A 17-year-old female was transferred to our hospital due to high fever, general fatigue, and dim eyesight. Three weeks before, she had used cosmetic colored contact lenses and then suffered from bloodshot eyes associated with dim eyesight. Intermittent fever and general fatigue were followed by eye symptoms.

- The study aimed to assess the effects of starting sacubitril/valsartan (Sac/Val) therapy during hospitalization for acute heart failure (AHF) on NT-proBNP levels in Japanese patients.
- It involved a randomized trial with 400 patients, comparing those who switched to Sac/Val versus those who continued standard therapy, measuring changes in NT-proBNP at 4 and 8 weeks.
- Results showed that the Sac/Val group experienced significantly greater reductions in NT-proBNP levels, particularly in patients with lower left ventricular ejection fractions, with no significant safety concerns noted.
Background: This prospective multicenter study assessed the prevalence of myocardial injury in patients with COVID-19 using cardiac magnetic resonance imaging (CMR).
Methods And Results: We prospectively screened 505 patients with moderate to severe COVID-19 disease from 7 hospitals in Japan. Of these patients, 31 (mean [±SD] age 63.
Impact of Multidomain Frailty on the Mode of Death in Older Patients With Heart Failure: A Cohort Study.

Article Synopsis
- Frailty in elderly heart failure patients correlates with overall mortality, but specific causes of death remain underexplored, prompting further investigation into multidomain frailty's role.
- The study analyzed 1,181 hospitalized patients, finding that as frailty increased (measured across physical, social, and cognitive domains), so did the risk of death, particularly from noncardiovascular causes.
- Results indicated that patients with higher frailty scores (2 or 3 domains) had a significantly increased risk of noncardiovascular death, while the association was not as strong for heart failure or other cardiovascular deaths.
Patients with vasospastic angina (VSA) who are resuscitated from sudden cardiac arrest (SCA) are at a high risk of recurrent lethal arrhythmia and cardiovascular events. However, the benefit of the implantable cardioverter-defibrillator (ICD) therapy in this population has not been fully elucidated. The present study aimed to analyze the prognostic impact of ICD therapy on patients with VSA and SCA.

Surgical re-implantation of the right coronary artery to the aortic root to re-establish right coronary ostial circulation was successful. The patient resumed exercise and required no further medical therapy.

RCAos are associated with a high incidence of restenosis, and the implantations of drug-eluting stents for RCAos have not been fully elucidated. The study participants included 75 patients (72.
