Background:It is commonly believed that a full moon affects human behavior or the occurrence and outcome of various diseases; thus, the occurrence of out-of-hospital cardiac arrest (OHCA) might increase during full moon nights.Methods and Results:This nationwide, population-based observational study consecutively enrolled OHCA patients in Japan with attempted resuscitation between 2005 and 2016. The primary outcome measure was the occurrence of OHCA. Based on the double-control method, assuming Poisson sampling, we evaluated the average number of OHCA events that occurred on full moon nights compared with that which occurred on control nights, which included events that occurred on the same calendar days 1 week before and after the full moon nights. A total of 29,552 OHCA that occurred on 148 full moon nights and 58,707 OHCA that occurred on 296 control nights were eligible for analysis. The occurrence of OHCA did not differ between full moon and control nights (199.7 vs. 198.3 per night; relative risk [RR], 1.007; 95% CI: 0.993–1.021). On subgroup analysis, compared with control nights, the RR of OHCA occurrence were 1.013 (95% CI: 0.994–1.032, P=0.166) and 0.998 (95% CI: 0.977–1.020, P=0.866) for cardiac and non-cardiac origins, respectively.Conclusions:In this population, there was no significant difference in OHCA occurrence between full moon and control nights.

Background: Transcatheter aortic valve (TAV)-in-TAV is an attractive treatment for degenerated TAV. The risk of coronary artery occlusion due to sequestration of the sinus of Valsalva (SOV) in TAV-in-TAV has been reported, but the risk in Japanese patients is unknown. This study aimed to investigate the proportion of Japanese patients who are expected to experience difficulty with the second TAV implantation (TAVI) and evaluate the possibility of reducing the risk of coronary artery occlusion.Methods and Results: Patients (n=308) with an implanted SAPIEN 3 were divided into 2 groups: a high-risk group, which included patients with a TAV–sinotubular junction (STJ) distance <2 mm and a risk plane above the STJ (n=121); and a low-risk group, which included all other patients (n=187). The preoperative SOV diameter, mean STJ diameter, and STJ height were significantly larger in the low-risk group (P<0.05). The cut-off value for predicting the risk of SOV sequestration due to TAV-in-TAV in the difference between the mean STJ diameter and area-derived annulus diameter was 3.0 mm (sensitivity 70%; specificity 68%; area under the curve 0.74).Conclusions: Japanese patients may have a higher risk for sinus sequestration caused by TAV-in-TAV. The risk of sinus sequestration should be assessed before the first TAVI in young patients who are likely to require TAV-in-TAV, and whether TAVI is the best aortic valve therapy must be carefully decided.

Background: Previous research has investigated the effectiveness of the “Tweet the Meeting” campaign, but the relationship between tweet content and the number of retweets has not been fully evaluated.Methods and Results: We analyzed the number of tweets and retweets during the Japanese Circulation Society’s 2022 annual meeting. The ambassador group had significantly more session- and symposium-related tweets than the non-ambassador group (P<0.001), associated with the nubmer of retweets. Symposium-related tweets with figures generated more retweets than those without figures (mean [±SD] 3.47±3.31 vs. 2.48±1.94 retweets per tweet, respectively; P=0.001).Conclusions: The study revealed that official meeting-designated Twitter ambassadors disseminate more educational content than non-ambassadors, and generated more retweets.

Background:Atrial fibrillation (AF) and mitral regurgitation (MR) are frequently combined in patients with heart failure (HF). However, the effect of AF on the prognosis of patients with HF and MR remains unknown.Methods and Results:We studied 867 patients (mean age 73 years; 42.7% female) with acute decompensated HF (ADHF) in the NARA-HF registry. Patients were divided into 4 groups based on the presence or absence of AF and MR at discharge. Patients with severe MR were excluded. The primary endpoint was the composite of cardiovascular (CV) death and HF-related readmission. During the median follow-up of 621 days, 398 patients (45.9%) reached the primary endpoint. In patients with MR, AF was associated with a higher incidence of the primary endpoint regardless of left ventricular function; however, in patients without MR, AF was not associated with CV events. Cox multivariate analyses showed that the incidence of CV events was significantly higher in patients with AF and MR than in patients with MR but without AF (hazard ratio 1.381, P=0.036). Similar findings were obtained in subgroup analysis of patients with AF and only mild MR.Conclusions:The present study demonstrated that AF is associated with poor prognosis in patients with ADHF with mild to moderate MR, but not in those without MR.

