Aim: A better knowledge of the biological consequences in the blood of these exercise-induced ischemic events in lower extremity artery disease (LEAD) may improve the prospects of disease management. We explored the preminus postexercise metabolomic difference in 39 patients with LEAD referred for a treadmill oximetry test [transcutaneous oximetry (TcPO2)].Methods: Ischemia was estimated through the sum of decrease from rest of oxygen pressure (DROPs) (limb TcPO2 changes minus chest TcPO2 changes) at buttocks, thighs, and calves regions. Targeted metabolomic analyses measuring 188 metabolites were performed on a few microliters blood samples taken at the earlobe at rest and 3 min after exercise.Results: Maximum walking distance (MWD) was 290 m (120–652 m) and ankle brachial index (ABI) was 0.67 ± 0.17. Supervised paired partial least squares discriminant analysis based on 23,345 models showed good predictive performance for test sets with a median area under the receiver operating characteristic (AUROC) curve value of 0.99 and a p-value of 0.00049. The best discriminant metabolites contributing to the model included a subset of 71 (47%) of the 150 accurately measured metabolites in the plasma, comprising 3 acylcarnitines, 3 amino acids, 5 biogenic amines, 9 sphingomyelin, 7 lysophosphatidylcholines, and 44 phosphatidylcholines. In addition, 16 of these metabolites were found to correlate with one or more severity scores of the LEAD.Conclusion: Our results provide new insights into the biological changes that accompany exercise in LEAD and contribute to a better understanding of walking impairment pathophysiology in LEAD, highlighting new candidate biomarkers.

Peripheral arterial disease (PAD) is characterized by lower limb atherosclerosis impairing blood supply and causing walking-induced leg pain or claudication. Adherence to traditional exercise training programs is poor due to these symptoms despite exercise being a mainstay of conservative treatment. Heat therapy improves many cardiovascular health outcomes, so this study tested if this was a viable alternative cardiovascular therapy for PAD patients. Volunteers with PAD were randomized to 12 wk of heat ( n = 11; mean age 76 ± 8 yr, BMI 28.7 ± 3.5 kg/m2, 4 females) or exercise ( n = 11; 74 ± 10 yr, 28.5 ± 6.8 kg/m2, 3 females). Heat involved spa bathing at ∼39°C, 3–5 days/wk for ≤30 min, followed by ≤30 min of callisthenics. Exercise involved ≤90 min of supervised walking and gym-based exercise, 1–2 days/wk. Following the interventions, total walking distance during a 6-min walk test increased (from ∼350 m) by 41 m (95% CI: [13, 69], P = 0.006) regardless of group, and pain-free walking distance increased (from ∼170 m) by 43 m ([22, 63], P < 0.001). Systolic blood pressure was reduced more following heat (−7 mmHg, [−4, −10], P < 0.001) than following exercise (−3 mmHg, [0, −6], P = 0.078), and diastolic and mean arterial pressure decreased by 4 mmHg in both groups ( P = 0.002). There were no significant changes in blood volume, ankle-brachial index, or measures of vascular health. There were no differences in the improvement in functional or blood pressure outcomes between heat and exercise in individuals with PAD. NEW & NOTEWORTHY Heat therapy via hot-water immersion and supervised exercise both improved walking distance and resting blood pressure in peripheral arterial disease (PAD) patients over 12 wk. Adherence to heat therapy was excellent, and the heat intervention was well tolerated. The results of the current study indicate that heat therapy can improve functional ability and has potential as an effective cardiovascular conditioning tool for individuals with PAD.

The aim of study was to determine the sensitivity and specificity of ankle brachial index in diagnosis of peripheral arterial disease in diabetics with coronary artery disease at a teaching hospital in North India. Materials and methods: All diabetic patients admitted with coronary artery disease who undergo coronary angiography irrespective of their presentation (stable angina, unstable angina, NSTEMI, STEMI) were included in the study. Systolic blood pressures of both arms at the brachial arteries and both lower limbs at the dorsalis pedis arteries were taken with the help of sphygmomanometer and a hand held doppler probe and recorded in the proforma. The higher of the two systolic pressures recorded at the ankle was divided by the highest of the systolic pressures recorded in the arms to get the ankle brachial index. The results of ABI were compared with peripheral angiography.

