BACKGROUND: Many common medical, surgical, and diagnostic procedures performed for conscious patients can be accompanied by significant anxiety. Mind-body-spirit interventions could serve as useful adjunctive treatments for the reduction of stress. OBJECTIVE: To evaluate the effects of stress management, imagery, touch therapy, remote intercessory prayer, and standard therapy on mood in patients awaiting percutaneous interventions for unstable coronary syndromes as part of the Monitoring and Actualization of Noetic Training (MANTRA) trial, which explored the feasibility and efficacy of noetic interventions on clinical outcomes in a randomized clinical trial. METHODS: A total of 150 patients were randomized to one of the five treatment conditions. Stress management, imagery, and touch therapy were administered in 30-minute treatment sessions immediately before the cardiac intervention. Intercessory prayer was not necessarily contemporaneous with these treatments. Mood was assessed by a set of visual analog scales before and after treatment for a similar length of time for the standard therapy and prayer groups. RESULTS: Analysis of complete data from 108 patients showed that stress management, imagery, and touch therapy all produced reductions in reported worry, as compared with standard therapy, whereas remote intercessory prayer had no effect on mood. The ratings of other similar moods were not affected, perhaps because of the relatively positive emotional state observed in the participants before treatment. CONCLUSIONS: The results suggest that at least some noetic therapies may have beneficial effects on mood in the course of medical and surgical interventions. Administration of these interventions was feasible even in the hectic environment of the coronary intensive care unit. Given their relatively low cost and limited potential for adverse effects, these interventions merit further study as therapeutic adjuncts.

We studied the relationship between mood and mood shift immediately before percutaneous coronary intervention (PCI) and 3 end points: total ischemic burden during PCI, adverse cardiac end points (ACE) after PCI, and death by 6-month follow up. Patients (n = 119) with unstable angina or myocardial infarction completed a visual analog scale (VAS) twice before PCI; before and after a session of stress relaxation, imagery, or touch; or approximately 30 minutes apart for patients assigned to prayer or to standard care. VAS included happiness, satisfaction, calm, hope, worry, shortness of breath, fear, and sadness. We observed a significant correlation between higher hope score before PCI and lower ischemic burden. Patients who experienced ACE had significantly lower hope and happiness scores than those who did not. Patients who survived to 6 months had significantly greater increases in worry and in hope. Our data suggest correlations between simple mood assessments before PCI and clinical outcomes during and after the procedure. More study is needed to understand whether attempts to alter patient mood can affect clinical outcomes.

Integrative noetic therapies as adjuncts to percutaneous intervention during unstable coronary syndromes: The Monitoring & Actualization of Noetic TRAinings (MANTRA) Feasibility Pilot Study. AMERICAN HEART JOURNAL, 2001, 142, 760-767.
BACKGROUND: Patients undergoing percutaneous coronary intervention (PCI) for unstable coronary syndromes have substantial emotional and spiritual distress that may promote procedural complications. Noetic (nonpharmacologic) therapies may reduce anxiety, pain and distress, enhance the efficacy of pharmacologic agents, or affect short- and long-term procedural outcomes. METHODS: The Monitoring and Actualization of Noetic Training (MANTRA) pilot study examined the feasibility of applying 4 noetic therapies-stress relaxation, imagery, touch therapy, and prayer-to patients in the setting of acute coronary interventions. Eligible patients had acute coronary syndromes and invasive angiography or PCI. Patients were randomized across 5 treatment groups: the 4 noetic and standard therapies. Questionnaires completed before PCI reflected patients' religious beliefs and anxiety. Index hospitalization end points included post-PCI ischemia, death, myocardial infarction, heart failure, and urgent revascularization. Mortality was followed up for 6 months after hospitalization. RESULTS: Of eligible patients, 88% gave informed consent. Of 150 patients enrolled, 120 were assigned to noetic therapy; 118 (98%) completed their therapeutic assignments. All clinical end points were available for 100% of patients. Results were not statistically significant for any outcomes comparisons. There was a 25% to 30% absolute reduction in adverse periprocedural outcomes in patients treated with any noetic therapy compared with standard therapy. The lowest absolute complication rates were observed in patients assigned to off-site prayer. All mortality by 6-month follow-up was in the noetic therapies group. In patients with questionnaire scores indicating a high level of spiritual belief, a high level of personal spiritual activity, a low level of community-based religious involvement, or a high level of anxiety, noetic therapies appeared to show greater reduction in absolute in-hospital complication rates compared with standard therapy. CONCLUSIONS: Acceptance of noetic adjuncts to invasive therapy for acute coronary syndromes was excellent, and logistics were feasible. No outcomes differences were significant; however, index hospitalization data consistently suggested a therapeutic benefit with noetic therapy. Of all noetic therapies, off-site intercessory prayer had the lowest short- and long-term absolute complication rates. Definitive demonstration of treatment effects of this magnitude would be feasible in a patient population about 4 times that of this pilot study. Absolute mortality differences make safety considerations a mandatory feature of future clinical trials in this area.
Lane, J. D., Kasian, S. J., Owens, J. E. and Marsh, G. R. (1998). "Binaural auditory beats affect vigilance performance and mood." Physiology & Behavior 63(2): 249-52.When two tones of slightly different frequency are presented separately to the left and right ears the listener perceives a single tone that varies in amplitude at a frequency equal to the frequency difference between the two tones, a perceptual phenomenon known as the binaural auditory beat. Anecdotal reports suggest that binaural auditory beats within the electroencephalograph frequency range can entrain EEG activity and may affect states of consciousness, although few scientific studies have been published. This study compared the effects of binaural auditory beats in the EEG beta and EEG theta/delta frequency ranges on mood and on performance of a vigilance task to investigate their effects on subjective and objective measures of arousal. Participants (n = 29) performed a 30-min visual vigilance task on three different days while listening to pink noise containing simple tones or binaural beats either in the beta range (16 and 24 Hz) or the theta/delta range (1.5 and 4 Hz). However, participants were kept blind to the presence of binaural beats to control expectation effects. Presentation of beta-frequency binaural beats yielded more correct target detections and fewer false alarms than presentation of theta/delta frequency binaural beats. In addition, the beta-frequency beats were associated with less negative mood. Results suggest that the presentation of binaural auditory beats can affect psychomotor performance and mood. This technology may have applications for the control of attention and arousal and the enhancement of human performance.
