Due to the COVID-19 pandemic, the 84thAnnual Meeting of the Japanese Circulation Society (JCS) was held in a web-based format for the first time in its history as “The Week for JCS 2020” from Monday, July 27 to Sunday, August 2, 2020. All sessions, including general abstracts, were streamed live or on-demand. The main theme of the meeting was “Change Practice!” and the aim was to organize the latest findings in the field of cardiovascular medicine and discuss how to change practice. The total number of registered attendees was over 16,800, far exceeding our expectations, and many of the sessions were viewed by far more people than at conventional face-to-face scientific meetings. At this conference, the power of online information dissemination was fully demonstrated, and the evolution of online academic meetings will be a direction that cannot be reversed in the future. The meeting was completed with great success, and we express our heartfelt gratitude to all affiliates for their enormous amount of work, cooperation, and support.

Background:The effect of diabetes mellitus (DM) status on the long-term risk for heart failure (HF) in patients undergoing coronary revascularization has not been adequately evaluated.Methods and Results:In this study, 15,231 patients who underwent coronary revascularization in the CREDO-Kyoto Registry Cohort-2 were divided into 2 groups according to DM status (DM group: n=5,999; Non-DM group: n=9,232). The DM group was further divided into 2 groups according to insulin treatment (insulin-treated DM [ITDM]: n=1,353; non-insulin-treated DM [NITDM]: n=4,646). The primary outcome measure was HF hospitalization. The cumulative 5-year incidence of HF hospitalization was significantly higher in the DM than non-DM group (11.0% vs. 6.6%, respectively; log-rank P<0.0001), and in the ITDM than NITDM group (14.6% vs. 10.0%, respectively; log-rank P<0.0001). After adjusting for confounders, the increased risk of HF hospitalization with DM relative to non-DM remained significant (hazard ratio [HR] 1.47, 95% confidence interval [CI] 1.30–1.67, P<0.0001), whereas the risk associated with ITDM relative to NITDM was not significant (HR 1.17, 95% CI 0.96–1.43, P=0.12).Conclusions:The adjusted long-term risk for HF hospitalization after coronary revascularization was significantly higher in DM than non-DM patients, regardless of revascularization strategy, but did not differ between ITDM and NITDM patients.

Aim: Dual antiplatelet therapy (DAPT) with aspirin and clopidogrel is essential after percutaneous coronary intervention (PCI). Clopidogrel is a prodrug and changed into active metabolite by cytochrome p450 enzymes (CYPs), especially CYP2C19. Proton pump inhibitors (PPIs) are used for the prevention of aspirin-induced gastrointestinal bleeding. PPIs are also metabolized by CYP2C19, although the degree of its contribution is dependent on the kind of PPI. Omeprazole, a PPI, has been reported to weaken the antiplatelet effects of clopidogrel. Famotidine, a histamine receptor type 2 (H2) blocker, could also be an alternative to PPIs. The aim of this study was to evaluate the effects of PPIs and an H2 blocker on the antiplatelet function of clopidogrel.Methods: Patients receiving DAPT due to prior PCI, who took either omeprazole or rabeprazole, were enrolled (n=25). The initial PPI was changed to the other PPI as a crossover study. In another study, patients undergoing DAPT without taking PPIs or H2 blockers were enrolled (n=30) and famotidine was added.Results: Platelet aggregability when taking omeprazole was higher than when taking rabeprazole, evaluated by an optical aggregometer using collagen as a stimulus (p=0.0051) and by the VerifyNow P2Y12 assay (p=0.0060). Platelet aggregability when taking rabeprazole was comparable to that in control patients (n=15). Concomitant use of famotidine had no effect.Conclusion: Omeprazole significantly reduced the antiplatelet effect of clopidogrel and this effect on clopidogrel was stronger than that of rabeprazole. Concomitant use of famotidine had no effect on the antiplatelet effect of clopidogrel.
