BACKGROUND: Epidemiological studies demonstrate an inverse association between serum magnesium and incidence of cardiovascular disease. Diuretics commonly cause hypomagneseamia. METHOD: We evaluated effects of magnesium supplementation on blood pressure (BP) and vascular function in thiazide-treated hypertensive women in a randomized, double-blind, clinical trial. Hypertensive women (40-65 years) on hydrochlorothiazide and mean 24-h BP at least 130/80 mmHg were divided into placebo and supplementation (magnesium chelate 600 mg/day) groups...

OBJECTIVE: Increased sympathetic activity is one of the proposed mechanisms underlying exaggerated blood pressure (BP) response to exercise (EBPR). Heart rate recovery (HRR) is a simple non-invasive measurement analyzing autonomic nervous dysfunction, and has been shown to predict cardiovascular disease mortality. We aimed to the association between HRR and EBPR in patients with hypertension according to the circadian pattern and white coat hypertension. DESIGN AND METHOD: A total of 409 consecutive patients who simultaneously underwent Treadmill test and 24-hours ambulatory BP monitoring (ABPM) were included to this cross-sectional case-control study...

Hypertension is a major risk factor for stroke, coronary artery disease and kidney damage in adults and children. There is a paucity of data on the long-term sequelae of persistent hypertension in children, but it is already known that children with hypertension have evidence of end organ damage and are at risk of hypertension into adulthood. The prevalence of hypertension in children is rising, most likely due to a concurrent rise in obesity rates. In children with hypertension, non-pharmacological measures are often recommended as first-line therapy, but a significant proportion of children will eventually require pharmacological treatment to reduce blood pressure, especially those with evidence of end organ damage at presentation or during follow-up...

Heart disease, stroke, and kidney failure are leading causes of death worldwide, and hypertension is a significant risk factor for each. Hypertension is less common in women, compared to men, in those younger than 45 years of age. This trend is reversed in those 65 years and older. In the US between 2011-2014, the prevalence of hypertension in women and men by age group was 6% vs 8% (18-39 years), 30% vs 35% (40-59 years), and 67% vs 63% (60 years and over). Awareness, treatment, and control rates differ between genders with women being more aware of their diagnosis (85% vs 80%), more likely to take their medications (81% vs 71%) and more frequently having controlled hypertension (55% vs 49%)...

It has been confirmed that clinical significance of home blood pressure measurements (HBPM) is higher than clinic BP measurements and ambulatory BP monitoring. However, several drawbacks of HBPM have also been mentioned, e.g. selection and reporting biases, difficulties of calculation of multiple measurements, difficulties of onsite judgement of numerous recordings, etc. Recent devices for HBPM incorporate memory function. This function can overcome such drawbacks of HBPM. These memorized data can transmit, storage, retrieve, be arithmetic and control, be judged based on algorithm and be got feedback...

OBJECTIVE: Blood pressure (BP) control is the most established practice for preventing the progression of chronic kidney disease (CKD). We examined the BP control and nocturnal dipping pattern change in hypertensive patients with CKD and its effects on target organ damages. DESIGN AND METHOD: We recruited 378 hypertensive CKD patients from 4 centers in Korea. They underwent office and ambulatory BP monitoring at the time of enrollment and 1 year after. High office and ambulatory BP was defined as > 140/90 mmHg and > 135/85 mmHg (daytime)/> 120/70 mmHg (nighttime), respectively...

OBJECTIVE: Differences in blood pressure (BP) reading between multiple measurements, known as BP variability, is a strong predictor of cardiovascular and all-cause mortality. Lack of consensus on quantifying and reporting BP variability has limited its use in clinical practice. We aimed to determine the best possible way to quantify BP variability that would improve predictability of long-term mortality among elderly hypertensive population. DESIGN AND METHOD: We used data from a subset of patients (n = 694) aged > 65 years from the Second Australian National Blood Pressure (ANBP2) study...

OBJECTIVE: Both brachial blood pressure (BP) level and its variability (BPV) have significant association with cardiac structure and function. Recent studies indicated that central BP was superior to brachial BP in the association with cardiac abnormities. However, it remains unknown that whether central BPV is better associated with cardiac structure and function. We were, therefore, aimed to investigate and compare central and brachial BPV, in terms of the identification of cardiac abnormities...

OBJECTIVE: Central blood pressure (BP) is suggested to be more closely correlated to target organ damage and cardiovascular events than brachial BP. Outcome-based thresholds for the diagnosis of central hypertension has been recently proposed. However, little is known about central hypertension. In an untreated patient cohort, we therefore investigated the prevalence of central hypertension and its association with target organ damage. DESIGN AND METHOD: Consecutive untreated patients referred for ambulatory BP monitoring to our Hypertension Clinic were recruited...

OBJECTIVE: It has been long believed that there is a close association between hypertension and atrial fibrillation (AF). However, there have been few studies on the impact of antihypertensive medication in hypertensives with AF. To investigate whether the timing of the antihypertensive drug administration influences blood pressure (BP) level and biomarkers to hypertensives with AF. DESIGN AND METHOD: The present study was a multicentered, prospective, randomized, open-labelled clinical trial to investigate the difference in the effect of telmisartan/amlodipine combination tablets on BP levels and BP variability using ambulatory BP monitoring (ABPM) and home BP between the morning administration and the bedtime administration in hypertensives with paroxysmal AF...
