Background:The impact of promotional tweets from the official journal account (forCirculation JournalandCirculation Reports) on article viewership has not been thoroughly evaluated.Methods and Results:We retrospectively collected journal viewership data forCirculation JournalandCirculation Reportsfrom March 2021 to August 2021. We compared viewership between articles with (n=15) and without (n=250) tweets. After 1 : 4 propensity score matching (15 tweeted articles and 60 non-tweeted matched controls), journal viewership metrics within 7 days of the tweeting date (and the hypothetical tweeting date), was larger in tweeted articles than non-tweeted articles (median [interquartile range] Abstract page views 89 [60–104] vs. 18 [8–41]).Conclusions:This pilot study suggests a positive relationship between journal-posted promotional tweets and article viewership.

Background:Twitter has become increasingly popular at annual medical congresses as a platform to communicate to attendees. In contrast, Twitter is not as frequently used in Japan as compared with other countries. Herein, we reviewed the literature and discuss the potential role and risks of “tweet the meeting” in Japan.Methods and Results:We performed a literature review to consider the recent trend of tweeting the meeting, including benefits and how to tweet, as well as potential risks. Upon officially deciding to tweet the meeting, a number of societies and professional organizations developed strategies to enhance the attendees’ experience using multiple modalities and guides. Although there are several risks, we provide a concise guide to tweeting the meeting for the Japanese audience, which could be useful for understanding what should be done before and during a conference.Conclusions:The use of Twitter at medical congresses has many possibilities, and there are numerous potentials in many areas. We should discuss this in the light of the benefits for congress attendees in Japan.

Background:Twitter has become increasingly popular at annual medical congresses as a platform to communicate to attendees. The aim of this study is to reveal the twitter usage in the annual congress of the Japanese Cirsulation Society.Methods and Results:We compared the total number of tweets during the Japanese Circulation Society’s annual meetings in 2019 and 2020. The total number of tweets increased from 7,587 in 2019 to 23,867 in 2020. Most tweets were retweets (>70%), and approximately half of Twitter users tweeted only once.Conclusions:Twitter usage during the Japanese Circulation Society’s annual meeting increased from 2019 to 2020, and a large number of tweets were from Twitter ambassadors of the Japanese Circulation Society. However, further evaluation is needed, with future studies investigating the usefulness of this platform.

Background:Despite the rapidly increasing attention being given to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection, more commonly known as coronavirus disease 2019 (COVID-19), the relationship between cardiovascular disease and COVID-19 has not been fully described.Methods and Results:A systematic review was undertaken to summarize the important aspects of COVID-19 for cardiologists. Protection both for patients and healthcare providers, indication for treatments, collaboration with other departments and hospitals, and regular update of information are essentials to front COVID-19 patients.Conclusions:Because the chief manifestations of COVID-19 infection are respiratory and acute respiratory distress syndrome, cardiologists do not see infected patients directly. Cardiologists need to be better prepared regarding standard disinfection procedures, and be aware of the indications for extracorporeal membrane oxygenation and its use in the critical care setting.

Background: During the COVID-19 pandemic, cardiovascular hospitalizations decreased and in-hospital mortality for ST-elevation myocardial infarction and heart failure increased. However, limited research has been conducted on hospitalization and mortality rates for cardiovascular disease (CVD) other than ischemic heart disease and heart failure.Methods and Results: We analyzed the records of 530 certified hospitals affiliated with the Japanese Circulation Society obtained from the nationwide JROAD-DPC database between April 2014 and March 2021. A quasi-Poisson regression model was used to predict the counterfactual number of hospitalizations for CVD treatment, assuming there was no pandemic. The observed number of inpatients compared with the predicted number in 2020 was 88.1% for acute CVD, 78% for surgeries or procedures, 77.2% for catheter ablation, and 68.5% for left ventricular assist devices. Furthermore, there was no significant change in in-hospital mortality, and the decrease in hospitalizations for catheter ablation and valvular heart disease constituted 47.6% of the total decrease in annual hospitalization costs during the COVID-19 pandemic.Conclusions: Cardiovascular hospitalizations decreased by more than 10% in 2020, and the number of patients scheduled for left ventricular assist device implantation decreased by over 30%. In addition, in response to the COVID-19 pandemic, annual cardiovascular hospitalization costs were reduced, largely attributed to decreased catheter ablation and valvular heart disease.

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: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: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 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: Although reductions in hospitalizations for myocardial infarction and heart failure have been reported during the period of COVID-19 pandemic restrictions, it is unclear how the overall number of hospitalizations for cardiovascular disease (CVD) treatment changed in the early stages of the pandemic.Methods and Results: We analyzed the records of 574 certified hospitals affiliated with the Japanese Circulation Society and retrieved data from April 2015 to March 2020. Records were obtained from the nationwide Japanese Registry of All Cardiac and Vascular Diseases–Diagnosis Procedure Combination database. A quasi-Poisson regression model was used to estimate the number of hospitalizations for CVD treatment. Between January and March 2020, when the number of COVID-19 cases was relatively low in Japan, the actual/estimated number of hospitalizations for acute CVD was 18,233/21,634 (84.3%), whereas the actual/estimated number of scheduled hospitalizations was 16,921/19,066 (88.7%). The number of hospitalizations for acute heart failure and scheduled hospitalizations for valvular disease and aortic aneurysm were 81.1%, 84.6%, and 83.8% of the estimated values, respectively. A subanalysis that considered only facilities without hospitalization restrictions did not alter the results for these diseases.Conclusions: The spread of COVID-19 was associated with a decreased number of hospitalizations for CVD in Japan, even in the early stages of the pandemic.
