In this prospective study, a total of 5247 individuals with abnormal AS (at baseline) and repeated brachial-ankle pulse wave velocity (baPWV) measurement before 2018 years were enrolled from the Kailuan Study. According the second baPWV measurement, we divided the participants into two groups, improved AS (defined as transfer elevated AS status to normal) and persistent AS (defined as maintaining elevated AS status). The outcome was a composite event of stroke, myocardial infraction, and all-cause mortality. We used Cox proportional hazards regression to examine the association between AS status at the follow-up and the subsequent outcome. During a median of 5.2 years follow-up, we observed 413 end point events. After adjusted for potential confounders, comparing with the persistent AS group, individuals in the improved AS group had a 43% (hazard ratio [HR], 0.57; 95% confidence interval [CI] 0.35–0.94) decreased the risk of the primary composite events. We also found a baPWV decrease of 1 m/s was associated with a 3% decreased risk (HR, 0.97; 95% CI 0.94–0.99) for primary composite events. We further demonstrated that younger than 60 years, non-smoker, non-hypertension, and non-diabetes were associated with improved the AS status. In conclusion, improving AS status may reduce the risk of clinical events. In the future, more research should be performed to explore the target for improving the AS status.","PeriodicalId":16070,"journal":{"name":"Journal of Human Hypertension","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139981346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ST, LPA and MVPA were assessed with ActiGraph accelerometer. ST and LPA were sex-categorised in tertiles as low (reference), moderate and high, while MVPA was categorised as <40 min/day (reference), 40–<60 min/day and ≥60 min/day. cfPWV, cIMT and carotid elasticity were measured with Vicorder and ultrasound. Fat mass and lean mass were assessed with dual-energy X-ray absorptiometry and homeostatic model assessment of insulin resistance (HOMA-IR) was computed. Mediation analyses structural equation models and linear mixed-effect models adjusted for cardiometabolic and lifestyle factors were conducted. Among 1574 adolescents [56.2% female; mean (SD) age 15.4 (0.24) years], 41% males and 17% females accumulated ≥60 min/day of MVPA. Higher ST was associated with lower cIMT partly mediated by lean mass. Higher LPA (standardized β = −0.057; [95% CI −0.101 to −0.013; p = 0.014]) and the highest LPA tertile were associated with lower cfPWV.

Lean mass partially mediated associations of higher MVPA with higher cIMT (0.012; [0.007–0.002; p = 0.001], 25.5% mediation) and higher carotid elasticity (0.025; [0.014–0.039; p = 0.001], 28.1% mediation). HOMA-IR mediated the associations of higher MVPA with higher carotid elasticity (7.7% mediation). Engaging in ≥60 min/day of MVPA was associated with higher carotid elasticity.

We identified four different data sources describing the association between sodium reduction, potassium supplementation and change in SBP. We then fitted a series of models to estimate the SBP reductions expected for the differences in sodium and potassium intake in SSaSS, derived from 24-h urine collections. The proportions of the SBP reduction separately attributable to sodium reduction and potassium supplementation were calculated. The observed SBP reduction in SSaSS was −3.3 mmHg with a corresponding mean 15.2 mmol reduction in 24-h sodium excretion and a mean 20.6 mmol increase in 24-h potassium excretion. Assuming 90% of dietary sodium intake and 70% of dietary potassium intake were excreted through urine, the models projected falls in SBP of between −1.67 (95% confidence interval: −4.06 to +0.73) mmHg and −5.33 (95% confidence interval: −8.58 to −2.08) mmHg. The estimated proportional contribution of sodium reduction to the SBP fall ranged between 12 and 39% for the different models fitted. Sensitivity analyses assuming different proportional urinary excretion of dietary sodium and potassium intake showed similar results. In every model, the majority of the SBP lowering effect in SSaSS was estimated to be attributable to the increase in dietary potassium rather than the fall in dietary sodium.","PeriodicalId":16070,"journal":{"name":"Journal of Human Hypertension","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41371-024-00896-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139912769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Screen-detected hypertension was verified by home blood pressure measurements. Lifestyle counseling was provided for all participants and preventive medications were started or intensified if needed. All-cause and cardiovascular mortality were obtained from the official statistics. Screen-detected hypertension was diagnosed in 17% of the participants, 51% were normotensive and 32% had antihypertensive medication at baseline. The screen-detected hypertensives had higher mean blood pressure and cholesterol levels than the two other groups.

However, the causal association between BP and frailty remains not well determined. The purpose of this bi-directional two-sample Mendelian randomization (MR) study was to investigate the causal relationship between BP and frailty. Independent single nucleotide polymorphisms (SNPs) strongly (P < 5E-08) associated with systolic BP (SBP), diastolic BP (DBP), and pulse pressure (PP) were selected as instrumental variables. Two different published genome-wide association studies (GWAS) on BP from the CHARGE (n = 810,865) and ICBP (n = 757,601) consortia were included. Summary-level data on frailty index (FI) were obtained from the latest GWAS based on UK Biobank and Swedish TwinGene cohorts (n = 175,226). Inverse variance weighted (IVW) approach with other sensitivity analyses were used to calculate the causal estimate. Using the CHARGE dataset, genetic predisposition to increased SBP (β = 0.135, 95% CI = 0.093 to 0.176, P = 1.73E-10), DBP (β = 0.145, 95% CI = 0.104 to 0.186, P = 3.14E-12), and PP (β = 0.114, 95% CI = 0.070 to 0.157, p = 2.87E-07) contributed to a higher FI, which was validated in the ICBP dataset. There was no significant causal effect of FI on SBP, DBP, and PP. Similar results were obtained from different MR methods, indicating good stability. There was potential heterogeneity detected by Cochran’s Q test, but no horizontal pleiotropy was observed in MR-Egger intercept test (P > 0.05). These findings evinced that higher BP and PP were causally associated with an increased risk of frailty, suggesting that controlling hypertension could reduce the risk of frailty.","PeriodicalId":16070,"journal":{"name":"Journal of Human Hypertension","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139741208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
