Comparing breathing exercises for heart failure patients
Therapeutic Effects of CardioBreath Aplication Versus Inspiratory Muscle Training (IMT) on Vagal Cardiac Modulation, Pulse Wave Velocity Maximal Respiratory Pressures in Heart Failure Patients: Cross-over Randomized Control Trial
This study is testing a new breathing app called CardioBreath to see if it helps heart failure patients breathe better compared to traditional breathing exercises.

What this trial studies
This study evaluates the effectiveness of a new breathing app, CardioBreath, against traditional Inspiratory Muscle Training (IMT) in patients with congestive heart failure (CHF). It focuses on the impact of these breathing techniques on respiratory muscle strength, cardiac vagal modulation, arterial stiffness, and diaphragm thickness. The study will recruit post-discharge CHF patients and utilize a crossover randomized control design to compare the two interventions. Participants will be monitored using advanced cardiovascular assessment tools to measure various health outcomes.
Who should consider this trial
Good fit: Ideal candidates are adults aged 40 to 70 with reduced ejection fraction heart failure who have access to a mobile device.
Not a fit: Patients with active smoking habits, a BMI under 30, sleep apnea, congenital heart failure, or valve disease may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide a novel, accessible method for improving respiratory and cardiovascular health in heart failure patients.
How similar studies have performed: Previous studies have shown positive outcomes with breathing exercises in heart failure management, suggesting potential success for this approach.
