Background: The accurate sensitivity of amyloid deposition in extracardiac tissue (subcutaneous tissue and gastrointestinal tract) has not been evaluated in transthyretin amyloidosis cardiomyopathy (ATTR-CM) patients. This study aimed to evaluate the sensitivity of amyloid deposition in obtained endomyocardial and extracardiac biopsies.Methods and Results: This study retrospectively evaluated 175 consecutive ATTR-CM patients (wild-type [ATTRwt]: 134, hereditary [ATTRv]: 41) who had positive findings on 99 mTc-labeled pyrophosphate (99 mTc-PYP) scintigraphy and underwent tissue biopsy of at least one organ (subcutaneous tissue, gastrointestinal tract, and endomyocardium). Amyloid deposition was observed in the subcutaneous tissue of 57/150 patients (38%), gastrointestinal tract of 80/131 patients (61%), and endomyocardium of 108/109 patients (99%). Compared to patients with ATTRv, ATTRwt had significantly lower sensitivity in subcutaneous tissue (73% vs. 25%, P<0.01) and tended to be lower in the gastrointestinal tract (74% vs. 57%, P=0.08) biopsies. Among 124 patients who underwent both subcutaneous tissue and gastrointestinal tract biopsies, amyloid was detected in at least 1 specimen in 91 (73%) patients. The sensitivity of the combination of extracardiac biopsies was 66% and 94% in ATTRwt-CM and ATTRv-CM, respectively. Multivariate analysis reveals that ATTRv was the only significant predictor of amyloid deposition in the subcutaneous tissue.Conclusions: Subcutaneous tissue and gastrointestinal tract biopsy sensitivity are inadequate, especially in patients with ATTRwt; however, the combination of these extracardiac biopsies contributes to increased sensitivity in patients with positive 99 mTc-PYP scintigraphy findings.

Background:The complication of left ventricular (LV) hypertrophy (LVH) is associated with increased incidence of major cardiovascular events. Hypertension is an independent risk factor among several factors contributing to the development of LVH, and thus appropriate treatment of both hypertension and LVH reduces the risk of developing heart failure. Mineralocorticoid-receptor blockers (MRBs) have been reported to improve the prognosis of LVH, but use of currently available MRBs is limited by adverse events. Esaxerenone is a novel selective nonsteroidal MRB recently approved for treatment of hypertension. Although the renoprotective effect of esaxerenone has been demonstrated in both preclinical and clinical studies, little data is available in terms of its cardioprotective effects.Methods and Results:This multicenter, open-label, exploratory interventional study was designed to evaluate the safety and efficacy of esaxerenone in combination with renin-angiotensin system (RAS) inhibitors or calcium-channel blockers (CCBs). Eligible criteria are hypertensive patients with LVH, and target blood pressure (BP) not reached with an RAS inhibitor or a CCB. The primary endpoints are change from baseline in seated home BP (early morning systolic/diastolic BPs), and change and %change from baseline in the LV mass index at the end of treatment.Conclusions:This study will provide the first clinical evidence of the antihypertensive effect and safety of esaxerenone in hypertensive patients with LVH.

Background: After previous earthquakes, a high prevalence of deep vein thrombosis (DVT) has been reported. We examined DVT prevalence and risk factors in evacuees of the Kumamoto earthquakes by performing mobile DVT screening at various evacuation centers around the epicenter. Methods and Results: For 1 month after the Kumamoto earthquake on 14 April 2016, mobile DVT screening using portable ultrasonography (US) was performed at 80 evacuation centers. Questionnaires, physical examination, and US of the lower limb were carried out, and simple D-dimer measurements were undertaken for DVT-positive examinees. The total number of examinees was 1,673, of whom 178 (10.6%) had DVT. The prevalence of DVT seemed to be gradually decreasing in the screening period, but age, use of sleep medication, prevalence of hypertension, dyslipidemia, leg edema, and lower leg varix were significantly higher in the DVT positive group than in the negative group. On multivariable logistic regression analysis, high age (≥70 years old), use of sleep medication, lower leg edema, and lower leg varix were significant predictors of DVT. In examinees with these 4 predictors, the DVT positive rate was 71.4%. Conclusions: In the first month after the Kumamoto earthquakes, DVT prevalence and severity, evaluated on D-dimer level, decreased with the passage of time. Mobile DVT screening indicated significant factors stratifying DVT risk in the evacuees.

