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.

Abstract
OBJECTIVE Chronic limb threatening ischaemia (CLTI) has a devastating prognosis with high rates of lower limb amputation (LLA) and deaths. This is an illustration of contemporary management and the long term fate of patients after ischaemic LLA, particularly with respect to sex, using real world data. METHODS This was a multisectoral cross sectional and longitudinal analysis of health claims data from the largest German health insurance database (AOK). Data of 39 796 propensity score matched patients hospitalised for ischaemic LLA between 2010 and 2018 were analysed for cardiovascular comorbidities, treatment, and for subsequent cardiovascular and limb events, with a distinct focus on sex. Matching was performed, to ensure that the rate of major amputations and the age distribution were equal in both groups (in both sexes). An observation period of two years before index and a follow up (FU) period until 2019 were included. RESULTS Before index amputation, 68% of patients had received any kind of peripheral revascularisation. The use of statins (37.0% vs. 42.6%) and antithrombotic substances (54.9% vs. 61.8%) was lower in women than in men (p < .001). During two year FU, cardiovascular and limb events occurred among women and men as follows: limb re-amputation (26.7% vs. 31.2%), myocardial infarction (10.9% vs. 14.5%), stroke (20.8% vs. 20.7%), and death from any cause (51.0% vs. 53.3%, p < .001 except for stroke). After adjustment for cardiovascular comorbidities and vascular procedures, female sex was associated with a higher probability of death (HR 1.04, 95% CI 1.04 - 1.04). CONCLUSION Patients undergoing ischaemic LLA still have a poor prognosis marked by high rates of recurrent cardiovascular and limb events resulting in a > 50% mortality rate within two years. The continuous lack of guideline recommended therapies, particularly in women, may be associated with the persisting poor outcome, necessitating urgent further investigation.

Abstract
Peripheral arterial disease (PAD) is a prevalent medical condition associated with high mortality and morbidity rates. Despite the high clinical burden, sex-based differences among PAD patients are not well defined yet, in contrast to other atherosclerotic diseases. This study aimed to describe sex-based differences in clinical characteristics and outcomes among hospitalized patients affected by PAD. This was a retrospective study evaluating all patients with a diagnosis of PAD admitted to the Emergency Department from 1 December 2013 to 31 December 2021. The primary endpoint of the study was the difference between male and female PAD patients in cumulative occurrence of Major Adverse Cardiovascular Events (MACEs) and Major Adverse Limb Events. A total of 1640 patients were enrolled. Among them, 1103 (67.3%) were males while females were significantly older (median age of 75 years vs. 71 years; p =< 0.001). Females underwent more angioplasty treatments for revascularization than men (29.8% vs. 25.6%; p = 0.04); males were treated with more amputations (19.9% vs. 15.3%; p = 0.012). A trend toward more MALEs and MACEs reported in the male group did not reach statistical significance (OR 1.27 [0.99-1.64]; p = 0.059) (OR 0.75 [0.50-1.11]; p = 0.153). However, despite lower extremity PAD severity seeming similar between the two sexes, among these patients males had a higher probability of undergoing lower limb amputations, of cardiovascular death and of myocardial infarction. Among hospitalized patients affected by PAD, even if there was not a sex-based significant difference in the incidence of MALEs and MACEs, adverse clinical outcomes were more common in males.

