RESUMEN
BACKGROUND: Hypertension may harm cognitive performance, but the potential correlates of longitudinal patterns of blood pressure (BP), especially diastolic BP (DBP), to cognition have been unclear. OBJECTIVES: To examine long-term BP trajectories in relation to subsequent cognitive decline, incident dementia and all-cause mortality in the general population. DESIGN: Population-based cohort study. SETTING: Communities in England. PARTICIPANTS: The study included 7566 participants from the English Longitudinal Study of Ageing (ELSA). MEASUREMENTS: BP were measured in 1998, 2004, 2008. Group-based trajectory modeling was used to identify long-term patterns of systolic BP (SBP) and DBP. Outcomes including cognitive function, incident dementia, and all-cause mortality were followed up to 10 years. RESULTS: Five distinct trajectories were identified for SBP and DBP, respectively. The normal-stable trajectory was used as the reference. For cognitive decline, both SBP and DBP trajectories were independently associated with subsequent cognitive decline, with the fastest decline appeared in the high-stable SBP group of 180 mmHg and the low-stable DBP group of 60 mmHg (both P<0.005). For incident dementia, the multivariable adjusted hazard ratio (HR) was also greatest in high-stable group (4.79, 95% confidence interval: 2.84 to 8.07) across all SBP trajectories. Conversely, low (HR: 1.58) and moderate-low stable (HR: 1.56) DBP trajectories increased dementia risk (both P<0.005). Similar patterns were found in BP trajectories in relation to all-cause mortality. CONCLUSION: Our study evaluates the potential health impact from different BP trajectories and suggests that controlling long-term SBP and maintaining adequate DBP may be relevant for the current practice to promote cognitive health and extend lifespan.

Background: There are gender differences in hypertension and the effect of gender on the relationship between systemic immune-inflammation index (SII) and mortality in hypertensive patients is unclear. Methods: Hypertensive patients (n=7444) from ten cycles of the National Health and Nutrition Examination Survey (NHANES) spanning 1999 to 2018 were enrolled in this study. The maximally selected rank statistics method was employed to identify the optimal cut-off value for the SII. Survey-weighted Cox regression analysis was utilized to explore the links between SII and all-cause and cardiovascular mortality. Kaplan-Meier method and time-dependent receiver operating characteristic curve analysis was conducted to assess the predictive accuracy of SII for mortality. Results: Whether SII was considered as a numerical variable or as a binary variable (higher- and lower-SII groups), higher SII levels were associated with a higher risk of all-cause and cardiovascular mortality in female hypertensive patients (all P < 0.001), but no such association was observed in the males. The area under the curve of the SII was 0.602, 0.595, and 0.569 for 3-, 5-, and 10-year all-cause mortality, respectively, in females, but was 0.572, 0.548, and 0.554 in males. High SII levels interacted with the poverty income ratio and physical activity to affect mortality in the male population (P for interaction < 0.05), and there was an interaction between race and SII in the female cardiovascular mortality rate (P for interaction < 0.05). Conclusion: Higher levels of SII may be closely related to the high risk of all-cause and cardiovascular mortality in hypertensive patients, and the results showed that this relationship is more significant and stable in the female group. High SII interacts with PIR, physical activity, and race to affect the mortality rate in different gender populations.

