Heart failure (HF) is a common condition and one of the main morbidity and mortality factors in elderly patients. The incidence of HF progressively increases with age, reaching >10% in those aged 70 years or over. In the elderly population, both the diagnosis and the management of HF prove challenging, often requiring specialized care and a multidisciplinary approach. In seniors, atypical presentation of HF is much more common than in younger patients; thus, a holistic assessment with biomarkers related to HF allows for early diagnosis and accurate risk stratification in this group of patients. This article reviews the clinical and diagnostic differences in elderly patients with HF, highlighting the presence of comorbidities, frailty, cognitive impairment, and polypharmacy, as well as discussing potential biomarkers that may have clinical application in this population.

Background: Diagnosing and predicting outcomes in elderly patients with heart failure (HF) is challenging due to atypical symptoms and the limited value of natriuretic peptides, highlighting the need to search for new risk stratification biomarkers in this population. Aim: We aimed to analyze factors associated with the composite endpoint (all-cause mortality or decompensated HF-related hospitalization) within six months of follow-up in elderly patients with left ventricular systolic dysfunction and decompensated HF, with particular emphasis on copeptin concentration. Methods: This is a retrospective observational study based on prospectively collected data of 279 consecutive elderly patients hospitalized between 2018 and 2023 due to decompensated HF. Inclusion criteria were age > 65 years, history of HF diagnosed at least two years before the index hospitalization, and left ventricular ejection fraction < 40% on admission echocardiography. Serum copeptin levels were measured using an Enzyme-Linked Immunosorbent Assay (ELISA) (Human Copeptin ELISA kit, Sunred Biological Technology Co, Shanghai, China). The primary endpoint was all-cause mortality or decompensated HF-related hospitalization during the six-month follow-up. Results: The median age of the study population was 77 years (IQR: 69–79), and 221 (79.2%) were male. The composite endpoint occurred in 110 patients (38.1%). Multivariable analysis showed that serum concentrations of copeptin [hazard ratio (HR) 1.053 (1.042–1.064), p < 0.0001], bilirubin [HR 1.085 (1.057–1.114), p < 0.0001], uric acid [HR 1.005 (1.003–1.006), p < 0.0001], high-sensitivity C-reactive protein (hs-CRP) [HR 1.208 (1.088–1.342), p < 0.0001], and sodium [HR 1.111 (1.025–1.203), p = 0.01], as well as ischemic etiology of HF [HR 3.969 (2.396–6.575), p < 0.0001], were independently associated with worse outcomes. Conclusions: Our study demonstrated that higher concentrations of copeptin, bilirubin, hs-CRP, and uric acid, as well as lower sodium levels and ischemic etiology of HF, were independently associated with all-cause mortality or HF-related hospitalization during a six-month follow-up in elderly patients with decompensated HF.

Background/Objectives: Cognitive impairment (CI) is a common complication of heart failure (HF) that undermines self-care, adherence, and outcomes. This systematic review assessed the cognitive effects of pharmacological HF management and related cardiovascular therapies, identifying potential risks and benefits. Methods: Following PRISMA 2020, we searched PubMed, EMBASE, and Scopus for articles published in English between 1 January 2010 and 31 January 2025 (last search 31 January 2025). We included RCTs and cohort studies in adults with HF or high cardiovascular risk that reported cognitive outcomes. Non-pharmacological interventions, studies without relevant cognitive endpoints, and non-original research were excluded. Risk of bias was assessed using RoB 2 for RCTs and the Newcastle–Ottawa Scale for observational studies. Due to heterogeneity in study designs and cognitive measures, results were synthesized qualitatively without meta-analysis. Results: Of 530 records screened, 11 studies encompassing 58,190 participants met the inclusion criteria. Intensive blood pressure (BP) lowering was consistently associated with reduced risk of mild cognitive impairment or dementia compared with standard BP control. In HF populations, sacubitril/valsartan showed no adverse cognitive effects versus other RAAS inhibitors. Across RCTs and observational studies, β-blockers, ACE inhibitors, ARBs, diuretics, and statins showed no evidence of significant cognitive impairment. Comparisons of anticoagulants (dabigatran vs. warfarin; warfarin vs. aspirin) revealed no differences in cognitive trajectories, while optimized medical therapy was associated with parallel improvements in cognitive scores, left ventricular function, and renal parameters. Limitations: Evidence remains constrained by heterogeneity in study design and cognitive assessment tools (often brief screening instruments), inconsistent reporting, and generally short follow-up durations, which may obscure subtle or long-term effects. Conclusions: Contemporary pharmacological therapies for HF appear cognitively safe. Intensive BP control may confer cognitive benefit in high-risk populations, while guideline-directed treatments show no consistent evidence of cognitive harm. Optimized medical therapy may even support cognitive improvement alongside cardiac and renal recovery. Routine cognitive assessment should be integrated into HF care to support individualized management.

Patients with cancer are prone to develop pulmonary embolism (PE) in the course of cancer-associated thrombosis. These patients have increased risk of both recurrent venous thromboembolism and major bleeding. Pulmonary embolism treatment in the cancer patient group is challenging. Selection of...