Abstract
BACKGROUND Endovascular peripheral vascular intervention (PVI) has become the primary revascularization technique used for peripheral artery disease (PAD). Yet, there is limited understanding of long-term outcomes of PVI among women versus men. In this study, our objective was to investigate sex differences in the long-term outcomes of patients undergoing PVI. METHODS We performed a cohort study of patients undergoing PVI for PAD from January 1, 2010 to September 30, 2015 using data in the Vascular Quality Initiative (VQI) registry. Patients were linked to fee-for-service Medicare claims to identify late outcomes including major amputation, reintervention, major adverse limb event (major amputation or reintervention [MALE]), and mortality. Sex differences in outcomes were evaluated using cumulative incidence curves, Gray's test, and mixed effects Cox proportional hazards regression accounting for patient and lesion characteristics using inverse probability weighted estimates. RESULTS In this cohort of 15,437 patients, 44% (n = 6731) were women. Women were less likely to present with claudication than men (45% vs. 49%, p < 0.001, absolute standardized difference, d = 0.08) or be able to ambulate independently (ambulatory: 70% vs. 76%, p < 0.001, d = 0.14). There were no major sex differences in lesion characteristics, except for an increased frequency of tibial artery treatment in men (23% vs. 18% in women, p < 0.001, d = 0.12). Among patients with claudication, women had a higher risk-adjusted rate of major amputation (hazard ratio [HR] = 1.72, 95% confidence interval [CI]: 1.18-2.49), but a lower risk of mortality (HR = 0.86, 95% CI: 0.75-0.99). There were no sex differences in reintervention or MALE for patients with claudication. However, among patients with chronic limb-threatening ischemia, women had a lower risk-adjusted hazard of major amputation (HR = 0.79, 95% CI: 0.67-0.93), MALE (HR = 0.86, 95% CI: 0.78-0.96), and mortality (HR = 0.86, 95% CI: 0.79-0.94). CONCLUSION There is significant heterogeneity in PVI outcomes among men and women, especially after stratifying by symptom severity. A lower overall mortality in women with claudication was accompanied by a higher risk of major amputation. Men with chronic limb-threatening ischemia had a higher risk of major amputation, MALE, and mortality. Developing sex-specific approaches to PVI that prioritizes limb outcomes in women can improve the quality of vascular care for men and women.

Abstract
AIM OF THE STUDY The aim of our study was to analyse sex-specific differences in diagnosis and treatment of patients with lower extremity artery disease (LEAD) at Rutherford stage (RF) 1-3, based on secondary data. Furthermore, we focussed on the influence of the biological sex on short- and long-term outcome. METHODS The GenderVasc project is carried out in cooperation with the AOK Research Institute (WIdO). As data basis, anonymized routine data from all insured patients of the AOK were used. All patients hospitalized due to a main diagnosis of LEAD at RF 1-3 were included and in addition to the multisectoral cross-sectional analysis, longitudinal analysis (follow-up of up to 10 years) of the health claims data was performed and evaluated. RESULTS Our secondary data analysis of 42,197 patients with intermittent claudication (IC, LEAD at RF 1-3) showed that male patients were more often hospitalized due to LEAD, while women were older at time-point of index hospitalisation (female: 72.6 vs. male: 66.4 years). Fewer vascular procedures (diagnostic angiography and revascularisation) were carried out in females. Moreover, the prescription of guideline-recommended medications (statins and antithrombotic therapy) was lower in women compared to men. Multivariable Cox regression showed, after adjusting for age, cardiovascular risk profile and performed vascular procedure, that female sex was protective with respect to overall survival and progression of LEAD (progress to chronic limb-threatening ischemia or ischemic amputation). CONCLUSION In Germany, female LEAD patients were older and less likely to receive guideline-recommended therapy, while female sex is protective in terms of overall survival and progression of LEAD. The extent to which increased age or the presence of other comorbidities influence the decision for or against a vascular procedure can only be assumed from a secondary data analysis. Furthermore, the prescription of drugs in multimorbid patients is challenging and the compliance of the patients with prescribed medication intake is not part of our analysis. Nevertheless, targeted analysis, as in the GenderVasc project, are urgently needed to identify and describe differences in the medical care between the sexes.

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.

