Restless Legs Syndrome - RLS and Cardiovascular Disease (en Inglés) - Khosro Hekmat

A hundred pressure spikes in a single night.

Periodic leg movements in sleep raise blood pressure briefly, by 22 millimetres of mercury for selected movements in a small study and by 12 on average across all movements in a larger one. In one night, 89 people with restless legs had on average 788 such rises, measured beat by beat.

Whether heart disease follows from it is not proven. This volume gives the figures on both sides: the odds ratio of 2.07 from the largest cross-sectional study and the hazard ratio of 1.09, with an interval that includes no effect, from the four high-quality longitudinal ones. It also explains why the duration of the illness is a clue worth following, not yet a proven risk factor.

The practical part runs in both directions: what treating the legs means for the heart, and which heart medicines make the legs restless. Along with high blood pressure, stroke, kidneys, veins and pregnancy.
