Investigation of the Effect of Inspiratory Muscle Training and Dual-Task Inspiratory Muscle Training on Cognitive Functions in Heart Failure
Sponsor: Istanbul University - Cerrahpasa
Summary
The goal of this clinical trial is to evaluate whether dual-task inspiratory muscle training (IMT) is effective in improving cognitive and functional outcomes in adults with heart failure. It will also assess the effects of standard IMT and compare both approaches. The main questions it aims to answer are: * Does dual-task IMT improve cognitive function more than standard IMT or no intervention? * Does dual-task IMT improve respiratory function, inspiratory muscle strength, and exercise capacity? * What are the effects of dual-task IMT on symptoms such as dyspnea and fatigue, and on quality of life, anxiety, and depression? Dual-task IMT, standard IMT, and a control group (no additional intervention) will be compared to determine which approach is more effective in patients with heart failure (HF). Participants will: * Be randomly assigned to one of three groups: dual-task IMT, standard IMT, or control * Perform IMT training 5 days per week for 8 weeks (2 sessions per day, 15 minutes each) if assigned to an intervention group * Complete 1 supervised in-person session per week and 4 sessions via telerehabilitation if assigned to an intervention group * Undergo assessments before and after the 8-week intervention, including cognitive tests, respiratory function, exercise capacity, and symptom evaluations

Interventions
Dual-Task IMT
IMT will be applied using a threshold loading device at 50% of MIP for 8 weeks (5 days/week, 2 sessions/day, 15 minutes each). One session per week will be supervised, and the remaining sessions will be performed via telerehabilitation. During IMT, participants will simultaneously perform cognitive tasks targeting attention, memory, and executive functions, which will be varied weekly to minimize learning effects.
