RESUMO

In this manual, the authors focused on the principal methods for diagnosis of peripheral artery disease in cardiological patients, from the interview and physical examination to functional tests and vascular visualization. Diagnostic and prognostic value of each method, its potentialities for reducing the risk of cardiovascular events (CVE), including myocardial infarction (MI), ischemic stroke (IS) or extremity amputation in critical ischemia, and overall mortality are discussed. The authors provided current information about a possibility of reducing the risk of CVE by intensifying the antithrombotic therapy according to results of the COMPASS study.

RESUMO

BACKGROUND: Patients with critical limb ischemia (CLI) involving the below-the-knee (BTK) arteries are at increased risk of limb loss. Despite improvement in endovascular modalities, it is still unclear whether an aggressive approach results in improved limb salvage. OBJECTIVES: To assess whether an aggressive approach to BTK arterial disease results in improved limb salvage. METHODS: A comparative study of two groups was conducted. Group 1 included patients treated between 2012 and 2014, primarily with transfemoral angioplasty of the tibial arteries. Group 2 included patients treated between 2015-2019 with a wide array of endovascular modalities (stents, multiple tibial artery and pedal angioplasty, retrograde access). Primary endpoint was freedom from amputation at 4 years. RESULTS: A total of 529 BTK interventions were performed. Mean age was 71 ± 10.6 years, 382 (79%) were male. Patients in group 1 were less likely to be taking clopidogrel (66% vs. 83%, P < 0.01) and statins (72 % vs. 87%, P < 0.01). Several therapeutic modalities were used more often in group 2 than in group 1, including pedal angioplasty (24 vs. 43 %, P = 0.01), tibial and pedal retrograde access (0 vs. 10%, P = 0.01), and tibial stenting (3% vs. 25%, P = 0.01). Revascularization of two or more tibial arteries was performed at a higher rate in group 2 (54% vs. 50%, P = 0.45). Estimated freedom from amputation at 40 months follow-up was higher in group 2 (53% vs. 63%, P = 0.05). CONCLUSIONS: An aggressive, multimodality approach in treating BTK arteries results in improved limb salvage.

RESUMO

Treatment of patients presenting with peripheral artery disease requires a comprehensive approach: correction of risk factors, drug therapy and, if necessary, an endovascular/hybrid/open intervention. Reconstructive operation may effectively improve a patient's quality of life in intermittent claudication, save the limb and life in case of severe ischaemia. Discussed in the article are advantages and disadvantages of various types of surgical interventions for peripheral artery disease, the concept PLAN (Patient risk, Limb severity, and ANatomic complexity) and the new Global Anatomic Staging System (GLASS). Good remote results may be ensured by adequate medicamentous therapy. Variations of antithrombotic therapy are versatile and debatable. Long-term dual antithrombotic or systemic anticoagulant therapy with administration of vitamin K antagonists are not indicated for peripheral artery disease. In this connection, the findings of the COMPASS and VOYAGER PAD studies are analysed. The VOYAGER PAD trial showed that in patients with peripheral artery disease who underwent revascularization of lower limbs, the addition of rivaroxaban at a dose of 2.5 mg twice daily to aspirin decreased the risk of lower-extremity unfavourable ischaemic events and major adverse cardiovascular events by 15%. The obtained findings open new possibilities of conservative therapy having a significant role in decreasing the risk for development of limb-threatening conditions.

RESUMO

Atherosclerosis is a systemic process. As the population ages, increasingly more patients who undergo coronary revascularization are complicated with peripheral artery disease (PAD). However, the large body of evidence in this area has not been limited to analysis from trial-based data from younger and relatively uncomplicated patients in Western countries. The impact of PAD on the outcomes can differ by patient characteristics, and integrated analysis of large-scale data is necessary. J-PCI is a universal (all-comer) nationwide registration system in Japan, regulated and audited by professional society that controls national board-certification system. For the present study, we extracted data of 894,014 percutaneous coronary intervention (PCI) cases performed between 2014 and 2017 (mean age 70.2 years [standard deviation 11.0]). In-hospital outcomes of PAD and Non-PAD patients were compared. PAD was defined as a previous history of stenosis of peripheral arteries or abdominal aortic aneurysm. Primary outcome was in-hospital mortality, and multivariable modeling was performed. A total of 66,891 patients (8.1%) had PAD. Crude in-hospital mortality rate was higher in this group (0.99% vs. 0.67% in Non-PAD group). PAD was associated with an increased risk of in-hospital mortality (odds ratio [OR] 1.383 [95% confidence interval 1.251-1.528]). However, the impact of PAD differed by kidney condition (OR 1.578 [1.370-1.821] for patients with chronic kidney disease [CKD] and OR 1.234 [1.076-1.416] without CKD: P for interaction 0.005), and by clinical presentation: PAD was not associated with an increased risk of in-hospital mortality in patients undergoing PCI for silent ischemia (OR 1.211 [0.8701-1.685]: P for interaction 0.002). Presence of PAD was independently associated with in-hospital mortality in patients receiving PCI. However, its impact varied substantially by the patient background or indication of the procedure.

