Effects of Reiki on Autonomic Activity Early After Acute Coronary Syndrome. Rachel S.C. Friedman, Matthew M. Burg, Pamela Miles, Forrester Lee, and Rachel Lampert J. Am. Coll. Cardiol. 2010;56;995-996.
Heart rate variability (HRV) is a measure that is closely watched in the days after a heart attack. The study linked above showed Reiki can help improve this critical measure.
The study was published in the most prestitigious peer-reviewed conventional cardiology journal. Patients who received a 20-minute Reiki treatment within three days after suffering a heart attack showed improved mood and heart rate variability.
Let’s take a look at what this means in nontechnical language.
A heart attack is a stressful event which, like other stressful events, causes a stress response. A stressed body is less resilient, less able to cope with more stress. This means a patient who has just had a heart attack has a higher risk of having another one. Doctors are well aware of this dangerous cycle, and helping the body recover its resilience is a primary goal in cardiac care.
Improving heart rate variability after a heart attack
That’s why standard hospital care after a heart attack includes beta blockers, drugs that help the body recover its resilience. But beta blockers work slowly, and some patients cannot tolerate them.
The Yale researchers wondered if a non-pharmacologic intervention might be just as effective, work faster, be safe for all patients–and even help patients feel better?
In the high-tech acute cardiac care setting, why would doctors be interested in patients feeling better? Because subjectively feeling better is known to have objective effects on health. It is well documented that emotional stress negatively affects autonomic nervous system (ANS) function, and therefore heart disease (ANS controls heart rate).
Specifics of the Reiki and heart rate variability study
This randomized, controlled study looked at non-invasive, nondrug interventions to help patients recover faster from a heart attack. The study had three arms:
- Group 1 (12 patients) rested quietly without interruption.
- Group 2 (13 patients) listened to slow tempo, meditative, classical music.
- Group 3 (12 patients) received 20-minute Reiki treatment from Reiki-trained staff nurses.
Patients were measured initially for baseline, and again after the intervention, and the two sets of measurements were compared. The measurements from all groups were then compared to the others.
The impact of the intervention (rest, music, or Reiki) was measured in two ways, emotional state and heart rate variability (HRV), a physiologic measure that indicates if the patient’s body is recovering from the stress response.
The patients rated themselves on both positive states (happy, relaxed, calm) and negative states (stressed, angry, sad, frustrated, worried, scared, anxious).
Reiki study results
Reiki treatment improved all positive emotional states and reduced all negative states. Comparing the three groups, the Reiki group had the most positive changes in emotional state, and the resting control had the least.
Reiki treatment also improved HRV. The benefit shown was comparable to that seen in a study of beta blockers.
Additionally, the study showed that Reiki treatment can be offered in an acute-care setting. This is important. Sometimes interventions are found to be helpful but they are not feasible in a real life care setting. None of the patients experienced any adverse events.
In this study, Reiki treatment significantly improved mood and HRV compared to the resting and music control conditions. Many questions remain unanswered, such as how long does the benefit of a Reiki treatment last?
Much more research is needed. But this is a good start.
