Simple risk scoring using sinus rhythm electrocardiograms predicts the incidence of atrial fibrillation in the general population.

Atrial fibrillation (AF) is an arrhythmic disease. Prediction of AF development in healthy individuals is important before serious complications occur. We aimed to develop a risk prediction score for future AF using participants' data, including electrocardiogram (ECG) measurements and information such as age and sex. We included 88,907 Japanese participants, aged 30-69 years, who were randomly assigned to derivation and validation cohorts in a ratio of 1:1. We performed multivariate logistic regression analysis and obtained the standardised beta coefficient of relevant factors and assigned scores to them. We created a score based on prognostic factors for AF to predict its occurrence after five years and applied it to validation cohorts to assess its reproducibility. The risk score ranged from 0 to 17, consisting of age, sex, PR prolongation, QT corrected for heart rate prolongation, left ventricular hypertrophy, premature atrial contraction, and left axis deviation. The area under the curve was 0.75 for the derivation cohort and 0.73 for the validation cohort. The incidence of new-onset AF reached over 2% at 10 points of the risk score in both cohorts. Thus, in this study, we showed the possibility of predicting new-onset AF using ECG findings and simple information.

Associations of eating out and dietary diversity with mild cognitive impairment among in community-dwelling older adults.

Background: Dementia is a critical later life health issue that occurs among members of aging societies. This study examined the relationships between eating out, dietary diversity, and mild cognitive impairment (MCI) among community-dwelling older adults. Methods: We analyzed data from 597 older adults (median age 73.0 years [interquartile range 69.0-78.0] and 62.6% females). We applied the Food Frequency Score (FFS) to evaluate diet variety and the weekly consumption frequencies of ten food items were determined. The Functional Assessment Tool from the National Center for Geriatrics and Gerontology was used to evaluate MCI. Finally, we asked the participants how often they ate out each month; those who replied 'none' were categorized into the "non-eating out" group. Results: The overall prevalence of MCI was 122 (20.4%), with a higher prevalence in the low dietary diversity group than in the high dietary diversity group (28.6% vs. 18.6%). After adjusting for covariates, the participants who self-described as not eating out were independently associated with low dietary diversity (odds ratio [OR]: 1.97, 95% confidence interval [CI]: 1.20-3.20), while low dietary diversity was associated with MCI (OR: 1.72, 95% CI: 1.02-2.87). Structural equation models revealed that not eating out had no direct effect on MCI but was associated with MCI via low dietary diversity (root mean square error of approximation = 0.030, goodness-of-fit index=0.999, and adjusted goodness-of-fit index = 0.984). Conclusions: Although non-eating out may not have a direct effect on MCI, an indirect relationship may exist between eating-out habits and MCI via dietary diversity status.

Independent Association between Cognitive Frailty and Cardio-Ankle Vascular Index in Community-Dwelling Older Adults.

INTRODUCTION: Although arterial stiffness has been suggested to be associated with poor physical function and mild cognitive impairment (MCI), its association with cognitive frailty (CF), a comorbidity of both, is unclear. This study aims to examine the association between CF and arterial stiffness in community-dwelling older adults. METHODS: A cross-sectional analysis of 511 community-dwelling older adults aged 65 years or older (mean age 73.6 ± 6.2 years, 63.6% women), who participated in a community cohort study (Tarumizu Study, 2019), was conducted. Poor physical function was defined as either slowness (walking speed <1.0 m/s) or weakness (grip strength <28 kg for men and <18 kg for women). MCI was defined by the National Center for Geriatrics and Gerontology Functional Assessment Tool as a decline of at least 1.5 standard deviation from age- and education-adjusted baseline values in any one of the four cognitive domains (memory, attention, executive, and information processing). CF was defined as the combination of poor physical function and MCI. Arterial stiffness was measured using the Cardio-Ankle Vascular Index (CAVI), and the average of the left and right sides (mean CAVI) was used. RESULTS: Multinomial logistic regression analysis adjusted for covariates was performed with the four groups of robust, poor physical function, MCI, and CF as dependent variables and mean CAVI as an independent variable. Using the robust group as reference, the poor physical function and MCI groups showed no significant relationship with the mean CAVI. The mean CAVI was significantly higher in the CF group (odds ratio 1.62, 95% confidence interval: 1.14-2.29). CONCLUSION: A significant association was found between CF and the higher CAVI (progression of arterial stiffness). Careful observation and control of CAVI, which is also an indicator of arterial stiffness, may be a potential target for preventive interventions for CF.

