Current guidelines suggest the use of home blood pressure monitoring (HBPM) as a method complementary to ambulatory blood pressure monitoring (ABPM) for the identification of arterial hypertension. A cross-sectional study was conducted to evaluate the accuracy of a short HBPM schedule compared with ABPM, and to evaluate to what extent HBPM can replace ABPM. A total of 310 patients who performed ABPM in our hypertension clinic were enrolled between November 2011 and June 2015. They performed a 4-day HBPM schedule, with two readings in the morning and two readings at night...

Recently, it has been proposed, that the blood pressure (BP) lowering effect of gastric bypass surgery not only is explained by the obtained weight loss, but that the anatomical rearrangement of the gut after 'malabsorptive' surgical techniques, such as the laparoscopic Roux-en-Y gastric bypass (LRYGB), may affect BP through a change in a putative 'entero-renal' axis. If so one could anticipate a reduction in BP even before a noticeable weight loss was obtained. The purpose of the present study was to investigate the very early BP response to LRYGB surgery...

The incidence of cardiovascular disease and mortality rates are high among patients with left ventricular hypertrophy (LVH). Obstructive sleep apnea (OSA) has been reported to increase left ventricular mass (LVM) and cause LVH. The prevalence of hypertension, a major cause of increased LVM, is high in OSA; however, it is still unknown whether OSA is an independent factor that increases LVM in addition to triggering LVH. This study investigated out-of-office blood pressure (BP) via ambulatory BP monitoring (ABPM) in patients with OSA diagnosed by polysomnography (PSG) and sought to determine the effects of OSA and hypertension on LVM...

Objective Hypertension and diurnal blood pressure (BP) variation are widely accepted as risk factors for renal damage. However, the effects of unilateral nephrectomy on BP and its circadian rhythm have not yet been clarified in patients with a compromised renal function, including dialysis patients. Methods We investigated 22 unilateral nephrectomized patients (16 men and 6 women, age: 64.5±14.3 years). The function of the circulating renin-angiotensin system (RAS) (plasma renin activity and plasma angiotensin II) and 24-h ambulatory BP monitoring (ABPM) were evaluated before and after nephrectomy...

Ambulatory blood pressure monitoring (ABPM) can assess out-of-clinic blood pressure. ABPM is an underutilized resource in low-income and middle-income countries but should be considered a complementary strategy to clinic blood pressure measurement for the diagnosis and management of hypertension. Potential uses for ABPM in low-income and middle-income countries include screening of high-risk individuals who have concurrent communicable diseases, such as HIV, and in task-shifting health care strategies.

BACKGROUND: Risk assessment is of particular importance for patients undergoing surgical interventions. Orthopedic procedures, especially total joint alloplasty are major procedure associated with high perioperative risk, as well as one of the highest rates of complications. The aim of the present study was to establish the prevalence of classical and non-classical cardiovascular risk factors in patients undergoing total hip or knee alloplasty. METHODS: The CRASH-JOINT (Cardiovascular Risk Assessment ScHeme in JOINT alloplasty) was a prospective, epidemiological study performed in consecutive patients scheduled for total joint (hip or knee) replacement surgery...

Blood pressure (BP) monitors rely on pulse detection. Some blood pressure monitors use pulse timings to analyse pulse interval variability for arrhythmia screening, but this assumes that the pulse interval timings detected from BP cuffs are accurate compared with RR intervals derived from ECG. In this study we compared the accuracy of pulse intervals detected using an ambulatory blood pressure monitor (ABPM) with single lead ECG. Twenty participants wore an ABPM for three hours and a data logger which synchronously measured cuff pressure and ECG...

Hypertension, a major risk factor for heart disease and stroke, is the world's leading cause of preventable, premature death. A common polymorphism (677C→T) in the gene encoding the folate metabolizing enzyme methylenetetrahydrofolate reductase (MTHFR) is associated with increased blood pressure, and there is accumulating evidence demonstrating that this phenotype can be modulated, specifically in individuals with the MTHFR 677TT genotype, by the B-vitamin riboflavin, an essential co-factor for MTHFR. The underlying mechanism that links this polymorphism, and the related gene-nutrient interaction, with hypertension is currently unknown...

REVIEW

Masked hypertension, which is present when in-office normotension translates to out-of-office hypertension, is present in a surprisingly high percentage of untreated persons and an even higher percentage of patients after beginning antihypertensive medication. Not only are persons with prehypertension more likely to have masked hypertension than those with optimal blood pressure (BP), but also they frequently develop target organ damage prior to transitioning to sustained hypertension. Furthermore, the frequency of masked hypertension is high in individuals of African inheritance and in the presence of increased cardiovascular risk factors and disease states, such as diabetes and chronic renal failure...

BACKGROUND: Uncontrolled resistant hypertension (RH) defined by the mean 24-hour ambulatory blood pressure (ABPM) represents an independent risk factor in hypertensive patients. Predictors of blood pressure (BP) control in RH are not yet clearly defined. OBJECTIVES: To evaluate the predictors of BP control in RH patients with repeated ABPM measurements. METHODS: 114 consecutive patients from outpatient cardiology office fulfilling criteria for RH (office BP ≥ 140 and/or 90 mmHg, with treatment of ≥ 3 antihypertensive drugs, including diuretic, or controlled BP with > 3 drugs), with two consecutive ABPM studies were compared in clinical characteristics according to BP control assessed by ABPM RESULTS: After the second ABPM, BP was controlled in 25...

INTRODUCTION: The diagnosis and management of hypertension depends on accurate measurement of blood pressure (BP) in order to target antihypertensive treatment appropriately. Most BP measurements take place in a clinic setting, but it has long been recognised that readings taken out-of-office (via home or ambulatory monitoring) estimate true underlying BP more accurately. Recent studies have shown that the change in clinic BP over multiple readings is a significant predictor of the difference between clinic and out-of-office BP...

OBJECTIVE: We have previously noted morning/late-morning hypotension (M/LM) in some hypertensive subjects. Here we intended to establish its prevalence in relation to daytime blood pressure (BP) in general. DESIGN AND METHOD: Daytime hypotension was defined as systolic BP<110mmHg or ≥25% lower than the mean 3 first awake recordings provided that it was also < 85% of the mean 24 h systolic-BP. We evaluated 781 ABPM (Spacelabs 90207/902017A) recordings from 179 subjects with normal BP and 602 hypertensive subjects...
