Abstract
BACKGROUND Transthoracic impedance values have not been widely used to measure extravascular pulmonary water content due to accuracy and complexity concerns. Our aim was to develop a foundational model for a novel system aiming to non-invasively estimate the intrathoracic condition of heart failure patients. METHODS We employed multi-frequency bioelectrical impedance analysis to simultaneously measure multiple frequencies, collecting electrical, physical, and hematological data from 63 hospitalized heart failure patients and 82 healthy volunteers. Measurements were taken upon admission and after treatment, and longitudinal analysis was conducted. RESULTS Using a light gradient boosting machine, and a decision tree-based machine learning method, we developed an intrathoracic estimation model based on electrical measurements and clinical findings. Out of the 286 features collected, the model utilized 16 features. Notably, the developed model demonstrated high accuracy in discriminating patients with pleural effusion, achieving an area under the receiver characteristic curves (AUC) of 0.905 (95% CI: 0.870-0.940, p < 0.0001) in the cross-validation test. The accuracy significantly outperformed the conventional frequency-based method with an AUC of 0.740 (95% CI: 0.688-0.792, and p < 0.0001). CONCLUSIONS Our findings indicate the potential of machine learning and transthoracic impedance measurements for estimating pleural effusion. By incorporating noninvasive and easily obtainable clinical and laboratory findings, this approach offers an effective means of assessing intrathoracic conditions.

Abstract
AIMS To examine the effects of a 24-month treatment with ipragliflozin on carotid intima-media thickness (IMT) in type 2 diabetes patients. METHODS AND RESULTS In this multicenter, prospective, randomized, open-label, and blinded-endpoint investigator-initiated clinical trial, adults with type 2 diabetes and haemoglobin A1C (HbA1c) of 6.0-10.0% (42-86 mmol/mol) were randomized equally to ipragliflozin (50 mg daily) and non-sodium-glucose cotransporter-2 (SGLT2) inhibitor use of standard-care (control group) for type 2 diabetes and were followed-up to 24 months. The primary endpoint was the change in mean common carotid artery IMT (CCA-IMT) from baseline to 24 months. A total of 482 patients were equally allocated to the ipragliflozin (N = 241) and control (N = 241) groups, and 464 patients (median age 68 years, female 31.7%, median type 2 diabetes duration 8 years, median HbA1c 7.3%) were included in the analyses. For the primary endpoint, the changes in the mean CCA-IMT from baseline to 24 months were 0.0013 [95% confidence interval (CI), -0.0155-0.0182] mm and 0.0015 (95% CI, -0.0155-0.0184) mm in the ipragliflozin and control groups, respectively, with an estimated group difference (ipragliflozin-control) of -0.0001 mm (95% CI, -0.0191-0.0189; P = 0.989). A group difference in HbA1c change at 24 months was also non-significant between the treatment groups [-0.1% (95% CI, -0.2-0.1); P = 0.359]. CONCLUSION Twenty-four months of ipragliflozin treatment did not affect carotid IMT status in patients with type 2 diabetes recruited in the PROTECT study, relative to the non-SGLT2 inhibitor-use standard care for type 2 diabetes.

Abstract
A 67-year-old man, hospitalized with fever and pancytopenia, experienced cardiogenic shock on the 3rd day of hospitalization. He complained of chest pain and exhibited cardiac dysfunction, upregulated serum troponin levels, and an ST elevation on electrocardiogram. Severe fever with thrombocytopenia syndrome (SFTS) was suspected based on the symptom course after a tick bite and was definitively diagnosed using the serum polymerase chain reaction (PCR) test. An endomyocardial biopsy performed in the convalescent phase revealed a sign of myocardial inflammation with increases in CD3- and CD68-positive cells. We herein report the first case of acute myocarditis complicated with SFTS.

