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. 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:The relationship between Twitter ambassadors and retweets has not been fully evaluated for “tweet the meeting” activity.Methods and Results:We collected data on the number of tweets and retweets during the Japanese Circulation Society’s (JCS) annual meetings in 2019, 2020, and 2021. After adjustment, JCS Twitter Ambassadors, selected by the JCS to increase the meeting’s visibility, increased the total number of retweets by 9%.Conclusions:This is the first report on the numerical relationship between JCS Twitter Ambassadors and the total number of retweets during an annual congress. Original tweets by JCS Twitter Ambassadors increased the number of retweets, but retweets by influencers were more effective at stimulating social media engagement.

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: 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.

Background:The aim of this study was to assess the echocardiographic characteristics of chronic hemodialysis (HD) patients with end-stage renal disease (ESRD) in a multicenter prospective cohort study.Methods and Results:Three hundred and fifteen patients with ESRD (67.9±10.6 years, 47.6% male) on chronic HD for ≥1 year were examined on transthoracic echocardiography, including Doppler-derived aortic valve area (AVA) measurement. Only 11.5% and 3.4% of all patients had normal left ventricular (LV) geometry and normal LV filling pattern, respectively. The majority of patients had aortic and mitral valvular calcification, and approximately 50% of all 315 patients had aortic valve narrowing with AVA <2.0 cm2. Patients were divided into 3 groups according to AVA index tertile: group 1, highest tertile; group 2, middle tertile; and group 3, lowest tertile. Group 3 was older, had a greater cardiothoracic ratio on chest X-ray, higher plasma brain natriuretic peptide and total LV afterload, and lower stroke volume index than the other 2 groups. Age and intact parathyroid hormone (PTH) level were independently associated with low AVA index.Conclusions:Patients with ESRD on chronic HD have a high prevalence of cardiac structural and functional abnormalities including calcified aortic sclerosis. High age and PTH were associated with aortic valve narrowing in these patients.

Background:Secondary hyperparathyroidism develops as a compensatory response to chronic heart failure (HF) and renal failure. The role of parathyroid hormone (PTH) level in acute decompensated HF remains unclear. The aim of this study was therefore to investigate the relationships among mortality, renal function, and serum PTH level in acute decompensated HF patients.Methods and Results:A total of 266 consecutive patients admitted for acute decompensated HF without acute coronary syndrome (78±12 years; 48% male) were enrolled. Demographic, clinical, and laboratory characteristics were obtained on admission.During 1-year follow-up, 65 patients (24%) died. Serum PTH level on admission was within the normal range (10–65 pg/ml) in 108 patients (41%), of whom 39 (15%) had low-normal PTH (10–40 pg/ml). On Kaplan-Meier analysis all-cause mortality was significantly higher in patients with low-normal PTH than in those with high-normal (40–65 pg/ml) or high (>65 pg/ml) PTH (log-rank test). On univariate and multivariate Cox regression analysis, low-normal PTH was significantly associated with increased all-cause mortality (unadjusted HR, 2.88; 95% CI: 1.69–4.91; P<0.001; adjusted HR, 3.84; 95% CI: 1.54–9.57; P=0.004).Conclusions:In patients with acute decompensated HF resulting in hospitalization, low-normal PTH on admission is associated with increased all-cause mortality, regardless of renal function.
