BACKGROUND Peripheral arterial disease(PAD)has become one of the leading causes of disability and death in diabetic patients.Restoring blood supply to the hindlimbs,especially by promoting arteriogenesis,is currently the most effective strategy,in which endothelial cells play an important role.Tongxinluo(TXL)has been widely used for the treatment of cardio-cerebrovascular diseases and extended for diabetes-related vascular disease.AIM To investigate the effect of TXL on diabetic PAD and its underlying mechanisms.METHODS An animal model of diabetic PAD was established by ligating the femoral artery of db/db mice.Laser Doppler imaging and micro-computed tomography(micro-CT)were performed to assess the recovery of blood flow and arteriogenesis.Endothelial cell function related to arteriogenesis and cellular pyroptosis was assessed using histopathology,Western blot analysis,enzyme-linked immunosorbent assay and real-time polymerase chain reaction assays.In vitro,human vascular endothelial cells(HUVECs)and human vascular smooth muscle cells(VSMCs)were pretreated with TXL for 4 h,followed by incubation in high glucose and hypoxia conditions to induce cell injury.Then,indicators of HUVEC pyroptosis and function,HUVECVSMC interactions and the migration of VSMCs were measured.RESULTS Laser Doppler imaging and micro-CT showed that TXL restored blood flow to the hindlimbs and enhanced arteriogenesis.TXL also inhibited endothelial cell pyroptosis via the reactive oxygen species/nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3/Caspase-1/GSDMD signaling pathway.In addition,TXL restored endothelial cell functions,including maintaining the balance of vasodilation,acting as a barrier to reduce inflammation,and enhancing endothelial-smooth muscle cell interactions through the Jagged-1/Notch-1/ephrin-B2 signaling pathway.Similar results were observed in vitro.CONCLUSION TXL has a pro-arteriogenic effect in the treatment of diabetic PAD,and the mechanism may be related to the inhibition of endothelial cell pyroptosis,restoration of endothelial cell function and promotion of endothelial cell-smooth muscle cell interactions. 展开更多

Peripheral artery disease(PAD)is a common condition characterized by atherosclerosis in the peripheral arteries,associated with concomitant coronary and cerebrovascular diseases.Proprotein convertase subtilisin/kexin type 9(PCSK9)inhibitors are a class of drugs that have shown potential in hypercholesterolemic patients.This review focuses on the efficacy,safety,and clinical outcomes of PCSK9 inhibitors in PAD based on the literature indexed by PubMed.Trials such as FOURIER and ODYSSEY demonstrate the efficacy of evolocumab and alirocumab in reducing cardiovascular events,offering a potential treatment option for PAD patients.Safety evaluations from trials show few adverse events,most of which are injection-site reactions,indicating the overall safety profile of PCSK9 inhibitors.Clinical outcomes show a reduction in cardiovascular events,ischemic strokes,and major adverse limb events.However,despite these positive findings,PCSK9 inhibitors are still underutilized in clinical practice,possibly due to a lack of awareness among care providers and cost concerns.Further research is needed to establish the long-term effects and cost-effectiveness of PCSK9 inhibitors in PAD patients. 展开更多

Antiplatelet therapy with aspirin or clopidogrel or both is the standard care for patients with proven coronary or peripheral arterial disease,especially those undergoing endovascular revascularization procedures. However,despite the administration of the antiplatelet regiments,some patients still experience recurrent cardiovascular ischemic events. So far,it is well documented by several studies that in vitro response of platelets may be extremely variable. Poor antiplatelet effect of clopidogrel or high on-treatment platelet reactivity(HTPR) is under investigation by numerous recent studies. This review article focuses on methods used for the ex vivo evaluation of HTPR,as well as on the possible underlying mechanisms and the clinical consequences of this entity. Alternative therapeutic options and future directions are also addressed. 展开更多

Peripheral arterial disease, manifested as intermittent claudication or critical ischaemia, or identified by an ankle/brachial index < 0.9, is present in at least one in every four patients with type 2 diabetes mellitus.Several reasons exist for peripheral arterial disease indiabetes. In addition to hyperglycaemia, smoking and hypertension, the dyslipidaemia that accompanies type2 diabetes and is characterised by increased triglyceride levels and reduced high-density lipoprotein cholesterol concentrations also seems to contribute to this association. Recent years have witnessed an increased interest in postprandial lipidaemia, as a result of various prospective studies showing that non-fasting triglycerides predict the onset of arteriosclerotic cardiovascular disease better than fasting measurements do. Additionally,the use of certain specific postprandial particle markers,such as apolipoprotein B-48, makes it easier and more simple to approach the postprandial phenomenon. Despite this, only a few studies have evaluated the role of postprandial triglycerides in the development of peripheral arterial disease and type 2 diabetes. The purpose of this review is to examine the epidemiology and risk factors of peripheral arterial disease in type 2 diabetes, focusing on the role of postprandial triglycerides and particles. 展开更多