Peripheral arterial disease (PAD) results in insufficient flow to lower extremities. Aerobic exercise provides health benefits for individuals with PAD, but basic science behind it is still debated. Twenty-one PAD patients aged about 70 years with female/male as 7/14 were recruited. Among them, 11 were randomized to have supervised cycling training (SCT) and 10 to receive general healthcare (GHC) as controls. SCT participants completed 36 sessions of SCT at the first ventilation threshold within 12 weeks and the controls received GHC for 12 weeks. Ankle-brachial index (ABI), 6-min walk test (6MWT), peak oxygen consumption (V˙O2peak), minute ventilation (V˙E), minute carbon dioxide production (V˙CO2), erythrocyte rheology, including the maximal elongation index (EImax) and shear stress at 50% of maximal elongation (SS1/2), and the Short Form-36 (SF-36) questionnaire for quality of life (QoL) were assessed before and 12 weeks after initial visit. SCT significantly decreased the SS1/2 as well as SS1/2 to EImax ratio (SS1/2/EImax) and increased the erythrocyte osmolality in the hypertonic region as well as the area under EI-osmolality curve. The supervised exercise-induced improvement of erythrocyte deformability could contribute to the increased peripheral tissue O2 delivery and was possibly related with increased V˙O2peak. The physiological benefit was associated with significantly increased ABI, 6-min walking distance, cardiorespiratory fitness, and SF-36 score. However, no significant changes in aerobic capacity and erythrocyte rheological properties were observed after 12-week of GHC. In conclusion, SCT improves aerobic capacity by enhancing erythrocyte membrane deformability and consequently promotes QoL in PAD patients.

Background: Given the global burden of peripheral arterial disease (PAD) and the associated morbidity, continuing investigation of potential biomarkers as therapeutic targets for preventing PAD is warranted. The association of P-selectin, an endothelial cell adhesion molecule, with the ankle brachial index (ABI) and PAD is not well established. Thus, we examined the association of circulating P-selectin with prevalent and incident PAD, the ABI, and change in the ABI. Methods: The Multi-Ethnic Study of Atherosclerosis (MESA) is a prospective population-based cohort including 6814 non-Hispanic white, African American, Hispanic and Chinese men and women aged 45-84 at baseline (2000-02). For this analysis, 5700 participants with both P-selectin at Exam 2 (2002-04) and the ABI at Exam 3 (2004-05) were available, with change in ABI from Exam 3 to Exam 5 (2010-12) available on 4276 participants. P-selectin was modeled per standard deviation (SD), while prevalent and incident PAD were defined as ABI ≤ 0.90 after excluding those with ABI>1.4. Linear regression was used for ABI, growth curve models for change in ABI, and logistic regression for prevalent and incident PAD. Results: In models adjusted for demographics, lifestyle factors, comorbidities, blood pressure, lipids, fasting glucose, c-reactive protein (CRP), interleukin-6 (IL-6), D-dimer, and fibrinogen, each SD (13 ng/mL) higher P-selectin was significantly associated with 0.007 lower ABI (95% CI ((-0.011, -0.004)), p<0.001), and an average change in the ABI of -0.006 ((-0.010, -0.003, p<0.001). P-selectin was also significantly associated with a 1.14-fold greater odds of prevalent PAD ((1.00, 1.28), p=0.04), and a 1.30-fold greater odds of incident PAD ((1.10, 1.55), p<0.001). There were no significant interactions of p-selectin by race/ethnicity or gender. Addition of P-selectin to models containing traditional PAD risk factors as well as CRP, IL-6, D-dimer and fibrinogen did not improve the c-statistic or net reclassification for incident PAD. Conclusions: P-selectin appears to be strongly associated with the development of PAD. However, further research is needed in population-based studies to confirm prospective associations of p-selectin with incident PAD and change in the ABI.