BACKGROUND: Chronic kidney disease (CKD) is an independent risk factor for cardiovascular disease, development of end-stage renal disease, and all-cause mortality. It affects around 10% of the population worldwide. The prevalence of hypertension in people with CKD ranges from 22% in stage 1 to 80% in stage 4. Elevated arterial blood pressure is one of the major independent risk factors for adverse cardiovascular events. Thereby, reducing blood pressure to below standard targets may be beneficial but could also increase the risk of adverse events. The optimal blood pressure target in people with hypertension and CKD remains unknown. OBJECTIVES: Primary: to compare the effects of standard and lower-than-standard blood pressure targets for hypertension in people with chronic kidney disease on mortality and morbidity outcomes. Secondary: to assess the magnitude of reductions in systolic and diastolic blood pressure, the proportion of participants reaching blood pressure targets, and the number of drugs necessary to achieve the assigned target. SEARCH METHODS: We used standard, extensive Cochrane search methods. We searched the Cochrane Hypertension Specialized Register, CENTRAL, MEDLINE, Embase, one other database, and two trial registers up to 8 February 2023. We also contacted authors of relevant papers regarding further published and unpublished work. We applied no language restrictions. SELECTION CRITERIA: We included randomized controlled trials (RCTs) in people with hypertension and CKD that provided at least twelve months' follow-up. Eligible interventions compared lower targets for systolic/diastolic blood pressure (130/80 mmHg or lower) to standard targets for blood pressure (140 to 160/90 to 100 mmHg or lower). Participants were adults with CKD and elevated blood pressure documented in a standard way on at least two occasions, or already receiving treatment for elevated blood pressure. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our critical outcomes were: total mortality, total serious adverse events, total cardiovascular events, cardiovascular mortality, and progression to end-stage renal disease. Important outcomes were: participant withdrawals due to adverse effects, and number of participants with a doubling of serum creatinine level or at least a 50% reduction in the glomerular filtration rate (GFR) at the end of the study. We used GRADE to assess the certainty of the evidence for the critical outcomes. This review received no funding. MAIN RESULTS: We included six RCTs that contributed data for meta-analysis, involving 7348 participants overall (range 840 to 4733 people per study). The mean follow-up was 3.6 years (range 1.0 to 8.0 years). Three studies were publicly funded, two were privately funded, and one had both public and private funding. All RCTs provided individual participant data. None of the included studies blinded participants or clinicians because of the need to titrate antihypertensive drugs to reach a specific blood pressure target. However, an independent committee blinded to group allocation assessed clinical events in all studies. Critical outcomes. Compared with standard blood pressure targets, lower targets likely result in little to no difference in total mortality (risk ratio (RR) 0.90, 95% confidence interval (CI) 0.76 to 1.06; 6 studies, 7348 participants), total serious adverse events (RR 1.01, 95% CI 0.94 to 1.08; 6 studies, 7348 participants), and total cardiovascular events (RR 1.00, 95% CI 0.87 to 1.15; 5 studies, 6508 participants), all with moderate-certainty evidence. Compared with standard blood pressure targets, lower targets may result in little to no difference in cardiovascular mortality (RR 0.90, 95% CI 0.70 to 1.16; 6 studies, 7348 participants) and progression to end-stage renal disease (RR 0.94, 95% CI 0.80 to 1.11; 4 studies, 4788 participants), both with low-certainty evidence. Important outcomes. We found little to no differences in: participant withdrawals due to adverse effects; and the number of participants with a doubling of serum creatinine level, or at least a 50% reduction in GFR at the end of the study. Exploratory outcomes. Compared to the standard blood pressure target groups, participants in the lower target groups achieved lower systolic and diastolic blood pressure values after one year, and required a higher number of antihypertensive drugs at the end of the studies. A higher proportion of participants in the standard blood pressure target groups achieved the targets they were assigned than did participants in the intensive target groups. AUTHORS' CONCLUSIONS: Compared to a standard blood pressure target, lower blood pressure targets probably result in little to no difference in total mortality, total serious adverse events, and total cardiovascular events, and may result in little to no difference in total cardiovascular mortality or in the progression to end-stage renal disease in people with hypertension and CKD. However, the evidence underpinning these conclusions has several limitations. All studies were open design, blood pressure measurement was performed at a medical office, and there was scant information about adverse events. Future research should include high-quality adverse event data, report results for people with different levels of proteinuria, and consider out-of-office blood pressure monitoring. Several studies are ongoing, and may provide new evidence for this topic in the near future.

Sepsis and hypertension pose significant health risks, yet the optimal mean arterial pressure (MAP) target for resuscitation remains uncertain. This study investigates the association between average MAP (a-MAP) within the initial 24 h of intensive care unit admission and clinical outcomes in patients with sepsis and primary hypertension using the Medical Information Mart for Intensive Care (MIMIC) IV database. Multivariable Cox regression assessed the association between a-MAP and 30-day mortality. Kaplan-Meier and log-rank analyses constructed survival curves, while restricted cubic splines (RCS) illustrated the nonlinear relationship between a-MAP and 30-day mortality. Subgroup analyses ensured robustness. The study involved 8,810 patients. Adjusted hazard ratios for 30-day mortality in the T1 group (< 73 mmHg) and T3 group (≥ 80 mmHg) compared to the T2 group (73-80 mmHg) were 1.25 (95% CI 1.09-1.43, P = 0.001) and 1.44 (95% CI 1.25-1.66, P < 0.001), respectively. RCS revealed a U-shaped relationship (non-linearity: P < 0.001). Kaplan-Meier curves demonstrated significant differences (P < 0.0001). Subgroup analysis showed no significant interactions. Maintaining an a-MAP of 73 to 80 mmHg may be associated with a reduction in 30-day mortality. Further validation through prospective randomized controlled trials is warranted.

