[Restless legs syndrome and cardiovascular risk].

Large epidemiological studies have repeatedly suggested a possible association between restless legs syndrome (RLS) and common cardiovascular diseases and cardiovascular risk factors. Patients complaining of symptoms of RLS were also more likely to suffer from coronary artery disease, stroke, or, in some instances, hypertension. The underlying pathogenesis of the disease association depicted above has not been elucidated conclusively. Increased activation of the sympathetic nervous system - due to the RLS itself and the frequently accompanying periodic limb movements - has been linked to increased cardiovascular stress in patients with RLS.
