLUSION Of patients with PAD, 18.2% did not receive a vascular diagnostic examination before amputation as specified in the guidelines, which reflects an underuse of health services. In one third of patients who did not receive vascular surgery, major amputation probably could have been avoided.

Sex Disparities in Long-Term Mortality after Paclitaxel Exposure in Patients with Peripheral Artery Disease: A Nationwide Claims-Based Cohort Study. J Clin Med 2021; 10:2978. [PMID: 34279461 PMCID: PMC8268810 DOI: 10.3390/jcm10132978] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Revised: 06/28/2021] [Accepted: 06/30/2021] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Randomized controlled trials have reported excess mortality in patients treated with paclitaxel-coated devices versus uncoated devices, while observational studies have reported the opposite. This study aims to determine the underlying factors and cohort differences that may explain these opposite results, with specific focus on sex differences in treatment and outcomes. METHODS Multicenter health insurance claims data from a large insurance fund, BARMER, were studied. A homogeneous sample of patients with an index of endovascular revascularization for symptomatic peripheral arterial occlusive disease between 2013 and 2017 was included. Adjusted logistic regression and Cox regression models were used to determine the factors predicting allocation to paclitaxel-coated devices and sex-specific 5-year all-cause mortality, respectively. RESULTS In total, 13,204 patients (54% females, mean age 74 ± 11 years) were followed for a median of 3.5 years. Females were older (77 vs. 71 years), and had less frequent coronary artery disease (23% vs. 33%), dyslipidemia (44% vs. 50%), and diabetes (29% vs. 41%), as well as being less likely to have a history of smoking (10% vs. 15%) compared with males. Mortality differences were mostly attributable to the female subgroup who were revascularized above the knee (hazard ratio, HR 0.78, 95% CI: 0.64-0.95), while no statistically significant differences were observed in males. CONCLUSIONS This study found that females treated above the knee benefited from paclitaxel-coated devices, while no differences were found in males. Ongoing and future registries and trials should take sex disparities into account.

Abstract
Objectives: Peripheral arterial occlusive disease (PAOD) and periodontitis are common chronic diseases, which together affect almost 1 billion people worldwide. There is growing evidence suggesting a relationship between chronic inflammatory conditions such as periodontitis and PAOD. This study aims to determine an association between both entities using high quality research data and multiple phenotypes derived from an epidemiological cohort study. Design: This population-based cross-sectional cohort study included data from 3271 participants aged between 45 and 74 years enrolled in the Hamburg City Health Study (NCT03934957). Material & Methods: An ankle-brachial-index below 0.9, color-coded ultrasound of the lower extremity arteries, and survey data was used to identify participants with either asymptomatic or symptomatic PAOD. Periodontitis data was collected at six sites per tooth and included the probing depth, gingival recession, clinical attachment loss, and bleeding on probing index. Multivariate analyses using logistic regression models were adjusted for variables including age, sex, smoking, education, diabetes, and hypertension. Results: The baseline characteristics differed widely between participants neither affected by periodontitis nor PAOD vs. the group where both PAOD and severe periodontitis were identified. A higher rate of males, higher age, lower education level, smoking, diabetes, and cardiovascular disease was observed in the group affected by both diseases. After adjusting, presence of severe periodontitis (odds ratio 1.265; 97.5% CI 1.006–1.591; p = 0.045) was independently associated with PAOD. Conclusion: In this cross-sectional analysis of a prospective cohort study, an independent association between periodontitis and PAOD was revealed. The results of the current study emphasize a potential for preventive medicine in an extremely sensitive target population. Future studies should determine the underlying factors modifying the relationship between both diseases.

Abstract
AIMS Peripheral arterial disease (PAD) is associated with morbidity and mortality, comprising a significant percentage of amputations. As it affects the quality of life of patients with PAD, it is an important health issue. Therefore, the risk factors affecting the outcomes of limb salvage after revascularization should be well investigated. The aim of this review is to summarize risk factors of amputation-free survival (AFS) after interventions targeting patients with PAD to develop evidence-based intervention for improving patient outcomes. METHODS AND RESULTS A systematic review following PRISMA guidelines was conducted, and the protocol was registered on PROSPERO (CRD42020183076). PubMed, CINAHL, EMBASE, Cochrane Library, and Web of Science were searched for observational studies published between 2008 and 2019. Search terms included 'peripheral arterial disease', 'risk factors', and 'amputation-free survival'. The quality of the studies was evaluated using the Joanna Briggs Institute's Critical Appraisal Tools. Seventeen cohort studies were included in our study, and 16 risk factors were identified. Risk factors exemplifying a significant influence on decreased AFS were divided into three categories: sociodemographic (e.g. older age, male gender, African-American race, low body mass index, high nutritional risk, frailty), disease-related characteristics (e.g. severity of the disease, intervention site), and comorbidities (e.g. cardiovascular disease, kidney disease, diabetes mellitus, chronic obstructive pulmonary disease, dementia, wide pulse pressure). CONCLUSION We found that managing modifiable risk factors, as well as addressing high-risk populations, has the potential to improve outcomes of PAD interventions. More high-quality cohort studies are needed to confirm these findings.
