RESUMO
BACKGROUND: Individuals with severe motor and intellectual disabilities have become an aging population, and high cancer morbidity and mortality are critical issues affecting their survival. Cancer screening is a crucial method of resolving this issue; however, a suitable screening method for them has not been established. METHODS: We used ultrasonography alone and performed breast cancer screening for women over 30 years old in our facility from 2016 to 2023. We observed the outcomes and calculated the recall/detection rate in this screening. RESULTS: Three cases among 379 tested positive in this screening, all of which underwent radical surgery. They are alive and well without relapse present. We detected these breast cancer cases with a low recall rate. CONCLUSION: We were able to successfully detect breast cancer cases using ultrasonography alone. Ultrasonography is an effective and feasible tool for breast cancer screening in individuals with severe motor and intellectual disabilities.

PURPOSE: The purpose of the J-SUPREME (J-S) and J-SUPREME II (J-SII) trials was to evaluate the performance of the Jetstream Atherectomy System for the treatment of Japanese patients with symptomatic occlusive atherosclerotic lesions in the superficial femoral and popliteal arteries. MATERIALS AND METHODS: The J-S and J-SII trials were both prospective, multicenter, single-arm clinical trials. Patients in J-S underwent Jetstream atherectomy followed by percutaneous transluminal angioplasty (PTA), whereas those in J-SII had adjunctive drug-coated balloon (DCB) treatment following atherectomy. Patients were adults with Rutherford category 2, 3, or 4 and had stenotic, restenotic, or occlusive lesion(s) with a degree of stenosis ≥70 in the superficial femoral artery and/or proximal popliteal artery. In J-S, lesions were required to be calcified, and in J-SII lesions were required to be severely calcified. RESULTS: A total of 50 patients were enrolled in J-S (mean age 72.3±8.7 years, lesion length 82.0±41.5 mm, 36% calcification PACSS Grade 3, 22% Grade 4) and 31 patients in J-SII (mean age 72.5±7.7 years, lesion length 122.6±55.6 mm, 19.4% calcification PACSS Grade 3, 77.4% Grade 4). No bailout stenting or bypass conversions were required. No major adverse events (MAEs) were reported for either trial through 1 month. The 6-month primary patency for J-S, with PTA alone following atherectomy, was 40.4% (19/47). The 6-month primary patency for J-SII, with DCB treatment following atherectomy, was 96.7% (29/30). At 6-month post-procedure, 79.2% (38/48) of patients in J-S, and 100% (30/30) of patients in J-SII had improved by at least 1 Rutherford category. CONCLUSION: J-SUPREME trial results demonstrate procedural safety and efficacy of the Jetstream Atherectomy System and J-SII showed sustained patency through 6 months following combination treatment with Jetstream atherectomy and DCB.

Endovascular treatment (EVT) is the main treatment for peripheral artery disease (PAD). Despite advances in device development, the restenosis rate remains high in patients with femoropopliteal lesions (FP). This study aimed to evaluate the effectiveness of exercise training in reducing the 1-year in-stent restenosis rate of bare metal nitinol stents for FPs. This prospective, randomized, open-label, multicenter study was conducted from January 2017 to March 2019. We randomized 44 patients who had claudication with de novo stenosis or occlusion of the FP into an intensive exercise group (n = 22) and non-intensive exercise group (n = 22). Non-intensive exercise was defined as walking for less than 30 min per session, fewer than three times a week. We assessed exercise tolerance using an activity meter at 1, 3, 6, and 12 months, and physiotherapists ensured maintenance of exercise quality every month. The primary endpoint was instant restenosis defined as a peak systolic velocity ratio > 2.5 on duplex ultrasound imaging. Kaplan-Meier analysis was used to evaluate the data. There were no significant differences in background characteristics between the groups. Six patients dropped out of the study within 1 year. In terms of the primary endpoint, intensive exercise significantly improved the patency rate of bare nitinol stents at 12 months. The 1-year freedom from in-stent restenosis rates were 81.3% in the intensive exercise group and 47.6% in the non-intensive exercise group (p = 0.043). No cases of stent fracture were observed in the intensive exercise group. Intensive exercise is safe and reduces in-stent restenosis in FP lesions after endovascular therapy for PAD. Clinical trial registration: University Hospital Medical Information Network Clinical Trials Registry (No. UMIN 000025259).