Abstract
Arrhythmogenic cardiomyopathy (ACM) caused by TMEM43 p.S358L is a fully penetrant heart disease that results in impaired cardiac function or fatal arrhythmia. However, the molecular mechanism of ACM caused by the TMEM43 variant has not yet been fully elucidated. In this study, we generated knock-in (KI) rats harboring a Tmem43 p.S358L mutation and established induced pluripotent stem cells (iPSCs) from patients based on the identification of TMEM43 p.S358L variant from a family with ACM. The Tmem43-S358L KI rats exhibited ventricular arrhythmia and fibrotic myocardial replacement in the subepicardium, which recapitulated the human ACM phenotype. The four-transmembrane protein TMEM43 with the p.S358L variant (TMEM43S358L ) was found to be modified by N-linked glycosylation in both KI rat cardiomyocytes and patient-specific iPSC-derived cardiomyocytes. TMEM43S358L glycosylation increased under the conditions of enhanced endoplasmic reticulum (ER) stress caused by pharmacological stimulation or age-dependent decline of the ER function. Intriguingly, the specific glycosylation of TMEM43S358L resulted from the altered membrane topology of TMEM43. Moreover, unlike TMEM43WT , which is mainly localized to the ER, TMEM43S358L accumulated at the nuclear envelope of cardiomyocytes with the increase in glycosylation. Finally, our comprehensive transcriptomic analysis demonstrated that the regional differences in gene expression patterns between the inner and outer layers observed in the wild type myocardium were partially diminished in the KI myocardium prior to exhibiting histological changes indicative of ACM. Altogether, these findings suggest that the aberrant accumulation of TMEM43S358L underlies the pathogenesis of ACM caused by TMEM43 p.S358L variant by affecting the transmural gene expression within the myocardium.

Abstract
Background: Chronic limb-threatening ischemia (CLTI) is the most advanced stage of peripheral artery disease. Therefore, a multidisciplinary approach is necessary to avoid major amputation in CLTI patients. Malnutrition worsens the condition of CLTI patients, and therefore, it may be important to evaluate the nutritional status in patients with CLTI. This study was designed to evaluate the baseline patient characteristics and the influence of the controlling nutritional status (CONUT) score on the clinical results. Method and Results: A retrospective, single-center, non-randomized study was conducted to evaluate the associations of death, major amputation, and wound healing rate at 12 months with the CONUT score on admission. Consecutive CLTI patients (mean age 73.2 ± 10.4 years; 84 males) who underwent endovascular therapy (EVT) for infra-popliteal lesions at Fukuoka University Hospital from January 2014 to May 2019 were enrolled and divided into two groups (higher and lower CONUT score groups). The higher CONUT group showed a higher percentage of dialysis (66.7% vs. 33.9%, p < 0.001) and a higher clinical frailty scale (5.9 ± 1.4 vs. 4.9 ± 1.9, p = 0.005) than the lower CONUT group. Rates of amputation-free survival were 89.5% and 69.8% in the lower and higher CONUT groups, respectively. In addition, rates of wound healing at 12 months were 98.0% and 78.3% in the lower and higher CONUT groups, respectively. Multivariate regression analysis demonstrated that a higher CONUT score was an independent predictor for delayed wound healing (OR: 11.2; 95% CI: 1.29–97.5; p = 0.028). Conclusion: An assessment of the nutritional status using the CONUT score could be useful for predicting wound healing, and earlier nutritional intervention may improve the outcome of CLTI patients. Early examination and treatment, along with raising awareness of the issue, may be important for improving the prognosis.

Abstract
A healthy 35-year-old man was admitted to a rural hospital with coronavirus disease (COVID-19). During 14 days of hospitalization, he had no symptoms and was not given supplemental oxygen. About 3 weeks after discharge, he was re-admitted to the same hospital with new-onset continuous fever and general weakness. At the time of his second admission, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) RT-PCR was performed on a retro-nasal swab and the result was negative. Four days after admission, the patient was transferred to our intensive care unit (ICU) following deterioration of his respiratory and haemodynamic conditions, where he received mechanical ventilation, intra-aortic balloon pumping, and veno-arterial extracorporeal membrane oxygenation. A nasopharyngeal swab was obtained again at ICU admission, but RT-PCR was negative for SARS-CoV-2. All antibody titres measured against other viruses were low. Blood cultures were negative, and no bacteria were observed in sputum samples. However, SARS-CoV-2 RNA was detected by RT-PCR from sections obtained by myocardial biopsy. The patient's final diagnosis was delayed-onset SARS-CoV-2-induced fulminant myocarditis (FM). We strongly suggested that one of the proposed mechanisms of COVID-19-related myocardial injury will be the direct invasion of SARS-CoV-2 into cardiomyocytes even if delayed-onset. And this is the first case of delayed-onset FM in which diagnosis of active myocarditis was proven by pathological examination following endomyocardial biopsy and SARS-CoV-2 was detected in the myocardium by RT-PCR.