RESUMO

BACKGROUND: In our clinic, a substantial number of patients present with transtibial residual limb pain of no specific somatic origin. Silicone liner induced tissue compression may reduce blood flow, possibly causing residual limb pain. Thus, as a first step we investigated if the liner itself has an effect on transcutaneous oxygen pressure (TcPO2). METHODS: Persons with unilateral transtibial amputation and residual limb pain of unknown origin were included. Medical history, including residual limb pain, was recorded, and the SF-36 administered. Resting TcPO2 levels were measured in the supine position and without a liner at 0, 10, 20 and 30 minutes using two sensors: one placed in the Transverse plane over the tip of the Tibia End (= TTE), the other placed in the Sagittal plane, distally over the Peroneal Compartment (= SPC). Measurements were repeated with specially prepared liners avoiding additional pressure due to sensor placement. Statistical analyses were performed using SPSS. RESULTS: Twenty persons (9 women, 11 men) with a mean age of 68.65 years (range 47-86 years) participated. The transtibial amputation occurred on average 43 months prior to study entry (range 3-119 months). With liner wear, both sensors measured TcPO2 levels that were significantly lower than those measured without a liner (TTE: p < 0.001; SPC: p = 0.002) after 10, 20 and 30 minutes. No significant differences were found between TcPO2 levels over time between the sensors. There were no significant associations between TcPO2 levels and pain, smoking status, age, duration of daily liner use, mobility level, and revision history. CONCLUSION: Resting TcPO2 levels decreased significantly while wearing a liner alone, without a prosthetic socket. Further studies are required to investigate the effect of liner wear on exercise TcPO2 levels.

RESUMO

INTRODUCTION: Intermittent claudication has a significant negative impact on the patients' quality of life. Revascularization procedures and noninvasive medical therapies can improve walking capacity. Cilostazol has IA recommendation for the treatment of intermittent claudication. AIM: The aim of this study was to evaluate the effect of a three-month cilostazol treatment on the health-related quality of life and on the lower-limb functional capacity in diabetic (DM) and non-diabetic patients (NDM) with intermittent claudication in the clinical practice. METHOD: The study was a multicenter, non-interventional trial; 812 patients with peripheral artery disease (Fontaine II stage, mean age: 67.17 years, male/female: 58.25/41.75%, 318 diabetics) were enrolled, who received cilostazol (50 or 100 mg twice a day) for 3 months. The quality of life was evaluated with the EQ-5D-3L questionnaire, the functional capacity with the WELCH questionnaire. Walking distances, ankle-brachial index were measured at baseline and after 3 months. RESULTS: Upon conclusion of the study, the EQ-5D index improved both in non-diabetic and diabetic patients (baseline: NDM -0.45 ± 0.22, DM -0.48 ± 0.23, 3rd month: -0,24 ± 0.18, -0,27 ± 0.19; respectively; p<0.0001) and there was a significant increase in the WELCH score as well (baseline: NDM 20 ± 14, DM 18 ± 14; 3rd month: 33 ± 19, 29 ± 16, respectively; p<0.0001). Both pain-free and maximal walking distance increased by 59.2% (median: 50.0%), 46.58 (median: 40.51%) in NDM and 42.85% (median: 43.33%), 41.61% (median: 34.68%) in DM patients, respectively (p<0.001). CONCLUSIONS: Three months of cilostazol treatment improved the quality of life and lower-limb functional capacity in diabetic and non-diabetic claudicant patients. The WELCH questionnaire is a useful tool in clinical practice for the evaluation of intermittent claudication treatment. Orv Hetil. 2020; 161(38): 1637-1645.