OBJECTIVE: The aim of this study was to assess the impact of baseline and updated nutritional status on prognosis in patients with chronic limb threatening ischaemia (CLTI) undergoing revascularisation. METHODS: The clinical database of the Surgical reconstruction versus Peripheral INtervention in pAtients with critical limb isCHemia (SPINACH) study, a prospective, multicentre, observational study, was used. The current analysis included 499 patients who underwent endovascular therapy or surgical reconstruction for CLTI. Nutritional status at baseline was evaluated using the Geriatric Nutritional Risk Index (GNRI; baseline GNRI). A GNRI <82 points indicates major nutrition related risk. GNRI was also calculated at 1, 3, 6, 12, 24, and 36 months after revascularisation (updated GNRI). The association between baseline and updated GNRIs and the mortality risk was analysed with the Cox regression model. RESULTS: Mean ± standard deviation (SD) GNRI at baseline was 89.9 ± 9.8 points. The proportion of patients alive with a GNRI ≥82 points was 78% (95% confidence interval [CI] 74-81) at baseline but gradually decreased during follow up, finally reaching 19% (95% CI 0-42) at 36 months. In patients with a GNRI <82 points at baseline, a GNRI of ≥82 points was increased to 37% (95% CI 6-68) 12 months after revascularisation. In the multivariable analysis, baseline and updated GNRIs were associated with a reduced mortality risk independently of each other; the adjusted hazard ratios per 1 SD were 0.80 (95% CI 0.65-0.98; p = .031) and 0.66 (95% CI 0.49-0.91; p = .015), respectively. Similar findings were observed when nutritional status was evaluated using the Controlling Nutritional Stats (CONUT) score, except for the association between its updated value and mortality risk, which marginally lost significance. CONCLUSION: There was still room for improvement in nutritional status after revascularisation for patients with CLTI. Updated GNRI was associated with death independently of baseline GNRI.

Chronic kidney disease is a prognostic factor for cardiovascular disease. Worsening renal function (WRF), specifically, is an important predictor of mortality in patients with acute myocardial infarction undergoing primary percutaneous coronary intervention (PCI). We evaluate the prognostic impact of mid-term WRF after PCI on future cardiovascular events. We examined the renal function data of 1086 patients in the first year after PCI using the SHINANO 5-year registry. Patients were divided into two groups, mid-term WRF and non-mid-term WRF, and primary outcomes were major adverse cardiovascular events (MACE) and death. Mid-term WRF was defined as an increase in creatinine (≥ 0.3 mg/dL) in the first year after PCI. Mid-term WRF was found in 101 patients (9.3%), and compared to non-mid-term WRF, it significantly increased the incidence of MACE (p < 0.001), and all-cause death (p < 0.001), myocardial infarction (p = 0.001). Furthermore, mid-term WRF patients had higher incidence of future heart failure (p < 0.001) and new-onset atrial fibrillation (p = 0.01). Patients with both mid-term WRF and chronic kidney disease had increased MACE compared to patients with either condition alone (p < 0.001). Similarly, patients with mid-term WRF and acute kidney injury had increased MACE compared to patients with either condition alone (p < 0.001). Multivariate Cox regression analysis revealed mid-term WRF as a strong predictor of MACE (hazard ratio: 2.50, 95% confidence interval 1.57-3.98, p < 0.001). Mid-term WRF after PCI negatively affects MACE, as well as future admission due to heart failure and new-onset atrial fibrillation, chronic kidney disease, and acute kidney injury.

OBJECTIVES: We sought to assess whether balloon angioplasty (BA) alone for small femoropopliteal disease improved the outcome following endovascular therapy as compared with stent implantation. BACKGROUND: The optimal strategy of endovascular therapy for small vessel arteries in femoropopliteal disease remains unclear. METHODS: We performed a multicenter retrospective analysis of 337 consecutive patients (371 limbs) with femoropopliteal arteries 4.0 mm or less in diameter and 150 mm or less in length. RESULTS: Cumulative 3-year incidence of primary patency was significantly higher in the BA group than in the stent group (53.8% vs. 34.2%, P = 0.002). While assisted-primary patency and freedom from any major adverse limb events were also significantly higher in the BA group than in the stent group (70.9% vs. 44.2%, P < 0.001 and 60.6% vs. 36.4%, P = 0.001, respectively), secondary patency did not significantly differ between the two groups (86.9% vs. 86.9%, P = 0.67). Predictors of restenosis were diabetes mellitus (hazard ratio [HR], 1.61; 95% confidence interval [CI], 1.14-2.31; P = 0.01), no administration of cilostazol (HR, 1.50; 95% CI, 1.07-2.13; P = 0.02), stent implantation (HR, 1.68; 95% CI, 1.15-2.41; P = 0.01), and lesion length >75.0 mm(HR, 2.09; 95% CI, 1.50-2.92; P < 0.001). CONCLUSIONS: Lesions in small (<4.0 mm diameter) FP vessels demonstrated better primary patency at 3 years when successfully treated with balloon angioplasty alone as opposed to routine or bailout stenting. This difference was especially pronounced for lesions 75 to 150 mm in length.