Abstract
BACKGROUND Mitral annulus calcification (MAC) has been associated with cardiovascular diseases, including heart failure (HF); however, the associations between MAC and both the category and etiology of HF have not been fully elucidated. The aim of this study was to investigate the relationship between MAC and three types of HF rehospitalization: HF with preserved ejection fraction (HFpEF), HF with mid-range EF (HFmrEF), and HF with reduced EF (HFrEF). METHODS We enrolled consecutive patients undergoing echocardiography, who were admitted to our hospital for clinically indicated congestive HF between April 2014 and March 2018. Cox proportional-hazards models were used after adjusting for age, gender, and hypertension. RESULTS Of 353 patients, 40 (11.3%) had MAC. With a median follow-up of 2.8 years, 100 (28%) patients were rehospitalized for congestive HF (HFpEF 40%, HFmrEF 16%, HFrEF 44%, respectively). According to the Kaplan-Meier method, the estimated incidence of HFpEF rehospitalization in the MAC group was significantly greater than that in the non-MAC group (p < 0.001) whereas the incidences of HFmrEF and HFrEF rehospitalization were comparable between the groups (p = 0.101 and p = .291, respectively). In a multivariate analysis, MAC remained significantly associated with HFpEF rehospitalization (hazard ratio: 3.379; 95% confidence interval: 1.651-6.597). At initial HF hospitalization, E/e' was significantly higher in the MAC group (both septum and lateral, p < 0.05), suggesting a possible relationship between MAC and left ventricular diastolic function. CONCLUSIONS Mitral annulus calcification was associated with increased HFpEF rehospitalization and might be a cause of left ventricular diastolic dysfunction.

Abstract
Background: Drug-coated balloon strategies in endovascular therapy often result in severe dissection, so lesion preparation must be improved. We evaluated the efficacy of a gradual inflation method, termed "super slow inflation" (SSI), in preparing lesions to avoid severe dissections. Methods and Results: The association between balloon pressure and the dilatation of a model constricted vessel, as well as the load applied to the balloon surface, were determined using a burst leak detector for a quick inflation (QI; 1 atm/s) protocol and SSI (1 atm/20 s). A retrospective, single-center, non-randomized study evaluated differences in vessel dissection patterns after balloon angioplasty depending on inflation method in 81 consecutive patients (mean [±SD] age 74.6±9.2 years; 54 males) who underwent balloon angioplasty for de novo femoropopliteal lesions between January 2017 and March 2019. In the constricted vessel model, vessel dilatation increased gradually using SSI, with the maximum dilatation load being approximately 100 g lower for the SSI than QI protocol. In patients, the rate of severe vessel dissection was significantly lower in the SSI than non-SSI group (17.6% vs. 55.2%, respectively; P<0.001). Multivariate regression analysis revealed that SSI was an independent factor preventing severe dissection (odds ratio 0.18; 95% confidence interval 0.06-0.53; P=0.002). Conclusions: SSI is a gentle and effective method for the preparation of femoropopliteal lesions to reduce the incidence of severe angiographic dissection when using drug-coated balloons.

Abstract
An 81-year-old man presented with shortness of breath and was referred to our hospital with suspected acute pulmonary embolism. Enhanced computed tomography revealed a right aberrant subclavian artery with a thrombosed Kommerell diverticulum (KD), as well as deep vein thrombosis in the left leg and bilateral pulmonary artery thrombosis. Thrombosis in the KD disappeared after one month of anticoagulation treatment with rivaroxaban. Thrombosis of a KD is a rare condition that may cause distal emboli and subclavian steal syndrome, although this syndrome was not present in this case. Rivaroxaban is an effective anticoagulant for treating thrombosis of a KD.

