Abstract
BACKGROUND Alcohol consumption is a modifiable lifestyle, but its role in heart failure (HF) development is controversial. Herein, we investigated the prospective association between alcohol consumption and HF risk. METHODS A total of 2,712 participants (1,149 men and 1,563 women) from the Suita Study were followed up every two years. Cox regression was applied to calculate the hazard ratios (HRs) and 95% confidence intervals (95% CIs) of HF risk for heavy drinking (≥46 g/day in men or ≥23 g/day in women) and never drinking compared to light drinking (<23 g/day in men or <11.5 g/day in women). Then, we combined the results of the Suita Study with those from other eligible prospective cohort studies in a meta-analysis using the random-effects model. RESULTS In the Suita Study, within a median follow-up period of 8 years, 319 HF cases (162 in men and 157 in women) were detected. In men, but not women, never and heavy drinking carried a higher risk of HF than light drinking: HRs (95% CIs) = 1.65 (1.00, 2.73) and 2.14 (1.26, 3.66), respectively. Alike, the meta-analysis showed a higher risk of HF among heavy drinkers: HR (95% CI) = 1.37 (1.15, 1.62) and abstainers: HR (95% CI) = 1.18 (1.02, 1.37). CONCLUSION We indicated a J-shaped association between alcohol consumption and HF risk among Japanese men. The results of the meta-analysis came in line with the Suita Study. Heavy-drinking men should be targeted for lifestyle modification interventions.

Abstract
BACKGROUND The incidence and prevalence of atrial fibrillation (AF) are increasing. The white blood cell (WBC) count is an indicator of systemic inflammation and is related to increased cardiovascular disease risk. Using data from the Suita Study, we investigated the association between WBC count and AF risk in the general Japanese population.Methods and Results: This prospective cohort study included 6,884 people, aged 30-84 years, with no baseline AF. Cox regression was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for AF incidence by WBC count quintile. Within a median follow-up period of 14.6 years, 312 AF cases were diagnosed. Compared with the lowest WBC count quintile, the highest quintile was associated with an increased AF risk (HR 1.57; 95% CI 1.07-2.29). The association was more pronounced among women than men (HR 2.16 [95% CI 1.10-4.26] and 1.55 [95% CI 0.99-2.44], respectively; P interaction=0.07), and among current than non-smokers (HR 4.66 [95% CI 1.89-11.50] and 1.61 [95% CI 1.01-2.57], respectively; P interaction=0.20). For each 1.0×109-cells/L increment in WBC count, AF risk increased by 9% in men (9% in non-smokers, 10% in current smokers) and 20% in women (13% in non-smokers, 32% in current smokers). CONCLUSIONS A higher WBC count was positively associated with an elevated AF risk in the general Japanese population, especially in women who smoked.

Abstract
Background Engaging in leisure activities was suggested to protect older adults from dementia. However, the association between playing a musical instrument and the risk of dementia is not well-established. This study aimed to investigate this association in older adults using a systematic review and meta-analysis of prospective cohort studies. Methods Pooled hazard ratio (HR) and 95% confidence interval (CI) of having dementia for older adults playing a musical instrument were calculated using the random-effects model. We performed the I2 statistic to detect heterogeneity across studies and the test for funnel plot asymmetry to assess publication bias. The risk of bias assessment was conducted using the modified Newcastle–Ottawa Scale. Results A total of three prospective cohort studies were found eligible: two from the U.S. and one from Japan. Playing a musical instrument, in the meta-analysis, was significantly associated with a decreased risk of dementia (HR = 0.64; 95% CI: 0.41, 0.98) among older adults. No signs of significant heterogeneity across studies (I2 = 23.3% and p-heterogeneity = 0.27) or publication bias (z= -1.3 and p-publication bias = 0.18) were identified. Conclusion Playing a musical instrument was associated with a decreased risk of dementia among older adults. Older adults should be encouraged to engage in leisure activities, especially playing musical instruments.