Background: To date, no studies have investigated the correlation between the neutrophil-to-lymphocyte ratio (NLR) and the long-term risk of mortality in individuals with both coronary heart disease (CHD) and hypertension. This study aims to evaluate the association between NLR and all-cause and cardiovascular mortality among this patient population. Methods: National Death Index (NDI) and National Health and Nutrition Examination Survey (NHANES 2001-2018) were the data sources. A nonlinear association between the NLR and mortality risk was shown by restricted cubic spline (RCS) analysis. Using a weighted Cox proportional hazards model, we quantitatively evaluated the effect of NLR on mortality risk.The capacity of NLR to forecast survival was assessed by evaluating time-dependent receiver operating characteristic (ROC) curves. A mediating influence analysis was conducted to assess the influence of NLR on mortality through eGFR as a mediator. Results: The study involved a total of 2136 individuals. During the median follow-up interval of 76.0 months, 801 deaths were recorded. The RCS analysis showed NLR and mortality risk to have a nonlinear relationship. Two groups were established based on the participants' NLR levels: a group with high NLR (NLR > 2.65) and a group with low NLR (NLR < 2.65). After adjusting for potential confounding factors, the Cox proportional hazards model revealed that participants with an increased NLR faced a significantly higher risk of cardiovascular mortality. (HR 1.58, 95% CI 1.33-1.82, p < 0.0001) and all-cause mortality (HR 1.46, 95% CI 1.30-1.62, p < 0.0001). An analysis of interactions and data stratification corroborated the validity of our findings. eGFR was identified as a partial mediator in the association between NLR and mortality rates, contributing 12.17% and 9.66% of the variance in all-cause and cardiovascular mortality, respectively. The predictive performance for cardiovascular mortality was quantified using ROC curves, with respective AUC values of 0.67, 0.65, and 0.64 for predictions over 3, 5, and 10 years. The AUC values for all-cause mortality were 0.66, 0.64, and 0.63 for the same time frames. Conclusion: For patients with CHD and hypertension, an elevated NLR serves as an independent prognostic indicator for both all-cause and cardiovascular mortality.

BACKGROUND: There is a growing burden of non-obese people with diabetes mellitus (DM). However, their cardiovascular risk (CV), especially in the presence of cardiovascular-kidney-metabolic (CKM) comorbidities is poorly characterised. The aim of this study was to analyse the risk of major CV adverse events in people with DM according to the presence of obesity and comorbidities (hypertension, chronic kidney disease, and dyslipidaemia). METHODS: We analysed persons who were enrolled in the prospective Silesia Diabetes Heart Project (NCT05626413). Individuals were divided into 6 categories according to the presence of different clinical risk factors (obesity and CKM comorbidities): (i) Group 1: non-obese with 0 CKM comorbidities; (ii) Group 2: non-obese with 1-2 CKM comorbidities; (iii) Group 3: non-obese with 3 CKM comorbidities (non-obese "extremely unhealthy"); (iv) Group 4: obese with 0 CKM comorbidities; (v) Group 5: obese with 1-2 CKM comorbidities; and (vi) Group 6: obese with 3 CKM comorbidities (obese "extremely unhealthy"). The primary outcome was a composite of CV death, myocardial infarction (MI), new onset of heart failure (HF), and ischemic stroke. RESULTS: 2105 people with DM were included [median age 60 (IQR 45-70), 48.8% females]. Both Group 1 and Group 6 were associated with a higher risk of events of the primary composite outcome (aHR 4.50, 95% CI 1.20-16.88; and aHR 3.78, 95% CI 1.06-13.47, respectively). On interaction analysis, in "extremely unhealthy" persons the impact of CKM comorbidities in determining the risk of adverse events was consistent in obese and non-obese ones (Pint=0.824), but more pronounced in individuals aged < 65 years compared to older adults (Pint= 0.028). CONCLUSION: Both non-obese and obese people with DM and 3 associated CKM comorbidities represent an "extremely unhealthy" phenotype which are at the highest risk of CV adverse events. These results highlight the importance of risk stratification of people with DM for risk factor management utilising an interdisciplinary approach.