Abstract
Objective Cardiac rehabilitation (CR) improves the mortality in patients with cardiovascular disease (CVD). Even in elderly patients with CVD, CR may improve the activities of daily living (ADL). Methods Eighty-eight outpatients over 65 years of age at the beginning of a CR program (baseline) at Fukuoka University Hospital who had CVD and could be followed-up for up to 5 years were enrolled. CVD included ischemic heart disease, postoperative valvular heart disease, dissecting aneurysm of the aorta and peripheral artery disease. The patients were divided into 2 groups according to the average estimated glomerular filtration rate (eGFR) at baseline (55.4±14.8 mL/min/1.73 m2): high (≥55.4, n=44) and low (<55.4, n=44)-eGFR groups. The anaerobic threshold (AT) during exercise and left ventricular ejection fraction (LVEF) were measured by cardiopulmonary exercise (CPX) and ultrasound cardiography, respectively. The serum brain natriuretic protein (BNP) was also measured every year. Results The average age at baseline in all patients was 73±6 years. In all patients, the level of eGFR did not significantly change for 5 years (55±15 mL/min/1.73 m2 at baseline vs. 48±14 at the end of the study). The AT (3.7±1.0 METs at baseline vs. 3.3±0.5), LVEF (57±13% vs. 64±10%) and BNP (260±452 pg/mL vs. 308±345) were also maintained for 5 years. In both the low- and high-eGFR groups, the eGFR, AT during exercise, LVEF and BNP at the end of the study were not significantly changed compared to the baseline values, although some changes were observed during the follow-up period. Conclusion Long-term CR in CVD outpatients over 65 years of age helped maintain the AT, LVEF, BNP and eGFR for 5 years. CR afforded cardio-renal protection in elderly patients with CVD.

Abstract
BACKGROUND Cardiac rehabilitation (CR) is an essential component of care for patients with cardiovascular diseases (CVD). We aimed to evaluate clinical outcomes in outpatients with CVD who did and did not complete a 5-month CR program. METHODS Three hundred thirty-two outpatients with CVD who participated in a 5-month CR program and were followed-up for maximum 5 years were registered. We divided the patients into two groups: those who completed the CR program (success group, n = 175) and those who could not (non-success group, n = 157). Both long-term (5 years) and short-term (5 months) clinical outcomes were compared between the two groups. RESULTS There were no significant differences in patient characteristics at baseline between the success and non-success groups. With regard to both long-term and short-term clinical outcomes, the rates of all-cause death and hospital admission in the success group were significantly lower than those in the non-success group by a Kaplan-Meier analysis. There was a significant difference in short-term CVD death and hospital admission between the groups, but not for long-term CVD death and hospital. In long-term period, all-cause death and hospital admission was independently associated with completion of the CR program in addition to the presence of peripheral artery disease and VE vs. VCO2 slope after adjusting for age, gender, body mass index, types of CVD and medications. CONCLUSIONS Completion of a 5-month CR program was associated with the prevention of all-cause death and hospital admission, but not CVD death and hospital admission in the long-term, which suggests that we need to reconsider this issue.

Abstract
Background We analyzed what kind of lifestyle modification first-year university students need based on the results of a health-consciousness survey conducted in first-year students immediately after they entered a university. Methods This population-based cross-sectional study used a “questionnaire survey on lifestyle and health for promoting health” conducted in Japan in 2015. From among an initial pool of 3,912 students, we excluded 314 due to insufficient data. The remaining 3,598 students (2,206 males and 1,392 females) were divided into four groups according to body mass index (BMI) based on Japan Society for the Study of Obesity “Guidelines for the management of obesity disease 2016”: low (18.5 > BMI), less than standard (22.0 > BMI ≥ 18.5), standard or higher (25.0 > BMI ≥ 22.0) and obesity (BMI ≥ 25.0). Results Females had an ideal body image that was at a lower body weight regardless of their BMI. Males in the low BMI and obesity groups tended to be less aware of health issues. For each level of BMI, and in both males and females, the most frequent report of stress was “sometimes feel”. The most frequent method for relieving stress was spending time with friends. Among males, those in the obesity group spent more time with “personal computers, televisions and games, etc.” in a sitting position. When students were asked to rank which of their lifestyle habits needed the most improvement, “lack of exercise” was the highest, followed by “irregular schedule” and “dietary habits”. In daily living behavior, a significant difference was observed for “exercise” among males, but not females. Conclusion The attitudes of both males and females regarding the importance of physical activity and the necessity of efforts to improve health are presented. Health education for university students based on the attitudes may be useful for the prevention of lifestyle-related diseases for themselves in the future and before they become parents.