Abstract Introduction : Diabetes Mellitus (DM) is conceptualized as a public health problem with varying degrees of morbidity. The physical and functional alternatives for the treatment of circulatory complications of diabetes, such as intermittent claudication, are poorly explored. This indicates the need to search for ancillary techniques that can be used in the physical therapy treatment of diabetic patients. Objective : To investigate the effects of functional hyperemia on peripheral arterial disease in patients with diabetes. Materials and methods: This study was conducted with a group of five volunteers from the Diabetics Association of Parana (Associação Paranaense do Diabético , APAD ), who suffered from peripheral vascular disorders in the lower limbs. All subjects attended 10 sessions (twice weekly). Functional hyperemia was induced by programmed exercise therapy that consisted of walking on a treadmill. Results : There was a significant increase in mean activity time (F9,36 = 13.710; p < 0.001 ), mean walking distance (F9,36 = 27.689 ; p < 001), and mean speed (F9,36 = 15.638 ; p < .001). No statistically significant differences in the ankle-brachial index were noted. Conclusion : There was a significant increase in walking distance, time, and speed for diabetic subjects. Our findings indicate the importance of physical therapists in the supervised treatment of peripheral vascular disorders in diabetic patients.

GlycA, a composite biomarker of systemic inflammation, is associated with cardiovascular disease (CVD) and mortality, but its relationship with peripheral artery disease (PAD) is unknown. We assessed whether plasma GlycA is associated with ankle–brachial index (ABI), carotid plaque (CP), and incident clinical PAD among 6466 Multi-Ethnic Study of Atherosclerosis participants without CVD at baseline. GlycA, ABI, and CP were measured at baseline. Both ABI and CP were remeasured at 10 years. Incident clinical PAD was ascertained from hospital records. We used logistic, Cox, and linear mixed regression models adjusted for demographic and lifestyle factors. Mean (standard deviation, SD) was 62 (10) years for age and 381 (61) µmol/L for GlycA; 53% were women. GlycA was associated with both prevalent low ABI ≤0.8 (prevalence odds ratio [95% confidence interval, CI] per SD increment in GlycA, 1.65 [1.39-1.97]) and CP (1.19 [1.11-1.27]) at baseline. There were no significant associations of GlycA with incident low ABI, incident CP, or 10-year change in ABI or CP score. We identified 110 incident cases of PAD after 79 590 person-years. The hazard ratio (95% CI) of incident PAD per SD increment in GlycA was 1.38 (1.14-1.66). In conclusion, GlycA was associated with prevalent low ABI, prevalent CP, and incident PAD after a median of 14 years.

Peripheral artery disease is a common vascular disorder. In contrast to coronary and cerebral artery disease, peripheral arterial disease remains an underappreciated condition that despite being serious and extremely prevalent is rarely diagnosed and even less frequently treated. Early diagnosis of peripheral artery disease and individual assessment of risk factors are important in preventing further cardiovascular complications. The ankle-brachial index is a simple, reliable tool for diagnosing peripheral artery disease. Many studies underscore the importance of using the ankle-brachial index to identify persons with peripheral artery disease, since peripheral artery disease is frequently undiagnosed or asymptomatic. Measurement of the ankle-brachial index is simple enough to be performed in any doctor’s office, and it is one of the most reliable indices of peripheral artery disease.