Although coronary artery disease (CAD) is common in patients with heart failure (HF), little is known about the prognostic significance of coronary lesion complexity in patients with prior HF undergoing percutaneous coronary intervention (PCI). The aim of this study was to investigate whether the coronary Synergy between Percutaneous Coronary Intervention with TAXus and Cardiac Surgery (SYNTAX) score could improve risk stratification in HF patients with CAD. Two hundred patients (mean age 73 ± 11 years, left ventricular ejection fraction 49 ± 15 %) with prior HF who underwent PCI were divided into two groups stratified by SYNTAX score (median value 12) and tracked prospectively for 1 year. The study endpoint was the composite of major adverse cardiovascular events (MACE), including all-cause death, myocardial infarction, stroke, and hospitalization for worsening HF. Adverse events were observed in 39 patients (19.5 %). Patients with high SYNTAX scores (n = 100) showed worse prognoses than those with low scores (n = 100) (26.0 vs. 13.0 %, respectively, P = 0.021). In multivariate Cox-regression analysis, SYNTAX score ≥12 was significantly associated with MACE (hazard ratio: 1.99, 95 % confidence interval: 1.02-3.97; P = 0.045). In patients with prior HF and CAD, high SYNTAX scores predicted a high incidence of MACE. These results suggest that the SYNTAX score might be a useful parameter for improving risk stratification in these patients.

BACKGROUND: Optimal medical therapy after endovascular therapy in patients with critical limb ischemia (CLI) remains unclear. Therefore, we investigated whether cilostazol reduce restenosis after balloon angioplasty for infrapopliteal lesions in CLI patients. METHODS: This study was performed as a multicenter, prospective, randomized, open-label, blinded-end point study with independent angiographic core laboratory adjudication. Sixty patients were eligible and 53 patients were enrolled and allocated. The primary end point was 3-month angiographic restenosis. The main secondary end points included major adverse limb event (MALE defined as requirement of any reintervention or major amputation), perioperative complications, major amputation, all-cause death, and hemorrhagic events. RESULTS: A total of 53 patients were randomized and all received their allocated intervention. Two patients in the cilostazol plus aspirin group and 1 in the aspirin group did not undergo any angioplasty for infrapopliteal stenotic lesions, and therefore were excluded from analysis. Finally, 38 vessels in 25 patients in the cilostazol plus aspirin group and as many cases in the aspirin group were included in the analysis. There were no significant differences in baseline characteristics between the 2 groups. The 3-month restenosis rate was 82% in the cilostazol + aspirin group and 81% in the aspirin group, with no significant difference (P = 0.91). The MALE rate was 11% in the cilostazol plus aspirin group and 8% in the aspirin group (P = 0.73). In addition, no significant difference was observed in any secondary points. CONCLUSIONS: Cilostazol did not reduce 3-month angiographic restenosis after balloon angioplasty for below-the-knee lesion in CLI patients.

Patients on hemodialysis (HD) have abnormalities of calcium-phosphate (CaP) homeostasis and high CaP product contributes to atherosclerosis pathogenesis and adverse events. Patients on HD with critical limb ischemia (CLI) are at risk for major amputation and death because of advanced systemic atherosclerotic disease. The aim of this study was to evaluate the relationship between CaP product and amputation-free survival (AFS) in CLI after endovascular treatment (EVT). We retrospectively analyzed 221 CLI patients on HD. In Kaplan-Meier analysis, AFS was significantly lower in patients with CaP product ⩾ 55 mg(2)/dL(2) compared to those with CaP product <55 mg(2)/dL(2) (54.3% vs 78.5%, p = 0.002). However, neither serum phosphate nor calcium levels were individually associated with AFS. In multivariate analysis, CaP product ⩾ 55 mg(2)/dL(2) was an independent predictor for AFS in CLI patients on HD (hazard ratio, 3.03; 95% confidence interval, 1.78-5.15; p-value < 0.001). We concluded abnormal CaP homeostasis was associated with lower AFS after EVT in CLI patients on HD, and can serve for their risk stratification.

