Oral nutritional supplements in older outpatients with heart failure: rationale and design of the ALIMENT-HF trial.

AIMS: The ALIMENT-HF trial aims to determine whether high-calorie and high-protein oral nutritional supplements (ONS) are safe and beneficial for older adult outpatients with heart failure (HF). METHODS AND RESULTS: This multicentre, single-arm, interventional pilot trial is designed to evaluate the tolerance, efficacy, and safety of ONS in older adult outpatients with chronic HF, malnutrition, and anorexia. In total, 80 outpatients with HF regardless of their left ventricular ejection fraction will be treated with ONS, including high-energy (900 kcal/day) and high protein (36 g/day) supplementation, at eight sites in Japan. Inclusion criteria are as follows: age, ≥65 years; outpatients receiving maximally tolerated guideline-directed medical therapy for HF and without change in their diuretic dosage during the last 3 months; outpatients at risk of malnutrition, defined as a Malnutrition Universal Screening Tool score ≥1 point, and anorexia, defined using a Simplified Nutritional Appetite Questionnaire for the Japanese Elderly (SNAQ-JE) score of ≤14 points. Nutritional intervention will continue for up to 120 days, with an observational period lasting for a further 60 days. The primary outcome is a change in body weight between baseline and day 120. CONCLUSIONS: The ALIMENT-HF trial will evaluate the tolerance, efficacy, and safety of high-calorie and high-protein-rich ONS in older outpatients with HF co-morbid with malnutrition and anorexia and will provide insightful information for future randomized controlled trials.

Lipoprotein Apheresis Alleviates Treatment-Resistant Peripheral Artery Disease Despite the Normal Range of Atherogenic Lipoproteins: The LETS-PAD Study.

AIM: Peripheral artery disease (PAD) severely impairs patient prognosis and quality of life (QOL). Although lipoprotein apheresis (LA) has been applied to patients with PAD and elevated serum atherogenic lipoproteins, we hypothesized that LA can be effective for treating PAD even in patients with controlled serum lipoproteins through pleiotropic anti-atherosclerotic effects beyond lipoprotein removal. This study aimed to evaluate the efficacy of LA in patients with treatment-resistant PAD and controlled serum lipoproteins focusing on QOL. METHODS: In a single-arm prospective study, 30 patients with refractory PAD who had controlled serum lipoproteins underwent sequential LA sessions using dextran sulfate adsorption columns, aiming to complete 10 sessions. The ankle-brachial pressure index (ABI) and vascular QOL (VascuQOL) score were evaluated as the primary outcomes. Secondary outcomes included reactive hyperemia index (RHI) and biological antioxidant potential (BAP) as an endothelial function test and serum antioxidative-capacity evaluation, respectively. RESULTS: ABI significantly increased after LA sessions (pre-treatment 0.60±0.09 vs. post-treatment 0.65±0.13, p=0.023). Total VascuQOL score (3.7±1.1 vs 4.6±1.1, p＜0.001) and RHI (1.70±0.74 vs 2.34±1.76, p=0.023) significantly improved after the LA sessions. BAP tended to increase after the LA sessions, and the change reached statistical significance 3 months after treatment. CONCLUSION: ABI and QOL improved after a series of LA sessions in conventional treatment-resistant PAD patients with controlled serum lipoprotein levels. Increased antioxidative capacity and ameliorated endothelial function were observed after the LA treatment.

Association between evolocumab use and slow progression of aortic valve stenosis.

No medications have been reported to inhibit the progression of aortic valve stenosis (AS). The present study aimed to investigate whether evolocumab use is related to the slow progression of AS evaluated by serial echocardiography. This was a retrospective observational study from 2017 to 2022 at Yokohama City University Medical Center. Patients aged ≥ 18 with moderate AS were included. Exclusion criteria were (1) mild AS; (2) severe AS defined by maximum aortic valve (AV) velocity ≥ 4.0 m/s; and/or (3) no data of annual follow-up echocardiography. The primary endpoint was the association between evolocumab use and annual changes in the maximum AV-velocity or peak AV-pressure gradient (PG). A total of 57 patients were enrolled: 9 patients treated with evolocumab (evolocumab group), and the other 48 patients assigned to a control group. During a median follow-up of 33 months, the cumulative incidence of AS events (a composite of all-cause death, AV intervention, or unplanned hospitalization for heart failure) was 11% in the evolocumab group and 58% in the control group (P = 0.012). Annual change of maximum AV-velocity or peak AV-PG from the baseline to the next year was 0.02 (- 0.18 to 0.22) m/s per year or 0.60 (- 4.20 to 6.44) mmHg per year in the evolocumab group, whereas it was 0.29 (0.04-0.59) m/s per year or 7.61 (1.46-16.48) mmHg per year in the control group (both P < 0.05). Evolocumab use was associated with slow progression of AS and a low incidence of AS events in patients with moderate AS.

