Article Synopsis
- The study examined how outpatient oral loop diuretic dose changes affect the health outcomes of heart failure patients, following 679 individuals between 2015 and 2019.
- It categorized patients into three groups based on their diuretic dose: no reduction, single reduction, and successive reductions, finding that fewer deaths and heart failure hospitalizations were linked to dose reductions.
- Ultimately, the research concluded that reducing loop diuretic doses can be a sign of better prognosis for patients with heart failure.
Article Synopsis
- This study examined the relationship between heart failure (HF) and sarcopenia, focusing on the characteristics and prognosis of 256 patients diagnosed with both conditions between 2018 and 2021.
- Results showed that patients with reduced left ventricular ejection fraction (HFrEF) had a significantly worse prognosis, with fewer women and higher rates of ischemic heart disease compared to those with preserved ejection fraction (HFpEF).
- Key predictors of death in these patients were older age, higher NYHA class, elevated BNP levels, and reduced LVEF, highlighting the need for careful monitoring and treatment based on these factors.
Primary aldosteronism is often associated with heart failure (HF), and is reportedly difficult to treat in some cases. We report a case of severe HF associated with primary aldosteronism. A patient with HF, who was suspected of having primary aldosteronism, was referred to and examined at our hospital.

Methods And Results: CS patients who underwent BMIPP and FDG-PET within 2 months were enrolled. The recurrence-free group included patients with standardized uptake value (SUVmax) < 4 in the myocardium consecutively for ≥ 2 years.
Histopathological and genetic examinations were conducted on grayish-white solid hepatic nodules in 150 horses imported from Canada, in order to investigate larval infection. Ten of the 150 horses (6.7%) were diagnosed with alveolar hydatid disease.

Methods: We enrolled 15 patients with advanced-stage heart failure who underwent implantation of continuous-flow-LVAD.
Background: The prevalence and clinical features of the systolic anterior motion of the mitral valve (SAM) without hypertrophic cardiomyopathy (HCM) have not been studied well.
Methods: Records of 9180 sequential patients who underwent echocardiography at Tokyo Women's Medical University Hospital were reviewed. SAM patients were divided into those with HCM (HCM; n=60, 68%) and those without HCM (non-HCM; n=28, 32%).