The use of beta-blockers therapy has been recommended to reduce mortality in patients with left ventricular dysfunction after acute myocardial infarction (AMI). Primary percutaneous coronary intervention (PCI), which has become the mainstay of treatment for AMI, is associated with a lower mortality than fibrinolysis. The benefits of beta-blockers after primary PCI in AMI patients without pump failure are unclear. We hypothesized that oral beta-blocker therapy after primary PCI might reduce the mortality in AMI patients without pump failure. The assessment of lipophilic vs. hydrophilic statin therapy in acute myocardial infarction (ALPS-AMI) study was a multi-center study that enrolled 508 AMI patients to compare the efficacy of hydrophilic and lipophilic statins in secondary prevention after myocardial infarction. We prospectively tracked cardiovascular events for 3 years in 444 ALPS-AMI patients (median age 66 years; 18.2 % women) who had Killip class 1 on admission and were discharged alive. The primary endpoint was all-cause mortality. The 3-year follow-up was completed in 413 patients (93.0 %). During this follow-up, 21 patients (4.7 %) died. In Kaplan-Meier analysis, patients on beta-blockers had a significantly lower incidence of all-cause mortality (2.7 vs. 7.3 %, log-rank p = 0.025). After adjusting for the calculated propensity score for using beta-blockers, their use remained an independent predictor of all-cause mortality (hazard ratio 0.309; 95 % confidence interval 0.116-0.824; p = 0.019). In the statin era, the use of beta-blocker therapy after primary PCI is associated with lower mortality in AMI patients with Killip class 1 on admission.

Inflammatory biomarkers have been proposed for use in the risk stratification of patients with acute myocardial infarction (AMI). We examined the value of inflammatory biomarkers over clinical features for predicting cardiovascular (CV) events in stable outpatients with MI. We enrolled 430 post-MI patients and measured their levels of high-sensitivity C reactive protein (hs-CRP), growth differentiation factor-15 (GDF-15), and the interleukin-1 receptor family member called ST2 (ST2), one month after AMI. Patients were prospectively followed for 3 years. In our study cohort (mean age, 66 ± 12 years; left ventricular ejection fraction, 55 ± 13%), CV events were observed in 39 patients (9.1%). Kaplan- Meier analysis revealed that patients with high levels of GDF-15 (≥ 1221.0 ng/L) showed poorer prognoses than those with low levels of GDF-15 (< 1221.0 ng/L) (20.4% versus 3.6%, P < 0.001); hs-CRP and ST2 did not show a similar correlation with prognoses. GDF-15 remained associated with CV events after adjusting for age, chronic kidney disease, and B-type natriuretic peptide (hazard ratio, 1.001; 95% confidence interval, 1.000 - 1.001; P = 0.046). GDF-15 provided an incremental predictive value for CV events over clinical features (incremental value in global χ(2) = 43.81, P < 0.001). In outpatients with prior MI, GDF-15 was an independent indicator of CV events, unlike hs-CRP and ST2. GDF15 provided an incremental prognostic value over clinical features.

BACKGROUND: Atherosclerotic renal artery stenosis (ARAS) causes renovascular hypertension (HTN) and impairs renal function, leading to chronic kidney disease (CKD). The J-RAS study was a prospective, multicenter study to assess the clinical outcome of renal artery stenting for up to 1 year in Japanese patients with ARAS. METHODS AND RESULTS: One hundred and forty-nine patients were enrolled between November 2010 and January 2013. The patients were classified into an HTN (n=121) group and a CKD (n=108) group in the primary analysis. The primary efficacy endpoints were change in blood pressure for the HTN group and change in estimated glomerular filtration rate (eGFR) for the CKD group at 1 months. The primary safety endpoint was freedom from major cardiovascular or renal events at 12 months. In the HTN group, the mean systolic blood pressure (SBP) significantly decreased from 161.6 ± 21 mmHg at baseline to 137.0 ± 21 mmHg (P<0.0001). In the CKD group, there was no significant difference in eGFR from 40.7 ± 10 ml·min(-1)·1.73 m(-2)at baseline to 40.8 ± 13 ml·min(-1)·1.73 m(-2)(P=0.32). The primary safety endpoint was 89.4% at 12 months. CONCLUSIONS: In the J-RAS trial, significant SBP reduction was seen in the HTN group, and stabilization of renal function in the CKD group. Renal artery stenting for ARAS is safe and effective in Japanese patients.

