It has been shown that the inspiratory muscles of patients with congestive heart failure (CHF) are weaker than normal. This weakness may contribute to dyspnea and limit exercise capacity. But respiratory muscles can be trained for increase in both strength and endurance. This study was designed to evaluate the effect of specific inspiratory muscle training (SIMT) on muscular performance, lung function, dyspnea and exercise capacity in moderate heart failure. 10 patients with CHF (NYHA functional class II-III) received 1/2 hour of SIMT daily, 6 times/week, for 3 months. They started breathing at a resistance 15% of their Pimax for 1 week and the resistance was then increased incrementally to 60%. Spirometry, inspiratory muscle strength and endurance, and the 12-minute walk test were performed before and after the training period. All showed an increase in inspiratory muscle strength and endurance. This was associated with a small but significant increase in FVC, a significant increase in the distance walked (458 +/- 29 to 562 +/- 32 m, p < 0.01), and improvement in the dyspnea index score. SIMT resulted in increased inspiratory muscle strength and endurance. This increase was associated with decreased dyspnea and an increase in submaximal exercise capacity. SIMT may prove to be useful complementary therapy in CHF.

Music therapy (MT) has been used in geriatric nursing hospitals, but there has been no extensive research into whether it actually has beneficial effects on elderly patients with cerebrovascular disease (CVD) and dementia. We investigated the effects of MT on the autonomic nervous system and plasma cytokine and catecholamine levels in elderly patients with CVD and dementia, since these are related to aging and chronic geriatric disease. We also investigated the effects of MT on congestive heart failure (CHF) events.Eighty-seven patients with pre-existing CVD were enrolled in the study. We assigned patients into an MT group (n = 55) and non-MT group (n = 32). The MT group received MT at least once per week for 45 minutes over 10 times. Cardiac autonomic activity was assessed by heart rate variability (HRV). We measured plasma cytokine and catecholamine levels in both the MT group and non-MT group. We compared the incidence of CHF events between these two groups. In the MT group, rMSSD, pNN50, and HF were significantly increased by MT, whereas LF/HF was slightly decreased. In the non-MT group, there were no significant changes in any HRV parameters. Among cytokines, plasma interleukin-6 (IL-6) in the MT group was significantly lower than those in the non-MT group. Plasma adrenaline and noradrenaline levels were significantly lower in the MT group than in the non-MT group. CHF events were less frequent in the MT group than in the non-MT group (P < 0.05). These findings suggest that MT enhanced parasympathetic activities and decreased CHF by reducing plasma cytokine and catecholamine levels.

The use of yoga as an effective cardiac rehabilitation in patients with chronic heart failure (CHF) remains controversial. We performed a meta-analysis to examine the effects of yoga on exercise capacity and health-related quality of life (HRQOL) in patients with CHF. Methods: We searched MEDLINE, Cochrane Central Register of Controlled Trials, Excerpta Medica database, LILACS, Physiotherapy Evidence Database, The Scientific Electronic Library Online, and Cumulative Index to Nursing and Allied Health (from the earliest date available to December 2013) for randomized controlled trials (RCTs) examining the effects of yoga versus exercise and/or of yoga versus control on exercise capacity (peakVO2) and quality-of-life (HRQOL) in CHF. Two reviewers selected studies independently. Weighted mean differences (WMDs) and 95% confidence intervals (CIs) were calculated, and heterogeneity was assessed using the I2 test. Two studies met the selection criteria (total: 30 yoga and 29 control patients). The results suggested that yoga compared with control had a positive impact on peak VO2 and HRQOL. Peak VO2, WMD (3.87 95% CI: 1.95 to 5.80), and global HRQOL standardized mean differences (-12.46 95% CI: -22.49 to -2.43) improved in the yoga group compared to the control group. Yoga enhances peak VO2 and HRQOL in patients with CHF and could be considered for inclusion in cardiac rehabilitation programs. Larger RCTs are required to further investigate the effects of yoga in patients with CHF.