BACKGROUND: The association between ambient temperature and mortality has yielded inconclusive results with previous studies relying on in-patient data to assess the health effects of temperature. Therefore, we aimed to estimate the effect of ambient temperature on non-accidental mortality among elderly hypertensive patients through a prospective cohort study conducted in northeastern China. METHODS: A total of 9634 elderly hypertensive patients from the Kailuan research who participated in the baseline survey and follow-up from January 1, 2006 to December 31, 2017, were included in the study. We employed a Poisson generalized linear regression model to estimate the effects of monthly ambient temperature and temperature variations on non-accidental mortality. RESULTS: After adjusting for meteorological parameters, the monthly mean temperature (RR = 0.989, 95% CI: 0.984-0.993, p < 0.001), minimum temperature (RR = 0.987, 95% CI: 0.983-0.992, p < 0.001) and maximum temperature (RR = 0.989, 95% CI: 0.985-0.994, p < 0.001) exhibited a negative association with an increased risk of non-accidental mortality. The presence of higher monthly temperature variation was significantly associated with an elevated risk of mortality (RR = 1.097, 95% CI:1.051-1.146, p < 0.001). Further stratified analysis revealed that these associations were more pronounced during colder months as well as among male and older individuals. CONCLUSIONS: Decreased temperature and greater variations in ambient temperature were observed to be linked with non-accidental mortality among elderly hypertensive patients, particularly notable within aging populations and males. These understanding regarding the effects of ambient temperature on mortality holds clinical significance for appropriate treatment strategies targeting these individuals while also serving as an indicator for heightened risk of death.

BACKGROUND: Blood pressure readings taken before anesthesia often influence the decision to delay or cancel elective surgeries. However, the implications of these specific blood pressure values, especially how they compare to baseline, on postoperative in-hospital 30-day mortality remain underexplored. This research aimed to examine the effect of discrepancies between the baseline blood pressure evaluated in the ward a day before surgery, and the blood pressure observed just before the administration of anesthesia, on the postoperative mortality risks. METHODS: The study encompassed 60,534 adults scheduled for non-cardiac surgeries at a tertiary care center in Seoul, Korea. Baseline blood pressure was calculated as the mean of the blood pressure readings taken within 24 hours prior to surgery. The preanesthetic blood pressure was the blood pressure measured right before the administration of anesthesia. We focused on in-hospital 30-day mortality as the primary outcome. RESULTS: Our research revealed that a lower preanesthetic systolic or mean blood pressure that deviates by 20 mmHg or more from baseline significantly increased the risk of 30-day mortality. This association was particularly pronounced in individuals with a history of hypertension and those aged 65 and above. Higher preanesthetic blood pressure was not significantly associated with an increased risk of 30-day mortality. CONCLUSION: We found that a lower preanesthetic blood pressure compared to baseline significantly increased the 30-day postoperative mortality risk, whereas a higher preanesthetic blood pressure did not. Our study emphasizes the critical importance of accounting for variations in both baseline and preanesthetic blood pressure when assessing surgical risks and outcomes.

Current studies have not clarified the relationship between riboflavin intake and all-cause mortality in patients with chronic kidney disease (CKD). The aim of this study is to investigate whether there is an association between riboflavin intake and the risk of all-cause mortality in patients with CKD. This was a retrospective cohort study with data extracted from the National Health and Nutrition Examination Survey (NHANES). The study was conducted using Cox regression analysis to calculate hazard ratio (HR) and 95% confidence interval (CI) to assess the association between riboflavin intake and risk of all-cause mortality. Subgroup analyses were performed regarding gender, CKD stage, hypertension, hyperlipidemia and cardiovascular disease (CVD). A total of 3750 patients were ultimately included in the analyses. After excluding potential confounders, lower intake of riboflavin was associated with the higher risk of all-cause mortality (Q1: HRâ =â 1.33, 95% CI: 1.05-1.69). The similar association was also found in patients at mild/moderate stage (HRâ =â 1.32, 95% CI: 1.05-1.66), in female (HRâ =â 1.35, 95% CI: 1.01-1.81), with hypertension (HRâ =â 1.37, 95% CI: 1.07-1.75), CVD (HRâ =â 1.48, 95% CI: 1.08-2.03), and dyslipidemia (HRâ =â 1.29, 95% CI: 1.01-1.66). This study found the association between low riboflavin intake and high risk of all-cause mortality, indicating a potential beneficial role of riboflavin in CKD patients.

