We examined the effects of individually adjusted isonatremic and hyponatremic dialysate on intradialytic and interdialytic blood pressure in patients with intradialytic hypertension. <strong>Methods.</strong> We enrolled 11 patients with intradialytic hypertension in a prospective randomized cross-over study, with 4 treatment periods of different dialysate sodium concentrations. Period 1 (run-in) and 3 (wash-out) were standardized at 140 mEq/L;period 2 and 4 with iso- or hyponatremic sodium dialysate. Blood pressure was recorded each dialysis session, and 24-hour ambulatory blood pressure monitoring was performed at the end of each treatment period. <strong>Results.</strong> Isonatremic and hyponatremic dialysate were associated with significantly lower pre- and post-dialysis blood pressure as compared to baseline 140 mEq/L dialysate (predialysis 148.3 ± 24.7/67.7 ± 12.0 and 144.4 ± 16.5/68.8 ± 13.3 vs. 158.0 ± 18.3/75.6 ± 11.4 mmHg, resp p = 0.04 and 0.007 for systolic and p = 0.004 and 0.04 for diastolic blood pressure;postdialysis 154.2 ± 25.5/76.6 ± 14.1 and 142.5 ± 20.7/73.0 ± 12.9 vs. 159.1 ± 21.6/80.3 ± 12.1 mmHg, resp NS and p = 0.01 for systolic and NS and p = 0.04 for diastolic blood pressure). Postdialysis and 24 h systolic blood pressure tended to be lower with hyponatremic compared to isonatremic dialysate. <strong>Conclusion.</strong> Individually tailoring dialysate sodium concentration, based on the sodium set-point of each patient, resulted in a lower pre- and post-dialysis blood pressure in patients with intradialytic hypertension. 24 h blood pressure values tended to be lower as well with hyponatremic dialysate. 展开更多

This article is a review of 25 publications on ambulatory blood pressure monitoring(ABPM) and the importance of its results in everyday clinical practice. These studies, published in 2008-2011, were selected from the Scopus database, but are also available in Pubmed. They were prepared by researchers from around the world, concerned with the problems of proper control of blood pressure(BP), and of abnormalities in the circadian pattern of BP in patients with arterial hypertension, diabetes mellitus or renal failure. In the first part of this article, I analyse publications focused on some nuances in the methodology of ABPM and recommend ways to avoid some traps, related not only to the individual patient but also to the device used and the technical staff. The next section is devoted to the advantages of ABPM as a diagnostic tool which enables clinicians to learn about patients' BP during sleep, and emphasizes the practical implications of this information for so-called chronotherapy. This section also presents some new studies on the prognostic value of ABPM in patients with cardiovascular(CV) risk. Some recent articles on the results of various methods of pharmacological treatment of arterial hypertension in different agegroups are then described. The observations presented in this article may be helpful not only for researchers interested in the chronobiology of the CV system, but also for general practitioners using ABPM. 展开更多

Management of hypertension (HTN) largely relies on proper and accurate measurement of blood pressure (BP). Even following the criteria for HTN diagnosis defined in the Fourth report on high BP in children and adolescents, inaccurate diagnosis and misdiagnosis can occur with white coat effect and masked HTN. The use of Ambulatory Blood Pressure Monitoring (ABPM) has been increasing in pediatrics in the last 20 years. The main use of ABPM is to differentiate between sustained HTN and white coat HTN in patients who have elevated casual BP measurements and to detect masked HTN in high risk patients. ABPM is most useful in patients with casual BP within 20% of the 95th percentile for age, gender, and height. This report will highlight the use of ABPM in the evaluation of elevated BP and management of HTN in pediatrics. The discussion includes a review of various non-invasive BP measuring techniques, a description of ABPM and ABPM-unique data and diagnoses, updated ABPM clinical data more specific to pediatrics, its use in HTN clinical trials, and future outlook and direction of ABPM in pediatrics. 展开更多

Objective To study the pattern of circadian blood pressure changes in patients with se-condary hypertension. Methods The 24h ambulatory blood pressure monitoring was performed in 80 patients with secondary hypertension (SH) including primary aldosteronism in 44, pheochromocytoma in 11, renovas-cular hypertension in 10, renoparenchymal hypertension in 15 and compared with 80 patients with essential hy-pertension (EH) matched by age and sex. Results The diurnal rhythm in patients with SH was different from that of patients with EU. The diurnal curves in SU and EU was overlapped in daytime and separated from each other at nighttime. The nocturnal blood pressure fall was less and average blood pressure at nighttime was higher in patients with SH than those in patients with Eli (P <0. 01). The nighttime blood pressure loading and non-dipper phenomenon were much more frequently seen in patients with SH than those in patients with Eli (P <0. 01). The nighttime blood pressure/daytime blood pressure ratio was significantly higher in patients with SH than that in patients with Eli (P <0. 01).