Association between weight gain following smoking cessation and development of hypertension in the future.

Although quitting smoking lowers the risk of developing chronic conditions, it usually leads to weight gain. Literature on the association between weight gain after quitting smoking and the future development of hypertension is scarce. Among 234 596 individuals who visited our health center, 856 who had quit smoking for whom data were available at least 6 years after smoking cessation were included. We evaluated changes in blood pressure and antihypertensive drug prescription rate at 1 and 6 years after smoking cessation. We also compared weight and blood pressure between the smoking cessation and continued smoking groups after 6 years. Multiple regression analyses were performed to identify predictors of changes in systolic and diastolic blood pressures using covariates affecting blood pressure. Since a median weight gain of 1.8 kg was observed at 1 year after smoking cessation, we divided the participants into high and low-weight gain groups. No significant intergroup difference in the antihypertensive drug prescription rate was observed after 6 years. The high weight gain group showed significant increases in systolic and diastolic blood pressures after 6 years. Multiple regression analyses revealed that systolic blood pressure was affected by age and high weight gain, while diastolic blood pressure was affected by high weight gain. Our findings suggest that weight gain following smoking cessation leads to blood pressure elevation: the smoking cessation group gained more weight and had higher blood pressure than the continued smoking group. Therefore, weight loss guidance may be useful for individuals who want to quit smoking. Participants in the high weight gain group showed significant increases in systolic and diastolic blood pressures at 6 years after smoking cessation that were significantly different from those observed in participants in the low weight gain group and the continued smoking group.

Relationship between defecation status and blood pressure level or blood pressure variability.

Blood pressure variability is an independent predictor of cardiovascular disease. Defecation status has also been associated with the risk of developing cardiovascular disease. This study aimed to investigate the association between blood pressure variability and defecation status. A total of 184 participants who could measure their home blood pressure for at least 8 days monthly, both at baseline and 1 year later, were included in this study. All participants had their home blood pressure measured using HEM-9700T (OMRON Healthcare). Day-to-day variability of systolic blood pressure was assessed using the coefficient of variation of home systolic blood pressure during 1 month. Data on defecation status was obtained using a questionnaire survey. Eighty-nine patients had an elevated coefficient of variation at 1 year. The proportion of participants with elevated coefficient of variation at 1 year was significantly higher in the no daily bowel movement group than in the daily bowel movement group (72% vs. 42%, P = 0.001). In multivariable logistic regression analysis with the elevated coefficient of variation at 1 year as the objective variable and age, sex, no daily bowel movement, taking medications, including antihypertensive drugs, laxatives, and intestinal preparations, and coefficient of variation at baseline as independent variables, no daily bowel movement was independently associated with the elevated coefficient of variation at 1 year (odds ratio: 3.81, 95% confidence interval: 1.64-8.87, P = 0.0019). In conclusion, no daily bowel movement was independently associated with elevated day-to-day blood pressure variability at 1 year. Relationship between defecation status and blood pressure level or blood pressure variability.

Association between anthropometric indices and 5-year hypertension incidence in the general Japanese population.

