Heart failure is typically caused by different cardiovascular conditions and has a poor prognosis. Despite the advances in treatment in recent decades, heart failure has remained a major cause of morbidity and mortality worldwide. As revealed by and experiments, inflammation plays a crucial role in adverse cardiac remodeling, ultimately leading to heart failure. Macrophages are central to the innate immune system, and they are the most indispensable cell type for all cardiac injuries and remodeling stages. The immediate microenvironment regulates their polarization and secretion. In this review, we summarize the phenotypic heterogeneity and governing roles of macrophages in the infarcted, inflamed, and aging heart and assess their significance as potential therapeutic targets in heart failure. We also highlight the current missing links and major challenges in the field that remain to be addressed before macrophages can be exploited for therapeutic applications.

Experience with sodium glucose cotransporter-2 inhibitors in adult patients with Fontan circulation.
Adv Clin Exp Med
January 2025
Institute of Cardiology, Jagiellonian University Medical College, Cracow, Poland.
Background: We still know little about the effective pharmacological treatment of heart failure (HF) associated with the Fontan circulation. One of the new options may be sodium glucose cotransporter-2 inhibitors (SGLT2i), which have been proven effective in classic forms of left ventricular HF.
Objectives: To evaluate the effect and safety of SGLT2i inclusion in adults with Fontan circulation.
Epidemiologic and clinical characteristics and course of acute heart failure and cardiogenic shock diagnosed in emergency departments.
Emergencias
December 2024
Servicio de Urgencias, Hospital Clínic Barcelona, IDIBAPS, Universitat de Barcelona, España.
Objective: To describe the characteristics of patients diagnosed with acute heart failure (AHF) in emergency departments (EDs) who develop cardiogenic shock (CS) not associated with ST-segment elevation acute coronary syndrome (STACS).
Methods: Information for patients diagnosed with AHF in 23 Spanish EDs and registered between 2009 and 2019 were included for analysis if the patients developed symptoms consistent with CS. We described baseline clinical characteristics related to cardiac decompensation and CS, as well as 30-day mortality.
Cardiovascular health and risks of atrial fibrillation and its prognosis.

School of Population Medicine and Public Health, Chinese Academy of Medical Sciences & Peking Union Medical College, Beijing, China.
Background: Atrial fibrillation (AF) is the most common cardiac arrhythmia around the world with an increased risk of a broad spectrum of adverse comorbidities and death. Whether cardiovascular health (CVH) is associated with AF development remains unclear.
Methods: 238,420 participants without cardiovascular disease at baseline were selected from the UK Biobank study cohort from 2006 to 2010.
Urinary albumin-to-creatinine ratio as an independent predictor of long-term mortality in atherosclerotic cardiovascular disease patients: A propensity score-matched study: UACR and Long-term Mortality in ASCVD.
Am J Prev Cardiol
March 2025
Department of Cardiology, Hangzhou TCM Hospital Affiliated to Zhejiang Chinese Medical University, Hangzhou, Zhejiang, PR China.
Background And Aims: Atherosclerotic cardiovascular disease (ASCVD) is a leading cause of mortality, and while the association between the urinary albumin-to-creatinine ratio (UACR) and cardiovascular risk is recognized, the specific impact of UACR on the long-term survival of ASCVD patients remains not fully understood. The aim of this study is to investigate the influence of UACR on the long-term risk of all-cause mortality in patients with ASCVD.
Methods: This study included ASCVD patients from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018.
Baseline fibroblast growth factor 23 predicts incident heart failure and cardiovascular mortality in patients with chronic kidney disease: A 3-year follow-up study.
Int J Cardiol Heart Vasc

Department of Nephropathy, the First Affiliated Hospital of Anhui Medical University, Hefei, Anhui, People's Republic of China.
Background: Heart failure (HF) is a significant cause of death among patients with chronic kidney disease (CKD). Emerging data suggest a crucial role of fibroblast growth factor 23 (FGF23) in the pathogenesis of HF in CKD patients. The present study aimed to investigate whether the serum intact FGF23 (iFGF23) level is elevated when ejection fraction (EF) is preserved and to evaluate its predictive value for incident HF and cardiac mortality in CKD patients with preserved EF.
