A SNP upstream of the INSIG2 gene, rs7566605, was recently found to be associated with obesity as measured by body mass index (BMI) by Herbert and colleagues. The association between increased BMI...

Association of ankle-brachial index and plaques in the carotid and femoral arteries with cardiovascular events and total mortality in a population-based study with 13 years of follow-up (2006)

Lamina, Claudia, Meisinger, Christa, Heid, Iris M., Löwel, Hannelore, Rantner, Barbara, Koenig, Wolfgang, ...

Aims Peripheral arterial occlusive disease is associated with a high risk of cardiovascular morbidity and mortality. We prospectively examined the association of the ankle-brachial index (ABI) and...