Dramatic Improvement of Pulmonary Tumor Thrombotic Microangiopathy in a Breast Cancer Patient Treated With Bevacizumab.

A 47-year-old woman diagnosed with stage IV left-sided breast cancer (T3N3aM1; OSS, HEP, LYM) 6 months back presented with respiratory distress. On admission, she developed respiratory failure, requiring 4 L of oxygen support. Pulmonary embolism was ruled out because computed tomography revealed no obvious pulmonary artery thrombus. Transthoracic echocardiography revealed a significant enlargement of the right ventricle and atrium. Pulmonary hypertension was confirmed via right heart catheterization. Pulmonary artery wedge aspiration cytology revealed adenocarcinoma cells. Based on these findings, we diagnosed the patient with pulmonary tumor thrombotic microangiopathy (PTTM) caused by breast cancer. Immediate chemotherapy (paclitaxel and bevacizumab) for breast cancer and concurrent treatment for pulmonary hypertension and disseminated intravascular coagulation were initiated. We could successfully control her condition with paclitaxel and bevacizumab for a year, and the patient survived for 1 year and 8 months. PTTM is a rare disease characterized by pulmonary hypertension and hypoxemia arising due to tumor embolization of the peripheral pulmonary arteries. PTTM is a rapidly progressing condition with no established treatment guidelines; its pathogenesis involves vascular endothelial growth factor (VEGF). This report highlighted the potential of bevacizumab, known for its anti-VEGF effect, in improving the pathological condition of patients with PTTM caused by breast cancer.

Association between sarcopenia and exercise capacity in patients with pulmonary hypertension without left heart disease.

BACKGROUND: Pulmonary hypertension (PH) has recently been described as a complex clinical syndrome affecting multiple organ systems, including the heart, lungs, and skeletal muscle, each of which plays an important role in exercise capacity. However, the relationship between exercise capacity and skeletal muscle abnormalities in patients with PH has not been fully elucidated. METHODS: We retrospectively analysed the exercise capacity and measures of skeletal muscle of 107 patients with PH without left heart disease (mean age 63 ± 15 years, 32.7% males, n = 30/6/66/5 in the clinical classification Group 1/3/4/5). RESULTS: Sarcopenia, low appendicular skeletal muscle mass index, low grip strength, and slow gait speed, determined by international criteria, were found in 15 (14.0%), 16 (15.0%), 62 (57.9%), and 41 (38.3%) patients, respectively. The mean 6-min walk distance of all patients was 436 ± 134 m and was independently associated with sarcopenia (standardised ß = -0.292, p < 0.001). All patients with sarcopenia showed reduced exercise capacity defined as 6-min walk distance < 440 m. Multivariable logistic regression analysis showed that each of the components of sarcopenia was associated with reduced exercise capacity (adjusted odds ratio and 95% confidence interval of appendicular skeletal muscle mass index: 0.39 [0.24-0.63] per 1 kg/m2, p = 0.006, grip strength: 0.83 [0.74-0.94] per 1 kg, p = 0.003, and gait speed: 0.31 [0.18-0.51] per 0.1 m/s, p < 0.001). CONCLUSIONS: Sarcopenia and its components are associated with reduced exercise capacity in patients with PH. A multifaceted evaluation may be important in the management of reduced exercise capacity in patients with PH.

Clinical impact of left ventricular systolic dysfunction in patients undergoing dialysis access surgery.

