Background and aimRecently, the European Society of Cardiology task force released a Consensus document (ESC-CD) on pediatric hypertension (HTN) supporting the use of normative tables (age range 6–16 years) for the diagnosis of HTN, while the Hypertension Canada Guidelines (HTN-CGs) proposed static cutoffs. We aimed to assess the prevalence of HTN by ESC-CD or HTN-CGs and their association with glomerular function and left ventricular (LV) geometry in youths with overweight/obesity (OW/OB).Methods and resultsData of 3446 youths were analyzed. HTN by was defined using normative tables (ESC-CD) or static cutoffs of BP ≥ 120/80 in children (age <12 years) and ≥130/85 mmHg in adolescents (age ≥12 years) (HTN-CGs). Mildly reduced glomerular filtration rate was defined by GFR <90 ≥ 60 mL/min/1.73 m2. Concentric LV hypertrophy (cLVH) was assessed in 500 youths and defined by LVH and high relative wall thickness as proposed by ESC-CD. Prevalence of HTN was 27.9% by ESC-CD and 22.7% by HTN-CGs. The association with mildly reduced glomerular filtration rate was significant only in hypertensive adolescents classified by HTN-CGs [Odds Ratio (OR), 95%Cl] 2.16 (1.44–3.24), whereas the association with cLVH was significant using both criteria: children OR 2.18 (1.29–3.67) by ESC-CD and 2.27 (1.32–3.89) by HTN-CGs; adolescents OR 2.62 (1.17–5.84) by ESC-CD and 2.83 (1.14–7.02) by HTN-CGs.ConclusionAlthough static cutoffs may represent a simplification for HTN identification, tables by ESC-CD detect a higher number of hypertensive youths before a clear appearance of glomerular impairment, which offers advantages in terms of primary cardiovascular prevention. 相似文献

AimTo assess a new formula to improve the screening of isolated impaired glucose tolerance (IGT) in youth with overweight/obesity (OW/OB).Methods and resultsA cross-sectional study was performed in 1189 Caucasian youths with OW/OB aged 5–17 years, in whom impaired fasting glucose and high glycosylated hemoglobin were excluded. The sample was divided into training set (TS) (n = 883) and validation set (VS) (n = 306). Fasting (FG) and post-load plasma glucose, alanine aminotransferase (ALT), lipids and familial history for type 2 diabetes (FD) were available in all individuals. In the TS youths with IGT (n = 58, 7.0%) showed higher prevalence of female sex (FS), FD, and higher levels of FG, post-load glucose, ALT and lower levels of HDL-cholesterol vs individuals without IGT. The linear formula was obtained by logistic regression analysis in the TS: 0.051ALT + 0.071FG + 0.871FD + (0.061HDL1 ? 1) + 11FS. The best cut-off was 5.84. The performance of the formula vs IGT was: sensitivity: 0.74 and specificity: 0.71. Similar results were obtained in the VS.ConclusionsUsing metabolic and anamnestic data we obtained a simple formula with a good performance for screening isolated IGT. This formula may support pediatricians to identify youths with OW/OB in whom the OGTT may be useful for detecting IGT. 相似文献

