vated at 43% (Figure C,D). Cardiac computed tomography (CT) was performed using a 256-detector row scanner. Equilibrium phase imaging was acquired 5 min after injection of 100 mL of iodine contrast agent (370 mgI/mL). The ECV was measured with the subtraction method using the precontrast and equilibrium phase images. Cardiac CT showed no coronary artery stenosis. Equilibrium phase imaging showed late iodine enhancement co-located with LGE (Figure E,F). The ECV by CT was 44%, as high as on CMR (Figure G,H). Per histopathology, the patient had A 72-year-old man was referred to hospital because of abnormal ECG, showing poor R wave progression in the precordial leads. Transthoracic echocardiography demonstrated concentric left ventricular hypertrophy, and speckle tracking showed an apical-sparing pattern. Cardiac magnetic resonance imaging (CMR) revealed late gadolinium enhancement (LGE) in the entire subendocardium, which was transmurally exhibited in the hypertrophic septum (Figure A,B). The extracellular volume fraction (ECV) by T1 mapping was remarkably ele-

Background: The prevalence of heart failure (HF) is increasing in aging societies, such as Japan. The current incidence rate (IR) of HF hospitalization in Japan is unknown. Methods and Results: We conducted a regional population-based study assessing the IR of HF hospitalization in Nobeoka City. Data were collected over a period of 3 years from all patients with HF admitted for the first time to hospitals and clinics. 406 HF hospitalizations were registered (54% female; mean age 82 years). The IR of HF hospitalization was 129/100,000 person-years. The difference in the IR between women and men was not significant (131 vs. 127/100,000 person-years, respectively; P=0.767). The age-adjusted IR in the 2015 Japanese population was 105/100,000 person-years. According to 5-year age bands, the IR of HF hospitalization gradually increased up to 60–70 years of age, then increased rapidly in those aged ≥95 years for both sexes. The IR ratio compared with age <65 years was higher in women than men in each older age group. Conclusions: In this population-based study, the current IR of HF hospitalization in a region of Japan was higher than the IR from another study conducted in a different region in early 2000. By presenting detailed age-related data, the research findings will contribute to estimating the number of HF hospitalizations in other areas of Japan.

背景:在老龄化社会，如日本，心力衰竭(HF)的患病率正在上升。目前日本心衰住院的发病率(IR)尚不清楚。方法和结果:我们进行了一项基于区域人群的研究，评估了Nobeoka市HF住院的IR。在3年的时间里收集了所有首次住院和门诊的心衰患者的数据。406例心衰住院登记(54%为女性;平均年龄82岁)。HF住院的IR为129/10万人-年。女性和男性之间的IR差异不显著(分别为131和127/100,000人-年);P = 0.767)。2015年日本人口年龄调整后的IR为105/100,000人年。按5年年龄组划分，60 ~ 70岁HF住院IR逐渐升高，95岁以上HF住院IR迅速升高。与年龄<65岁的人相比，在每个年龄较大的年龄组中，女性的IR比男性高。结论:在这项基于人群的研究中，日本某地区目前HF住院的IR高于2000年初在另一地区进行的另一项研究的IR。通过提供详细的年龄相关数据，研究结果将有助于估计日本其他地区的心衰住院人数。

Background: Diffuse gallbladder (GB) wall thickening is caused by elevated systemic venous pressure, such as heart failure (HF). This study investigated the relationship between GB wall thickness (WT) and HF, and the prognostic impact of GBWT. Methods and Results: This prospective study included 116 patients with HF and 11 healthy controls. Among the 116 patients, 30 with GBWT measurements in the postprandial state or a history and/or signs of GB disease were excluded. The remaining 86 patients had significantly higher GBWT than the controls (median [interquartile range {IQR}] 2.0 [1.7-2.4] vs. 1.3 [1.1-1.6] mm, respectively; P<0.001). GBWT was significantly correlated with B-type natriuretic peptide (r=0.386, P<0.001), left atrial volume index (r=0.452, P<0.001), and tricuspid annular plane systolic excursion (r=-0.311, P=0.006). GBWT also exhibited a stepwise increasing relationship with increasing HF stage (Stage B, 22 patients, median [IQR] 1.8 [1.7-2.1] mm; Stage C, 60 patients, 2.0 [1.8-2.5] mm; and Stage D, 4 patients: 4.0 [3.5-4.5] mm). In Stage C or D HF patients, 11 hospitalizations for HF were observed over a median follow-up of 303 days (IQR 125-394 days). Furthermore, the rate of hospitalization events for HF was significantly higher in the high (≥3 mm) than low GBWT group (P=0.007). Conclusions: GBWT can be used to assess organ congestion in patients with HF.

背景：弥漫性胆囊（GB）壁增厚是由心力衰竭（HF）等全身静脉压升高引起的。本研究探讨了胆囊壁厚度（WT）与 HF 之间的关系，以及 GBWT 对预后的影响。方法和结果：这项前瞻性研究纳入了 116 名高血压患者和 11 名健康对照者。在这 116 名患者中，有 30 名患者在餐后状态下测量了胃壁厚度，或有胃壁疾病的病史和/或体征，但被排除在外。其余 86 名患者的 GBWT 值明显高于对照组（中位数[四分位数间距{IQR}] 分别为 2.0 [1.7-2.4] mm 与 1.3 [1.1-1.6] mm；PC 结论：GBWT可用于评估高血压患者的器官充血情况。

Launching Circulation Reports　― A New Era of Challenge in Cardiovascular Science ― 推出循环报告——心血管科学新时代的挑战

Circulation reports

Pub Date : 2019-03-01 DOI: 10.1253/circrep.CR-19-0006

Y. Yonemitsu

as difficulties in publishing papers, have caused this imbalance between clinical and basic cardiovascular sciences in our Journals, and particularly in scientific activity in Japan. The limitless publishing space of Circulation Reports and the seamless exchange of manuscripts with Circulation Journal will therefore help to increase your motivation for basic cardiovascular science. Also, this Editorial policy of course applies to cardiovascular scientists all over the world.

由于论文发表困难，导致了我们期刊中临床和基础心血管科学的不平衡，特别是在日本的科学活动中。《循环报告》的无限出版空间和与《循环期刊》的无缝手稿交换将有助于增加您对基础心血管科学的动力。同样，这一编辑政策当然适用于世界各地的心血管科学家。
