Background Cardiac rehabilitation (CR) is categorized as a Class I recommendation in guidelines for the management of patients with acute coronary syndrome (ACS); however, nationwide studies on CR in patients with ACS remain limited in Japan. Methods and Results The Japanese Association of Cardiac Rehabilitation (JACR) Registry is a nationwide, real-world database for patients participating in CR. From the JACR Registry database, we analyzed 924 patients participating in Phase II CR in 7 hospitals between September 2014 and December 2016. The mean age of patients was 65.9±12.0 years, and 80% were male. The prevalence of ST-elevation myocardial infarction (STEMI), non-STEMI (NSTEMI), and unstable angina pectoris (UAP) was 58%, 9%, and 33%, respectively. The prevalence of hypertension, diabetes, dyslipidemia, current smoking, and a family history was 55%, 27%, 67%, 21%, and 10%, respectively. Among the entire CR cohort at baseline, 96%, 78%, and 92% were treated with aspirin, β-blockers, and statins, respectively. After CR, the values of body mass index, the lipid profile, and exercise capacity significantly improved in the STEMI, NSTEMI and UAP groups. Conclusions In the JACR Registry, a high rate of guideline-recommended medications at baseline and improvements in both coronary risk factors and exercise capacity after CR were observed in patients with ACS.Background Atrial fibrillation (AF) ablation is associated with a good prognosis; nevertheless, the effect of post-procedural systolic function on a patient's prognosis remains uncertain. Methods and Results Of 1,077 consecutive patients undergoing AF ablation, the prognosis of 150 patients with abnormal left ventricular ejection fraction (LVEF; less then 50%) was evaluated. Patients were categorized as having reduced LVEF (rEF; LVEF less then 40%), mid-range ejection fraction (mrEF; 40%≤LVEF less then 50%), or preserved LVEF (pEF; LVEF ≥50%). see more Post-procedural LVEF, evaluated 3 months after the procedure, was post-rEF in 28 patients (19%), post-mrEF in 49 (33%), and post-pEF in 73 (49%). During the median follow-up of 31 months, the cumulative ratios of the composite outcome (heart failure hospitalization or death) in the post-rEF, post-mrEF, and post-pEF groups were 18%, 5%, and 2%, respectively, at 1 year and 50%, 13%, and 4%, respectively, at 3 years (P less then 0.0001). The post-rEF group had a 4.5- to 5.0-fold higher risk of the outcome compared with the post-pEF group, whereas the post-mrEF group showed no risk after adjusting for confounders, including age ≥65 years, preprocedural LVEF category, and recurrence of atrial tachyarrhythmia. Conclusions Patients with post-mrEF had a comparable prognosis to those with post-pEF over a relatively long follow-up, whereas those with post-rEF had the poorest outcome of the 3 groups, regardless of preprocedural LVEF status.Background The prevalence of obesity in Russia has increased sharply since the mid-1990s. Interestingly, the prevalence of obesity in Japan is lower than in many Western countries. Japan has implemented different types of weight control programs using a smart device to monitor patients remotely. New health promotion methods from Japan are now being used in Russia. The Russian-Japanese "Tackle Obesity and Metabolic Syndrome Outcome by Diet, Activities and Checking Body Weight Intervention" (RJ-TOMODACHI) study aims to evaluate a preventive intervention using Japanese health monitoring technology in reducing excess body weight, compared with standard care, in Russia. Methods and Results The trial is a single-center, 3-armed, parallel group randomized controlled trial conducted among overweight/obese adults. It has been designed to compare the effectiveness of 2 newly developed interventions against standard care for 6 months. Participants in the low- and high-intensity intervention groups will have 3 and 6 consultations over the study period, respectively. In all, 260 adults were screened at baseline; 65 did not participate in the trial for various reasons. The remaining 195 people were randomized into 3 groups (high-intensity intervention, n=73, low-intensity, n=73; standard care group, n=49). Conclusions The trial protocol has been designed so that the methodology can be adapted for use in Russia.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 Drug-coated balloon strategies in endovascular therapy often result in severe dissection, so lesion preparation must be improved. We evaluated the efficacy of a gradual inflation method, termed "super slow inflation" (SSI), in preparing lesions to avoid severe dissections. Methods and Results The association between balloon pressure and the dilatation of a model constricted vessel, as well as the load applied to the balloon surface, were determined using a burst leak detector for a quick inflation (QI; 1 atm/s) protocol and SSI (1 atm/20 s). A retrospective, single-center, non-randomized study evaluated differences in vessel dissection patterns after balloon angioplasty depending on inflation method in 81 consecutive patients (mean [±SD] age 74.6±9.2 years; 54 males) who underwent balloon angioplasty for de novo femoropopliteal lesions between January 2017 and March 2019. In the constricted vessel model, vessel dilatation increased gradually using SSI, with the maximum dilatation load being approximately 100 g lower for the SSI than QI protocol.
