Glittre-ADL test to assess functional capacity in patients with heart failure and reduced ejection fraction: Reproducibility, minimal detectable change, and cutoff point.

Background: Cardiopulmonary exercise testing (CPET) is the gold standard for functional capacity assessment, although it is costly and not easily accessible. The Glittre-ADL test may be a low-cost alternative for patients with heart failure.

Objective: To establish a cutoff point for functional capacity of patients with heart failure using the Glittre-ADL test.

Correlation between peripheral endothelial function, oxygen consumption and ventilatory efficiency in heart transplantation recipients.

Background: Endothelial dysfunction and peak oxygen uptake (VO) are also predictors of increased risk of cardiovascular events in heart transplantation (HTx) recipients. The preservation of endothelial function may contribute to exercise tolerance.

Objective: To investigate the correlation between peripheral endothelial function and exercise tolerance through VO and ventilation to carbon dioxide production slope (VE / VCO) in HTx recipients.

Endothelial function, arterial stiffness and heart rate variability of patients with cardiovascular diseases hospitalized due to COVID-19.

Background: The novel coronavirus disease (COVID-19) may cause vascular (e.g., endothelial dysfunction, and arterial stiffness), cardiac, autonomic (e.

Association between performance on the Glittre ADL-test and the functional capacity of patients with HF: A cross-sectional study.

: The Weber classification based on peak VO is a well-established method for categorizing patients with heart failure (HF) regarding severity. However, other submaximal tests such as the Glittre ADL-Test have been gaining prominence in practice due to a coherent and more comprehensive correlation with limitations for performing activities of daily living in patients with heart failure.: To investigate the correlation between the time required to perform the Glittre ADL-Test and the peak VO in patients with HF.

Effect of exercise on endothelial function in heart transplant recipients: systematic review and meta-analysis.

Endothelial dysfunction is associated with increased cardiovascular risk and death in heart transplant recipients (HTx). Although the measurement of peripheral endothelial function is considered a significant predictor of cardiovascular events in several populations, few studies have investigated this outcome after therapeutic strategies, including different exercise types, duration, and intensity. This systematic review and meta-analysis aimed to investigate the effects of continuous moderate exercise (CON) or high-intensity interval training (HIIT) to improve endothelial function (EF) in HTx.

Effectiveness of inspiratory muscle training on sleep and functional capacity to exercise in obstructive sleep apnea: a randomized controlled trial.

Purpose: The aim of this study was to evaluate the effectiveness of inspiratory muscle training (IMT) on sleep and functional capacity to exercise in subjects with obstructive sleep apnea (OSA).

Methods: This is a controlled, randomized, double-blind study conducted in 16 OSA patients divided into two groups: training (IMT: n = 8) and placebo-IMT (P-IMT: n = 8). IMT was conducted during 12 weeks with a moderate load (50-60% of maximal inspiratory pressure-MIP), while P-IMT used a load < 20% of MPI.

[Ophthalmologic findings in cardiac transplant recipients].

Purpose: To evaluate findings of ophthalmologic examinations in cardiac transplant recipients, searching especially for changes in the retinal nerve fiber layer by means of Scanning Laser Polarimetry.

Methods: Fifteen cardiac transplant recipients were examined from September 2003 to July 2004. All of them underwent ophthalmologic examination, which consisted of visual acuity (VA), biomicroscopy, tonometry and fundoscopy.