Abstract
We evaluated whether comprehensive cardiac rehabilitation (CR) in patients with cardiovascular disease (CVD) could improve various hemodynamic parameters obtained using simple non-invasive tests. We analyzed 48 CVD patients with (n = 38, CR group) or without (n = 10, non-CR group) a CR program, and prospectively followed them for 12 months. Various parameters were measured at baseline and after 12 months using 3 simple non-invasive tests: blood pressure (BP) and severity of atherosclerosis [arterial velocity pulse index (AVI) and atrial pressure volume index] were determined using PASESA®, an index of total autonomic nerve activity and a coefficient of variation of the R-R interval (CVRR) were determined using eHEART®, and the total peripheral resistance, stroke volume and cardiac index (CI) were determined using nico®. The main hemodynamic parameters did not change between baseline and 12 months in both groups. Patients in the CR group were divided into higher (H-) and lower (L-) systolic BP (SBP) or AVI according to the average value of SBP or AVI at baseline in the CR group. Patients with H-SBP or H-AVI in the CR group showed a significant reduction of SBP or AVI at 12 months. In addition, patients in the CR group were divided into H- and L- CI or CVRR according to the average value of CI or CVRR at baseline in the CR group. Patients with L-CI or L-CVRR in the CR group significantly improved after 12 months. In conclusion, CR may lead various hemodynamic parameters obtained using simple non-invasive tests to their appropriate levels.

Abstract
Background In our experience, the change in body weight (BW) during hospitalization varies greatly in patients with acute decompensated heart failure (HF). Since the clinical significance of a change in BW is not clear, we investigated whether a change in BW could predict mortality. Methods We retrospectively enrolled 130 patients (72 males; aged 68 ± 10 years) who were hospitalized due to acute decompensated HF and followed for 2 years after discharge. The change in the BW index during hospitalization (ΔBWI) was calculated as (BW at hospital admission minus BW at hospital discharge)/body surface area at hospital discharge. Results The patients were divided into quartiles according to ΔBWI, and the 2-year mortality rates in the quartiles with the lowest, second, third and highest ΔBWI were 18.8%, 12.1%, 3.1% and 9.1%, respectively. In a multivariate Cox proportional hazards analysis after adjusting for variables with a P value less than 0.05, ΔBWI was independently associated with 2-year mortality (P = 0.0002), and the quartile with the lowest ΔBWI had a higher relative risk (RR) for 2-year mortality than the quartile with the highest ΔBWI (RR: 7.46, 95% confidence interval: 1.03 - 53.99, P = 0.04). Conclusion In conclusion, ΔBWI was significantly associated with 2-year mortality after discharge, which indicates that ΔBWI might be a simple predictor of prognosis in acute decompensated HF.

Abstract
Background Many patients continue to have high blood pressure (BP) even after treatment with high-dose (H)-angiotensin II type 1 receptor blocker (ARB)/calcium channel blocker (CCB) or middle-dose (M)-ARB/CCB/hydrochlorothiazide (HCTZ). Methods Thirty-two hypertensive patients who had the use of H-ARB/CCB or M-ARB/CCB/HCTZ were enrolled in this study. We applied a changeover with a switch to H-ARB (telmisartan 80 mg/day)/CCB (amlodipine 5 mg/day or nifedipine CR 40 mg/day)/HCTZ (12.5 mg/day). Results Systolic BP (SBP) and diastolic BP (DBP) were significantly decreased in all patients and in the H-ARB/CCB and M-ARB/CCB/HCTZ groups after 3 months. Percentage (%) of patients who reached the target BP after 3 months (72%) in all patients was significantly higher than that at 0 months (19%). There were no serious adverse effects in any of the patients. Conclusions Combination therapy with H-ARB/CCB/HCTZ was associated with a significant reduction of BP.

Abstract
Visit-to-visit variability (VVV) in blood pressure (BP) has been shown to be a predictor of cardiovascular events. It is unknown whether CR can improve VVV in BP as well as reducing BP. We enrolled 84 patients who had cardiovascular disease (CVD) and participated in a 3-month CR program. We measured systolic and diastolic BP (SBP and DBP), pulse pressure (PP), and heart rate (HR) before exercise training at each visit and determined VVV in BP or HR expressed as the standard deviation of the average BP or HR. Patients who had uncontrolled BP at baseline and who did not change their antihypertensive drugs throughout the study period showed a significant reduction of both SBP and DBP with a decrease in PP after 3 months. Patients who did not change their antihypertensive drugs were divided into larger (L-) and smaller (S-) VVV in the SBP groups and L- and S-VVV in the DBP groups according to the average value of VVV in SBP or DBP. In the L-VVV in the SBP and DBP groups, VVV in SBP and DBP in the 1st month was significantly decreased after the 3rd month in both groups. HR at baseline was significantly decreased after 3 months. In addition, CR induced a significant increase in the level of high-density lipoprotein cholesterol (HDL-C) in blood. In conclusion, CR improved VVV in BP in patients with L-VVV in BP and evoked a significant reduction in HR and an increase in HDL-C. These effects due to the CR program may be cardioprotective.