ObjectivesThis study sought to assess the respective effects of aldosterone and blood pressure (BP) levels on myocardial fibrosis in humans.BackgroundExperimentally, aldosterone promotes left ventricular (LV) hypertrophy, and interstitial myocardial fibrosis in the presence of high salt intake.MethodsThe study included 20 patients with primary aldosteronism (PA) (high aldosterone and high BP), 20 patients with essential hypertension (HTN) (average aldosterone and high BP), 20 patients with secondary aldosteronism due to Bartter/Gitelman (BG) syndrome (high aldosterone and normal BP), and 20 healthy subjects (HS) (normal aldosterone and normal BP). Participants in each group were of similar age and sex distributions, and asymptomatic. Cardiac magnetic resonance including cine and T1 mapping was performed blind to the study group to quantify global LV mass index, as well as intracellular mass index and extracellular mass index considered as a measure of myocardial fibrosis in vivo.ResultsMedian plasma aldosterone concentration was as follows: PA = 709 pmol/l (interquartile range [IQR]: 430 to 918 pmol/l); HTN = 197 pmol/l (IQR: 121 to 345 pmol/l); BG = 297 pmol/l (IQR: 180 to 428 pmol/l); and HS = 105 pmol/l (IQR: 85 to 227 pmol/l). Systolic BP was as follows: PA = 147 ± 15 mm Hg; HTN = 133 ± 19 mm Hg; BG = 116 ± 9 mm Hg; and HS = 117 ± 12 mm Hg. LV end-diastolic volume showed underloading in BG and overloading in patients with PA (63 ± 13 ml/m2 vs. 82 ± 15 ml/m2; p < 0.0001). Intracellular mass index increased with BP across groups (BG: 36 [IQR: 29 to 41]; HS: 40 [IQR: 36 to 46]; HTN: 51 [IQR: 42 to 54]; PA: 50 [IQR: 46 to 67]; p < 0.0001). Extracellular mass index was similar in BG, HS, and HTN (16 [IQR: 12 to 20]; 15 [IQR: 11 to 18]; and 14 [IQR: 12 to 17], respectively) but 30% higher in PA (21 [IQR: 18 to 29]; p < 0.0001) remaining significant after adjustment for mean BP.ConclusionsOnly primary pathological aldosterone excess combined with high BP increased both extracellular myocardial matrix and intracellular mass. Secondary aldosterone excess with normal BP did not affect extracellular myocardial matrix. (Study of Myocardial Interstitial Fibrosis in Hyperaldosteronism; NCT02938910). 相似文献

Background and aimsChildhood overweight and obesity are lifetime risk factors for cardiovascular disease but the relationship between dynamic body mass index (BMI) change and cardiovascular structure and function in early childhood remains unclear.Methods and resultsThis cohort study consisted 525 participants with 6 distinct representative growth patterns to examine the associations between BMI growth patterns and subsequent cardiovascular structure and function at age 4. BMIs were obtained at birth, 2 and 4 years old. Cardiovascular assessments were performed, including blood pressure (BP), cardiac geometric parameters, left ventricular (LV) function, speckle-tracking, integrated backscatter analysis and carotid intima-media thickness. Compared to the stable normal BMI pattern, children with the stable overweight (OW) pattern had significantly greater LV anatomic parameters in fully adjusted models. Children with the catch-up (CU) pattern revealed a uniform trend and had poorer strain. LV diameters and integrated backscatter signals were larger for those with BMI gain and lose pattern. Children with BMI lose pattern showed improved tendency involving LV mass index and BP. Both OW and CU patterns were associated with high systolic BP [odds ratio (95% CI): OW: 3.67 (1.08, 12.47); CU: 4.24 (1.75, 10.28)]. Compared to static BMI measurements at birth, 2 and 4 years old, dynamic BMI growth patterns were more predictive of cardiovascular structure and function at 4.ConclusionsChildren with overweight-related BMI growth patterns in early childhood experienced undesirable cardiovascular functional or structural changes as early as 4 years old, indicating that early intervention is needed and potentially beneficial. 相似文献

Background and aimsHypertension (HTN) is a chronic non-communicable disease influenced by non-modifiable risk factors, such as sex and age, as well as modifiable risk factors such as lifestyle, including diet and smoking. Moreover, diet quality among smokers is worse than that of non-smokers, mainly in terms of antioxidant content. Thus, the current study aimed to investigate whether dietary total antioxidant capacity (dTAC) influences the association between smoking and HTN.Methods and resultsThis cross-sectional study included 4303 graduates (69.35% women) from the Cohort of Minas Gerais Universities (CUME) project. An online food frequency questionnaire was administered to participants, and dTAC was estimated using the ferric reducing antioxidant power method. In the questionnaires, individuals reported smoking status, systolic and diastolic blood pressure values, previous HTN diagnosis, and use of antihypertensive drugs. Logistic regression models were used to estimate the odds ratio and 95% confidence interval between smoking and HTN, stratified by the median dTAC. Current and former smokers had higher dTAC values despite their lower fruit intake. Moreover, coffee was the main contributor to dTAC among them. Smoking was associated with a higher likelihood of HTN, mainly among individuals with a higher dTAC. However, after exclusion of coffee antioxidant capacity, there was an association between only smoking and HTN in individuals with lower dTAC.ConclusionsThe controversial association between higher dTAC and HTN can result from high coffee intake. Higher dTAC without coffee intake may mitigate the association between smoking and HTN in this population. 相似文献