Abstract
Abstract
Background
Recently, the concept of healthy vascular aging (HVA) and early vascular aging (EVA) phenotypes was proposed.
Purpose
We examined following issues; constancy of the vascular phenotypes over time; validity of assuming that constancy of the vascular phenotypes reflects the progression rate of structural arterial stiffening; and associations of vascular phenotype constancy with cardiovascular risk factors/their treatment, and the heart rate (HR).
Methods
Data on the brachial-ankle pulse wave velocity (baPWV) measured annually over a 16-year period in 4682 middle-aged Japanese employees were analyzed.
Results
Of all subjects, 30% showed constancy of the vascular phenotype during the study period. The estimated marginal mean of baPWV values and the slope of the annual increase of the baPWV were higher in the constant EVA group (EVA-EVA) than in the constant HVA group (HVA-HVA) (Figure 1). Elevated serum HbA1c levels, medication for hypertension, and high HR were significantly associated with constancy of the EVA phenotype, whereas a low HR was significantly associated with constancy of the HVA phenotype.
Conclusions
In middle-aged Japanese employees with the HVA/EVA phenotype at the study baseline, while the phenotype changed over time in most subjects, HVA/EVA phenotype constancy in the remaining subjects reliably reflected a low/high rate of progression of structural arterial stiffening. Hypertension and abnormal glucose metabolism were associated with constancy of the EVA phenotype, but treatment for these conditions failed to improve the phenotype. Low/high HR was a robust marker of the presence/constancy of the HVA/EVA phenotype.

Abstract
Abstract
Background
Hypertension and diabetes mellitus frequently coexist; however, it has not yet been clarified if the bidirectional longitudinal relationships between arterial stiffness and hypertension are independent of those between arterial stiffness and diabetes mellitus.
Methods
In this 16-year prospective observational study, 3960 middle-aged employees of a Japanese company without hypertension/diabetes mellitus at the study baseline underwent annual repeated measurements of the blood pressure, serum glycosylated hemoglobin A1c levels (HbA1c), and brachial-ankle pulse wave velocity (baPWV).
Results
By the end of the study period, 664, 779, 154, and 406 subjects developed hypertension, prehypertension, diabetes mellitus, and prediabetes, respectively. Increased baPWV at the baseline was associated with a significant odds ratio (per 1 standard deviation increase) for new onset of prehypertension/hypertension with (2.45/3.28, P<0.01) or without (2.49/2.76, P<0.01) coexisting prediabetes/diabetes mellitus, but not for new onset of prediabetes/diabetes mellitus without coexisting hypertension. Analyses using the latent growth curve model confirmed the bidirectional relationships between baPWV and hypertension, but no such relationship was observed between baPWV and abnormal glucose metabolism. Moreover, after the adjustments, higher mean blood pressure at baseline accelerated the increases in the baPWV over follow-up (unstandardized coefficient [B] = 0.39, standard error [SE] = 0.05x10–1, P<0.01). Similarly, higher baPWV at baseline accelerated the increases in mean blood pressure over follow-up (B = 0.02x10–1, SE = 0.01x10–1, P<0.01) (Figure 1). On the other hands, higher HbA1c levels at baseline accelerated the increases in the baPWV over follow-up (B = 0.43, SE = 0.05x10–1, P<0.01), but higher baPWV at baseline did not accelerate the increases in HbA1c levels over follow-up (B <0.01, SE <0.01, P=0.52) (Figure 2).
Conclusions
In middle-aged employees of a Japanese company, in contrast to the bidirectional relationships that exist between arterial stiffness and hypertension, increased arterial stiffness preceding the development of diabetes mellitus may represent that associated with the development of hypertension, as it is observed only in cases of diabetes mellitus coexisting with hypertension. Therefore, arterial stiffness may be associated to a greater degree with the development of hypertension than with the development of diabetes mellitus.