No existing reports demonstrate the association between anthropometric indices (body mass index, waist circumference, body roundness index, a body shape index) and hypertension according to sex and age in the general Japanese population. This retrospective analysis involved individuals aged 30-69 years who underwent annual medical checkups at Kagoshima Koseiren Hospital in 2005-2019, and who did not meet hypertension criteria at baseline. The outcome was hypertension incidence after 5 years, and its association with baseline anthropometric indices was evaluated using multivariable logistic regression analysis by sex and age. In 41,902 participants (age 52.3 ± 10.2 years, 47.7% men), 7622 individuals (18.2%) developed hypertension after 5 years. Body mass index, waist circumference, and body roundness index were significantly associated with the development of hypertension in both men and women across all age categories from 30 s to 60 s. In the population with a body mass index <25 kg/m2, waist circumference and body roundness index were significantly associated with hypertension after 5 years. A body shape index was significantly associated with the development of hypertension in men in their 40 s and 50 s but not in women of any age group. The area under the curve values were lower for a body shape index than for body mass index, waist circumference, and body roundness index in both men and women of all age groups. A body shape index was not a stronger indicator for 5-year hypertension incidence than body mass index, waist circumference, or body roundness index in both men and women across age groups from their 30s-60 s. The results of this study will help to more efficiently identify populations at high risk of developing hypertension and provide preventive interventions. A total of 41,902 participants from health checkup programs were stratified by gender and age to investigate the association between baseline anthropometric indices and hypertension incidence over a 5-year period. BMI, WC, and BRI were almost equally effective and showed a better association with risk of developing hypertension in women and young adults compared to men and old adults. Conversely, ABSI showed no greater association than BMI or WC in any age group in both men and women. ABSI, a body shape index; AUC, area under the curve from receiver operating characteristic curve analysis; BMI, body mass index; BRI, body roundness index; WC, waist circumference.

Triglyceride-glucose index predicts future chronic kidney disease development in all populations, including normotensive and isolated diastolic hypertension.

Hypertension and insulin resistance are established risk factors for chronic kidney disease. However, the association between chronic kidney disease and insulin resistance in detailed hypertension pattern groups such as isolated diastolic hypertension remains unclear. Triglyceride-glucose index has been noted as an indicator of insulin resistance. This study investigated the association between the triglyceride-glucose index and chronic kidney disease in four blood pressure groups: isolated diastolic hypertension, isolated systolic hypertension, systolic diastolic hypertension, and normotension. Using a database of 41,811 middle-aged men who had two or more annual health checkups from 2007 to 2019, those with chronic kidney disease at the first visit, antihypertensive/diabetes/dyslipidemia medication users, and incomplete data were excluded. Four groups were categorized using the 140/90 mmHg threshold. A COX proportional hazards model was used to assess the triglyceride-glucose index with incident chronic kidney disease. Participants were divided: isolated diastolic hypertension: 2207 (6.72%), isolated systolic hypertension: 2316 (7.06%), systolic-diastolic hypertension: 3299 (10.05%), normal: 24,996 (76.17%). The follow-up period was 6.78 years. Adjusted hazard ratios (HRs) and 95% CIs per unit increase in triglyceride-glucose index: isolated diastolic hypertension (HR = 1.31, 95% CI (1.06-1.62)), isolated systolic hypertension (HR = 1.36, 95% CI (1.12-1.64)), systolic-diastolic hypertension (HR = 1.40, 95% CI (1.19-1.64)), normal (HR = 1.18, 95% CI (1.09-1.28)). Triglyceride-glucose index is relevant for predicting chronic kidney disease development in all subtypes of hypertension. The results may lead to early prediction and prevention of the development of chronic kidney disease.

Sex-specific associations between serum uric acid levels and risk of hypertension for different diagnostic reference values of high blood pressure.

The association between uric acid (UA) and hyperuricemia with 5-year hypertension incidence using different blood pressure (BP) diagnostic references in men and women without cardiometabolic diseases is unknown. We used the checkup data from Kagoshima Kouseiren Hospital. All participants with hypertension or on BP medication, diabetes, dyslipidemia, obesity, estimated glomerular filtration rate<60 ml/min/1.73m2, metabolic syndrome, history of gout, and UA-lowering medication were excluded. UA was categorized into sex-specific quartiles and hyperuricemia was defined as UA > 7 mg/dl in men and UA > 6 mg/dl in women. We performed multivariate logistic regression to assess the effects of UA on hypertension development. The 5-year hypertension incidence was defined as subsets of BP ≥ 140/90 mmHg in cohort 1 and BP ≥ 130/80 mmHg in cohort 2. The study enrolled 21,443 participants (39.8%, men) in cohort 1 and 15,245 participants (36.5%, men) in cohort 2. The incidence of hypertension in cohorts 1 and 2 over 5 years was 16.3% and 29.7% in men and 10.9% and 21.4% in women, respectively. When comparing the fourth to the first UA quartile, there was an association with hypertension in men in cohort 1, with odds ratio (OR): 1.36 (95% confidence interval [CI], 1.13-1.63, p < 0.01) and cohort 2, OR: 1.31 (95%CI, 1.09-1.57, p < 0.01), respectively, but not in women. Additionally, an association between hyperuricemia and hypertension was observed in men only in cohort 1, with OR: 1.23 (95%CI, 1.07-1.42, p = 0.02), and in women in cohort 2, OR: 1.57 (95%CI, 1.14-2.16, p < 0.01). The effect of UA on the development of hypertension is influenced by sex and incidence differs with the BP reference used. Uric acid effect on the development of hypertension is affected by sex and incidence differs with the BP reference used.