Abstract
Atherosclerotic peripheral artery disease (PAD) is associated with functional limitations and an increased risk of poor cardiovascular outcomes. Although men are traditionally viewed at higher risk of PAD than women, the true prevalence and incidence is inconsistent among available reports. Some of this variability is due to differences in PAD-related symptoms among women as well as sex-based differences in diagnostic tests, such as the ankle-brachial index, and it is critical for future epidemiologic studies to account for these differences. Generally, women with PAD experience greater functional impairment and decline then men and are less likely to receive guideline-directed medical therapy. In some settings, women are also more likely to present at later stages of disease and more often undergo lower limb amputation than men. Animal data exploring the biological underpinnings of these sex differences are limited, but several mechanisms have been postulated, including differential plaque morphology, alterations in the immune response, and hormonal variation and protection. Epidemiologic data suggest a link between inflammation and PAD and also reveal sex differences in lipid profiles associated with risk of PAD. In this review, we discuss available data on sex differences in PAD with additional focus on potential biological explanations for these differences. We also emphasize important knowledge gaps in this area, including under-representation of women in PAD clinical trials, to help guide future investigations and eliminate sex disparities in PAD.

Abstract
Aims The prevalence of chronic limb-threatening ischaemia (CLTI) is increasing and available data often derive from cohorts with various selection criteria. In the present study, we included CLTI patients and studied sex-related differences in their risk profile, vascular procedures, and long-term outcome. Methods and results We analysed 199 953 unselected patients of the largest public health insurance in Germany (AOK: Local healthcare funds), hospitalized between 2010 and 2017 for a main diagnosis of CLTI. A baseline period of 2 years before index hospitalization to assess comorbidities and previous procedures, and a follow-up period until 2018 were included. Female CLTI patients were older (median 81.4 vs. 73.8 years in males; P < 0.001) and more often diagnosed with hypertension, atrial fibrillation, chronic heart failure, and chronic kidney disease. Male patients suffered more frequently from diabetes mellitus, dyslipidaemia, smoking, cerebrovascular disease, and chronic coronary syndrome (all P < 0.001). Within hospitalized CLTI patients, females represent the minority (43% vs. 57%; P < 0.001) and during index hospitalization, women underwent less frequently diagnostic angiographies (67 vs. 70%) and revascularization procedures (61 vs. 65%; both P < 0.001). Moreover, women received less frequently guideline-recommended drugs like statins (35 vs. 43%) and antithrombotic therapy (48 vs. 53%; both P < 0.001) at baseline. Interestingly, after including age and comorbidities in a Cox regression analysis, female sex was associated with increased overall-survival (OS) [hazard ratio (HR) 0.95; 95% confidence interval (CI) 0.94–0.96] and amputation-free survival (AFS) (HR 0.84; 95% CI 0.83–0.85; both P < 0.001). Conclusion Female patients with CLTI were older, underwent less often vascular procedures, and received less frequently guideline-recommended medication. Nevertheless, female sex was independently associated with better OS and AFS during follow-up.

Abstract
Background: Sex-related differences may influence the outcome of endovascular revascularization (EVR) in patients with lower extremity arterial disease (LEAD) even under optimized healthcare supply. Patients and methods: LEAD patients who underwent EVR at the Department of Cardiology I - Coronary and Peripheral Vascular Disease, Heart Failure, University Hospital Muenster, Germany between 2014 and 2016 were included into the retrospective study. Detailed information on risk factors and co-morbidities, medication, LEAD related measures, and interventional parameters were assessed. Outcome defined as technical success rate, complications, and mortality was analyzed up to 12 months follow-up. Results: In total, 165 female and 437 male LEAD patients were included. Women and men presented with comparable severity of LEAD in terms of critical limb threatening ischemia (46.2%), wound status (34.9%), and amputation rate (9.6%, all n.s.) at index. Intake of platelet inhibitors (65.8% female vs. 70.0% male), oral anticoagulants (21.3% vs. 25.4%), and statins (65.6% vs. 76.0%) was observed less frequently in female patients. Against the background of high technical success (85%), in-hospital death (0.8%), severe adverse cardiac (MCE; 1.7%), and limb events (MALE; 6.1%) occurred at low rates in either sex. Adjusted long-term mortality was not affected by patients' sex (female HR 0.755; p=0.312). Conclusions: Despite critical LEAD stages in every second patient, EVR was performed safe with high technical success rates in female and male patients. Long-term outcomes were observed at comparatively low rates in both sexes at the specialized vascular center. During aftercare, supply with statin therapy turned out improvable particularly in female LEAD patients.