Abstract
Background We compared the efficacy and safety of azilsartan to those of olmesartan in a prospective, randomized clinical trial. Methods Forty-four hypertensive patients who had coronary artery disease (CAD) were enrolled. We randomly assigned patients to changeover from their prior angiotensin II receptor blockers (ARBs) to either azilsartan or olmesartan, and followed the patients for 12 weeks. Results Office systolic blood pressure (SBP) in the azilsartan group was significantly decreased after 12 weeks. SBP and diastolic blood pressure (DBP) after 12 weeks in the azilsartan group were significantly lower than those in the olmesartan group. The percentage of patients who reached the target BP at 12 weeks (78%) in the azilsartan group was significantly higher than that at 12 weeks (45%) in the olmesartan group. There were no significant changes in pentraxin-3, high-sensitively C-reactive protein or adiponectin in blood after 12 weeks in either group. Although serum levels of creatinine (Cr) in the azilsartan group significantly increased, these changes were within the respective normal range. Conclusion In conclusion, the ability of azilsartan to reduce BP may be superior to that of prior ARBs with equivalent safety in hypertensive patients with CAD.

Abstract
Cardiac rehabilitation (CR) improves cardiac function and exercise capacity in patients with cardiovascular disease (CVD). Simpler techniques are needed for use by physicians in the examination room to assess the usefulness of CR. We enrolled 46 consecutive CVD patients in a CR program (CR group) and prospectively followed them for 3 months. We compared them to 18 age-, gender- and body mass index-matched CVD patients without CR (non-CR group). Various parameters were measured at baseline and after 3 months using 3 simple non-invasive tests: severity of atherosclerosis [arterial velocity pulse index and arterial pressure volume index (API)] were determined using PASESA®, an autonomic nerve total activity amount index and a coefficient of variation of the R–R interval (CVRR) were determined using eHEART®, and peripheral resistance index, pressure rate product, stroke volume and cardiac index were determined using nico®]. There were no significant differences in patient characteristics including percentages (%) of ischemic heart disease and heart failure between the non-CR and CR groups. Systolic blood pressure (SBP), diastolic BP, heart rate and API at baseline significantly decreased and CVRR at baseline significantly increased after 3 months in the CR group, but not in the non-CR group. In addition, ΔAPI (Δ = the value after 3 months minus the value at baseline) was positively associated with ΔSBP in the CR group. In conclusion, CR significantly decreased BP and improved atherosclerosis and sympathetic nerve activity. These findings suggest that simple non-invasive tests may be useful for assessing the effects of CR.

Abstract
BACKGROUND To improve the clinical outcome of heart failure (HF), it is important to evaluate the etiology and comorbidities of HF. We previously reported the baseline clinical characteristics and medications in hospitalized patients with HF in years 2000 - 2002 (group 2000) and 2007 - 2009 (group 2008). METHODS We conducted a retrospective study of 158 patients who were hospitalized due to HF between 2012 and 2014 (group 2013) in the Department of Cardiology, Fukuoka University Hospital. We analyzed the clinical characteristics and medications at admission and discharge, and compared the findings in group 2013 to those in group 2000 and group 2008. RESULTS The major causes of HF were ischemic heart disease, hypertensive cardiomyopathy, valvular heart disease, and dilated cardiomyopathy. The New York Heart Association classification in group 2013 was significantly higher than those in group 2000 and group 2008. There was no difference in the level of brain natriuretic peptide at admission between group 2008 and group 2013. Tolvaptan began to be administered in group 2013. The median dose of furosemide just before the use of tolvaptan was 40 mg/day. At discharge, group 2013 showed higher rates of β-blocker and aldosterone antagonist. There was no difference in the frequency of loop diuretics. The dose of carvedilol at discharge was only 6.2 ± 4.0 mg/day. Antiarrhythmic drugs and β-blocker were used more frequently in HF with reduced ejection fraction (EF) than in HF with preserved EF. CONCLUSIONS We may be able to improve the clinical outcome of HF by examining the differences in the clinical characteristics and medications at admission and discharge in hospitalized patients with HF.

