Effectiveness of a Multifaceted Mobile Health Intervention (Multi-Aid-Package) in Medication Adherence and Treatment Outcomes Among Patients With Hypertension in a Low- to Middle-Income Country: Randomized Controlled Trial.

BACKGROUND: The high prevalence of uncontrolled hypertension in Pakistan is predominantly attributed to poor medication adherence. As more than 137 million people in Pakistan use cell phones, a suitable mobile health (mHealth) intervention can be an effective tool to overcome poor medication adherence. OBJECTIVE: We sought to determine whether a novel mHealth intervention is useful in enhancing antihypertensive therapy adherence and treatment outcomes among patients with hypertension in a low- to middle-income country. METHODS: A 6-month parallel, single-blinded, superiority randomized controlled trial recruited 439 patients with hypertension with poor adherence to antihypertensive therapy and access to smartphones. An innovative, multifaceted mHealth intervention (Multi-Aid-Package), based on the Health Belief Model and containing reminders (written, audio, visual), infographics, video clips, educational content, and 24/7 individual support, was developed for the intervention group; the control group received standard care. The primary outcome was self-reported medication adherence measured using the Self-Efficacy for Appropriate Medication Adherence Scale (SEAMS) and pill counting; the secondary outcome was systolic blood pressure (SBP) change. Both outcomes were evaluated at baseline and 6 months. Technology acceptance feedback was also assessed at the end of the study. A generalized estimating equation was used to control the covariates associated with the probability of affecting adherence to antihypertensive medication. RESULTS: Of 439 participants, 423 (96.4%) completed the study. At 6 months post intervention, the median SEAMS score was statistically significantly higher in the intervention group compared to the controls (median 32, IQR 11 vs median 21, IQR 6; U=10,490, P<.001). Within the intervention group, there was an increase in the median SEAMS score by 12.5 points between baseline and 6 months (median 19.5, IQR 5 vs median 32, IQR 11; P<.001). Results of the pill-counting method showed an increase in adherent patients in the intervention group compared to the controls (83/220, 37.2% vs 2/219, 0.9%; P<.001), as well as within the intervention group (difference of n=83, 37.2% of patients, baseline vs 6 months; P<.001). There was a statistically significant difference in the SBP of 7 mmHg between the intervention and control groups (P<.001) at 6 months, a 4 mmHg reduction (P<.001) within the intervention group, and a 3 mmHg increase (P=.314) within the controls. Overall, the number of patients with uncontrolled hypertension decreased by 46 in the intervention group (baseline vs 6 months), but the control group remained unchanged. The variables groups (adjusted odds ratio [AOR] 1.714, 95% CI 2.387-3.825), time (AOR 1.837, 95% CI 1.625-2.754), and age (AOR 1.618, 95% CI 0.225-1.699) significantly contributed (P<.001) to medication adherence. Multi-Aid-Package received a 94.8% acceptability score. CONCLUSIONS: The novel Multi-Aid-Package is an effective mHealth intervention for enhancing medication adherence and treatment outcomes among patients with hypertension in a low- to middle-income country.

The association between hepatitis C virus infection status and blood pressure in adults in the United States: NHANES 1999-2012.

Background: The Hepatitis C virus (HCV) infection is strongly associated with cardiovascular disease risk factors, but the relationship with blood pressure (BP) remains unclear. Objectives: To assess the association between HCV infection status and BP in US adults. Methods: Data for the study were obtained from the National Health and Nutrition Examination Survey (NHANES) between 1999 and 2012. The association of HCV infection status (including HCV infection, current HCV infection, and past HCV infection) with hypertension, systolic blood pressure (SBP), and diastolic blood pressure (DBP) were explored using logistic or linear regression analyses respectively. Results: A total of 25,850 participants (age≥18 years) were enrolled in the current study, including 14,162 participants with hypertension. After adjusting for all covariates, HCV infection/current HCV infection was not associated with hypertension and SBP compared to participants with non-HCV infection (OR: 1.34,95% CI 0.96-1.87/1.31 95% CI 0.91,1.91, ß: -0.92, 95% CI -2.7-0.86/-0.35 95% CI -2.51,1.81, respectively). HCV infection/current HCV infection was only associated with elevated DBP (ß: 4.1,95% CI 2.57-5.63/4.24,95% CI 2.27-6.21). However, there was no correlation with past HCV infection in participants with hypertension, SBP, and DBP compared to those with non-HCV infection (OR: 1.23,95% CI 0.59-2.54; ß: -3.79, 95% CI -7.67-0.08 and 2.28 95% CI -0.36-4.92, respectively). Conclusion: In a representative sample of US adults, it was found that both HCV infection and current HCV infection were independently linked to higher DBP. However, there was no association between past HCV infection and DBP.

Burden of diseases due to high systolic blood pressure in the Middle East and North Africa region from 1990 to 2019.