BACKGROUND: Statins reduce the incidence of cardiovascular events, but no randomized trial has investigated the best statins for secondary prevention. We compared the efficacy of hydrophilic pravastatin with that of lipophilic atorvastatin in patients with acute myocardial infarction (AMI). METHODS AND RESULTS: A prospective, multicenter study enrolled 508 patients (410 men; mean age, 66.0 ± 11.6 years) with AMI who were randomly assigned to atorvastatin (n=255) or pravastatin (n=253). The target control level of low-density lipoprotein cholesterol (LDL-C) was <100 mg/dl, and patients were followed for 2 years. The primary endpoint was the composite of death due to any cause, non-fatal myocardial infarction, non-fatal stroke, unstable angina or congestive heart failure requiring hospital admission, or any type of coronary revascularization. The primary endpoint occurred in 77 patients (30.4%) and in 80 patients (31.4%) in the pravastatin and atorvastatin groups, respectively (hazard ratio, 1.181; 95% confidence interval: 0.862-1.619; P=0.299), whereas greater reductions in serum total cholesterol and LDL-C were achieved in the atorvastatin group (P<0.001 for each). Changes in hemoglobin A1c, brain natriuretic peptide, and creatinine were not significant between the 2 regimens, and safety and treatment adherence were similar. CONCLUSIONS: On 2-year comparison of hydrophilic and lipophilic statins there was no significant difference in prevention of secondary cardiovascular outcome.

BACKGROUND: The dysregulation of systemic blood pressure (BP) variation or cardiac neuroadrenergic dysfunction is associated with adverse cardiovascular events. We aimed to clarify the prognostic significance of neuroadrenergic dysfunction for cardiovascular events in patients with acute myocardial infarction (AMI). METHODSâANDâRESULTS: We enrolled 63 AMI patients (mean age, 67±12 years) underwent ambulatory BP monitoring (ABPM) and cardiac iodine-(123)metaiodobenzylguanidine (MIBG) imaging within 4 weeks after AMI onset. We analyzed the circadian BP pattern and heart-to-mediastinum (H/M) MIBG uptake ratio. All the patients were followed for 2 years. The study endpoint was a composite of major adverse cardiovascular events, including all-cause death, MI, coronary revascularization except for the MI culprit lesion, and stroke. Patients with a non-dipper pattern (n=29) or an H/M ratio <1.96 (n=28) had a worse prognosis than those with either a dipper pattern (n=34) or an H/M ratio ≥1.96 (n=35; log-rank, P=0.013 and 0.010, respectively). Patients with both a non-dipper pattern and an H/M ratio <1.96 (n=12) had a significantly worse prognosis than did the other patients (P=0.0020). CONCLUSIONS: Dysregulation of BP variation and cardiac MIBG uptake were associated with cardiovascular events following AMI.

We assessed the relationship between J waves and the ventricular morphology and function using cardiac magnetic resonance imaging (MRI). The 12-lead electrocardiograms (ECGs) of 105 consecutive patients who underwent cardiac MRI were reviewed, and those with signs of arrhythmogenic right ventricular cardiomyopathy, complete left bundle branch block, complete right bundle branch block, or chronic atrial fibrillation, where the J wave is difficult to distinguish, were excluded. The ECGs of the remaining 68 patients were analyzed for the presence of J waves. Ventricular morphologic abnormalities were identified on MRI, based on the largest short-axis diameter in the right and left ventricles (d-RVmax/d-LVmax), the area (a-RVmax/a-LVmax), and the ratio RV/LVmax. The percentage contraction of the RV (PC-RV) was used as a measure of ventricular function. Thirty-two patients (47.0 %) had J waves defined as QRS-ST junction elevation >0.1 mV from baseline in the inferior/lateral leads (J group; 56 ± 15 years; 19 males). Thirty-six patients (53.0 %) did not present J waves (NJ group; 58 ± 15 years; 27 males). The d-RVmax and a-RVmax in the J group were larger than those in the NJ group (41 ± 5.2 vs 36 ± 6.6 mm, P = 0.002 and 14 ± 2.9 vs 12 ± 3.4 cm(2), P = 0.022, respectively). The RV/LVmax ratio in the J group was larger than that in the NJ group (0.83 ± 0.15 vs 0.68 ± 0.15, P < 0.001). The PC-RV in the J group was smaller than that in the NJ group (0.28 ± 0.14 vs 0.36 ± 0.15, P = 0.013). J-wave amplitude was correlated positively with d-RVmax (P = 0.010) and negatively with PC-RV (P = 0.005). These results suggested that J waves are associated with right ventricular morphologic and functional abnormalities.

