Trial Summary

Will I have to stop taking my current medications?

The trial excludes participants who are on medications that interfere with heart rate variability, so you may need to stop taking such medications to participate.

What data supports the effectiveness of the treatment Heart Focused Breathing, Music Listening Control (MLC)?

Research shows that controlled breathing can improve heart rate variability (the variation in time between heartbeats) and lower blood pressure, which may help people with heart conditions. Additionally, breathing training has been found to reduce anxiety and breathing difficulties in patients with heart failure.12345

Is Heart Focused Breathing safe for humans?

Heart Focused Breathing, also known as heart rate variability biofeedback, has been studied in various settings and appears to be safe for humans. It has been shown to improve heart function and reduce anxiety without causing harmful effects.678910

How does Heart Focused Breathing differ from other treatments for heart conditions?

Heart Focused Breathing is unique because it involves controlled breathing techniques that can influence heart rate and autonomic nervous system activity, unlike traditional treatments that may rely on medication. This method can increase sympathetic stimulation of the heart, potentially offering therapeutic benefits by altering heart rate variability and autonomic tone.1112131415

What is the purpose of this trial?

This trial tests a program where caregivers of Alzheimer's patients learn techniques to reduce stress. The goal is to see if this method is practical and if it helps improve their well-being.

Findings from Research

Meditation practices have been shown to significantly improve psychosocial factors, quality of life, and reduce heart failure symptom burden in patients, based on a review of six studies involving 320 heart failure patients.
Despite the positive findings, the studies varied widely in their design and outcome measures, highlighting the need for more standardized and larger trials to better understand the effects of meditation on heart failure outcomes.
Meditation interventions among heart failure patients: An integrative review.Viveiros, J., Chamberlain, B., O'Hare, A., et al.[2022]
Heart rate variability biofeedback (HRV-BF) significantly reduced hospital readmissions (12% vs. 25.42%) and emergency visits (13.33% vs. 35.59%) in patients with coronary artery disease over a 1-year period, indicating its effectiveness in improving cardiovascular prognosis.
The HRV-BF group showed long-term improvements in cardiac autonomic function and reductions in depression and hostility, suggesting that HRV-BF is a beneficial intervention for both psychological and physiological health in cardiac rehabilitation.
One-Year Cardiovascular Prognosis of the Randomized, Controlled, Short-Term Heart Rate Variability Biofeedback Among Patients with Coronary Artery Disease.Yu, LC., Lin, IM., Fan, SY., et al.[2021]
In a study of 107 patients with stable chronic heart failure, heart-focused anxiety was primarily predicted by self-reported anxiety levels and quality of life, highlighting the importance of psychological factors in these patients.
Additionally, factors such as conscientiousness, physical activity, and renal function (measured by estimated glomerular filtration rate, eGFR) were also found to be significant predictors of heart-focused anxiety, suggesting that both lifestyle and medical indicators can help identify patients at risk for adverse outcomes.
