#1
Crystal Yin Tung Chan, Stephen Wing Keung Cheng
An abnormally high level of homocysteine (Hcy) has been consistently observed in the blood of abdominal aortic aneurysm (AAA) patients. However, the expression of Hcy in human AAA tissues has not been investigated. In this study, the expression of Hcy in aneurysmal tissues from AAA patients ( n=30) was compared with non-aneurysmal tissues from organ donors ( n=31) by dot blotting and immunohistochemistry. A significantly higher expression of Hcy was observed in AAA than control tissues ( p<0.001). Furthermore, the associations of methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism, detected by polymerase chain reaction-restriction fragment length polymorphism, with both AAA and tissue Hcy expression were evaluated...

The impact of heart failure (HF) on long-term survival in patients with critical limb ischemia (CLI) has not been well described. Outcomes stratified by left ventricular ejection fraction (EF) are also unknown. A single center retrospective chart review was performed for patients who underwent treatment for CLI from 2006 to 2013. Baseline demographics, procedural data and outcomes were analyzed. HF diagnosis was based on appropriate signs and symptoms as well as results of non-invasive testing. Among 381 CLI patients, 120 (31%) had a history of HF and 261 (69%) had no history of heart failure (no-HF)...

Hisato Takagi, Tomo Ando, Takuya Umemoto
We performed a meta-analysis to determine whether weekend admission and surgery for ruptured abdominal/thoracic aortic aneurysm (RAAA/RTAA) and acute aortic dissection (AAD) is associated with increased mortality. MEDLINE and EMBASE were searched from January 1946 to December 2016 using PubMed and OVID. Eligible studies were prospective or retrospective, comparative or cohort studies enrolling patients admitting or undergoing surgery for RAAA/RTAA/AAD and reporting mortality after weekend (including holiday) versus weekday admission/surgery...

Arterial distensibility, an independent predictor of cardiovascular events, is transiently increased with acute hyperglycemia (AHG) in healthy individuals. Whether this response interacts with physical inactivity remains unknown. We examined the effects of short-term bed rest (BR) on the response of carotid artery distensibility (CD) to AHG, and the influence of underlying changes in insulin resistance and blood volume. CD was assessed with ultrasonography before as well as 30 and 120 minutes following ingestion of 75 g of glucose prior to and after 3 days of BR in 15 healthy male volunteers...

Lymphedema, a chronic debilitating disease, is not always easily diagnosed. A total of 254 new patients ((217 women, 37 men), median (Q1-Q3) age 61 (46-72) years) were referred for suspected limb lymphedema to an exclusively lymphedema-dedicated department for a first consultation (January - March 2015) were included; among 118 with upper limb involvement, 100 (84.7%) were diagnosed with post-breast cancer therapy and four with primary lymphedemas; among 136 with lower limb involvement, 31 (22.8%) were diagnosed with primary lymphedemas and 35 (25...

Elderly patients with acute pulmonary embolism (PE) have higher mortality than non-elderly patients, but receive systemic fibrinolysis less frequently. In this sub-analysis of the SEATTLE II trial, we evaluated the efficacy and safety of ultrasound-facilitated, catheter-directed, low-dose fibrinolysis in elderly patients with submassive and massive PE. We compared patients ⩾65 years old with those <65 years old. Eligible patients had proximal PE and a right ventricular-to-left ventricular (RV/LV) diameter ratio ⩾0...

Since 2005, the American Board of Vascular Medicine (ABVM) endovascular examination has been used to certify vascular practitioners. Annual rigorous review has confirmed it is psychometrically valid and reliable. However, the evidence basis underlying the examination items has not been studied systematically. The aim of this study was to adjudicate class of recommendation (COR) and level of evidence (LOE) for the 2015 ABVM endovascular examination and establish an additional feedback mechanism for examination improvement based on contemporary evidence-based guidelines...

Endothelial dysfunction plays a major role in cardiovascular diseases and pulse amplitude tonometry (PAT) offers a non-invasive way to assess endothelial dysfunction. However, data about the reliability of PAT in cardiovascular patient populations are scarce. Thus, we evaluated the test-retest reliability of PAT using the natural logarithmic transformed reactive hyperaemia index (LnRHI). Our cohort consisted of 91 patients (mean age: 65±9.7 years, 32% female), who were divided into four groups: those with heart failure with preserved ejection fraction (HFpEF) ( n=25), heart failure with reduced ejection fraction (HFrEF) ( n=22), diabetic nephropathy ( n=21), and arterial hypertension ( n=23)...

This analysis compared the angiographic outcomes of patients treated with orbital atherectomy for calcified common femoral artery (CFA) and superficial femoral artery (SFA) disease. The ideal revascularization strategy for CFA disease is unknown. Endarterectomy has been considered the standard of care for CFA disease for over 50 years. Endovascular intervention is becoming more commonly used to revascularize the CFA given the advances in technology and the less invasive nature of the procedure. Patient demographics, lesion characteristics, and procedure data for all CONFIRM patients with at least one CFA lesion location ( n=147 patients; n=200 lesions) were compared to patients with at least one SFA lesion location ( n=1508 patients; n=2367 lesions)...

We examined how pain beliefs are related to symptom severity, expectations of risk/benefits, and baseline physical activity among claudicants. Eligible patients at the Michael E DeBakey Veterans Affairs Medical Center were administered questionnaires that measured: fear-avoidance beliefs (Fear-Avoidance Beliefs Questionnaire [FABQ]), walking impairment, baseline physical activity, claudication type, and risk/benefit attitudes. Among 20 participants, the median age was 69 years (IQR: 66-75). In our efforts to understand how fear-avoidance beliefs influenced physical activity among people with claudication, we found that 12 participants (63%) thought that the primary etiology of their pain was walking, while 18 (90%) people thought that walking would exacerbate their leg symptoms - suggesting that there was some confusion regarding the effects of walking on claudication...

Transcatheter aortic valve replacement (TAVR) is now an accepted pathway for aortic valve replacement for patients who are at prohibitive, severe and intermediate risk for traditional aortic valve surgery. However, with this rising uptrend and adaptation of this new technology, vascular complications and their management remain an Achilles heel for percutaneous aortic valve replacement. The vascular complications are an independent predictor of mortality for patients undergoing TAVR. Early recognition of these complications and appropriate management is paramount...
