<h4>Background</h4>Cardiovascular complications represent the major cause of morbidity and mortality of type 2 diabetes mellitus (T2DM) patients. In particular, peripheral artery disease (PAD) represents a frequent T2DM vascular complication and a risk factor for the development of major adverse cardiovascular events (MACE). Among adipokines, omentin-1 serum levels are reduced in T2DM patients with PAD and are inversely related to disease severity.<h4>Objective</h4>To study the relationship betw ...[more]

Project description:Background The long-term effectiveness of atherectomy treatment for peripheral arterial disease is unknown. We studied 5-year clinical outcomes by endovascular treatment type among patients with peripheral arterial disease. Methods and Results We queried the Medicare-linked VQI (Vascular Quality Initiative) registry for endovascular interventions from 2010 to 2015. The exposure was treatment type: atherectomy (with or without percutaneous transluminal angioplasty [ PTA] ), stent (with or without PTA ), or PTA alone. The outcomes were major amputation, any amputation, and major adverse limb event (major amputation or any reintervention). We used the center-specific proportions of atherectomy procedures performed in the 12 months before a patient's procedure as the instruments to perform an instrumental-variable Cox model analysis. Among 16 838 eligible patients (median follow-up: 1.3-1.5 years), 11% underwent atherectomy, 40% received PTA alone, and 49% underwent stenting. Patients receiving atherectomy commonly underwent femoropopliteal artery treatment (atherectomy: 65%; PTA : 49%; stenting: 43%; P<0.001) and had worse disease severity (Trans-Atlantic Inter-Society Consensus score [TASC] B and greater; atherectomy: 77%; PTA : 68%; stenting: 67%; P<0.001). The 5-year rate of major adverse limb events was 38% in patients receiving atherectomy versus 33% for PTA and 32% for stenting (log rank P<0.001). Controlling for unmeasured confounding using instrumental-variable analysis, patients treated with atherectomy experienced outcomes similar to those of patients treated with PTA , except for a higher risk of any amputation (hazard ratio: 1.51; 95% CI , 1.08-2.13). However, compared with stenting, atherectomy patients had a higher risk of major amputation (hazard ratio: 3.66; 95% CI , 1.72-7.81), any amputation (hazard ratio: 2.73; 95% CI , 1.60-4.76), and major adverse limb event (hazard ratio: 1.61; 95% CI , 1.10-2.38). Conclusions Atherectomy is used to treat severe femoropopliteal and tibial peripheral arterial disease even though long-term adverse outcomes occur more frequently after this treatment modality.

Project description:To determine whether diabetes mellitus has an independent impact on major limb outcomes at 1 year after endovascular treatment of lower extremity peripheral artery disease (PAD).The study involved 1906 consecutive patients (mean age 66 years; 1469 men) enrolled in the observational Excellence in Peripheral Artery Disease (XLPAD) registry ( ClinicalTrials.gov identifier NCT01904851) between January 2005 and October 2015 after undergoing index endovascular procedures in 2426 limbs for arterial occlusive disease. Patient outcomes included 12-month target limb amputation (above ankle) and target limb revascularization as well as all-cause death. Kaplan-Meier analysis and adjusted Cox proportional hazard models were used for time-to-event analysis of outcomes for the entire study sample as well as for the critical limb ischemia (CLI) and claudication subgroups. Results of the Cox regression models are reported as the hazard ratio (HR) and 95% confidence interval (CI).Diabetics undergoing endovascular procedures had higher rates of comorbid conditions (p<0.001), CLI (p<0.001), heavily calcified lesions (p=0.002), multivessel disease (p=0.030), and fewer infrapopliteal runoff vessels (p<0.001). Regression analysis after adjusting for confounders revealed significantly higher target limb major amputation in diabetics compared with nondiabetics (HR 5.02, 95% CI 1.44 to 17.56, p=0.011). However, repeat revascularization rates were similar. When considering CLI and claudication subgroups, diabetes was associated with a nonsignificant increased risk of 12-month major amputation only for patients presenting with CLI (HR 3.48, 95% CI 0.97 to 12.51, p=0.056). Diabetes was also associated with an increased risk of 12-month all-cause mortality in the overall study sample (HR 4.64, 95% CI 2.01 to 10.70, p<0.001) and in the CLI subgroup (HR 14.15, 95% CI 3.16 to 63.32, p<0.001) but not in the claudication subgroup (HR 1.42, 95% CI 0.45 to 4.54, p=0.552).Diabetes increases the risk of major amputation and all-cause death at 12 months following endovascular revascularization in patients with symptomatic PAD. These risks are especially heightened in patients presenting with CLI.