BackgroundLarge blood pressure (BP) variability may contribute to stroke and dementia, but the mechanisms are largely unknown.ObjectivesThis study investigated the association of BP variation, considering its magnitude and direction, with the presence and progression of subclinical brain disease in the general population.MethodsThis study included 2,348 participants age ≥55 years from a prospective cohort study. BP was measured at each visit every 3 to 4 years from 1990 onward. Brain magnetic resonance imaging (MRI) was performed at all visits from 2005 onward. The authors primarily assessed variation as the absolute difference in BP divided by the mean over 2 sequential visits for both systolic BP (SBP) and diastolic BP (DBP), and further assessed the direction of the variation. The authors investigated the multivariate-adjusted associations of BP variation with subsequent measurements of MRI markers of cerebral small vessel disease, brain tissue volumes, and white matter microstructural integrity. Longitudinal changes in these markers also were assessed.ResultsA large SBP variation (top vs. bottom tertiles), measured on average 7 years preceding brain MRI, was associated with higher odds of having severe white matter hyperintensities (WMH) (odds ratio [OR]: 1.32; 95% confidence interval [CI]: 1.21 to 1.43), lacunes (OR: 1.25; 95% CI: 1.04 to 1.48), and microbleeds (OR: 1.16; 95% CI: 1.03 to 1.31). Similarly, this variation was associated with smaller total brain volume and worse white matter microstructural integrity (all p < 0.001). A large SBP variation was also associated with the progression of WMH (rate ratio [RR]: 1.14; 95% CI: 1.02 to 1.27). Higher burdens of these brain imaging markers were observed with both large rises and falls in SBP. Similar findings were observed for DBP variation.ConclusionsElevated BP variation was associated with a wide range of subclinical brain structural changes, including MRI markers of cerebral small vessel disease, smaller brain tissue volumes, and worse white matter microstructural integrity. These subclinical brain changes could be the underlying mechanisms linking BP variation to dementia and stroke. 相似文献

Background and aimTo compare cardiometabolic risk profile and preclinical signs of target organ damage in youth with normal and elevated blood pressure (BP), according to the American Academy of Pediatrics (AAP) guidelines.Methods and resultsThis cross-sectional multicenter study included 2739 youth (5-17 year-old; 170 normal-weight, 610 overweight and 1959 with obesity) defined non hypertensive by the AAP guidelines. Anthropometric, biochemical and liver ultrasound data were available in the whole population; carotid artery ultrasound and echocardiographic assessments were available respectively in 427 and 264 youth. Elevated BP was defined as BP ≥ 90th to <95th percentile for age, gender and height in children or BP ≥ 120/80 to <130/80 in adolescents. The overall prevalence of elevated BP was 18.3%, and significantly increased from normal-weight to obese youth. Young people with elevated BP showed higher levels of body mass index (BMI), insulin resistance and a higher prevalence of liver steatosis (45% vs 36%, p < 0.0001) than normotensive youth, whilst they did not differ for the other cardiometabolic risk factors, neither for carotid intima media thickness or left ventricular mass. Compared with normotensive youth, individuals with elevated BP had an odds ratio (95%Cl) of 3.60 (2.00–6.46) for overweight/obesity, 1.46 (1.19–1.78) for insulin-resistance and 1.45 (1.19–1.77) for liver steatosis, controlling for centers, age and prepubertal stage. The odds for insulin resistance and liver steatosis persisted elevated after correction for BMI-SDS.ConclusionCompared to normotensive youth, elevated BP is associated with increased BMI, insulin resistance and liver steatosis, without significant target organ damage. 相似文献

