Effect of Resistance Training in Patients on the Waiting List for Heart Transplant

Heart Failure Clinical Trial

Official title: Effect of Resistance Training on Functional Capacity, Quality of Life and Cardiac Biomarkers in Patients on the Waiting List for Heart Transplant: a Randomized and Controlled Clinical Trial

Status Recruiting

Clinical Trial Summary

The present longitudinal, randomized, and blinded clinical trial aims to: - Evaluate the effects of resistance training on the functional capacity, quality of life, and cardiac biomarkers of hospitalized patients with heart failure (HF) on the waiting list for heart transplantation (HTx). - Evaluate the associations between Fried's frailty classification and functional capacity responses to resistance training. The protocol will have a total duration of 12 weeks.

Clinical Trial Description

Heart failure (HF) presents a significant challenge to contemporary healthcare systems. As HF progresses, heart transplantation (HTx) becomes the primary treatment option to enhance survival rates. Patients awaiting HTx often endure extended hospitalizations and rely on continuous inotropic support. This scenario exacerbates bed rest and potentially worsening functional capacity. Resistance training has shown promise in mitigating the detrimental effects of immobility, however, limited research has explored its impact on HF patients on the HTx waiting list. Objectives: - To evaluate the effects of resistance training on functional capacity, quality of life, and cardiac biomarkers in hospitalized patients with HF on the HTx waiting list. - To assess the associations between Fried's frailty phenotype and functional capacity responses to resistance training, hemodynamic behavior during the protocol, and the incidence of adverse events during the protocol implementation. Methods: A total of 50 patients hospitalized on the HTx waiting list will be recruited for this study. Participants will be randomly assigned to one of two groups: the resistance training group (TG) and the control group (CG). Assessments will occur at three time points: baseline (T0), at 6 weeks (T1), and at 12 weeks (T2) of resistance training. Clinical parameters will be evaluated, including the six-minute walk test and the Short Physical Performance Battery. Peripheral muscle strength will be measured using a dynamometer, and inspiratory muscle strength will be assessed through maximum inspiratory pressure. Quality of life will be evaluated using the Kansas City Cardiomyopathy Questionnaire-12. Additionally, cardiac biomarkers, such as exhaled air ketone and brain natriuretic peptide levels in venous blood samples, will be analyzed. ;