Colour tone of retinal arterioles imaged with a colour scanning laser ophthalmoscope can be an indicator of systemic arterial stiffness.

OBJECTIVE: Colour scanning laser ophthalmoscope (cSLO) offers several advantages, including improved image quality and better visualisation of the retinal structures compared with colour fundus photograph (CFP). This study aimed to identify whether cSLO could be used to predict systemic arterial stiffness. METHODS AND ANALYSIS: We retrospectively analysed the data of 54 patients with 103 eyes. In addition to blood pressure and blood data, all patients had cardio-ankle vascular index (CAVI) measurements, as well as images of the fundus acquired using cSLO and CFP. We determined the retinal artery sclerosis (RAS) index from the colour of the retinal artery in cSLO images, the ratio of arterial to venous diameter (A/V ratio), and Scheie's classification in CFP images. The correlation between each parameter and CAVI was examined using Spearman's rank correlation coefficient, and the correlation between Scheie's classification and CAVI was examined using Steel-Dowass tests. RESULTS: CAVI showed a significant positive correlation with the RAS index (r=0.679, p<0.001) but not with the A/V ratio or Scheie's classification. Multiple regression analysis showed that the RAS index was significantly and independently correlated with CAVI. CONCLUSION: cSLO is a non-invasive imaging modality that has the potential to accurately and instantaneously detect early systemic arterial stiffness.

J-shaped Association between Serum Uric Acid Levels and the Prevalence of a Reduced Kidney Function: A Cross-Sectional Study Using Japanese Health Examination Data.

Objective While an association between a reduced kidney function and hyperuricemia has been reported, its association with hypouricemia is not well understood. The present study therefore investigated this association. Methods Using a large Japanese health examination dataset, we performed a multivariable logistic regression analysis to assess the association between serum uric acid (SUA) levels and a reduced kidney function. The covariates included the age, body mass index, alcohol intake, and the presence of hypertension, dyslipidemia, or diabetes. Patients This study included 227,672 patients (104,854 men; 46.1%), and the analyses were performed separately for men and women. The patients were classified into 5 groups: hypouricemia (SUA ≤2.0 mg/dL) (1st) and four other (2nd-5th) groups with SUA levels of ≤2.0, 2.1-5.1, 5.2-5.9, 6.0-6.8, ≥6.9 mg/dL in men and ≤2.0, 2.1-3.7, 3.8-4.4, 4.5-5.1, ≥5.2 mg/dL in women, respectively. Results The characteristics of the study population were as follows: men, age 55.9±14.9 years old, SUA 5.9±1.3 mg/dL, estimated glomerular filtration rate (eGFR) 80.0±17.2 mL/min/1.73 m2, and a reduced kidney function (eGFR<60.0 mL/min/1.73 m2) 9.4%; women, age 57.3±15.0 years old, SUA 4.5±1.1 mg/dL, eGFR 81.2±18.0 mL/min/1.73 m2, and a reduced kidney function 9.4%. Compared with the 2nd group, the other 4 groups groups had a significantly higher prevalence of a reduced kidney function [odds ratio (OR), 2.58; 95% confidence interval (CI), 1.64-4.06 in men; OR, 1.66; 95% CI, 1.16-2.39 in women]. Conclusion The prevalence of a reduced kidney function was high in both men and women in the hypouricemia and high-SUA groups. SUA levels and the prevalence of a reduced kidney function showed a J-shaped association.

Changes in Satisfaction with Meaningful Activities and Onset of Depressive Symptoms among Community-Dwelling Japanese Older Adults: A Population-Based Study Before and During the COVID-19 Pandemic.