BACKGROUND: It remains unclear whether cilostazol, which has been shown to improve the clinical outcomes of endovascular therapy for femoropopliteal lesions, also reduces angiographic restenosis. METHODS AND RESULTS: The Sufficient Treatment of Peripheral Intervention by Cilostazol (STOP-IC) study investigated whether cilostazol reduces the 12-month angiographic restenosis rate after percutaneous transluminal angioplasty with provisional nitinol stenting for femoropopliteal lesions. Two hundred patients with femoropopliteal lesions treated from March 2009 to April 2011 at 13 cardiovascular centers were randomly assigned 1:1 to receive oral aspirin with or without cilostazol. The primary end point was 12-month angiographic restenosis rate. Secondary end points were the restenosis rate on duplex ultrasound, the rate of major adverse cardiac events, and target lesion event-free survival. Researchers evaluated all follow-up data and assessed the end points in a blinded fashion. The mean lesion length and reference vessel diameter at the treated segment were 128±86 mm and 5.4±1.4 mm, respectively. The frequency of stent used was similar between groups (88% versus 90% in the cilostazol and noncilostazol group, respectively, P=0.82). During the 12-month follow-up period, 11 patients died and 152 patients (80%) had evaluable angiographic data at 12 months. The angiographic restenosis rate at 12 months was 20% (15/75) in the cilostazol group versus 49% (38/77) in the noncilostazol group (P=0.0001) by intention-to-treat analysis. The cilostazol group also had a significantly higher event-free survival at 12 months (83% versus 71%, P=0.02), although cardiovascular event rates were similar in both groups. CONCLUSIONS: Cilostazol reduced angiographic restenosis after percutaneous transluminal angioplasty with provisional nitinol stenting for femoropopliteal lesions.

PURPOSE: To examine the prognosis of patients with intermittent claudication who received treatment with endovascular techniques. METHODS: A retrospective multicenter study was performed involving 2930 consecutive patients (2307 men; mean age 71.5±8.9 years) with intermittent claudication who underwent an endovascular procedure for a de novo iliofemoral artery lesion. The primary outcome measure was overall survival. The secondary outcomes were freedom from major adverse cardiovascular events (MACE: all-cause death, myocardial infarction, and stroke) and from major adverse cardiovascular and limb events (MACE with repeat revascularization or above-knee amputation of the target limb). Cox multivariate regression analysis of selected baseline characteristics, procedure-related complications, and medication use was performed to determine predictors for all-cause mortality. Positive predictors from this analysis were used to stratify patients into low- (1410, 48.1%), moderate- (1406, 48.0%), and high-risk (114, 3.9%) categories. RESULTS: The overall survival rates were 97.2%, 90.8%, and 83.4% at 1, 3, and 5 years, respectively. The cause of death was cardiovascular in 42.8% of cases. Freedom from MACE was 96.7%, 88.6%, and 77.3% at 1, 3, and 5 years, respectively. Cox multivariate regression analysis identified age, dialysis, left ventricular dysfunction, insulin-dependent diabetes, hematoma prolonging hospitalization, coronary artery disease, and superficial femoral plus iliac lesions as positive predictors of all-cause mortality. In the risk stratification analysis, the overall 5-year survival rate was significantly lower in high-risk patients compared to the other groups (90.1% vs. 78.6% vs. 53.5%, p<0.0001). CONCLUSION: The prognosis in patients with intermittent claudication after endovascular therapy was relatively good but extremely poor for the high-risk patient subgroup.