RESUMO

La diabetes mellitus tipo 2 (DM2) representa un problema de salud pública, debido a su alta incidencia y prevalencia en el mundo. Un método para evaluar el riesgo de desarrollar DM2 es la escala Latin American Finnish Diabetes Risk Score (LA FINDRISC). La DM2 es un factor de riesgo de enfermedad arterial periférica (EAP) la cual puede ser diagnosticada mediante el índice tobillo-brazo (ITB). Objetivo: evaluar la presencia y severidad de enfermedad arterial periférica mediante ITB y relacionarlo con el riesgo de desarrollar DM2 según LA FINDRISC. Métodos: estudio descriptivo, correlacional, de corte transversal. Se evaluaron 134 personas y se les midió glicemia capilar para descartar diabetes. Posteriormente, se realizó el LA FINDRISC y el ITB. Resultados: El puntaje LA FINDRISC y la glicemia alteradas en ayunas aumentaron proporcionalmente (R2=0,5). Esta relación no se observó entre LA FINDRISC y el ITB arrojado por la población general. Sin embargo, al seleccionar los pacientes con vasos no comprimibles aparece una correlación positiva (R2=0,36) entre los dos instrumentos diagnósticos. Conclusión: LA FINDRISC y el ITB son instrumentos de diagnósticos no invasivo, sencillos y válidos para detectar riesgo de desarrollar DM2, y detectar presencia y severidad de enfermedad arterial periférica, respectivamente(AU)


Type 2 diabetes mellitus (DM2) represents a public health problem, due to its high incidence and prevalence in the world. One method to assess the risk of developing DM2 is the Latin American Finnish Diabetes Risk Score (LA FINDRISC) scale. DM2 is a risk factor for peripheral arterial disease (PAD) which can be diagnosed using the ankle-brachial index (ABI). Objective: to evaluate the presence and severity of peripheral arterial disease using ABI and to relate it to the risk of developing DM2 according to LA FINDRISC. Methods: descriptive, correlational, cross-sectional study. 134 people were evaluated, and capillary glycemia was measured to rule out diabetes. Subsequently, the LA FINDRISC and the ITB were held. Results: The LA FINDRISC score and impaired fasting blood glucose increased proportionally (R2 = 0.5). This relationship was not observed between LA FINDRISC and the ITB showed by the general population. However, when selecting patients with non-compressible vessels, a positive correlation (R2 = 0.36) appears between the two diagnostic instruments. Conclusion: FINDRISC and ITB are simple and valid non-invasive diagnostic instruments to detect the risk of developing DM2, and detect the presence and severity of peripheral arterial disease, respectively(AU)

RESUMO

We sought to study the feasibility of axillary artery as alternative access for mechanical circulatory support (MCS) in cardiogenic shock and high-risk percutaneous coronary intervention (HR-PCI) patients with severe occlusive peripheral artery disease (PAD). In patients with severe PAD, the iliofemoral artery may be so diseased preventing deployment of MCS, precluding the use of lifesaving therapy. In such circumstances, the axillary artery may be a viable access site. Records of all patients presenting with cardiogenic shock or HR-PCI requiring MCS through axillary artery access at our institution from January 2016 to September 2018 were examined. Demographics, clinical, procedural, and outcomes data were collected on all patients. A total of 48 patients presented with cardiogenic shock (60%) or HR-PCI (40%) requiring MCS via axillary artery due to prohibitive PAD (mean age 66 ± 11 years). Admission diagnoses were non-ST segment elevation myocardial infarction (38%), unstable angina (23%), ST segment elevation myocardial infarction (19%), and cardiac arrest (21%). Time from axillary access to activation of Impella was 11.9 ± 4 minutes. Four patients required concomitant Impella RP for right ventricular support due to biventricular cardiogenic shock. Twenty-two patients died before Impella was explanted due to multiorgan failure, stroke, and infection. None of the patients who died had vascular complications related to axillary access. Axillary artery appears to be a viable alternative access for large bore devices in patients with prohibitive PAD. As experience of the field with this approach grows, it may be the default access for deployment of large bore sheaths in the future.