BACKGROUND: An arteriovenous fistula (AVF) is the most frequently used dialysis access for haemodialysis. However, it can cause volume loading for the heart and may induce circulatory failure when performed in patients with low cardiac function. This study aimed to characterise patients with low cardiac function when initiating dialysis and determine how cardiac function changes after the dialysis access surgery. METHODS: We conducted a retrospective observational study at two centres incorporating 356 patients with end-stage kidney disease who underwent echocardiography before the dialysis access surgery. RESULTS: An AVF and a subcutaneously fixed superficial artery were selected in 70.4% and 23.5% of 81 patients with reduced/mildly reduced (< 50%) left ventricular ejection fraction (LVEF), respectively, and in 94.2% and 1.1% of 275 patients with preserved (≥ 50%) LVEF (p < 0.001), respectively. Follow-up echocardiography was performed in 70.4% and 38.2% of patients with reduced/mildly reduced and preserved LVEF, respectively, which showed a significant increase in LVEF (41 ± 9-44 ± 12%, p = 0.038) in patients with reduced/mildly reduced LVEF. LVEF remained unchanged in 12 patients with reduced/mildly reduced LVEF who underwent subcutaneously fixed superficial artery (30 ± 10-32 ± 15%, p = 0.527). Patients with reduced/mildly reduced LVEF had lower survival rates after surgery than those with preserved LVEF (p = 0.021 for log-rank). CONCLUSION: The LVEF subcategory was associated with dialysis access selection. After the dialysis access surgery, LVEF was increased in patients with reduced/mildly reduced LVEF. These results may help select dialysis access for patients initiating dialysis.

Impact of grip strength and gait speed on exercise tolerance in patients with pulmonary hypertension without left heart disease.

Patients with pulmonary hypertension (PH) suffer from poor exercise tolerance due to impaired oxygenation and/or reduced cardiac output. However, the relationship between exercise tolerance and physical function remains unclear. The purpose of this study was to investigate the relationship between exercise tolerance and physical function in patients with PH. A total of 94 patients without left heart disease (61.3 ± 14.7 years old, 69.1% females, 22/8/60/4 patients with Group 1/3/4/5 PH) were retrospectively analysed. Physical function was measured using muscle strength (grip strength, knee extension muscle strength), balance function (one-leg standing time), and gait speed within 7 days of cardiac catheterization. Exercise tolerance was measured using the 6-min walking distance (6-MWD). A total of 194 6-MWD measurements and the corresponding physical function were evaluated in 94 patients. Multivariable linear regression analysis using adaptive-LASSO methods indicated that the World Health Organization functional classification, pulmonary vascular resistance, mixed venous oxygen saturation, grip strength, and gait speed were independently associated with the 6-MWD. Low grip strength (< 28 kg for males and < 18 kg for females; adjusted odds ratio and 95% confidence interval: 2.06 [1.30-3.26], p = 0.002), and slow gait speed (< 1.0 m/s for both sexes; 13.33 [3.61-49.19], p < 0.001) were independent predictors of poor exercise tolerance (6-MWD < 440 m) in a logistic regression analysis. Grip strength and gait speed as measures of physical function, pulmonary vascular resistance, and mixed venous oxygen saturation were associated with exercise tolerance in patients with PH without left heart disease.

A Simple Risk Score to Differentiate Between Coronary Artery Obstruction and Coronary Artery Spasm of Patients With Acute Coronary Syndrome Without Persistent ST-Segment Elevation.

BACKGROUND: The aim of this study was to create a risk scoring model to differentiate obstructive coronary artery (CA) from CA spasm in the etioology of acute coronary syndrome (ACS).Methods and Results: We included 753 consecutive patients with ACS without persistent ST-segment elevation (p-STE). The exclusion criteria were: (1) out-of-hospital cardiac arrest; (2) cardiogenic shock; (3) hemodialysis; (4) atrial fibrillation/flutter; (5) severe valvular disease; (6) no coronary angiography; (7) non-obstructive coronary artery without "definite" vasospastic angina definition; and/or (8) missing data. From the multivariate logistic regression analysis for prediction of obstructive CA, an integer score of 2 to each 0.5 increment in odds ratio was given, and values were divided into quartiles according to the total score. The scores were as follows: age >70 years (6 points), non-STE myocardial infarction (9 points), diabetes mellitus (5 points), B-type natriuretic peptide >90 pg/mL (7 points), neutrophil to lymphocyte ratio >2 (5 points), and high-density lipoprotein cholesterol <50 mg/dL (5 points). CA spasm-induced ACS occurred in 50.0% in Quartile 1 (total score: 0-13), 20.5% in Quartile 2 (total score: 14-19), 4.9% in Quartile 3 (total score: 20-26), and 2.2% in Quartile 4 (total score: 27-37) (P<0.001), indicating that a total score of <20 was a potential clinical indicator of CA spasm-induced ACS. CONCLUSIONS: CA spasm-induced ACS should be suspected if a total score of <20, and a spasm provocation test was being considered.