Abstract
Abstract
Backgrounds
While arterial stiffness and abnormal pressure wave reflection are independent cardiovascular risk, the difference of their association with alcohol intake have not been fully clarified.
Aim
This prospective observational study, which utilized repeated annual measurements performed over a 9-year period, applied mixed model analyses to examine age-related differences in longitudinal associations between alcohol intake and arterial stiffness, pressure wave reflection, and inflammation.
Methods
In 4016 middle-aged (43±9 years) healthy Japanese male employees, alcohol intake, brachial-ankle pulse wave velocity (baPWV), radial augmentation index (rAI), and serum C-reactive protein (CRP) levels were measured annually during a 9-year study period. Based on the questionnaire, alcohol intake was classified as non-drinker, mild-moderate drinker (ethanol 1–20 g/day) and heavy drinker (>20 g/day).
Results
The estimated marginal mean baPWV (non-drinkers = 1306 cm/s, mild-moderate drinkers = 1311 cm/s, and heavy drinkers = 1337 cm/s, P<0.01) and that of rAI showed significant stepped increases in an alcohol dose-dependent manner in the entire cohort, but an increase in rAI was not observed in subjects aged ≥50 years. The estimated slope of the annual increase in baPWV, but not rAI, was higher for heavy drinkers than for non-drinkers (slope difference, 2.73; P<0.01), especially for subjects aged <50 years. The estimated marginal mean of the serum CRP levels was lower for drinkers than for non-drinkers.
Conclusion
In middle-aged male Japanese employees, alcohol intake may attenuate inflammatory activity. While alcohol intake may exacerbate the progression of arterial stiffening in a dose-dependent manner without mediating inflammation, especially in subjects under 50 years of age, it may promote pressure wave reflection abnormalities with aging at earlier ages without further exacerbation at older ages.

Abstract
Glucocorticoids are widely used for a variety of diseases, but the prevention of glucocorticoid-induced osteoporosis is sometimes neglected. Therefore, the effectiveness of a computerized clinical decision support system (CDSS) to improve the performance rate of preventive care for glucocorticoid-induced osteoporosis was evaluated. We conducted a prospective cohort study of outpatients who used glucocorticoids for three months or longer and who met the indication for preventive care based on a guideline. The CDSS recommended bisphosphonate (BP) prescription and bone mineral density (BMD) testing based on the risk of osteoporosis. The observation period was one year (phase 1: October 2017-September 2018) before implementation and the following one year (phase 2: October 2018-September 2019) after implementation of the CDSS. Potential alerts were collected without displaying them during phase 1, and the alerts were displayed during phase 2. We measured BP prescriptions and BMD testing for long-term prescription of glucocorticoids. A total of 938 patients (phase 1, 457 patients; phase 2, 481 patients) were included, and the baseline characteristics were similar between the phases. The median age was 71 years, and men accounted for 51%. The primary disease for prescription of glucocorticoids was rheumatic disease (28%), followed by hematologic diseases (18%). The prevalence of patients who needed an alert for BP prescription (67% vs. 63%, P = 0.24) and the acceptance rate of BP prescription (16% vs. 19%, P = 0.33) were similar between the phases. The number of patients who had orders for BMD testing was significantly increased (4% vs. 24%, P < 0.001) after CDSS implementation. The number of patients who needed an alert for BMD testing was significantly decreased from 93% in phase 1 to 87% in phase 2 (P = 0.004). In conclusion, the CDSS significantly increased BMD testing in patients with a higher risk of glucocorticoid-induced osteoporosis, but did not increase BP prescription.

Abstract
Background: Although reductions in hospitalizations for myocardial infarction and heart failure have been reported during the period of COVID-19 pandemic restrictions, it is unclear how the overall number of hospitalizations for cardiovascular disease (CVD) treatment changed in the early stages of the pandemic. Methods and Results: We analyzed the records of 574 certified hospitals affiliated with the Japanese Circulation Society and retrieved data from April 2015 to March 2020. Records were obtained from the nationwide Japanese Registry of All Cardiac and Vascular Diseases–Diagnosis Procedure Combination database. A quasi-Poisson regression model was used to estimate the number of hospitalizations for CVD treatment. Between January and March 2020, when the number of COVID-19 cases was relatively low in Japan, the actual/estimated number of hospitalizations for acute CVD was 18,233/21,634 (84.3%), whereas the actual/estimated number of scheduled hospitalizations was 16,921/19,066 (88.7%). The number of hospitalizations for acute heart failure and scheduled hospitalizations for valvular disease and aortic aneurysm were 81.1%, 84.6%, and 83.8% of the estimated values, respectively. A subanalysis that considered only facilities without hospitalization restrictions did not alter the results for these diseases. Conclusions: The spread of COVID-19 was associated with a decreased number of hospitalizations for CVD in Japan, even in the early stages of the pandemic.