Objective To investigate the prevalence of peripheral arterial disease (PAD) in China type 2 diabetic patients and to demonstrate the relationships between putative risk factors and PAD. Methods In total 1 397 type 2 diabetic patients aged 50 years and older were enrolled and determined ankle-brachial index (ABI) and brachial-ankle pulse wave velocity (baPWV) in 15 Class III Grade A hospitals in 7 major cities of China. Results Mean patient age was 63.7±8.2 years and mean duration of diabetes mellitus was 9.39±7.4 years. Two hundreds and seventy-two (19.47%) patients were diagnosed as PAD by ABI <0.9, 122 (18.37%) in male and 150 (20.46%) in female. PAD patients had a significantly longer duration of diabetes mellitus, higher hemoglobin Alc, and a significantly lower mean body mass index than non-PAD ones. Aging, smoking, and systolic blood pressure were found to be positively related with the prevalence of PAD. In terms of lipid profiles, no variable was found to relate with PAD. Notably, baPWV showed as the same significant guiding index for PAD, almost matched with ABI. Conclusions PAD is a common complication in China type 2 diabetic patients. Therefore, PAD screening and treatment should be emphasized for diabetic patients with high risk factors. 展开更多

Purpose: To assess the efficacy of color Doppler imaging for decision making in the treatment of patients with lower extremity peripheral arterial disease (PAD) compared to digital subtraction angiography (DSA). Materials and Methods: Color Doppler scan was done on patients suspected for lower limb PAD, a day prior to the DSA which was done by a vascular surgeon. Also, for the patients who were candidates for endovascular intervention based on the color Doppler arterial mapping results, endovascular interventions were performed at the same time if the DSA findings are correlated with the color Doppler map. The grading for evaluated segments was normal, insignificant stenosis (<50%), hemodynamically significant stenosis (≥50%) and occlusion. We yielded the diagnostic efficacy indices of Doppler for detecting arterial stenosis in each 18 different arterial segments below the renal arteries including, infrarenal aorta, common and external iliac, common femoral, superficial femoral (proximal, middle and distal segments), deep femoral, popliteal artery, tibioperoneal trunk, anterior and posterior tibial arteries (proximal, middle and distal segments) and peroneal artery (proximal and distal segments). Then, we yielded the kappa agreement between Doppler and DSA findings considering the grade of stenosis in 18 arterial segments separately. Results: Totally 115 lower extremities (2045 arterial segments) were evaluated in 90 patients [mean age: 60.8 ± 8.9 (range: 47 - 84 years old)] of which 68 (75.6%) were men. The sensitivity of color Doppler for all arterial segments was 90% or higher except for common iliac artery, distal segment of superficial femoral artery and proximal segments of anterior and posterior tibialis and peroneal arteries. However, the specificity was 89% or higher, in all arterial segments. Kappa agreement was 0.72 or higher in all segments (All P-Values 0.001). Conclusion: This study suggests that considering excellent capability of color Doppler sonography in the evaluation of lower extremity arterial disease, color Doppler arterial mapping is sufficient for decision making in the treatment of these patients and can reduce the rate of diagnostic angiography. 展开更多

Patients with peripheral arterial disease(PAD)and critical limb ischemia are at risk for limb amputation and require urgent management to restore blood flow.Patients with PAD often have several comorbidities,including chronic kidney disease,diabetes mellitus,and hypertension.Diagnostic and interventional angiography using iodinated contrast agents provides excellent image resolution but can be associated with contrast-induced nephropathy(CIN).The use of carbon dioxide(CO2)as a contrast agent reduces the volume of iodine contrast required for angiography and reduces the incidence of CIN.However,CO2 angiography has been underutilized due to concerns regarding safety and image quality.Modern CO2 delivery systems with advanced digital subtraction angiography techniques and hybrid angiography have improved imaging accuracy and reduced the incidence of CIN.Awareness of the need for optimal imaging conditions,contraindications,and potential complications have improved the safety of CO2 angiography.This review aims to highlight current technological advances in the delivery of CO2 in vascular angiography for patients with PAD and critical limb ischemia,which result in limb preservation while preventing kidney damage. 展开更多