Background:Cardiovascular department restriction policies on procedures resulting from the COVID-19 pandemic have not been fully evaluated.Methods and Results:We performed a retrospective analysis of a nationwide survey performed by the Japanese Circulation Society in August 2020. The total response rate was 48.9% (651/1,331). The rate of restriction of cardiovascular procedures peaked in April. Exacerbations of heart failure due to hospital restrictions were noted in 43.8% of departments.Conclusions:Many departments restricted their cardiological procedures, and this rate changed according to the pandemic situation. The exacerbation of cardiovascular disease resulting from pandemic restrictions should not be ignored.

Background:From the early phase of the Coronavirus disease-2019 (COVID-19) pandemic, cardiologists have paid attention not only to COVID-19-associated cardiovascular sequelae, but also to treatment strategies for rescheduling non-urgent procedures. The chief objective of this study was to explore confirmed COVID-19 cardiology case experiences and departmental policies, and their regional heterogeneity in Japan.Methods and Results:We performed a retrospective analysis of a nationwide survey performed by the Japanese Circulation Society on April 13, 2020. The questionnaire included cardiology department experience with confirmed COVID-19 cases and restriction policies, and was sent to 1,360 certified cardiology training hospitals. Descriptive analysis and spatial autocorrelation analysis of each response were performed to reveal the heterogeneity of departmental policies. The response rate was 56.8% (773 replies). Only 16% of all responding hospitals experienced a COVID-19 cardiology case. High-risk procedures were restricted in more than one-fifth of hospitals, including transesophageal echocardiography (34.9%) and scheduled catheterization (39.5%). The presence of a cardiologist in the COVID-19 team, the number of board-certified cardiologists, any medical resource shortage and a state of emergency were positively correlated with any type of restriction.Conclusions:We found both low clinical case experiences with COVID-19 and restrictions of cardiovascular procedures during the first COVID-19 wave in Japan. Restrictions arising as a result of COVID-19 were affected by hospital- and country-level variables, such as a state of emergency.

Background: Although accurate assessment of right ventricular (RV) morphology and function is clinically important, data regarding reference values for echocardiographic measurements of the right ventricle in the Japanese population are limited.Methods and Results: The World Alliance Society of Echocardiography (WASE) Normal Values Study was conducted to examine normal echocardiographic values in 15 countries. Using the WASE study database, we analyzed 2-dimensional echocardiographic parameters of RV size and systolic function in 192 healthy Japanese individuals and compared them with those obtained from 153 healthy American individuals. In the Japanese population, the absolute values of RV dimensions were smaller for women than men, although the difference disappeared after the data were adjusted for body surface area. RV dimensions, RV length and RV area were smaller in the elderly, but age did not affect RV systolic function. The absolute value, but not the adjusted value, of RV size tended to be smaller in Japanese than American individuals for both sexes. For men, RV systolic function parameters were lower in the Japanese population. This trend was not seen in women.Conclusions: The present study identified normal reference values for RV size and systolic function in a healthy Japanese population. Sex, age, and race had a significant impact on RV size; however, this trend was weak for RV systolic function.

