Background:The impact of promotional tweets from the official journal account (forCirculation JournalandCirculation Reports) on article viewership has not been thoroughly evaluated.Methods and Results:We retrospectively collected journal viewership data forCirculation JournalandCirculation Reportsfrom March 2021 to August 2021. We compared viewership between articles with (n=15) and without (n=250) tweets. After 1 : 4 propensity score matching (15 tweeted articles and 60 non-tweeted matched controls), journal viewership metrics within 7 days of the tweeting date (and the hypothetical tweeting date), was larger in tweeted articles than non-tweeted articles (median [interquartile range] Abstract page views 89 [60–104] vs. 18 [8–41]).Conclusions:This pilot study suggests a positive relationship between journal-posted promotional tweets and article viewership.

Background: To assist healthcare providers in interpreting guidelines, clinical questions (CQ) are often included, but not always, which can make interpretation difficult for non-expert clinicians. We evaluated the ability of ChatGPT to accurately answer CQs on the Japanese Society of Hypertension Guidelines for the Management of Hypertension (JSH 2019).Methods and Results: We conducted an observational study using data from JSH 2019. The accuracy rate for CQs and limited evidence-based questions of the guidelines (Qs) were evaluated. ChatGPT demonstrated a higher accuracy rate for CQs than for Qs (80% vs. 36%, P value: 0.005).Conclusions: ChatGPT has the potential to be a valuable tool for clinicians in the management of hypertension.

Aim: The prevalence of overweight and a change in atherosclerotic lipid profiles may be linked to region-specific differences in atherosclerotic diseases. We evaluated whether the lipid phenotype could be linked to region- and sex-specific differences in the degree of atherosclerosis.Methods: Non-diabetic subjects included Okinawa (n=1674) and Nagano (n=1392) residents aged 30–75 years who underwent carotid ultrasonography for the measurement of maximum intima-media thickness (max IMT).Results: Average max IMT was higher in Okinawa men and women, and the increase in max IMT with age was enhanced in men. Multiple regression analysis showed that in addition to age and systolic blood pressure, low-density lipoprotein cholesterol and non-high-density lipoprotein cholesterol were IMT determinants only in men for both Okinawa and Nagano. Meanwhile, HDL-cholesterol was a determinant for Okinawa men and women, but not for Nagano men and women.Conclusions: This is the first report to show region- and sex-specific differences in the determinants for max IMT in a Japanese population. The evaluation of the relationship between lipid profile patterns and region- and sex-specific differences in carotid atherosclerosis burden may be required.

Background:The effects of eicosapentaenoic acid (EPA) on coronary artery disease have been previously reported; however, those of the addition of EPA to strong statins on coronary plaque components and local inflammatory cytokines are not known.Methods and Results:A total of 95 patients who had been treated with strong statin for at least 6 months were randomized into 2 groups: an EPA group (additional treatment with EPA at 1,800 mg/day, n=48) or a control group (no additional treatment, n=47), for 6 months. The tissue characteristics of target coronary plaque in each patient were analyzed using IB-IVUS before and after treatment. We also measured plasma levels of inflammatory cytokines sampled in the coronary sinus (CS) and peripheral vein.A significant reduction in lipid volume (18.5±1.3 to 15.0±1.5 mm3, P=0.007) and a significant increase in fibrous volume (22.9±0.8 to 25.6±1.1 mm3, P=0.01) were observed in IB-IVUS image analyses in the EPA group, but no significant changes in the plaque components in the control group. CS levels of pentraxin 3 and monocyte chemoattractant protein-1 were lower after than before treatment with EPA (3.3±2.1 to 2.6±1.2 ng/ml, 120.4±26.2 to 110.2±26.8 pg/ml, P=0.015 and P=0.008, respectively); however, there were no significant changes in those inflammatory cytokines between pre- and post-treatment in the control group.Conclusions:The addition of EPA was associated with reduced lipid volume in coronary plaques and decreased inflammatory cytokines.

