Long-Term Prognostic Risk in Lower Extremity Peripheral Arterial Disease as a Function of the Number of Peripheral Arterial Lesions.

Background: Although patients with peripheral artery disease (PAD) are known to have an increased risk of adverse prognosis, simple techniques to further risk-stratify PAD patients would be clinically useful. A plausible but unexplored factor to predict such risk would be greater disease burden, manifested as multiple lower extremity lesions. The aim of this study was to examine the association between having multiple versus isolated lower extremity PAD lesions and long-term prognosis.

Determinants of invasive treatment in lower extremity peripheral arterial disease.

Objective: Since it is unknown what factors are weighed in a clinician's decision to refer patients with symptomatic lower extremity peripheral arterial disease (PAD) for invasive treatment, we examined the relationship between health status, lesion location, and site variations and invasive treatment referral ≤1 year following diagnosis in patients with PAD.

Methods: This was a prospective observational cohort study on ambulatory patients that presented themselves at two vascular surgery outpatient clinics. A total of 970 patients with new symptoms of PAD or with an exacerbation of existing PAD symptoms that required clinical evaluation and treatment (Rutherford Grade I) were eligible, 884 consented and were included between March 2006 and November 2010.

Self-reported symptoms on questionnaires and anatomic lesions on duplex ultrasound examinations in patients with peripheral arterial disease.

Objective: Whether a typical patient and symptom profile is associated with proximal or distal lesions in lower extremity peripheral arterial disease (PAD) is unknown. Knowing which patient characteristics, exertional leg symptoms, and cardiovascular risk profile accompany the anatomic lesion location may facilitate a more tailor-made management of PAD.

Methods: This cross-sectional study comprised 701 patients from two vascular surgery outpatient clinics with new-onset symptoms of PAD (Fontaine 2) who underwent duplex ultrasound (DUS) examinations from March 2006 to March 2011.

Younger women with symptomatic peripheral arterial disease are at increased risk of depressive symptoms.

Objectives: Gender disparities, particularly among young women with cardiovascular disease, are a growing cause for concern. Depression is a prevalent and prognostically important comorbidity in peripheral arterial disease (PAD), but its prevalence has not been described as a function of gender and age. Therefore, we compared depressive symptoms at the time of PAD diagnosis and 6 months later by gender and age in PAD patients.