OBJECTIVES: This study aimed to clarify the association between changes in satisfaction with meaningful activities and the occurrence of depressive symptoms before and during the coronavirus disease 2019 (COVID-19) pandemic. DESIGN: A population-based prospective cohort study (Tarumizu Study). SETTING AND PARTICIPANTS: A total of 231 community-dwelling older adults aged ≥65 years without depressive symptoms at baseline. METHODS: The participants completed baseline (June to December 2018, before the COVID-19 pandemic) and follow-up (September to December 2021, during the COVID-19 pandemic) assessments. Depressive symptoms were assessed using the 15-item Geriatric Depression Scale (GDS-15) and defined by a GDS-15 score of ≥5. Participants selected meaningful activities from the 95 activities included in the Aid for Decision-Making in Occupation Choice, and their satisfaction levels were evaluated. Satisfaction with the most meaningful activities was assessed as to whether it was maintained/improved or decreased at follow-up. RESULTS: In the follow-up survey, 31 (14.3%) participants reported the occurrence of depressive symptoms. Compared with before the COVID-19 pandemic, the rates of meaningful activities during the COVID-19 pandemic decreased for interpersonal interaction and social life and increased for leisure, sports, self-care, and domestic life. Logistic regression analysis revealed that changes in satisfaction with meaningful activity were associated with the occurrence of depressive symptoms after adjusting for demographic variables, baseline GDS scores, cognitive and physical status, and instrumental activities of daily living (odds ratio, 2.78; 95% confidence interval, 1.17-6.59, P = .020). CONCLUSIONS AND IMPLICATIONS: To avoid decreasing satisfaction with meaningful activities, supporting older adults may be protective against the occurrence of depressive symptoms. Our findings highlight the need for health care professionals to not only encourage older adults to participate in activities for their mental health but also consider whether the activities are meaningful or satisfying for them.

Development of predictive equation and score for 5-year metabolic syndrome incidence in Japanese adults.

BACKGROUND: Predicting metabolic syndrome (MetS) is important for identifying high-risk cardiovascular disease individuals and providing preventive interventions. We aimed to develop and validate an equation and a simple MetS score according to the Japanese MetS criteria. METHODS: In total, 54,198 participants (age, 54.5±10.1 years; men, 46.0%), with baseline and 5-year follow-up data were randomly assigned to 'Derivation' and 'Validation' cohorts (ratio: 2:1). Multivariate logistic regression analysis was performed in derivation cohort and scores were assigned to factors corresponding to ß-coefficients. We evaluated predictive ability of the scores using area under the curve (AUC), then applied them to validation cohort to assess reproducibility. RESULTS: The primary model ranged 0-27 points had an AUC of 0.81 (sensitivity: 0.81, specificity: 0.81, cut-off score: 14), and consisted of age, sex, blood pressure (BP), body mass index (BMI), serum lipids, glucose measurements, tobacco smoking, and alcohol consumption. The simplified model (excluding blood tests) ranged 0-17 points with an AUC of 0.78 (sensitivity: 0.83, specificity: 0.77, cut-off score: 15) and included: age, sex, systolic BP, diastolic BP, BMI, tobacco smoking, and alcohol consumption. We classified individuals with a score <15 and ≥15 points as low- and high-risk MetS, respectively. Furthermore, the equation model generated an AUC of 0.85 (sensitivity: 0.86, specificity: 0.55). Analysis of the validation and derivation cohorts yielded similar results. CONCLUSION: We developed a primary score, an equation model, and a simple score. The simple score is convenient, well-validated with acceptable discrimination, and could be used for early detection of MetS in high-risk individuals.

Development of a risk prediction score and equation for chronic kidney disease: a retrospective cohort study.