RESUMO

Despite witnessing an upsurge in heart valve diseases (HVDs), the correlation between HVDs and atherosclerotic peripheral arterial obstructive disease (PAOD) remains unclear. This study aims to investigate the prevalence and predictors of PAOD in HVDs.In this study, a total of 245 consecutive patients were examined: 153 with severe aortic valve stenosis (AS), 66 with severe primary mitral valve regurgitation (MR), and 26 with severe pure native aortic valve regurgitation (AR). All patients underwent ultrasound scan of the carotid artery to ascertain the presence of internal carotid artery stenosis (ICAS). ICAS was defined as a peak systolic velocity ≥ 125 cm/second and/or ≥ 50% reduction in diameter. In addition, we measured the ankle-brachial index in each leg using a volume plethysmograph. A result of ≤ 0.9 was considered lower extremity artery disease (LEAD).The presence of ICAS was statistically more frequent in patients with severe AS than in patients with severe MR and AR (11.1% versus 1.5% versus 3.8%; P = 0.038). LEAD was present in patients with severe AS (17.6%) and MR (10.6%) but not in patients with severe AR (P = 0.037). The multivariate analysis revealed that the presence of severe AS (OR, 5.6 [1.3-24.9]; P = 0.023) was an independent predictor for ICAS, while history of coronary artery disease (OR, 4.8 [2.2-10.5]; P < 0.001) was an independent predictor for LEAD.The prevalence of PAOD varies depending on each valvular disease. Individual screening should be considered on the basis of atherosclerotic risk factors, especially for patients with severe AS.

RESUMO

BACKGROUND: Although gender-related disparities in cardiovascular surgery have been investigated extensively in the past decades, knowledge about the impact of gender on outcomes after surgery for acute aortic dissection type A (AADA) is sparse. This study investigated the impact of gender on early morbidity and mortality and follow-up outcome in patients after surgery for AADA and to analyze gender-related risk factors for 30-day mortality. METHODS: This retrospective study included 368 consecutive patients (male 65.8% vs. female 34.2%) undergoing surgery for AADA between 2001 and 2016 at our department. Survival was estimated by Kaplan-Meier curves. Risk factors for 30-day mortality were assessed by multivariable logistic regression and interaction analysis. RESULTS: Women were older (70.7 years vs. 60.6 years; p <  0.001) and showed a higher logistic EuroSCORE I (31.0% vs. 19.7%, p <  0.001). In the male group, a higher portion of smokers (27.6% vs. 16.0%, p = 0.015) and intraoperatively, more complex procedures and longer cardiopulmonary bypass (CPB) (171 min vs. 149 min, p = 0.001) and cross-clamping times (94 min vs. 85 min, p = 0.018) occurred. 30-day mortality was 19.0% in the female and 16.5% in the male group (p = 0.545). Predictive for 30-day mortality in both genders was intraoperative blood transfusion, while in the female group chronic obstructive pulmonary disease (COPD), peripheral arterial disease and preoperative intubation were predictive. Preoperative cardiopulmonary resuscitation and duration of CPB time were predictors only in males. Averaged follow-up time was 5.2 years and survival did not differ between genders, even if it was stratified by age over 70 years. CONCLUSIONS: This analysis demonstrated a similar and satisfactory survival in both genders after surgical treatment of AADA. Women and men differed significantly in age, unadjusted and adjusted risk factors and complexity of surgical treatment, but gender itself was no risk factor for mortality. These results suggest that the decision-making for surgical treatment should not depend on gender, but that accounting for sex-specific risk factors rather than common risk factors may help to improve the outcome in both genders.

RESUMO

Peripheral artery disease (PAD) stems from atherosclerosis of lower extremity arteries with resultant arterial narrowing or occlusion. The most severe form of PAD is termed chronic limb-threatening ischemia and carries a significant risk of limb loss and cardiovascular mortality. Diabetes mellitus is known to increase the incidence of PAD, accelerate disease progression, and increase disease severity. Patients with concomitant diabetes mellitus and PAD are at high risk for major complications, such as amputation. Despite a decrease in the overall number of amputations performed annually in the United States, amputation rates among those with both diabetes mellitus and PAD have remained stable or even increased in high-risk subgroups. Within this cohort, there is significant regional, racial/ethnic, and socioeconomic variation in amputation risk. Specifically, residents of rural areas, African-American and Native American patients, and those of low socioeconomic status carry the highest risk of amputation. The burden of amputation is severe, with 5-year mortality rates exceeding those of many malignancies. Furthermore, caring for patients with PAD and diabetes mellitus imposes a significant cost to the healthcare system-estimated to range from $84 billion to $380 billion annually. Efforts to improve the quality of care for those with PAD and diabetes mellitus must focus on the subgroups at high risk for amputation and the disparities they face in the receipt of both preventive and interventional cardiovascular care. Better understanding of these social, economic, and structural barriers will prove to be crucial for cardiovascular physicians striving to better care for patients facing this challenging combination of chronic diseases.