Background:The coronary adventitia has recently attracted attention as a source of inflammation because it harbors nutrient blood vessels, termed the vasa vasorum (VV). This study assessed the link between local inflammation in adjacent epicardial adipose tissue (EAT) and coronary arterial atherosclerosis in fresh cadavers.Methods and Results:Lesion characteristics in the left anterior descending coronary artery of 10 fresh cadaveric hearts were evaluated using integrated backscatter intravascular ultrasound (IB-IVUS), and the density of the VV and levels of inflammatory molecules from the adjacent EAT were measured for each of the assessed lesions. The lesions were divided into lipid-rich, lipid-moderate, and lipid-poor groups according to percentage lipid volume assessed by IB-IVUS. Higher expression of inflammatory molecules (i.e., vascular endothelial growth factor A [VEGFA] andVEGFB) was observed in adjacent EAT of lipid-rich (n=11) than in lipid-poor (n=11) lesions (7.99±3.37 vs. 0.45±0.85 arbitrary units [AU], respectively, forVEGFA; 0.27±0.15 vs. 0.11±0.07 AU, respectively, forVEGFB; P<0.05). The density of adventitial VV was greater in lipid-rich than lipid-poor lesions (1.50±0.58% vs. 0.88±0.23%; P<0.05).Conclusions:Lipid-rich coronary plaques are associated with adventitial VV and local inflammation in adjacent EAT in fresh cadavers. This study suggests that local inflammation of EAT is associated with coronary plaque progression via the VV.

Background:Whether preoperative echocardiography improves postoperative outcomes is not well established, so we examined the value of echocardiographic assessment on the onset of postoperative heart failure (HF), and determining which patients benefitted most from undergoing echocardiography prior to major elective non-cardiac surgery.Methods and Results:We identified all patients aged 50 years and older who had major elective non-cardiac surgery, and excluded patients with previously identified severe cardiovascular disease. The primary endpoint was the onset of HF during hospitalization. A total of 806 patients were included in the analysis. During hospitalization, 49 patients (6%) reached the primary endpoint. Within the matched cohort, preoperative echocardiography was associated with a statistically significant decrease in postoperative HF (hazard ratio: 0.46, P=0.01). In subgroup analyses, age, sex, body surface area, hypertension, diabetes mellitus, prior HF, surgical type, chronic kidney disease, pulmonary disease, and malignancy influenced the association of echocardiography with postoperative HF.Conclusions:The use of echocardiography in elderly patients with certain risk factors was associated with improved postoperative outcomes. The basis for this finding remains to be determined; particularly whether echocardiography is simply a marker of a population with better outcomes or whether it leads to better management that improves outcomes.

Background:Patients with type 2 diabetes mellitus (T2DM) show a greater risk for coronary artery disease (CAD), but the risk stratification in asymptomatic CAD patients has not been established. This study investigated the prevalence and severity for asymptomatic CAD and predictors in T2DM patients.Methods and Results:In a multiclinic group, diabetic patients (320 men, 186 women) without known symptoms suggestive of CAD were recruited for multidetector computed tomography (MDCT). Patients were categorized according to severity of coronary atherosclerosis: Grade 1 (normal findings), Grade 2 (mild atherosclerosis without significant stenosis), Grade 3 (moderate stenosis/atherosclerosis, 50–74% stenosis), Grade 4 (moderate stenosis/atherosclerosis, 75–89% stenosis), Grade 5 (severe stenosis/atherosclerosis, ≥90% stenosis). The trend for severity grade of CAD was slightly higher in men than women (P=0.054). For critical lesions (combined Grades 3–5), the prevalence was almost equal (men 44% vs. women 37%; P=0.113). Multivariate models showed that in men, HbA1c≥7.4%, dyslipidemia, duration of diabetes, retinopathy, and other type of cardiovascular diseases were predictors of critical lesions and in women, duration of diabetes and retinopathy were predictors.Conclusions:The prevalence and severity of asymptomatic CAD are comparably high in men and women with T2DM. Risk stratification by using MDCT might be useful to predict asymptomatic coronary lesions requiring coronary revascularization. (Circ J 2015; 79: 2422–2429)