Abstract
There is little evidence of how blood pressure level over 10 years affects the decline of estimated glomerular filtration rate (eGFR) in diabetic patients. The Japanese primary prevention of atherosclerosis with aspirin for diabetes (JPAD) trial was a multicenter, randomized, clinical trial done from 2002 to 2008. After completion of the JPAD trial, we followed up the patients until 2019 as a cohort study. We defined late-stage kidney disease (LSKD) as eGFR < 30 ml/min/1.73 m2 or hemodialysis. Based on the mean value of systolic blood pressure (SBP) obtained average 7 times during the follow-up, we divided the patients into three groups: a high SBP group (n = 607, SBP ≥ 140 mm Hg); a moderate SBP group (n = 989, 140 > SBP ≥ 130 mm Hg); or a low SBP group (n = 913, SBP < 130 mm Hg). There was no significant deference in the mean eGFR among the high SBP, moderate SBP and low SBP groups on registration. The incidence rate of LSKD was significantly higher in the high SBP (HR 2.02, 95% CI 1.36-3.01) and moderate SBP (HR 1.54, 95% CI 1.07-2.20) groups than in the low SBP group (Log-Rank P = 0.0018). Cox proportional hazards model analysis revealed that the high SBP (HR, 1.57, P = 0.049) and moderate SBP (HR, 1.52, P = 0.037) were independent factors after adjustment for proteinuria ≥ ± , age ≥ 65 years, men, body mass index ≥ 24 kg/m2, duration of diabetes ≥ 7.0 years, statin usage, eGFR ≥ 60 ml/min/1.73 m2, hemoglobin A1c ≥ 7.2%, and smoking status. Our 11.2 year follow-up study demonstrated that mean SBP was independently associated with the progression to LSKD in diabetic patients. These findings may become new evidence that SBP less than 130 mm Hg is recommended for diabetic patients to prevent progression to LSKD.

Abstract
INTRODUCTION The incidence of atrial fibrillation (AF), a significant risk factor for cardiovascular disease (CVD), is increasing worldwide. Type 2 diabetes mellitus (T2D) and advanced age are recognized as major risk factors for AF, but herein, we evaluated the incidence of AF in elderly patients with T2D and compared the prognosis between these patients with/without AF. RESEARCH DESIGN AND METHODS The Japanese Primary Prevention of Atherosclerosis with Aspirin for Diabetes (JPAD2) study is a follow-up cohort study of the JPAD trial, a randomized controlled clinical trial initiated in 2002 in 2535 Japanese patients with T2D, to examine whether low-dose aspirin prevents CVD. After completion of that trial, we followed up the patients until 2019 and evaluated the incidence of AF. We also compared the incidence of cerebral cardiovascular events in elderly patients with T2D with/without AF. RESULTS During the median follow-up period of 10.9 years, 132 patients developed AF (incidence rate: 5.14/1000 person-years). The adjusted HRs for cerebral cardiovascular events, stroke, coronary artery disease, heart failure, and all-cause death in elderly patients with T2D with versus without AF were 1.65 (95% CI 1.03 to 2.66), 1.54 (95% CI 0.81 to 2.93), 1.96 (95% CI 1.03 to 3.73), 5.17 (95% CI 2.46 to 10.89), and 1.82 (95% CI 1.24 to 2.67), respectively. CONCLUSIONS Annually, 1 in 200 elderly Japanese patients with T2D are estimated to develop AF. Because elderly patients with T2D with AF are at an elevated risk for CVD, careful follow-up of this patient subgroup is necessary. TRIAL REGISTRATION NUMBER NCT00110448.

Abstract
OBJECTIVE Obstructive sleep apnea (OSA) is recognized as an independent risk factor for cardiovascular disease. On the other hand, inter-arm systolic blood pressure difference (IAD), inter-ankle systolic blood pressure difference (IAND), and ankle-brachial index (ABI) are all known predictors of cardiovascular events. The aim of the present study was to investigate the association between OSA and four-limb blood pressure differences. METHODS We conducted this cross-sectional study in a large sleep cohort from Tokyo Sleep Heart Study. In 2643 consecutive patients who visited our sleep clinic for polysomnography between 2005 and 2017, all the patients underwent blood pressure measurement simultaneously in all the four limbs by oscillometric methods. RESULTS The prevalence rate of IAD ≥10 mmHg was significantly higher in the moderate OSA (15 ≤ apnea-hypopnea index [AHI] < 30) group (4.2%) and severe OSA (AHI ≥ 30) group (4.6%) than that in the no/mild (AHI < 15) OSA group (1.4%). Multivariate logistic regression analysis also identified moderate to severe OSA as being significantly associated with IAD ≥10 mmHg, even after adjustments for confounding variables (moderate OSA: odds ratio [OR], 4.869; 95% confidence interval [CI], 1.080-21.956; P = 0.039; severe OSA: OR, 5.301; 95% CI, 1.226-22.924; P = 0.026). However, there were no significant associations of the OSA severity with IAND ≥15 mmHg or ABI <0.9. CONCLUSIONS Moderate to severe OSA was independently associated with the IAD, not but with the IAND or ABI.