Project description:BACKGROUND: For patients with peripheral arterial disease (PAD), depression is associated with worse patency and recurrent symptoms in the treated leg, but its association with death or cardiovascular events in other vascular beds is unknown. OBJECTIVE: To assess the association between depression and mortality or cardiovascular events outside the affected leg after PAD revascularization. DESIGN: Retrospective cohort study. SUBJECTS: Two hundred fifty-seven consecutive patients undergoing lower extremity revascularization for symptomatic PAD at a single institution between January 2000 and May 2005 were included in this study. By protocol, patients were previously screened for depression and diagnosed by the primary care provider. MEASUREMENTS: The outcomes evaluated included a composite of death or major adverse cardiovascular events (MACE; coronary heart disease, contralateral PAD, or cerebrovascular event) as well as major outcome categories of death, coronary heart disease, contralateral PAD, or cerebrovascular events. RESULTS: At revascularization, 35.0% patients had been diagnosed with depression. Those with depression were significantly younger and more likely to use tobacco. By life-table analysis, patients with depression had significantly increased risk for death/MACE, coronary heart disease, and contralateral PAD events, but not cerebrovascular events or death. By multivariate analysis, patients with depression were at significantly increased risk for death/MACE (hazard ratio [HR] = 2.05; p < .0001), contralateral PAD (HR = 2.20; p = .009), and coronary heart disease events (HR = 2.31; p = .005) but not cerebrovascular events or death. CONCLUSIONS: Depression is common among patients undergoing revascularization for symptomatic PAD. After intervention, patients with depression are at significantly increased risk for coronary heart disease events and progression of contralateral PAD. Prospective analysis is required to confirm these results.

Project description:IntroductionPatients with chronic kidney disease (CKD) have a high prevalence of peripheral artery disease. How best to manage lower extremity peripheral artery disease remains unclear in this patient population. We therefore sought to compare the outcomes after endovascular versus surgical lower extremity revascularization among patients with CKD.MethodsWe used data from Optum's de-identifed Clinformatics® Data Mart Database, a nationwide database of commercially insured persons in the United States to study patients with CKD who underwent lower extremity endovascular or surgical revascularization. We used inverse probability of treatment weighting to balance covariates. We employed proportional hazard regression to study the primary outcome of major adverse limb events (MALE), defined as a repeat revascularization or amputation. We also studied each of these events separately and death from any cause.ResultsIn our cohort, 60,057 patients underwent endovascular revascularization and 9,338 patients underwent surgical revascularization. Endovascular revascularization compared with surgical revascularization was associated with a higher adjusted hazard of MALE (hazard ratio (HR) 1.52; 95% confidence interval (CI) 1.46-1.59). Endovascular revascularization was also associated with a higher adjusted hazard of repeat revascularization (HR 1.65; 95% CI 1.57-1.72) but a lower adjusted risk of amputation (HR 0.71; CI 0.73-0.89). Patients undergoing endovascular revascularization also had a lower adjusted hazard for death from any cause (0.85; CI 0.82-0.88).ConclusionsIn this analysis of patients with CKD undergoing lower extremity revascularization, an endovascular approach was associated with a higher rate of repeated revascularization but a lower risk of subsequent amputation and death compared with surgical revascularization. Multiple factors must be considered when counseling patients with CKD, who have a high burden of comorbid conditions. Clinical trials should include more patients with kidney disease, who are often otherwise excluded from participation, to better understand the most effective treatment strategies for this vulnerable patient population.