BackgroundDiurnal variation of natriuretic peptide (NP) levels and its relationship with 24-h blood pressure (BP) rhythm has not been established. Obese individuals have a relative NP deficiency and disturbed BP rhythmicity.ObjectivesThis clinical trial evaluated the diurnal rhythmicity of NPs (B-type natriuretic peptide [BNP], mid-regional pro-atrial natriuretic peptide [MR-proANP], N-terminal pro–B-type natriuretic peptide [NT-proBNP]) and the relationship of NP rhythm with 24-h BP rhythm in healthy lean and obese individuals.MethodsOn the background of a standardized diet, healthy, normotensive, lean (body mass index 18.5 to 25 kg/m2) and obese (body mass index 30 to 45 kg/m2) individuals, age 18 to 40 years, underwent 24-h inpatient protocol involving ambulatory BP monitoring starting 24 h prior to the visit, controlled light intensity, and repeated blood draws for assessment of analytes. Cosinor analysis of normalized NP levels (normalized to 24-h mean value) was conducted to assess the diurnal NP rhythm and its relationship with systolic BP.ResultsAmong 52 participants screened, 40 participants (18 lean, 22 obese; 50% women; 65% Black) completed the study. The median range spread (percentage difference between the minimum and maximum values) over 24 h for MR-proANP, BNP, and NT-proBNP levels was 72.0% (interquartile range [IQR]: 50.9% to 119.6%), 75.5% (IQR: 50.7% to 106.8%), and 135.0% (IQR: 66.3% to 270.4%), respectively. A cosine wave-shaped 24-h oscillation of normalized NP levels (BNP, MR-proANP, and NT-proBNP) was noted both in lean and obese individuals (prhythmicity <0.05 for all). A larger phase difference between MR-proANP BP rhythm (?4.9 h vs. ?0.7 h) and BNP BP rhythm (?3.3 h vs. ?0.9 h) was seen in obese compared with lean individuals.ConclusionsThis human physiological trial elucidates evidence of diurnal NP rhythmicity and the presence of an NP-BP rhythm axis. There exists a misalignment of the NP-BP diurnal rhythm in the obese, which may contribute to the disturbed diurnal BP pattern observed among obese individuals.

ObjectivesThe aim of this multicenter, open-label trial was to evaluate the safety and efficacy of alcohol-mediated renal denervation using a novel catheter system (the Peregrine System Infusion Catheter) for the infusion of dehydrated alcohol as a neurolytic agent into the renal periarterial space.BackgroundThe number of hypertensive patients with uncontrolled blood pressure (BP) remains unacceptably high. The renal sympathetic nervous system has been identified as an attractive therapeutic target.MethodsForty-five patients with uncontrolled hypertension on ≥3 antihypertensive medications underwent bilateral renal denervation using the Peregrine Catheter with 0.6 ml alcohol infused per renal artery.ResultsAll patients were treated as intended. Mean 24-h ambulatory BP reduction at 6 months versus baseline was −11 mm Hg (95% confidence interval [CI]: −15 to −7 mm Hg) for systolic BP and −7 mm Hg (95% CI: −9 to −4 mm Hg) for diastolic BP (p < 0.001 for both). Office systolic BP was reduced by −18/−10 mm Hg (95% CI: −25 to −12/−13 to −6 mm Hg) at 6 months. Antihypertensive medications were reduced in 23% and increased in 5% of patients at 6 months. Adherence to the antihypertensive regimen remained stable over time. The primary safety endpoint, defined as the absence of periprocedural major vascular complications, major bleeding, acute kidney injury, or death within 1 month, was met in 96% of patients (95% CI: 85% to 99%). Two patients had major adverse events of periprocedural access-site pseudoaneurysms, with major bleeding in one. There were no deaths or instances of myocardial infarction, stroke, transient ischemic attack, or renal artery stenosis. Transient microleaks were noted in 42% and 49% of the left and right main renal arteries, respectively. There were 2 cases of minor vessel dissection that resolved without treatment.ConclusionsPrimary results from this trial suggest that alcohol-mediated renal denervation using the Peregrine Catheter safely reduces blood pressure and as such may represent a novel approach for the treatment of hypertension. 相似文献

