Mineralocorticoid exposure and receptor activity modulate microvascular endothelial function in African Americans with and without hypertension
Prior work suggests blood pressure in African Americans is more sensitive to the effects of aldosterone than in Caucasians. This mechanism may relate to a negative response of the vascular endothelium to aldosterone, including reduced glucose-6-phosphate dehydrogenase (G6PD) activity. Thirty-three African Americans (11 hypertensives, 22 controls) without evidence of diabetes or metabolic syndrome completed the protocol. The protocol included measurement of in vivo microvascular endothelial function by digital pulse arterial tonometry and ex vivo measurement of endothelial function by videomicroscopy of arterioles obtained ...

Venous thromboembolism in systemic autoimmune diseases: A narrative review with emphasis on primary systemic vasculitides
Venous thromboembolism (VTE) is a prevalent multifactorial health condition associated with significant morbidity and mortality. Population-based epidemiological studies have revealed an association between systemic autoimmune diseases and deep venous thrombosis (DVT)/VTE. The etiopathogenesis of increased risk of VTE in systemic autoimmune diseases is not entirely clear but multiple contributors have been explored, especially in the context of systemic inflammation and disordered thrombogenesis. Epidemiologic data on increased risk of VTE in patients with primary systemic vasculitides (PSV) have accumulated in recent year...

The validity of ICD codes coupled with imaging procedure codes for identifying acute venous thromboembolism using administrative data
In conclusion, when coupled with relevant imaging codes, VTE diagnostic codes obtained from administrative data provide a relatively sensitive and very specific method to ascertain acute VTE. (Source: Vascular Medicine)

Evaluation and management of symptomatic isolated spontaneous celiac trunk dissection
In conclusion, initial conservative treatment seems adequate for most patients with ISCTD. Long-term follow-up is mandatory, owing to the risk of later progression to aneurysm. (Source: Vascular Medicine)

The development and pilot randomised controlled trial of a group education programme for promoting walking in people with intermittent claudication
The aim of this study was to develop and pilot a group education programme for promoting walking in people with intermittent claudication. Patient focus groups (n=24) and literature reviews were conducted to inform the development of the education programme, which involves a three-hour group-based education workshop and follow-up telephone support. A pilot study was subsequently conducted in which 23 new patients (Rutherford category 1–3) were randomly assigned to usual care (control) or usual care plus the education programme. Outcomes were assessed at baseline and six weeks including daily steps (tri-axial accelero...

Community-based walking exercise for peripheral artery disease: An exploratory pilot study
Supervised walking exercise is an effective treatment to improve walking ability of patients with peripheral artery disease (PAD), but few exercise programs in community settings have been effective. The aim of this study was to determine the efficacy of a community-based walking exercise program with training, monitoring and coaching (TMC) components to improve exercise performance and patient-reported outcomes in PAD patients. This was a randomized, controlled trial including PAD patients (n=25) who previously received peripheral endovascular therapy or presented with stable claudication. Patients randomized to the inter...

Association between low ankle-brachial index and accelerometer-derived sedentary and exercise time in the asymptomatic general population
Sedentary behavior is an adverse health risk factor that is independent of physical activity. The relationship between sedentary behavior, exercise activity and the ankle-brachial index (ABI) is not well understood. We analyzed data from the National Health and Nutrition Examination Survey (NHANES) 2003–2004. Accelerometer data were used to quantify exercise and sedentary time for each participant. A low ABI was defined as a value <1.0 (including borderline values). Multi-variable adjusted logistic regression analyses were performed with sedentary and exercise times as independent variables, adjusting for importan...

Distinct effects of losartan and atenolol on vascular stiffness in Marfan syndrome
We conducted a randomized, double-blind trial of losartan (100 mg QD) versus atenolol (50 mg QD) for 6 months in adults with Marfan syndrome. Carotid-femoral pulse wave velocity (PWV), central augmentation index (AIx), aortic diameter and left ventricular (LV) function were assessed with arterial tonometry and echocardiography. Thirty-four subjects (18 female; median age 35 years, IQR 27, 45) were randomized. Central systolic and diastolic blood pressure decreased comparably with atenolol and losartan (p = 0.64 and 0.31, respectively); heart rate decreased with atenolol (p = 0.02), but not with losartan. PWV decreased in p...