Abstract
Background Exercise training may improve renal function in patients with chronic kidney disease (CKD). The effect of cardiac rehabilitation (CR) with exercise training on renal function has not yet been established. We evaluated the effects of CR on renal function in patients with cardiovascular disease (CVD). Methods Twenty-three CVD patients in a 1-year CR program (CR group) who had ischemic heart disease (IHD) and/or heart failure were compared with 26 age- and gender-matched CVD patients without CR (non-CR group, standard pharmacological care alone). At baseline and after 1 year, urea nitrogen (UN), creatinine (Cr), potassium (K), estimated glomerular filtration rate (eGFR) and hematocrit (Hct) in blood were assessed. Results There were no differences in the patient characteristics at baseline between the CR and non-CR groups except for the percentages of heart failure and the use of calcium channel blocker. After 1 year, there were no significant changes in UN, Cr, K, eGFR or Hct in either the CR or non-CR groups. The patients in the CR group were divided into two groups according to the eGFR level at baseline: low (n = 12, eGFR < 51 mL/minute/1.73 m2, indicating mild-to-moderate CKD) and high (n = 11, eGFR ≥ 51 mL/minute/1.73 m2) eGFR groups. Although there were no differences in the patient characteristics at baseline between the low and high eGFR groups, the low eGFR group showed a significant increase in eGFR after the 1-year CR program. Conclusions CR may improve renal function in patients with mild-to-moderate CKD.

Abstract
Fifty-four patients were randomly divided into irbesartan and olmesartan groups. Blood pressure (BP) was significantly decreased in all patients at 12 weeks. In particular, BP in patients who initially received irbesartan showed significant reductions. The equality of variance of BP in the irbesartan group was significantly smaller than that in the olmesartan group at 12 weeks. Blood concentrations of adiponectin were significantly increased in the irbesartan group at 12 weeks. Log [pentraxin-3] in the irbesartan group were significantly decreased. In conclusion, the ability of irbesartan to reduce BP is comparable to that of olmesartan with equivalent safety.

Abstract
OBJECTIVE Many patients still have high blood pressure (BP) after treatment with high-dose angiotensin II type 1 receptor blockers (ARBs) or Preminent® (medium-dose of losartan (50 mg/day)/hydrochlorothiazide (HCTZ) (12.5 mg/day)). Therefore, we analyzed whether Micombi®BP (high-dose telmisartan (80 mg/day)/HCTZ (12.5 mg/day)) could provide better results with regard to efficacy and safety for patients with uncontrolled hypertension. METHODS In total, 44 hypertensive patients (22 males, age 71±14 years) who showed uncontrolled BP despite the use of high-dose ARBs or Preminent® were enrolled in this study. We used a changeover design in which the patients were switched from high-dose ARBs or Preminent® to Micombi®BP. We analyzed BP, heart rate (HR), and biochemical parameters before and after treatment for 3 months. RESULTS Systolic BP and diastolic BP significantly decreased (125±15/69±11 mmHg) and 85% of the patients achieved their target BP at 3 months after changeover. Patients who switched from ARBs and those who switched from Preminent® showed similar BP-lowering effects. In addition, the reductions in BP after 3 months in patients with or without chronic kidney disease and in those with or without metabolic syndrome (MetS) were also similar. There were no significant changes in HR during the study period. Although blood levels of potassium, hemoglobin A1c and uric acid (UA) significantly increased after 3 months for all of the patients, none of the patients showed serious adverse effects. CONCLUSION High-dose telmisartan/HCTZ therapy was associated with a significant reduction in BP and helped patients achieve their target BP.

Abstract
A 62-year-old woman complained of sudden chest pain and 64-multidetector row computed tomography (MDCT) was performed. The volume-rendered image showed severe stenosis of the left main coronary trunk artery (LMT). The mean density of the plaque was 32.4 hounsfield units (HU), which indicated soft plaque. Coronary angiography (CAG) showed significant focal stenosis of the LMT. Since the patient had experienced chest pain, and since focal stenosis of the LMT was demonstrated, lipid-lowering therapy using statin and coronary artery bypass graft (CABG, right internal mammary artery-left anterior descending branch, left internal mammary artery-obtuse marginal branch) were applied. Three years after treatment, 64-MDCT showed mild stenosis and a regression of plaque in the LMT. The mean density of the plaque was 73.1 HU (intermediate plaque). CAG showed a degradation of CABG flow, in addition to mild stenosis of the LMT. In conclusion, lipid-lowering therapy with statins may stabilize soft coronary plaque. In addition, non-invasive MDCT is a useful tool for diagnosing coronary artery disease, and for evaluating the size and properties of coronary plaque.