Sex related differences in therapy and outcome of patients with intermittent claudication in a real-world cohort. Atherosclerosis 2021; 325:75-82. [PMID: 33901740 DOI: 10.1016/j.atherosclerosis.2021.03.019] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Revised: 02/19/2021] [Accepted: 03/18/2021] [Indexed: 12/25/2022]
Abstract
BACKGROUND AND AIMS The prevalence of lower extremity artery disease (LEAD) is increasing worldwide and sex-related differences are a current matter of debate. METHODS We analysed claims data on unselected patients with in-patient treatment for LEAD with intermittent claudication (IC; Rutherford grade 1-3) from 01.01.2014 to 31.12.2015. Data files included diagnostic and procedural information from two years before index, and a five-year follow-up. RESULTS Our analysis comprised 42,197 IC patients, thereof 28,520 (68%) male. Male patients were younger (median: 66.4 years vs. 72.6 years) but presented with higher frequency of cardiovascular risk factors such as diabetes (40% female vs. 46% male), atrial fibrillation (13% vs. 17%), chronic coronary syndrome (41% vs. 53%), chronic heart failure (23% vs. 27%), or chronic kidney disease (29% vs. 32%; all p < 0.001; age adjusted). Revascularisation applied in 80% of patients, thereof endovascular approach predominantly in female and surgery in male patients. Concomitant pharmacotherapy with statins (74% at 2 years) and platelet inhibitors (75% respectively) were long lasting below guideline recommendation, under-use being more pronounced in women. Two years after index, one-third of IC patients had subsequent revascularisation, one-quarter progressed to chronic limb threatening ischemia (CLTI), and 2% underwent amputation. Male sex was an independent risk factor for long-term mortality (female HR 0.75; 95%-CI 0.72-0.79; p < 0.001) and CLTI (female HR 0.89; 95%-CI 0.86-0.92; p < 0.001) during follow-up. CONCLUSIONS The majority of in-patient treated patients for IC are male, presenting with worse cardiovascular risk profiles. In view of a general under-supply with statins and platelet inhibitors, women received somewhat less often preventive medication. Despite low LEAD stages at index, serious prognosis was observed in the long term. Particularly male patients were at high risk for all-cause mortality and the combined endpoint CLTI and death.

A health insurance claims analysis on the effect of female sex on long-term outcomes after peripheral endovascular interventions for symptomatic peripheral arterial occlusive disease. J Vasc Surg 2021; 74:780-787.e7. [PMID: 33647437 DOI: 10.1016/j.jvs.2021.01.066] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Accepted: 01/14/2021] [Indexed: 12/13/2022]
Abstract
OBJECTIVE Several reports have addressed sex disparities in peripheral arterial occlusive disease (PAOD) treatment with inconclusive or even conflicting results. However, most previous studies have neither been sufficiently stratified nor used matching or weighting methods to address severe confounding. In the present study, we aimed to determine the disparities between sexes after percutaneous endovascular revascularization (ER) for symptomatic PAOD. METHODS Health insurance claims data from the second-largest insurance fund in Germany, BARMER, were used. A large cohort of patients who had undergone index percutaneous ER of symptomatic PAOD from January 1, 2010 to December 31, 2018 were included in the present study. The study cohort was stratified by the presence of intermittent claudication, ischemic rest pain, and wound healing disorders. Propensity score matching was used to adjust for confounding through differences in age, treated vessel region, comorbidities, and pharmacologic treatment. Sex-related differences regarding cardiovascular event-free survival, amputation-free survival, and overall survival within 5 years of surgery were determined using Kaplan-Meier time-to-event curves, log-rank test, and Cox regression analysis. RESULTS In the present study, 50,051 patients (47.2% women) were identified and used to compose a matched cohort of 35,232 patients. Among all strata, female patients exhibited lower mortality (hazard ratio [HR], 0.69-0.90), fewer amputations or death (HR, 0.70-0.89), and fewer cardiovascular events or death (HR, 0.78-0.91). The association between female sex and improved long-term outcomes was most pronounced for the patients with intermittent claudication. CONCLUSIONS In the present propensity score-matched analysis of health insurance claims, we observed superior cardiovascular event-free survival, amputation-free survival, and overall survival during 5 years of follow-up after percutaneous ER in women with symptomatic PAOD. Future studies should address sex disparities in the open surgical treatment of PAOD to illuminate whether the conflicting data from previous reports might have resulted from insufficient stratification of the studies.