RESUMO

Importance: Identifying modifiable risk factors, such as stress, that could inform the design of peripheral artery disease (PAD) management strategies is critical for reducing the risk of mortality. Few studies have examined the association of self-perceived stress with outcomes in patients with PAD. Objective: To examine the association of high levels of self-perceived stress with mortality in patients with PAD. Design, Setting, and Participants: This cohort study analyzed data from the registry of the Patient-Centered Outcomes Related to Treatment Practices in Peripheral Arterial Disease: Investigating Trajectories (PORTRAIT) study, a multicenter study that enrolled patients with new or worsening symptoms of PAD who presented to 16 subspecialty clinics across the US, the Netherlands, and Australia from June 2, 2011, to December 3, 2015. However, the present study included only patients in the US sites because assessments of mortality for patients in the Netherlands and Australia were not available. Data analysis was conducted from July 2019 to March 2020. Exposure: Self-perceived stress was quantified using the 4-item Perceived Stress Scale (PSS-4), with a score range of 0 to 16. A score of 6 or higher indicated high stress in this cohort. Missing scores were imputed using multiple imputation by chained equations with predictive mean matching. Stress was assessed at baseline and at 3-, 6-, and 12-month follow-up. Patients who reported high levels of stress at 2 or more follow-up assessments were categorized as having chronic stress. Main Outcomes and Measures: All-cause mortality was the primary study outcome. Such data for the subsequent 4 years after the 12-month follow-up were obtained from the National Death Index. Results: The final cohort included 765 patients, with a mean (SD) age of 68.4 (9.7) years. Of these patients, 57.8% were men and 71.6% were white individuals. High stress levels were reported in 65% of patients at baseline and in 20% at the 12-month follow-up. In an adjusted Cox proportional hazards regression model accounting for demographics, comorbidities, disease severity, treatment type, and socioeconomic status, exposure to chronic stress during the 12 months of follow-up was independently associated with increased risk of all-cause mortality in the subsequent 4 years (hazard ratio, 2.12; 95% CI, 1.14-3.94; P = .02). Conclusions and Relevance: In thie cohort study of patients with PAD, higher stress levels in the year after diagnosis appeared to be associated with greater long-term mortality risk, even after adjustment for confounding factors. These findings suggest that, given that stress is a modifiable risk factor for which evidence-based management strategies exist, a holistic approach that includes assessment of chronic stress has the potential to improve survival in patients with PAD.

RESUMO

Presentamos un caso de reconstrucción de extremidad inferior combinando revascularización arterial y un colgajo libre en un paciente de 72 años con enfermedad arterial oclusiva y defecto de cobertura con exposición ósea, mediante vascularización poplítea-pedia con bypass de safena y cobertura con colgajo libre de músculo recto abdominal. Debido a la ausencia de vasos receptores adecuados utilizamos el bypass como fuente de irrigación arterial y un injerto venoso entre la vena epigástrica donante y la vena poplítea como drenaje del colgajo. En pacientes que requieren reconstrucción extensa de partes blandas con enfermedad arterial oclusiva concomitante, el tratamiento combinado con revascularización quirúrgica y cobertura con colgajo libre está asociado a una alta tasa de salvamento de la extremidad y excelentes resultados funcionales. El colgajo libre de recto abdominal provee una adecuada cobertura y relleno de defectos tridimensionales, además de presentar ventajas en cuanto al tiempo de disección y el tamaño del pedículo. En casos de vasos receptores inadecuados, es posible utilizar el bypass como fuente arterial y un injerto venoso de drenaje a un vaso proximal


We present a case of lower extremity reconstruction combining bypass revascularization and free flap for soft tissue coverage in a 72-year-old diabetic man with lower extremity arterial occlusive disease and wide soft tissue defect with bone exposure, who was treated with a popliteal-pedal vein saphenous bypass and a free rectus abdominis muscle flap. The bypass was used as the arterial inflow to the flap and an interposition saphenous vein graft to the popliteal vein as the outflow vessel, due the absence of appropriate local venous receptor vessels. In patients with concomitant occlusive arterial disease, combined treatment with surgical revascularization and free flap coverage is associated with a high rate of limb salvage and excellent functional outcomes. The free rectus abdominis flap provides adequate coverage and filling of the defect, as well as advantages in terms of dissection time and donor vessel diameter. In cases of inadequate recipient vessels, it is possible to use the bypass conduit as an arterial inflow and another venous graft for outflow to a proximal vessel