OBJECTIVE: We tested whether meditation can reduce sympathetic activation, evaluated by norepinephrine blood levels (NE), and improve quality of life in elderly persons with congestive heart failure (CHF). DESIGN AND SETTING: This was a prospective, randomized study conducted from April 2000 to October 2001 in an ambulatory care teaching hospital in São Paulo, Brazil. SUBJECTS: We studied 19 patients with CHF, 74.8 +/- 6.7 years old, receiving diuretics, optimal doses of an angiotensin-converting enzyme inhibitor or angiotensin II inhibitor, maximum tolerated carvedilol dose (23.1 +/- 13.6 mg) and spironolactone 25 mg (10 patients). INTERVENTIONS: After 2 months of optimal treatment with carvedilol, patients were randomized into two groups. The meditation group (M) was provided an audiotape, 30 minutes long, to listen to at home, twice a day, for 12 weeks, plus a weekly meeting. The control group (C) just had weekly meetings. MAIN OUTCOME MEASURES: We determined before and after 14 +/- k1 weeks, NE (in pg/mL); quality of life with the Minnesota Living with Heart Failure Questionnaire (MLWHFQ); VO2 and VE/VCO2 slope by cardiopulmonary exercise testing; left ventricular ejection fraction (LVEF), and left ventricular end-diastolic volume index (LVDDi) measured by echocardiography. RESULTS: Meditation reduced NE (mean +/- SEM) from 677.7 +/- 96.6 to 387.1 +/- 39.1 pg/mL (p = 0.008) in M versus 491.4 +/- 35.9 to 470.6 +/- 31.2 (p = 0.34) in C; improved MLWHFQ total score (mean +/- SEM) from 33.2 +/- 6.6 to 21.6 +/- 6.8 points (p = 0.02) in M versus 18.4 +/- 8.0 to 25.1 +/- 8.9 (p = 0.41) in C; and reduced the VE/VCO2 slope (mean +/- SEM) from 31.2 +/- 3.0 to 28.2 +/- 2.6 (p = 0.04) in M versus 28.4 +/- 2.7 to 28.8 +/- 2.6 (p = 0.24) in C. No changes occurred in LVEF, LVDDi, and VO(2). CONCLUSIONS: In elderly patients with optimally treated CHF, meditation reduced NE, improved quality of life, and reduced the VE/VCO(2) slope. Our results support the possible role of meditation as a new hope in the treatment of CHF.

The main purpose of using diuretics is usually lost sight of, i.e. it is for the relief of dyspnea by using the least amount of a diuretic. The production of a low output state and hypercoagulation in an attempt to achieve dry weight by lowering blood volume excessively are among the hazards of using more diuretic than is absolutely necessary to achieve the goal of relieving dyspnea. The use of jugular venous pressure measurement and the status of dyspnea should have precedence over body weight in determining diuretic dose adjustment. Often forgotten in using diuretics is that potassium without magnesium will not enter cells and that the almost universal preference for furosemide over thiazides threatens to increase the incidence of osteoporosis. Also, the tendency to ignore loss of the water-soluble vitamins thiamine and ascorbic acid may result in refractory edema and the inability to manage the stresses of congestive heart failure.

BACKGROUND: We developed a Waon therapy (soothing warm therapy) and have previously reported that repeated Waon therapy improves hemodynamics, peripheral vascular function, arrhythmias, and clinical symptoms in patients with chronic heart failure (CHF). The aim of this study was to investigate the effect of Waon therapy on the prognosis of CHF patients. PATIENTS AND METHODS: We studied 129 patients with CHF in NYHA functional class III or IV who were admitted to our hospital between January 1999 and March 2001. In the Waon therapy group, 64 patients were treated with a far infrared-ray dry sauna at 60 degrees C for 15min and then kept on bed rest with a blanket for 30min. The patients were treated daily for 5 days during admission, and then at least twice a week after discharge. In the control group, 65 patients, matched for age, gender, and NYHA functional class, were treated with traditional CHF therapy. The follow-up time was scheduled for 5 years. RESULTS: Recent, complete follow-up data on each patient were obtained. The overall survival rate was 84.5% (Kaplan-Meier estimate). Twelve patients died in the control group and 8 patients died in the Waon therapy group at 60 months of follow-up. Cardiac events due to heart failure or cardiac death occurred in 68.7% of the control group but only 31.3% of the Waon therapy group (P<0.01) at 60 months of follow-up. CONCLUSION: Waon therapy reduced cardiac events in patients with CHF. This therapy is a promising non-pharmacological treatment for CHF.