Urinary albumin excretion is a predictor of cardiovascular death. Cardiac rehabilitation (CR) with exercise training (ET) has been shown to improve exercise capacity and prognosis in patients with cardiovascular disease (CVD). However, it remains unclear whether CR reduces urinary albumin excretion in CVD patients. We performed a retrospective, observational study using data obtained from 98 male CVD patients without macroalbuminuria and estimated glomerular filtration rate (eGFR) < 30 mL/minute/1.73 m2 who participated in CR with ET during hospitalization. Twenty-three patients continued supervised ET for 6 months (supervised group) and 75 patients quit supervised ET (non-supervised group). The supervised ET program consisted of 60 minutes of supervised sessions 1-3 times a week and 30-60 minutes of home exercise at least twice a week. Urinary albumin/creatinine ratio (ACR) was significantly decreased in the supervised group at 6 months after enrollment (43 ± 71 mg/g to 17 ± 20 mg/g creatinine, P < 0.05) but not in the non-supervised group. eGFR was unchanged in the supervised group but was significantly decreased in the non-supervised group (72 ± 18 mL/minute/1.73 m2 to 67 ± 17 mL/minute/1.73 m2, P < 0.001). The results of multiple regression analysis showed that only supervised ET was an independent contributor to ΔACR. CR with supervised ET decreased urinary albumin excretion without deterioration of renal function. These findings suggest that continuation of a supervised ET program is associated with reduction in the development of CVD and reduction in cardiovascular morbidity and mortality in CVD patients.

Aim: Recent studies have demonstrated that selective sodium–glucose cotransporter 2 inhibitors (SGLT2is) reduce cardiovascular events, although their mechanism remains obscure. We examined the effect of canagliflozin, an SGLT2i, on atherogenesis and investigated its underlying mechanism. Method: Canagliflozin (30 mg/kg/day) was administered by gavage to streptozotocin-induced diabetic apolipoprotein E-deficient (ApoE-/-) mice. Sudan IV staining was performed at the aortic arch. Immunostaining, quantitative RT-PCR, and vascular reactivity assay were performed using the aorta. In vitro experiments using human umbilical vein endothelial cells (HUVECs) were also performed. Result: Canagliflozin decreased blood glucose (P<0.001) and total cholesterol (P<0.05) levels. Sudan IV staining showed that 12-week canagliflozin treatment decreased atherosclerotic lesions (P<0.05). Further, 8-week canagliflozin treatment ameliorated endothelial dysfunction, as determined by acetylcholine-induced vasodilation (P<0.05), and significantly reduced the expressions of inflammatory molecules such as ICAM-1 and VCAM-1 in the aorta at the RNA and protein levels. Canagliflozin also reduced the expressions of NADPH oxidase subunits such as NOX2 and p22phox in the aorta and reduced urinary excretion of 8-OHdG, suggesting a reduction in oxidative stress. Methylglyoxal, a precursor of advanced glycation end products, increased the expressions of ICAM-1 and p22phox in HUVECs (P<0.05, both). Methylglyoxal also decreased the phosphorylation of eNOSSer1177 and Akt but increased the phosphorylation of eNOSThr495 and p38 MAPK in HUVECs. Conclusion: Canagliflozin prevents endothelial dysfunction and atherogenesis in diabetic ApoE-/- mice. Anti-inflammatory and antioxidative potential due to reduced glucose toxicity to endothelial cells might be its underlying mechanisms.

