Fourier analysis of circadian blood pressure profile in secondary hypertension

Blood pressure circadian rhythm in essential hypertension.

1. Both systolic and diastolic blood pressure show a well defined circadian variation in ambulatory hypertensive subjects. 2. Blood pressure is highest in the mid-morning (10.00 hours) and lowest during sleep at 03.00 hours. 3. Treatment with oxprenolol (taken during the day) reduces daytime blood pressure but is less effective during the night and early morning.

Variability of circadian blood pressure profile during 24-hour ambulatory blood pressure monitoring in hypertensive patients.

BACKGROUND Evaluation of circadian blood pressure (BP) profile is an important element of ambulatory BP monitoring (ABPM). Abnormal nocturnal fall in BP is more common in patients with secondary causes of hypertension and in the elderly. Cardiovascular risk is substantially increased in these patients. AIM Analysis of circadian BP profile in a population of treated hypertensives and identific...

Chronology of blood pressure changes in renal hypertension induced by solid plexiglass clips in the rat

The objective of this study was to determine the chronology of changes in blood pressure in renalhypertension induced by solid plexiglass clips in rats. Saw blades with the thickness of 0.21-0.22 mm wereused to make clips sized 4 × 2 × 2 mm from a piece of 2-mm thick plexiglass. Rats were subjected to shamoperation or left renal arterial clipping, and 1, 2, 3 and 4 weeks later blood pressure, a...

Effectiveness of Compassion-Focused Therapy on Blood Pressure and Quality of Life in Women with Hypertension

Introduction: Due to the increasing prevalence of patients with hypertension in Iran and the world as well as the adverse impact of this disease on quality of life, there is an urgent need to develop effective and empirically supported psychological interventions in this population. This study aimed to evaluate the effectiveness of compassion-focused therapy on blood pressure and the quality of...