Chronic kidney disease (CKD) is a risk factor for end-stage renal disease and contributes to increased risk of cardiovascular disease morbidity and mortality. We aimed to develop a risk prediction score and equation for future CKD using health checkup data. This study included 58,423 Japanese participants aged 30-69 years, who were randomly assigned to derivation and validation cohorts at a ratio of 2:1. The predictors were anthropometric indices, life style, and blood sampling data. In derivation cohort, we performed multivariable logistic regression analysis and obtained the standardized beta coefficient of each factor that was significantly associated with new-onset CKD and assigned scores to each factor. We created a score and an equation to predict CKD after 5 years and applied them to validation cohort to assess their reproducibility. The risk score ranged 0-16, consisting of age, sex, hypertension, dyslipidemia, diabetes, hyperuricemia, and estimated glomerular filtration rate (eGFR), with area under the curve (AUC) of 0.78 for the derivation cohort and 0.79 for the validation cohort. The CKD incidence gradually and constantly increased as the score increased from ≤ 6 to ≥ 14. The equation consisted of the seven indices described above, with AUC of 0.88 for the derivation cohort and 0.89 for the validation cohort. We developed a risk score and equation to predict CKD incidence after 5 years in Japanese population under 70 years of age. These models had reasonably high predictivity, and their reproducibility was confirmed through internal validation.

Clinical significance of atherosclerotic risk factors differs in early and advanced stages of plaque formation: A longitudinal study in the general population.

BACKGROUND: Carotid plaque is a well-known prognostic factor for cardiovascular diseases. It is unclear which risk factors are associated with the transformation of carotid plaque over time. In this longitudinal study, we examined the risk factors related to carotid plaque progression. METHODS: We enrolled 738 men without medication (mean age: 55 ± 10 years) who underwent the first and second health examinations. We measured carotid plaque thickness (PT) at three points of the right and left carotid artery. Plaque score (PS) was calculated by summing all the PTs. We divided the PS into three groups: None-group (PS <1.1), Early-group (1.1 ≤ PS <5.1), and Advanced-group (PS ≥5.1). We analyzed the relationship between PS progression and parameters such as age, body mass index, systolic blood pressure (SBP), fasting blood sugar, low-density lipoprotein cholesterol (LDL-C), and smoking and exercise habits. RESULTS: In multivariable logistic regression analysis, age and SBP were independent factors for PS progression from none to early stages (age, OR 1.07, p = 0.002; SBP, 10 mmHg, OR 1.27, p = 0.041). Age, follow-up period and LDL-C were independently associated factors for PS progression from early to advanced stages (age, OR 1.08,p < 0.001; follow-up period OR1.19, p = 0.041; LDL-C, 10 mg/dL, OR 1.10, p = 0.049). CONCLUSIONS: SBP was independently associated with the progress of early atherosclerosis, while LDL-C was independently associated with the progression of advanced atherosclerosis in the general population. Further studies are needed to assess whether early control of SBP and LDL-C levels can reduce the occurrence of future cardiovascular events.

Relationship between grave visitation and apathy among community-dwelling older adults.

BACKGROUND: It has been shown that involvement in religious activities has a positive impact on psychological aspects. In this study, the relationship between grave visitation, a standard religious activity in Japan, and depression and apathy symptoms was investigated among older adults in Japan. METHODS: A total of 638 older adults who participated in a community-based health check survey (Tarumizu Study 2019) were interviewed regarding the presence or absence of grave visitation, frequency, travel time, means of transportation, and flower offerings. Apathy and depressive symptoms were measured using the 15-item Geriatric Depression Scale (GDS-15). The participants were categorised into three grave visitation groups, namely, frequent (more than once per week), occasional (less than once per week), and non-visiting. Outcomes were compared between the frequency groups, and Poisson regression analysis was used to investigate the relationship between grave visitation frequency and apathy and depression. RESULTS: Of the participants, 91.8% reported regular grave visitation. The non-visiting group had a significantly higher prevalence of apathy symptoms (44.2%) than the visiting groups. Furthermore, using the frequent group as the reference, Poisson regression analysis adjusted for potential covariates demonstrated that no grave visitation was significantly related to apathy (prevalence ratio, 1.43; 95% confidence interval, 1.00-2.05, P = 0.049). CONCLUSIONS: Not practising grave visitation was significantly related to apathy among older adults. Helping older adults to visit graves may prevent apathy by facilitating motivation and increasing activity.

Cutoff Values of Brachial-Ankle Pulse Wave Velocity for Atherosclerotic Risks by Age and Sex in the Japanese General Population.

