Difference in right and left cardio-ankle vascular index as a useful marker for evaluation of leg ischemia in patients with lower extremity arterial disease.

Objectives: Cardio-ankle vascular index (CAVI) is a blood pressure-independent measure of heart-ankle pulse wave velocity and is used as an indicator of arterial stiffness. However, there is a paradox that CAVI is inversely associated with leg ischemia in patients with lower extremity arterial disease (LEAD). The aim of this study was to clarify the significance of the absolute value of left and right difference in CAVI (diff-CAVI).

Paradox of the Relationship between Cardio-Ankle Vascular Index and Ankle-Brachial Index in Patients with Lower Extremity Artery Disease.

Measurements of ankle-brachial index (ABI) and toe-brachial index (TBI) are standard examinations for evaluating arterial blood flow in lower extremities and diagnosing lower extremity artery disease (LEAD). It remains to be clarified whether cardio-ankle vascular index (CAVI), a blood pressure-independent parameter of arterial stiffness, is associated with ABI and TBI in patients with LEAD. The subjects were 165 outpatients with LEAD.

Peptides associated with hypertensive disorders of pregnancy as possible biomarkers for severity of lower extremity arterial disease.

Background And Aims: Seven circulating peptides, consisting of 18-28 amino acids, were identified as possible biomarkers of hypertensive disorders of pregnancy (HDP) in our previous study. However, it is unknown whether these peptides are relevant to cardiovascular disease. The purpose of this study was to clarify the relationships between serum levels of these peptides and leg arterial blood flow in patients with lower extremity arterial disease (LEAD).

Associations of habitual alcohol drinking with HDL cholesterol and D-dimer in patients with peripheral arterial disease.

Background: The risk of cardiovascular disease is lower in light-to-moderate alcohol drinkers than in nondrinkers in the general population. However, it remains to be clarified whether these beneficial effects of alcohol are shown in patients with peripheral arterial disease (PAD).

Methods: The subjects were 153 male outpatients with PAD and they were divided by frequency of drinking into nondrinkers, occasional drinkers (1-4 days/wk) and regular drinkers (5-7 days/wk).
