Objective: Heart failure (HF) continues to be a leading cause of hospital admissions, particularly in underserved patients. We hypothesised that providing individualised self-management support to patients and feedback on use of evidence-based HF therapies (EBT) to physicians could lead to improvements in care and decrease hospitalisations. To assess the feasibility of conducting a larger trial testing the efficacy of this dual-level intervention, we conducted the Congestive Heart failure Adherence Redesign Trial Pilot (CHART-P), a proof-of-concept, quasi-experimental, feasibility pilot study.
Setting: A large tertiary care medical centre in Chicago.
Participants: Low-income patients (
Interventions: Physicians received HF guidelines and periodic individualised feedback on their adherence to EBT. Patients received HF education, support and self-management training for diet and medication adherence by a trained nurse through 11 interactive sessions over a 4-month period. Evaluations were conducted pre-enrolment and 1 month postintervention completion.
Outcome Measures: Feasibility was assessed by the ability to deliver intervention to patients and physicians. Exploratory outcomes included changes in medication and sodium intake for patients and adherence to EBT for physicians.
Results: Eighty-seven per cent and 82% of patients received >80% of interventions at 1 month and by study completion, respectively. Median sodium intake declined (3.5 vs 2.0 g; p<0.01). There was no statistically significant change in medication adherence based on electronic pill cap monitoring or the Morisky Medication Adherence Scale (MMAS); however, there was a trend towards improved adherence based on MMAS. All physicians received timely intervention.
Conclusions: This pilot study demonstrated that the protocol was feasible. It provided important insights about the need for intervention and the difficulties in treating patients with a variety of psychosocial problems that undercut their effective care.

Assessing platelet-derived extracellular vesicles for potential as therapeutic targets in cardiovascular diseases.

Introduction: Cardiovascular disease (CVD) is the leading cause of death worldwide. Platelet-derived extracellular vesicles (PEV) have attracted extensive attention in cardiovascular disease research in recent years because their cargo is involved in a variety of pathophysiological processes, such as thrombosis, immune response, promotion or inhibition of inflammatory response, promotion of angiogenesis as well as cell proliferation and migration.
Areas Covered: This review explores the role of PEV in various cardiovascular diseases (such as atherosclerosis, myocardial infarction, ischemia-reperfusion injury, and heart failure), with relation to its molecular cargo (nucleic acids, bioactive lipids, proteins) and aims to provide new insights in the pathophysiologic role of PEV, and methods for preventing and treating cardiovascular diseases based on PEV.

Objective: To evaluate the clinical efficacy and safety of noninvasive positive pressure ventilation combined with pressure support ventilation (NPPV-PSV) in the treatment of chronic heart failure (CHF) through a meta-analysis.
Methods: A systematic search was conducted using PubMed, Embase, Web of Science, Cochrane Library, CNKI and Wanfang databases to find randomized controlled trials and cohort studies on NPPV-PSV treatment for CHF. The period of search was set from inception until 2024.
Background: The purpose of this study was to investigate whether circulating pyruvate kinase M2 (PK-M2) levels are elevated in the peripheral blood and to assess their association with diagnosis and prognosis in patients with heart failure (HF).
Methods And Results: We conducted a prospective investigation involving 222 patients with HF and 103 control subjects, measuring PK-M2 concentrations using ELISA. The primary outcome, assessed over a median follow-up of 2 years (interquartile range: 776 to 926 days), was the time to the first occurrence of either rehospitalization for worsening HF or cardiovascular death.

Background: The study investigates the prognostic impact of sex and sex-related differences in patients hospitalized with heart failure with mildly reduced ejection fraction (HFmrEF). More data regarding the characterization of patients and their outcomes in the presence of HFmrEF are needed.
Methods And Results: Consecutive patients hospitalized with HFmrEF (ie, left ventricular ejection fraction 41%-49% and signs or symptoms of HF) were retrospectively included at one institution from 2016 to 2022.