Objectives To assess the clinical efficacy, safety, and feasibility of autologous transplantation of mobilized peripheral blood mononuclear cells (PBMNCs) for patients with peripheral arterial occlusive disease (PAOD) of the lower extremity. Methods A total of 152 patients with PAOD of the lower extremity were enrolled into this non-controlled observational study from November 2003 to March 2006. All patients received subcutaneous injections of recombinant human granulocyte colony-stimulating factor (G-CSF, 450- 600 μg/day) for 5 days in order to mobilize stem/progenitor cells; their PBMNCs were collected and transplanted by multiple intramuscular injections into ischemic limbs. Patients were followed up for at least 12 weeks. Results At 12 weeks, primary manifestations, including lower limb pain and coldness, were significantly improved in 137 (90.1%) of the patients; limb ulcers improved or healed in 46 (86.8%) of the 53 patients, while 25 of the 48 (47.9%) patients with limb gangrene remained steady or improved. Ankle-brachial index (ABI) improved in 33 (22%) of the cases, and TcPO2 increased in 45 (30%) of the cases. Angiography before treatment, and at 12 weeks after treatment, was performed in 10 of the patients and showed formation of new collateral vessels. No severe adverse effects or complications specifically related to cell transplantation were observed. Conclusion Autologous transplantation of G-CSF–mobilized PBMNCs might be a safe and effective treatment for lower limb ischemic disorder. 展开更多

Smoking should be stopped and hypertension, diabetes mellitus, dyslipidemia, and hypothyroidism be treated in elderly patients with peripheral arterial disease (PAD). Statins reduce the incidence of intermittent claudication and improve exercise duration until the onset of intermittent claudication in persons with PAD and hypercholesterolemia. Antiplatelet drugs such as aspirin or clopidogrel, especially clopidogrel, angiotensin-converting enzyme inhibitors, and statins should be given to all persons with PAD. Beta blockers should be given if coronary artery disease is present. Exercise rehabilitation programs and cilostazol lengthen exercise time until intermittent claudication develops. Chelation therapy should be avoided. 展开更多

Objective: Evaluation of peripheral arterial disease with 64-detector multi-slice CT angiography (MDCT- A) and comparison of the results with the results of digital subtraction angiography (DSA), a standard reference. Materials and Method: The written informed consent of the patients and ethics committee approval were obtained. The retrospective study group consisted of 28 patients with a diagnosis of peripheral arterial disease. Using 64-MDCT-A, the arterial tree of the lower extremity was evaluated for the presence of steno-occlusive lesions that might have led to luminal stenosis. The diagnostic reliability of 64-MDCT- A was calculated and compared with that of DSA. Findings: In the segment-based analysis, the sensitivity, specificity, and reliability rates of 64-MDCT angiography in determining significant stenoses were 97.7%, 97%, and 97.3%, respectively. The Kappa co-efficiency for compatibility between 64-MDCT-A and DSA methods in grading stenosis was calculated as 0.896 展开更多

Importance of?thrombendarterectomy (TEA) had declined with the advent of bypass techniques and availability of prosthetic grafts, in patients with Peripheral arterial occlusive disease (PAOD). Recently, there had been a significant shift towards lower limb revascularization using endoluminal techniques. However, previously available data evaluating the long leg bypass or combined endoluminal and bypass procedures have been too anatomically heterogeneous to be easily applied to patients with infrainguinal disease and tissue loss. Clinical decision making in Complex multilevel or diffuse peripheral arterial occlusive disease with multiple co-morbidities especially associated coronary arterial disease is challenging. We describe twelve patients of iliofemoral arterial occlusive disease with tibiopopliteal arterial occlusive disease along with multiple co-morbidities like coronary arterial disease and diabetes mellitus who showed marked improvement with minimal post-operative?morbidities after iliofemoral or ileopopliteal bypass grafting with endarterectomy of the tibiopopliteal segment and related review of the literature. 展开更多

Over the last forty years in the field of peripheral arterial disease, there has been a plethora of research into cell-based therapies for tissue repair, regeneration and angiogenesis, progressing from protein-based therapies to gene therapies to stem cell research. Initial pre-clinical research successes have given birth to a whole industry, aimed at translating these laboratory hopes into clinical successes. However, heretofore these expected clinical results have failed to materialize, in part due to the lack of attention to the ischaemic desert like tissue and systemically diseased patient into which the stem cells are being implanted. Unsatisfactory clinical outcomes on the treatment of Critical Limb Ischaemia (CLI) have forced researchers to direct their efforts to the less intimidating challenge of claudication and to lower their clinical outcome thresholds from superior to “non-inferior”. Major questions on safety and durability have also arisen. What needs to be objectively established is the impact on the net health outcome of these therapies. Infusion or injection for stem cell therapy is still considered experimental and investigational. In this review we examine the clinical evidence for angiogenic therapies, focusing specifically on stem cell trials, in an attempt to answer the question “Is stem cell therapy a failed experiment or will there be light at the end of the tunnel?” 展开更多