AIM: In this study, we aim to analyze the correlation between brachial-ankle pulse wave velocity (baPWV) and Suita score or Framingham risk score and obtain the cutoff value of baPWV by sex and age for cardiovascular risk, as assessed by these scores in the large Japanese annual health checkup data. METHODS: In total, 25,602 participants (14,539 men and 11,063 women), who had their annual health checkups, were included in this study. Cutoff values of baPWV for the moderate- and high-risk groups stratified by sex and age were obtained using a receiver operating characteristic (ROC) curve analysis. RESULTS: As per our findings, the Suita score demonstrated better correlations with baPWV than the Framingham risk score in both sexes (men, Suita score R2=0.41 and Framingham risk score R2=0.37; women, Suita score R2=0.54 and Framingham risk score R2=0.33). The ROC curve analysis demonstrated the cutoff values of baPWV for moderate- and high-risk groups estimated using the Suita score, and they are as follows: in men, the baPWV cutoff values were 1,350 cm/s in the 40s, 1,430 cm/s in the 50s, 1,520 cm/s in the 60s, and 1,880 cm/s in the 70s. In women, the baPWV cutoff values were 1,350 cm/s in the 40s, 1,430 cm/s in the 50s, 1,570 cm/s in the 60s, and 1,800 cm/s in the 70s. CONCLUSIONS: We demonstrated that baPWV significantly correlated with the Suita score or Framingham risk score in both men and women, with the former presenting a stronger correlation than the latter. We propose the cutoff values of baPWV for moderate- and high-risk groups estimated using the Suita score.

Social Frailty and Meaningful Activities among Community-Dwelling Older Adults with Heart Disease.

Patients with heart disease are more likely to experience social frailty due to physical inactivity, which may affect meaningful activities such as hobbies. This study aimed to investigate (1) the association between heart disease and social frailty in community-dwelling older adults and (2) the characteristics of meaningful activities in community-dwelling older adults with heart disease. Data from 630 older adults who participated in a community-based health survey were obtained, including clinical history, meaningful activities, social frailty and psychosomatic functions. Participants were divided into two groups: those with heart disease (n = 79) and those without (n = 551), and comparisons were made. Social frailty was observed in 23.7% of participants with heart disease, and logistic regression revealed significant associations with heart disease and social frailty after adjusting for potential covariates (OR, 1.97; 95% CI, 1.06 3.67; p = 0.032). Participants with heart disease did not differ significantly in terms of satisfaction or performance; their frequency of engagement in meaningful activities was significantly lower than without heart disease (p = 0.041). These results suggest that heart disease and social frailty are associated in community-dwelling older adults, and that this demographic is inclined to engage in meaningful activities less frequently.

Insufficient blood pressure control is independently associated with increased arterial stiffness.

Hypertension is a risk factor for atherosclerosis. Achieving the therapeutic target value of blood pressure (BP) prevents the onset of cardiovascular events; however, it is not clear how antihypertensive drug use and BP control status relate to arterial stiffness. The purpose of this study is to investigate the relationship between BP control status with or without antihypertensive drugs and arterial stiffness. Nine hundred eighty individuals (mean age: 68 ± 11 years) who participated in a community-based cohort study were enrolled. Arterial stiffness was evaluated using the cardio-ankle vascular index (CAVI). Higher BP was defined as a systolic BP ≥ 140 mmHg or diastolic BP ≥ 90 mmHg. Participants were divided into four groups: normal, non higher BP without antihypertensive drugs (n = 421); untreated, higher BP without antihypertensive drugs (n = 174); good control, non higher BP with antihypertensive drugs (n = 209); and poor control, higher BP with antihypertensive drugs (n = 176). In multivariable logistic analysis adjusted for age, sex, dyslipidemia and diabetes mellitus medication use, obesity, smoking, alcohol drinking, and heart rate at the CAVI measurement for a high CAVI-using a borderline cutoff value of 8.0-the other three groups were significantly associated with a high CAVI when compared with the normal group. By contrast, multivariable logistic analysis of a high CAVI using an abnormal cutoff value of 9.0 demonstrated that the poor control and untreated groups were significantly associated with a high CAVI, whereas the good control group was not. In conclusion, even with antihypertensive drugs, poor BP control is independently associated with a high CAVI.
