In this paper, an ultralow dose paclitaxel-coated balloon was developed. Benefiting from the unique design of the meglumine matrix and outer protective sheath, its therapeutic effect was comparable to those of commercial high-dose counterparts in the swine model.

Background Patients with peripheral arterial disease (PAD) have known to a high risk of cardiac mortality. However, the effectiveness of the routine evaluation of coronary arteries such as routine coronary angiography (CAG) in PAD patients receiving percutaneous transluminal angioplasty (PTA) is unclear. Methods A total of 765 consecutive PAD patients underwent successful PTA and 674 patients (88.1%) underwent routine CAG. Coronary artery disease (CAD) was defined as angiographic stenosis ≥70%. Patients were divided into three groups; 1) routine CAG and a presence of CAD (n = 413 patients), 2) routine CAG and no CAD group (n = 261 patients), and 3) no CAG group (n = 91 patients). To adjust for any potential confounders that could cause bias, multivariable Cox-proportional hazards regression and propensity score matching (PSM) analysis was performed. Clinical outcomes were evaluated by Kaplan-Meier curved analysis at 5-year follow-up. Results In this study, the 5-year survival rate of patients with PAD who underwent PTA was 88.5%. Survival rates were similar among the CAD group, the no CAD group, and the no CAG group, respectively (87.7% vs. 90.4% vs. 86.8% P = 0.241). After PSM analysis between the CAD group and the no CAD group, during the 5-year clinical follow-up, there were no differences in the incidence of death, myocardial infarction, strokes, peripheral revascularization, or target extremity surgeries between the two groups except for repeat PCI, which was higher in the CAD group than the non-CAD group (9.3% vs. 0.8%, P<0.001). Conclusion PAD patients with CAD were expected to have very poor long-term survival, but they are shown no different long-term prognosis such as mortality compared to PAD patients without CAD. These PAD patients with CAD had received PCI and/or optimal medication treatment after the CAG. Therefore a strategy of routine CAG and subsequent PCI, if required, appears to be a reasonable strategy for mortality risk reduction of PAD patients. Our results highlight the importance for evaluation for CAD in patients with PAD.

Background: Obtaining adequate lipid control (LDL-Cholesterol [LDL] <100 mg/dL) in patients with peripheral arterial disease (PAD) is a critical, guideline-directed secondary prevention target. Current compliance with this recommendation is unknown. Methods: A total of 616 patients had their LDL levels measured at 2 vascular specialty clinics in the Netherlands (March 2006-November 2011) during the evaluation of new PAD symptoms. A year following this evaluation, 417 (68%) patients had their LDL levels re-assessed. Information about patients’ demographic and clinical factors was systematically abstracted from medical records. Categories of patients were created based on the attainment of the recommended LDL target (<100 mg/dL [on target] vs. ≥100 mg/dL [off target]). Predictors of being off target at initial evaluation and at 1-year follow-up were identified through multivariable logistic regression analyses. Results: Of the total group, 57% (351/616) were off target at initial evaluation and 81% (496/616) were on lipid-lowering drugs after the initial evaluation at the PAD specialty clinic. One year later, only 25% (103/417) got on target, while 35% (147/417) patients remained off target, and an additional 10% (43/417) saw an increase in LDL to become off target. A total of 30% (124/417) remained on target. Patients with hypertension, diabetes, a history of myocardial infarction, and a lower ankle-brachial index were less likely to be off target at initial evaluation. Predictors of being off target at 1-year follow-up were male sex, and having a higher ankle-brachial index ( Table ). Conclusion: About half of patients with PAD seen at vascular specialty clinics had above-target LDL levels both upon entry and 1 year later. Patients with existing cardiovascular risk factors were much better controlled, as compared with patients without such risk factors. Males and those with higher ankle-brachial indices were less likely to be on target 1 year following management at the specialty clinic. Reasons for poorly regulated lipids need to be further explored, and appropriate quality-of-care improvement strategies will likely be needed to optimize secondary prevention.

Background: Peripheral arterial disease (PAD) is a costly source of morbidity and mortality among older persons in the United States. Dietary intake plays a role in the development of atherosclerotic cardiovascular disease; however, few studies have examined the relation of food intake or diet patterns with PAD. Objectives: We examined the relationship between habitual dietary intake at midlife and incident PAD over approximately 20 years of follow-up. Methods: Among 14,082 participants enrolled in the Atherosclerosis Risk in Communities (ARIC) study initially free of PAD, dietary intake was assessed at baseline in 1987-1989 using a Harvard food frequency questionnaire. Food groups were created and principal components analysis was used to develop “healthy” and “Western” dietary patterns; both were categorized into quintiles or quartiles. Incident PAD was defined by an ankle-brachial index (ABI) measure of < 0.90 at either of two subsequent exams (1993-1995, 1996-1998), or a hospital discharge diagnosis of PAD, leg amputation, or leg revascularization procedures through 2012. Cox proportional hazards models adjusted for relevant confounders assessed the relations of each food group or diet pattern with incident PAD. Results: During a mean follow up of 19.9 years, 1569 participants developed incident PAD. A total of 64.7% of cases had their incident event defined via ICD-9 codes, while 35.3% had incident PAD defined by ABI. In models adjusted for demographics, behaviors, and food groups, the hazard ratios for incident PAD increased across quintiles of meat consumption (Q2 vs. Q1 1.38 [95% CI 1.16, 1.64], Q3 vs. Q1 1.40 [1.18, 1.67], Q4 vs. Q1 1.47 [1.23, 1.77], Q5 vs. Q1 1.66 [1.36, 2.03], p for trend <0.001). Compared to those who drank no alcohol, those who had 1-6 drinks per week had a lower risk of incident PAD (HR=0.78 [95% CI 0.68, 0.89]). For coffee, there was a modest inverse association with incident PAD (Q5 vs. Q1 0.84 [0.75, 1.00], p for trend = 0.014). There was no association between other food groups or patterns and incident PAD. Conclusions: In this prospective population-based cohort study, greater meat consumption was associated with higher risk of incident PAD, while both moderate alcohol consumption and coffee consumption were associated with lower risk of incident PAD. Whether these associations are causal remains to be seen.

Introduction: PAD was asymptomatic in a large proportion of COPD patients and was associated with more severe lung disease than in COPD subjects without PAD. Materials and Methods: This was a Cross-sectional study conducted at Department of Physiology, Santosh Medical College diagnosed with COPD using Spirometry was recruited for the study with a Sample size of 130 patients. Results: The characteristics of the population for follow-up (n=130) are presented in table 1. The mean Mean±SD was 51.73±6.1 years. The prevalence of never smokers was 21.5%, former smokers were 51.5% and current smokers were 26.9%. In total, 41 out of 130 individuals (31.5%) had PAD based on an ABI of less than 0.6. A statistically significant association was found between COPD and newly diagnosed PAD during follow-up. The association between COPD and incident PAD was stronger (adjusted OR 1.91, 95% CI 1.14–3.21). Stratified analysis by smoking status revealed that the overall association between COPD and newly developed PAD was driven by the ever smoker group. Conclusion: Subjects with COPD have a higher risk of developing PAD. People with both COPD and PAD have a substantially increased risk of death. Consequently, early detection of PAD and preventive actions in people with COPD should receive more attention in clinical respiratory care.