High systolic blood pressure (HSBP) is associated with several metabolic and non-metabolic disorders. This research aimed to document the deaths and disability-adjusted life-years (DALYs) attributable to HSBP in the Middle East and North Africa (MENA) region between 1990 and 2019, by age, sex, underlying cause and socio-demographic index (SDI). We used the methodological framework and data drawn from the Global Burden of Disease study 2019 to identify the burden of diseases attributable to HSBP, from 1990 to 2019, in the MENA region. The estimates reported were presented as counts, population-attributable fractions, and age-standardised rates (per 100,000), along with 95% uncertainty intervals. In 2019, 803.6 thousand (687.1 to 923.8) deaths were attributed to HSBP in MENA, which accounted for 25.9% (22.9-28.6%) of all deaths. The number of regional DALYs caused by HSBP in 2019 was 19.0 million (16.3-21.9 million), which accounted for 11.6% (10.1-13.3%) of all DALYs, and was 23.4% (15.9-31.5%) lower than in 1990. The highest age-standardised DALY rate for 2019 was observed in Afghanistan, with the lowest in Kuwait. Additionally, the DALY rate in MENA rose with age for both sexs. Furthermore, a negative linear relationship was found between SDI and the age-standardised DALY rates. The region has a substantial HSBP-related burden. Policymakers and healthcare professionals should prioritize interventions that effectively promote the early detection of HSBP, access to quality healthcare, and lifestyle modifications to mitigate the HSBP burden in the MENA countries.

Diastolic and systolic blood pressure and gout: a Mendelian randomization study.

Background: Although there is solid epidemiological evidence supporting the connection between hypertension and gout, little has been said about the relationship between diastolic and systolic blood pressure and gout, the causal relationship and direction associated are uncertain, so we aim to research the causal relationship between diastolic and systolic blood pressure and gout. Methods: We conducted a two-sample Mendelian randomization (MR) analysis to assess the causal effect between 2 blood pressure phenotypes (including diastolic blood pressure and systolic blood pressure) and 5 gout phenotypes (including gout, drug-induced gout, idiopathic gout, unspecified gout, and strictly defined gout) using genome-wide association study statistics. The inverse variance weighting method was used to generate the main results, while sensitivity analyses using MR-Egger, weighted median, Cochran's Q test, Egger intercept test, and leave-one-out analysis, were performed to assess the stability and reliability of the results. Results: After the screening, we found a causal relationship between diastolic blood pressure and gout, idiopathic gout, unspecified gout, and strictly defined gout, and a causal relationship between systolic blood pressure and gout, idiopathic gout, unspecified gout, and strictly defined gout. Conclusion: From a genetic predisposition, controlling blood pressure may reduce the risk of gout.

Pulse pressure modifies the association between diastolic blood pressure and decrease in kidney function: the Japan Specific Health Checkups Study.

Background: Unlike systolic blood pressure (SBP), the prognostic value of diastolic blood pressure (DBP) in kidney function has not been established. We hypothesized that pulse pressure (PP), which is associated with arteriosclerosis, would affect the prognostic value of DBP. Methods: This longitudinal study used data from the Japan Specific Health Checkups Study was conducted between 2008 and 2014. The participants were stratified into three PP subgroups (low PP ≤39, normal PP 40-59 and high PP ≥60 mmHg). The exposures of interest were SBP and DBP, and the association between SBP/DBP and kidney outcomes (30% decline in the estimated glomerular filtration rate from baseline) was examined in each PP subgroup using a Cox proportional hazards model. Results: Among 725 022 participants, 20 414 (2.8%) developed kidney outcomes during a median follow-up period of 34.6 months. Higher SBP was consistently associated with a higher incidence of kidney outcome in all PP subgroups. Although DBP had a positive linear association with the incidence of kidney outcome in low- and normal-PP subgroups, both lower (≤60 mmHg) and higher (≥101 mmHg) DBP were associated with a higher incidence of kidney outcome in the high-PP subgroup, with a U-shaped curve. Hazard ratios (95% confidence intervals) of ≤60 mmHg (reference: 61-80 mmHg in normal-PP subgroup) and ≥101 mmHg were 1.26 (1.15-1.38) and 1.86 (1.62-2.14), respectively. Conclusions: In this large population-based cohort, DBP was differently associated with kidney outcome by PP level; lower DBP was significantly associated with a higher incidence of kidney outcome in the high-PP subgroup but not in the low- and normal-PP subgroups.

Ambulatory Blood Pressure Parameters Among Men With Hypogonadism Treated With Testosterone Transdermal Therapy.