Project description:BackgroundPeripheral artery disease (PAD) represents one of the most relevant vascular complications of type 2 diabetes mellitus (T2DM). Moreover, T2DM patients suffering from PAD have an increased risk of major adverse cardiovascular events (MACE) and major adverse limb events (MALE). Sortilin, a protein involved in apolipoproteins trafficking, is associated with lower limb PAD in T2DM patients.ObjectiveTo evaluate the relationship between baseline serum levels of sortilin, MACE and MALE occurrence after revascularization of T2DM patients with PAD and chronic limb-threatening ischemia (CLTI).Research design and methodsWe performed a prospective non-randomized study including 230 statin-free T2DM patients with PAD and CLTI. Sortilin levels were measured before the endovascular intervention and incident outcomes were assessed during a 12 month follow-up.ResultsSortilin levels were significantly increased in individuals with more aggressive PAD (2.25 ± 0.51 ng/mL vs 1.44 ± 0.47 ng/mL, p < 0.001). During follow-up, 83 MACE and 116 MALE occurred. In patients, who then developed MACE and MALE, sortilin was higher. In particular, 2.46 ± 0.53 ng/mL vs 1.55 ± 0.42 ng/mL, p < 0.001 for MACE and 2.10 ± 0.54 ng/mL vs 1.65 ± 0.65 ng/mL, p < 0.001 for MALE. After adjusting for traditional atherosclerosis risk factors, the association between sortilin and vascular outcomes remained significant in a multivariate analysis. In our receiver operating characteristics (ROC) curve analysis using sortilin levels the prediction of MACE incidence improved (area under the curve [AUC] = 0.94) and MALE (AUC = 0.72).ConclusionsThis study demonstrates that sortilin correlates with incidence of MACE and MALE after endovascular revascularization in a diabetic population with PAD and CLTI.

Project description:Background Limited data exist to describe factors that influence the use of different endovascular treatments for peripheral arterial disease. Therefore, we studied sex differences in the utilization of endovascular treatment modalities and their impact on arterial patency. Methods and Results We analyzed procedures from 2010 to 2016 in the Vascular Quality Initiative for arteries treated with percutaneous transluminal angioplasty (PTA) alone, stenting (with/without PTA), and atherectomy (with/without PTA). We explored sex differences in treatment modality by arterial segment (iliac, femoropopliteal, and tibial) with multivariable logistic regression. We used Kaplan-Meier survival analysis and multivariable Cox regression to study sex differences in arterial reintervention and occlusion. In this cohort, patients (n=58 247, mean age 68 years, 41% women,) had 106 073 arteries treated (median=2 arteries, interquartile range=1-3). Half (50%) of these arteries were treated with stents, 39% with PTA alone, and 11% with atherectomy. After risk adjustment, women were less likely to undergo stenting or atherectomy (versus PTA alone) in the femoropopliteal (stent risk ratio=0.78 [0.74-0.82]; atherectomy risk ratio=0.69 [0.58-0.82]) and tibial arteries (stent risk ratio=0.70 [0.55-0.89]; atherectomy risk ratio=0.87 [0.70-1.07]). In the iliac arteries there was no sex difference in stenting, and atherectomy was rarely used (0.2%). Women underwent reintervention in the femoropopliteal arteries (hazard ratio=1.28 [1.17-1.40]) or developed an occlusion in the iliac (hazard ratio=1.42 [1.12-1.81]) and femoropopliteal arteries (hazard ratio=1.19 [1.06-1.34]) more frequently than men. Conclusions Women were less likely to undergo stenting or atherectomy and had higher rates of occlusion and reintervention, especially in the femoropopliteal arteries. Evidence-based guidelines are needed to guide optimal use of endovascular treatments for men and women.

Project description:OBJECTIVE:Lower extremity bypass (LEB) has traditionally been the "gold standard" in the treatment of critical limb ischemia (CLI). Infrainguinal endovascular intervention (IEI) has become more commonly performed than LEB, but comparative outcomes are limited. We sought to compare rates of major adverse limb events (MALEs) and major adverse cardiovascular events (MACEs) after LEB and IEI in a propensity score-matched, national cohort of patients with CLI. METHODS:The National Surgical Quality Improvement Program (NSQIP) vascular targeted files (2011-2014) for LEB and IEI were merged. CLI patients were identified by ischemic rest pain or tissue loss. Patients were matched on a 1:1 basis for propensity to undergo LEB or IEI. Primary outcomes were 30-day MALEs and MACEs. Within the propensity-matched cohort, multivariate logistic regression was used to identify independent predictors of MALEs and MACEs. RESULTS:A total of 13,294 LEBs and IEIs were identified, with 8066 cases performed for CLI. Propensity matching identified 3848 cases (1924 per group). There were no differences in preoperative variables between the propensity-matched LEB and IEI groups (all P > .05). At 30 days, rates of MALEs were significantly lower in the LEB group (9.2% LEB vs IEI 12.2%; P = .003). On multivariate logistic regression, bypass with single-segment saphenous vein vs IEI (odds ratio [OR], 0.7; 95% confidence interval [CI], 0.54-0.92; P = .01), bypass with alternative conduit (prosthetic, spliced vein, or composite) vs IEI (OR, 0.7; 95% CI, 0.56-0.98; P = .04), antiplatelet therapy (OR, 0.8; 95% CI, 0.58-1.00; P = .049), and statin therapy (OR, 0.8; 95% CI, 0.62-0.99; P = .04) were protective against MALEs, whereas infrageniculate intervention (OR, 1.4; 95% CI, 1.09-1.72; P = .01) and a history of prior bypass of the same arterial segment (OR, 1.8; 95% CI, 1.41-2.41; P <. 0001) were predictive. Rates of 30-day MACEs were not significantly different (4.9% LEB vs 3.7% IEI; P = .07) between the groups. Independent predictors of MACEs included age (OR, 1.02; 95% CI, 1.01-1.04; P = .01), steroid use (OR, 1.8; 95% CI, 1.08-2.99; P = .03), congestive heart failure (OR, 1.7; 95% CI, 1.00-1.96; P = .02), beta blocker use (OR, 1.6; 95% CI, 1.09-1.43; P = .01), dialysis (OR, 2.3; 95% CI, 1.55-3.45; P < .0001), totally dependent functional status (OR, 3.1; 95% CI, 1.25-7.58; P = .02), and suboptimal conduit for LEB compared with IEI (OR, 1.6; 95% CI, 1.08-2.36; P = .02). CONCLUSIONS:Within this large, propensity-matched, national cohort, LEB predicted lower risk-adjusted 30-day MALE rate compared with IEI. Furthermore, there was no difference in 30-day MACE rate between the groups despite higher inherent risk with open surgical procedures. Therefore, this study supports the effectiveness and primacy of LEB for revascularization in CLI.

