Significance of antinuclear antibodies and rheumatoid factor in patients with advanced peripheral arterial disease.

Objective: To determine whether or not elevated titers of antinuclear antibodies (ANA) and/or rheumatoid factor (RF) are associated with patients with advanced peripheral arterial disease (PAD).

Subjects And Methods: A cross-sectional study was done between September 2005 and December 2006. Fifty-eight patients with clinical and angiographic evidence of PAD and 41 controls were studied.

Prevalence of metabolic syndrome in patients with clinically advanced peripheral vascular disease.

The aim of this cross-sectional study was to determine the prevalence of metabolic syndrome (MetS) and its components among 100 patients with progressive peripheral arterial disease (PAD) referred for diagnostic angiography in preparation for a revascularization procedure. The prevalence of MetS was more than 95%. Diabetes mellitus was the most prevalent component followed by hypertension and low high-density lipoprotein.