OBJECTIVE: Studies are needed to examine the effects of testosterone replacement therapy (TRT) on ambulatory blood pressure (BP) parameters. This study assessed a testosterone transdermal system (TTS) using 24-hour ambulatory BP monitoring (ABPM). METHODS: In a single-arm, noninferiority trial conducted at 41 US sites, 168 men (mean age: 56.2 years) with hypogonadism not receiving TRT in the past 6 months were enrolled and received ≥1 study drug dose. Nightly TTS treatment was administered for 16 weeks (starting dose: 4 mg/d; min, max dose: 2, 6 mg/d) to achieve testosterone concentration of 400-930 ng/dL. The primary endpoint was mean change from baseline to week 16 in 24-hour systolic BP (SBP). Noninferiority was determined based on the upper bound of the 2-sided 95% CI <3.0 mmHg. RESULTS: 62 men had ≥85% study drug compliance and a valid week 16 ABPM session. Mean change from baseline to week 16 in 24-hour average SBP was 3.5 mmHg (95% CI, 1.2-5.8 mmHg; n=62). Since the upper limit of the CI was >3 mmHg, an effect of TTS could not be ruled out. Mean changes were larger at daytime vs nighttime and in subgroups of men with vs without hypertension. Cardiovascular adverse events (AEs) were rare (<2%) and nonserious; no major cardiovascular AEs were reported. CONCLUSION: A meaningful effect of 16-week TTS treatment on 24-hour average SBP among men with hypogonadism could not be ruled out based on the study's noninferiority criterion. The magnitude of mean changes observed may not be clinically meaningful regarding cardiovascular events.

Adherence to 24-Hour Movement Guidelines Among Chinese Older Adults: Prevalence, Correlates, and Associations With Physical and Mental Health Outcomes.

BACKGROUND: It is known that 24-hour movement behaviors, including physical activity (PA), sedentary behavior (SB), and sleep, are crucial components affecting older adults' health. Canadian 24-hour movement guidelines for older adults were launched in 2020, emphasizing the combined role of these 3 movement behaviors in promoting older adults' health. However, research on the prevalence and correlates of guideline adherence and its associations with health-related outcomes is limited, especially among Chinese older adults. OBJECTIVE: This study aimed to investigate the prevalence and correlates of meeting 24-hour movement guidelines among Chinese older adults. Furthermore, this study aimed to examine the associations of guideline adherence with older adults' physical and mental health outcomes. METHODS: Using a stratified cluster random sampling approach, a total of 4562 older adults (mean age 67.68 years, SD 5.03 years; female proportion: 2544/4562, 55.8%) were recruited from the latest provincial health surveillance of Hubei China from July 25 to November 19, 2020. Measures included demographics, movement behaviors (PA, SB, and sleep), BMI, waist circumference, waist-hip ratio (WHR), percentage body fat (PBF), systolic and diastolic blood pressure, physical fitness, depressive symptoms, and loneliness. Generalized linear mixed models were employed to examine the associations between variables using SPSS 28.0 (IBM Corp). RESULTS: Only 1.8% (83/4562) of participants met all 3 movement guidelines, while 32.1% (1466/4562), 3.4% (155/4562), and 66.4% (3031/4562) met the individual behavioral guidelines for PA, SB, and sleep, respectively. Participants who were older, were female, and lived in municipalities with lower economic levels were less likely to meet all 3 movement guidelines. Adhering to individual or combined movement guidelines was associated with greater physical fitness and lower values of BMI, waist circumference, WHR, PBF, depressive symptoms, and loneliness, with the exception of the relationship of SB+sleep guidelines with loneliness. Furthermore, only meeting SB guidelines or meeting both PA and SB guidelines was associated with lower systolic blood pressure. CONCLUSIONS: This is the first study to investigate adherence to 24-hour movement guidelines among Chinese older adults with regard to prevalence, correlates, and associations with physical and mental health outcomes. The findings emphasize the urgent need for promoting healthy movement behaviors among Chinese older adults. Future interventions to improve older adults' physical and mental health should involve enhancing their overall movement behaviors and should consider demographic differences.

Obesity and Risk of Incident Left Ventricular Hypertrophy in Community-Dwelling Populations With Hypertension: An Observational Study.

BACKGROUND: The aim of this study was to evaluate the association between obesity and risk of incident left ventricular hypertrophy (LVH) in community-dwelling populations with hypertension and investigate whether this association would be attenuated by a lower achieved systolic blood pressure (SBP). METHODS AND RESULTS: We used the EMINCA (Echocardiographic Measurements in Normal Chinese Adults) criteria, which were derived from healthy Chinese populations to define LVH. A total of 2069 participants with hypertension and without LVH (obesity 20.4%) were included. The association between obesity and risk of incident LVH was evaluated using Cox proportional hazard models and stratified by achieved follow-up SBP levels (≥140, 130-139, and <130 mm Hg). These analyses were also assessed using the American Society of Echocardiography/European Association of Cardiovascular Imaging criteria, which were derived from European populations to define LVH. After a median follow-up of 2.90 years, the rates of incident LVH in the normal-weight, overweight, and obese groups were 13.5%, 20.3%, and 27.8%, respectively (P<0.001). In reference to normal weight, obesity was associated with increased risk of incident LVH (adjusted hazard ratio [aHR], 2.51 [95% CI, 1.91-3.29]), which was attenuated when achieved SBP was <130 mm Hg (aHR, 1.78 [95% CI, 0.99-3.19]). This association remained significant when achieved SBP was ≥140 mm Hg (aHR, 3.45 [95% CI, 2.13-5.58]) or at 130 to 139 mm Hg (aHR, 2.32 [95% CI, 1.23-4.36]). Differences in these findings were noted when LVH was defined by the American Society of Echocardiography/European Association of Cardiovascular Imaging criteria. CONCLUSIONS: Obesity was associated with incident LVH and an SBP target <130 mm Hg might be needed to attenuate this risk in patients with hypertension and obesity.