Antiplatelet drugs represent one of the basic options for management of patients with different atherosclerotic diseases. Aspirin is the oldest and most often prescribed antiplatelet drug. The efficacy of aspirin depends on the clinical characteristics of the treated population and probably also on the type or location of atherosclerotic disease. It seems that it is most effective in coronary patients with clinically unstable disease, less effective in prevention of cerebrovascular incidents, and its efficacy is uncertain in peripheral artery disease (PAD) patients. One of the first meta-analyses (Antithrombotic Trialists’ Collaboration - ATC) indicated that antiplatelet drugs also significantly reduce cardiovascular events in patients with PAD. However, only one third of the PAD patients included were treated with aspirin, while the rest received other anti-platelet drugs. The latest ATC meta-analysis of randomized control trials of aspirin therapy involving patients with diabetes and PAD demonstrated no benefit of aspirin in reducing cardiovascular events. Also in patients with preclinical PAD (pathological ankle brachial index) aspirin did not result in a significant reduction of vascular events. The new anti-platelet drugs prasugrel, ticagrelor and picotamide seem to be more effective than aspirin in PAD patients, particularly in diabetic patients with PAD. In conclusion, antiplatelet drugs are effective in prevention of cardiovascular events in different atherosclerotic diseases, including PAD. However, recent studies indicated that in PAD patients aspirin is less effective than in coronary artery disease. New anti-platelet drugs showed marginal superiority over aspirin without definite advantages. Aspirin thus remains the first line of antiplatelet drug for secondary prevention of cardiovascular events in PAD patients and clopidogrel as its effective alternative. Further, new studies on PAD patients are necessary to better define the role of anti-platelet agents in these patients and one of the promising ways of access to anti-platelet treatment would be personalized anti-platelet therapy.

Higher levels of hepatocyte growth factor (HGF) have been associated with the presence of peripheral arterial disease (PAD), but prospective associations are unknown. We examined the association of circulating HGF levels with incident PAD. Between 2000 and 2002, HGF was measured in 6742 Multi-Ethnic Study of Atherosclerosis participants without PAD. Incident clinical PAD, adjudicated on the basis of a positive history for the presence of disease-related symptoms or treatment, was ascertained through 2015. Incident low ankle-brachial index (ABI), defined as an ABI < 0.9 and a decline of ≥ 0.15, was assessed among 5736 individuals who had an ABI > 0.9 at baseline and ≥1 follow-up ABI measurement 3 to 10 years later. There were 116 clinical PAD and 197 low ABI events that occurred over a median follow-up of 14 and 9 years, respectively. After adjustment for demographic and clinical variables, a standard deviation increment of HGF (303 ng/L) was associated with an increased risk of clinical PAD (hazard ratio: 1.21; 95% confidence interval [CI]: 1.05-1.39) but not a low ABI (rate ratio: 1.03; 95% CI: 0.85-1.25). In conclusion, higher HGF levels were modestly associated with an increased risk of developing clinical PAD.

Abstract Peripheral artery disease (PAD) is associated with increased rates of physical disability in older adults, yet few interventions exist to reduce this risk. Intermittent claudication, exertional calf symptoms that resolve within 10 minutes of rest, is the classic symptom for PAD, but many people with PAD are absent of these symptoms. Ankle brachial index (ABI) is a non-invasive measure that identifies the presence and severity of lower extremity arterial obstruction due to atherosclerosis. We studied whether abnormal ABI is associated with increased time spent in sedentary behavior in a large sample of community-dwelling older men and women (70-89 years) enrolled in the Lifestyle Interventions and Independence for Elders (LIFE) study. Older adults underwent an ABI test and then wore a tri-axial accelerometer on the hip for up to seven days. Total accumulated sedentary time and sedentary time spent in bout lengths of 10minutes or more, 30 minutes or more, and 60 minutes or more were calculated. ABI values, divided into PAD (&lt;.90, n=156) and non-PAD (0.90 - 1.40, n=960), were evaluated in covariate-adjusted regression models adjusting for age, body mass index, comorbidity presence, gender and smoking. Older adults with PAD had significantly higher total accumulated time spent in sedentary behavior than those without PAD (13.1 minutes per day, p&lt;0.02). No associations were found with longer bout lengths of sedentary time. These results suggest that older adults with PAD accumulate more time in shorter bouts of sedentary behavior. Future interventions may consider targeting short sedentary bout-lengths for reducing PAD symptoms.