BackgroundTobacco consumption is considered as one of the major risk factors for cardiovascular (CV) morbidity. However, the effect of paan masala tobacco (PMT) (a type of smokeless tobacco) consumption has not been well studied in our context. Our study is aimed to find an association of CV risk factors between PMT users and nonusers and to correlate those parameters with urinary cotinine level, a degradation product of nicotine occurring in tobacco.MethodsThis comparative cross-sectional study was carried out among 200 participants. The effect of PMT use on CV risk factors such as blood pressure (BP), lipid profile, and body mass index was measured against urine cotinine level. Statistical tests used were χ2 test for categorical variable, independent t-test, Mann–Whitney U test, and Spearman's correlation applied for numerical variable, and multivariate regression analysis was performed as required. The level of significance was set at p < 0.05.ResultMean BP, total cholesterol, triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and median cotinine level were found to be significantly higher in PMT users than in controls (p < 0.001). Urinary cotinine level was positively correlated with mean BP, TC, TG, and LDL-C in PMT users (p < 0.001). Similarly, the odds of having hypercholesterolemia and increased diastolic BP was also significantly higher in PMT users (p < 0.001).ConclusionPMT use has an adverse effect on CV risk parameters and there is a rational of cotinine measurement for screening CV risk among PMT users. 相似文献

Background and aimsThe relationship between the body fat percentage (BFP) and hyperuricemia is still unknown in different gender subjects. The purpose of this study was to determine the magnitude of the association between the BFP and the presence of hyperuricemia in the sex-specific group among hypertensive patients.Methods and resultsWe conducted a cross-sectional study enrolling 14,234 hypertensive participates from the Chinese Hypertension Registry Study. Body fat percentage (BFP) was calculated by simple anthropometric parameters. Hyperuricemia was defined as serum uric acid (SUA) level 420 umol/L in men and 360 umol/L in women. The mean BFP was 24.5% in men and 37.1% in women. Multiple logistic analyses showed that the relationship between BFP with the risk of hyperuricemia in a dose-dependent manner among both men (odds ratio [OR] 1.07, 95% CI 1.06, 1.09) and women (OR 1.08, 95% CI 1.06, 1.09) in the fully adjusted model. Subgroup analyses showed the positive association between BFP and the risk of hyperuricemia was consistent in all stratification subgroups (all P for interaction >0.05).ConclusionFor patients with hypertension, BFP was positively associated with an increased risk of hyperuricemia among both men and women. 相似文献

Background and aimsCardio-metabolic diseases has been shown to be strongly associated with obesity. The aim of this study was to compare the predictive value of traditional and novel anthropometric measurement indices for cardio-metabolic diseases risk and evaluate whether new indicators can provide important information in addition to traditional indicators.Methods and resultsChina Health and Nutrition Survey (CHNS) data were obtained for this study. Baseline information for healthy participants was gathered from 1997 to 2004. The incidence of cardio-metabolic diseases was collected from 2009 to 2015 for cohort analysis. The predictive ability of each index for the risk of cardio-metabolic diseases was evaluated with time-dependent ROC analysis. Body mass index (BMI) showed the greatest predictive ability for cardio-metabolic disease incidence among all traditional and novel indices (Harrell's C statistic (95% CI): 0.7386 (0.7266–0.7507) for hypertension, 0.7496 (0.7285–0.7706) for diabetes, 0.7895 (0.7593–0.8196) for stroke and 0.7581 (0.7193–0.7969) for myocardial infarction). The addition of novel indices separately into the BMI model did not improve the predictive ability. Novel anthropometric measurement indices such as a body shape index (ABSI), abdominal volume index (AVI) and triponderal mass index (TMI), had a certain prediction ability for adults with BMI <24 kg/m2 compared to those with BMI ≥24 kg/m2.ConclusionNo strong evidence supports novel anthropometric measurement indices were better than BMI in the prediction of cardio-metabolic diseases incidence among Chinese adults. Novel anthropometric measurement indices, mainly for abdominal obesity, may have a high predictive effect for adults with BMI <24 kg/m2. 相似文献