Association of cardiovascular events with central systolic blood pressure: A systemic review and meta-analysis.

Central blood pressure confers cardiovascular risk prediction ability, but whether the association between central systolic blood pressure (cSBP) and cardiovascular endpoints is independent of peripheral systolic blood pressure (pSBP) remains controversial. This systematic review and meta-analysis aim to investigate the associations between cSBP and cardiovascular endpoints in models including and excluding pSBP, respectively. Observational studies assessing the risk of composite cardiovascular endpoints with baseline cSBP were searched in PubMed, Embase, Scopus, Web of Science, and Cochrane Library to May 31, 2022. Risk of bias was assessed by the Newcastle-Ottawa Quality Assessment Scale, and random-effects models were used to pool estimates. Finally, 48 200 participants from 19 studies with a mean age of 59.0 ± 6.9 years were included. Per 10 mmHg increase of cSBP was associated with higher risk of composite cardiovascular outcomes (risk ratio [RR]: 1.14 [95%CI 1.08-1.19]) and cardiovascular death (RR: 1.18 [95%CI 1.08-1.30]), and the associations still existed after adjusting for pSBP (RR: 1.13 [95%CI 1.05-1.21] for composite cardiovascular endpoints; RR: 1.25 [95%CI 1.09-1.43] for cardiovascular death). In pSBP-unadjusted studies, increased cSBP was also associated with higher risk of all-cause mortality and stroke, but not in the pSBP-adjusted studies. Both cSBP and pSBP were similarly significantly associated with composite cardiovascular endpoints in models containing them separately and simultaneously. cSBP was significantly associated with cardiovascular events, independently of pSBP. Central or peripheral SBP could supplement cardiovascular risk assessment besides each other.

Obesity and risk of hypertension in preadolescent urban school children: insights from Pakistan.

BACKGROUND: Childhood obesity and hypertension are growing concerns globally, especially in developing countries. This study investigated the association between overall and central obesity at baseline, and prehypertension or hypertension at follow-up among preadolescent school children in urban Karachi, Pakistan. METHODS: This is a sub study with cohort design embedded within a feasibility trial on School Health Education Program in Pakistan (SHEPP) in preadolescents aged 6-11 years, attending two private schools conducted from 2017 to 2019. Hypertension or prehypertension at follow-up were the outcomes and obesity or central obesity at baseline were the exposure variables. Hypertension was defined as systolic blood pressure and/or diastolic blood pressure ≥ 95th percentile for age, sex, and height. Obesity was defined as body mass index for-age and sex ≥ 95th percentile, whereas central obesity was determined by waist circumference measurements ≥ 85th percentile of age, sex, and height specific cut-offs. Logistic regression analysis was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) to identify risk factors for hypertension and prehypertension. RESULTS: Analysis was conducted for 908 participants, evenly distributed with 454 boys and 454 girls. Hypertension was observed in 19.8% of the preadolescents, with rates of 18.5% in boys and 21.0% in girls. Prehypertension was found in 16.8% of preadolescents, with 18% among boys and 16% among girls. Additionally, 12.8% of preadolescents were classified as obese and 29.8% had central obesity. Obesity at baseline was associated with hypertension at followup (OR 8.7, 95% CI 3.5, 20.4) in the final model after adjusting for age, gender, physical activity, sedentary behavior, fruits, vegetable intake and hypertension at baseline. Central obesity at baseline also yielded high odds, with prehypertension (OR 1.9, 95% CI 1.4, 2.8) and hypertension (OR 2.7, 95% CI 1.9, 3.9) at follow up in the final model. CONCLUSION: This study highlights a concerning prevalence of hypertension and prehypertension among preadolescent school-going children. Obesity and central obesity at baseline emerged as significant predictive factors for hypertension or prehypertension at followup within this cohort. The findings emphasize the urgency of implementing comprehensive school health education programs aimed at early detection and effective management of hypertension during childhood and adolescence in school settings.

Engagement in mHealth-Prompted Self-Measured Blood Pressure Monitoring Among Participants Recruited From a Safety-Net Emergency Department: Secondary Analysis of the Reach Out Trial.