J Vasc Surg 2020; 73:1456-1465.e7.

Abstract
OBJECTIVE Individual studies of peripheral artery disease (PAD) have indicated that gender discrepancies exist in the symptoms, functional status, and treatment usage. It remains uncertain whether these discrepancies result in different long-term outcomes. We examined the potential gender differences in mortality and major adverse cardiovascular events (MACE) in patients with symptomatic PAD. METHODS The PubMed and Embase databases were searched for studies from 2000 to January 2019. After a review of 13,582 citations, 14 articles were analyzed. The reported age-adjusted hazard ratios (HRs) for gender differences in mortality and MACE were included in the meta-analysis. The mortality outcomes were stratified according to the clinical presentation and study context. RESULTS Male gender was associated with a greater risk of all-cause mortality (HR, 1.13; 95% confidence interval [CI], 1.10-1.16; P < .001) and MACE (HR, 1.10; 95% CI, 1.06-1.14; P < .001). In a stratified analysis, male gender was associated with a higher mortality risk for patients presenting with either critical limb ischemia (HR, 1.08; 95% CI, 1.05-1.10; P < .001) or mixed clinical presentations (HR, 1.16; 95% CI, 1.11-1.21; P < .001) but not for those with intermittent claudication (HR, 1.13; 95% CI, 0.98-1.30; P = .09). Elevated mortality risk was evident after revascularization (HR, 1.11; 95% CI, 1.04-1.19; P = .003), hospitalization (HR, 1.15; 95% CI, 1.08-1.22; P < .001), and amputation (HR, 1.09; 95% CI, 1.08-1.10; P < .001), although not in outpatient clinics (HR, 1.13; 95% CI, 0.97-1.32; P = .13), in men compared with women. CONCLUSIONS Greater mortality and MACE rates in men with PAD occurred despite other accepted gender disparities. The mechanisms underlying these gender differences in the outcomes for PAD patients require further investigation.

Abstract
BACKGROUND Patients with peripheral artery disease (PAD) have a higher risk of major adverse cardiovascular events (MACE) compared with those without PAD. OBJECTIVES The aim of this post hoc analysis was to evaluate sex-specific differences in MACE and limb events in the EUCLID (Examining Use of Ticagrelor in PAD) trial. METHODS Cox proportional hazards models were used to compare time-to-event outcomes stratified by sex. Covariates were introduced after adjusted model selection. RESULTS EUCLID enrolled 13,885 patients with PAD (28% women [n = 3,888]). PAD severity and medical treatment were comparable between sexes, whereas prior lower extremity revascularization was reported less frequently in women (54.8% vs. 57.3%; p = 0.006). Women were older (mean ± SD age: 67.8 ± 8.9 vs. 66.1 ± 8.2 years; p < 0.001) and more likely to have diabetes mellitus (p = 0.004), hypertension, hyperlipidemia, and chronic kidney disease (all p < 0.001). Over a mean follow-up of 30 months, women had a lower risk of MACE (9.5% vs. 11.2%; adjusted hazard ratio: 0.77; 95% confidence interval: 0.68 to 0.88; p < 0.001) and all-cause-mortality (7.6% vs. 9.7%; adjusted hazard ratio: 0.61; 95% confidence interval: 0.53 to 0.71; p < 0.001). In contrast, risk for major adverse limb events (2.6% vs. 3.0%) and hospitalization for acute limb ischemia (1.6% vs. 1.7%) were not different by sex. CONCLUSIONS Although women with PAD are at lower risk for MACE and all-cause mortality, risk for limb events was similar between sexes over a mean follow-up of 30 months. Understanding sex-specific differences and dissociation between baseline cardiovascular risk and subsequent cardiovascular events requires further investigation.