Background: Particulate pollution, especially PM2.5from biomass burning, affects public and human health in northern Thailand during the dry season. Therefore, PM2.5exposure increases non-communicable disease incidence and mortality. This study examined the relationship between PM2.5and NCD mortality, including heart disease, hypertension, chronic lung disease, stroke, and diabetes, in northern Thailand during 2017-2021. Methods: The analysis utilized accurate PM2.5data from the MERRA2 reanalysis, along with ground-based PM2.5measurements from the Pollution Control Department and mortality data from the Division of Non-Communicable Disease, Thailand. The cross-correlation and spearman coefficient were utilized for the time-lag, and direction of the relationship between PM2.5and mortality from NCDs, respectively. The Hazard Quotient (HQ) was used to quantify the health risk of PM2.5to people in northern Thailand. Results: High PM2.5 risk was observed in March, with peak PM2.5concentration reaching 100 µg/m3, with maximum HQ values of 1.78 ± 0.13 to 4.25 ± 0.35 and 1.45 ± 0.11 to 3.46 ± 0.29 for males and females, respectively. Hypertension significantly correlated with PM2.5levels, followed by chronic lung disease and diabetes. The cross-correlation analysis showed a strong relationship between hypertansion mortality and PM2.5at a two-year time lag in Chiang Mai (0.73) (CI [-0.43-0.98], p-value of 0.0270) and a modest relationship with chronic lung disease at Lampang (0.33) (a four-year time lag). The results from spearman correlation analysis showed that PM2.5concentrations were associated with diabetes mortality in Chiang Mai, with a coefficient of 0.9 (CI [0.09-0.99], p-value of 0.03704). Lampang and Phayao had significant associations between PM2.5 and heart disease, with coefficients of 0.97 (CI [0.66-0.99], p-value of 0.0048) and 0.90 (CI [0.09-0.99], p-value of 0.0374), respectively, whereas Phrae had a high coefficient of 0.99 on stroke.

BACKGROUND: Resistant hypertension is characterized by elevated blood pressure (BP) despite using 3 antihypertensive agents. Ambulatory BP monitoring (ABPM) detects the presence of white-coat resistant hypertension (24-hour BP <130/80 mmâ Hg). The aim of the study was to evaluate risks of death in resistant hypertension compared with controlled hypertension, as well as in ABPM-confirmed (24-hour BP ≥130 or 80 mmâ Hg), versus white-coat resistant hypertension. METHODS: We selected 8146 patients with controlled hypertension (office BP <140/90 mmâ Hg while being treated with ≤3 antihypertensive drugs) and 8577 with resistant hypertension (BP ≥140 or ≥90 mmâ Hg while being treated with ≥3 drugs). All-cause and cardiovascular mortalities (median follow-up, 9.7 years) were compared between groups, as well as between patients with white-coat (3289) and ABPM-confirmed (5288) resistant hypertension. Hazard ratios (HRs) from Cox models after adjustment for clinical confounders were used for comparisons. RESULTS: Compared with controlled hypertension, resistant hypertension was associated with an increased risk in all-cause (HR, 1.21 [95% CI, 1.12-1.30]) and cardiovascular mortalities (HR, 1.33 [95% CI, 1.17-1.51]) in confounder-adjusted models. Compared with white-coat, ABPM-confirmed resistant hypertension was associated with an increased risk of all-cause (HR, 1.45 [95% CI, 1.32-1.60]) and cardiovascular (HR, 1.68 [95% CI, 1.43-1.98]) mortalities. When ABPM-confirmed and white-coat resistant hypertension were separately compared with controlled hypertension, only the former was associated with an increased risk of death and cardiovascular death (HR, 1.36 [95% CI, 1.26-1.48] and 1.56 [95% CI, 1.36-1.79]), respectively. CONCLUSIONS: ABPM-confirmed resistant hypertension is associated with an increased risk of death and cardiovascular death with respect to both controlled hypertension and white-coat resistant hypertension.

BACKGROUND: The American Heart Association (AHA) recently defined a new concept of cardiovascular health-Life's Essential 8 (LE8). We sought to examine whether LE8 score is associated with a risk of all-cause and cardiovascular disease (CVD)-related mortality in individuals with hypertension. METHODS: This longitudinal study analyzed data from the National Health and Nutrition Examination Survey from 2007 to 2018 in people 20 years or older with hypertension. LE8 score (range 0-100) was measured according to the AHA definition and divided into unweighted tertiles into groups T1 (< 50.00), T2 (50.00-61.25), and T3 (≥ 61.25). Primary outcomes included all-cause mortality and CVD-specific mortality. RESULTS: A total of 15,318 individuals with hypertension were included in this study, with a mean ± standard error age of 55.06 ± 0.25 years. During the median follow-up period of 76 months, 2525 all-cause mortality occurred, of which 806 were due to CVD. Compared with participants with hypertension in the T1 group, those in T2 and T3 respectively had 28% (adjusted HR = 0.72, 95% CI 0.63-0.83, P < 0.001) and 39% (adjusted HR = 0.61, 95% CI 0.52-0.72, P < 0.001) lower risk of all-cause mortality, the T2 and T3 groups were associated with 32% (adjusted HR = 0.68, 95% CI 0.53-0.88, P = 0.003) and 36% (adjusted HR = 0.64, 95% CI 0.49-0.84, P = 0.001) reduced risk of CVD mortality separately. CONCLUSIONS: A higher LE8 score is associated with a lower risk of all-cause mortality and CVD mortality, and the higher LE8 score can be maintained in the clinic to improve prognosis by modifying the diet and lifestyle habits of individuals with hypertension.