Background and aimsThe strategic role of prevention in hypertension setting is well known but, with the only exception of annually events promoted by international scientific societies, no other screening campaigns are available. Aim of this study was to assess the feasibility of a non-physician pharmacy-based screening program and to describe the cardiovascular risk and the BP status of participating subjects.Methods and results2731 costumers participated to the screening program, answering to a questionnaire about personal cardiovascular risk and measuring their BP with an Omron HEM 1040-E. Since no threshold for hypertension diagnosis is currently available for community pharmacies BP measurements, we assessed high BP prevalence according to 3 different cut-offs (≥140/90, ≥135/85 and ≥ 130/80 mmHg) and compared normotensives and hypertensives on major cardiovascular risk factors. According to the proposed cut-offs, prevalence of hypertension was respectively of 31%, 45% and 59.5%, and it increased among younger subjects (31–65 y) when the lowest cut-offs were applied. High BP was found in a large percentage of subjects self-declared on-/not on-treatment (uncontrolled hypertensives) or normotensives (presumptive hypertensives) and among those not aware of their own BP values (presumptive hypertensives). Prevalence of CV risk factors was higher in hypertensives than in normotensives.ConclusionsOur findings demonstrated that a community pharmacy-based screening is feasible and attracts the interests of many subjects, improving awareness on their BP status. The screening was also showed to be useful in order to detect potentially uncontrolled and/or suspected new hypertensives, especially among young adults, to refer to general practitioners for confirmatory diagnosis or further evaluation. 相似文献

Background and aimsIn the less developed multi-ethnic regions (LEMRs) of Southwest China, the associations between dietary patterns and blood pressure (BP) values remain unclear. We aimed to investigate such associations and related effect modifiers.Methods and resultsThis study included 81,433 participants from the China Multi-Ethnic Cohort Study. Dietary intakes during the year before the interview were measured with the Quantitative Food Frequency Questionnaire. Three major dietary patterns that were highly in line with geographical and ethnic distributions of the study population, i.e., “Sichuan Basin,” “Yunnan-Guizhou Plateau,” and “Qinghai-Tibet Plateau,” were derived using principal component factor analysis. The multilinear regression model combined with inverse probability of exposure weighting was used to estimate the associations between dietary patterns and BP values.Comparing the highest with the lowest quintiles, the Sichuan Basin dietary pattern (characterized by urban lifestyles) was associated with 2.67 mmHg lower systolic blood pressure (SBP) (95% CI: −3.07 to −2.27) and 0.89 mmHg lower diastolic blood pressure (95% CI: −1.12 to −0.65). In contrast, both the Yunnan-Guizhou Plateau (characterized by agricultural lifestyles) and the Qinghai-Tibet Plateau dietary patterns (characterized by nomadic lifestyles) showed positive associations with BP. In the stratified analysis, the associations between dietary patterns and SBP were significantly stronger in women than in men for all three kinds of dietary patterns.ConclusionBoth major dietary patterns and their associations with BP showed a substantial disparity in LEMRs of Southwest China. Dietary patterns in regions of higher socioeconomic status are more conducive to reducing the rising of BP, especially for women and urban residents, which might provide insights into the BP control in LEMRs of Southwest China. 相似文献

Backgrounds and aimsThe cardiovascular risk conferred by concomitant prediabetes in hypertension is unclear. We aimed to examine the impact of prediabetes on incident heart failure (HF) and all-cause mortality, and to describe time in therapeutic blood pressure range (TTR) in a hypertensive real-world primary care population.Methods and resultsIn this retrospective cohort study, 9628 hypertensive individuals with a fasting plasma glucose (FPG) in 2006–2010 but no diabetes, cardiovascular or renal disease were followed to 2016; median follow-up was 9 years. Prediabetes was defined as FPG 5.6–6.9 mmol/L, and in a secondary analysis as 6.1–6.9 mmol/L. Study outcomes were HF and all-cause mortality. Hazard ratios (HR) were compared for prediabetes with normoglycemia using Cox regression. All blood pressure values from 2001 to the index date (first FPG in 2006–2010) were used to calculate TTR. At baseline, 51.4% had prediabetes. The multivariable-adjusted HR (95% confidence intervals) was 0.86 (0.67–1.09) for HF and 1.06 (0.90–1.26) for all-cause mortality. For FPG defined as 6.1–6.9 mmol/L, the multivariable-adjusted HR were 1.05 (0.80–1.39) and 1.42 (1.19–1.70), respectively. The prediabetic group had a lower TTR (p < 0.05).ConclusionsPrediabetes was not independently associated with incident HF in hypertensive patients without diabetes, cardiovascular or renal disease. However, prediabetes was associated with all-cause mortality when defined as FPG 6.1–6.9 mmol/L (but not as 5.6–6.9 mmol/L). TTR was lower in the prediabetic group, suggesting room for improved blood pressure to reduce incident heart failure in prediabetes. 相似文献