Background: Hypertension, a key modifiable risk factor for cardiovascular disease, is more prevalent among Black and low-income individuals. To address this health disparity, leveraging safety-net emergency departments for scalable mobile health (mHealth) interventions, specifically using text messaging for self-measured blood pressure (SMBP) monitoring, presents a promising strategy. This study investigates patterns of engagement, associated factors, and the impact of engagement on lowering blood pressure (BP) in an underserved population. Objective: We aimed to identify patterns of engagement with prompted SMBP monitoring with feedback, factors associated with engagement, and the association of engagement with lowered BP. Methods: This is a secondary analysis of data from Reach Out, an mHealth, factorial trial among 488 hypertensive patients recruited from a safety-net emergency department in Flint, Michigan. Reach Out participants were randomized to weekly or daily text message prompts to measure their BP and text in their responses. Engagement was defined as a BP response to the prompt. The k-means clustering algorithm and visualization were used to determine the pattern of SMBP engagement by SMBP prompt frequency-weekly or daily. BP was remotely measured at 12 months. For each prompt frequency group, logistic regression models were used to assess the univariate association of demographics, access to care, and comorbidities with high engagement. We then used linear mixed-effects models to explore the association between engagement and systolic BP at 12 months, estimated using average marginal effects. Results: For both SMBP prompt groups, the optimal number of engagement clusters was 2, which we defined as high and low engagement. Of the 241 weekly participants, 189 (78.4%) were low (response rate: mean 20%, SD 23.4) engagers, and 52 (21.6%) were high (response rate: mean 86%, SD 14.7) engagers. Of the 247 daily participants, 221 (89.5%) were low engagers (response rate: mean 9%, SD 12.2), and 26 (10.5%) were high (response rate: mean 67%, SD 8.7) engagers. Among weekly participants, those who were older (>65 years of age), attended some college (vs no college), married or lived with someone, had Medicare (vs Medicaid), were under the care of a primary care doctor, and took antihypertensive medication in the last 6 months had higher odds of high engagement. Participants who lacked transportation to appointments had lower odds of high engagement. In both prompt frequency groups, participants who were high engagers had a greater decline in BP compared to low engagers. Conclusions: Participants randomized to weekly SMBP monitoring prompts responded more frequently overall and were more likely to be classed as high engagers compared to participants who received daily prompts. High engagement was associated with a larger decrease in BP. New strategies to encourage engagement are needed for participants with lower access to care.

Association between long-term visit-to-visit blood pressure variability and depression among Chinese middle-aged and older adults.

BACKGROUND: Whether there is a longitudinal association between long-term blood pressure variability (BPV) and subsequent depression among Chinese adults remains inconclusive. METHODS: This study utilized data from a nationwide cohort of the China Health and Retirement Longitudinal Study, which included participants aged > 45 years without prevalent psychiatric or memory-related diseases. The intra-individual coefficient of variation (CV) and standard deviation (SD) across 3 visits from 2011 to 2015 were used to examine the long-term variability in systolic BP (SBP) and diastolic BP (DBP). The depressive symptoms were examined using the 10-item Center for Epidemiologic Studies Depression Scale (CES-D-10), and moderate-to-severe depression was defined as CES-D-10 ≥ 15. RESULTS: A total of 5,249 participants (mean age: 61.4 ± 8.1 years, 46.5% were men) were included in the current analysis. Individuals in the highest quartile of both BP CV and SD were independently correlated with a higher total CES-D-10 score compared to those in the lowest quartile after multivariable adjustment. 1,070 participants (20.4%) had moderate-to-severe depression during the 3-year follow-up period. Participants in the Q4 of SBP and DBP CV had 1.23-fold higher odds (95% CI: 1.01, 1.49) and 1.20-fold higher odds (95% CI: 1.01, 1.41) of moderate-to-severe depression compared to those in Q1. Subgroup analyses revealed that men with higher BP CVs had a greater risk of severe depressive symptoms (p for SBP CV-by-sex interaction = 0.050, p for SBP CV-by-sex interaction = 0.025). CONCLUSIONS: Depression was common among Chinese middle-aged and older adults and long-term visit-to-visit BPV was positively associated with depressive symptoms, highlighting the importance of implementing intensive prevention strategies for depression and enhancing blood pressure monitors in China.

Hesperidin reduces systolic blood pressure in diabetic patients and has no effect on blood pressure in healthy individuals: A systematic review and meta-analysis.

