Background: The Japanese Circulation Society survey revealed that Japanese female cardiologists exhibited a trend to refuse the chairperson position; however, the causal factors remain uncertain.Methods and Results: We distributed a questionnaire survey among chairpersons of the Chugoku regional meeting in November 2022. The rate of chair acceptance at the annual meeting tended to increase as the chairperson’s experience grew (first time chairing a meeting, 25.0%; 2–3 times, 33.3%; 4–5 times, 53.8%; ≥6 times, 70.0%; P=0.021).Conclusions: Providing inexperienced members with the chance to perform the role of chairperson will lead to them accepting to chair annual meetings.

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.

Background Normal values for echocardiographic measurements and the relationship between these parameters and age in a large Japanese population are still unknown. Methods and Results A total of 700 healthy Japanese aged 20-79 years underwent 2-dimensional and Doppler echocardiography at collaborating institutions. The respective mean values obtained in men and women were as follows: septal wall thickness, 0.9±0.1 and 0.8±0.1 cm; posterior wall thickness, 0.9±0.1 and 0.8±0.1 cm; left ventricular (LV) diastolic diameter, 4.8±0.4 and 4.4±0.3 cm; LV systolic diameter, 3.0±0.4 and 2.8±0.3 cm; LV diastolic volume, 93±20 and 74±17 ml; LV systolic volume, 33±20 and 25±7 ml; LV ejection fraction, 64±5 and 66±5%; maximum left atrial (LA) volume, 42±14 and 38±12 ml. Aortic root diameter, LV wall thickness, and LV mass slightly increased with age, whereas indexed LA volume did not vary with age. Diastolic parameters assessed by mitral inflow and mitral annular velocities declined with age, as previously reported. Conclusions Normal values of echocardiographic measurements in a large Japanese population are reported for the first time; several systolic and diastolic parameters varied with age. These results provide important reference values that should be useful in routine clinical practice as well as in clinical trials. (Circ J 2008; 72: 1859 - 1866)

Background: The purpose of the present study was to investigate gender differences in age-related changes of left ventricular (LV) and right ventricular (RV) geometries and functions throughout the entire adult age range using the Japanese Normal Values for Echocardiographic Measurements Project (JAMP) study database. Methods and Results: Seven hundred healthy volunteers (aged 20-79 years) underwent 2-dimensional and Doppler echocardiography. The subjects were stratified into 6 different age groups and then stratified by gender in each age group. LV diastolic function was assessed from pulsed wave Doppler measurements of mitral early (E) and late (A) inflow velocities and tissue Doppler measurements of mitral early (e') and late (a') annular velocities. LV volume decreased and LV mass increased with age to a similar extent in both men and women. Furthermore, for subjects <50 years, women had significantly greater E, E/A ratio and e' than men, but these parameters were similar between genders in subjects >50 years. In addition, there was a significant interaction between age and gender that affected the differences in E, e' and E/e' among the groups (P<0.03, P<0.01, and P<0.03, respectively; ANOVA). There were no gender differences in age-related changes in RV parameters. Conclusions: Gender differences were found in age-related changes in LV diastolic function in a healthy population. Gender differences should be considered for optimal diagnosis and management of cardiovascular disease. (Circ J 2011; 75: 2840-2846)
