Patients with cancer are often treated with potentially cardiotoxic chemotherapeutics. Cardiotoxicity ranges from relatively benign arrhythmias to serious conditions such as myocardial ischemia/infarction, congestive heart failure, and cardiomyopathy. In spite of different diagnostic methods, with echocardiography as a gold standard, there is an intensive search for new diagnostic tools for the early detection of myocardial abnormalities. Available data suggest that the levels of circulating cardiomarkers can monitor the extent and severity of the myocardial damage. The role of routinely used cardiomarkers is controversial and limited in this setting. Natriuretic peptides have shown promising results in assessment and monitoring of both acute and late clinical and subclinical damage of the myocardium in association with chemotherapy. This article reviews clinical studies evaluating the role of natriuretic peptides in the early diagnosis of anthracycline cardiotoxicity, and their use in the management of cancer survivors.

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.
Evaluation of urinary density as a biomarker for the diagnosis of acute heart failure.

Department of Nephrology, Ministry of Health Tarsus State Hospital, Mersin, Turkey.
Background: Heart failure (HF) has become a public healthcare concern with significant costs to countries because of the aging world population. Acute heart failure (AHF) is a common condition faced frequently in emergency departments, and patients often present to hospitals with complaints of breathlessness. The patient must be evaluated with anamnesis, physical examination, blood, and imaging results to diagnose AHF.

Eur J Med Res
January 2025
Department of Cardiology, Zhongshan Hospital, Fudan University, Shanghai Institute of Cardiovascular Diseases, Shanghai, China.
Background: Apical hypertrophic cardiomyopathy (AHCM) is a subtype of hypertrophic cardiomyopathy (HCM). The expression level of high-sensitive cardiac troponin T (hs-cTNT) and N-terminal pro-BNP (NT-proBNP) in AHCM patients, and these relationships between echocardiography parameters were still unclear.
Methods: We retrospectively screened AHCM patients between January 2019 and December 2021 in Zhongshan Hospital Fudan University.

Department of Medicine, Ordos Institute of Technology, Ordos, 017000, China.
Objective: To observe how cognitive behavioral intervention affects physical symptoms, B-type Natriuretic Peptide (BNP), Red Cell Distribution Width (RDW), and C-reactive Protein (CRP) in elderly patients with heart failure.
Methods: Convenient sampling method was used to select 98 elderly heart failure patients who visited our hospital from January 2022 to December 2020. Patients were divided into a control group and an observation group using the red and blue ball method, with 49 cases in each group.
Evidence-Based Application of Natriuretic Peptides in the Evaluation of Chronic Heart Failure With Preserved Ejection Fraction in the Ambulatory Outpatient Setting.
Circulation
January 2025
Department of Cardiovascular Medicine, Mayo Clinic, Rochester, MN (Y.N.V.R., A.T., M.M.R., B.A.B.).
Background: Plasma NT-proBNP (N-terminal pro-B-type natriuretic peptide) is commonly used to diagnose heart failure with preserved ejection fraction (HFpEF), but its diagnostic performance in the ambulatory/outpatient setting is unknown because previous studies lacked objective reference standards.
Methods: Among patients with chronic dyspnea, diagnosis of HFpEF or noncardiac dyspnea was determined conclusively by exercise catheterization in a derivation cohort (n=414), multicenter validation cohort 1 (n=560), validation cohort 2 (n=207), and a nonobese Japanese validation cohort 3 (n=77). Optimal NT-proBNP cut points for HFpEF rule out (optimizing sensitivity) and rule in (optimizing specificity) were derived and tested, stratified by obesity and atrial fibrillation.