BACKGROUND AND AIMS: Malnutrition is associated with poor outcomes in patients with chronic diseases. The aim of this study is to investigate the prevalence of malnutrition in patients with hypertension and relationship between malnutrition severity and long-term mortality in these patients. METHODS AND RESULTS: The study included 11,278 patients with hypertension from the National Health and Nutrition Examination Survey database. The degree of malnutrition was assessed using the Controlled Nutritional Status score, with patients divided into normal, mild, and moderate-to-severe groups. After 10 years of follow-up, the results showed that patients who died had higher CONUT scores, poorer nutritional status, and lower albumin, total cholesterol, and lymphocytes than those who survived (P < 0.05). The Kaplan-Meier analysis revealed that patients with poor nutritional status had a significantly higher risk of all-cause death. In the Non-Lipid Lowering Drugs group, the CONUT score (hazard ratio (HR): 1.225; 95% confidence interval (CI): 1.162-1.292; P < 0.0001), as well as mild (HR: 1.532; 95% CI 1.340-1.751; P < 0.0001) and moderate-to-severe malnutrition (HR: 2.797; 95% CI: 1.441-5.428; P = 0.0024), were independent predictors of long-term mortality. The competing risk regression models showed that cardiovascular and cerebrovascular mortality increased with increasing CONUT scores. The results were robust in both subgroup and sensitivity analyses. CONCLUSIONS: Malnutrition significantly impacts long-term mortality in hypertensive patients. The CONUT score may be a useful tool for assessing the nutritional status of patients with hypertension in the non-lipid-lowering population and for predicting their long-term mortality.

We investigated fasting hypertriglyceridemia as predictors of all-cause, cardiovascular, and non-cardiovascular mortality in an elderly male Chinese population, while accounting for various conventional cardiovascular risk factors. Our participants were elderly men recruited from residents living in a suburban town of Shanghai (≥60 years of age, n = 1583). Hypertriglyceridemia was defined as a fasting serum triglycerides concentration ≥1.70 mmol/L. Subgroup analyses were performed according to current smoking (yes vs. no), alcohol intake (yes vs. no), and the presence and absence of hypertension and hyperglycemia. During a median of 7.9 years follow-up, all-cause, cardiovascular, and non-cardiovascular deaths occurred in 279, 112, and 167 participants, respectively. After adjustment for confounding factors, fasting hypertriglyceridemia was not significantly (p ≥ .33) associated with the risk of all-cause, cardiovascular, and non-cardiovascular mortality. However, there was significant (p = .03) interaction between hypertriglyceridemia and the presence and absence of hypertension in relation to all-cause mortality. In normotensive, but not hypertensive individuals, hypertriglyceridemia was significantly associated with a higher risk of all-cause mortality (hazard ratio 1.57, 95% confidence interval 1.06-2.31). In further non-parametric analyses in normotensive individuals, the age-standardized rate for all-cause mortality increased from 18.9 in quartile 1 to 20.0, to 24.7, and to 39.9 per 1000 person-years in quartiles 2, 3, and 4 of serum triglycerides concentration, respectively (ptrend = .0004). Similar results were observed for cardiovascular mortality. Our study in elderly male Chinese showed that fasting hypertriglyceridemia was associated with a higher risk of all-cause and cardiovascular mortality in patients with normotension but not those with hypertension.

