AI Article Synopsis
- Right ventricular failure significantly worsens the prognosis of pulmonary hypertension, doubling the mortality rate.
- In a study involving 167 patients, 47.3% exhibited bendopnea, a symptom that may indicate right ventricular energy failure.
- Bendopnea effectively predicted right ventricular energy failure with notable accuracy, suggesting it could be a valuable, easy-to-use tool in clinical assessments of patients with pulmonary hypertension.
Article Abstract
Objective: The development of right ventricular failure has a significant adverse prognostic impact on the course of pulmonary hypertension. Right ventricular energy failure has been shown to double the mortality of pulmonary hypertension even after correction for many established risk predictors. We hypothesize that bendopnea may indicate right ventricular energy failure in patients with pulmonary hypertension.
Methods: We prospectively enrolled patients with pulmonary hypertension who were admitted to our pulmonary hypertension outpatient clinic between January 2021 and June 2021. Bendopnea was assessed by asking patients to bend forward and report any shortness of breath within 30 seconds. Routine physical examination, laboratory tests, echocardiography, and right heart catheterization parameters were collected.
Results: A total of 167 patients were enrolled into the study. Bendopnea and right ventricular energy failure was present in 79 (47.3%) and 43 (25.7%) patients, respectively. Bendopnea accurately predicted the presence of right ventricular energy failure (area under the curve, 0.667; 95% CI, 0.574-0.760; P < 0.001) and had a significantly superior diagnostic power compared with many other symptoms and signs.
Conclusions: Our study shows that bendopnea predicts right ventricular energy failure in patients with pulmonary hypertension and can be added to our physical examination armamentarium as an easy, rapid, and noninvasive prognostic tool.

Growth Differentiation Factor-15 Is Associated With Congestion-Related Anorexia and Weight Loss in Advanced Heart Failure.

Background: Growth differentiation factor (GDF)-15 is a pleiotropic cytokine that is associated with appetite-suppressing effects and weight loss in patients with malignancy.
Objectives: This study aims to investigate the relationships between GDF-15 levels, anorexia, cachexia, and clinical outcomes in patients with advanced heart failure with reduced ejection fraction (HFrEF).
Methods: In this observational, retrospective analysis, a total of 344 patients with advanced HFrEF (age 58 ± 10 years, 85% male, 67% NYHA functional class III), underwent clinical and echocardiographic examination, body composition evaluation by skinfolds and dual-energy x-ray absorptiometry, circulating metabolite assessment, Minnesota Living with Heart Failure Questionnaire, and right heart catheterization.
Unsupervised clustering of intraventricular hemodynamic forces for the phenotyping of left-ventricular function in non-ischemic left ventricular cardiomyopathy.

Background: Cardiac magnetic resonance (CMR) is essential for diagnosing cardiomyopathy, serving as the gold standard for assessing heart chamber volumes and tissue characterization. Hemodynamic forces (HDF) analysis, a novel approach using standard cine CMR images, estimates energy exchange between the left ventricular (LV) wall and blood. While prior research has focused on peak or mean longitudinal HDF values, this study aims to investigate whether unsupervised clustering of HDF curves can identify clinically significant patterns and stratify cardiovascular risk in non-ischemic LV cardiomyopathy (NILVC).

Right ventricular (RV) dysfunction after biventricular repair is critical in most adults with congenital heart disease (ACHD). Conventional 2D magnetic resonance imaging (MRI) measurement is considered as a 'gold standard' for RV evaluation; however, addition information on ACHD after biventricular repair is sometimes required. The reasons why adjunctive information is required is as follows: (I) to evaluate the severity of cardiac burden in symptomatic patients with normal RV size and ejection fraction (EF), (II) to determine the optimal timing of invasive treatments in asymptomatic ones, and (III) to detect proactively a potential cardiac burden leading to ventricular deterioration, from a fluid dynamics perspective.

Image reconstruction impacts haemodynamic parameters derived from 4D flow magnetic resonance imaging with compressed sensing.

Aims: 4D blood flow measurements by cardiac magnetic resonance imaging (CMR) can be used to simplify blood flow assessment. Compressed sensing (CS) can provide better flow measurements than conventional parallel imaging (PI), but clinical validation is needed. This study aimed to validate stroke volume (SV) measurements by 4D-CS in healthy volunteers and patients while also investigating the influence of the CS image reconstruction parameter on haemodynamic parameters.