Abstract
AIMS This prospective observational study aimed to examine the individual longitudinal associations of the increases in the arterial stiffness and pressure wave reflection with the decline in the cardiac systolic performance during the study period in healthy middle-aged Japanese men. METHODS In 4016 middle-aged Japanese healthy men (43±9 years), the brachial-ankle pulse wave velocity (baPWV), radial augmentation index (rAI), and pre-ejection period/ejection time (pre-ejection period (PEP)/ET) were measured annually during a 9-year study period. RESULTS The baPWV, rAI, and PEP/ET showed steady annual increases during the study period. According to the results of multivariate linear regression analyses, both the baPWV and rAI measured at the baseline showed significant independent associations with the PEP/ET measured at the baseline (baPWV: beta=0.17, p<0.01 and rAI: beta=0.11, p<0.01), whereas neither showed any association with the PEP/ET measured at the end of the study period. The results of the mixed-model linear regression analysis of the repeated-measures data collected over the 9-year study period revealed that the baPWV, but not the rAI, showed a significant longitudinal association with the PEP/ET (estimate=0.69 x 10-4, p<0.01). CONCLUSION In apparently healthy middle-aged Japanese men, the annual increase of the arterial stiffness, rather than the annual increase of the pressure wave reflection, appears to be more closely associated with the annual decline of the cardiac systolic performance as assessed by the systolic time interval.

Abstract
Background: In Japan, district differences in the prevalence of cardiovascular disease (CVD) are well-known. This study examined district differences in Japan in measured values of arterial stiffness, an independent risk factor for CVD. Methods and Results: Local residents participating in health checkups conducted in the Wakayama (n=461) and Nagano (n=186) prefectures in 2018 were recruited to the study. Brachial-ankle pulse wave velocity (baPWV) was evaluated as an index of arterial stiffness. After multivariate adjustment, baPWV was significantly higher in the Wakayama than Nagano district in subjects aged ≥70 years (mean [±SE] 1,912±25 vs. 1,763±30 cm/s; P<0.01), but not in subjects aged <70 years. Multivariate linear regression analysis demonstrated that the Wakayama/Nagano district difference was significantly (P<0.01) associated with baPWV. Conclusions: District differences were observed in the measured values of arterial stiffness in Wakayama and Nagano. The Wakayama and Nagano prefectures are representative areas with a relatively high and relatively low prevalence of CVD, respectively, in Japan. Therefore, based on the results of the present study, we propose to conduct a study to examine whether district differences in arterial stiffness underlie district differences in the prevalence of CVD.

Abstract
Background:
Frailty is associated with higher risk of cardiovascular disease (CVD) and mortality. Recently, oral hypofunction, a disease in which the oral function is complexly reduced not only by ageing but also by a variety of factors, is regarded as a major risk factor for frailty, as it develops malnutrition and sarcopenia. However, no studies have evaluated the association of oral hypofunction and arterial stiffness, a marker for CVD.
Hypothesis:
We hypothesized that subjects with oral hypofunction have increased arterial stiffness compared to those without oral hypofunction.
Methods:
Japanese subjects above 50 years old who underwent annual health checkup were enrolled in this cross-sectional study. Subjects with history of CVD and dementia were excluded. Arterial stiffness was evaluated by brachial-ancle pulse wave velocity (baPWV). Oral hypofunction was evaluated based on the guidance by the Japanese Association for Dental Science. Seven oral factors, oral hygiene, oral moisture, occlusal force, tongue-lip motor function, tongue pressure, masticatory function, and swallowing function were assessed. Oral hypofunction was diagnosed if more than 3 factors showed deterioration. The association of oral hypofunction and baPWV was evaluated by multivariate linear regression analysis adjusted for conventional CVD risk factors. We also performed subgroup analysis stratified by age. (<60, ≧60 years).
Results:
Among 148 subjects (mean age: 59±7 years), 34 subjects (23%) had oral hypofunction. BaPWV in subjects with oral hypofunction was significantly higher than subjects without oral hypofunction (mean baPWV: 1539±312 v.s. 1416±260cm/sec, p=0.02). However, after adjustment for CVD risk factors, oral hypofunction did not significantly associate with baPWV (β=46±49, p=0.35). On the other hand, in subgroup analysis, oral hypofunction was significantly associated with increased baPWV among subjects in subjects younger than 60 years old even after adjustment of CVD risk factors (β=135±67, p=0.046), but this association was not observed in subjects over 60s.
Conclusion:
Oral hypofunction was associated with increased arterial stiffness, especially in subjects younger than 60s. Further research on oral hypofunction and CVD is warranted.