Project description:ObjectiveHistorically, open surgical bypass provided a durable repair among diabetic patients with chronic limb-threatening ischemia (CLTI). In the current endovascular era, however, the difference in long-term outcomes between first-time revascularization strategies among patients with insulin-dependent diabetes mellitus (IDDM) is poorly understood.MethodsWe reviewed the records of all patients with IDDM undergoing a first-time infrainguinal bypass graft (BPG) or percutaneous transluminal angioplasty with or without stenting (PTA/S) for CLTI at our institution from 2005 to 2014. We defined IDDM as use of chronic insulin administration at baseline to control blood glucose levels and recorded the most recent glycated hemoglobin value available within 3 months before the procedure and fasting blood glucose level on the day of the procedure. We compared rates of wound healing, restenosis, reintervention, major amputation, and mortality between BPG and PTA/S in our population using χ2, Kaplan-Meier, and Cox regression analyses. As a sensitivity analysis, we calculated propensity scores and employed inverse probability weighting to account for nonrandom assignment to BPG vs PTA/S.ResultsOf 2869 infrainguinal revascularizations from 2005 to 2014, 655 limbs (316 BPG, 339 PTA/S) in 580 patients fit our criteria and underwent a first-time revascularization for CLTI. Patients undergoing BPG, compared with PTA/S, were similar in age (69 vs 68 years; P = .55), had similar rates of tissue loss (87% vs 91%; P = .07) and dialysis dependence (26% vs 28%; P = .55), were less likely to be hypertensive (84% vs 92%; P < .001), and were more likely to be current smokers (21% vs 14%; P = .02). There were no differences between BPG and PTA/S patients in mean glycated hemoglobin levels (8.1% vs 8.0%; P = .51) or mean fasting blood glucose levels (158 vs 150 mg/dL; P = .18). Although total hospital length of stay was significantly longer among BPG patients (11 vs 8 days; P < .001), perioperative complications did not differ, including acute kidney injury (19% vs 23%; P = .24), hematoma (6.0% vs 3.8%; P = .20), acute myocardial infarction (1.3% vs 2.1%; P = .43), and mortality (3.8% vs 3.0%; P = .55). BPG-first patients had significantly lower unadjusted 6-month rates of incomplete wound healing (49% vs 57%) and 5-year rates of restenosis (53% vs 72%) and reintervention (47% vs 58%; all P < .05). After adjustment, multivariable analysis suggested PTA/S-first intervention to be significantly associated with higher risk of restenosis (hazard ratio, 1.9; 95% confidence interval, 1.3-2.7) and reintervention (1.9 [1.2-2.7]). These results remained robust after inverse probability weighting.ConclusionsAmong patients with IDDM and CLTI, a bypass-first strategy is associated with similar 30-day outcomes and lower restenosis and reintervention rates. These data suggest that a bypass-first approach may best serve appropriately selected, anatomically suitable patients with IDDM and pedal ischemia that requires revascularization.

