Aim: Sodium polystyrene sulfonate (SPS) is one of the classic potassium-binding agents that remains commonly used in the treatment of hyperkalaemia. However, the potential concern about its sodium load has not been fully investigated. In this study, we evaluated the association between SPS initiation and heart failure (HF), compared with calcium polystyrene sulfonate (CPS).

Aims: The effect of initiating sacubitril/valsartan (Sac/Val) therapy during hospitalization for acute heart failure (AHF) on left ventricular (LV) remodelling remains unclear. This study aimed to assess the impact of Sac/Val on LV remodelling in patients in whom Sac/Val was initiated during AHF hospitalization.
Methods And Results: This study was a sub-analysis of the Program of Angiotensin-Neprilysin Inhibition in Admitted Patients with Worsening Heart Failure (PREMIER) study, which investigated the impact of initiating Sac/Val during hospitalization for AHF on echocardiographic parameters over an 8-week period, in comparison with the standard renin-angiotensin system inhibitor therapy (control).
Hypertension is the greatest risk factor for cardiovascular diseases and significantly contributes to cardiovascular mortality. In Japan, the hypertensive population is estimated at 43 million, with only 27% achieving well-controlled blood pressure (BP). The onset of major cardiovascular events, including stroke, myocardial infarction, heart failure, and aortic dissection, frequently occurs during the early morning hours.

Aims: Chronic kidney disease (CKD) is a growing global health concern, and sodium-glucose cotransporter 2 (SGLT2) inhibitors have emerged as a key treatment strategy. While their kidney-protective effects are well established in both genders, women are prescribed these agents less frequently than men for the treatment of type 2 diabetes worldwide. However, data on gender differences in SGLT2 inhibitor prescriptions for CKD remain limited.

Aim: Although frailty is the result of multifactorial vulnerability, such as physical, cognitive, and socio-psychological factors, the association of multifactor-defined frailty and its components with cardiovascular disease (CVD) has not been investigated. The goal of this paper is to clarify the association between multifactor-defined frailty and its components and CVD in older adults.
Methods: Using a nationwide claims database, we included 66 948 participants aged ≥65 years without a history of CVD who were assessed using a simple questionnaire-based approach covering physical, cognitive, oral, nutritional, and social aspects of frailty.
Hypertension is a major risk factor for cardiovascular diseases. This study aimed to clarify blood pressure (BP) management after the health check-up among individuals with grade II or severer hypertension, defined as systolic BP (SBP) ≥ 160 mmHg or diastolic BP (DBP) ≥ 100 mmHg in Japan. This retrospective study used the JMDC Claims Database (2005-2022) in Japan, including 63,785 individuals (median age 50 years; men 75.

Hypertension is a key modifiable risk factor contributing to elevated cardiovascular morbidity and mortality in this population. However, its prevalence and persistence remain underexplored.

Recently, lean mass index (LMI) has been demonstrated to be a precise indicator of cardiovascular disease (CVD) risk, and the newly proposed formula enabled the simple estimation of LMI without a computed tomography scan. However, little is known about its attribution to a risk of stroke.

Here, we established Syrian hamsters, a seasonal mammal, carrying loss of function of aralkylamine -acetyltransferase (AANAT), a rate-limiting enzyme in melatonin biosynthesis. Mutants showed a normal circadian period but an accelerated entrainment to rescheduled light-dark cycles.

This paper focuses on the clinical development of tissue-engineered vascular grafts (TEVGs), especially those that have progressed to clinical trials, and introduces their current status with historical background and future directions. This review was created based on a translation of the Japanese review first reported in the Japanese Journal of Artificial Organs in 2023 (vol.

In Europe and the US, several statements on the use of ECGs have already been published by related academic societies. In addition, with the relaxation of regulations on media advertising ambulatory/wearable ECG devices, the frequency of use of simple ECG devices by the general public will increase in the future.
View Article and Find Full Text PDFBackground And Aims: This study aimed to assess the prevalence of cardiac amyloidosis (CA) in patients with non-valvular atrial fibrillation (AF) and to test the hypothesis that early-stage CA can be identified through atrial biopsy.
Methods: Atrial biopsy was performed on 578 patients during AF ablation, with right ventricular (RV) biopsy conducted in 385 patients. The amyloid type was assessed using immunohistochemistry.
Aims: This study investigated the effect of uptitration of sacubitril/valsartan (Sac/Val) compared with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEIs/ARBs) on N-terminal pro-B-type natriuretic peptide (NT-proBNP) level within current guideline-directed medical therapy in acute heart failure (AHF).
Methods And Results: This was the secondary analysis in the Program Angiotensin-Neprilysin Inhibition in Admitted Patients with Worsening Heart Failure (PREMIER) study. AHF patients were allocated to switch to Sac/Val or ACEIs/ARBs, and the Sac/Val group was divided into Sac/Val with or without uptitration group (Sac/Val >24/26 mg or ≤24/26 mg twice daily at week 8).
Background: Sodium-glucose co-transporter 2 (SGLT2) inhibitors are important for treating patients with preserved left ventricular (LV) ejection fraction (LVEF). Several studies have assessed the effects of SGLT2 inhibitors on LV diastolic function, with conflicting results. In this sub-analysis of the Program of Ipragliflozin for Endothelial Dysfunction in Chronic Kidney Disease and Type 2 Diabetes (PROCEED) trial-including patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD)-we examined the effect of ipragliflozin compared with non-SGLT2 inhibitor standard therapy (control) on changes in the maximum early diastolic velocity to average early diastolic peak velocity (E/e') ratio (an index of LV diastolic function) via echocardiography.

We investigated the clinical influence of a home-based remote care program using telemonitoring and telecoaching on executive function in patients with HF and assessed the relationship between executive functional status and clinical outcomes. This prospective study enrolled outpatients with HF, and they received home-based remote care program with telemonitoring and telecoaching using self-measured physical data.

This study evaluated the impact of intensive BP-lowering on cardiovascular events in patients with diabetes compared to standard treatment. A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted, comparing intensive treatment (target systolic BP < 130 mmHg or diastolic BP < 80 mmHg) with standard treatment in patients with diabetes.

There were few data on the clinical characteristics of ST-segment elevation myocardial infarction (STEMI) patients with late presentation (long symptom onset to door [hospital arrival] time). Among 719 consecutive patients with STEMI who underwent percutaneous coronary intervention (PCI) in the SAGA-ACS registry, we compared baseline characteristics and clinical outcomes between patients with early presentation (symptom onset to door time <2.3 hours) and late presentation (≥2.

View Article and Find Full Text PDFAims: Sodium-glucose cotransporter-2 (SGLT2) inhibitors have proven kidney protective effects. Given that the SGLT2 inhibitors lower blood pressure (BP), the magnitude of their kidney benefits may vary depending on an individual's BP. Therefore, we investigated whether baseline BP modifies the effect of SGLT2 inhibitors on kidney function.

However, according to the finding from recent clinical trials with some medications such as finerenone and glucagon-like peptide-1 receptor agonist, a clinical concept of pharmacological therapy in patients with HFmrEF/HFpEF will be updated and upgraded. Based on recent evidences, we herein aim to discuss the possible roles of those medications in the HFmrEF/HFpEF therapy and propose an emerging pharmacological strategy for this population.
