Abstract Background: In transthyretin amyloid cardiomyopathy (ATTR-CM), the assessment of functional capacity is of great importance. A distance < 300m covered in the 6-minute walk test (6MWT) is linked to a poorer prognosis in heart failure (HF) patients. However, in ATTR-CM, this association is not well-established, particularly among its various presentations and variants. Objectives: To evaluate functional capacity and, the prognostic value of the 6MWT in patients with ATTR-CM and to identify their clinical characteristics according to the type of […]

Abstract Background Pathologies involving the heart are still the main causes of death, and acute myocardial infarction (AMI) is consistently present in this index. The two-minute walk test (2MWT) is ideal for assessing the functional capacity of this patient. Objective To describe the feasibility of the 2MWT in older people after AMI. Methods This is a cross-sectional study. At hospital discharge, patients were invited to perform the 2MWT. Before starting the test, systolic blood pressure (SBP), diastolic blood pressure (DBP), […]

Abstract Background: Cardiac resynchronization therapy (CRT) is an effective treatment for patients with heart failure. Objective: To evaluate the response of CRT in maximal inspiratory pressure (MIP), peak expiratory flow (PEF), and exercise tolerance as determined by the six-minute walk test (6MWT) in patients with HF. Methods: This study used the 6MWT and Manovacuometer to assess functional capacity in relation to activities of daily living, in which fatigue and dyspnea are common. Results: After six months of CRT, this study […]

The cardiopulmonary exercise testing (CPET) is known to be the gold standard method for the assessment of functional capacity. However, the method is expensive, often not well tolerated by the patients, and may not be a good strategy to evaluate activities of daily living (ADL). Functional tests are indirect method to assess functional status or functional capacity of an individual to perform ADL and meet their metabolic demands. These tests are considered objective measures that can monitor the clinical course […]

Abstract Background: Few studies have used portable gas analyzers during the 6-minute walk test (6MWT) in patients with heart failure and normal ejection fraction (HFNEF). Objectives: To analyze the kinetics of hemodynamic, ventilatory, and metabolic variables in patients with HFNEF during the T6m using a portable gas analyzer. Methods: Prospective, analytical study with an intentional, non-probabilistic, convenience sample. In total, 24 patients with HFNEF and past hospital admissions due to a clinical diagnosis of heart failure (HF) were included using […]
