Article Abstract
Background And Aims: To explore efficacy and safety of a modified dosage regimen of nesiritide in patients (≥75 years) with acute heart failure (AHF).
Methods: Total 140 patients (≥75 years) with AHF were enrolled in this study. They were randomly and evenly divided into two group--control and nesiritide group. The control group received only conventional treatment for AHF, while the nesiritide group received conventional treatment plus a continual intravenous infusion of nesiritide at a rate of 0.0075-0.015 μg·kg(-1)·min(-1) for 10-15 hours (total 0.5- 1.0 mg) once daily for 13 days.
Results: Medical research council scales in nesiritide group were significantly lower than those in control group on day 4, 8 and 14. Scores of edema had no significant difference, but were lower in nesiritide group on day 8 and 14. The nesiritide group had markedly more net body fluid losses. NT-proBNP, serum creatinine, blood pressure, cTnI, 30-day and 60-day mortality had no significant difference between two groups.
Conclusions: Nesiritide resulted in improvements in dyspnea and edema, and similar adverse effects compared with conventional treatment. In spite of no reduction on short-term mortality and a reversible influence on renal function, nesiritide was still an important choice for the elderly (≥75 years) with AHF.

: It is unknown how early exercise therapy combined with acupuncture (AP) affects the speed of recovery in patients suffering from heart failure with reduced ejection fraction (HFrEF) who are hospitalized due to worsening HF. : A prospective, sham-procedure-controlled, double-blind, randomized clinical trial with three patient groups was conducted. The study included patients with HFrEF who were hospitalized for worsening HF.

: Treprostinil, which is administered via continuous subcutaneous or intravenous infusion, is a medication applied in the treatment of pulmonary arterial hypertension (PAH). The dose of treprostinil is adjusted on an individual basis for each patient. A number of factors determine how well patients respond to treatment.

The soluble suppression of tumorigenesis 2 protein (Soluble Suppression of Tumorigenesis 2 (sST2)) has emerged as a promising biomarker linked to cardiac remodeling and fibrosis. This study investigates Soluble Suppression of Tumorigenesis 2 (sST2)'s potential as a diagnostic and prognostic marker for chronic heart failure (CHF) and explores its clinical utility in predicting outcomes.

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.

Aims: This study aimed to identify factors associated with frailty in heart failure (HF) patients, focusing on demographic, biochemical and health-related variables. It also explored the correlation between frailty and comorbidities such as malnutrition, cognitive impairment and depression, assessing how these factors interact to influence frailty risk.
Methods: A total of 250 HF patients (mean age 73.