PURPOSE: To report long-term outcomes of endovascular therapy (EVT) for aortoiliac bifurcation lesions. METHODS: Patients enrolled in the multicenter REtrospective AnaLysis of Aorto-Iliac stenting (REAL-AI) registry in Japan were pooled. Of 2096 patients who underwent EVT for de novo aortoiliac disease between January 2005 and December 2009, 190 patients (148 men; mean age 70±9 years) had aortoiliac bifurcation lesions that were treated with stents, whose configuration (single, V, or kissing) and type (balloon-expandable or self-expanding) were subjected to regression analysis to determine any impact on primary patency along with other demographic, clinical, and lesion characteristics, including Trans-Atlantic Inter-Society Consensus II C/D classification. The primary endpoints were restenosis and target lesion revascularization (TLR). Secondary endpoints were all-cause death, major cardiovascular events, and major cardiovascular + limb events. RESULTS: The overall complication rate was 6.3%, and 1- and 5-year primary patency rates were 87% and 73%, respectively. Over a mean follow-up of 31±15 months, there were 36 (19.0%) restenoses, 22 (11.6%) TLRs, and 4 (2.1%) reocclusions; stent fracture (2, 1.1%) and major amputation (2, 1.1%) were rare. Only female gender [adjusted hazard ratio (AHR) 4.26, 95% CI 1.89 to 9.71, p<0.001] and residual diameter stenosis (AHR 1.04, 96% CI 1.01 to 1.06, p=0.01) were independent predictors of primary patency. CONCLUSION: Stenting for aortoiliac bifurcation lesions was found to be safe and effective. Neither stent configuration nor type appeared to affect vessel patency in true bifurcation lesions.

PURPOSE: To investigate the impact of angiosome-oriented revascularization on clinical outcomes in critical limb ischemia (CLI) patients excluding those with both diabetes and wound infection. METHODS: Using a retrospective multicenter database, a propensity score matching analysis was performed of 539 consecutive CLI patients (375 men; mean age 71±11 years) without concurrent wound infection and diabetes who underwent balloon angioplasty of isolated infrapopliteal lesions. Propensity score matching produced 2 groups of 182 patients each who underwent angiosome-oriented direct revascularization (123 men; mean age 72±11 years) or indirect revascularization (125 men; mean age 72±11 years). The groups were compared for wound healing rate, freedom from major adverse limb events (MALE), and amputation-free survival (AFS). RESULTS: In the overall population, indirect revascularization was performed in 36.6% (n=197). In the propensity matching analysis, the complete wound healing rate at 12 months was higher in the direct group than the indirect revascularization patients (75% vs. 64%, p=0.01), while freedom from MALE (p=0.99) and AFS (p=0.17) were not significantly different at up to 24 months. In multivariate analysis, indirect revascularization had an independent negative impact on wound healing (adjusted hazard ratio 0.7, p=0.008). CONCLUSION: After propensity matching analysis for CLI patients other than those with both diabetes and wound infection, the wound healing rate was higher after direct revascularization than after indirect revascularization, whereas MALE and AFS were not significantly different.

PURPOSE: To examine in claudicant patients with aortoiliac lesions the relationship between the post-exercise ankle-brachial index (ABI) and the peripheral fractional flow reserve (p-FFR), a physiological test that has heretofore been used to assess coronary and renal artery stenosis. METHODS: Sixteen male patients (mean age 68.1±7.5 years) with isolated iliac artery lesions detected by ultrasound in 17 limbs were enrolled in this study. Resting ABI was measured and a treadmill test was administered to measure the post-exercise ABI. During angiography, the p-FFR was measured using a pressure guidewire after administration of papaverine to induce hyperemia. Changes in the ABI during exercise and p-FFR at hyperemia were calculated. RESULTS: The mean resting ABI and post-exercise ABI were 0.87±0.12 and 0.65±0.24, respectively. There was no complication during the measurement of p-FFR. The mean p-FFR at hyperemia was 0.71±0.14. A significant linear correlation was observed between post-exercise ABI and p-FFR at hyperemia (r=0.857, p<0.001), which was stronger than the correlation between post-exercise ABI and peak-to-peak pressure gradient at hyperemia (r= -0.626, p=0.013). CONCLUSIONS: Measuring p-FFR appears to be a feasible and safe procedure, and there is a significant linear correlation between post-exercise ABI and p-FFR in aortoiliac lesions. The p-FFR was more accurate than a peak-to-peak pressure gradient in assessing the physiological significance of a stenosis. Though larger studies are required, p-FFR might be used to physiologically assess stenosis in PAD patients with isolated aortoiliac lesions.