Independent Predictors of Major Adverse Cardiovascular Events at 3 Years after Aortoiliac Stent Implantation.

PURPOSE: To identify the risk factors for major adverse cardiovascular events (MACEs) in real-world practice for symptomatic peripheral artery disease in Japan. MATERIALS AND METHODS: Data on Japanese patients (N = 880) from the Observational Prospective Multicenter Registry Study on Outcomes of Peripheral Arterial Disease Patients Treated by Angioplasty Therapy for Aortoiliac Artery who underwent de novo aortoiliac stent placement. The 3-year risk of incident MACEs was investigated. RESULTS: The median age of the patients was 72.6 years (range, 34-97 years), and 83.1% of the patients were men. The patients had the following conditions: smoking (35.6%), hypertension (94.1%), dyslipidemia (81.7%), diabetes (48.0%), renal failure on dialysis (12.6%), myocardial infarction (12.7%), stroke (15.8%), and chronic limb-threatening ischemia (7.1%). Femoropopliteal lesions were present in 38.8% of the limbs with aortoiliac lesions. The 3-year rate of freedom from MACEs was 89.1%. Baseline characteristics, such as age, renal failure on dialysis, myocardial infarction, stroke, and femoropopliteal lesions, were independently associated with the risk of incident MACEs. When the study population was stratified according to these risk factors, the rate of MACEs was highest in patients with at least 3 risk factors (32.9% at 3 years). CONCLUSIONS: The 3-year rate of freedom from MACEs was reported. Baseline characteristics, such as age, renal failure on dialysis, myocardial infarction, stroke, and femoropopliteal lesions, are independent risk factors for MACEs after aortoiliac stent placement.

Clinical utility and safety of biopsy forceps for intestinal endoscopes during endovascular treatment.

A 76-year-old female who had a history of endovascular treatment (EVT) for her left superficial femoral artery with endovascular stent grafts [VIABAHN (W. L. Gore & Associates, Inc., DE, USA)] suddenly experienced intermittent claudication of her left leg. Angiography revealed total occlusion of previous stent grafts, and a thrombus aspiration catheter was used after crossing the guidewire. Since retrograde angiography using a thrombus aspiration catheter revealed a large residual thrombus at the distal edge of the previous stent even after several thrombus aspirations, biopsy forceps for intestinal endoscopes [Radial Jaw (Boston Scientific, MA, USA)] were successfully used to remove that thrombus. After balloon inflation under distal protection, angiography revealed a large residual thrombus at her left common femoral artery with a flow limiting of her deep femoral artery. Again, biopsy forceps were successfully used to remove that thrombus. In this case series, we reported a total of 11 cases which underwent EVT using biopsy forceps for intestinal endoscopes [Radial Jaw (Boston Scientific, MA, USA)]. Of the 11 cases, eight underwent EVT using biopsy forceps for thrombus removal, two underwent calcification removal in severely calcified lesions, and one underwent removal of a detached guidewire. There were no major adverse limb events (MALEs) except for one patient who underwent major amputation after EVT. One MALE occurred independently of biopsy forceps use because biopsy forceps were used only to remove the detached wire. Biopsy forceps for intestinal endoscopes were clinically useful and safe for EVT.

Feasibility and safety of transradial balloon aortic valvuloplasty in patients with severe aortic stenosis.

Balloon aortic valvuloplasty (BAV) was developed as a technique to treat aortic stenosis (AS) and is associated with significant improvements in aortic valve area and trans-aortic valve gradient in the early and immediate periods after the procedure. BAV is commonly performed using a trans-femoral retrograde approach; however, trans-femoral access is associated with frequent access-site bleeding. Among 146 patients with symptomatic severe AS who were treated with BAV in our institution, 123 patients received BAV treatment via a trans-radial approach using a 7-Fr Glidesheath. The balloon size was 16-20 mm for all patients. Echocardiograms were obtained before and after BAV. Patients who received BAV alone (n = 119) were followed up for 3 months, and major adverse events (stroke, re-hospitalization for heart failure, and death) and procedural complications were recorded. At post-procedural echocardiography, the mean trans-valvular gradient (49.7 ± 21.5-42.5 ± 17.6 mmHg; p < 0.0001) was reduced significantly. All patients in this study did not die or require valve surgery within the first 7 days after BAV. Successful BAV was obtained in 45.6% of the patients. No patients had severe aortic insufficiency or BAV access-site bleeding. Three patients died suddenly and 4 patients were readmitted for heart failure. Trans-radial BAV is safe and may be useful as a bridging therapy for trans-catheter aortic valve replacement or surgical aortic valve replacement.