In recent years, there have been a number of studies where hesperidin was administered to modify arterial blood pressure, but the conclusions of each study are contradictory. In order to investigate the effect of hesperidin on blood pressure, we searched the CNKI, Wanfang Database, the VIP database, Sinomed database, Pubmed, Embase and The Cochrane Library databases, and searched the literature on hesperidin and blood pressure published in Chinese and English journals, mainly focusing on patients' systolic blood pressure and diastolic blood pressure. The search time frame was from the inception of the databases until December 2023. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the overall quality and used Cohen's kappa coefficient (κ) to measure agreement. We did preliminary screening of the retrieved literature through Notexpress, 14 articles with a total of 656 patients were included. Cochrance data conversion tool was used for data conversion, and RevMan 5.3 was used for meta-analysis, and finally Stata was used to make the Egger's test for the included study. The results of total population blood pressure showed that hesperidin had no antihypertensive effect on the population, but the conclusions changed when the population was divided into groups. The results of different populations showed that hesperidin had no effect on systolic blood pressure (weighted mean difference [WMD] = -0.50, 95% CI: -3.25 ~ 2.26, Z = 0.35, p = 0.72) and diastolic blood pressure (WMD = -0.51, 95% CI: -2.53 ~ 1.51, Z = 0.50, p = 0.62) in healthy individuals. However, hesperidin reduced systolic blood pressure in patients with type 2 diabetes (WMD = -4.32, 95% CI: - 7.77 ~ - 0.87, Z = 2.45, p = 0.01), and had a tendency to reduce diastolic blood pressure in diabetic patients (WMD = -3.72, 95% CI: -7.63 ~ 0.18, Z = 1.87, p = 0.06). The results in patients with type 2 diabetes needed to be further supported by future research focusing on individuals with diabetes.

High body mass index and triglyceride levels at health checkups increase the risk of new-onset chronic kidney disease and worsening renal function: the TAMA MED Project-CKD.

BACKGROUND: Health checkups are important in patients with chronic kidney disease (CKD), which is not easily accompanied by subjective symptoms. CKD can be caused or aggravated by factors that have not yet been identified. METHODS: This retrospective cohort study included 7 483 patients who underwent specific annual health checkups at a medical institution in Tama City, did not have CKD in 2012, and continued to undergo checkups (aged 40-74 years). We examined the risk factors for new-onset CKD and 1.5-fold increase in serum creatinine levels among laboratory values from 2012 to 2020. RESULTS: Age, body mass index (BMI), triglyceride levels, atrial fibrillation, and medication for hypertension (HT) and diabetes mellitus were independent risk factors for proteinuria, whereas current smoking, BMI, systolic blood pressure (SBP), and medication for HT were independent risk factors for estimated glomerular filtration rate < 60 mL/min/1.73 m2. SBP, triglyceride levels and medication for HT were risk factors for a 1.5-fold increase in serum creatinine levels during course of the study. The cut-off values of BMI for eGFR < 60 mL/min/1.73 m2 were 22.2 (men 24.7, women 22.1) kg/m2 and fasting triglyceride levels for a 1.5-fold increase in serum creatinine level were 171 (men 247, women 170) mg/dL, respectively. CONCLUSIONS: Health checkups provide information to prevent new-onset CKD and worsening of renal function. It is necessary to increase the rate of health checkups and visits to medical institutions after health checkups as well as to use these results for health guidance.

Endogenous estrogen exposure and hypertension risk; a population-based cohort study with about two decades of follow-up.

CONTENT: The impact of endogenous estrogen exposure (EEE) on hypertension (HTN) incidence has not been investigated yet. OBJECTIVE: This study aimed to evaluate HTN incidence in women with different endogenous estrogen durations. METHODS: Information was gathered from the Tehran Lipid and Glucose Study (TLGS) to conduct current research. At the initiation of the study, 4463 post-menarche normotensive women, including 3599 premenopausal and 864 menopausal women, were included. EEE was calculated for each woman, and they were followed up for the HTN event. According to the EEE, the hazard ratios and 95% confidence intervals (CI) for the HTN event were presented using Cox proportional hazards regression models (unadjusted and adjusted). RESULTS: The median (interquartile range) of follow-up (between menarche and the date of HTN incidence or last follow-up) was 33.2(25.1, 42.3) years. The event of menopause occurred in 31.8% of participants. The unadjusted model's findings illustrated that the EEE z-score was inversely associated with HTN incidence in post-menarcheal women [unadjusted hazard ratio (HR) 0.47, 95% CI 0.44, 0.50], meaning that the risk of HTN decreased by 53% for every 1-SD rise in the EEE z-score. After adjusting for potential confounders, the results showed no statistically significant changes (adjusted HR 0.46, 95% CI 0.43-0.49). In participants with prehypertension at baseline, the hazard of HTN decreased by 56% per 1-SD rise in the EEE z-score. CONCLUSION: This longitudinal study demonstrated the protective effect of a longer EEE duration on HTN risk, even among those with prehypertension status.

Effects of high-intensity interval exercise on arterial stiffness in individuals at risk for cardiovascular disease: a meta-analysis.

