Background:Patient perspectives in cardiovascular diseases (CVD) are significantly associated with clinical outcomes.Methods and Results:Among 100 patients who responded to a telephone survey in a university hospital setting in Tokyo during the coronavirus disease (COVID-19) pandemic, 20% reported depressive symptoms and 33% were hesitant to contact medical staff in the event of CVD exacerbation. Interestingly, the frequency of depressive symptoms was maintained even after a decline in the number of newly COVID-19-infected patients.Conclusions:Our telemedicine practices revealed the magnitude of our patients’ mental health conditions and their hesitation to contact medical facilities in the event of CVD exacerbation.

Background:Hydrogen gas inhalation (HI) reduced infarct size and mitigated adverse left ventricular (LV) remodeling in a rat model of acute myocardial infarction (AMI). We designed a prospective, open-label, rater-blinded clinical pilot study in patients experiencing ST-elevated MI (STEMI).Methods and Results:The 20 patients with an initial diagnosis of STEMI were assigned to either an HI group (1.3% H2with 26% oxygen) or a control group (26% oxygen). There were no HI-related severe adverse events. In the full analysis set, the cardiac salvage index as evaluated using cardiac magnetic resonance imaging at 7 days after primary percutaneous coronary intervention (PCI), showed no significant between-group difference (HI: 50.0±24.3%; control: 60.1±20.1%; P=0.43). However, the improvement from day 7 in the HI group was numerically greater than that in the control group in some of the surrogate outcomes at 6-month follow-up, including the LV stroke volume index (HI: 9.2±7.1 mL/m2; control: −1.4±7.2 mL/m2; P=0.03) and the LV ejection fraction (HI: 11.0%±9.3%; control: 1.7%±8.3%; P=0.11).Conclusions:The first clinical study has shown that HI during PCI is feasible and safe and may also promote LV reverse remodeling at 6 months after STEMI. The study was not powered to test efficacy and a further large-scale trial is warranted. (Clinical trials registration: UMIN00006825)

A 45-year-old male was admitted to our hospital after successful resuscitation of cardiac arrest. Ventricular fibrillation (VF) had occurred during breakfast and was defibrillated by an automated external defibrillator operated by emergency medical service staff. On admission, his ECG demonstrated complete right bundle branch block as the sole abnormality. Intensive examination could not detect any structural disease leading to a diagnosis of idiopathic VF and implantation of an ICD. VF storm occurred one month after hospital discharge and beta-blocker, amiodarone, and sedative administration had no effect on VF. Likewise, catheter ablation for triggering premature ventricular beats failed to control the VF storm. The VF storm then subsided in the following weeks and the patient was discharged on amiodarone. A half month later VF storm recurred and the patient was admitted again. This time, isoproterenol infusion was effective in suppressing VF, and thereafter the patient was administered bepridil and followed up without recurrence of VF for 1.5 years. From these beneficial effects, the VF of the patient was suggested to share common arrhythmogenic characteristics to those of Brugada syndrome or J-wave associated VF.