ObjectivesThe aim of this study was to test the hypothesis that echocardiographic strain imaging, by tracking subtle alterations in myocardial function, and cardiac magnetic resonance T1 mapping, by quantifying tissue properties, are useful and complement each other to detect acute cellular rejection in heart transplant recipients.BackgroundNoninvasive alternatives to endomyocardial biopsy are highly desirable to monitor acute cellular rejection.MethodsSurveillance endomyocardial biopsies, catheterizations, and echocardiograms performed serially according to institutional protocol since transplantation were retrospectively reviewed. Sixteen-segment global longitudinal strain (GLS) and circumferential strain were measured before, during, and after the first rejection and at 2 time points for patients without rejection using Velocity Vector Imaging for the first part of the study. The second part, with cardiac magnetic resonance added to the protocol, served to validate previously derived strain cutoffs, examine the progression of strain over time, and to determine the accuracy of strain and T1 measurements to define acute cellular rejection. All tests were performed within 48 h.ResultsMedian time to first rejection (16 grade 1 rejection, 15 grade ≥2 rejection) was 3 months (interquartile range: 3 to 36 months) in 49 patients. GLS and global circumferential strain worsened significantly during grade 1 rejection and ≥2 rejection and were independent predictors of any rejection. In the second part of the study, T1 time ≥1,090 ms, extracellular volume ≥32%, GLS >−14%, and global circumferential strain ≥−24% had 100% sensitivity and 100% negative predictive value to define grade ≥2 rejection with 70%, 63%, 55%, and 35% positive predictive values, respectively. The combination of GLS >−16% and T1 time ≥1,060 ms defined grade 1 rejection with 91% sensitivity and 92% negative predictive value. After successful treatment, T1 times decreased significantly.ConclusionsT1 mapping and echocardiographic GLS can serve to guide endomyocardial biopsy selectively. 相似文献

Background and aimsBlood pressure (BP) changes and insulin resistance (IR) are important cardiometabolic risk (CMR) factors; their early identification can contribute to the reduction of cardiovascular events in adulthood. This necessitates the search for more accessible and easily applied indicators for their prediction. Therefore, this study aimed to evaluate the predictive power of the indices, TyG, TG/HDL-c, height-corrected lipid accumulation product (HLAP), and visceral adiposity index (VAI), in identifying the CMR obtained by high BP and IR and to verify their relationship with biomarkers of endothelial dysfunction (ED) in European adolescents.Methods and resultsThe anthropometric data and blood biomarkers of 744 adolescents (343 boys and 401 girls) from the Healthy Lifestyle in Europe by Nutrition in Adolescence Cross-Sectional Study (HELENA-CSS), with a mean age of 14.67 (SD 1.15) years, were assessed. The adolescents were then classified according to the presence or absence of high BP and IR. The cut-off points of the indices evaluated for the identification of CMR were determined. The relationship between CMR diagnosed using these indices and ED biomarkers was tested. The HLAP and TG/HDL-c were fair predictors of CMR obtained by IR in male adolescents. These indices showed association with hsCRP in sVCAM-1 in boys, but it lost significance after adjusting for age and body mass index.ConclusionTG/HDL-c and HLAP indices showed a fair performance in predicting CMR, obtained by IR, in male adolescents. ED showed no association with the CMR identified by the indices. 相似文献