Heart rate modulates the relationship of augmented systolic blood pressure with the blood natriuretic peptide levels. ESC Heart Fail 2021; 8:3957-3963. [PMID: 34323018 PMCID: PMC8497200 DOI: 10.1002/ehf2.13540] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Revised: 06/01/2021] [Accepted: 07/13/2021] [Indexed: 11/12/2022] Open
Abstract
AIMS Augmented central systolic blood pressure (cSBP), which is known to affect the cardiac afterload, is an independent risk factor for cardiovascular disease. While an inverse relationship is known to exist between the heart rate (HR) and the cSBP, it has not yet been clarified if the HR also modulates the association between the cSBP and the cardiac afterload. The present study was conducted to clarify whether the association of the cSBP with the serum levels of the N-terminal fragment B-type natriuretic peptide (NT-proBNP) differs between subjects with high and low HRs, using data obtained from the same subjects on two occasions (2009 and 2012) so as to confirm their consistency. METHODS AND RESULTS The radial augmentation index, systolic pressure at the second peak of the radial pressure waveform (SBP2), and serum NT-proBNP levels were measured and analysed in a worksite cohort of 2000 middle-aged men in 2009 and in 2012. The subjects were divided into three groups by the HR (i.e. ≤69, 70-79, and ≥80 b.p.m.). While the serum NT-proBNP levels were similar among the three groups, the radial augmentation index increased (from 61 ± 12% to 72 ± 13%, P < 0.01 in 2009 and from 61 ± 13% to 73 ± 12%, P < 0.01 in 2012) and the SBP1-2 decreased (from 18 ± 7 to 13 ± 7 mmHg, P < 0.01 in 2009 and from 19 ± 7 to 13 ± 6 mmHg, P < 0.01 in 2012) significantly with decreasing HR. After the adjustment, the SBP2 showed a significant association with the serum NT-proBNP levels in the overall study population [non-standardized coefficient (B) = 0.005, standard error (SE) = 0.001, P < 0.01 in 2009 (n = 2257) and B = 0.004, SE = 0.001, P < 0.01 in 2012 (n = 1986)]. In subgroup analyses, the SBP2 showed a significant association with the serum NT-proBNP levels [B = 0.004, SE = 0.002, P = 0.02 in 2009 (n = 1291) and B = 0.005, SE = 0.001, P < 0.01 in 2012 (n = 1204)] only in the subject group with an HR of ≤69 b.p.m. CONCLUSIONS In middle-aged Japanese men, the relationship between the cSBP and the cardiac afterload appears to differ depending on the HR; the results of our analysis showed that the relationship between the cSBP and the cardiac overload may be more pronounced and strongly significant in patients with low HRs as compared with patients with high HRs.

Abstract
Background:
The relationship between Twitter ambassadors and retweets has not been fully evaluated for “tweet the meeting” activity. Methods and Results:
We collected data on the number of tweets and retweets during the Japanese Circulation Society’s (JCS) annual meetings in 2019, 2020, and 2021. After adjustment, JCS Twitter Ambassadors, selected by the JCS to increase the meeting’s visibility, increased the total number of retweets by 9%. Conclusions:
This is the first report on the numerical relationship between JCS Twitter Ambassadors and the total number of retweets during an annual congress. Original tweets by JCS Twitter Ambassadors increased the number of retweets, but retweets by influencers were more effective at stimulating social media engagement.