Abstract
BACKGROUND Although plasma pigment epithelium-derived factor (PEDF) levels have been shown to be significantly correlated with the levels of creatinine (Cr) in type 2 diabetes, little is known about the association between PEDF levels and renal dysfunction in patients with coronary artery disease (CAD). METHODS We enrolled 134 consecutive patients with diagnosed CAD and measured plasma levels of PEDF, serum Cr, uric acid (UA) and high-sensitive C-reactive protein (hsCRP). RESULTS Plasma PEDF levels were positively correlated with serum Cr (p 〈 0.0001) and UA (p 〈 0.0001) and negatively correlated with the estimated glomerular filtration rate (eGFR) (p 〈 0.0001), whereas there was no association between plasma PEDF and age or hsCRP. When the subjects were divided into five groups (0-4) according to the number of metabolic factors (obesity, diabetes, hypertension and dyslipidemia), PEDF levels in patients with four factors were significantly higher than those in patients without factors. Next, we divided the patients into quartiles according to their plasma PEDF levels (〈 9.9 μg/mL, 9.9-12.8, 12.9- -15.7, 〉 15.7). The eGFR in the first group was significantly higher than those in the third and fourth groups. Multivariate logistic analysis indicated that eGFR (p 〈 0.0001) and age (p = 0.030) were significant independent variables that correlated with the quartile classification according to PEDF levels. CONCLUSIONS This study revealed that PEDF may play a role in renal dysfunction in CAD patients.

Abstract
Pigment epithelium-derived factor (PEDF) and pentosidine have received growing attention as sensitive biomarkers of the progression of atherosclerosis. The present study was performed to evaluate the utility of these biomarkers for assessing the effects of angiotensin II type 1 receptor blockers (ARBs). Sixty-three patients with coronary artery disease (CAD) following successful stent implantation were divided into an ARB group (n = 50), who initially received valsartan or olmesartan immediately following stent implantation, and a non-ARB group (n = 13) according to their blood pressure (BP) at baseline. Measurement of BP and blood sampling was performed prior to (at baseline) and 6-8 months following stent implantation (at follow-up). There were no significant differences in the baseline characteristics between the groups. Although there were no differences in the percentage of diameter re-stenosis between the groups, the BP level in the ARB group at follow-up showed a significant reduction and reached the target BP. The levels of plasma PEDF were significantly increased at follow-up in the ARB group, but not in the non-ARB group, while there were no differences in the levels of pentosidine between the groups. Changes in BP (ΔBP = BP at follow-up minus BP at baseline) were not associated with ΔPEDF. In conclusion, PEDF may be a useful biomarker for assessing the effects of ARBs independent of a reduction in BP.

Abstract
This study was performed to evaluate the safety and efficacy of additional antihypertensive therapy with angiotensin II type 1 receptor blocker (ARB; olmesartan or valsartan) after successful stent implantation in patients with coronary artery disease (CAD). Fifty patients with CAD after successful stent implantation were included in this study. They were divided into an ARB group, which initially received olmesartan (n=20, 14+/-8 mg day(-1)) or valsartan (n=20, 60+/-23 mg day(-1)) immediately after stent implantation, and a non-ARB group (n=10) according to their blood pressure (BP). Follow-up coronary angiography, measurement of BP and blood sampling were performed before (at baseline) and 6-8 months after stent implantation (at follow-up). There were no significant differences in the baseline characteristics between the groups, except for BP. Although there were no changes in % diameter restenosis between the groups, the BP level in the ARB group at follow-up showed a significant reduction (125+/-12/69+/-9 mm Hg) and reached the target BP. There were no critical adverse effects in the ARB group throughout the study period. In addition, serum high-sensitive C-reactive protein (hs-CRP) and pentraxin 3 were significantly decreased in the ARB group but not in the non-ARB group. Although olmesartan and valsartan induced similar BP-lowering effects, olmesartan but not valsartan induced a significant decrease in hs-CRP, but did not increase serum uric acid. In conclusion, antihypertensive therapy with add-on low-dose ARB after stent implantation was safe and achieved the target BP. In particular, olmesartan had an anti-inflammatory effect.
