Study of the circadian blood pressure profile in patient with arterial hypertension

In arterial hypertension besides reducing blood pressure, we should think about the circadian pressure profile that the patient presents, since the patients non depressors (not descent of arterial pressure during the night with regard to the day) (non-dipper) they associate to a worse cardiovascular prognosis. The purpose of the present study was to determine the circadian pressure profile in patient treated arterial hypertension and never previously treated with antihypertensive medication; and its relationship with the organic damage. They were included in the study to 702 patients with clinical indication for 24 hour ambulatory blood pressure monitoring. The 39% was dipper, 2% extreme dipper, 49.6% non-dipper and 9.4% riser. The patient non dipper had bigger levels of 24 hours systolic blood pressure, night blood pressure and bigger organic damage. The main factors associated to this pattern were the clinic systolic blood pressure, obesity and overalls a filtrate smaller glomerular to 60 ml/min.
