Purpose Of Review: Chronic kidney disease (CKD) is highly prevalent in patients with heart failure and reduced ejection fraction (HFrEF), representing a major factor of adverse outcomes. In clinical practice, it is one of the main reasons for not initiating, not titrating, and even withdrawing efficient heart failure drug therapies in patients.
Recent Findings: Despite limited data, studies show that HFrEF therapies maintain their benefits on cardiovascular outcomes in patients with CKD. Most HF drugs cause acute renal haemodynamic changes, but with stabilisation or even improvement after the acute phase, thus with no long-term worsening of the renal function. In this expert opinion-based paper, we challenge the pathophysiology misunderstandings that impede HF disease-modifying therapy implementation in this setting and propose a strategy for HF drug titration in patients with moderate, severe, and end-stage chronic kidney disease.

Phase angle in bioelectrical impedance analysis for assessing congestion in acute heart failure.
PLoS One
January 2025
Cardiovascular Center, Division of Cardiology, Korea University Guro Hospital, Seoul, Republic of Korea.
Background: The phase angle (PhA) in bioelectrical impedance analysis (BIA) reflects the cell membrane integrity or body fluid equilibrium. We examined how the PhA aligns with previously known markers of acute heart failure (HF) and assessed its value as a screening tool.
Methods: PhA was measured in 50 patients with HF and 20 non-HF controls along with the edema index (EI), another BIA parameter suggestive of edema.
Permanent Left Bundle Branch Area DF-4 Defibrillator Lead Implantation-Feasibility, Procedural Caveats, Safety, and Follow-Up.

Introduction: Permanent implantation of a DF-4 implantable cardiac defibrillator (ICD) lead in the left bundle branch area (LBBA-ICD) is the next paradigm in amalgamating cardiac resynchronization therapy (CRT) and defibrillation. We systematically investigated feasibility/success rate, procedural caveats, and complications associated with a permanent DF-4 LBBA ICD implant and pertinent data at short-term follow-up.
Methods: We prospectively attempted implantation of 7 Fr Durata (Abbott, Chicago, IL, USA) single coil DF-4 ICD lead at the LBBA using a fixed-curve non-deflectable CPS locator delivery sheath.
Hypertrophic heart failure promotes gut dysbiosis and gut leakage in interleukin 10-deficient mice.

Heart failure (HF) is a leading cause of death worldwide. We have shown that pressure overload (PO)-induced inflammatory cell recruitment leads to heart failure in IL-10 knockout (KO) mice. However, it's unclear if PO-induced inflammatory cells also target the gut mucosa, causing gut dysbiosis and leakage.

University of Tennessee Knoxville, College of Nursing, Knoxville, Tennessee, USA.
Background: Cognitive impairment and limited health literacy are prevalent among patients with heart failure, particularly those residing in rural areas, and are linked to poor health outcomes. Little is known about the intricate relationships among cognitive function, health literacy, and rehospitalization and death in rural patients with heart failure.
Objectives: To determine the relationships among cognitive function, health literacy, and cardiac event-free survival (ie, heart failure hospitalizations and cardiac mortality) in rural patients with heart failure.
Epidemiological characteristics and risk factors for heart failure in Japanese patients with type 2 diabetes: A retrospective analysis of the J-DREAMS database.
J Diabetes Investig
January 2025
Department of Diabetes, Endocrinology and Metabolism, Center Hospital, National Center for Global Health and Medicine, Tokyo, Japan.
Aim: To determine the epidemiological characteristics and risk factors for heart failure (HF) among Japanese patients with type 2 diabetes.
Methods: A retrospective cohort analysis, using J-DREAMS database, was conducted from December 2015 to January 2020 with type 2 diabetes. The primary objectives were to describe patient characteristics stratified by HF history at baseline and new HF events during follow-up.