Abstract
Summary: Background: Patients with chronic critical limb-threatening ischemia (CLTI) are at high risk of amputation and death. Despite the general recommendation for revascularization in CTLI in the guidelines, the underlying evidence for such a recommendation is limited. The aim of our study was to assess the outcome of patients with CLTI depending on the use of revascularization in a retrospective real-world cohort. Patients and methods: Administrative data of the largest German Health insurance (BARMER GEK) were provided for all patients that were hospitalized for the treatment of CLTI Rutherford category (RF) 5 and 6 between 2009 and 2011. Patients were followed-up until December 31st, 2012 for limb amputation and death in relation to whether patients did (Rx +) or did not have (Rx −) revascularization during index-hospitalization. Results: We identified 15,314 patients with CLTI at RF5 (n = 6,908 (45.1%)) and RF6 (n = 8,406 (54.9%)), thereof 7,651 (50.0%) underwent revascularization (Rx +) and 7,663 (50.0%) were treated conservatively (Rx −). During follow-up (mean 647 days; 95% CI 640–654 days) limb amputation (46.5% Rx− vs. 40.6% Rx+, P < 0.001) and overall mortality (48.2% Rx− vs. 42.6% Rx+, P < 0.001) were significantly lower in the subgroup Rx+. Conclusions: In a real-world setting, only half of CLTI were revascularized during the in-hospital treatment. Though, revascularization was associated with significantly better observed short- and long-term outcome. These data do not allow causal conclusion due to lack of data on the underlying reason for applied or withheld revascularization and therefore may involve a relevant selection bias.

Abstract
BACKGROUND Peripheral artery disease (PAD) is frequently co-prevalent with coronary artery disease (CAD) and diabetes (DM). The study aims to define the burden of CAD and/ or DM in PAD patients at moderate stages and further to evaluate its impact on therapy and outcome. METHODS Study is based on health insurance claims data of the BARMER reflecting an unselected "real-world" scenario. Retrospective analyses were based on 21 197 patients hospitalized for PAD Rutherford 1-3 between 1 January 2009 to 31 December 2011, including a 4-year follow-up (median 775 days). RESULTS In PAD patients, CAD is prevalent in 25.3% (n = 5355), DM in 23.5% (n = 4976), and both CAD and DM in 8.2% (n = 1741). Overall, in-hospital mortality was 0.4%, being increased if CAD was present (CAD alone: OR 1.849; 95%-CI 1.066-3.208; DM alone: OR 1.028; 95%-CI 0.520-2.033; CAD and DM: OR 3.115; 95%-CI 1.720-5.641). Both, CAD and DM increased long-term mortality (CAD alone: HR 1.234; 95%-CI 1.106-1.376; DM alone: HR 1.260; 95%-CI 1.125-1.412; CAD and DM: HR 1.76; 95%-CI 1.552-1.995). DM further increased long-term amputation risk (DM alone: HR 2.238; 95%-CI 1.849-2.710; DM and CAD: HR 2.199; 95%-CI 1.732-2.792), whereas CAD (alone) did not. CONCLUSIONS In a greater perspective, the data identify also mild to modest stage PAD patients at particular risk for adverse outcomes in presence of CAD and/or DM. CAD and DM both are related with a highly increased risk of long-term mortality even in intermittent claudication, and DM independently increased amputation risk.