Aims: Royal jelly, a creamy substance secreted by honeybees, has been reported to have beneficial effects against dyslipidemia and metabolic syndrome. However, the effects of royal jelly on atherogenesis remain unknown. Hence, we prospectively evaluated whether royal jelly augments vascular endothelial function, which can reflect early atherogenesis, in healthy volunteers. Methods: This was a single-center, double-blind, 1:1 randomized placebo-controlled study conducted from October 2018 to December 2019. A total of 100 healthy volunteers were randomly assigned to receive either royal jelly 690 mg or placebo daily for 4 weeks. The primary endpoint was augmentation in vascular endothelial function as assessed using the change in the reactive hyperemia peripheral arterial tonometry index (RH-PAT) index, and the secondary endpoints were the changes in liver function and lipid profiles between baseline and 4 weeks after enrollment. Results: The mean age of the participants was 35.0±9.3 years in the placebo group and 36.1±9.1 years in the royal jelly groups; 45% and 50% of the placebo and the royal jelly groups, respectively, were male. The percentage relative change in the RH-PAT index was significantly higher in the royal jelly group than in the placebo group (21.4%±53.1% vs. 0.05%±40.9%, P=0.037). The percentage relative changes in alanine aminotransferase and γ-glutamyl transpeptidase were significantly lower in the royal jelly group than in the placebo group (alanine aminotransferase: −6.06%±22.2% vs. 11.6%±46.5%, P=0.02; γ-glutamyl transpeptidase: −3.45%±17.8% vs. 4.62%±19.4%, P=0.045). Lipid profiles were not significantly different between the two groups. Conclusions: Royal jelly might have antiatherogenic property by improving vascular endothelial function. It also augmented liver functions in healthy volunteers.

Background:Using transthoracic echocardiography, including 2D speckle tracking imaging (STI), this study examined cardiac function after domino liver transplantation (DLT) with liver grafts explanted from patients with hereditary amyloidogenic transthyretin amyloidosis.Methods and Results:In all, 14 patients who underwent DLT at Kumamoto University Hospital and for whom 2D STI information was available were enrolled in the study; time-dependent echocardiographic changes were evaluated in 7. Although left ventricular (LV) systolic and diastolic function did not differ between the pre- and post-DLT periods (mean [±SD] 5.4±1.0 years after DLT), there were significant (P<0.05 for all) increases in the post- vs. pre-DLT period in basal longitudinal strain (LS; −13.4±2.3 vs. −19.3±4.4), relative apical LS index (=apical LS/[basal LS+mid LS]; 0.75±0.20 vs. 0.58±0.08), and LV ejection fraction/global LS (3.91±0.58 vs. 3.06±0.44). Age at the time of DLT was significantly higher in the group with impaired (>−14%) than preserved basal LS (57.2±3.5 vs. 39.6±16.0 years; P<0.05). When control subjects (n=14) were added to the enrolled DLT recipients, multivariable logistic regression analysis revealed that a history of DLT was significantly associated with impaired basal LS (>−14%; odds ratio 28.39, 95% confidence interval 1.89–427.45, P<0.05).Conclusions:LV systolic and diastolic function was preserved in the long term after DLT. However, 2D STI revealed subtle cardiac dysfunction in DLT recipients, which may be an early manifestation of cardiac amyloidosis.

Background:There are few reports on current awareness and status of transthoracic echocardiography (TTE), including the actual performance rate according to echocardiographic guidelines, in a specific area or region.Methods and Results:This cross-sectional survey study was conducted in Kumamoto Prefecture from October 2018 to March 2019. There are 366 medical institutions advocating cardiology in Kumamoto Prefecture. Of these, 259 (101 hospitals and 158 clinics) returned questionnaires regarding TTE. In all, 150,570 TTEs were performed in 2017. Of these, 132,771 (88%) were performed in hospitals and 17,799 (12%) were performed in clinics. Physicians performed only 5% of TTEs, whereas sonographers performed 86%. Although the modified Simpson method was performed in 90% of hospitals, 3-dimensional echocardiography was performed in only 2% of hospitals. In addition, the left atrial volume index was not examined in approximately 60% of hospitals, and the mean E/E′ ratio was not examined in 80% of hospitals. Multivariable logistic regression analysis revealed that having a Fellow of the Japan Society of Ultrasonic in Medicine was significantly and independently associated with guideline-oriented TTE (odds ratio 9.43; 95% confidence interval 1.22–72.71, P<0.05).Conclusions:The rate of echocardiographic measurements performed according to echocardiographic guidelines is exceptionally low in Kumamoto Prefecture. Sufficient dissemination of echocardiographic guidelines may be important in improving this rate.

The 79thAnnual Scientific Meeting of the Japanese Circulation Society was held in Osaka on April 24–26, 2015. The main theme was “Late-breaking Cardiovascular Medicine from Japan”. Recently, optimal medical treatment has been guided by evidence-based medicine. We aim to emphasize the research findings and advances in cardiology from Japan, in the hope that Japan will become one of the leaders in the field worldwide. Unlike previous meetings, this annual scientific meeting was held in late April. Approximately 18,000 people, including medical doctors, healthcare professionals, and management staff, attended. The meeting was successfully completed, and included discussions on state-of-the art medicine.