Objective: The purpose of this meta-analysis was to investigate the effect of high-intensity interval training (HIIT) on arterial stiffness (AS) and vascular function in persons at high risk of cardiovascular disease (CVD). Methods: We conducted a comprehensive search of randomized controlled trials (RCTs) published in electronic databases (PubMed, Web of Science, Cochrane, Embase, and Ebsco) since their inception through October 2023 to evaluate the effect of HIIT on AS and vascular function in persons at high risk for CVD. The weighted mean difference (WMD) and 95% confidence intervals (95% CI) were calculated, and heterogeneity was assessed using the I2 test. Results: This study included 661 participants from 16 studies. HIIT significantly reduced pulse wave velocity (PWV) in persons at high risk for CVD [weighted mean difference (WMD), -0.62; 95% CI, -0.86--0.38; P < 0.00001]. Subgroup analysis showed that the PWV improvement effect was better when the HIIT program was performed 2-3 times per week and the duration was controlled within 40 min [2-3 times, -0.67; 95% CI, -0.93--0.41; P < 0.00001; time of duration, ≤40 min, -0.66; 95% CI, -0.91--0.41; P < 0.00001]. HIIT significantly reduced systolic blood pressure (SBP, -5.43; 95% CI, -8.82--2.04; P = 0.002), diastolic blood pressure (DPB, -2.96; 95% CI, -4.88--1.04; P = 0.002), and resting heart rate (RHR, -4.35; 95% CI, -7.04--1.66; P = 0.002), but had no significant effect on augmentation index (AIX, -2.14; 95% CI, -6.77-2.50; P = 0.37). Conclusion: HIIT can improve PWV in high-risk individuals with CVD and reduce SBP, DBP, and RHR, but has no significant effect on AIX. HIIT can effectively improve AS and vascular function and can be recommended as an effective method to improve AS in high-risk persons with CVD.

Association of Sacubitril/Valsartan versus Valsartan with Blood Pressure Changes, and Symptomatic Hypotension: The PARAGLIDE-HF Trial.

BACKGROUND: In PARAGLIDE-HF, among patients with ejection fraction (EF) >40%, stabilized after worsening heart failure (WHF), sacubitril/valsartan led to greater reduction in plasma NT-proBNP levels and was associated with clinical benefit compared to valsartan alone, despite more symptomatic hypotension (SH). Concern over SH may be limiting use of sacubitril/valsartan in appropriate patients. METHODS: We characterized patients by the occurrence of SH (investigator-reported) after randomization to either sacubitril/valsartan or valsartan. A key trial inclusion criterion was systolic blood pressure (SBP) ≥100 mmHg for the preceding 6 hours and no SH. We also compared outcomes based on baseline SBP stratified by the median blood pressure. The primary endpoint was time-averaged proportional change in NT-proBNP from baseline through Weeks 4 and 8. A secondary hierarchical outcome (win ratio) consisted of: a) cardiovascular death, b) HF hospitalizations, c) urgent HF visits, and d) change in NT-proBNP. RESULTS: Among 466 randomized patients, 92 (19.7%) experienced SH (sacubitril/valsartan, N=56 [24.0%]; valsartan, N=36 [15.5%], p=0.020). The median time to the first SH event was similar between treatment arms (18 days vs. 15 days, respectively, p=0.42) as was the proportion of first SH events classified as "serious" by investigators. Patients who experienced SH with sacubitril/valsartan were more likely to be White (OR 1.87 [95%CI: 0.31, 11.15]), to have a lower baseline SBP (per 10mmHg increase OR 0.68 [95%CI: 0.55, 0.85]), or to have a left ventricular ejection fraction (LVEF) of >60% (OR 2.21 [95%CI: 1.05, 4.65]). Time-averaged change in NT-proBNP did not differ between patients with baseline SBP ≥128 mmHg vs. SBP<128mmHg (interaction p=0.43). The composite hierarchical outcome for sacubitril/valsartan in patients with baseline SBP≥128mmHg had a win ratio of 1.34 ([95%CI: 0.91, 1.99], p=0.096) vs SBP<128mmHg with a win ratio of 1.09 ([95%CI: 0.73, 1.66], p=0.62; interaction p value=0.42). CONCLUSION: Among patients with LVEF>40% stabilized after WHF, incident SH was more common with sacubitril/valsartan compared with valsartan. SH was associated with lower baseline SBP, White race, and higher LVEF. Treatment benefits with sacubitril/valsartan may be more pronounced in patients with higher baseline SBP and lower LVEF (≤ 60%).

Systolic blood pressure and risk of cardiovascular disease in normotensive diabetic adults: a prospective cohort study.