Purpose: To study the association between carotid intima media thickness (CIMT) and high sensitivity CRP (hs-CRP) level as markers for PAD in elderly patients with DM. Subjects: A case-control study on 90 participants aged 60 years and older divided into 60 cases (30 patients with DM alone and 30 patients with DM and comorbidities) and 30 healthy controls. All were assessed by measuring CIMT, ankle brachial index (AB), and markers for cardiovascular disease such as high-sensitivity CRP (hs-CRP), total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL), and low density lipoprotein (LDL). Results: hs-CRP levels showed statistically significant difference being highest among patients with DM and comorbidities and lowest among controls (P < 0.001). Also, symptoms of PAD were significantly higher among cases than controls. ABI was able to detect PAD in many asymptomatic patients. Color changes were present in only 43.30% (n = 26) of positive PAD cases while delayed wound healing, claudication pain, rest pain, cold extremities, and trophic changes were present in 23.30% (n = 14), 16.71% (n = 10), 16.71% (n = 10), 45.00% (n = 27), and 21.7% (n = 13). Using logistic regression analysis revealed that DM, CIMT, and hs-CRP were independent predictors for PAD (OR = 4.194, 7.236, 1.003;P value = 0.044, 0.25, 0.031) after adjustment of other coronary risk factors such as sex, smoking, hypertension, TC, and TG. Conclusion: Diabetic elderly have higher prevalence of asymptomatic PAD thannon-diabetics using solely ABI. DM, CIMT, and hs-CRP are independent predictors for the occurrence of PAD. Hs-CRP levels are highest among diabetics with comorbidities. 展开更多

Doppler ultrasound scan is a non-invasive, cheap and convenient tool and it complements angiography, Computed tomography angiography (CTA), magnetic resonance angiography (MRA) and catheter digital subtraction angiography (DSA) in screening, diagnosis, treatment and follow-up of peripheral vascular diseases. Symptoms of peripheral vascular diseases are becoming more common due to rise in incidence of diseases and risk factors (diabetes mellitus, dyslipidemias, smoking, sedentary lifestyle). Due to limited availability of highly specific tools such as CT angiography, magnetic resonance angiography (MRA) and DSA (digital subtraction angiography) in many developing countries, doppler ultrasound is gaining more importance. Early determination of peripheral arterial diseases is beneficial in prevention of complications as severity increases may cause intermittent claudication, pain, tissue loss, including ulceration and gangrene (as the diseases progresses) and early management of arteriosclerosis will be beneficial to prevent these complications. 展开更多

This paper proposes a Van der Pol (VDP) oscillator screening for peripheral arterial disease (PAD) in patients with diabetes mellitus. The long-term elevated blood sugar levels produce a high risk of peripheral neuropathy and peripheral vascular disease, especially in the foot of a diabetic. Early detection is important, in order to prevent foot problems for diabetic patients with PAD. Photoplethysmography (PPG) is a non-invasive method for the detection of blood volume changes in peripheral arteries. Because of changes in the resistance-compliance, the rise time and transit time for the PPG signals increase and change in their shape are highly correlated with PAD severity. In this study, the Burg autoregressive (AR) method is used to determine the characteristic frequencies of the right-and left-side PPG signals. For bilateral frequency spectra, the VDP oscillator uses asynchronous signals. This produces damped sinusoidal responses and the oscillation overshoot (OS) is an approximating function only of the damped factor. This index is used to estimate the degree of PAD, including normal the condition and diabetic patients with PAD. The results show that the proposed method is efficient and more accurate in the estimation of PAD. 展开更多