A case of a coronary covered stent for repeated restenosis at the anastomosis site between saphenous vein graft and graft prosthesis.

A 56-year-old man was admitted with a diagnosis of non-ST-segment elevation myocardial infarction, after surgery for total arch replacement, aortic root replacement with a mechanical aortic valve, and coronary artery reconstruction by the Piehler method for acute aortic dissection. Coronary angiography (CAG) revealed a 99% stenosis of the anastomosis site between the J Graft (Japan Lifeline, Tokyo, Japan) and the saphenous vein graft (SVG), which was distally sutured to his right coronary artery (posterior descending artery). After percutaneous coronary intervention (PCI) with a drug-eluting stent to the anastomosis site, repeated in-stent restenosis unfortunately occurred. Despite repeated PCIs, he was again admitted due to exertional angina pectoris, with proven inferior myocardial ischemia by stress myocardial perfusion imaging. We therefore decided to use a coronary covered stent for the anastomosis site to seal neointimal proliferation. GRAFTMASTER 2.8/19 mm (Abbott, CA, USA) was implanted in the anastomosis site, and a follow-up CAG one-year later revealed that the covered stent was clearly opened. To the best of our knowledge, this is the first paper to demonstrate the usefulness of a covered stent for repeated restenosis of the anastomosis site between SVG and graft prostheses. .

CVIT expert consensus document on primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) update 2022.

Primary Percutaneous Coronary Intervention (PCI) has significantly contributed to reducing the mortality of patients with ST-segment elevation myocardial infarction (STEMI) even in cardiogenic shock and is now the standard of care in most of Japanese institutions. The Task Force on Primary PCI of the Japanese Association of Cardiovascular Interventional and Therapeutics (CVIT) society proposed an expert consensus document for the management of acute myocardial infarction (AMI) focusing on procedural aspects of primary PCI in 2018. Updated guidelines for the management of AMI were published by the European Society of Cardiology (ESC) in 2017 and 2020. Major changes in the guidelines for STEMI patients included: (1) radial access and drug-eluting stents (DES) over bare-metal stents (BMS) were recommended as a Class I indication, (2) complete revascularization before hospital discharge (either immediate or staged) is now considered as Class IIa recommendation. In 2020, updated guidelines for Non-ST-Elevation Myocardial Infarction (NSTEMI) patients, the followings were changed: (1) an early invasive strategy within 24 h is recommended in patients with NSTEMI as a Class I indication, (2) complete revascularization in NSTEMI patients without cardiogenic shock is considered as Class IIa recommendation, and (3) in patients with atrial fibrillation following a short period of triple antithrombotic therapy, dual antithrombotic therapy (e.g., DOAC and single oral antiplatelet agent preferably clopidogrel) is recommended, with discontinuation of the antiplatelet agent after 6 to 12 months. Furthermore, an aspirin-free strategy after PCI has been investigated in several trials those have started to show the safety and efficacy. The Task Force on Primary PCI of the CVIT group has now proposed the updated expert consensus document for the management of AMI focusing on procedural aspects of primary PCI in 2022 version.

Admission free-fatty acid level is a predictor of the mid-term worsening renal function in patients with ST-segment elevation myocardial infarction.

Whether free fatty acids (FFAs), which are generators of reactive oxygen species and substrates of cytotoxic lipid peroxidation products in proximal tubules of the kidney, can be a predictor of worsening renal function (WRF) is not fully elucidated. A total of 110 patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention within 24 h after symptom onset were included. The exclusion criteria were out-of-hospital cardiac arrest, vasospastic angina, hemodialysis, and/or lack of data. FFAs and serum cystatin C were measured on admission, and urinary liver-type fatty acid-binding protein (L-FABP) was measured 3 h after admission. WRF, defined as an increase in serum creatinine by ≥ 0.3 mg/dL for 2-year follow-up, was observed in 16 patients (15%). A multivariate logistic regression analysis (a stepwise algorithm) revealed that the FFA level was an independent predictor of WRF (P = 0.024). The FFA level was associated with WRF adjusted after serum cystatin C (odds ratio [OR]: 1.378 per 1 mEq/L, P = 0.017), L-FABP (OR: 1.370 per 1 mEq/L, P = 0.016), or the Mehran contrast-induced nephropathy (CIN) risk score (OR: 1.362 per 1 mEq/L, P = 0.021). The FFA level was inversely associated with the change in estimated glomerular filtration rate level for 2 years (R2 = 0.051, P = 0.018). The FFA level on admission was associated with the mid-term WRF in patients with STEMI.

