February is American Heart Month! In addition to the benefits of nutrition and exercise in those with existing heart disease and in the area of prevention, mindfulness has a strong role to play. Hope you will take a moment to see the benefits below as a part of a heart healthy lifestyle.
Cardiovascular Benefits of Mindfulness
Mindfulness Based Interventions (MBI’s) may offer many psychological, physiological, cognitive and behavioral changes that have positive benefits for patients with cardiovascular disease. There may also be a role in preventing these diseases or decreasing the likelihood of the progression of heart disease. MBI’s are designed to assist participants to learn non-judgmental sustained, moment to moment awareness of physical sensations, emotional states and thoughts. The core practices are focused attention training – re-directing attention to a chosen anchor and open awareness training – cultivating an attitude of open acceptance to what is noticed in emotional states, patterns of behavior, and thoughts. Over the last 40+ years, these practices have been shown to elicit the “relaxation response”, a termed coined by the late Harvard Medical School professor and cardiologist, Dr. Herbert Benson.
These potential benefits lie in the mechanisms of:
• Reduced sympathetic nervous system activity, (which includes a decrease in the “fight or flight” mode, decreased blood pressure, specifically systolic BP, and decreased heart rate). This is the same activity reduced by beta-blockers, a common cardiac medication.
• Improved vagal control (increasing the body’s ability to manage stress better, lower heart rate and decrease inflammation).
• Decreased psychological distress, which is common among patients with CVD. Studies have shown that patients with acute MI are 3x more likely to suffer from depression and increase in recurrent cardiac events and mortality. Lower levels of stress have been shown to improve mortality rates post MI.
• Beyond the above, there are also benefits seen assisting patients in decreasing emotional reactivity, negative thoughts and feelings and leading to improved depression and anxiety.
• There have even been small-moderate effects seen in decreased binge and impulsive eating in adults with obesity.
• There is moderate evidence that learning these life skills can lead to - improved sleep patterns – important as poor sleep is a risk factor, quite significant, for heart disease, stroke, HBP, diabetes and obesity.
• Improved cognitive function – this was even seen in adults with mild cognitive impairments.
Much more research is needed and is ongoing to continue to learn how to provide specific recommendations for cardiac patients and the public, but the research is leading in the right direction. As these practices are not for all people, and not without risk, like other psychological interventions, a monitored program such as Mindfulness Based Stress Reduction (MBSR) is a good option. With a very vigorous process looking at medical and psychological history, participants are appropriately screened for the program, instructed by trained teachers and followed for the duration of the 8-week program.
