Association of home and ambulatory blood pressure variability with left ventricular mass index in chronic kidney disease patients.

Increased blood pressure (BP) variability is associated with the development of target organ damage. However, the optimal type and index of BP variability (BPV) regarding their prognostic significance is unclear. The aim of our study was to compare the association of ambulatory and home BPV with the left ventricular mass index (LVMI) in patients with chronic kidney disease (CKD).

Hypertension: An immune related disorder?

Hypertension is a multifactorial disorder with serious complications and unknown etiology. Among potential contributors, immune dysregulation has been also proposed. The study population included 61 consecutive hypertensive patients and 55 healthy individuals of similar age and sex distribution.

A functional supervised learning approach to the study of blood pressure data.

In this work, a functional supervised learning scheme is proposed for the classification of subjects into normotensive and hypertensive groups, using solely the 24-hour blood pressure data, relying on the concepts of Fréchet mean and Fréchet variance for appropriate deformable functional models for the blood pressure data. The schemes are trained on real clinical data, and their performance was assessed and found to be very satisfactory.

Association of Ambulatory Blood Pressure Monitoring parameters with the Framingham Stroke Risk Profile.

The Framingham Stroke Risk Profile (FSRP) is a novel and reliable tool for estimating the 10-year probability for incident stroke in stroke-free individuals, while the predictive value of ambulatory blood pressure monitoring (ABPM) for first-ever and recurrent stroke has been well established. We sought to evaluate cross-sectionally the association of ABPM parameters with FSRP score in a large sample of 2343 consecutive stroke-free individuals (mean age: 56.0±12.

Differential associations of systolic and diastolic time rate of blood pressure variation with carotid atherosclerosis and plaque echogenicity.

In the current study, the authors sought to assess whether the time rate of systolic and diastolic blood pressure variation is associated with advanced subclinical stages of carotid atherosclerosis and plaque echogenicity assessed by gray scale median. The authors recruited 237 consecutive patients with normotension and hypertension who underwent 24-hour ambulatory blood pressure monitoring and carotid artery ultrasonography. There was an independent association between low 24-hour systolic time rate and increased echogenicity of carotid plaques (adjusted odds ratio for highest vs lower tertiles of gray scale median, 0.