Selexipag for the treatment of chronic thromboembolic pulmonary hypertension.

BACKGROUND: Treatment options for inoperable chronic thromboembolic pulmonary hypertension (CTEPH) remain limited. Selexipag, an oral selective IP prostacyclin receptor agonist approved for pulmonary arterial hypertension, is a potential treatment option for CTEPH. METHODS: In this multicentre, randomised, double-blind, placebo-controlled study, 78 Japanese patients with inoperable CTEPH or persistent/recurrent pulmonary hypertension after pulmonary endarterectomy and/or balloon pulmonary angioplasty were randomly assigned to receive placebo or selexipag. The primary end-point was the change in pulmonary vascular resistance (PVR) from baseline to week 20. Secondary end-points were changes in other haemodynamic parameters: 6-min walk distance (6MWD), Borg dyspnoea scale score, World Health Organization (WHO) functional class, EuroQol five-dimension five-level tool and N-terminal pro-brain natriuretic peptide. RESULTS: The change in PVR was -98.2±111.3 dyn·s·cm-5 and -4.6±163.6 dyn·s·cm-5 in the selexipag and placebo groups, respectively (mean difference -93.5 dyn·s·cm-5; 95% CI -156.8 to -30.3; p=0.006). The changes in cardiac index (p<0.001) and Borg dyspnoea scale score (p=0.036) were also significantly improved over placebo. 6MWD and WHO functional class were not significantly improved. The common adverse events in the selexipag group corresponded to those generally observed following administration of a prostacyclin analogue. CONCLUSION: Selexipag significantly improved PVR and other haemodynamic variables in patients with CTEPH, although exercise capacity remained unchanged. Further large-scale investigation is necessary to prove the role of selexipag in CTEPH.

Subclavian artery pseudoaneurysm in vascular Behcet's disease repaired using endovascular treatment: A case report of the clinical course over 10 years.

The vascular involvement in patients with Behcet's disease is defined as vascular Behcet's disease, which can greatly influence the prognosis. However, there are few reports on endovascular treatment (EVT) for subclavian pseudoaneurysms with long-term prognosis over 10 years. We present the case of a 42-year-old man with left subclavian artery pseudoaneurysm due to vascular Behcet's disease who was treated with EVT along with immunosuppressive therapies. Subsequently, 8 years after, the aneurysm recurred in the stent with stent fracture. Therefore, additional EVT was performed. We present the details of the patient's clinical course over 10 years after the EVT. .

Thrombotic Lesions are Associated with Poor Outcomes after Endovascular Treatment in Patients with Non-Acute Aortoiliac Total Occlusions.

AIM: The post-endovascular treatment outcomes of thrombotic lesions remain unclear. This study aimed to investigate the effects of thrombotic lesions on post-endovascular treatment outcomes in patients with non-acute aortoiliac total occlusions. METHODS: This subanalysis of a multicenter prospective observational registry study included patients from 64 institutions in Japan between April 2014 and April 2016. A total of 346 patients (394 limbs; median age, 72 years), including 186 men, underwent endovascular treatment for non-acute aortoiliac total occlusions and were included. The patients were classified as having thrombotic or non-thrombotic lesions. The primary (1-year primary patency rate) and secondary (1-year overall survival rate) endpoints were evaluated. RESULTS: Thrombotic lesions were identified in 18.5% (64/346) of the patients. The 1-year primary patency (85.9% versus 95.4%, log-rank p＜.001) and overall survival (90.6% versus 97.9%, log-rank p=.003) rates were significantly lower in the thrombotic group than in the non-thrombotic group. Thrombotic lesions had significant effects on the post-endovascular treatment outcomes, with adjusted hazard ratios of 3.91 (95% confidence interval, 1.64-9.34, p=.002) for primary patency and 4.93 (95% confidence interval, 1.59-15.3, p=.006) for all-cause mortality. CONCLUSIONS: Thrombotic lesions were associated with 1-year restenosis and all-cause mortality after endovascular treatment for non-acute aortoiliac total occlusions. Endovascular treatment strategies should be carefully planned for patients with thrombotic lesions.