Sterile chronic inflammation causes cardiometabolic disorders; however, the mechanisms are not fully understood. Previous studies have demonstrated the degradation of cells/tissues in the vasculature and metabolic organs in lifestyle-associated diseases, such as diabetes and hyperlipidemia, suggesting the release and/or accumulation of nucleic acids from damaged cells. DNA is indispensable for life; however, DNA fragments, especially those from pathogens, strongly induce inflammation by the activation of DNA sensors. Growing evidence suggests that DNA-sensing mechanisms, which are normally involved in self-defense against pathogens as the innate immune system, are associated with the progression of inflammatory diseases in response to endogenous DNA fragments. There are several types of DNA sensors in our bodies. Toll-like receptor 9 (TLR9)—one of the most studied DNA sensors—recognizes DNA fragments in endosome. In addition, stimulator of interferon genes (STING), which has recently been extensively investigated, recognizes cyclic GMP-AMP (cGAMP) generated from DNA fragments in the cytosol. Both TLR9 and STING are known to play pivotal roles in host defense as the innate immune system. However, recent studies have indicated that the activation of these DNA sensors in immune cells, such as macrophages, promotes inflammation leading to the development of vascular and metabolic diseases associated with lifestyle. In this review, we discuss recent advances in determining the roles of DNA sensors in these disease contexts. Revealing a novel mechanism of sterile chronic inflammation regulated by DNA sensors might facilitate clinical interventions for these health conditions.

Background:High prevalence of frailty and of diastolic dysfunction (DD) in heart failure and high mortality in frail adults have been noted. We characterized frailty by quantifying differences on echocardiography, and assessed the added prognostic utility of frailty and DD grade in an elderly population.Methods and Results:One hundred and ninety-one patients ≥65 years who had at least 1 cardiovascular risk factor were prospectively recruited for clinically indicated echocardiography at the present institute. Weight loss, exhaustion, and deficits in physical activity, gait speed, and handgrip strength were used to categorize patients as frail (≥3 features), intermediately frail (1 or 2 features), or non-frail (0 features). DD grade ≥2 was defined as severe. Frailty was associated with larger left atrial volume, smaller stroke volume, and worse DD grade after adjustment for age. In a period of 14 months, 29 patients (15%) had cardiovascular events. The addition of frailty score and severe DD significantly improved the prognostic power of a model containing male gender (model 1, male gender, χ2=6.4; model 2, model 1 plus frailty score, χ2=16.7, P=0.004; model 3, model 2 plus severe DD, χ2=25.5, P=0.015).Conclusions:Both frailty and DD grade were significantly associated with future cardiovascular events in an elderly population with preserved ejection fraction and ≥1 risk factor of cardiovascular disease.

We have previously shown that abnormal iron metabolism might be one underlying mechanism of the renal damage observed in the angiotensin II-infused rat. Transforming growth factor-β1 (TGF-β1) is known to play a crucial role in the development of renal damage induced by activation of the renin-angiotensin-aldosterone system. The purpose of the present study was to examine the effects of an iron chelator and a free radical scavenger on the angiotensin II-induced upregulation of TGF-β1 in the kidney. Rats were given angiotensin II (0.7 mg/kg/day) via osmotic minipumps for 7 days. The expressions of the mRNAs of TGF-β1 and collagen types I and IV were significantly increased in response to angiotensin II treatment. Histologic analysis showed that TGF-β1 expression was upregulated mainly in tubular epithelial cells, and occasionally in glomerular and perivascular cells, some of which were identified as monocytes and/or macrophages. Although tubular cells that overexpressed TGF-β1 did not contain iron particles, angiotensin II-induced TGF-β1 upregulation was suppressed by the iron chelator and the free radical scavenger. The free radical scavenger also suppressed angiotensin II-induced upregulation of heme oxygenase-1, an oxidative-stress sensitive gene. By contrast, administration of iron dextran to rats induced upregulation of TGF-β1 mRNA. Collectively, these data suggest that the renal iron overload and presumed subsequent increase in oxidative stress play a role in angiotensin II-induced upregulation of the mRNAs of TGF-β1 and collagen types I and IV in the kidney.