Background: Trastuzumab, an anti-human epidermal growth factor receptor 2 (HER2) monoclonal antibody, is a specific first-line treatment for patients with HER2-positive cancers. Cardiac dysfunction is among the most problematic adverse events associated with trastuzumab. Although regular echocardiographic screening is recommended for early detection of cardiac damage, few reports have investigated the validity of echocardiographic screening in chemotherapy. Therefore, the aim of this study was to determine whether a GLS-guided management approach could reduce cardiotoxicity and discontinuation of trastuzumab chemotherapy.Methods and Results: To evaluate the usefulness of global longitudinal strain (GLS)-guided cardioprotective interventions, we retrospectively analyzed 67 patients treated with trastuzumab who underwent structured echocardiographic assessments before and after 1, 3, and 6 courses of trastuzumab administration. If a >15% relative decrease in GLS was identified, cardioprotective agents were administered. Thirty (44.8%) patients had breast cancer; the remaining patients had salivary gland cancer. The median observation period for the intervention group was 304 days from the initial evaluation. Nineteen (28.4%) patients exhibited a >15% relative decrease in GLS, and consequently received cardioprotective agents. The incidence of trastuzumab discontinuation for cardiogenic reasons was significantly lower among patients receiving GLS-guided interventions than among those not receiving the intervention (2.4% vs. 24.0%; P=0.009). The incidence of a subsequent decline in left ventricular ejection fraction was lower among patients receiving the intervention than among those not receiving the intervention (4.8% vs. 24.0%; P=0.04).Conclusions: GLS-guided cardioprotective intervention significantly decreased the incidence of trastuzumab discontinuation.

Background:Various issues, such as gender diversity and overwork, need to be considered in cardiovascular workplaces. Here, we report the results of 2 questionnaire surveys conducted among members of the Chugoku branch of the Japanese Circulation Society.Methods and Results:The first questionnaire was posted to all 194 female members in 2018. Of the 73 respondents, 61.6% reported feeling that it would be difficult to continue in cardiovascular care. The second questionnaire was completed by participants of the Chugoku Regional Meeting in 2019. Of the 133 respondents, 42.4% reported difficulties continuing in cardiovascular care. Respondents reporting difficulties had a significantly lower mean age, a higher frequency of day and night shifts, and a higher rate of working >80 h/week than respondents who did not report such difficulties. In logistic regression analysis, working >80 h/week was the only independent factor associated with difficulties continuing in cardiovascular care (odds ratio 4.16; 95% confidence interval 1.46–11.9; P=0.008). Although 47.4% of respondents worked >960 h overtime per year (considered a risk factor for death from overwork), 59.6% of these respondents reported being satisfied with their current situation.Conclusions:In the Chugoku region, the work-life balance of medical personnel engaged in cardiovascular care has not been sufficiently secured. In order to promote diverse human resources, we need to recognize the current situation and continue to take countermeasures.

Background: The purpose of this study was to investigate the actual conditions of cardiac rehabilitation (CR) for elderly patients with heart failure (HF) in outpatient rehabilitation (OR) facilities using long-term care insurance systems.Methods and Results: This was a cross-sectional web-based questionnaire survey conducted at 1,258 facilities in the Kansai region (6 prefectures) of Japan from October to December 2021. In all, 184 facilities responded to the web-based questionnaire (response rate 14.8%). Of these facilities, 159 (86.4%) accepted patients with HF. Among the patients with HF, 94.3% were aged ≥75 years and 66.7% were classified as New York Heart Association functional class I/II. Facilities treating patients with HF generally provided exercise therapy, patient education, and disease management, which were components of CR. Many facilities not currently treating patients with HF responded positively stating they will accept HF patients in the future. However, a few facilities responded by stating that they are waiting for clearer evidence demonstrating the beneficial effect of OR on patients with HF.Conclusions: The present results show the possibility that outpatient CR can be performed for elderly patients with HF in other than medical insurance.

Background: Physiological assessments using fractional flow reserve (FFR) and resting full-cycle ratio (RFR) have been recommended for revascularization decision making. Previous studies have shown a 20% rate of discordance between FFR and RFR. In this context, the correlation between RFR and FFR in patients with renal dysfunction remains unclear. This study examined correlations between RFR and FFR according to renal function.Methods and Results: In all, 263 consecutive patients with 370 intermediate lesions were enrolled in the study. Patients were classified into 3 groups according to renal function: Group 1, estimated glomerular filtration rate (eGFR) ≥60 mL/min/1.73 m2; Group 2, 30 mL/min/1.73 m2≤eGFR<60 mL/min/1.73 m2; Group 3, eGFR <30 mL/min/1.73 m2. The discordance between FFR and RFR was assessed using known cut-off values for FFR (≤0.80) and RFR (≤0.89). Of the 370 lesions, functional significance with FFR was observed in 154 (41.6%). RFR was significantly correlated with FFR in all groups (Group 1, R2=0.62 [P<0.001]; Group 2, R2=0.67 [P<0.001]; Group 3, R2=0.46 [P<0.001]). The rate of discordance between RFR and FFR differed significantly among the 3 groups (Group 1, 18.8%; Group 2, 18.5%; Group 3, 42.9%; P=0.02).Conclusions: The diagnostic performance of RFR differed based on renal function. A better understanding of the clinical factors contributing to FFR/RFR discordance, such as renal function, may facilitate the use of these indices.