Abstract
Background:
This prospective observational study examined whether hyperuricemia may be associated with impaired left ventricular (LV) systolic function and increased cardiac load resulting from increased arterial stiffness. Methods and Results:
In 1,880 middle-aged (mean [±SD] age 45±9 years) healthy men, serum uric acid (UA) levels, pre-ejection period/ejection time (PEP/ET) ratio, serum N-terminal pro B-type natriuretic peptide (NT-proBNP) levels, and brachial-ankle pulse wave velocity (baPWV) were measured at the start and end of the 3-year study period. Linear regression analysis revealed that serum UA levels measured at baseline were significantly associated with the PEP/ET ratio, but not with serum NT-proBNP levels, measured at baseline (β=0.73×10−1, P<0.01) and at the end of the study period (β=0.68×10−1, P<0.01). The change in the PEP/ET ratio during the study period was significantly greater in the High-UA (UA >7 mg/dL in 2009 and 2012) than Low-UA (UA ≤7 mg/dL in 2009 and 2012) group. Mediation analysis demonstrated both direct and indirect (via increases in baPWV) associations between serum UA measured at baseline and the PEP/ET ratio measured at the end of the study period. Conclusions:
In healthy middle-aged Japanese men, hyperuricemia may be associated with an accelerated decline in ventricular systolic function, both directly and indirectly, via increases in arterial stiffness.

Abstract
BACKGROUND The antitumor effect of statins has been highlighted, but clinical study results remain inconclusive. While patients with diabetes are at high risk of cancer, it is uncertain whether statins are effective for cancer chemoprevention in this population. OBJECTIVE This study evaluated the association between statins and cancer incidence/mortality in patients with type 2 diabetes. DESIGN This study was a follow-up observational study of the Japanese Primary Prevention of Atherosclerosis with Aspirin for Diabetes (JPAD) trial, which was a randomized controlled trial of low-dose aspirin in Japanese patients with type 2 diabetes. PARTICIPANTS This study enrolled 2536 patients with type 2 diabetes, age 30-85 years, and no history of atherosclerotic cardiovascular disease, from December 2002 until May 2005. All participants recruited in the JPAD trial were followed until the day of any fatal event or July 2015. We defined participants taking any statin at enrollment as the statin group (n = 650) and the remainder as the no-statin group (n = 1886). MAIN MEASURES The primary end point was the first occurrence of any cancer (cancer incidence). The secondary end point was death from any cancer (cancer mortality). KEY RESULTS During follow-up (median, 10.7 years), 318 participants developed a new cancer and 123 died as a result. Cancer incidence and mortality were 10.5 and 3.7 per 1000 person-years in the statin group, and 16.8 and 6.3 per 1000 person-years in the no-statin group, respectively. Statin use was associated with significantly reduced cancer incidence and mortality after adjustment for confounding factors (cancer incidence: adjusted hazard ratio [HR], 0.67; 95% CI, 0.49-0.90, P = 0.007; cancer mortality: adjusted HR, 0.60; 95% CI, 0.36-0.98, P = 0.04). CONCLUSIONS Statin use was associated with a reduced incidence and mortality of cancer in Japanese patients with type 2 diabetes.

Abstract
Background:
From the early phase of the Coronavirus disease-2019 (COVID-19) pandemic, cardiologists have paid attention not only to COVID-19-associated cardiovascular sequelae, but also to treatment strategies for rescheduling non-urgent procedures. The chief objective of this study was to explore confirmed COVID-19 cardiology case experiences and departmental policies, and their regional heterogeneity in Japan. Methods and Results:
We performed a retrospective analysis of a nationwide survey performed by the Japanese Circulation Society on April 13, 2020. The questionnaire included cardiology department experience with confirmed COVID-19 cases and restriction policies, and was sent to 1,360 certified cardiology training hospitals. Descriptive analysis and spatial autocorrelation analysis of each response were performed to reveal the heterogeneity of departmental policies. The response rate was 56.8% (773 replies). Only 16% of all responding hospitals experienced a COVID-19 cardiology case. High-risk procedures were restricted in more than one-fifth of hospitals, including transesophageal echocardiography (34.9%) and scheduled catheterization (39.5%). The presence of a cardiologist in the COVID-19 team, the number of board-certified cardiologists, any medical resource shortage and a state of emergency were positively correlated with any type of restriction. Conclusions:
We found both low clinical case experiences with COVID-19 and restrictions of cardiovascular procedures during the first COVID-19 wave in Japan. Restrictions arising as a result of COVID-19 were affected by hospital- and country-level variables, such as a state of emergency.