BACKGROUND: Ankle brachial index (ABI) is widely involved in researches and clinical application of peripheral vascular injury of patients with diabetes mellitus (DM); however, the application in cerebral infarction (CI) is rare. OBJECTIVE: To investigate the possible risk factor of cerebral infarction plus peripheral arterial disease (PAD), compare metabolic characteristics of patients who having CI plus PAD or only having CI, and understand the significance of ABI on screening and diagnosing CI plus PAD of lower limb. DESIGN: Contrast observation based on CI patients. SETTING: Department of Neurology, Nanxishan Hospital of Guangxi Zhuang Autonomous Region. PARTICIPANTS: A total of 124 CI patients were selected from Department of Neurology, Nanxishan Hospital of Guangxi Zhuang Autonomous Region from July 2005 to April 2006, including 72 males and 52 females aged from 45 to 88 years. All patients met the diagnostic criteria of cerebrovascular disease established by National Academic Conference of Cerebrovascular Diseases in 1995 and determined as cerebral infarction with MRI or CT examination. All patients provided informed consent. There were 46 cases (37.2%) with CI plus PAD and 78 cases (62.8%) only with CI. METHODS: Blood pressure of bilateral ankles and upper extremities was measured at plain clinostatism with DINAMAP blood pressure monitor (GE Company). The ratio between average systolic pressure of lateral ankle and average systolic pressure of both upper extremities was regarded as ABI. The normal ABI was equal to or more than 0.9. If ABI < 0.9 occurred at one side, patients were diagnosed as PAD. On the second morning after hospitalization, blood was collected to measure fasting blood glucose (FBG), 2-hour postprandial blood glucose (PBG2h), glycosylated hemoglobin (HbA1c), triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). Among them, blood glucose, lipid and other biochemical markers were measured with enzyme chemistry assay and HbA1c was measured with HbA1c meter based on high liquid phase. Measurement data and enumeration data were compared with t test and Chi-square test, and multiple factors were dealt with Logistic regression analysis and multivariate linear regression analysis. MAIN OUTCOME MEASURES: Results of correlation between ABI and metabolic markers with multivariate linear regression analysis; risk factors of CI plus PAD with Logistic regression analysis; comparisons of metabolic markers between PAD and non-PAD patients. RESULTS: All 124 patients with acute CI were involved in the final analysis. ① Comparisons of metabolic markers: Levels of serum LDL-C and uric acid (UA) were higher of PAD patients than those of non-PAD patients (t =2.051 9, 3.339 1, P < 0.05); however, there were no significant differences among other metabolic markers (P > 0.05). ② Results of multivariate linear regression analysis: PBG2h, LDL-C and UA were obvious correlation with ABI of posterior tibial artery of lower limb and dorsal pedis artery (partial regression coefficient = -0.231 to -1.010, P < 0.05). ③ Risk factors of CI plus PAD with Logistic regression analysis: Age, smoking history, sum of CI focus (≥3) and LDL-C were independent risk factor of CI plus PAD (OR =1.524-5.422, P < 0.05-0.01). CONCLUSION: ① Levels of serum LDL-C and UA of patients with CI plus PAD are high. ② ABI of lower limbs is correlation with PBG2h, LDL-C and UA. In addition, measuring ABI is beneficial for early diagnosing PAD of lower limbs of patients who have poorly controlled blood glucose, abnormal lipid and poor renal function. ③ Age, LDL-C and sum of CI focus (≥3) are independent risk factors of CI plus PAD. It is of significance for screening non-PAD patients to evaluate risk degrees and prognosis and select therapeutic methods based on ABI measurement. 展开更多

It is a surrogate marker of generalized atherosclerosis. In sub-Saharan Africa, PAD remains understudied in CKD. Ankle-brachial index (ABI) is a non-invasive and cost-effective tool to diagnose PAD. <strong>Objectives:</strong> Our aim was to determine the prevalence and associated risk factors for PAD in hemodialysis patients. <strong>Patients and Methods:</strong> We conducted a cross-sectional study from July 1 to December 31, 2012 in the department of Nephrology of the University Hospital Aristide le Dantec of Dakar. All consenting patients, aged above 18 years, on hemodialysis for at least 6 months were included. ABI measurements were performed using a handled pulse doppler. PAD was defined as an ABI of <0.9 or the history of surgical revascularization and/or amputation due to vascular disease. The patients were divided into two groups according to the presence or not of PAD. Standard blood tests and anthropometrical parameters were recorded. <strong>Results:</strong> A total of 53 patients with a mean age of 49.15 ± 15.18 were included. The sex ratio was 0.70. Hypertension (83.01%), low HDL-cholesterol (26.41%) and cigarette smoking (20.75%) were the main cardiovascular risk factors. Prevalence of PAD was 47.16%. Among patients with PAD, 52% had no suggestive symptoms. Lower pre-dialysis (p = 0.0384) and post-dialysis (p = 0.0447) diastolic blood pressure (BP) were significantly associated with PAD. The conventional risk factors (tobacco consumption, diabetes, alcohol consumption, dyslipidemia, hypertension, age), iPTH and CRP levels were not correlated with PAD. <strong>Conclusion:</strong> PAD is common among patients undergoing maintenance hemodialysis in Senegal. Early diagnosis and management of PAD should be routinely performed in CKD patients. 展开更多
