Background: Guideline-directed medical therapy has become an important component of heart failure (HF) therapy, with sacubitril/valsartan as one of the recommended drugs; however, the real-world prognostic implications of sacubitril/valsartan uptitration are unclear.

Methods And Results: Patients with HF newly initiated on sacubitril/valsartan were registered in a retrospective multicenter study (REVIEW-HF). In all, 995 patients were divided into 3 groups according to the maximum dose achieved: high dose, sacubitril/valsartan 400 mg; intermediate dose, sacubitril/valsartan 200-<400 mg; and low dose, sacubitril/valsartan <200 mg.

Background: Patients with heart failure exhibiting low systolic blood pressure (SBP) have a poor prognosis. Sacubitril/valsartan reduces cardiovascular events; however, its use in patients with low SBP has not been fully examined. Therefore, in this study, we aimed to investigate the association between baseline SBP and adverse events (AEs) in patients starting sacubitril/valsartan therapy using data from a real-world registry in Japan.

Article Synopsis
  • - The study focuses on the increasing detection of wild-type transthyretin (ATTR) amyloidosis and evaluates the effectiveness of Tc-labeled pyrophosphate (Tc-PYP) scintigraphy for diagnosing ATTR cardiac amyloidosis in patients across Japan from 2018 to 2022.
  • - Out of 180 patients, 135 were analyzed, with 62 testing positive for Tc-PYP; researchers developed a scoring system based on five clinical factors to predict positivity, revealing that a higher score correlates with a greater likelihood of positive results.
  • - The study concludes that combining commonly available clinical data can significantly enhance the pretest prediction accuracy for Tc-PYP scintigraphy, aiding clinicians in the early diagnosis of ATTR amyloidosis

Article Synopsis
  • Stage B heart failure (HF) involves structural heart disease without symptoms, and identifying risk in these patients is complex but crucial for early intervention.
  • A study of 1,646 heart failure patients established a scoring system called BEEAF to categorize stage B HF patients into low, moderate, and high-risk groups based on specific health indicators.
  • The results indicated that higher risk levels predicted worse outcomes, with high-risk stage B patients faring similarly to those in stage C HF.

Article Synopsis
  • A multicenter study in Japan assessed the safety and outcomes of patients with heart failure prescribed sacubitril/valsartan, revealing that many patients treated are not typically included in clinical trials.
  • Among 993 patients, significant adverse events (AEs) were noted in 22.5% within three months, with hypotension being the most common reason for discontinuation of the medication.
  • High-risk factors for experiencing AEs were identified, including worse heart failure symptoms and lower blood pressure or kidney function, highlighting the need for careful monitoring by healthcare providers.

Aims: The popularity of B-line-guided congestion assessment by lung ultrasound (LUS) has been increasing. However, the ability of novice residents to detect residual congestion with B-line-guided assessment by LUS after decongestion treatment is poorly understood. In this study, we investigated whether novice residents (no prior echocardiography experience) can acquire the skills for B-line-guided residual congestion assessment and whether the range of variation in assessment is acceptable in actual clinical use.

Introduction: Cardiac rehabilitation (CR) is strongly recommended as a medical treatment to improve the prognosis and quality of life of patients with heart failure (HF); however, participation rates in CR are low compared with other evidence-based treatments. One reason for this is the geographical distance between patients' homes and hospitals. To address this issue, we developed an integrated telerehabilitation platform, RH-01, for home-based CR.

Aims: Increased left atrial pressure leads to pulmonary congestion. Although the B-lines in lung ultrasound (LUS) are useful in detecting pulmonary congestion, data regarding the association between B-lines and invasive haemodynamics are inconsistent. This study aimed to explore the correlation of the B-line count by LUS with pulmonary capillary wedge pressure (PCWP) stratified for preserved and reduced ejection fraction (EF) in acute heart failure patients.

Objective Previous studies have described several prognostic factors for heart failure (HF); however, these results were derived from registries consisting of conventional age groups, which might not represent the increasingly aging society. The present study explored the prognostic factors for all-cause death in hospitalized patients with HF across different age categories using an acute HF registry that included relatively old patients. Methods From a total of 1,971 consecutive patients with HF, 1,136 patients were enrolled.

Aims: Acute decompensated heart failure (ADHF) is a frequent cause of hospitalization for patients with heart disease, and ADHF patients are at high risk of heart failure (HF) re-hospitalization. Residual congestion at discharge is also a strong predictor of poor outcomes and re-hospitalization for ADHF patients. However, the impact of residual congestion at discharge on worsening renal function (WRF) in both high-aged and older patients remains uncertain because previous studies of WRF in ADHF patients were conducted for older patients.