Ambulatory blood pressure monitoring(ABPM)has become indispensable in the current management of hypertension.ABPM is particularly useful in the accurate diagnosis of hypertension.Its diagnostic thresholds had been recently established based on hard clinical outcomes.Cross-classification of patients according to office and ambulatory blood pressure identifies white-coat,masked,and sustained hypertension.ABPM is also useful in cardiovascular(CV)risk assessment.It provides information on daytime and nighttime blood pressure and circadian rhythm,particularly nighttime blood pressure dipping.Nighttime blood pressure is predictive of CV risk independent of office and daytime blood pressure.Isolated nocturnal hypertension is a special form of masked hypertension,with normal daytime but elevated nocturnal blood pressure.It also helps in the evaluation of blood pressure fluctuation and variation,such as morning blood pressure surge and reading-to-reading blood pressure variability.ABPM may derive several other indexes,such as ambulatory blood pressure index and salt sensitivity index,which may be useful in CV evaluations. 展开更多

Background:Although multiple measures of blood pressure variability(BPV)have been proposed,whether they are better than mean blood pressure in predicting target organs is unclear.We aimed to determine the relationship between short term BPV and target organ injury.Methods:This study was a retrospective study,and 635 inpatients in the Department of Cardiology from 2015 to 2020 were selected.We divided participants into four groups on the basis of the quartiles of BPV.One-way analysis of variance was used to compare the differences between the groups,and linear regression was used to analyze the relationship between BPV and target organ damage.Results:The average age of 635 patients was 74.36±6.50 years old.Among them,354 of 627 patients had diminished renal function(56.5%),221of 604 patients had associated left ventricular hypertrophy(36.6%),and 227 of 231 patients had carotid plaque formation(98.3%).The baseline data indicated significant differences in fasting glucose,total cholesterol,low-density lipoprotein,creatinine,glomerular filtration rate,sex,calcium channel blocker use,and the rate of diminished renal function.Multiple linear regression analysis showed that BPV was negatively correlated with renal injury(creatinine:r=0.306,p<0.01;estimated glomerular filtration rate:r=0.058,p<0.01),and BPV is positively correlated with cardiac injury(r=0.083,p<0.01).Elevated BPV was not found to be associated with vascularinjury.Conclusion:Renal function decreases with increasing BPV and left ventricular mass increases with increasing BPV. 展开更多

Background Fall injuries are common among the elderly. The aim of this study was to investigate whether blood-pressure patterns, as measured by 24-h ambulatory blood pressure monitoring (ABPM), or intensification of antihypertensive therapy following the 24-h ABPM, may be associated with fall injuries in hypertensive elderly patients. Methods In a retrospective study, community-based elderly patients (age ≥ 70 years) who were referred to 24-h ABPM were evaluated for fall injuries within one-year post-ABPM. We compared the clinical characteristics, 24-h ABPM patterns and the intensification of hypertensive therapy following 24-h ABPM, between patients with and without a fall injury. Results Overall 1032 hypertensive elderly patients were evaluated. Fifty-five (5.3%) had a fall injury episode in the year following ABPM. Patients with a fall injury were significantly older, and with higher rates of previous falls. Lower 24-h diastolic blood-pressure (67.3 ± 7.6 vs. 70.7 ± 8.8 mmHg; P 〈 0.005) and increased pulse-pressure (74.7 ± 14.3 vs. 68.3 ± 13.7 mmHg; P 〈 0.005), were found in the patients with a fall injury, compared to those without a fall injury. After adjustment for age, gender, diabetes mellitus and previous falls, lower diastolic blood-pressure and increased pulse-pressure were independent predictors of fall injury. Intensification of antihypertensive treatment following the 24-h ABPM was not associated with an increased rate of fall injury. Conclusions Low diastolic blood-pressure and increased pulse-pressure in 24-h ABPM were associated with an increased risk of fall injury in elderly hypertensive patients. Intensification of antihypertensive treatment following 24-h ABPM was not associated with an increased risk of fall injury. 展开更多

Objective The aim of this study was to investigate the relationship between peripheral plasma stem cell factor (SCF)/c-kit levels and the types of dipper and non-dipper hypertension in hypertensive patients.Methods This cross-sectional study included newly diagnosed hypertensive patients who underwent 24-hour ambulatory blood pressure monitor (ABPM) between January 2009 and 2012 in Jiangning city. Patients were divided into the dipper group and the non-dipper group according to ABPM measurements. The levels of SCF and its receptor c-kit, tumor necrosis factor-α (TNF-α) and interleukin 6 (IL-6) in peripheral blood were measured via enzyme-linked immunosorbent assays. The serum levels of glucose and lipid were examined as well. The levels of SCF/c-kit were compared between the dippers and the non-dippers; and their correlation with 24-hour mean systolic blood pressure (MSBP), 24-hour mean diastolic blood pressure (MDBP), TNF-αand IL-6 were investigated using linear regression analyses statistically.Results A total of 247 patients with newly diagnosed hypertension were recruited into the study, including 116 non-dippers and 131 dippers. The levels of peripheral plasma SCF were higher in non-dipper group (907.1±52.7 ng/L vs. 778.7±44.6 ng/L; t=2.837, P<0.01), and the levels of c-kit were higher in non-dipper group too (13.2±1.7 μg/L vs 9.57±1.4 μg/L; t=2.831, P<0.01). Linear regression analysis revealed that SCF/ckit levels were significantly positively correlated with MSBP, MDBP, plasma TNF-α, and IL-6 levels (all P<0.01).Conclusions Peripheral plasma SCF/c-kit levels are higher in patients with non-dipper hypertension than those with dipper one, and significantly correlate with 24-hour MSBP, 24-hour MDBP, serum TNF-α and IL-6 levels. 展开更多

