Short-term beat-to-beat but not ambulatory blood pressure variability is correlated to carotid intima-media thickness.

Objectives: Several studies have shown that blood pressure (BP) variability derived from ambulatory blood pressure monitoring (ABPM) is associated with target organ damage development. However, the use of discontinuous ABPM to assess rapid BP changes is unavoidably limited by the long frequency at which automated measures are scheduled. The aim of our study was to identify whether ABPM-derived variability or short-term beat-to-beat BP variability is better associated with common carotid artery intima-media thickness (CCA-IMT) in untreated hypertensive patients.

Brain edema formation is associated with the time rate of blood pressure variation in acute stroke patients.

Objectives: Both brain edema and increased blood pressure (BP) variability are associated with poor outcome after stroke. The aim of the present study was to evaluate a possible association between edema formation and a relatively new index of BP variability defined as time rate (TR) of BP variation.

Patients And Methods: A total of 128 first-ever acute stroke patients underwent 24-h ambulatory BP monitoring within 24 h from onset of stroke.

Time rate of blood pressure variation: a new factor associated with coronary atherosclerosis.

Objectives: Previous studies have demonstrated that the time rate of blood pressure (BP) variation was associated with early carotid atherosclerosis, independent of peripheral and central BP levels. We evaluated the association between the rate of BP variation, derived from ambulatory BP monitoring (ABPM) data analysis, and the severity and topography of coronary artery lesion in a cohort of normotensive patients with suspected coronary artery disease.

Methods: ABPM and coronary angiography were performed in 162 normotensive patients with suspected coronary artery disease.

Time rate of blood pressure variation is associated with impaired renal function in hypertensive patients.

Objectives: The rate of blood pressure (BP) variation has been positively associated with intima-media thickness of common carotid arteries and left ventricular mass. We evaluated the association between the rate of BP variation derived from ambulatory blood pressure monitoring (ABPM) data analysis and impaired renal function.

Methods: Twenty-four-hour ABPM was performed in 803 untreated hypertensive patients.

Comparison of noninvasive oscillometric and intra-arterial blood pressure measurements in hyperacute stroke.

Objectives: This study aims to compare automatic oscillometric blood pressure recordings with simultaneous direct intra-arterial blood pressure measurements in hyperacute stroke patients to test the accuracy of oscillometric readings.

Methods: A total of 51 first-ever stroke patients underwent simultaneous noninvasive automatic oscillometric and intra-arterial blood pressure monitoring within 3 h of ictus. Casual blood pressure was measured in both arms using a standard mercury sphygmomanometer on hospital admission.