Project description:ObjectiveOptimal patient selection for lower extremity revascularization remains a clinical challenge among the hemodialysis-dependent (HD). The purpose of this study was to examine contemporary real world open and endovascular outcomes of HD patients to better facilitate patient selection for intervention.MethodsA regional multicenter registry was queried between 2003 and 2013 for HD patients (N = 689) undergoing open surgical bypass (n = 295) or endovascular intervention (n = 394) for lower extremity revascularization. Patient demographics and comorbidities were recorded. The primary outcome was overall survival. Secondary outcomes included graft patency, freedom from major adverse limb events, and amputation-free survival (AFS). Multivariate analysis was performed to identify independent risk factors for death and amputation.ResultsAmong the 689 HD patients undergoing lower extremity revascularization, 66% were male, and 83% were white. Ninety percent of revascularizations were performed for critical limb ischemia and 8% for claudication. Overall survival at 1, 2, and 5 years survival remained low at 60%, 43%, and 21%, respectively. Overall 1- and 2-year AFS was 40% and 17%. Mortality accounted for the primary mode of failure for both open bypass (78%) and endovascular interventions (80%) at two years. Survival, AFS, and freedom from major adverse limb event outcomes did not differ significantly between revascularization techniques. At 2 years, endovascular patency was higher than open bypass (76% vs 26%; 95% confidence interval [CI], 0.28-0.71; P = .02). Multivariate analysis identified age ≥80 years (hazard ratio [HR], 1.9; 95% CI, 1.4-2.5; P < .01), indication of rest pain or tissue loss (HR, 1.8; 95% CI, 1.3-2.6; P < .01), preoperative wheelchair/bedridden status (HR, 1.5; 95% CI, 1.1-2.1; P < .01), coronary artery disease (HR, 1.5; 95% CI, 1.2-1.9; P < .01), and chronic obstructive pulmonary disease (HR, 1.4; 95% CI, 1.1-1.8; P = .01) as independent predictors of death. The presence of three or more risk factors resulted in predicted 1-year mortality of 64%.ConclusionsOverall survival and AFS among HD patients remains poor, irrespective of revascularization strategy. Mortality remains the primary driver for these findings and justifies a prudent approach to patient selection. Focus for improved results should emphasize predictors of survival to better identify those most likely to benefit from revascularization.

Project description:Preprocedural computed tomography angiography (CTA) assists in evaluating vascular morphology and disease distribution and in treatment planning for patients with lower extremity peripheral artery disease (PAD). The aim of the study was to determine the predictive value of radiographic findings on CTA and technical success of endovascular revascularization of occlusions in the superficial femoral artery-popliteal (SFA-pop) region.Medical records and available imaging studies were reviewed for patients undergoing endovascular intervention for PAD between January 2013 and December 2015 at a single academic institution. Radiologists reviewed preoperative CTA scans of patients with occlusions in the SFA-pop region. Radiographic criteria previously used to evaluate chronic occlusions in the coronary arteries were used. Technical success, defined as restoration of inline flow through the SFA-pop region with <30% stenosis at the end of the procedure, and intraoperative details were evaluated.From 2013 to 2015, there were 407 patients who underwent 540 endovascular procedures for PAD. Preprocedural CTA scans were performed in 217 patients (53.3%), and 84 occlusions in the SFA-pop region were diagnosed. Ten occlusions were excluded as no endovascular attempt to cross the lesion was made because of extensive disease or concomitant iliac intervention. Of the remaining 74 occlusions in the SFA-pop region, 59 were successfully treated (80%) and 15 were unsuccessfully crossed (20%). The indications for revascularization were claudication in 57% of patients and critical limb ischemia in the remaining patients. TransAtlantic Inter-Society Consensus A, B, and C occlusions were treated with 87% success, whereas D occlusions were treated with 68% success (P = .047). There were nine occlusions with 100% vessel calcification that was associated with technical failure (P = .014). Longer lengths of occlusion were also associated with technical failure (P = .042). Multiple occlusions (P = .55), negative remodeling (P = .69), vessel runoff (P = .56), and percentage of vessel calcification (P = .059) were not associated with failure. On multivariable analysis, 100% calcification remained the only significant predictor of technical failure (odds ratio, 9.0; 95% confidence interval, 1.8-45.8; P = .008).Analysis of preoperative CTA shows 100% calcification as the best predictor of technical failure of endovascular revascularization of occlusions in the SFA-pop region. Further studies are needed to determine the cost-effectiveness of obtaining preoperative CTA for lower extremity PAD.