It is essential to know if they have proper control of hypertension. The aim of this study was to identify the associated factors to masked uncon- trolled hypertension and false uncontrolled hypertension in older patients. Methods Two-hundred seventy-three individuals (70.1±6.7 years-old) had blood pressure (BP) measured at the office and by ambulatory BP monitoring (ABPM), with the definition of controlled group (C), individuals with high office BP and adequate ABPM, called white-coat effect group (WCE), uncontrolled (UC), and subjects with ap- propriate office BP and elevated ABPM denominated masked effect group (ME). Age, body mass index, diabetes, pulse pressure (PP) and BP dipping during sleep were evaluated (Kruskal-Wallis test and logistic regression models). Results Age was higher in UC than in C and ME (P 〈 0.01), and 24-h ABPM PP was lower in C (48± 7 mmHg) and WCE (51±6 mmHg) than in UC (67±12 mmHg) and ME (59±8 mmHg) (P 〈 0.01). Sleep systolic BP dipping was lower in ME than in C (P = 0.03). Female gender was associated with a greater chance of being of ME group, which showed a higher PP and lower BP dipping during sleep. Conclusions In older individuals, office BP measure- ments did not allow the detection of associated factors that would permit to differentiate WCE from UC group and C from ME group. ABPM favored the identification of a higher PP and a lower BP dipping during sleep in the masked effect and uncontrolled groups. 展开更多

Essential hypertension is a difficult diagnosis in children and the gene of the renal-epithelial chloride channel ClC-Kb is potentially predisposing. In vitro studies have shown that a common ClC-Kb threonine481serine (T481S) polymorphism leads to enhanced chloride channel activity and may predispose for hypertension (HT). We therefore analysed children at risk for HT for the T481S polymorphism and associated genotype with blood pressure (BP) status. A total of 48 children with essential hypertension (mean age 14.4 &#177;2.7 years, 26 male;22 female;mean BP 143.4 &#177;7.5/88 &#177;5.8 mmHg) were compared with 78 children with white-coat HT (WCHT), who showed occasionally hypertensive BP values, which were not confirmed by ambulatory blood pressure monitoring (mean age 13.7 &#177;2.5 years, 49 male, 29 female;mean BP 122.4 &#177;4.3/68.2 &#177;3.5 mmHg). Other causes of HT were excluded. Allelic frequencies of hypertensive patients were not significantly different from those with WCHT (HT: A 0.84;T 0.16 vs. WCHT: A 0.85;T 0.15). However, the T-allele was observed more frequently in WCHT subjects with systolic and diastolic BP exceeding the 90th percentile (A 0.71;T 0.29, n = 34, p 【0.05, considered as borderline hypertensive). The preliminary data suggest that children with WCHT carry the ClC-Kb T481S polymorphism more often and that this variant may predispose for development of arterial HT. 展开更多

Objective:Abnormal circadian blood pressure rhythm has been revealed to be associated with hypertensive target organ damage and cardiovascular events,but its association with readmission risk in patients with heart failure with preserved ejection fraction(HFpEF)remains unknown.We conducted a retrospective study to explore the relationship between circadian blood pressure rhythm and readmission risk in HFpEF patients.Methods:We retrospectively collected baseline and follow-up data on HFpEF patients who underwent ambulatory blood pressure monitoring(ABPM)from May 2015 to October 2019.Patient circadian blood pressure rhythms defi ned by ABPM were grouped as dipper,nondipper,or riser patterns.Univariate and multivariate linear regression analyses were performed to assess the association between circadian blood pressure rhythm and readmission risk.Results:A total of 122 patients were enrolled in this study.The mean age and ejection fraction were 69.87 years and 61.44%,respectively,with mean the N-terminal pro-B-type natriuretic peptide(NT-proBNP)level being 1048.15 pg/mL.There were signifi cant differences in the 24-hour systolic blood pressure(SBP),sleep SBP,and sleep diastolic blood pressure(DBP)among the three groups,where the 24-hour SBP,sleep SBP,and sleep DBP in the riser pattern group were markedly higher than in the dipper pattern group.Notably,serum NT-proBNP levels,the proportion of patients readmitted for heart failure and the mean number of admissions differed markedly among three groups.Instructively,multivariate linear regression analysis showed that the riser pattern was a signifi cant and independent risk factor for increased serum NT-proBNP level(β=929.16,95%confi dence interval 178.79–1679.53,P=0.016).In multivariate logistic regression analysis,the riser pattern was demonstrated to be a signifi cant risk factor for readmission(odds ratio 11.23,95%confi dence interval 2.01–62.67,P=0.006)in HFpEF patients.Conclusion:The riser blood pressure pattern is a potential risk factor for elevated serum NT-proBNP level and readmission in HFpEF patients. 展开更多