Background and aimsSeasonal variations in several risk factors for cardiovascular events (CVD) were described. Here, we evaluate the impact of seasonal variations in blood pressure (BP), lipid profile and glycemic control on estimated CVD risk in patients with type 2 diabetes (T2D).Methods and resultsRetrospective monocentric study of patients with T2D who were visited at least once in the winter period and once in the summer period, less than 8 months apart, for which data related to systolic (S) BP, diastolic (D) BP, body mass index, glycosylated hemoglobin (HbA1c), total cholesterol, HDL cholesterol and smoking habit were available on both occasions. The 10-year CVD risk was calculated using the UKPDS risk engine and the ASCVD risk estimator. As many as 411 patients were included in the study. Significant within-patient differences between summer and winter were found for the absolute risk of events assessed with both calculators (Δs-w UKPDS-CHD: ?1.33%, Δs-w UKPDS-Stroke: ?0.84%, Δs-w ASCVD: ?2.21%). The seasonal change in SBP was the main responsible for the change in risk estimated with both the UKPDS-Stroke (r2 = 0.43) and the ASCVD (r2 = 0.50) scores, while the change in total cholesterol was the main determinant of the change in risk for the UKPDS-CHD (r2 = 0.34). A significant correlation was identified between changes in temperature and changes in SBP (ρ = 0.130, p = 0.008), but not in other risk factors.ConclusionsSeasonal variations in the classic CVD risk factors influence the risk estimated using validated calculators. 相似文献

Background and aimThis study aimed to explore the association between uric acid (UA) and blood pressure (BP), included systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP).Methods and resultsA cross-sectional study with 22,478 individuals aged from 12 to 80 years (11,443 males and 11,035 females) from the National Health and Nutrition Examination Survey (NHANES) was performed. Multiple linear regression analysis was applied to explore the relationship between UA and BP, Stratified analysis and interaction were performed based on gender, race, age, body mass index (BMI), and alcohol consumption. Significantly positively associations were presented in SBP(β, 0.84 [95% CI, 0.67, 1.00]), DBP(β, 0.23 [95% CI, 0.11, 0.36]), and MAP (β, 0.43 [95% CI, 0.31, 0.55]). The associations were much more stronger between UA and SBP in females (β, 1.04 [95% CI, 0.78, 1.30], p for interaction 0.0003), black group (β, 1.17 [95% CI, 0.77, 1.56], p for interaction 0.0296), age (≥45) group (β, 1.03 [95% CI, 0.68, 1.39], p for interaction <0.0001) and drinking group (β, 0.98 [95% CI, 0.75, 1.21], p for interaction <0.0001). The significant interactions were found between UA and DBP in gender and alcohol consumption (all p for interaction <0.05). In terms of MAP, the significant interactions were found in race, age, and alcohol consumption (all p for interaction <0.05).ConclusionsA significantly positively association was found between UA and BP, including SBP, DBP, and MAP. 相似文献

BackgroundA total of 44.7% adults in China have hypertension, but the prevalence of primary aldosteronism (PA) in Chinese hypertensive patients is unknown.ObjectivesThis study prospectively investigated the prevalence, characteristics, and outcomes of PA in newly diagnosed hypertensive patients.MethodsIn a large community health center, consecutive hypertensive patients with an aldosterone-renin ratio >20 ng/mIU and plasma aldosterone concentration >10 ng/dl underwent captopril challenge test and/or saline infusion test for confirmation of PA. Adrenal computed tomography scan and adrenal vein sampling were used for subtyping. PA patients treated with surgery or medication were followed up for 1 year, and outcomes after treatment were evaluated.ResultsIn total, 1,020 newly diagnosed hypertensive patients were screened over 16 months, of whom 40 were diagnosed with PA, 948 with non-PA, 32 with probable PA, resulting in a prevalence of more than 4.0%. Compared with non-PA, PA patients more frequently displayed microalbuminuria (p = 0.031), but the incidence of cardiovascular events was not different (p = 0.927). For surgically treated patients (n = 7), a complete biochemical success rate was 100% and a complete clinical success rate was 85.7%. For medically treated patients (n = 29), the proportion with optimal blood pressure control was 79%, and among them, 91% (21 of 23) only needed 1 antihypertensive drug: the mineralocorticoid receptor antagonist.ConclusionsThe prevalence of PA in patients with newly diagnosed hypertension in China was at least 4%. PA screening in newly diagnosed hypertensive patients leads to good clinical outcomes. (Primary Aldosteronism In Hypertensive Patients in China [PA-China]; NCT03155139) 相似文献