The serum uric acid to serum creatinine ratio (SUA/sCr) is a standardized index of renal function. More importance was attached to the significance of this ratio in the progression of hypertension. While the association between the prognosis of hypertension and SUA/sCr is unknown. Therefore, we aimed to prospectively examine the associations of serum uric acid to serum creatinine ratio and all-cause and CVD mortality in adults with hypertension. Participants with hypertension from NHANES 1999-2018 (n = 15,269) were included. They were stratified by 1 increment of SUA/sCr ratio and categorized into 6 groups as ≤ 4, > 4 to 5, > 5 to 6, > 6 to 7, > 7 to 8, and > 8. The reason for categorization in 6 groups was to analyze the influence of different ratios on outcomes accurately and provide more precise guidance. The sample size is large enough that even if divided into 6 groups, it does not affect the statistical power. The primary outcomes were all-cause and CVD mortality. Weighted multivariable Cox proportional hazards regression models were used to estimate hazard ratio (HRs) of mortality. Restricted cubic spline regression models were utilized to examine dose-response associations between the serum uric acid to serum creatinine ratio and all-cause and CVD mortality. Relatively comprehensive stratified analyses were conducted to confirm the accuracy and stability of the results. There were 15,269 total participants, 49.4% of whom were men, with an average age of 56.6 years. Weighted multivariable Cox proportional hazards regression models demonstrated participants in the lowest group (≤ 4) had the HRs (95% CIs) of 1.43 (1.18, 1.73) for all-cause mortality and 2.8 (1.92, 4.10) for CVD mortality when compared to the reference group. Participants in the highest group (> 8) had the HRs (95% CIs) of 0.47 (0.25, 0.89) for CVD mortality when compared to the reference group. There were progressively lower risks for all-cause and CVD mortality with the SUA/sCr ratio increased (both P trend < 0.01). The SUA/sCr ratio was (P for nonlinearity < 0.01) nonlinearly correlated with all-cause mortality, with inflection points of 6.25. In addition, the restricted cubic splines results indicated that the SUA/sCr ratio (P for nonlinearity = 0.32) showed linear and negative associations with cardiovascular mortality with inflection points of 6.54. The inverse associations between SUA/sCr ratio and all-cause mortality were consistent across all subgroups except for the subgroup of eGFR < 45 ml/min/1.73 m2 and never smokers (P trend = 0.20 and 0.13, respectively), and the inverse associations between low SUA/sCr ratio and CVD mortality were consistent across all subgroups (P trend < 0.01). Contrary to previous studies, outcomes suggest that lower SUA/sCr ratio was associated with higher risks of all-cause and CVD mortality in adults with hypertension.

BACKGROUND: Deprescribing of antihypertensive medications is recommended for some older patients with low blood pressure and frailty. The OPTiMISE trial showed that this deprescribing can be achieved with no differences in blood pressure control at 3 months compared with usual care. We aimed to examine effects of deprescribing on longer-term hospitalisation and mortality. METHODS: This randomised controlled trial enrolled participants from 69 general practices across central and southern England. Participants aged 80 years or older, with systolic blood pressure less than 150 mm Hg and who were receiving two or more antihypertensive medications, were randomly assigned (1:1) to antihypertensive medication reduction (removal of one antihypertensive) or usual care. General practitioners and participants were aware of the treatment allocation following randomisation but individuals responsible for analysing the data were masked to the treatment allocation throughout the study. Participants were followed up via their primary and secondary care electronic health records at least 3 years after randomisation. The primary outcome was time to all-cause hospitalisation or mortality. Intention-to-treat analyses were done using Cox regression modelling. A per-protocol analysis of the primary outcome was also done, excluding participants from the intervention group who did not reduce treatment or who had medication reinstated during the initial trial 12-week follow-up period. This study is registered with the European Union Drug Regulating Authorities Clinical Trials Database (EudraCT2016-004236-38) and the ISRCTN Registry (ISRCTN97503221). FINDINGS: Between March 20, 2017, and Sept 30, 2018, a total of 569 participants were randomly assigned. Of these, 564 (99%; intervention=280; control=284) were followed up for a median of 4·0 years (IQR 3·7-4·3). Participants had a mean age of 84·8 years (SD 3·4) at baseline and 273 (48%) were women. Medication reduction was sustained in 109 participants at follow-up (51% of the 213 participants alive in the intervention group). Participants in the intervention group had a larger reduction in antihypertensives than the control group (adjusted mean difference -0·35 drugs [95% CI -0·52 to -0·18]). Overall, 202 (72%) participants in the intervention group and 218 (77%) participants in the control group experienced hospitalisation or mortality during follow-up (adjusted hazard ratio [aHR] 0·93 [95% CI 0·76 to 1·12]). There was some evidence that the proportion of participants experiencing the primary outcome in the per-protocol population was lower in the intervention group (aHR 0·80 [0·64 to 1·00]). INTERPRETATION: Half of participants sustained medication reduction with no evidence of an increase in all-cause hospitalisation or mortality. These findings suggest that an antihypertensive deprescribing intervention might be safe for people aged 80 years or older with controlled blood pressure taking two or more antihypertensives.

