Improve Cardiac Health in Heart Failure Patients with Meditation
By John M. de Castro, Ph.D.
“Not only can meditation improve how your heart functions, but a regular practice can enhance your outlook on life and motivate you to maintain many heart-healthy behaviors, like following a proper diet, getting adequate sleep, and keeping up regular exercise,” – John Denninger
Cardiovascular disease is the number one killer. A myriad of treatments have been developed for heart disease including a variety of surgical procedures and medications. In addition, lifestyle changes have proved to be effective including quitting smoking, weight reduction, improved diet, physical activity, and reducing stresses. Unfortunately, for a variety of reasons, 60% of cardiovascular disease patients decline to alter these lifestyle factors, making these patients at high risk for another attack.
Congestive heart failure (CHF) is a major type of cardiovascular disease. “CHF is a chronic progressive condition that affects the pumping power of your heart muscles. While often referred to simply as “heart failure,” CHF specifically refers to the stage in which fluid builds up around the heart and causes it to pump inefficiently” (Healthline). Heart failure is a very serious life-threatening condition. About 5.7 million adults in the United States have congestive heart failure. One in 9 deaths include heart failure as a contributing cause. The seriousness of heart failure is underscored by the fact that about half of people who develop heart failure die within 5 years of diagnosis. Hence, effective treatment is very important.
Mindfulness trainings such as meditation practice are known to help with a wide range of physical and psychological problems, including heart failure. So, it would make sense to further investigate the ability of meditation practice to the improve the health and longevity of patients with heart failure.
In today’s Research News article “Meditation for Improved Clinical Outcomes in Patients with Implantable Defibrillators for Heart Failure- Pilot Study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7533122/ ) Aditee and colleagues recruited adult patients with heart failure and an implantable cardioverter defibrillator. They were randomly assigned to receive either 6 months of focused meditation or treatment as usual. Breath following meditation was trained in 3 session during the first week and then once every 2 weeks for 6 months. They were encouraged to meditate at home daily. They were measured before and after training and then yearly for 7 years for a 6-minute walk, brain natriuretic peptide (BNP) levels, atrial fibrillation, mortality, heart failure hospitalization and ventricular arrhythmias.
They found that in comparison to baseline and the treatment as usual group, the meditation group had significantly fewer atrial fibrillations and ventricular tachycardias which remained true 7 years later. Although at the 7-year follow-up 67% in treatment as usual group vs 87.5% in meditation group were still alive, this difference was not statistically significant. Hence, meditation practice appears to improve cardiac function in heart failure patients.
This was a pilot study that was not sufficiently powered to detect small differences. So, the fact that cardiac function was significantly improved by meditation was particularly significant. Had a greater number of participants been included, the reduced mortality may have also been significant. Future studies should include an active control condition and a greater number of participants. Regardless, it is clear that meditation is good for heart failure patients. Since stress aggravates the condition, perhaps the improved cardiac function in the meditators was due to the known ability of meditation to improve the physiological and psychological responses to stress.
So, improve cardiac health in heart failure patients with meditation.

Abstract
Background
Sympathetic activation is associated with congestive heart failure (CHF) and leads to adverse clinical events. We hypothesized that meditation by reducing emotional reactivity would have beneficial effect in reducing arrhythmias compared to control patients.
Methods
Patients known to have CHF and implantable cardioverter defibrillators (ICD) were randomized to Vipassana meditation or usual care control group. Meditation group underwent meditation classes three times during the first week, thereafter every once two weeks. They were encouraged to practice meditation at least once everyday. The ICD was followed by clinic/ remote visits. Atrial (AA) and ventricular arrhythmias (VA) as well cardiac events were assessed in follow up. Chi square test was used to compare nominal variables and t test for continuous variables.
Results
Patients (n=25, 65% male, mean LVEF 25%, HTN 38%, Diabetes 12%, coronary artery disease 38%, NYHA class 2.2) were followed for 79 + 36 months. Comparing meditation vs control, survival was higher (88%vs 67%); there was less cumulative sustained AF episodes (mean 0.9, IQR 0-1 vs 2.5, IQR 2-4, p=0.045), sustained VT occurred (25% vs 55%, amiodarone use (none vs 44%), and VT ablation in 6.6% vs 33% in the meditation group.
Conclusions
In this first pilot study of meditation in CHF patients with ICD, during long term follow up, there is a trend for improved survival and reduced arrhythmias in patients randomized to meditation.