BACKGROUND: Currently, the special blood pressure (BP) target for normotensive diabetic patients has not been recommended. We investigated the optimal systolic blood pressure (SBP) for lower cardiovascular disease (CVD) risk in normotensive diabetic patients. METHODS: In this 12-year follow-up study using the participants of the Kailuan Study, we mainly compared which SBP, 90-119 mmHg or 120-129 mmHg, had a lower risk of occurrence of CVD (stroke and myocardial infarction) in the 3072 normotensive diabetic participants and 21,532 normotensive and non-diabetic participants, respectively. The SBP was expressed as a mean time-weighted cumulative (MTWC) SBP, calculated from the multiple measurements of SBP during the follow-up. Multivariate competing risk regression analyses were used for the analysis. RESULTS: We found that in normotensive diabetic participants, MTWC SBP of 120-129 mmHg was associated with a lower risk of CVD (HR = 0.69 [0.50-0.95]), myocardial infarction (HR = 0.48 [0.24-0.96]), and trending towards lower risk of stroke (HR = 0.80 [0.55-1.16]), compared to MTWC SBP of 90-119 mmHg. Sensitivity analyses confirmed the relationship between low SBP and increased CVD risk. Whereas, in the normotensive and non-diabetic participants, MTWC SBP of 90-119 mmHg vs 120-129 mmHg did not exhibit any difference in the risk of CVD occurrence (HR = 0.99 [0.83-1.18]). CONCLUSIONS: The higher level of SBP in normotensive diabetic patients is especially associated with a lower risk of CVD occurrence.

Associations between anxiety, sleep, and blood pressure parameters in pregnancy: a prospective pilot cohort study.

BACKGROUND: The potential effect modification of sleep on the relationship between anxiety and elevated blood pressure (BP) in pregnancy is understudied. We evaluated the relationship between anxiety, insomnia, and short sleep duration, as well as any interaction effects between these variables, on BP during pregnancy. METHODS: This was a prospective pilot cohort of pregnant people between 23 to 36 weeks' gestation at a single institution between 2021 and 2022. Standardized questionnaires were used to measure clinical insomnia and anxiety. Objective sleep duration was measured using a wrist-worn actigraphy device. Primary outcomes were systolic (SBP), diastolic (DBP), and mean (MAP) non-invasive BP measurements. Separate sequential multivariable linear regression models fit with generalized estimating equations (GEE) were used to separately assess associations between anxiety (independent variable) and each BP parameter (dependent variables), after adjusting for potential confounders (Model 1). Additional analyses were conducted adding insomnia and the interaction between anxiety and insomnia as independent variables (Model 2), and adding short sleep duration and the interaction between anxiety and short sleep duration as independent variables (Model 3), to evaluate any moderating effects on BP parameters. RESULTS: Among the 60 participants who completed the study, 15 (25%) screened positive for anxiety, 11 (18%) had subjective insomnia, and 34 (59%) had objective short sleep duration. In Model 1, increased anxiety was not associated with increases in any BP parameters. When subjective insomnia was included in Model 2, increased DBP and MAP was significantly associated with anxiety (DBP: ß 6.1, p = 0.01, MAP: ß 6.2 p < 0.01). When short sleep was included in Model 3, all BP parameters were significantly associated with anxiety (SBP: ß 9.6, p = 0.01, DBP: ß 8.1, p < 0.001, and MAP: ß 8.8, p < 0.001). No moderating effects were detected between insomnia and anxiety (p interactions: SBP 0.80, DBP 0.60, MAP 0.32) or between short sleep duration and anxiety (p interactions: SBP 0.12, DBP 0.24, MAP 0.13) on BP. CONCLUSIONS: When including either subjective insomnia or objective short sleep duration, pregnant people with anxiety had 5.1-9.6 mmHg higher SBP, 6.1-8.1 mmHg higher DBP, and 6.2-8.8 mmHg higher MAP than people without anxiety.

Global burden of stroke attributable to high systolic blood pressure in 204 countries and territories, 1990-2019.

Background: High systolic blood pressure (HSBP) is severely related to stroke, although the global burden of stroke associated with HSBP needs to be understood. Materials and methods: Data derived from the Global Burden of Disease, Injuries, and Risk Factors Study were used to analyze deaths, disability-adjusted life years (DALYs), age-standardized rates of mortality (ASMR), age-standardized rates of DALY (ASDR), and estimated annual percentage change (EAPC). Results: Globally, 52.57% of deaths and 55.54% of DALYs from stroke were attributable to HSBP in 2019, with higher levels in men; the ASMRs and ASDRs in 1990-2019 experienced a decline of 34.89% and 31.71%, respectively, with the highest ASMR- and ASDR-related EAPCs in women. The middle socio-demographic index (SDI) regions showed the most numbers of deaths and DALYs in 2019 and 1990, with a decline in ASMR and ASDR; East Asia shared over 33% of global deaths and DALYs; Central Asia shared the highest ASMR and ASDR; high-income Asia Pacific experienced the highest decline in the ASMR- and ASDR-related EAPCs. Central and Southeast Asia had the highest percentages for deaths and DALYs, respectively, with more ASMR in high-middle SDI; the SDI and human development index were negatively associated with ASMR/ASDR and ASMR/ASDR-related EAPCs in 2019. Conclusion: Global deaths and DALYs of stroke attributable to HSBP but none of their age-standardized rates have been on the rise over the past three decades; its disease burden focused especially on men aged 70 years and older in East, Central, and Southeast Asia, and the middle to high SDI regions.