Background: In patients with aortic stenosis (AS), measurement of aortic valve calcification (AVC) using computed tomography (CT) is recommended in cases where echocardiographic measurements are inconclusive. However, sex-specific AVC thresholds proposed in the guidelines for predicting severe AS (women: 1,200 arbitrary units [AU]; men: 2,000 AU) are based on studies from Western countries.Methods and Results: We retrospectively included 512 Japanese patients with at least moderate AS who underwent transthoracic echocardiography and CT. AVC was quantified using the Agatston method. AVC was positively correlated with peak aortic jet velocity and mean transvalvular gradient (mPG), and negatively correlated with aortic valve area (AVA) and the AVA index (AVAi). In 257 patients with concordant AS grading (152 severe AS [AVAi ≤0.6 cm2/m2, mPG ≥40 mmHg], 105 moderate AS [AVAi >0.6 cm2/m2, mPG <40 mmHg]), receiver operating characteristic curve analysis of AVC predicting severe AS yielded an area under the curve of 0.91 (95% confidence interval [CI] 0.87–0.95; P<0.001) in women and 0.86 (95% CI 0.75–0.98; P<0.001) in men. The optimal thresholds (women: 1,379 AU; men: 1,802 AU) were close to those proposed in the guidelines. The diagnostic accuracy of the thresholds in the guidelines was similar to that of the optimal thresholds.Conclusions: The sex-specific AVC thresholds proposed in international guidelines can be applied to Japanese AS patients, yielding similar diagnostic accuracy as the optimal cut-off derived from the study patients.

Background:Demand is growing for remote electrocardiogram (ECG) monitoring systems in the COVID-19 era in Japan. This study describes initial experiences with a small wireless ECG monitoring device and the utility of delivery via the postal service for outpatient care in Japan.Methods and Results:Long-term ECG monitoring following postal delivery of the small ECG device was evaluated in 25 patients. The patients had no difficulties with either the postal delivery or self-fitting and wearing the devices. A median of 57 h monitoring per patient was performed. Arrhythmic events were detected in 8 patients. Most patients were satisfied with both the ECG devices and postal delivery.Conclusions:Postal delivery of ECG devices could be used in clinical practice to achieve less or no in-person contact during the COVID-19 era.

Background:Hypertension in patients with atrial fibrillation (AF) is a known independent risk factor for stroke. The Complete blood pressure (BP) monitor (Omron Healthcare, Kyoto, Japan) was developed as the first BP monitor with electrocardiogram (ECG) capability in a single device to simultaneously monitor ECG and BP readings. This study investigated whether the Complete can accurately differentiate sinus rhythm (SR) from AF during BP measurement.Methods and Results:Fifty-six consecutive patients with persistent AF admitted for catheter ablation were enrolled in the study (mean age 65.8 years; 83.9% male). In all patients, 12-lead ECGs and simultaneous Complete recordings were acquired before and after ablation. The Complete interpretations were compared with physician-reviewed ECGs, whereas Complete recordings were reviewed by cardiologists in a blinded manner and compared with ECG interpretations. Sensitivity, specificity, and κ coefficient were also determined. In all, 164 Complete and ECG recordings were simultaneously acquired from the 56 patients. After excluding unclassified recordings, the Complete automated algorithm performed well, with 100% sensitivity, 86% specificity, and a κ coefficient of 0.87 compared with physician-interpreted ECGs. Physician-interpreted Complete recordings performed well, with 99% sensitivity, 85% specificity, and a κ coefficient of 0.85 compared with physician-interpreted ECGs.Conclusions:The Complete, which combines BP and ECG monitoring, can accurately differentiate SR from AF during BP measurement.