RESUMO

BACKGROUND: Patients with lower limb peripheral artery disease (PAD) are at high risk of cardiovascular mortality and morbidity along with limb loss. PAD is underdiagnosed in the community and presents a missed opportunity to prescribe evidence-based secondary prevention therapy. OBJECTIVE: The aim of this article is to summarise key updates in the management of patients with PAD, with particular reference to newly published guidelines. DISCUSSION: PAD continues to be a major contributor to the mortality and morbidity of patients with atherosclerosis in Australia. For patients with chronic limb-threatening ischaemia, revascularisation remains the mainstay of limb salvage, and expedited access to vascular surgery assessment is necessary. Both prescription of, and adherence to, evidence-based secondary prevention therapy is low. A greater emphasis on cardiovascular risk factor modification for all patients with PAD is required to improve long-term outcomes. General practitioners and vascular surgeons can work collaboratively to provide patient-centred, effective care to patients with PAD.

RESUMO

Objective: Liver fibrosis is an important predictor of mortality in nonalcoholic fatty liver disease (NAFLD). Peripheral artery disease (PAD) and liver fibrosis share many common metabolic dysfunctions. We aimed to explore the association between PAD and risk of fibrosis deterioration in NAFLD patients. Methods: The study recruited 1,610 NAFLD patients aged ≥ 40 years from a well-defined community at baseline in 2010 and followed up between August 2014 and May 2015. Fibrosis deterioration was defined as the NAFLD fibrosis score (NFS) status increased to a higher category at the follow-up visit. PAD was defined as an ankle-brachial index of < 0.90 or > 1.40. Results: During an average of 4.3 years' follow-up, 618 patients progressed to a higher NFS category. PAD was associated with 92% increased risk of fibrosis deterioration [multivariable-adjusted odds ratio ( OR): 1.92, 95% confidence interval ( CI): 1.24, 2.98]. When stratified by baseline NFS status, the OR for progression from low to intermediate or high NFS was 1.74 (95% CI: 1.02, 3.00), and progression from intermediate to high NFS was 2.24 (95% CI: 1.05, 4.80). There was a significant interaction between PAD and insulin resistance (IR) on fibrosis deterioration ( P for interaction = 0.03). As compared with non-PAD and non-IR, the coexistence of PAD and IR was associated with a 3.85-fold (95% CI: 2.06, 7.18) increased risk of fibrosis deterioration. Conclusion: PAD is associated with an increased risk of fibrosis deterioration in NAFLD patients, especially in those with IR. The coexistence of PAD and IR may impose an interactive effect on the risk of fibrosis deterioration.

RESUMO

OBJECTIVE: The aims of this study were firstly to assess the correlation between disease specific measures of quality of life (QOL) and physical performance and activity, and secondly to identify demographic, clinical, functional, and physical activity measures independently associated with QOL in people with intermittent claudication. METHODS: This was a cross sectional observational study of 198 people with intermittent claudication caused by peripheral artery disease who were recruited prospectively. QOL was assessed with the intermittent claudication questionnaire (ICQ) and the eight-theme peripheral artery disease quality of life questionnaire. Physical performance was assessed with the six minute walk test (6MWT) and short physical performance battery (SPPB), and an accelerometer was used to measure seven day step count. The associations between QOL scores and 6MWT distance, SPPB scores and seven day step count were examined using Spearman Rho's (ρ) correlation and multivariable linear regression. RESULTS: ICQ scores were significantly correlated with 6MWT distance (ρ = 0.472, p < .001), all four SPPB scores (balance ρ = 0.207, p = .003; gait speed ρ = 0.303, p < .001; chair stand ρ = 0.167, p = .018; total ρ = 0.265, p < .001), and seven day step count (ρ = 0.254, p < .001). PADQOL social relationships and interactions (ρ = 0.343, p < .001) and symptoms and limitations in physical functioning (ρ = 0.355, p < .001) themes were correlated with 6MWT distance. The 6MWT distance was independently positively associated with ICQ and both PADQOL theme scores (ICQ: B 0.069, p < .001; PADQOL social relationships and interactions: B 0.077, p < .001; PADQOL symptoms and limitations in physical functioning: B 0.069, p < .001). CONCLUSION: Longer 6MWT distance independently predicted better physical and social aspects of QOL in people with intermittent claudication supporting its value as an outcome measure.