In prior research related to physical activity, researchers have often centered their focus on only a limited number of activities, with little regard for mortality-related outcomes and insufficient focus on outcomes among diabetes patients with hypertension. The National Health and Nutrition Examination Survey was evaluated from 1999-2018 to identify individual with both diabetes and hypertension. These individuals were classified as being physically active or inactive. Comparisons among groups were performed with appropriate statistical tests. In total, this study evaluated data from 6,163 patients with a mean age of 63.18 ± 12.80 years. A total of 50.30% of the participants were male, with 39.86% being non-Hispanic white, 57.17% with a normal body mass index, and 89.20% were insured. Physical activity was significantly negatively correlated with systolic blood pressure in the overall population (p = 0.01) and when specifically focusing on individuals undergoing antihypertensive drug treatment (p = 0.0035). This negative relationship remained intact even following adjustment for age, sex, and ethnicity (p = 0.03). Physical activity was positively correlated with diastolic blood pressure in the overall population of participants (p = 0.002) and when specifically evaluating participants undergoing antihypertensive drug treatment (p = 0.02). All-cause and hypertensive mortality risk levels were significantly higher among individuals classified as being physically inactive (p < 0.0001), and this relationship remained true even with adjustment for age, sex, and ethnicity (p < 0.0001). In conclusion, physical activity is capable of lowering systolic blood pressure and decreasing the incidence of mortality among diabetes patients with hypertension.

BACKGROUND AND AIMS: Hypertension continues to be a major public health problem affecting almost half of the adults in the US. The intersection of hypertension with food insecurity has not been well-examined specifically among minority populations. We aimed to examine the influence of food insecurity on mortality among adult Hispanics. METHODS AND RESULTS: Data on adult Hispanic (age≥ 20 years) respondents of the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2010 were analyzed. Mortality was assessed by linking these data with the National Death Index through December 31, 2019. Using complex samples Cox regression analysis, the relationship between hypertension, food insecurity, and mortality was assessed. Sociodemographic (age, gender, poverty-income-ratio, marital status, and citizenship status) and health-related characteristics (COPD, diabetes, cardiovascular disease, chronic kidney disease) of the population were included as covariates in the regression analysis to assess mortality risk. The crude hazard ratio (HR) for overall mortality related to hypertension was 4.95 (95% confidence interval [CI] = 4.22-5.82, p < .001). The adjusted HR was elevated, 2.01 (95%CI = 1.50-2.70, p < .001), among individuals with both hypertension and food insecurity. However, among individuals with hypertension and no food insecurity, there was no statistically significant increase in the risk of mortality (HR = 1.09, 95%CI = 0.89-1.34, p > 0.05). CONCLUSIONS: In adult Hispanics, food insecurity significantly increases the risk of mortality among those with hypertension compared to food-secure individuals. Clinicians should be sensitized to the need for food security among Hispanics with hypertension to effectively manage hypertension and reduce premature mortality.

BACKGROUND: The association between baseline triglyceride glucose index (TyG index) and incident non-communicable diseases, mainly in Asian populations, has been reported. In the current study, we aimed to evaluate the association between index-year, average, and visit-to-visit variability (VVV) of the TyG index with incident type 2 diabetes mellitus (T2DM), hypertension, cardiovascular disease (CVD), and all-cause mortality among the Iranian population. METHODS: The study population included 5220 participants (2195 men) aged ≥ 30 years. TyG index was calculated as Ln (fasting triglycerides (mg/dL) × fasting plasma glucose (mg/dL)/2). Average values of the TyG index and also VVV (assessed by the standard deviation (SD) and variability independent of mean) were derived during the exposure period from 2002 to 2011 (index-year). Multivariable Cox proportional hazards regression models were used to estimate the hazard ratio (HR) and 95% confidence interval (CI) of the TyG index for incident different health outcomes. RESULTS: During more than 6 years of follow-up after the index year, 290, 560, 361, and 280 events of T2DM, hypertension, CVD, and all-cause mortality occurred. 1-SD increase in the TyG index values at the index-year was independently associated with the incident T2DM [HR (95% CI) 2.50 (2.13-2.93)]; the corresponding values for the average of TyG index were 2.37 (2.03-2.76), 1.12 (0.99-1.26, pvalue = 0.05), 1.18 (1.01-1.36), and 1.29 (1.08-1.53) for incident T2DM, hypertension, CVD, and all-cause mortality, respectively. Compared to the first tertile, tertile 3 of VVV of the TyG index was independently associated with incident hypertension [1.33 (1.07-1.64), Ptrend <0.01]. Likewise, a 1-SD increase in VVV of the TyG index was associated with an 11% excess risk of incident hypertension [1.11 (1.02-1.21)]. However, no association was found between the VVV of the TyG index and other outcomes. Moreover, the impact of index-year and average values of the TyG index was more prominent among women regarding incident CVD (P for interactions < 0.05). CONCLUSION: Although the higher TyG index at index-year and its VVV were only associated with the incident T2DM and hypertension, respectively, its average value was capable of capturing the risk for all of the health outcomes.
